Embodiment Construction

[0052] The touch screen of the embodiment of the present invention includes a piezoelectric sensing layer and a power collection unit; the piezoelectric sensing layer is used to sense an external force to generate an electrical signal, and transmit the electrical signal to the power collection unit; the power collection unit It is used for processing the electric signal and storing electric energy driven by the electric signal. Since the piezoelectric sensing layer in the embodiment of the present invention senses the external pressure, it converts the pressure signal into an electrical signal, and the power collection unit collects the electrical signal and stores electrical energy driven by the electrical signal, so that the portable electronic device When the power is low, the stored electric energy can be used to charge the battery.

[0053] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

Abstract

The invention relates to the technical field of liquid crystal display devices, in particular to a touch screen, a display panel, a display device and a method for storage electric energy. The touch screen, the display panel, the display device and the method are used for solving the problem that the electric quantity of portable electronic equipment is always insufficient in the use process. The touch screen comprises a piezoelectric induction layer and an electric quantity collecting unit. The piezoelectric induction layer is used for inducing external force to generate an electric signal and transmitting the electric signal to the electric quantity collecting unit. The electric quantity collecting unit is used for processing the electric signal and storing the electric energy under the driving of the electric signal. According to the touch screen, as the piezoelectric induction layer is deformed when sensing the external force, the electric signal is generated; the electric quantity collecting unit processes the electric signal, the required direct-current-amplification electric signal is obtained and collected, the electric energy is stored under the driving of the electric signal, the stored electric energy can be used for charging a battery, and therefore the problem that the electric quantity of the portable electronic equipment is always insufficient in the use process is solved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display devices, in particular to a touch screen, a display panel, a display device and a method for storing electric energy. Background technique [0002] At present, touch screens using touch technology are used in portable electronic devices such as smart phones and tablet computers. As the functions of portable electronic devices become more and more powerful, the frequency of use is also increasing. The capacity is relatively small, and it often encounters the problem of insufficient power. [0003] To sum up, due to the relatively small battery capacity of portable electronic devices, the problem of insufficient power often occurs during use. Contents of the invention [0004] The invention provides a touch screen, a display panel, a display device and a method for storing electric energy, which are used to solve the problem of insufficient electric power often occurring during the...
