1、OVERVIEW
LCD driver interface has four kinds of interface, i.e. the conventional RGB-interface, I80 Interface and NTSC/PAL standard TV Encoder Interface and IT-R BT. 601 interface. The DISPLAY controller supports up to 5 overlay image windows. Overlay image windows support various color format, 16 level alpha blending, color key, x-y position control, soft scrolling, variable window size, and etc.The DISPLAY controller supports various color formats such as RGB (1BPP to 24 BPP), and YCbCr 4:4:4(only local bus).
LCD 驅動接口有四種接口，如傳統的RGB 接口，I80 接口，NTSC/PAL 標准TV 編碼器接口和IT-R BT.601 接口。顯示控制器支持5 層圖像窗口。覆蓋圖像窗口支持多種顏色格式、16 級alpha 混合、color key，橫縱坐標位置控制，軟動，可變窗口尺寸等等。顯示控制器支持各種顏色格式，如RGB（1BPPto24BPP），YcbCr4：4：4.
The DISPLAY controller is used to transfer the video data and to generate the necessary control signals such as,
RGB_VSYNC, RGB_HSYNC, RGB_VCLK, RGB_VDEN, and SYS_CS0(as well as the control signals). DISPLAY
controller has the data ports for video data, which are RGB_VD[23:0], SYS_VD[17:0], and TV_OUT as shown in
Figure 14-1.
顯示控制器用來轉換視頻數據，並產生需要的控制信號，如，RGB_VSYNC, RGB_HSYNC, RGB_VCLK,
RGB_VDEN 和SYS-CS0（作為控制信號）。顯示控制器有視頻數據端口，這些數據端口是RGB_VD[23:0]和
SYS_VD[17:0]，TV_OUT 如圖14-1 所示。
