Techwell’s TW8807 LCD display processor is a low cost high quality TFT
panel controller with an embedded NTSC/PAL/SECAM TV decoder, scaler,
de-interlacer and timing controller. It is designed to support analog panels
used in video applications including portable TV, rear seat car display, and
portable DVD.
The TW8807 contains all the logic required to convert standard TV signals
to the digital control and data signals required to drive various TFT panel
types. It supports TFT panel resolutions up to WQVGA (480x234) with
1-pixel/clock formats.
The chip accepts CVBS (composite) analog input or S-video analog input
for use as a video monitor. Up to four physical CVBS inputs or one S-video
input can be connected.
The integrated analog front-end contains two ADCs with two clamping
circuits and one Automatic Gain Control (AGC) circuit to minimize external
component count. It employs a 4H, 5-line adaptive comb filter and
proprietary Y/C processing technologies to produce exceptionally high
quality pictures.
The chip's internal logic synchronizes the panel frame rate to the incoming
input frame rate. A high quality image-scaling engine is used to convert
the lower resolution formats to the output panel resolution. An internal de-
interlacing engine also allows interlaced video to be supported.
On Screen Display is supported through an on chip OSD RAM.
The TW8807 also supports TFT panel power sequencing, DPMS (VESATM
Display Power Management Signaling) signaling and power management.
The control interface is a 2-wire serial bus interface. The TW8807 core
operates at 1.8 V, the IO at 3.3 V and is packaged in a 64-pin PQFP package.
