Abstract
A compensation circuit and a display device. The compensation circuit includes a timing controller, a power management circuit, an operational amplifier circuit, and a delay circuit. The delay circuit is configured to prolong a time duration of the operational amplifier circuit in the operating state in a first stage, and the delay circuit controls the operational amplifier circuit to stop operation when the delay circuit is able to stably output a common voltage to the display panel. A time duration of outputting the common voltage to the display panel is prolonged in a second stage. When the operational amplifier circuit is in the operation state, the delay circuit stops outputting the common voltage to the display panel.
