Summary: | A display device includes a display panel including pixels, a luminance controller that divides the display panel into blocks based on coordinate information, calculates a block reference current based on a block current sensed in each of the blocks when reference images are sequentially displayed on the blocks, calculates a target current based on the block reference current and a block load of each of the blocks based on input image data, and calculates a scaling factor based on the target current and a sensing current sensed in each of the blocks when an input image corresponding to the input image data is displayed on the display panel, and a data driver that generates a data voltage corresponding to the input image data and supplies the data voltage to the pixels by adjusting a voltage level of the data voltage based on the scaling factor. |
