Claim 7:
8. A reading method of the capacitive touch screen device in claim 2, comprising:
S1, detecting the charge in the corresponding touch detection region in real time through each of the plurality of touch sensing units;
S2, converting the charge into the current, outputting the current through the plurality of read lines, and converting the current into the output voltage through the plurality of read units, and reading it; and
S3, determining the touch position by determining the touch detection region according to at least one of the plurality of read lines, when the output voltage converted from the current output by at least one of the plurality of read lines exceeds a preset threshold.
