Abstract: Provided is a display device having a touch sensor capable of improving touch sensitivity by removing the influence of display noise. The display device includes: a display panel including pixels connected to data lines and scan lines; a scan driver for supplying scan signals to the pixels through the scan lines; a data driver for receiving digital image data, converting the digital image data into an analog data signal, and supplying the analog data signal to the pixels through the data lines; a data variance calculator for calculating a variance in image data for each data channel by using the digital image data, and summing the variance in image data for each data channel to calculate an integrated data variance value; and a plurality of correction value calculators for calculating a touch correction value for each sensing channel by using the integrated data variance value.
Abstract: A display apparatus includes a first circuit configured to process a signal between a first top voltage and a first bottom voltage, a second circuit configured to process a signal between a second top voltage and a second bottom voltage, and a second circuit power source configured to receive a current provided by the first circuit and provide the second top voltage to the second circuit.
Abstract: A display device includes a substrate including a display area and a touch area overlapping the display area, a plurality of pixels disposed in the display area, and a plurality of touch cells disposed in the touch area and individually driven. At least some of the pixels are disposed on a same layer as at least some of the touch cells.
