FAQ

This 4.3-inch 800×480 optical bonded touch display combines a high-resolution TFT panel with a G+G capacitive touch structure and OCA optical bonding. With 720 cd/m² typical luminance, LVDS display interface, IIC touch interface, and 5-point touch support, it is designed for compact embedded equipment, industrial controls, vehicle electronics, and other applications requiring an integrated display and touch interface.

The cover glass is chemically strengthened with a minimum surface hardness of 7H, while the display supports an operating temperature range of -20°C to +70°C. The optical bonding structure helps reduce the air gap between the display and touch assembly for improved optical integration.

FAQ

1. What interfaces are used for the display and touch functions?
The TFT display uses an LVDS interface, while the capacitive touch panel uses an IIC interface. Both the TFT and touch system use a 3.3 V power supply.

2. Does this 4.3-inch touch display support multi-touch?
Yes. The capacitive touch panel supports up to 5 simultaneous touch points and is designed for finger operation.

3. What is the benefit of OCA optical bonding in this touch display?
OCA optical bonding reduces the air gap between the display and touch assembly, helping reduce internal reflections and improve optical integration. It also creates a more integrated display structure for applications with specific optical and mechanical requirements.

4. Is 720 cd/m² sufficient for outdoor applications?
The 720 cd/m² typical luminance provides improved visibility in bright ambient-light conditions, but it should not automatically be considered sunlight-readable for direct outdoor sunlight. Actual suitability depends on sunlight exposure, viewing conditions, enclosure design, and the optical requirements of the application.

5. Can this display operate in low-temperature environments?
Yes. The specified operating temperature range is -20°C to +70°C, with a storage temperature range of -30°C to +80°C.

6. Can FANNAL customize this 4.3-inch touch display?
Yes. FANNAL can evaluate customization of display size, cover glass, touch configuration, optical bonding, brightness, interfaces, and other mechanical or electrical parameters according to the application requirements.
