wherein I(t)JND denotes an image sticking evaluation value of the array substrate at moment t after the voltage of the preset drive transistor is switched; I(t)A denotes a source-drain current of the preset drive transistor at the moment t after the voltage of the preset drive transistor is switched from the first preset voltage to the second preset voltage; I(t)B denotes a source-drain current of the preset drive transistor at the moment t after the voltage of the preset drive transistor is switched from the third preset voltage to the second preset voltage; I0A is a source-drain current of the preset drive transistor at the first preset voltage; and I0B is a source-drain current of the preset drive transistor at the third preset voltage.
