HD66840 - LCD Video Interface Controller

Description

The HD66840/HD66841 LCD video interface controller (LVIC/LVIC-II) converts standard RGB video signals for CRT display into LCD data.

It enable a CRT display system to be replaced by an LCD system without any changes, and it also enables software originally intended for CRT display to control an LCD.

Features

  • Conversion of RGB video signals used for CRT display into LCD data.
  • Monochrome display data.
  • 8-level gray-scale data.
  • 8-color display data.
  • Selectable LVIC/LVIC-II control method.
  • Pin programming method.

HD66840/HD66841 LVIC/LVIC-II (LCD Video Interface Controller) Description The HD66840/HD66841 LCD video interface controller (LVIC/LVIC-II) converts standard RGB video signals for CRT display into LCD data. It enable a CRT display system to be replaced by an LCD system without any changes, and it also enables software originally intended for CRT display to control an LCD. Since the LVIC/LVIC-II can control TFT-type LCDs in addition to current TN-type or STN-type LCDs, it can support 8-color display as well as monochrome, 8-level gray-scale display. It can program screen size and can control a large-panel LCD of 720 × 512 dots. The LVIC-II thanks to a gray-scale palette, any 8levels can be selected from 13 gray-scale levels, depending on the LCD panel used.
