Touch panel and display device

A touch panel, comprising a plurality of light sensitive areas arranged in an array manner, wherein the touch panel comprises:

• a plurality of scanning lines disposed along a first direction;
• a plurality of data lines disposed along a second direction;
• a plurality of light sensitive circuits disposed in the light sensitive areas, wherein the light sensitive circuit comprises a light sensitive transistor, the light sensitive transistor comprises a substrate, a gate electrode, a gate insulation layer, an active layer, and a source/drain electrode layer, and the light sensitive transistor is configured to convert an optical signal to an electrical signal;
• and
• a touch circuit comprising a plurality of signal emitting electrodes disposed along the first direction, and a plurality of signal receiving electrodes disposed along the second direction;
• wherein the plurality of signal emitting electrodes form a plurality of signal emitting lines, and the plurality of signal receiving electrodes form a plurality of signal receiving lines;
• and
• wherein the light sensitive circuit comprises a readout line disposed along the second direction, the signal emitting line, the scanning lines, and the gate electrode are disposed on a same layer, and the signal receiving line, the readout line, and the source/drain electrode layer are disposed on a same layer.
