Abstract

The invention discloses a display panel. The display panel comprises a substrate, a first coil, a first driving circuit, a piezoelectric film and a second coil, wherein the first coil is arranged on one side of the substrate; the first drive circuit is electrically connected with the first coil and used for responding to touch operation on the display panel to supply power to the first coil so that the first coil can generate a magnetic field; the piezoelectric film is arranged on one side of the substrate; the second coil is arranged on the piezoelectric film, the two ends of the second coilare electrically connected with the two sides of the piezoelectric film respectively, and the remaining part is insulated from the piezoelectric film and used for inducing a magnetic field to generatepotential difference on the two sides of the piezoelectric film, so that the piezoelectric film deforms, and the substrate vibrates. In this way, low-energy-consumption touch feedback can be achieved.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel. Background technique [0002] Currently, digital devices with touch screens such as smart phones, portable game consoles or computers have penetrated into people's daily life. The virtual keys on the touch screen have gradually replaced the physical keys of digital settings, making the operation of digital devices more convenient and efficient. However, users cannot obtain physical feedback when pressing physical buttons when using virtual buttons. In order to improve the operating experience when using the virtual keys, the touch feedback of the virtual keys is usually realized by means of vibration, sound effects, and the like. [0003] It is usually necessary to set additional components to realize the touch feedback of the virtual keys in the form of vibration / sound effects, such as linear motors, linear resonators, deflection motors or piezoelectric elements....
