A driving method is provided. In the driving method, when there is the color crosstalk in the display screen, the target region and the to-be-calibrated region are first determined based on the gray scale value of each region of the to-be-displayed screen, so that by comparing the absolute value of the gray scale difference between the color pixel in the to-be-calibrated region and the target color pixel in the target region on the same data line with the preset threshold, whether the gray scale difference between the to-be-calibrated region and the target region affects the image quality can be determined.

An organic EL display device includes a first pixel circuit for displaying a first color. The first pixel circuit includes a large light emitting element, a small light emitting element, and a current control circuit that controls whether a current is supplied to the small light emitting element and the large light emitting element or not respectively, and the amount of the current to be supplied to at least one of the small light emitting element and the large light emitting element, according to a tone to be displayed by the first pixel circuit. The current control circuit supplies the current to the small light emitting element if the tone is equal to or smaller than a threshold value, and supplies the current to at least the large light emitting element if the tone is larger than the threshold value.

A liquid crystal display device in which pixels having a memory function are arranged includes: a display drive unit performing display driving by a driving method for obtaining halftone gray scales by setting plural frames as one cycle and temporarily changing gray scales of respective pixels within one cycle; and a pixel drive unit supplying a voltage having the same phase as, or the reverse phase to, a common voltage the polarity of which is inverted in a given cycle and applied to counter electrodes of liquid crystal capacitors to pixel electrodes of the liquid crystal capacitors. The pixel drive unit supplies an intermediate voltage between high- and low-voltage sides of the common voltage to the pixel electrodes of the liquid crystal capacitors at the time of transition from the supply of the voltage having the same phase to the supply of the voltage having reverse phase.
