Embodiment 1

[0059] This embodiment provides a specific liquid crystal lens equivalent to a Fresnel lens, so that the focal length of the glasses can be flexibly adjusted according to requirements, and a pair of glasses can be permanently worn.

[0060] figure 1 It is a sectional view of the liquid crystal lens in this embodiment, as figure 1 Shown is a horizontal cut view of the liquid crystal lens, the liquid crystal lens includes a first substrate 1 and a second substrate 2, the electrode unit includes a first electrode and a second electrode, at least either the first electrode or the second electrode includes a ring electrode; An electrode is located in the first substrate 1 and is arranged on the side facing the second substrate, a second electrode is located in the second substrate and is arranged on the side facing the first substrate 1, and the liquid crystal layer 3 is arranged on the first electrode and the second electrode. between the electrodes. Both the first substrate 1 a...

Embodiment 2

[0083] This embodiment provides a specific liquid crystal lens equivalent to a Fresnel lens, so that the focal length of the glasses can be flexibly adjusted according to requirements, and a pair of glasses can be permanently worn.

[0084] Such as Figure 10Shown is a cross-sectional view of the liquid crystal lens in this embodiment, the first electrode includes a first pixel electrode 14, and the first pixel electrode 14 is a ring electrode; the second electrode includes a second common electrode 22, and the second common electrode 22 is a planar electrode ; The electric field formed by the first pixel electrode 14 and the second common electrode 22 is a vertical electric field; the liquid crystal in the liquid crystal layer 3 is a blue phase liquid crystal.

[0085] A notable feature of blue-phase liquid crystals is that they are optically isotropic, such as Figure 11A Shown is the refractive index of the blue phase liquid crystal. When the incident light is emitted vert...

Embodiment 3

[0096] This embodiment provides liquid crystal glasses, which include the liquid crystal lens of any one of Embodiment 1 to Embodiment 2. Since the liquid crystal glasses can flexibly adjust the focal length of the glasses according to needs, they can be worn permanently and are suitable for applications in different scenarios.

[0097] When forming liquid crystal glasses, the plane direction of the substrate of the liquid crystal lens is the same as the plane of the glasses. Such as Figure 12 As shown, in the liquid crystal glasses, in addition to the liquid crystal lens 101, a sensing unit 102 and a control unit 103 are also included. The sensing unit 102 includes a plurality of distance sensors, and the distance sensors are connected to the control unit 103 for detecting the distance between the distance sensor and the control unit 103. The distance between the eyeballs of the human eye, and transmit the distance to the control unit 103; the control unit 103 is also used ...

Abstract

The invention belongs to the technical field of liquid crystal display, and particularly relates to a liquid crystal lens and liquid crystal glasses. The liquid crystal lens includes an electrode unit and a liquid crystal layer, and liquid crystal in the liquid crystal layer is equivalent to a Fresnel lens of which the focal length is adjustable under the effect of the electrode unit. According to the liquid crystal lens and the corresponding liquid crystal glasses, through the control over the electrode unit, liquid crystal in a liquid crystal box achieves effects equivalent to a concentric circle of the Fresnel lens, and the glasses are thin, light, small and exquisite in structure, can be matched with different vision changing situations of the human eyes, are used for solving various vision problems such as shortsightedness, farsightedness, astigmatism and presbyopia and become a kind of glasses capable of being worn permanently, so that people overcome troubles of changing glasses; further, even entertainment functions such as emotion hints can be added, and more abundant communication means are provided for people.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a liquid crystal lens and liquid crystal glasses. Background technique [0002] With the development of science and technology, modern people spend more and more time facing electronic screens every day, and their eyes are prone to fatigue, resulting in worsening vision. Many people are short-sighted, accompanied by astigmatism, and the degree of myopia may change in the annual physical examination review; with age, "presbyopia" may appear, and new glasses are needed to correct vision. According to the current glasses market, a pair of frames costs hundreds or even thousands of dollars, and it usually takes a few days to make glasses, grind the lenses, and remove the lenses. During the waiting process, people may have no glasses to wear because of old frames. "Touching in the dark", or running on the road because of having to go to the scene to auditio...
