Description
The WG12232C is a monochrome 122x32 graphic LCD display module with a PCB board, featuring an outline size of 84 x 44 mm and a viewing area size of 60 x 18 mm, delivering clear and concise graphic displays. This LCD module is built with the SBN1661G controller IC.
It supports a 6800 8-bit parallel interface and defaults to a 5V power supply, with an optional version of the negative voltage generator for 3V. The WG12232C type is available for external oscillation. If customers require internal oscillation of 2KHz, please choose the WG12232A type. If the customer requires support for Chinese fonts, please choose the WG12232L model series.
The WG12232C graphic LCD display module series comes with a PCB board, eliminating the need for customers to develop additional PCB boards themselves. Four screw holes are designed on the PCB to facilitate easy installation of the module on the application product. This 122x32 LCD module can operate at temperatures ranging from -20℃ to +70℃, with storage temperatures ranging from -30℃ to +80℃. Winstar provides various LED backlight combinations for the WG12232C module.
This graphic module is widely used in various industrial instruments and consumer products, such as measuring instruments, fuel dispensers, vending machines, coffee makers, audio systems, POS systems, household appliances, communication equipment, automation equipment, etc.
