摘要： A temperature compensation method for a display panel, a display panel, and an electronic device are disclosed. The display panel includes a pixel array, the pixel array includes a pixel unit, and the pixel unit includes a first voltage terminal and a second voltage terminal. The first voltage terminal is configured to receive a first power supply voltage, and the second voltage terminal is configured to receive a second power supply voltage. The pixel unit is configured to drive the light emitting element to emit light based on the first power supply voltage and the second power supply voltage that are received. The temperature compensation method for the display panel includes: setting a voltage difference between the second power supply voltage and the first power supply voltage as a first voltage difference, so as to enable a temperature of the display panel to rise, and setting the voltage difference between the second power supply voltage and the first power supply voltage as a second voltage difference after the temperature of the display panel rises. The first voltage difference is greater than the second voltage difference. The temperature compensation method for the display panel can effectively shorten the temperature rise time of the display panel, so that the temperature of the display panel reaches a stable temperature rapidly.
