Abstract: The present disclosure discloses a backlight driving circuit and a display device. The backlight driving circuit includes a power supply chip, light-emitting diodes connected to the power supply chip, and a voltage protection sub-circuit connected to both the light-emitting diodes and the power supply chip. By adding the voltage protection sub-circuit, when a negative terminal voltage of the light-emitting diode is abnormal, the voltage protection sub-circuit will output a feedback signal to the power supply chip to stop the power supply chip from working, thereby improving reliability of the backlight driving circuit.

Abstract: Embodiments of the present disclosure provide a device and a method for adjusting brightness of a display device. In the method for adjusting brightness of the display device, a first voltage data is applied to the display device when a peak brightness condition is met, or a second voltage data is applied to the display device when the peak brightness condition is not met, enabling the first voltage data greater than the second voltage data to be applied to the display device when the peak brightness condition is met, thus increasing the brightness when the display device emits light to display an image to be displayed and improving contrast.
