Abstract

The invention discloses a display device and a display method. The display device comprises a direct-current friction nano-generator and a display structure, the direct-current friction nano-generatorcan generate a direct-current electric signal under the action of an external force, namely the mechanical energy in an external environment is converted into the electric energy, so that the electric energy outputted by the direct-current friction nano-generator can supply power to the display structure, the power supply to the display structure can be realized without setting a power supply, and the passive self-driving is realized. The direct-current friction nanometer generator is adopted and outputs the direct-current electric signals, so that the display device does not need to be provided with a rectifier and other structures, the display structure can be effectively driven to display only through the direct-current friction nanometer generator, the structure of the display deviceis further simplified, and the manufacturing cost of the display device is reduced. Moreover, the display device can be designed to be light in weight and portable, so that the requirements of variousapplication scenes are met, and the application field of the display device is widened.

Description

technical field [0001] The invention relates to the technical field of electronic devices, in particular to a display device and a display method. Background technique [0002] As a new type of emissive display, electronic paper display has great application prospects in various fields because of its advantages such as low power consumption and high contrast. However, since the electronic paper display needs a power supply to provide electric energy for displaying, the development of the electronic paper display in terms of light weight and portability is limited. [0003] Then, how to realize the light weight and portable design of the electronic paper display is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] Embodiments of the present invention provide a display device and a display method for realizing the light weight and portable design of the electronic paper display. [0005] In the first aspect, an embodi...
