Features
The TW8817 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
for display on various TFT LCD panel types. An integrated timing
controller allows direct interface with digital LCD panels. Its
versatile analog inputs allow CVBS, S-video, signal to be
connected simultaneously.
Other features include: high quality adaptive 4H Comb Filter, 2D
de-interlacer and panoramic scaler, and multi-window
programmable 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. it
also includes cost saving feature like CCFL and LED controller,
charge pump booster and programmable panel offset control.
In addition, TW8817 has built-in microcontroller with external
SPI interface.
• Automatic color control and color killer
• Detection of level of copy protection according to Macrovision
standard
Built-in Micro-controller
• Support external SPI Interface
• Support I2C Master interface with GPIO
• Support Up to 4 MCU GPIO
• Support UART interface with GPIO
• Support IR or interrupt with GPIO
TFT Panel Support
• Supports a wide variety of Digital single pixel active matrix
TFT panels up to WXGA(1280x768), 100MHz
• Supports 3, 4, 6 bits per pixel format
On Screen Display
• Built-in OSD controller with integrated character ROM and
programmable RAM font.
• Multi-window OSD support with color pallet
• Support OSD overlay with alpha blending
