Abstract
The present invention relates to a drive circuit of light source by color sequential method for generating a full-color image based on sequential switching between red, green and blue illuminations. The drive circuit of light source by color sequential method includes a color-sequential control circuit and a plurality of radiating areas coupled to multiple light units. The color-sequential control circuit is connected to those radiating areas to control the operation thereof by the color sequential method.
Claims6
A drive circuit of light source by color sequential method, comprising:
- a plurality of radiating areas;
- a plurality of light units coupled to said plurality of radiating areas, to provide required light to said plurality of radiating areas;
- a color sequential control circuit electrically connected to said plurality of radiating areas, to control the display of said plurality of radiating areas by color sequential method;
- and
- a charge recycle circuit connected to said plurality of radiating areas, to store voltage difference of second voltage subtracting first voltage and output a first voltage level when said plurality of light units turn from green or blue light units to red light units.
