Abstract:
1. A method of driving a display apparatus including a plurality of unit light-emitting blocks, the method comprising: determining a luminance representative value of a unit light-emitting block from pixel data of a plurality of image blocks corresponding to the unit light-emitting block including a plurality of light sources; calculating a luminance compensation value for the unit light-emitting block, the luminance compensation value calculated from the luminance representative value; correcting pixel data of pixels disposed in a central area of the unit light-emitting block and pixel data of pixels disposed in a boundary area of the unit light-emitting block, based on the luminance compensation value; and providing a driving signal to the unit light-emitting block based on the luminance compensation value; wherein, when the luminance representative value forms a ratio with respect to a maximum luminance representative value of luminance representative values of adjacent unit light-emitting blocks, where the ratio for each respective unit light-emitting block is less than a predetermined compensation ratio, the luminance compensation value is calculated, where the luminance compensation value forms a ratio with respect to the maximum luminance representative value, the ratio of the luminance compensation value being equal to or greater than the predetermined compensation ratio.
