Description

WF70A7TIAHLNB0 is a 7-inch TFT display with a resolution of 1024×600 pixels, featuring a capacitive touch screen. This 1024×600 display module supports an LVDS interface, and the capacitive touch panel is integrated with an ILI2511 driver IC, which supports USB interface (I2C available) and 10-point touch functionality.

The outline dimensions of the TFT are 164.80×99.8 mm, while those of the capacitive touch screen are 202×135.50 mm, with an active area size of 154.2144×85.92 mm. To align with market trends, the cover lens dimensions are designed to be larger than the TFT module.

This TFT model has a typical brightness of 450 cd/m2 and a supply voltage (DVDD) range from 3V to 3.6V. It features a glare surface panel, with a viewing direction at 12 o’clock and grayscale inversion at 6 o’clock, and has an aspect ratio of 16:9. Operating temperatures range from -20 to +70 ℃, with storage temperatures from -30 to +80 ℃.

This 7-inch 1024×600 display is suitable for various industrial devices, smart home applications, medical equipment, testing equipment, etc.
