The GHLCD is an LCD that features the ability to display characters and graphics on three different layers. Unlike the CLCD, the GHLCD supports many different commands for easily drawing lines, circles, and boxes. There are also commands to copy, cut, and paste graphics, and a BMP downloader for downloading images to the GHLCD.

The GHB3224C model is a blue and white STN type LCD with a display area of 320 by 240 pixels. There are 3 layers. The first layer is for text and the other 2 layers can be used for graphics.

* GHB3224C Library is 99% compatible with Cutouch modules.

The text layer is a 40×15 grid as illustrated below. Each character size is 8 by 16 pixels.
