Abstract
A display device and a grayscale compensation method thereof. The display device includes a data conversion circuit, a voltage drop estimation circuit, and a compensation circuit. The data conversion circuit converts a plurality of original grayscale data of a target pixel block into current data. The voltage drop estimation circuit converts the current data into transmission line voltage drop information of the target pixel block. The compensation circuit converts the transmission line voltage drop information into at least one pixel compensation value of the target pixel block, and uses the at least one pixel compensation value to compensate the original grayscale data of the target pixel block, so as to generate a plurality of compensated grayscale data of the target pixel block.
