Abstract
The present invention provides a method for driving a backlight module of a liquid crystal display. The backlight module includes three light sources, a first light source, a second light source, and a third light source, that illuminate different color light respectively. The method includes sequentially turning on the three light sources, wherein the first light source and the second light source are turned on twice and the third light source is turned on once.
Claims8
A method for driving a backlight module of a liquid crystal display, wherein the backlight module includes a first light source, a second light source, and a third light source, each light source respectively illuminating different color light, the method comprising:
- turning on the three light sources sequentially, wherein the first light source and the second light source are turned on twice and the third light source is turned on once in a frame;
- wherein turning on the three light sources sequentially includes:
- turning on the first light source;
- turning on the second light source;
- turning on the third light source;
- turning on the second light source;
- and
- turning on the first light source, wherein the period for keeping the third light source in turning on state is shorter than twice the period for keeping the first light source in turning on state but longer than the period for keeping the first light source in turning on state.
A method for driving a backlight module of a liquid crystal display, wherein the backlight module includes a first light source, a second light source, and a third light source, each light source respectively illuminating different color light, the method comprising:
- turning on the three light sources sequentially, wherein the first light source and the second light source are turned on twice and the third light source is turned on once in a frame, wherein the time period for keeping the third light source in turning on state is less than twice the time period for keeping the first or second light source in turning on state but larger than the time period for keeping the first or second light source in turning on state.
