Description
WF43WSYFEDHTV is a 4.3-inch High Brightness TFT LCD with a Resistive Touch Panel (RTP). The module features a control board with HDMI signal interface support (DVI only) and 40-pin GPIO connector, allowing developers to use it with Raspberry Pi (Raspberry Pi) effortlessly. Meanwhile, the 4 screw holes on the control board make it easy to mount. WF43WSYFEDHTV is built-in with controller TFP401, and it adopts an IPS panel providing wide viewing angles of Left: 80 / Right: 80 / Up: 80 / Down: 80 degrees (typical value). The display's brightness is 700 nits (typical value), and its resolution is 480×272 dots.
This TFT LCD uses an anti-glare glass surface with a 16:9 aspect ratio. It can operate at temperatures from -20℃ to +70℃, and its storage temperatures are from -30℃ to +80℃.
