LCD Flat Panel TV / PC Monitor Controller with Built-in
NTSC/PAL/SECAM Decoder, Analog RGB, DAC and
T-CON
TW8806
Techwells 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 up to 1280 by 768 with 1-
pixel/clock formats.
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 component and one analog
RGB simultaneously.
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 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 or high
resolution DTV 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
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 digital YCbCr
input for use with external ADCs for use as DTV monitor.
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.
