<p>The present invention provides a boost control circuit and a control method thereof, a boost circuit and a display device. A first triode and a second triode which are of different types are arranged in the boost control circuit, and the bases of the first triode and the second triode are connected with the driving voltage output pin of a boost control chip at a first node; the emitters of the first triode and the second triode are connected with the gate of at least one transistor at a second node; the collector of the first triode is connected with a first input power supply; and the collector of the second triode is connected with a second input power supply. Therefore, the intensity of control signals output by the boost control chip can be amplified, and the driving capability of the boost control chip over a switch transistor (MOS) is enhanced, so as to drive a high-power switch MOS by the boost control chip with limited driving capacity in a large-sized backlight scanning driving circuit, and guarantee the display quality of a liquid crystal panel.</p> |
