DESCRIPTION
WO320240G is a monochrome graphic LCD module made of 320x240 dot matrix format. This STN COG module is without built in controller IC. This COG module WO320240G is having the same outline dimension and VA size as TAB module WX320240G, but AA size is different. The WO320240G is an alternative item to replace WX320240G which TAB IC had been phased out. Comparing WO320240G (COG) to WX320240G (TAB), except the module structure is different; the outline dimension, VA size, interface, pin assignment, main electrical characteristics are the same, just AA size is a little different.
The supply voltage for logic of WO320240G is 3.0V to 3.6V, typical value 3.3V, 1/240 duty circle. This module can be operating at temperatures from -20℃ to +70℃; its storage temperatures range from -30℃ to +80℃. WO320240G is available in FSTN positive LCD and with White LED backlight; please contact us if you need different LCD type and LED combination.
