example 1

[0035] The first structure of the triboelectric generator is a three-layer structure, which includes: a first electrode layer, a first polymer insulation layer, and a second electrode layer stacked in sequence. Specifically, the first electrode layer is disposed on the first side surface of the first polymer insulating layer; and the second side surface of the first polymer insulating layer is disposed opposite to the second electrode layer. In the above structure, the first side surface of the first polymer insulating layer and the first electrode layer are relatively fixed, and the second side surface of the first polymer insulating layer and the second electrode layer are subjected to Contact friction when pressing or bending occurs and induces charges at the first electrode layer and the second electrode layer. Therefore, in this example, the two opposite surfaces of the first polymer insulating layer and the second electrode layer constitute the friction interface of the ...

Abstract

The invention discloses a display device, which can at least solve the problem that the display device in the prior art cannot use the self-power supply technology to drive the electronic paper display to achieve normal effects. The display device includes: an electronic paper display and a friction power supply for supplying power to the electronic paper display, wherein the friction power supply includes: a friction generator for converting mechanical energy into electrical energy when an external force is applied; The rebound limiting component is used to limit the rebound speed and / or rebound height of the friction generator after the external force disappears.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to a display device. Background technique [0002] With the rapid growth of demand for portable mobile devices and wearable display products, low-efficiency display devices have attracted widespread attention from the industry. At present, low-power display devices mainly include organic light-emitting diodes and electronic paper displays. Among them, organic light-emitting diodes must be continuously powered by an external power supply to display, and electronic paper displays can be powered off after a short period of power supply and continue to display the pattern before the power failure. Based on the above characteristics of the electronic paper display, it is obviously more suitable to use the electronic paper display to make a low-power display device. [0003] However, traditional electronic paper displays are mostly powered by a power module. Once the power of the power...
