Description

WG12232E is a 122x32 graphic LCD module featuring a COB (Chip on Board) structure and a 2.2-inch diagonal size. This monochrome dot matrix graphic LCD is built with the SBN1661G controller IC or an equivalent controller. It supports a 6800 8-bit parallel interface and operates primarily at 5V power supply, with an optional negative voltage 3V drive mode.

This display includes an external 2kHz oscillator. For applications requiring an internal oscillator, please choose the WG12232J model, which shares the same specifications as WG12232E except for the oscillator type.

WG12232E offers multiple LED backlight color options and a choice of STN positive, STN negative, and FSTN LCD types to meet different optical and contrast requirements.
