Touch panel

A touch panel, comprising a control substrate, a touch layer and a piezoelectric layer that are stacked,

• wherein the control substrate comprises a first substrate and a control circuit layer arranged on the first substrate, and the touch layer and the piezoelectric layer are located on the control substrate,
• the control circuit layer comprises a control circuit, and the control circuit is electrically connected with the touch layer and the piezoelectric layer respectively, and is configured to apply electrical signals to the touch layer and the piezoelectric layer and/or receive electrical signals from the touch layer and the piezoelectric layer respectively,
• wherein the touch panel further comprises a second substrate, wherein the touch layer and the piezoelectric layer are arranged on the second substrate, and
• the second substrate, the touch layer and the piezoelectric layer are arranged as a whole on a side of the control circuit layer away from the first substrate,
• wherein the touch panel further comprises at least one spacer arranged between the second substrate and the control substrate, to space the second substrate and the control substrate,
• wherein the touch panel further comprises at least one pressure sensor sensitive element arranged between the second substrate and the control substrate, wherein the at least one pressure sensor sensitive element is electrically connected with the control circuit, and
• in a direction perpendicular to the second substrate, a height of the at least one pressure sensor sensitive element is lower than a height of the at least one spacer,
• wherein the touch layer and the piezoelectric layer are respectively arranged on a same side of the second substrate, and
• the touch panel further comprises an electromagnetic shielding layer arranged between the touch layer and the piezoelectric layer,
• the electromagnetic shielding layer is a conductive layer and is grounded or be applied with a fixed low-level voltage,
• an interval insulating layer is arranged between the electromagnetic shielding layer and the piezoelectric layer.
