Abstract:
An exemplary backlight control circuit for changing a brightness of a light source includes a coarse adjusting circuit and a fine adjusting circuit. The coarse adjusting circuit is configured to coarsely adjust a DC voltage according to one received coarse adjusting signal. The fine adjusting circuit is configured to finely adjust the DC voltage according to one received fine adjusting signal. A change of the DC voltage generated by the coarse adjusting circuit is greater than another change of the DC voltage generated by the fine adjusting circuit.
