Abstract
A current control circuit, which includes an energy storage unit, a first switch unit, and a pulse width modulation unit. A first end of the energy storage unit is connected to a first preset voltage terminal V1 through the first switch unit, the first end of the energy storage unit is further connected to a first signal output of the level conversion chip so as to input a high level signal. A second end of the energy storage unit is connected to other signal outputs of the level conversion chip. The pulse width modulation unit is configured to modulate a duty cycle of the first switch unit. The current control circuit can accurately control the magnitude of the current in the display panel after a power-off instruction is received by the display device, thereby protecting the display panel.
