Claim 3:
4. The image sticking test method of claim 2, further comprising:
acquiring a third correspondence between a source-drain current of the preset drive transistor and time within a third preset time after the voltage of the preset drive transistor in the array substrate is switched from the first preset voltage to a fourth preset voltage;
acquiring a fourth correspondence between a source-drain current of the preset drive transistor and time within a fourth preset time after the voltage of the preset drive transistor is switched from the third preset voltage to the fourth preset voltage;
acquiring a second image sticking test curve of the array substrate according to the third correspondence, the fourth correspondence and the image sticking evaluation formula, wherein the second image sticking test curve is a correspondence between time and an image sticking evaluation value; and
acquiring a third image sticking test curve of the array substrate according to the first image sticking test curve and the second image sticking test curve;
wherein the fourth preset voltage is a voltage of the preset drive transistor when the array substrate is simulated to emit light under a condition of fourth grayscale, the fourth grayscale is between the first grayscale and the third grayscale, and the fourth grayscale is not equal to the second grayscale.
