132x32 COG LCD graphic modules

Winstar’s WO13232 is a monochrome graphic Chip on Glass (COG) LCDs with a 132x32 dot matrix format. These LCDs, with a built-in controller IC, provide an I2C interface, 6 o’clock viewing directions, 1/33 driving duty and a wide operating temperature.

The LCD matrix is a FSTN positive transflective LCD or as DFSTN negative (double film) transmissive LCD both with a white LED backlight. The supply voltage for logic is 2.7V to 3.3V, the typical value of 3V. These displays are available with 2 connecting options: FPC cable (WO13232A) or metal pins (WO13232B). Compared to the similar sized WG12232G these WO13232 modules have a higher resolution.
