Project Description
VIS070TN92 is a 7 inch TFT LCD Display Screen Module model that adopts TN type LCD with 800*480 resolution. CTP (Capacity Touch Panel) and RTP(Resistive Touch Panel) can be added according to user requirements.
Among medium-sized LCDs, 7 inch LCD screen is the most shipped and has one of the most extended life cycles. There are still many more than ten years of 7-inch serial models active in the LCD market.
Based on the substantial and long-term shipments of 7 inch TFT display, we can absolutely guarantee a stable supply of this 7″ LCD screen module throughout the life cycle of customer’s products.
Based on the panel’s high-cost performance, High stability and excellent storage and operating temperature range, this 7 inch TFT display module can be widely used in smart homes, pos machines, industrial instruments (meters), and small medical equipment and other products.
FPCA pin defines & shape alignment, polarizer material, and backlight brightness can all be adjusted according to your needs.
We also provide 7 “IPS type LCD module and 7” LCD panel with 1024*600 resolution products for your choice. If interested, please contact us for more information.
Other 7 inch TFT LCD Display Screen Module(LCM) models that can be replaced by VIS070TN92 are AT070TN92, AT070TN94, AT070TN83, G070VVN01.2, etc.

6. Electrical Characteristics 6.1 TFT LCD Module
| Parameter | Symbol | Value | Unit | Remarks |
| Digital supply voltage | VDD | 3.3(3.0-3.6) | V | |
| Analog supply voltage | AVDD | 10.3 | V | |
| TFT Gate ON Voltage | VGH | 18 | V | |
| TFT Gate OFF Voltage | VGL | -8.0 | V | |
| TFT Common Electrode Voltage | VCOM | 3.38(3.2-3.5) | V |
Notes :
- VGH is TFT Gate operating voltage.
- VGL is TFT Gate operating voltage. The low voltage level of VGL signal must fluctuate with the same phase as Vcom.
- Vcom must be adjusted to optimize display quality, as Crosstalk and Contrast Ratio, etc..
- The value is just the reference value. The customer can optimize the setting value by the different D-IC.
