Title:
VOLTAGE CONTROL CIRCUIT, DISPLAY DEVICE, AND VOLTAGE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/127687
Kind Code:
A1
Abstract:
A voltage control circuit, a display device, and a voltage control method; the voltage control circuit adds an operational amplification module (101), a current detection module (102), a comparison module (103), and an increase module (104) to a power management integrated circuit, such that when the output voltage of an output terminal is insufficient due to the increase of the voltage drop on the wires caused by the increase of the output current in the circuit, the increase module (104) can be connected to the operational amplification module (101) in order to increase the amplification factor of the operational amplification module (101), and thereby increase the output voltage of the output terminal.
