HD66841 - LCD Video Interface Controller

Download the HD66841 datasheet PDF. This datasheet also covers the HD66840 variant, as both devices belong to the same lcd video interface controller family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.
