TW8811C
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.
