Abstract:
1. A display device with integrated touch screen, comprising: a panel including a plurality of electrodes, which are divided into n-numbered groups wherein ‘n’ is an integer equal to or greater than two; a data driver for converting RGB data inputted from a timing controller into a data voltage, and supplying the data voltage to data lines; a gate driver for sequentially supplying a gate signal to gate lines so as to apply the data voltage to pixels of the panel during a high logic period of a horizontal sync signal; a touch IC for supplying a touch scan signal to the plurality of electrodes every low logic period of the horizontal sync signal; and a plurality of switches being switched to apply the touch scan signal outputted from the touch IC to any one of the n-numbered groups, wherein the touch IC applies the touch scan signal, at least once, to each electrode in the plurality of electrodes during one frame, wherein the touch scan signal is sequentially supplied to the divided n-numbered groups of the plurality of electrodes, wherein in the panel of the display device, each of the pixels includes its own individual electrode of the plurality of electrodes together with a pixel electrode, and liquid crystal in each pixel is driven by the individual electrode together with the pixel electrode, wherein the plurality of electrodes are arranged in a grid including a plurality of rows and a plurality of columns, and wherein each row of the plurality of rows includes a plurality of electrodes and each column of the plurality of columns includes a plurality of electrodes.
