Target Applications
Techwell’s TW8806 LCD display processor is a low cost high quality TFT
panel controller with an embedded NTSC/PAL/SECAM TV decoder. This
unique level of mixed signal integration enables the panel to be used as a
stand-alone LCD display for in car entertainment, portable DVD and
portable LCD TV applications. An integrated triple analog-to-digital
converter supports YPbPr/RGB component input and allows direct
connection to DVD and Navigation sources. In addition, flexible digital
inputs supports 24bit Digital RGB and 8/16/24-bit YCbCr inputs.
The TW8806 contains all the logic required to convert standard TV, DTV,
and PC monitor signals to the digital control and data signals required to
drive various TFT panel types. It supports TFT panel resolutions
The chip has nine analog inputs. This enables a number of input
combinations simultaneously. For example, the chip can accept up 4 CVBS
inputs simultaneously.The chip can also accept one CVBS, one S-Video, one
The integrated analog front-end contains three ADCs with three 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
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 or high resolution DTV formats to the output
panel resolution. An internal de-interlacing engine also allows interlaced
On Screen Display is supported through an on-chip OSD RAM for
maximum flexibility. A closed caption decoder is built in. The TW8806 also
accepts a 24 bit digital RGB input from external PanelLinkTM receiver or
ADCs for use as computer monitor. In addition, it accepts 8/16/24 bits

The TW8806 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 TW8806 core
operates at 1.8 V, the IO at 3.3 V and packaged in a 128-pin PQFP package.
