Introduction
In the quest to create immersive, edge-to-edge display experiences, narrow border design has become a defining feature across modern electronic devices. Whether in smart wearables, industrial terminals, automotive dashboards, or medical monitors, reducing bezel width not only enhances aesthetics but also maximizes usable screen area within limited enclosures.
At Truly, we push this boundary further through the combination of Narrow Border Design and Gate-in-Panel (GIP) technology — a powerful integration that minimizes external circuitry and frame size while maintaining signal stability and display performance.

What Is Narrow Border Design?
Narrow border refers to the ultra-thin frame around a display’s active area. Traditional TFT-LCD modules require a margin to accommodate gate driver ICs and signal routing pads, which inherently expand the bezel. However, by shrinking this margin, Truly enables more compact displays with a higher screen-to-body ratio — a key feature in devices where every millimeter counts.
| Feature | Traditional LCD | Narrow Border LCD |
|---|---|---|
| Bezel Width | ~2.5-3.5mm | <1.0mm (single side) |
| Screen-to-Body Ratio | 75-85% | Up to 92% |
| Design Aesthetic | Functional | Seamless, immersive |
GIP Technology: Integrating the Driver into the Panel
Gate-in-Panel (GIP) is a circuit integration technology that relocates the gate driver circuitry — traditionally placed on the PCB or FPC — directly into the TFT panel itself using high-voltage LSI embedded in the glass substrate. This approach eliminates the need for external gate ICs and helps achieve true borderless displays.
Key Benefits of GIP Integration:
- Reduces frame area by eliminating external IC mounting space
- Simplifies design with fewer components and shorter signal paths
- Improves EMI control by reducing signal interference from long interconnects
- Enables slimmer bezels while maintaining full electrical performance
Combined Advantage: Truly’s Narrow Border + GIP Integration
By combining narrow border design with GIP, Truly delivers compact, clean, and high-performance display modules for next-generation device makers.
| Advantage | Impact on Final Product |
|---|---|
| High screen-to-body ratio | More screen real estate for interaction and readability |
| Reduced module thickness | Easier integration into wearables or portable medical devices |
| Streamlined display interface | Fewer FPC layers and simplified layout |
| Improved durability | Smaller bezel = less mechanical vulnerability at display edge |
Applications: From Smart Bands to Industrial Touch Panels
1. Wearables & Fitness Bands
For smartwatches and fitness bands, a high screen-to-body ratio improves both usability and visual appeal. Narrow bezels make room for larger touch zones and reduce distraction from borders — especially critical in small 1.0–1.5” displays.
2. Industrial HMIs and Test Equipment
Narrow border GIP-integrated displays allow for compact but ruggedized human-machine interfaces (HMIs). GIP helps reduce parts count — critical for simplifying industrial module design and withstanding vibration or shock in harsh environments.
3. Automotive Display Clusters
Instrument clusters or center-stack displays in vehicles benefit from seamless transitions between display and dashboard materials. Truly’s narrow border + GIP architecture allows full-flat designs with minimal visual interruption.

FAQ: Narrow Border & GIP Technology
Narrow border displays increase the visible screen area without enlarging the device size, offering a more immersive and modern look, especially for small screens like wearables or handhelds.
GIP moves the gate driver IC into the glass substrate of the display itself, removing the need for external driver ICs and allowing designers to shrink the display’s bezel.
GIP requires advanced photolithography and integration techniques, but Truly has fully optimized its production process for high-yield and mass-scale manufacturing.
Yes. Truly provides custom shaping, ink printing, and cover lens lamination to match brand aesthetics or device contours.
No. In fact, Truly’s design reduces mechanical stress at display edges and improves robustness by minimizing fragile margins and component exposure.
