Display Requirements and Challenges
| Key Requirements | Target Specification |
|---|---|
| Display Type | TFT LCD module, 2.8-inch |
| Resolution | 480×480 (square) |
| Interface | RGB + SPI for flexible MCU integration |
| Brightness | ≥ 400 cd/m² (sunlight readable) |
| Touch Capability | Capacitive (optional SKU) |
| Operating Temperature | –20°C to +70°C |
| Viewing Angle | All O’Clock (IPS-like experience) |
| Mounting Space | Minimal 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
- Resolution: 480×480 pixel square layout, perfect for circular speed dials and segmented UI
- Brightness: 400 cd/m², readable under daylight and streetlight conditions
- View Angle: All-direction O’Clock viewing ensures clarity from any rider position
- Interface: 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
