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.
