The LPC247x microcontrollers have integrated LCD controllers. These microcontrollers support Super-Twisted Nematic (STN) and Thin-Film Transistor (TFT) graphic display panels up to 1024 x 768 pixels, from monochrome up to 24-bit true-color, and with hardware cursor support. This capability is ideal for point-of-sale, industrial, and medical/diagnostic applications. Further, the LCD controller supports Windows CE data formats.

Below are LPC247x-based design examples for a selection of common LCD daughter cards. The designs use an LPC247x Validation Board to carry LPC247x-related signals to the LCD daughter card. Each daughter card provides connectors to the universal LCD connector on the LPC247x Validation Board. Also included are LPC247x configuration codes (IAR EWARM), schematics, gerber files, and BOM's for each LCD module.
