1. A touch display comprising:

  • a substrate;

    a plurality of pixels, disposed at one side of the substrate, each of the plurality of pixels comprising;

    a transistor comprising;

    a semiconductor layer;

    a first electrode disposed on the semiconductor layer;

    a second electrode disposed on the semiconductor layer; and

    a gate electrode configured to control the transistor to be turned on and turned off;

    a pixel electrode electrically coupled to the second electrode;

    a first conducting layer disposed at a side of the transistor opposite to the substrate, electrically coupled to the first electrode, and configured to receive a touch driving signal; and

    a second conducting layer disposed at a side of the first conducting layer, insulated from the first conducting layer, and configured to drive a liquid crystal layer; and

    a plurality of third conducting layers disposed at a side of the pixels opposite to the substrate, each of the plurality of third conducting layers being configured to output a touch sensing signal in response to the plurality of touch driving signals received by the plurality of first conducting layers of the pixels.
