More Information
Summary:The present invention provides a touch panel and a portable electronic device having the touch panel. The touch panel includes: multiple pixel circuits arranged in an array mode, wherein at least onefirst pixel circuit of each M*N pixel circuits includes: an active component, having a gate, a source cathode and a drain, the gate is electrically connected with the drain, the source cathode is electrically connected with a read wire; and a switch, one end is electrically connected with the second drain, the other end is electrically connected with the scanning wire. When the switch is turned on, the region of showing M*N pixel circuits constitution is the touched position of the touch panel, and M, N are positive integers. The touch panel of the invention accurately judges the touching position of the touch panel by users only by judging the dividing voltage value between the reference capacitor of the pixel configuring with a sensing region and the sensing capacitance whether changed or not, or only by judging
