Abstract
A voltage compensation circuit and A method thereof are provided. The voltage compensation circuit includes a power management chip, a feedback circuit, and a control circuit. A gate driving voltage (VGH) connects an input end of the control circuit, the input end of the control circuit connects to a first end of the fifth resistor (R5), and a second end of the fifth resistor (R5) connects to a forward input end of the voltage comparator, and first ends of the sixth resistor (R6) and the first capacitor (C1). A second end of the sixth resistor (R6) and a second end of the first capacitor (C1) are grounded, a backward input end of the voltage comparator connects to the reference voltage (VREF), an output end of the voltage comparator connects to a gate of the first FET (Q1). With such configuration, the display performance may be enhanced.
