The quotation reflects the complete product path: whether an existing module is available, how the active area and cover glass are formed, whether touch is required, which interface and controller platform are used, and how much mechanical or firmware adaptation the project needs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There is no reliable universal percentage for the price premium. A catalog round TFT LCD used with its existing interface and mechanical structure may be relatively straightforward. A project that requires a different cover lens, touch stack, FPC, backlight, controller board, firmware configuration, or enclosure arrangement will have a different cost structure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For an OEM buyer, the useful question is not simply, \u201cWhy is a round display expensive?\u201d It is, \u201cWhich parts of our proposed round display system create cost, and which requirements can be aligned with an existing platform?\u201d<\/p>\n\n\n\n<h2 id=\"the-short-answer-round-lcd-cost-is-a-system-cost\" class=\"wp-block-heading\">The Short Answer: Round LCD Cost Is a System Cost<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A rectangular display benefits from a broad range of established module sizes, interfaces, touch options, enclosures, controller boards, and software examples. Round displays serve a narrower set of product formats, so the exact combination required by an OEM may be available in fewer standard configurations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This difference can affect four parts of the project budget:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Budget Area<\/th><th>What It Includes<\/th><th>Why It Matters<\/th><\/tr><\/thead><tbody><tr><td>Module cost<\/td><td>LCD cell, backlight, driver IC, FPC, frame, and standard testing<\/td><td>Availability and production scale vary by model<\/td><\/tr><tr><td>Customization cost<\/td><td>Cover glass, touch, backlight, FPC, connector, interface, or mechanical coordination<\/td><td>Non-standard parts may require engineering and tooling<\/td><\/tr><tr><td>Integration cost<\/td><td>Controller board, PCB routing, initialization, drivers, UI work, and touch mapping<\/td><td>A lower module price does not compensate for an incompatible system architecture<\/td><\/tr><tr><td>Production risk<\/td><td>Qualification, assembly, supply continuity, revision control, and replacement planning<\/td><td>Late design changes can cost more than the initial display difference<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 id=\"first-define-what-round-means\" class=\"wp-block-heading\">First Define What \u201cRound\u201d Means<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Product descriptions often use \u201cround display\u201d for several different structures. The active image may be circular while the LCD glass, backlight housing, or module outline remains approximately square. Another product may use a circular cover glass over a rectangular display. These structures are not mechanically or economically equivalent.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before comparing quotations, distinguish among:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Active area:<\/strong> the pixel area that generates the image<\/li>\n\n\n\n<li><strong>Viewing area:<\/strong> the portion visible through the bezel or cover glass<\/li>\n\n\n\n<li><strong>LCD glass outline:<\/strong> the physical cell dimensions<\/li>\n\n\n\n<li><strong>Module outline:<\/strong> the complete backlight and frame dimensions<\/li>\n\n\n\n<li><strong>Cover-glass outline:<\/strong> the external lens shape seen by the user<\/li>\n\n\n\n<li><strong>Touch active area:<\/strong> the area in which touch input is detected<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A circular cover lens does not automatically mean that the LCD cell has a circular outline. Likewise, a square 480 \u00d7 480 or 1080 \u00d7 1080 pixel matrix does not prove that every corner is visible. The mechanical drawing should identify the actual active area, viewing area, module outline, FPC location, and mounting constraints.<\/p>\n\n\n\n<h2 id=\"cost-driver-1-existing-module-availability\" class=\"wp-block-heading\">Cost Driver 1: Existing Module Availability<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The lowest-risk route is normally to begin with an existing round LCD module whose size, resolution, interface, brightness, and mechanical structure are already reasonably close to the product requirement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">RJY Display\u2019s current <a href=\"https:\/\/rjydisplay.com\/round-display\/\">round display category<\/a> illustrates why the exact model matters. The published range includes different diameters, resolutions, brightness levels, touch configurations, and interfaces rather than one interchangeable round-screen standard.<sup><a href=\"#ref-1\">[1]<\/a><\/sup><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Published Product Path<\/th><th>Published Resolution<\/th><th>Published Interface<\/th><th>Engineering Use of the Example<\/th><\/tr><\/thead><tbody><tr><td><a href=\"https:\/\/rjydisplay.com\/product\/2-8-inch-round-tft-lcd-display\/\">2.8-inch round TFT LCD<\/a><\/td><td>480 \u00d7 480<\/td><td>RGB + SPI<\/td><td>Compact MCU or embedded display evaluation<\/td><\/tr><tr><td><a href=\"https:\/\/rjydisplay.com\/product\/4-inch-round-touch-tft-lcd-display\/\">4-inch round touch TFT LCD<\/a><\/td><td>720 \u00d7 720<\/td><td>RGB<\/td><td>Touch-enabled HMI evaluation<\/td><\/tr><tr><td><a href=\"https:\/\/rjydisplay.com\/product\/7-inch-round-tft-lcd-display\/\">7-inch round TFT LCD<\/a><\/td><td>1080 \u00d7 1080<\/td><td>LVDS<\/td><td>Larger embedded or equipment HMI evaluation<\/td><\/tr><tr><td><a href=\"https:\/\/rjydisplay.com\/product\/8-inch-round-lcd-display\/\">8-inch round LCD<\/a><\/td><td>1080 \u00d7 1080<\/td><td>MIPI<\/td><td>MIPI-based application-processor evaluation<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">These examples should be treated as starting points, not proof of compatibility. The current datasheet, pin definition, driver IC, timing, power requirements, touch configuration, and mechanical drawing still need to be reviewed before sampling.<\/p>\n\n\n\n<h2 id=\"cost-driver-2-panel-layout-and-production-scale\" class=\"wp-block-heading\">Cost Driver 2: Panel Layout and Production Scale<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Flat-panel manufacturing begins with large glass substrates and carefully planned panel layouts. Corning\u2019s description of its Gen 10.5 LCD glass facility notes that substrate dimensions were selected to provide economical cuts for specific large television formats, illustrating how substrate layout and repeatable production scale affect display economics.<sup><a href=\"#ref-2\">[2]<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This does not mean that every round LCD is simply cut out of a rectangular finished panel, nor does it justify a fixed glass-utilization percentage for every round module. The actual structure depends on the panel design and manufacturing process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The practical purchasing implication is simpler: a display platform produced repeatedly for several customers generally has a different cost structure from a low-volume platform requiring unique masks, components, fixtures, or assembly processes. The supplier should confirm whether the proposed display is an existing product, an existing product with surrounding modifications, or a request that would require a substantially new platform.<\/p>\n\n\n\n<h2 id=\"cost-driver-3-touchscreen-and-coverglass-integration\" class=\"wp-block-heading\">Cost Driver 3: Touchscreen and Cover-Glass Integration<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Touch cost depends on more than whether the quotation says \u201ccapacitive touch.\u201d A round user interface may require coordination among the sensor geometry, touch controller, cover-glass outline, printed border, bonding stack, FPC exit, enclosure opening, and touch-coordinate system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Touch electrodes can use different shapes. Microchip\u2019s capacitive touch design guide notes that round and rectangular electrodes are common and that other shapes may be used when sufficient contact area is maintained.<sup><a href=\"#ref-3\">[3]<\/a><\/sup> In a finished touchscreen, however, the sensor layout and controller configuration must still be evaluated for the actual screen size, cover structure, electrical environment, and user interaction.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Touch Requirement<\/th><th>Possible Cost Effect<\/th><th>Cost-Control Question<\/th><\/tr><\/thead><tbody><tr><td>Standard touch option for an existing module<\/td><td>Uses an established display-touch combination<\/td><td>Can the standard touch outline and FPC be retained?<\/td><\/tr><tr><td>Custom cover glass<\/td><td>May add drawing review, artwork, tooling, and sample validation<\/td><td>Can the enclosure accept an existing cover-glass outline?<\/td><\/tr><tr><td>Different touch active area<\/td><td>May require sensor and controller re-evaluation<\/td><td>Is full-edge interaction necessary, or can controls remain inside a safe zone?<\/td><\/tr><tr><td>Thicker lens or unusual operating conditions<\/td><td>May require touch tuning and system testing<\/td><td>What lens thickness and real use conditions must be supported?<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Touch communication should also be treated separately from the display video interface. A display may use RGB, LVDS, or MIPI while the touch controller communicates with the host through I2C, USB, or another supported path.<\/p>\n\n\n\n<h2 id=\"cost-driver-4-resolution-interface-and-host-platform\" class=\"wp-block-heading\">Cost Driver 4: Resolution, Interface, and Host Platform<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Higher resolution can increase pixel-processing, memory, interface-bandwidth, and software requirements, but resolution alone does not determine the final quotation. The host processor must generate a format that matches the LCD timing and interface.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Interface Route<\/th><th>Typical System Consideration<\/th><th>What Must Be Confirmed<\/th><\/tr><\/thead><tbody><tr><td>SPI<\/td><td>Lower pin count for compact MCU systems and simpler graphics<\/td><td>Frame-update requirement, driver support, pixel format, and initialization<\/td><\/tr><tr><td>RGB<\/td><td>Direct parallel display connection<\/td><td>Pin count, timing, PCB routing, frame buffer, and controller support<\/td><\/tr><tr><td>LVDS<\/td><td>Common in larger embedded display systems<\/td><td>Channel configuration, mapping, voltage, timing, and connector definition<\/td><\/tr><tr><td>MIPI DSI<\/td><td>High-speed serial connection for compatible processors and bridge systems<\/td><td>Lane count, timing, mode, initialization, power sequence, and firmware support<\/td><\/tr><tr><td>Controller-board route<\/td><td>Converts or manages a host output for a supported panel<\/td><td>Exact panel compatibility, firmware, touch path, backlight, and input mode<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">MIPI DSI integration demonstrates why interface labels alone are insufficient. NXP\u2019s application note for a DSI display system includes configuration of panel power, reset, backlight GPIO, timing parameters, signal polarity, and the DSI host\u2014not just connection of the data lanes.<sup><a href=\"#ref-4\">[4]<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If an existing round module already matches the processor output, the project may avoid an additional bridge or controller. If it does not match, compare the cost of changing the display, changing the host platform, or adding a suitable controller-board path. The least expensive module is not necessarily the least expensive system.<\/p>\n\n\n\n<h2 id=\"cost-driver-5-circular-ui-and-firmware-work\" class=\"wp-block-heading\">Cost Driver 5: Circular UI and Firmware Work<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A square-resolution frame buffer can still drive a circular visible interface, but the UI must be designed around the actual visible area. Text, status indicators, touch targets, warnings, and navigation controls should not be placed in clipped or inaccessible corner regions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Embedded graphics frameworks can support many processors and display types. LVGL, for example, describes its graphics library as hardware-independent and suitable for MCU- and MPU-based display systems.<sup><a href=\"#ref-5\">[5]<\/a><\/sup> That portability does not automatically complete the round-screen design. The product team must still validate:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The visible circular boundary and UI safe area<\/li>\n\n\n\n<li>Touch-coordinate mapping and rejected corner input<\/li>\n\n\n\n<li>Rotation and screen orientation<\/li>\n\n\n\n<li>Frame-buffer and memory requirements<\/li>\n\n\n\n<li>Display initialization and sleep behavior<\/li>\n\n\n\n<li>Boot graphics, operating-system drivers, and application layout<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Reusing an existing driver and initialization path generally reduces engineering work. Requesting a different display driver IC, interface, orientation, or operating-system integration can change the firmware scope and should be discussed before the quote is treated as complete.<\/p>\n\n\n\n<h2 id=\"cost-driver-6-backlight-and-optical-requirements\" class=\"wp-block-heading\">Cost Driver 6: Backlight and Optical Requirements<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Brightness should be selected for the real viewing environment rather than maximized by default. Increasing brightness can affect LED selection, backlight power, thermal behavior, enclosure ventilation, and system power budgeting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For cost evaluation, define whether the display will be used indoors, near strong ambient light, outdoors, inside a vehicle-related device, or behind additional cover material. Also specify the required viewing directions and whether the display will normally be viewed directly or from multiple positions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An existing backlight configuration is normally easier to evaluate than a new brightness target. When a change is necessary, the supplier should review it against the existing module instead of assuming that any brightness value can be produced without electrical or mechanical consequences.<\/p>\n\n\n\n<h2 id=\"cost-driver-7-mechanical-design-and-assembly\" class=\"wp-block-heading\">Cost Driver 7: Mechanical Design and Assembly<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Round displays often create an enclosure that looks symmetrical from the front but is not symmetrical internally. The FPC may exit from one side, the connector may require a defined insertion direction, and the backlight or frame may extend beyond the visible circular boundary.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The mechanical drawing should be reviewed for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Module outline and thickness<\/li>\n\n\n\n<li>Active-area and viewing-area position<\/li>\n\n\n\n<li>Cover-glass diameter and border<\/li>\n\n\n\n<li>FPC direction, length, and bend allowance<\/li>\n\n\n\n<li>Connector position and assembly access<\/li>\n\n\n\n<li>Support surfaces and adhesive areas<\/li>\n\n\n\n<li>Clearance around glass, components, and the FPC<\/li>\n\n\n\n<li>Enclosure tolerances and expected assembly process<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A mechanically incompatible standard module can create more redesign expense than a carefully selected semi-custom solution. Display selection and enclosure design should therefore be reviewed together before tooling for the final housing is released.<\/p>\n\n\n\n<h2 id=\"standard-semicustom-or-new-platform\" class=\"wp-block-heading\">Standard, Semi-Custom, or New Platform?<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Project Route<\/th><th>Appropriate When<\/th><th>Relative Engineering Scope<\/th><\/tr><\/thead><tbody><tr><td>Existing standard round module<\/td><td>The module already matches the size, interface, brightness, touch, and mechanical requirements<\/td><td>Compatibility review and system validation<\/td><\/tr><tr><td>Existing module with customization<\/td><td>The core LCD is suitable but the project needs changes around cover glass, touch, backlight, FPC, interface coordination, controller board, firmware, or mechanics<\/td><td>Defined customization and sample validation<\/td><\/tr><tr><td>Substantially new display platform<\/td><td>No existing module can satisfy the fundamental size or panel requirement<\/td><td>Much broader feasibility, tooling, qualification, volume, and lifecycle review<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">RJY Display\u2019s practical customization path should begin with an existing display module. Customization may coordinate the cover glass, backlight, touch panel, interface, FPC, controller board, firmware, and mechanical structure around that platform. It should not be interpreted as a promise to create any arbitrary new LCD diameter or resolution from scratch.<\/p>\n\n\n\n<h2 id=\"how-to-reduce-round-lcd-display-cost-without-weakening-the-product\" class=\"wp-block-heading\">How to Reduce Round LCD Display Cost Without Weakening the Product<\/h2>\n\n\n\n<h3 id=\"choose-the-display-before-freezing-the-enclosure\" class=\"wp-block-heading\">Choose the display before freezing the enclosure<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If the enclosure is still flexible, review available module outlines and FPC directions before finalizing the front opening, PCB location, and internal supports. Designing around a proven module usually creates more options than searching for a display after the housing is fixed.<\/p>\n\n\n\n<h3 id=\"separate-required-features-from-preferred-features\" class=\"wp-block-heading\">Separate required features from preferred features<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Define which requirements are mandatory and which can change. A specific active diameter may be mandatory, while the cover-glass outer diameter, interface, brightness target, or connector position may have some flexibility. This distinction helps engineering teams compare viable platforms rather than reject them for non-critical differences.<\/p>\n\n\n\n<h3 id=\"match-resolution-to-the-ui-and-processor\" class=\"wp-block-heading\">Match resolution to the UI and processor<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Use the lowest resolution that still supports the required text, graphics, viewing distance, and user experience. The <a href=\"https:\/\/rjydisplay.com\/display-parameter-calculator\/\">TFT LCD parameter calculator<\/a> can provide an initial PPI and pixel-pitch estimate, but the result should be checked with the actual UI artwork and viewing conditions.<\/p>\n\n\n\n<h3 id=\"reuse-an-established-interface-and-software-path\" class=\"wp-block-heading\">Reuse an established interface and software path<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If the host already supports a display interface and validated driver architecture, prioritize modules that fit that path. Changing both the display and the processor interface at the same time increases the number of variables in sample debugging.<\/p>\n\n\n\n<h3 id=\"request-one-systemlevel-quotation\" class=\"wp-block-heading\">Request one system-level quotation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A useful comparison includes the LCD module, touch option, cover glass, required customization, controller-board requirement, firmware scope, sample work, and expected production quantity. Comparing bare-panel prices while ignoring integration scope can produce a misleading purchasing decision.<\/p>\n\n\n\n<h2 id=\"what-to-send-for-a-round-lcd-quotation\" class=\"wp-block-heading\">What to Send for a Round LCD Quotation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Prepare the following information so the supplier can distinguish a standard module request from a customization or integration project:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Target application and country or market<\/li>\n\n\n\n<li>Preferred display diameter and acceptable range<\/li>\n\n\n\n<li>Required resolution and UI examples<\/li>\n\n\n\n<li>Host processor, control board, or video source<\/li>\n\n\n\n<li>Preferred and available display interfaces<\/li>\n\n\n\n<li>Touch requirement and host-side touch interface<\/li>\n\n\n\n<li>Cover-glass drawing or enclosure opening<\/li>\n\n\n\n<li>Brightness and viewing environment<\/li>\n\n\n\n<li>FPC direction and connector constraints<\/li>\n\n\n\n<li>Operating and storage environment<\/li>\n\n\n\n<li>Firmware or operating-system requirements<\/li>\n\n\n\n<li>Prototype quantity, expected annual demand, and project stage<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If an existing product is being replaced, include the original display model, datasheet, mechanical drawing, pin definition, initialization code, and photographs of the installed assembly.<\/p>\n\n\n\n<h2 id=\"request-a-round-lcd-cost-and-compatibility-review\" class=\"wp-block-heading\">Request a Round LCD Cost and Compatibility Review<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">RJY Display can review an existing round LCD platform against your size, resolution, interface, touch, cover-glass, backlight, FPC, controller-board, firmware, and mechanical requirements. The review is based on the actual module and project documentation rather than a general price premium for all round displays.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/rjydisplay.com\/round-display\/\">Browse current round LCD modules<\/a> or <a href=\"https:\/\/rjydisplay.com\/contact\/\">send your project requirements for engineering review<\/a>.<\/p>\n\n\n\n<h2 id=\"faq\" class=\"wp-block-heading\">FAQ<\/h2>\n\n\n\n<h3 id=\"are-round-lcd-displays-always-more-expensive-than-rectangular-displays\" class=\"wp-block-heading\">Are round LCD displays always more expensive than rectangular displays?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No. Price depends on the exact module, availability, size, resolution, interface, touch configuration, brightness, customization scope, order volume, and integration work. An existing catalog round module may be more economical than a rectangular module that requires extensive mechanical or electronic adaptation.<\/p>\n\n\n\n<h3 id=\"is-a-circular-cover-glass-the-same-as-a-truly-round-lcd\" class=\"wp-block-heading\">Is a circular cover glass the same as a truly round LCD?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No. A circular cover glass can be placed over a rectangular or square display structure. Confirm the LCD active area, viewing area, glass outline, module outline, and cover-glass outline separately from the mechanical drawing.<\/p>\n\n\n\n<h3 id=\"can-rjy-create-any-custom-round-lcd-size-from-scratch\" class=\"wp-block-heading\">Can RJY create any custom round LCD size from scratch?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No. RJY\u2019s practical customization approach starts from an existing display module and coordinates areas such as cover glass, backlight, touch, interface, FPC, controller board, firmware, and mechanical structure. Feasibility depends on the available module platform and project requirements.<\/p>\n\n\n\n<h3 id=\"which-factors-have-the-greatest-effect-on-a-round-lcd-quotation\" class=\"wp-block-heading\">Which factors have the greatest effect on a round LCD quotation?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The main factors are module availability, display size and resolution, touch and cover-glass requirements, interface compatibility, brightness and backlight requirements, mechanical changes, firmware work, controller-board requirements, qualification scope, and expected production volume.<\/p>\n\n\n\n<h3 id=\"does-a-higherresolution-round-lcd-always-cost-more\" class=\"wp-block-heading\">Does a higher-resolution round LCD always cost more?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Not always. Resolution can affect the panel, interface, memory, processor, and software requirements, but product availability and integration scope also matter. A widely available higher-resolution module may be more practical than a lower-resolution module requiring extensive customization.<\/p>\n\n\n\n<h3 id=\"what-information-should-i-provide-for-a-round-lcd-quote\" class=\"wp-block-heading\">What information should I provide for a round LCD quote?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Provide the target size, resolution, application, host processor or control board, interface, touch requirement, cover-glass or enclosure drawing, brightness and environment, FPC constraints, firmware requirements, prototype quantity, expected annual demand, and project schedule.<\/p>\n\n\n\n<h2 id=\"references\" class=\"wp-block-heading\">References<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li>RJY Display, \u201cRound Display.\u201d <a href=\"https:\/\/rjydisplay.com\/round-display\/\">https:\/\/rjydisplay.com\/round-display\/<\/a><\/li>\n\n\n\n<li>Corning Incorporated, \u201cWorld\u2019s Largest LCD Glass Facility Opens in China.\u201d <a href=\"https:\/\/www.corning.com\/worldwide\/en\/about-us\/news-events\/news-releases\/2018\/05\/corning-opens-worlds-largest-lcd-glass-substrate-facility-in-china.html\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">https:\/\/www.corning.com\/worldwide\/en\/about-us\/news-events\/news-releases\/2018\/05\/corning-opens-worlds-largest-lcd-glass-substrate-facility-in-china.html<\/a><\/li>\n\n\n\n<li>Microchip Technology, \u201cAN2934: Capacitive Touch Sensor Design Guide.\u201d <a href=\"https:\/\/ww1.microchip.com\/downloads\/aemDocuments\/documents\/TXFG\/ApplicationNotes\/ApplicationNotes\/Capacitive-Touch-Sensor-Design-Guide-DS00002934-B.pdf\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">https:\/\/ww1.microchip.com\/downloads\/aemDocuments\/documents\/TXFG\/ApplicationNotes\/ApplicationNotes\/Capacitive-Touch-Sensor-Design-Guide-DS00002934-B.pdf<\/a><\/li>\n\n\n\n<li>NXP Semiconductors, \u201cAN12940: Use Case of RT1170 LCD Display System Based on MIPI DSI.\u201d <a href=\"https:\/\/www.nxp.com\/docs\/en\/application-note\/AN12940.pdf\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">https:\/\/www.nxp.com\/docs\/en\/application-note\/AN12940.pdf<\/a><\/li>\n\n\n\n<li>LVGL, \u201cLVGL Documentation.\u201d <a href=\"https:\/\/lvgl.io\/docs\/open\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">https:\/\/lvgl.io\/docs\/open\/<\/a><\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"<p>\u8868\u793a\u6280\u8853\u306e\u9032\u5316\u306b\u4f34\u3044\u3001\u30e1\u30fc\u30ab\u30fc\u306f\u5e73\u9762\u306e\u9577\u65b9\u5f62\u30b9\u30af\u30ea\u30fc\u30f3\u304b\u3089\u3001\u9769\u65b0\u7684\u306a\u5186\u5f62LCD\u8868\u793a\u5668\uff08\u30b5\u30fc\u30ad\u30e5\u30e9\u30fc\u30c7\u30a3\u30b9\u30d7\u30ec\u30a4\u3068\u3082\u547c\u3070\u308c\u308b\uff09\u3078\u3068\u7126\u70b9\u3092\u79fb\u3057\u3064\u3064\u3042\u308a\u307e\u3059\u3002\u7f8e\u7684\u9b45\u529b\u3068\u4eba\u9593\u5de5\u5b66\u7684\u306a\u53ef\u80fd\u6027\u3092\u79d8\u3081\u308b\u4e00\u65b9\u3067\u3001\u5186\u5f62LCD\u306f\u5f93\u6765\u306e\u9577\u65b9\u5f62\u8868\u793a\u5668\u3068\u6bd4\u8f03\u3057\u3066\u9855\u8457\u306a\u30b3\u30b9\u30c8\u30d7\u30ec\u30df\u30a2\u30e0\u304c\u751f\u3058\u307e\u3059\u3002<\/p>","protected":false},"author":2,"featured_media":43401,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[438],"tags":[514],"class_list":["post-43394","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-knowledge","tag-display-modules"],"blocksy_meta":[],"_links":{"self":[{"href":"https:\/\/rjydisplay.com\/ja\/wp-json\/wp\/v2\/posts\/43394","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/rjydisplay.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/rjydisplay.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/rjydisplay.com\/ja\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/rjydisplay.com\/ja\/wp-json\/wp\/v2\/comments?post=43394"}],"version-history":[{"count":4,"href":"https:\/\/rjydisplay.com\/ja\/wp-json\/wp\/v2\/posts\/43394\/revisions"}],"predecessor-version":[{"id":46017,"href":"https:\/\/rjydisplay.com\/ja\/wp-json\/wp\/v2\/posts\/43394\/revisions\/46017"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/rjydisplay.com\/ja\/wp-json\/wp\/v2\/media\/43401"}],"wp:attachment":[{"href":"https:\/\/rjydisplay.com\/ja\/wp-json\/wp\/v2\/media?parent=43394"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/rjydisplay.com\/ja\/wp-json\/wp\/v2\/categories?post=43394"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/rjydisplay.com\/ja\/wp-json\/wp\/v2\/tags?post=43394"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
