Touch display and driving method thereof

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.
