TW8800 LCD FLAT PANEL TV / PC MONITOR CONTROLLER
TECHWELL, INC.
Applications
Features
The TW8800 incorporates all the features required to
create multi-purpose LCD TV systems in a single package.
It contains all the circuits required to adapt standard
NTSC/PAL/SECAM analog TV input signals for display on
various TFT LCD panel types. With one external IC it
becomes both an LCD PC monitor controller and an HDTV
controller. Analog YPbPr and S-Video inputs allow direct
connection to analog component sources found on DVD
and HDTV decoders. Digital TTL YCbCr, and RGB inputs
allow digital TV, HDTV, or digital VGA monitor signals to be
input for display on the same LCD display panel.
Techwell's TW8800 is an enhanced version of the TW88
flat panel LCD TV/PC monitor controller. Primary
enhancements include: 4H Comb Filter, downscaling to
QVGA output resolution, digital progressive scan YCbCr
input including 422 and 444 input, one GAMMA lookup
table per color, and a new 48-bit YCbCr/RGB port. To
further facilitate the move to wide screen displays, the
TW8800 has the ability to show 4:3 images correctly
proportioned and centered in a 16:9 displays.
