Embodiment 1

[0036] This embodiment provides a liquid crystal display panel, such as figure 1 As shown, it includes a first substrate 1 and a second substrate 2 oppositely arranged, and a cholesteric liquid crystal 3 arranged between the first substrate 1 and the second substrate 2, and the second substrate 2 is far away from the first substrate. One side of a substrate 1 is provided with an absorbing layer 4, wherein,

[0037] Apply pressure or heat to some positions of the first substrate 1 , and the corresponding cholesteric liquid crystals 3 at the positions can switch between the planar state and the focal conic state.

[0038] In the liquid crystal display panel of this embodiment, by applying pressure or heating to some positions of the first substrate 1, the corresponding cholesteric liquid crystal 3 at the position is switched between the planar state and the focal conic state, thereby realizing the writing of information, and erasure of specified information. The liquid crystal...

Embodiment 2

[0040] This embodiment provides a liquid crystal display panel, such as figure 2 As shown, it includes a first substrate 1 and a second substrate 2 oppositely arranged, and a cholesteric liquid crystal 3 arranged between the first substrate 1 and the second substrate 2, and the second substrate 2 is far away from the first substrate. One side of a substrate 1 is provided with an absorbing layer 4 made of a black material, wherein pressure or heat is applied to a part of the first substrate 1, and the corresponding cholesteric liquid crystal 3 at this position can be in a planar state or Switch between focal conic states. An alignment layer 5 is provided on the side of the first substrate 1 and the second substrate 2 close to the cholesteric liquid crystal 3 .

[0041] That is to say, the initial state of the liquid crystal display panel shows the color of the absorbing layer 4, where the material of the absorbing layer 4 is black, and the initial state of the liquid crystal ...

Embodiment 3

[0058] This embodiment provides a display component, such as Image 6 As shown, it includes the above-mentioned liquid crystal display panel and writing pen 8 , and the writing pen 8 includes: a pen holder 83 and a heat conducting end 81 and a pressure end 82 respectively arranged at two ends of the pen holder 83 .

[0059] Preferably, in a direction perpendicular to the pen holder 83 , the area of ​​the pressure end 82 is smaller than the area of ​​the heat conduction end 81 .

[0060] That is to say, a writing pen 8 used in conjunction with the liquid crystal display panel of Embodiment 2 is provided here. One end of the writing pen 8 can be heated, and the other end can apply pressure to the first substrate 1. Wherein, the area of ​​the pressure end 82 is smaller than that of the heat-conducting end 81, so the pressure of the pressure end 82 is slightly larger, and pressure is applied to the first substrate 1. More convenient, as easy as writing.

[0061] Preferably, a he...

Abstract

The invention provides a liquid crystal display panel and a display method and a display assembly thereof and belongs to the technical field of display. Through the liquid crystal display panel, the problem that an existing electronic tablet cannot achieve the effect of erasing specified content information at a specified position can be solved. According to the liquid crystal display panel, by exerting pressure on or heating a partial position of a first substrate, a cholesteric liquid crystal corresponding to the position is switched between a plane state and a focal conic state, and therefore write-in of information and erasing of the specified information are realized. According to the liquid crystal display panel, an upper electrode and a lower electrode are not needed, so that the material cost and the process cost are greatly lowered. The liquid crystal display panel is simple in structure and convenient to use and has a huge application prospect in the fields of tablets, intelligent cards and the like.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a liquid crystal display panel, a display method thereof, and a display component. Background technique [0002] The electronic writing board in the prior art includes: an upper substrate, a lower substrate arranged oppositely, and a liquid crystal sandwiched between the upper substrate and the lower substrate, wherein an upper electrode is provided on the inner side of the upper substrate, and a lower electrode is provided on the inner side of the lower substrate. [0003] The inventors have found at least the following problems in the prior art: the information erasing process of the electronic writing board in the prior art is realized by applying a certain high voltage to the upper electrode and the lower electrode. Since the upper electrode and the lower electrode of the writing board are electrodes on the whole surface, that is, the upper electrode and the lowe...
