<p>PURPOSE: A power control circuit, a power control method, and a display device are provided to increase the usage efficiency of a power control circuit by operating an OVP(Over Voltage Protection) circuit through one control circuit. CONSTITUTION: An LED control circuit(10) is connected to a power control circuit(20) and includes an OVP input and output terminal(P1). At least one switch unit(21) is connected to one end of the OVP input and output terminal and includes a resistive device(12) and a switch device. A signal processing unit outputs a control signal to the switch unit. The switch device is operated by the control signal to set a voltage level of the OVP circuit.</p> |
