Abstract
A display panel driving method and apparatus including a subfield generator converting input image data into subfield data; a determination unit detecting the number of inversions from the subfield data, determining whether an address power increases according to a calculation result, and outputting a determination result as a control signal; a storage unit delaying the input image data during one frame; and a gain controller applying a gain to the image data input from the storage unit, according to the number of inversions and in response to the control signal.
