Abstract

A low cost LCD device employing a high speed field sequential drive scheme. The liquid crystal display device comprises: a liquid crystal display array divided into a first area, a second area and a third area, in each of which are included a plurality of pel lines; a first device for performing an operation for sequentially writing first color data, selected from data provided for red, green and blue, along the plurality of pel lines in the first area, an operation for sequentially writing second color data, selected from data provided for red, green and blue, along the plurality of pel lines in the second area, and an operation for sequentially writing third color data, selected from data provided for red, green and blue, along the plurality of pel lines in the third area; a backlight device, which is divided into N backlight sections, with N being a multiple of three (3) and is equal to or greater than (6), and which selectively generates red light, green light or blue light, wherewith N/3 backlight sections illuminate the first area, N/3 backlight sections illuminate the second area and N/3 backlight sections illuminate the third area; and a second device for sequentially activating the N/3 backlight sections for the second area to generate second color light and sequentially displaying the second color data in the second area, and for sequentially activating the N/3 backlight sections for the third area to generate third color light and sequentially displaying the third color data in the third area.
