Display and controller solution support for engineering-driven projects.
Selected products can be customized with options including cover glass, backlight, optical enhancement films, and touch solutions. Contact us for engineering support and customized display solutions.
Display and controller board projects usually require more than a model number. RJY can review your technical requirements before sample or quotation discussion.
Check display size, resolution, brightness, viewing angle, touch requirement, and operating environment.
Review interface type, pin definition, controller board requirement, driver IC, and system compatibility.
Discuss cover glass, backlight, touchscreen, FPC, firmware, and mechanical coordination when needed.
Prepare application details, sample quantity, annual demand, target timeline, datasheet, or reference product.
