Abstract: A display device including: a display panel displaying an image based on first and second frames; a timing controller outputting a plurality of image signals for each of the first and second frames and outputting a test signal during a reset section; and a source driving chip outputting a plurality of data voltages corresponding to the image signals or a test voltage corresponding to the test signal. The reset section is arranged after the first frame and before the second frame, and the source driving chip blocks the data voltage in the second frame from being output to driving lines having an arrival time period equal to or less than a reference time period during the reset section, the arrival time period representing the amount of time taken to arrive at the test voltage from an initial voltage.

Abstract: A display device includes a first interconnection line, a first data driver, a second interconnection line, an electrostatic discharge (ESD) circuit, and a display panel. The first connection line transmits a data driving signal. The first data driver includes the first interconnection line and output a data signal based on the data driving signal. The second interconnection line passes through the first data driver and transmits a gate driving signal. The ESD) circuit in the first data driver and discharges static electricity transmitted through the second interconnection line. The first gate driver outputs a gate signal based on the gate driving signal transmitted through the second interconnection line. The display panel receives the data signal and the gate signal.
