Description

WF43VTIAEDNN0 is a color TFT LCD with a WQVGA resolution of 480×272 dots and a diagonal size of 4.3 inches. This TFT model is built-in with the ST7282 driver IC. WF43VTIAEDNN0 supports a 24-bit RGB interface and is available with optional Resistive Touch Screen (RTP) and Projected Capacitive Touch Screen (PCAP), as well as a high brightness option. WF43VTIAEDNN0 serves as an alternative item to replace WF43HTIAEDNNB, which adopted a CPT (Chunghwa Picture Tubes Ltd) TFT panel.

The supply voltage for logic (VCC) of WF43VTIAEDNN0 ranges from 3.1V to 3.5V, with a typical value of 3.3V. It features a glare surface panel, a view direction of 12 o’clock, grayscale inversion at 6 o’clock, and an aspect ratio of 16:9. The module has a contrast ratio of 500:1(typical value) and a brightness of 500 nits (typical value). It can operate at temperatures ranging from -20°C to +70°C and can be stored at temperatures from -30°C to +80°C.
