A flexible power generation power supply and its flexible display

Abstract

The invention discloses a flexible electricity generation power supply and a flexible display screen. The electricity generation power supply comprises a flexible substrate and multiple piezoelectric film electricity generation devices deposited on the flexible substrate, wherein each piezoelectric film electricity generation device comprises a lower electrode deposited on the flexible substrate, a flexible piezoelectric film deposited on the lower electrode, and an upper electrode deposited on the flexible piezoelectric film, and the upper electrode on each piezoelectric film electricity generation device is connected with the corresponding lower electrode in series. The flexible display screen comprises the flexible electricity generation power supply and multiple display units located on the flexible substrate, wherein the multiple display units are electrically connected with the flexible electricity generation power supply. The flexible electricity generation power supply solves the technical problem of flexible power supply of the flexible display screen, is matched with the flexible display screen, and can provide a usable power supply for the display screen in the absence of illumination.

Description

technical field [0001] The invention relates to the technical field of characteristic display, in particular to a flexible power generation power supply and a flexible display screen thereof. Background technique [0002] With the development of electronic technology, various display devices have been developed. In particular, display devices, such as televisions, personal computers, laptop computers, flat-screen mobile phones, and MP3 players, have been widely used to the extent that they are widely used. In order to satisfy users' needs for new functions, efforts have been made to develop new forms of display devices. A flexible display device is an example of a next generation display device. A flexible display device refers to a display device that can be deformed or can have its shape changed like paper. A flexible display device can be deformed by a force applied by a user, and thus can be used for various purposes. However, it is precisely because the flexible dis...

Problems solved by technology

However, it is precisely because the flexible display is light, thin, and flexible that the existing technology, such as the current power supply technology, is far from meeting the needs of the flexible display. Most of the existing speaker devices are based on the principle of electromagnetic relay, which is not conducive to the development of flexible display technology.

[0003] One of the existing technical solutions is to connect many tiny battery cells in series using some flexible structures to achieve the result of free movement, which can match the flexible display to a certain extent, but when the flexible display is twisted in any direction, This technology cannot adapt, and it will be more dangerous when the battery is twisted many times; there are also related reports that use flexible solar cell technology to provide power supply, but in the absence of light in the wild, the power storage capacity will be very large. There are very few, and the existing flexible solar cells under research and development are relatively thick, and the technology is not mature
