Patent ID: 8773603

Claim:
A liquid crystal display (LCD) with an integrated touch screen panel, comprising: a first substrate having a plurality of pixels formed thereon, wherein each pixel of the plurality of pixels is provided with a thin film transistor and a pixel electrode; a second substrate facing the first substrate, the second substrate having a plurality of spaced common electrodes formed inside thereof, wherein the plurality of common electrodes is arranged in a first direction to correspond to the plurality of pixels and are not connected to one another; a plurality of sensing electrodes outside of the second substrate and arranged in a second direction intersecting the first direction; a liquid crystal layer between the first and the second substrates; and a common electrode driver that sequentially supplies a driving signal to the common electrodes and supplies a compensation signal having a phase opposite to the driving signal to the common electrodes, wherein: each common electrode is coupled to a different row of pixels, and the common electrode driver sequentially supplies driving signals to the common electrodes in a frame period, the common electrode driver supplying a driving signal with a compensation signal to each common electrode only once within the frame period.
