Abstract:
1. An in-cell touch panel, comprising: (a) a plurality of pixels spatially arranged in a matrix; (b) a plurality of scanning lines, each scanning line electrically coupled to a corresponding pixel row of the pixel matrix; (c) at least one touch sensing device electrically coupled between two neighboring scanning lines and associated with a pixel therebetween; and (d) at least one reverse amplification circuit comprising: wherein the at least one touch sensing device is configured such that when a touch occurs, it causes a gate voltage level of one of the first TFT and the second TFT to increase and the gate voltage level of the other to decrease; and wherein Vdh>Vdl, and wherein the at least one touch sensing device is characterized with a first charge sharing circuit and a second charge sharing circuit, each charge sharing circuit comprising:
