ED DESCRIPTION

[0038] Hereinafter, with reference to the drawings in the embodiments of the present disclosure, a clear and complete description of the schemes in the embodiments of the present disclosure will be provided. It should be apparent that the described embodiments are only a portion of the embodiments of the present disclosure, not all of them. Based on the embodiments of the present disclosure, all other embodiments that those skilled in the art obtain without making inventive contributions fall within the scope of protection of the present disclosure.

Embodiment 1

[0039] Please refer to FIG. 1, the first embodiment of this application provides a liquid crystal dimming eyeglasses. As shown in FIG. 2, the liquid crystal dimming eyeglasses include a frame 100, lenses 300, a liquid crystal film 400, and a circuit board 500. The lenses 300 are positioned within the frame 100, and the liquid crystal film 400 is attached to the lenses 300. The circuit board 500 is electrically connected to the liquid crystal film 400. In this structure, under the drive of the circuit board 500, the liquid crystals in the liquid crystal film 400 can deflect, thereby achieving dimming. In the first embodiment of this application, the liquid crystal dimming eyeglasses include two lenses 300 and two liquid crystal films 400. The two lenses 300 are spaced within the frame 100, and each lens 300 corresponds to a liquid crystal film 400, with each liquid crystal film 400 attached to the corresponding lens 300.

[0040] Specifically, as shown in FIGS. 3 to 5, the liquid crystal film 400 includes a first conductive layer 420, a second conductive layer 450, and a liquid crystal layer 440. The first conductive layer 420 and the second conductive layer 450 are oppositely arranged. The first conductive layer 420 has an inner ring portion 423, an outer ring portion 422, and an etched portion 421. The outer ring portion 422 partially surrounds the inner ring portion 423. The etched portion 421 is located between the inner ring portion 423 and the outer ring portion 422, insulating the inner ring portion 423 from the outer ring portion 422. The liquid crystal layer 440 is situated between the inner ring portion 423 and the second conductive layer 450. In this embodiment, the circuit board 500 is electrically connected to both the inner ring portion 423 and the second conductive layer 450. The circuit board 500 can control the deflection angle of the liquid crystals by adjusting the voltage difference between the inner ring portion 423 and the second conductive layer 450, thus achieving dimming.

[0041] In the liquid crystal dimming eyeglasses of this application, the first conductive layer 420 of the liquid crystal film 400 has an etched portion 421. The etched portion 421 divides the first conductive layer 420 into mutually insulated inner ring portion 423 and outer ring portion 422. When the cross-section of the liquid crystal film 400 gets contaminated with conductive powder, even if the outer ring portion 422 of the first conductive layer 420 becomes conductively connected to the second conductive layer 450 through the conductive powder, the insulation between the outer ring portion 422 and the inner ring portion 423 prevents the inner ring portion 423 from conducting with the second conductive layer 450, ensuring that the liquid crystal film 400 remains unaffected and can function normally.

[0042] It should be noted that the etched portion 421 can be an etching groove, which may, but is not limited to, be formed by laser etching.

[0043] Specifically, as shown in FIG. 3, the liquid crystal film 400 also includes a first flexible substrate layer 410 and a second flexible substrate layer 460. The first conductive layer 420 is located on one side of the first flexible substrate layer 410, which is on the side of the first conductive layer 420 that is away from the liquid crystal layer 440. The second conductive layer 450 is located on one side of the second flexible substrate layer 460, which is on the side of the second conductive layer 450 that is away from the liquid crystal layer 440.

[0044] Specifically, as shown in FIGS. 2 and 3, the liquid crystal dimming eyeglasses also include a wiring 600. The wiring 600 is at least partially positioned within the frame 100, and the circuit board 500 is electrically connected to both the inner ring portion 423 and the second conductive layer 450 through the wiring 600. The wiring 600 is a flexible circuit board, which has the advantages of small size and light weight, conducive to the miniaturization and lightweight design of the liquid crystal dimming eyeglasses, thus improving the user's wearing experience.

[0045] Specifically, as shown in FIGS. 4 and 5, the first conductive layer 420 has a first binding part 424, the etched portion 421 has an opening 4211, and the first binding part 424 is correspondingly arranged to the opening 4211 and can be electrically connected to the inner ring portion 423. The liquid crystal dimming eyeglasses also include a first conductive adhesive 700, which may be, but is not limited to, an anisotropic conductive adhesive, silver paste, or other conductive media. The wiring 600 is bound to the first binding part 424 through the first conductive adhesive 700. This structure ensures a stable electrical connection between the wiring 600 and the first binding part 424. In this embodiment, the second conductive layer 450 has a second binding part 451, and the liquid crystal dimming eyeglasses also include a second conductive adhesive 900, with the wiring 600 bound to the second binding part 451 through the second conductive adhesive 900.

[0046] It should be noted that, in FIGS. 4 and 5, the first conductive adhesive 700 covers the first binding part 424, with the dashed line representing the wiring 600, which covers the side of the first conductive adhesive 700 that is away from the first binding part 424.

[0047] Specifically, as shown in FIG. 5, the width W1 of the first conductive adhesive 700 is less than the width W2 of the opening 4211. This structure prevents the first conductive adhesive 700 from conducting between the outer ring portion 422 and the first binding part 424, thereby preventing a short circuit between the inner ring portion 423 and the outer ring portion 422.

[0048] Specifically, as shown in FIGS. 3 to 5, the liquid crystal film 400 also includes a sealing frame adhesive 430. The sealing frame adhesive 430 is located between the first conductive layer 420 and the second conductive layer 450 and is arranged around the liquid crystal layer 440. A part of the etched portion 421 corresponds to the sealing frame adhesive 430, and another part of the etched portion 421 extends to the outside of the frame adhesive 430. This structure, by having a part of the etched portion 421 correspond to the sealing frame adhesive 430 and another part of the etched portion 421 extending to the outside of the frame adhesive 430, increases the area of the inner ring portion 423, which is beneficial for improving the aperture ratio of the liquid crystal film 400.

[0049] Specifically, as shown in FIG. 2, the frame 100 includes a front frame 110 and a rear frame 120. The front frame 110 is assembled to the rear frame 120, with the lenses 300 clamped between the front frame 110 and the rear frame 120. Of course, according to the selection based on the actual situation and specific needs, other methods can also be used to fix the lenses 300 on the frame 100, which are not uniquely limited here.

[0050] Specifically, as shown in FIG. 2, the front frame 110 has a slot 111, and the rear frame 120 has a snap 121, with the snap 121 snapped and connected into the slot 111. This structure can reduce the assembly difficulty of the liquid crystal dimming eyeglasses and improve the assembly efficiency. Of course, according to the selection based on the actual situation and specific needs, it can also be that the rear frame 120 has a slot, and the front frame 110 has a snap, with the snap snapped and connected into the slot.

[0051] Specifically, as shown in FIG. 2, the liquid crystal dimming eyeglasses also include temples 200 and a battery 800. The temples 200 are hinged to the frame 100, and both the circuit board 500 and the battery 800 are located within the temples 200, with the battery 800 electrically connected to the circuit board 500. This structure can hide the circuit board 500 and the battery 800 inside the temples 200, thereby protecting the circuit board 500 and the battery 800.

[0052] Specifically, as shown in FIG. 2 and FIG. 6, at least one of the temples 200 includes a body 210 and a cover 220. The body 210 is hinged to the frame 100, and the cover 220 is assembled to the body 210. The body 210 and the cover 220 together enclose to form a housing cavity 230, with the circuit board 500 and the battery 800 located within the housing cavity 230.

Embodiment 2

[0053] Please refer to FIG. 1 as well as FIGS. 7 to 11, the second embodiment of this application provides a liquid crystal dimming eyeglasses, which mainly differs from the first embodiment in that: the liquid crystal dimming eyeglasses include one lens 300 and one liquid crystal film 400. The liquid crystal film 400 is attached to the lens 300, and the liquid crystal film 400 has two light-transmitting areas 470. These two light-transmitting areas 470 correspond respectively to the left and right eyes of the wearer.

[0054] It should be noted that the technical solutions of the various embodiments of this application can be combined with each other. However, such combinations must be based on what can be implemented by those skilled in the art. When the combination of technical solutions results in contradictions or impracticalities, such combinations should be considered non-existent and are not within the scope of protection sought by this application.
