Overview

Description

TW8811 is a high performance integrated LCD display processor designed for in-car display applications including navigation systems, in dash DVD players, rear-seat/ head-mount displays, and automotive TVs. The chip uses a single 27Mhz crystal, comes in a 208-pin LQFP package and is qualified for automotive applications including -40°C to +85°C temperatures and 1, 000 hours of reliability testing. TW8811 requires an external 64mbit SDRAM to support PIP and other advanced functions. Inputs include composite video, s-video, YPbPr, analog RGB, 24-bit digital RGB and 8/16/24 bit YCbCr. For composite video streams, a high quality 3D comb filter for NTSC and PAL with concurrent 3D noise reduction is integrated to reduce artifacts typically found in analog video signals. In addition to a 3D comb filter, a number of proprietary image processing algorithms are implemented in TW8811 to improve picture quality including a built in 2D-deinterlacing engine with low angle compensation, black/white stretch and color enhancement. TW8811 has a sophisticated PIP function that includes Picture in Picture (PIP) with variable sub-window size, picture over picture (POP), and multiple PIP. The TW8811 on-screen display can select 256 colors from 24-bit colors (16. 7 million colors) and is a graphic style OSD with a variety of functions including blinking, transparency, blending, and multi-window support. The TW8811 also supports external 18-bit OSDs with external alpha blending control.
