LT768x (LT7681/LT7683/LT7686) is a high performance TFT LCD graphic controller IC series. It supports 16/18/24bits RGB panels with various resolutions ranging from 320x240 (QVGA) to 1280x1024 (SVGA). With built-in geometric drawing engine, LT768x supports drawing lines, curves, ellipse, triangle, rectangle, and much more. LT768x also has an embedded hardware graphics acceleration engine(BTE), which provides command-type graphic operations such as screen rotation, flipping, mirroring, PIP, and graphics blending etc. These functions can greatly enhance the display performance, and ease the processing burden on the MCU.
