Abstract:
A display panel driving apparatus includes a data processing circuit, a data driver, and a gate driver. The data processing circuit increases a first gamma value of input image data of which the gamma value is 0, according to a second gamma value of the input image data of which the second gamma value is not 0. The data driving part outputs a data signal based on the output image data to a data line. The gate driving part outputs a gate signal to a gate line.
