Description
WO12864Q is a 128x64 COG monochrome Graphic LCD module. This LCD module is built in with ST7567 controller IC. It supports 6800 8-bit, 8080 8-bit parallel and4-line SPI interface, driving duty 1/65, 1/9 Bias. This COG LCD module can be operating at temperatures from -20℃ to +70℃; its storage temperatures range from -30℃ to +80℃. This LCD COG 128x64 display is very suitable for applications that demand more compact package displays. Please note the WO12864Q is the alternative model for WO12864D3 corresponding IC shortage or longer lead-time.
