Abstract
The present disclosure relates to a liquid crystal display (LCD) device, and particularly, to an in-cell touch type LCD device, and a method for driving capable of preventing deterioration of picture quality and enhancing touch sensitivity, by dividing a touch block in a spatial manner, not in a time manner. The in-cell touch type liquid crystal display (LCD) device, includes: an LCD panel including a first touch block and a second touch block having a plurality of gate lines and common lines; a gate driver for applying high-potential gate driving signals to the gate lines of the first touch block; a common voltage generator for supplying common voltages (Vcom) of first and second waveforms, to the common lines of the first and second touch blocks, respectively; and a touch detection circuit for detecting a touched position on the LCD panel through the second waveform common voltages.
