    摘要: In the backlight control circuit; a luminous flux sensing sub-circuit senses luminous flux of a display device, obtains and outputs a first control signal from a first control signal output terminal; a control sub-circuit includes N control units each including a first/second sub-unit; the first sub-unit connects or disconnects an output terminal of the second sub-unit and the backlight control signal output terminal under the control of the first control signal, the second sub-unit connects or disconnects a signal input terminal and the output terminal of the second sub-unit under the control of the second control signal; the N second control signal output terminals provide effective second control signals in a time division manner; conduction thresholds corresponding to the N first sub-units increase sequentially, and when a corresponding relationship between the first control signal and the conduction threshold is met, the first transistor is turned on.
