Title:
DRIVE METHOD FOR DYNAMICALLY DRIVING FIELD SEQUENTIAL COLOR LCD
Document Type and Number:
WIPO Patent Application WO/2010/097018
Kind Code:
A1
Abstract:
A drive method for dynamically driving a field sequential color LCD is provided. In a passive matrix dynamically driving field sequential color LCD, a backlight source of which is at least provided with two or more than two colors, multiple fields constitute a frame, and every field comprises a scanning time, a non-scanning time and a light-off time of the backlight source of a COM. Every COM is scanned sequentially to drive all the liquid crystal pixels in the scanning time. The non-scanning time means the time in which all the liquid crystal pixels are not driven but the backlight source is persistently illuminated after the scanning time is over. The light-off time of the backlight source means the time in which all the liquid crystal pixels are not driven and the backlight source is turned off after the non-scanning time is over. The sum of the non-scanning time and the light-off time of the backlight source is between 1 and 10 milliseconds.
