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 display panel including first and second panel pads electrically connected to each other, a connection board including first and second connection board pads connected to the first and second panel pads, respectively, an output pad, and a driving circuit. The driving circuit includes a pull-up resistor connected between a first voltage terminal and a first node, and a comparator configured to compare a voltage at the first node with a reference voltage and to output a contact test signal corresponding to a comparison result to the output pad. The first connection board pad is electrically connected to the first node, and the second connection board pad is connected to a second voltage terminal.
