Flexible liquid crystal displays and handbags, bottle caps and smart cards containing them

Abstract

The invention discloses a liquid crystal display. The liquid crystal display comprises a nano power generation power supply, a liquid crystal driver and a flexible LCD screen, wherein the nano power generation power supply is connected with the liquid crystal driver and used for converting mechanical energy into electric energy and supplying power to the liquid crystal driver; the liquid crystal driver is connected with the flexible LCD screen, used for driving the flexible LCD screen through the electric energy supplied by the nano power generation power supply, and made of a flexible printed circuit board; the flexible LCD screen is used for conducting display according to the drive of the liquid crystal driver. The nano power generation power supply supplies power to the liquid crystal display and self-sufficient power supply can be achieved without an external power supply or battery equipment. Due to the fact that the nano power generation power supply is adopted and a circuit board of the liquid crystal driver is made of the flexible printed circuit board, the liquid crystal display can be made to be full flexible. The liquid crystal display can be applied to a handbag, a bottle cover, an intelligent card and the like.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a flexible liquid crystal display and a handbag, a bottle cap and a smart card containing the same. Background technique [0002] With the development of technology, liquid crystal displays are widely used in many fields such as small information terminals and large-scale projection equipment. However, the existing liquid crystal displays are generally powered by a traditional power source, for example, an external power source or a battery device provides power. However, such a power supply method has brought a lot of inconvenience to users: when an external power supply is used, the power cord needs to be connected with the LCD display, and the use of the power cord not only takes up space, but also limits the range of movement of the LCD display; When the battery power is exhausted, the battery has to be replaced, which is cumbersome to operate and can easily cause a po...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a flexible liquid crystal display, a handbag, a bottle cap and a smart card containing the same, to solve the problem that the liquid crystal display in the prior art must provide electric energy through an external power supply or battery equipment, cannot realize self-sufficient power supply, and due to the The limitations of the existing liquid crystal display cannot be made into a fully flexible liquid crystal display
