Abstract: A display device includes a display panel including a plurality of pixels, a timing controller which receives an image signal and a control signal and outputs transmission data, and a plurality of source driving circuits, each providing a data signal to a corresponding pixel among the plurality of pixels in response to the transmission data. Each of the source driving circuits applies a state information signal corresponding to an operation state to the timing controller, and the timing controller determines the operation state of the source driving circuits based on the state information signal, compresses the image signal when a source driving circuit of the source driving circuits is in an abnormal state to generate the transmission data, and applies the transmission data to a source driving circuit of the source driving circuits in a normal state.

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.
