Patent ID: 8665234

Claim:
An in cell touch panel having a thin-film transistor substrate, an upper substrate, and a liquid crystal arranged between the two substrates, the in cell touch panel further comprising: a sensing signal processor having a plurality of pins; a plurality of readout lines, wherein one end of each readout line is connected to one of the pins and the other end is connected with at least a first sub-readout line and a second sub-readout line; a first series resistor and a second series resistor, wherein one ends of the first and second series resistors are respectively connected to different the sub-readout lines, and the other ends of the first and second series resistors are respectively connected to different a plurality of sensing lines which are arranged between the two substrates, wherein each of the sensing lines is connected to at least one corresponding sensing element in the thin-film transistor substrate, and the first series resistor and the second series resistor have different resistances with each other; and a match resistor whose one end being grounded and the other end being connected with a corresponding readout line, wherein the smallest resistance of the series resistors is greater than 5 times or more of the resistance of the sensing line, and the resistance of the match resistor is 2-10 times of the smallest resistance of the series resistors.
