Description

WG12232B is a monochrome graphic 122x32 LCD display module with a built-in SBN1661G controller IC supporting a 6800 8-bit parallel interface. The module includes FFC output pins. This LCD module supports a 5V power supply only, a 2KHz internal oscillator, and does not offer a 3V power supply version. WG12232B shares the same dimensions as WG12232M, with an outline size of 65.4 x 28.2 mm and a viewing area size of 54.8 x 19 mm, with an active area size of 48.76 x 15.32 mm. If you require a built-in Chinese character library, the WG12232M model is available as an alternative.

Please note that there is a gap in the middle of the glass display of this model, separating the display into upper and lower sections. If your product requires a continuous 122x32 dot matrix without this gap, please select the WG12232G model. Additionally, be aware that the FFC output pins of WG12232B and WG12232G differ. Please refer to the diagrams or contact our sales representatives for the complete specifications.

This module offers multiple LED backlight color options, and the LCD comes in STN positive, negative, and FSTN types. The operating temperature ranges from -20℃ to +70℃, and the storage temperature is between -30℃ to +80℃. All materials comply with RoHS environmental standards and EU REACH regulations.
