Description

The WF70A2SIAGDNL0 is a 7-inch TFT LCD module featuring a hover-touch capacitive touch panel with a resolution of 800×480 pixels. This model is built with ST5623D and ST5091D driver ICs, supporting a 24-bit RGB interface. It has a contrast ratio of 800:1 (typical value) and a high brightness of 700 nits (typical value). The display has an aspect ratio of 16:9, a view direction of 12 o’clock, a gray scale inversion direction of 6 o’clock, and glare surface glass.

This capacitive touch panel adopts hover-touch technology and includes the MXT874U, supporting the I2C interface. It supports multi-touch and single-touch hover functions. The advantages of hover-touch technology include:

No Direct Contact Required: Operate the screen without touching it, reducing fingerprints and smudges.
Increased Durability: Less screen wear and tear, extending the device’s lifespan.
Enhanced Flexibility: Suitable for environments where gloves or other barriers are used.
