The embodiment of the invention provides a touch display screen and electronic equipment. The touch display screen comprises a liquid crystal layer, a touch electrode layer, a first electrode layer, an on-off control circuit, a display control circuit and a synchronous control circuit, wherein the touch electrode layer and the first electrode layer are oppositely arranged and located on the two sides of the liquid crystal layer, the touch electrode layer comprises a plurality of touch electrodes, the first electrode layer comprises a plurality of first electrodes, the on-off control circuit is electrically connected with at least one touch electrode, the display control circuit is electrically connected with the first electrodes, and the synchronous control circuit is electrically connected with the on-off control circuit. In the display stage, the display control circuit outputs first public voltage, the synchronous control circuit controls the on-off control circuit to output second public voltage, and the first public voltage is equal to the second public voltage. The touch display screen at least has the advantages of reducing display unevenness, avoiding ionic residues caused by bias voltage, improving display quality and reliability, simplifying the circuits, reducing the cost, and improving the product penetration rate on the premise that the touch characteristic is not affected.
