Problems solved by technology

The disadvantage of this invention is that if the strip-shaped decorative layer is too thin, it will be difficult to align with the stitching seam to achieve light shading; if it is too thick, the stitching seam will be too obvious, which will affect the appearance of the dimming window
Since the connection relationship between the liquid crystal dimming film and the upper and lower transparent substrates is not considered, the strength of the upper and lower transparent substrates cannot be used to strengthen the strength of the liquid crystal dimming film
[0011] Chinese patent ZL201020101592.3 mentioned in the background technology that two pieces of dimming films are combined by hot-melting in the prior art, but there will be a certain size of glue-opening area at the splicing place.
[0016] The above-mentioned integrated structure of the dimming window has a single dimming mode, which cannot achieve various practical dimming effects such as pulling from the center to both sides or from one side to the other like curtains

Embodiment 1

[0051] Such as figure 1 , 2 As shown, the dimming window in which the liquid crystal dimming strips are arranged in a grid shape includes a liquid crystal dimming strip 1 , an adhesive strip 2 and two upper and lower transparent substrates 3 and 4 . The upper and lower transparent substrates 3 and 4 are plexiglass plates, and polycarbonate plates and glass plates can also be used; the adhesive strip 2 is an acrylic monomer or prepolymer injected into the adjacent liquid crystal dimming strip 1 After the gap between them is formed by polymerization and curing under ultraviolet light; the lead-out electrodes of the liquid crystal dimming strip 1 are drawn out in any known manner.

[0052] The above structure can be realized by the following steps:

[0053] Step 1): Use laser cutting or mechanical cutting to cut the commercial liquid crystal dimming film into strips along the length direction, and leave the positions of electrodes on the short sides of the two ends respectively...

Embodiment 2

[0060] Such as figure 1 , 2 As shown, the dimming window in which the liquid crystal dimming strips are arranged in a grid shape includes a liquid crystal dimming strip 1 , an adhesive strip 2 and two upper and lower transparent substrates 3 and 4 . The upper and lower transparent substrates 3 and 4 are both plexiglass plates, polycarbonate plates, or glass plates; the adhesive strip 2 is a hot-melt film material that flows to the liquid crystal dimming strip 1 after heating and melting The gap between the positions is formed after cooling.

[0061] The specific manufacturing steps are given below:

[0062] Step i): Use laser cutting or mechanical cutting to cut the commercial liquid crystal dimming film into strips along the length direction, leave the positions of electrodes on the short sides of both ends, and lead out the metal wires with the existing technology, according to In the existing known technology, the electrodes are respectively bonded and fixed with conduct...

Embodiment 3

[0069] Such as image 3 shown with the removed figure 1 The top view of the structure after the upper and lower transparent substrates 3 and 4 in . The strip-shaped liquid crystal dimming strips 1 surrounded by polygons and arcs are arranged in a grid structure; each liquid crystal dimming strip 1 satisfies the condition that the ratio of its length to the average width is greater than 10:1; the adhesive strip The average width of 2 is between 0.2mm and 5mm. The structure of the dimming window in which the liquid crystal dimming bars are arranged in a grid shape can be realized by the same method as in the first or second embodiment, so the description will not be repeated.

Abstract

The invention discloses a dimming window with liquid crystal dimming strips arrayed in a grid shape. The dimming window is composed of the at least ten liquid crystal dimming strips, bonding glue strips and two transparent substrates. The liquid crystal dimming strips are arrayed to be a grid-shaped pattern or a pattern similar to the grid shape in a parallel, or fan-shaped, or wave-shaped mode. The gap between every two adjacent liquid crystal dimming strips is filled with one bonding glue strip. The liquid crystal dimming strips and the bonding glue strips are clamped between the two transparent substrates. The bonding glue strips are connected with the two transparent substrates in a bonding mode. The dimming window with the liquid crystal dimming strips arrayed in the grid shape can effectively prevent the liquid crystal dimming strips from being torn off by the two transparent substrates, and the strength of the whole dimming window is improved.

Description

technical field [0001] The invention relates to the technical field of light transmittance change under the control of an electric field, in particular to a dimming window in which liquid crystal dimming strips are arranged in a grid shape. Background technique [0002] Ordinary liquid crystal dimming windows are composed of a liquid crystal dimming film sandwiched between two glass plates, and the above three layers are glued together with hot melt adhesive or polymer. The core of the liquid crystal dimming window is the liquid crystal dimming film, which mainly has the following types: [0003] One is based on the principle of polymer dispersed liquid crystal (Polymer Dispersed Liquid Crystal, referred to as PDLC, see US Patent US4671618), the liquid crystal droplets are wrapped in the polymer to form a PDLC structure sandwiched between two plastics whose inner surfaces are coated with a transparent conductive layer Between the films, a liquid crystal dimming film is thus...
