Introduction: Automotive Displays Enter a New Era
As automotive technology evolves, displays are no longer just dashboards — they are critical interfaces for safety, infotainment, and comfort. Automakers are investing heavily in TFT LCD modules that balance durability, cost efficiency, and visual clarity. Truly Semiconductors, with its G5 production line and innovations in a-Si TFT and GIP technology, is emerging as a key display manufacturer for next-generation vehicles.

Inside Truly’s New 9.2” TFT Module
One of the most exciting additions to Truly’s automotive lineup is the 9.2-inch TFT e-mirror module, featuring a 1920×384 resolution, a single IC driver with GIP integration, and an ultra-narrow bezel.
This design focuses on:
- Slim architecture for seamless automotive integration
- Cost-effectiveness for OEM scalability
- High reliability through proven a-Si TFT performance
Truly’s engineering teams have optimized the balance between readability and efficiency, ensuring that automotive manufacturers can trust its displays for long-term vehicle deployment.
These modules integrate GIP (Gate-in-Panel) technology, eliminating external driver ICs, reducing complexity, and allowing slimmer borders—perfect for modern, bezel-free designs.
a-Si TFT vs. GIP Technology: What’s the Difference?
When discussing automotive displays, a-Si TFT and GIP technology often appear together, but they refer to different aspects of display design:
a-Si TFT (Amorphous Silicon Thin-Film Transistor) is a semiconductor material and process used in TFT substrates. It is widely adopted for automotive displays because of its cost efficiency, stability, and long production cycles, making it suitable for dashboards and e-mirrors. Learn more in our deep dive on LTPS TFT vs. a-Si automotive HUD displays.
GIP (Gate-in-Panel) is a circuit integration method, embedding the gate driver directly onto the glass substrate. This reduces the need for external ICs, enabling ultra-narrow bezels, thinner modules, and higher reliability in compact automotive applications like E-Mirror TFT designs.
In Truly’s new 9.2-inch automotive e-mirror module, the two technologies complement each other:
👉 a-Si TFT provides a stable, cost-effective foundation, while GIP integration simplifies the architecture, ensuring a slim and efficient module design.
Supporting innovations include local dimming for enhanced automotive contrast and optical bonding to improve outdoor visibility.
For higher-end applications, OLED is an alternative, but it faces durability challenges such as burn-in, as discussed in our OLED vs. LCD guide for automotive engineers.
Comparison: Traditional vs. GIP TFT E-Mirror Modules
| Feature | Traditional TFT Module | GIP TFT Module (Truly) |
|---|---|---|
| IC Count | Multiple ICs ⚠️ | Single IC ✅ |
| Bezel Size | Standard ❌ | Ultra-narrow ✅ |
| Power Efficiency | Moderate ⚠️ | Higher ✅ |
| Reliability in Automotive Use | Good ✅ | Excellent ✅ |
| Cost | Higher ❌ | Optimized ✅ |
This table shows why Truly’s GIP-enabled modules are particularly attractive for automakers seeking cost-effective slim displays.

FAQ: Automotive TFT Displays
Automakers prefer a-Si TFT because it offers proven stability, cost efficiency, and long production lifecycles. Unlike OLED, which can suffer from burn-in and high cost, a-Si TFT remains the most practical choice for mainstream vehicles.
Gate-in-Panel (GIP) integrates driver circuitry directly onto the glass substrate, reducing the need for additional ICs. This makes panels thinner, more reliable, and better suited for automotive display environments.
The G5 line allows Truly to scale production of advanced TFT modules while keeping costs competitive. This ensures a reliable supply of automotive-grade displays for global carmakers.
Not yet. While OLED offers superior contrast, it is prone to burn-in and costly to manufacture. MicroLED is promising, but still too expensive for large-scale automotive deployment. TFT LCD continues to dominate.
Truly’s automotive modules are used in infotainment screens, instrument clusters, rear-seat displays, and armrest-mounted auxiliary panels like the Range Rover’s 8-inch screen.
