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.

Claim (Index 2):
A display panel, comprising:\n a control circuit, a driving circuit, a detection circuit and a pixel circuit; wherein the control circuit, the driving circuit and the pixel circuit are sequentially electrically coupled, the detection circuit respectively electrically couple to the control circuit and the pixel circuit 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 to compensate an impact of temperature variation on the pixel circuit.
