    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.

    Abstract: A display apparatus includes a display panel, a timing controller, a data driver, and a gate driver. The timing controller receives image data at a number of frames per second of a first level and generates a gate control signal and a data control signal. The timing controller includes an image converter that operates in film mode or normal mode when the input image data are moving image data, and that outputs film image data at a number of frames per second of second level lower than the first level during the film mode. The data driver applies a data voltage corresponding to the film image data to the display panel based on the data control signal. The gate driver applies a gate voltage to the display panel based on the gate control signal. The display panel operates at a frequency of the second level during the film mode.
