2.8-Inch TFT LCD Display Integration in Smart eBike Dashboard System
In the rapidly evolving electric mobility sector, delivering a reliable and intuitive user interface is essential to enhancing rider experience and safety. This case study explores how RJY Display partnered with a leading electric bicycle manufacturer to design and implement a 2.8-inch ebike LCD display, offering real-time data visualization in a compact, rugged, and sunlight-readable form factor.
Project Background
The client, a European-based startup in the eMobility sector, aimed to upgrade their eBike dashboard with:
- A vibrant and high-resolution display
- Compact mechanical footprint
- Wide viewing angles for all rider positions
- Stable operation across diverse outdoor environments
- Optional touch interface for enhanced interaction
Their target market included urban commuters, rental fleet operators, and long-distance trail riders, necessitating a display solution with durability, clarity, and customization flexibility.

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
Why This eBike LCD Display Works
| Feature | Impact for eBike Use |
|---|---|
| Square Resolution | Efficient layout for circular UI + digital data |
| High Brightness | Excellent readability in variable lighting |
| Wide Temperature | All-season, global region usability |
| Flexible Interface | Easy driver integration with MCU |
| Optional Touch | Next-gen interactivity on higher-end models |
