A multicolor backlight modulation device receives the segment voltage signals and modulating a portion of the segment voltage signals to generate a common voltage signal and at least two synchronous color-separation backlight driving signals driving a backlight source to emitting different-color backlights. The common voltage signal cooperates with the segment voltage signals to form voltage differences which drive a mono-pixel to turn on or turn off in a time-division mode and allow different-color backlights to pass the mono-pixel at the same time. The time-division different-color backlights are accumulated by vision persistence to present a chromatic effect on the mono-pixel. The resultant colors can be intelligently varied via programming the segment voltage signals to achieve diversified multicolor effects. Therefore, the present invention can enable mono-pixels to present multicolor effect with a single-level display chip. | 03-04-2010 |
