Low cost, highly integrated LCD controller for digital LCD panels

Product Status: Mass Production

OVERVIEW

The TW8817 is a highly integrated low cost TFT flat panel controller supporting digital panels. To reduce BOM cost, TW8817 integrates a SECAM/NTSC/PAL video decoder supporting CVBS & S-Video inputs, an 8-bit MCU, a CCFL controller and a LED controller. The TW8817 integrates a high quality NTSC/PAL/SECAM 2D video decoder and a 2D De-interlacer/Scaler.

KEY FEATURES

  • Supports analog inputs including CVBS & S-Video signals
  • Supports digital panel up to SVGA resolution
  • Integrated 8-bit 8051 MCU, CCFL and LED controller
  • Built-in 8 color font based OSD with ~200 ROM & 75 RAM fonts. Supports Multi-color fonts by combining 3 single color fonts
  • Embedded Image Enhancement
  • Programmable CTI, hue, brightness, saturation, contrast & sharpness control
  • Black/White Stretch
  • Programmable favorite color enhancement- up to three colors (Skin, Grass & Sky)
  • Programmable Gamma Correction table
