Abstract

A liquid crystal display (LCD) with an integrated touch screen panel includes a plurality of pixels connected to a plurality of data lines and a plurality of gate lines, the gate lines being divided into a plurality of groups, a plurality of sensing electrodes, a plurality of common electrodes divided into a plurality of groups, a common electrode driver configured to simultaneously supply a driving signal to common electrodes within each group of the plurality of groups of the common electrodes, and to sequentially supply the driving signal to the plurality of groups of the common electrodes, and a gate driver configured to sequentially supply a gate signal to gate lines within each of the plurality of group of the gate lines.

Description

[0001] Korean Patent Application No. 10-2010-0106734 filed on October 29, 2010 and Korean Patent Application No. 10-2011-0037291 filed on April 21, 2011 with the Korean Intellectual Property Office are hereby incorporated by reference in their entirety . technical field [0002] Example embodiments relate to a liquid crystal display (LCD), and more particularly, to an LCD with an integrated interactive capacitive touch screen panel and a method of driving the same. Background technique [0003] The touch screen panel is an input device that allows a user's instruction to be input by selecting instruction content displayed on a screen of an image display or the like through a user's hand or an object. A touch screen panel may be formed in front of the image display to convert a touch position into an electrical signal. For example, when a user's hand or an object directly contacts the touch screen panel at the contact position, the instruction content selected at the contact...
