Display Requirements and Challenges

Key RequirementsTarget Specification
Display TypeTFT LCD module, 2.8-inch
Разрешение480×480 (square)
ИнтерфейсRGB + SPI for flexible MCU integration
Яркость≥ 400 cd/m² (sunlight readable)
Touch CapabilityCapacitive (optional SKU)
Рабочая температура–20°C to +70°C
Угол обзораAll O’Clock (IPS-like experience)
Mounting SpaceMinimal dashboard footprint

The main challenge was finding a display that combined optical clarity, industrial temperature tolerance, and compact size—without exceeding the BOM budget.

Solution: Custom Integration of RJY 2.8-Inch TFT eBike LCD Display

RJY Display recommended its 2.8-inch AM TFT transmissive LCD, model #RJY-280480IPS-RGBSPI, which checked all the boxes:

✅ Product Highlights

  • Разрешение: 480×480 pixel square layout, perfect for circular speed dials and segmented UI
  • Яркость: 400 cd/m², readable under daylight and streetlight conditions
  • Угол обзора: All-direction O’Clock viewing ensures clarity from any rider position
  • Интерфейс: RGB + SPI hybrid interface simplifies connection to MCU/driver boards
  • Touch (Optional): PCAP with glass bonding for gesture interaction or glove support
  • Wide Temp Range: Reliable operation from –20°C to +70°C—ideal for outdoor climates
  • Compact Profile: Fits neatly into a minimal front-mount eBike controller enclosure

📐 Integration Support from RJY

RJY’s team provided:

  • Custom FPC routing design to match the client’s PCB layout
  • Optional touch firmware tuning for winter glove support
  • Frame bonding guidance for IP65-level sealing during mass production
  • Pre-aging and outdoor simulation testing to validate field durability
  • Fully compatible with the customer’s electric bicycle on-board computer

User Interface Example

The 480×480 resolution was leveraged to create:

  • Central digital speedometer in circular layout
  • Battery percentage + health bar
  • Bluetooth/connection status
  • Light and turn signal icons
  • Temperature and error code readouts

The full-color TFT allowed dynamic changes in UI themes based on ride mode: Eco, Sport, and Turbo.

Project Outcome

📈 After implementation, the client reported:

  • 36% fewer warranty claims related to display malfunction
  • Faster assembly time due to pre-bonded modules with matched FPC
  • Increased rider satisfaction based on survey feedback from end users
  • Improved aesthetics and brand differentiation in a crowded eBike market
