Abstract
A touch panel, the touch panel includes a control substrate, a touch layer and a piezoelectric layer that are stacked; the control substrate includes 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 piezo electric 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. The touch panel can realize the global tactile feedback function, and has a simple structure and has the advantages of thinner, lighter, lower driving voltage, and lower power consumption.
