摘要： A display apparatus is capable of improving a dynamic false contour. The display apparatus may control to change an order of a plurality of pulses of which widths are modulated for an emission time set within one frame, or divide pulses corresponding to the most significant bit (MSB) and the second significant bit (MSB-1) of image data among the pulses into two or more sub-pulses, and output the sub-pulses.
