Background

The cholesteric liquid crystal has a spiral arrangement structure by adding a light rotation agent into the nematic liquid crystal, and achieves different light penetration rates by showing two different liquid crystal molecule arrangement states of reflection and penetration under different voltage differences, thereby achieving the display effect. The principle is that under an external voltage, when a low voltage and a high voltage are applied respectively, a plane state can be converted into a focal conic state and a vertical state respectively: when in a planar state, incident light is reflected to develop color; in the focal conic state, most of incident light penetrates through a small part and is scattered; in the vertical state, the incident light is completely transmitted.

The planar state and the focal conic state are stable states, and when the voltage is turned off and disappears, the original state and the display picture are still maintained, and only when the state is changed into the other state and the display picture, the voltage is applied, which has the characteristics of low power consumption and memorability, and the cholesterol liquid crystal is the first choice of the electronic book.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: comprising a housing 1.

Wherein, a USB interface 2 is arranged on one side of the shell 1.

The USB interface 2 may enable the stored content to be exported via the USB interface 2, and meanwhile, the USB interface 2 may be used for charging.

The writing pen placing groove 3 is formed in one side of the surface of the shell 1, and a writing pen 4 is fixedly mounted inside the writing pen placing groove 3.
