Claim 0:
1. A capacitive touch screen device, comprising:
a plurality of gate lines, a plurality of data lines, and a plurality of common electrode lines, wherein the plurality of gate lines and the plurality of data lines perpendicularly intersect to form a plurality of pixel units arranged in an array; each of the plurality of common electrode lines is arranged in parallel with each of the plurality of gate lines and is arranged between one row of the plurality of pixel units and one of the plurality of common electrode lines, wherein the plurality of pixel units are divided into a plurality of touch detection regions, and an area of each of the plurality of touch detection regions is smaller than an area of a capacitive touch screen of the capacitive touch screen device touched by a finger;
a plurality of touch sensing units, wherein each of the plurality of touch sensing units is connected to one of the plurality of gate lines and one of the plurality of common electrode lines connected to any row of the plurality of pixel units in a corresponding touch detection region, and each of the touch sensing units is configured to detect charges in the corresponding touch detection regions; and
a plurality of read lines, wherein the plurality of read lines are arranged in parallel with the plurality of data lines, and each of the plurality of read lines is configured to connect to the plurality of touch sensing units located in a same column to convert the charges in each of the plurality of touch detection regions into a current and to output the current.
