Description
WO320240F is a COG graphic LCD module made of resolution 320x240 pixels. WO320240F model is built-in with 2 chips of UCi7701 driver IC and 1 chip of UCi7702 driver IC; 1/240 driving duty. Furthermore, it is also built-in with negative voltage generator and temperature compensation available as optional.
WO320240F model supports 3.3V and 5V power supply voltage. This module can be operated at temperatures from -20°C to +70°C; its storage temperatures range from -30°C to +80°C. WO320240F is available in white background color and black content; the LCD matrix is a positive FSTN with transflective polarizer. Welcome to contact us if you need different LCD type and LED combination. Please note WEO320240F is the alternative of WO320240G since the original IC has been EOL.
