TW8826
LCD Flat Panel Processor with built-in MCU, NTSC/PAL/SECAM Decoder, T-CON
and Analog RGB Support
FN7765
Rev 1.00
August 9, 2011
General Description
The TW8826 is a highly integrated multi-purpose LCD display
solution for both analog panels. To reduce BOM cost, TW8826
integrates an 8-bit MCU and a CCFL or LED controller. Through
multiple input ports, TW8826 can directly display video and
graphic content from a variety of devices including TV Tuners,
DVD players, back-up cameras, DTV/DMB receivers and
navigation/GPS receivers.
Features
• Supports analog inputs including CVBS, S-Video, YPbPr &
RGB signals and digital inputs including 24 bit RGB &
8/16/24 bit YCbCr. Interlaced and progressive ITU 656
inputs are supported.
• Supports analog panels up to WQVGA resolutions
• Integrates cost saving features including LED controller,
CCFL controller, programmable panel offset control and on-
chip 8 bit 8051 MCU with SPI interface
• Embedded Image Enhancement
- Programmable CTI, hue, brightness, saturation, contrast
& sharpness control
- Black/White Stretch
- Programmable favorite color enhancement- up to three
colors
- Programmable Gamma Correction tables
