Abstract: A display device includes pixels, an auxiliary pixel, a controller, and an emission driver. The pixels are coupled to data lines and emission control lines. The auxiliary pixel is coupled to an auxiliary data line and auxiliary emission control lines. The controller is configured to measure an auxiliary current supplied from the auxiliary pixel through an auxiliary line, and to control a width of an emission start signal based on an accumulation amount of the auxiliary current. The emission driver is configured to, based on the emission start signal, supply emission control signals to the pixels and the auxiliary pixel through the emission control lines and the auxiliary emission control lines.

Abstract: A display device includes a display panel, a signal controller, sensing signal lines, and a touch sensor controller. The display panel includes pixels configured to display images, and touch sensor electrodes configured to sense a touch event. The touch sensor electrodes overlap a conductive layer. The signal controller is configured to generate signals to control the display of the images via the display panel. The sensing signal lines are respectively connected to the touch sensor electrodes. The touch sensor controller is configured to transmit a sensing input signal via the sensing signal lines, receive a sensing output signal via the sensing signal lines, and generate touch information based on reception of the sensing output signal. The touch sensor controller is configured to apply the same signal to the touch sensor electrodes and the conductive layer.
