Abstract
A display device includes blocks each including two or more pixels commonly coupled to a first power line, and a first power voltage controller for determining a margin value of a first power voltage supplied to the first power line, based on load values of the blocks. The first power voltage controller determines the load values based on grayscale values of the pixels included in each of the blocks. The magnitude of the first power voltage is determined to become smaller as the margin value becomes larger. The margin value includes a first margin value. The first power voltage controller determines the first margin value according to a degree of distribution of load values of first blocks arranged in a first direction among the blocks.
