IN-CELL TOUCH SCREEN AND DRIVE METHOD THEREOF

摘要

An In-cell touch screen and a method for driving the same includes: concurrently providing a plurality of gate drive signals to the plurality of gate lines line by line and a plurality of touch drive signals to the plurality of drive lines line by line, collecting original touch signals from the plurality of sensing lines line by line; when collecting is performed on a sensing line and any gate line covered by the sensing line is supplied with a gate drive signal, defining the original touch signals collected from a sensing line as interference signals; and removing the interference signals from the original touch signals to obtain a valid touch signal.

1. A method for driving an In-cell touch screen, wherein the In-cell touch screen comprises an array substrate and a color film substrate disposed opposite to each other, the color film substrate comprises a plurality of drive lines and a plurality of sensing lines intersecting with the plurality of drive lines in an insulating way, the array substrate comprises a plurality of gate lines and a plurality of data lines intersecting with the plurality of gate lines in an insulating way, each of the sensing lines is parallel to the gate lines and covers multiple gate lines, the method comprising:
concurrently providing a plurality of gate drive signals to the plurality of gate lines line by line and a plurality of touch drive signals to the plurality of drive lines line by line; collecting original touch signals from the plurality of sensing lines line by line; wherein collecting is performed on a sensing line and any of the gate lines covered by the sensing line is supplied with a gate drive signal; defining the original touch signals collected from the sensing line as interference signals; and removing the interference signals from the original touch signals to obtain a valid touch signal.
