Description

WF70A8TYAHLNL0 is a 7-inch TFT LCD module featuring a Hover-Touch Capacitive Touch Panel, providing a seamless touchless user interface experience. The module boasts a resolution of 1024×600 pixels and is equipped with ST5021 and ST5651 driver ICs. It supports LVDS interface, with a contrast ratio of 800:1 (typical value) and brightness of 450 nits (typical value), delivering vibrant visuals in an aspect ratio of 16:9. The glare surface glass and normally black, transmissive LCD type enhance display clarity.

This TFT module utilizes IPS display technology, ensuring wider viewing angles of left: 85/ right: 85/ up: 85/ down: 85 degrees. Notably, it incorporates a projected capacitive touch panel (PCAP) with touchless interactive screen technology, supporting I2C interfaces and enabling 5-point touch functionality.
