A touch panel and an LED display screen comprises at least one touch-sensing layer, at least one pixel lamp spacer layer and at least one dielectric substrate layer, sequentially laminated. The touch-sensing layer includes a plurality of sensing units arranged at intervals and at least one grounding unit, wherein the sensing unit is not in contact with the ground unit; the ground unit is independently arranged or connected to any number of other ground units; the sensing unit is configured to sense a touch-control signal. The ground unit is configured to be grounded. A plurality of through-holes arranged at intervals are provided on the pixel lamp spacer layer, the through-hole is provided below the gap of the touch-sensing layer, and the through-holes are configured for receiving LED pixel lamps. The dielectric substrate layer is provided with several via holes.
