Abstract: A driving device of a display panel includes a timing controller which converts a first image data to a second image data, and generates control signals that control a driving timing of the second image data, a gamma data provider which determines a driving frequency of the second image data based on the number of a counting signal output during an active period and a blank period of a vertical synchronized signal, and outputs one of gamma data sets based on the driving frequency, a data driver which generates a data signal corresponding to the second image data based on the one of the gamma data set, and provides the data signal to a data line of a display panel based on the control signals, and a gate driver which provides the gate signal to a gate line of the display panel based on the control signals.
