This abstract first appeared for US patent application 18816427 titled 'COMPENSATION CIRCUIT AND DISPLAY DEVICE

Original Abstract Submitted

A compensation circuit, including: a power management circuit and a switch circuit. The switch circuit is connected to a display panel and an operational amplifier circuit connected to the display panel. In case that a feedback voltage is greater than or equal to a target threshold, the switch circuit outputs a common voltage and an operating voltage to the operational amplifier circuit and stops outputting the common voltage to the display panel; and the operational amplifier circuit receives the common voltage and the operating voltage and outputs a compensation voltage to the display panel. In case that the feedback voltage is smaller than the target threshold, the switch circuit outputs the common voltage to the display panel and stops outputting the common voltage and the operating voltage to the operational amplifier circuit; and the operational amplifier circuit stops receiving the feedback voltage and stops outputting the compensation voltage.
