Touch substrate, touch screen, and electronic device

A touch screen, comprising:

• a touch substrate, wherein the touch substrate comprises a substrate and a touch layer disposed on the substrate, and the touch layer comprises at least two electrode blocks arranged in a first direction and/or a second direction and sequentially connected to each other, and the electrode blocks comprises first electrodes and second electrodes;
• and
• wherein the first electrodes comprises at least two of the first electrodes arranged in a first direction and/or a second direction, the second electrodes comprises at least two of the second electrodes arranged in a first direction and/or a second direction, and the first electrodes and the second electrodes are insulated from each other and disposed crosswise in the electrode blocks,
• wherein in the first direction, two of the electrode blocks adjacent to each other are electrically connected to each other by at least one third metal bridge;
• in the second direction, two of the electrode blocks adjacent to each other are electrically connected to each other by at least one fourth metal bridge;
• and
• wherein the third metal bridge electrically connects the first electrodes in the two adjacent electrode blocks, and the fourth metal bridge connects the second electrodes in the two adjacent electrode blocks;
• or wherein the third metal bridge electrically connects the second electrodes in the two adjacent electrode blocks, and the fourth metal bridge connects the first electrodes in the two adjacent electrode blocks,
• wherein the third metal bridge or the fourth metal bridge is belonged to a same metal layer of the first electrode and the second electrode, and the third metal bridge and the fourth metal bridge are different metal layers;
• and
• the third metal bridge is belonged to the same metal layer of the first electrode and the second electrode, and at least one second insulating layer is disposed between the fourth metal bridge and the first electrode, and disposed between the fourth metal bridge and the second electrodes.
