Abstract:
A temperature compensation circuit and method for a display panel and a display panel are provided. The display panel includes a control circuit, a driving circuit, a detection circuit and a pixel circuit; wherein the detection circuit is configured to obtain a current threshold voltage of a transistor of the pixel circuit, the control circuit obtains a current voltage difference between the current threshold voltage and an initial threshold voltage, obtains a current compensation gain matching the current voltage difference according to a predetermined related data of a voltage difference and a compensation gain, and controls the driving circuit to drive the pixel circuit by using the current compensation gain. By practice of the disclosure, the temperature compensation for a display panel could be achieved without the additional temperature sensor, so the service life of the display panel could be extended.
