The TW8827 is a low cost high quality TFT panel controller with
embedded NTSC/PAL/SECAM TV decoder. It incorporates all
the features required to create multi-purpose low cost LCD TV
systems in a single package. It contains all the circuits
required to adapt standard NTSC/PAL/SECAM analog TV input
signals as well as digital RGB signals for display on various TFT
LCD panel types. An integrated timing controller and triple
DACs allows direct interface with analog LCD panels. Its
versatile analog inputs allow CVBS, S-video and RGB signal to
be connected simultaneously.
Other features include: high quality adaptive 4H Comb Filter,
interlaced and progressive ITU601, interlaced ITU656 and
RGB656 inputs support, 2D de-interlacer and panaromic
scaler, and multi-window programmalbe OSD. It also
includes image enhancement functions such as black and
white stretch, 2D peaking, CTI, and favorite color
enhancement to further improve picture quality. To support
analog panel, it also includes cost saving feature like CCFL
and LED controller, charge pump booster and
programmable panel offset control. In addition, TW8827 has
built-in microcontroller with external SPI interface.
• Programmable white peak control for the Y or CVBS channel
• Software selectable analog inputs allows any of the
following combinations:
• 3 composite video
• 1 S-Video
