Abstract: In a case when a camera is disposed under a display panel, a bounded part between a camera area and a surrounding area may have a brightness difference due to a difference in pixel disposition density. The present disclosure allows minimizing such a boundary effect by compensating for greyscale values of pixels in the bounded part.
