TW8811是一款高性能的集成LCD显示处理器专为车载显示屏的应用,包括导航系统,车载DVD,后座/头戴显示器,以及汽车电视。该芯片采用单一27MHz晶体,采用的是208引脚LQFP封装,符合汽车应用,包括-40°C至+85°C的温度下进行1000小时可靠性测试。 TW8811需要一个外部SDRAM64Mbit的支持画中画等先进功能。

输入包括复合视频,S-视频,的YPbPr,模拟RGB,24位数字RGB和8/16/24位的YCbCr。对于复合视频流,一个高品质的3D梳状滤波器用于NTSC和PAL并发3D降噪整合,以减少通常出现在模拟视频信号的文物。

除了一个3D梳状滤波器,一些专有的图像处理算法在TW8811实现改善的图像质量,包括一个内置的2D-解交错发动机具有低角补偿,黑/白展宽和色彩增强。 TW8811具有复杂的PIP功能,包括画中画(PIP)具有可变的子窗口的大小,图像过画(POP),和多个画中画。

在TW8811屏上显示可以选择256种颜色,从24位颜色(1670万种颜色),并且是一个图形样式的OSD具有多种功能,包括闪烁,透明度,混合,和多窗口的支持。该TW8811还支持外部18位的OSD与外部alpha混合控制。
