AL320C-EVB-A0 - Small-to-Medium TFT LCD/OLED Display EVB

 


Introduction

This evaluation product contains an LCD board with an AL320C, which is an Analog LCD Display Controller which is a combination of a multi-channel analog preprocessing circuit including source selection, anti-aliasing filter and ADC, ACC (Auto-Clamp Control and AGC (Auto-Gain Control), CGC (Clock Generatio Circuit), digital multi-standard decoder containing chrominance and luminance separation by an adaptive 2D comb filter, a brightness/contrast/hue/saturation control circuit, programmable horizontal and vertical scalar, image and sharpness enhancement processing, On-Screen-Display, programmable Tcon and 3-Channel DAC outpus, etc.

Other AL320C Applications

  • Head Mounted Display
  • Portable DVD Player
  • Car DVD/TV/GPS System
  • Portable TV/DTV
  • PMP (Portable Media Player)
  • Game station with LCD screen
