ABSTRACT:
A mixing type pixel driving method in an active display device includes generating a digital data for a selected pixel, first driving the selected pixel to be illuminated with a first illumination intensity, and second driving the selected pixel to be illuminated with a second illumination intensity in a second illumination interval. A relative ratio of the second illumination intensity to the first illumination intensity is changed according to the value of the digital data. The number of the converted bits by DAC is reduced. Therefore, the less bit DAC is adaptable for the mixing type pixel driving method and the layout area and the consumption current can be decreased.
