Abstract
A method for driving a color-sequential display suitable to reduce the color break-up phenomenon of the color-sequential display is disclosed. The method includes: dividing each sub-frame period into a data-writing period and a backlight turned-on period; within the data-writing period, transmitting a data of first color; during a first duration of the backlight turned-on period, turning on a first color backlight; during a second duration of the backlight turned-on period, turning on a second color backlight.
Claims12
A method for driving a color-sequential display, comprising:
- dividing each sub-frame period into a data-writing period and a backlight turned-on period;
- transmitting a data of a first color within the data-writing period;
- turning on a first color backlight during a first duration of the backlight turned-on period;
- and
- turning on a second color backlight during a second duration of the backlight turned-on period, wherein every three sub-frame periods are defined as a frame period, wherein:
- a data of red color is transmitted within the data-writing period of a first sub-frame period;
- a white backlight is turned on during the second duration of the backlight turned-on period;
- and
- a red backlight is turned on during the first duration of the backlight turned on period;
- wherein in the first sub-frame period, the second duration is prior to the first duration.
