  AL330 Digital LCD Display Controller SOC (EOL)

Functional Description

The AL330B is a highly integrated Display SOC, containing a 3-Ch + 10-bit ADC, 2D Video Decoder, Deinterlacer, Scaler, Microcontroller, OSD, and TCON. The AL330B can support small to medium Digital TFT-LCD Panels and small to medium AMOLED Display Devices.

The AL330B is a multi-channel analog preprocessing circuit, which includes source selection; anti-aliasing filter; ADC, ACC (Auto-Clamp Control) and AGC (Auto-Gain Control); CGC (Clock Generation Circuit); digital multi-standard decoder containing chrominance and luminance separation from an adaptive 2D comb filter; brightness, contrast, hue and saturation control circuit; programmable horizontal and vertical scaler; image and sharpness enhancement processing; On-Screen-Display; programmable TCON; and a digital RGB signal output etc.

  • In-Car TV/GPS/Navigation & Entertainment Display Systems
  • Video Door Phone, Baby Monitor, Digital
    Photo Frame etc.
  • Small to Medium Multimedia TFT-LCD,
    AMOLED Display Monitor
  • Portable TV/DTV (ATSC,DVB-T/-S)
