1. A display device with integrated touch screen, comprising:
a display panel including a plurality of pixel electrodes; a touch screen including m number of electrodes which are formed to overlap with the plurality of pixel electrodes, wherein m is a multiple of n, and n is an integer equal to or greater than two, and wherein the m electrodes are divided into n number of electrode groups; a touch driver configured to generate a touch scan signal; and a display driver comprising:
a common voltage generator configured to generate the common voltage;a sync signal generator configured to generate a sync signal indicating the driving mode;a switching control signal generator configured to generate a control signal which allows the m electrodes to be simultaneously connected to the common voltage generator or allows the m electrodes to be connected to the touch driver sequentially for each of the electrode groups, according to the sync signal; andfirst switching units and second switching units configured to operate according to the sync signal and the control signal, the first switching units connected to the common voltage generator and to the touch driver, and the second switching units connected to the first switching units and the n electrode groups, the first switching units and the second switching units configured to apply the common voltage to the m electrodes or to apply the touch scan signal sequentially to the n electrode groups, depending on a driving mode of the display device. |
