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.

Notes :

  1. VGH is TFT Gate operating voltage.
  2. VGL is TFT Gate operating voltage. The low voltage level of VGL signal must fluctuate with the same phase as Vcom.
  3. Vcom must be adjusted to optimize display quality, as Crosstalk and Contrast Ratio, etc..
  4. The value is just the reference value. The customer can optimize the setting value by the different D-IC.
