5.30.1 Overview
The main purpose of Display Controller is used to display the video/image data to LCD device or
connect with external TV-encoder. The video/image data source may come from the image
sensor, JPEG decoder and the OSD pattern which have been stored in system memory
(SDRAM). The input data format of the display controller can be packet YUV422, packet YUV444,
packet RGB444, packet RGB565, packet RGB666, and packet RGB888. The OSD (On Screen
Display) function supports packet YUV422 and 8/16/24-bit direct-color mode. The LCD controller
supports both sync-type and MPU-type LCDM. This LCD Controller is a bus master and can
transfer display data from system memory (SDRAM) without CPU intervention.
