WF43VSIAEDNT0 is a 4.3-inch TFT LCD module with a Resistive Touch Panel (RTP). It is a color TFT LCD with a 480x272 resolution and 700 cd/m² brightness (typical value). This TFT model is built with an ST7282 driver IC, supporting 24-bit RGB interfaces. WF43VSIAEDNT0 is an alternative to replace WF43HSIAEDNTB, which adopted the CPT (Chunghwa Picture Tubes Ltd) EOL TFT panel.
The supply voltage for the logic (VCC) of WF43VSIAEDNT0 ranges from 3.1V to 3.5V, with a typical value of 3.3V. It features an anti-glare surface, a 12 o'clock view direction, 6 o'clock gray scale inversion, and a 16:9 aspect ratio. It can operate at temperatures from -20℃ to +70℃ and be stored at temperatures from -30℃ to +80℃.
