Display Requirements and Challenges

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
