<p>The present invention relates to a liquid crystal display device, in particular, a liquid display device capable of alternatingly transmitting a pull-down signal generated from different pull-down transistors to a gate line in an image output time, and transmitting a pull-down signal by turning on all the different pull-down transistors in a touch detection time and a driving method thereof are provided. For the purpose, a driving method for a liquid crystal display device according to the present invention includes: a step which each of the stages connected to each gate line transmits a pull-up signal to the gate line formed on an in-cell touch panel in an image output time for a first frame period, and transmits a pull-down signal to the gate line by turning on a first pull-down transistor or a second pull-down transistor formed in the stage after the pull-up signal is outputted in the image output time; a step which a touch detection unit detects touch through a touch electrode formed on the in-cell touch panel while the each of the stages are transmitting a pull-down signal by turning on the first pull-down transistor and the second pull-down transistor in a touch detection time for the first frame period, and the each of the stages transmits the pull-up signal to the gate lines in order. [Reference numerals] (AA) First image outputting period;(BB) First touch sensing period;(CC) Second image outputting period;(DD) Second touch sensing period</p> |
