Description
Technical Field
The invention relates to the technical field of display systems, in particular to a dimming component, a manufacturing method of the dimming component, dimming glass, a display device and a vehicle.
Background
Dimming refers to the phenomenon of transparency or opacity when the dimming material is switched on or off by using the transmission and scattering phenomena of the dimming material. Dimming components (e.g., PLDC, polymer dispersed liquid crystal) are widely used in large area projection screens, architectural and automotive doors and windows, glass curtain walls, interior partitions of rooms, and the like.
Taking the PLDC as an example, when the PLDC is placed in laminated glass to prepare the light control glass, since the PLDC needs to be bonded with the glass through an adhesive layer, but an inner liquid crystal high polymer in a light control functional layer of the PDLC is easy to react with a plasticizer in the adhesive layer, the PLDC can be caused to fail, and further the light control glass can be caused to fail.
The edge sealing process can prevent the plasticizer in the adhesive layer from entering the light control functional layer of the PLDC to react with the liquid crystal high polymer, but the existing edge sealing process generally adopts a half-cutting process to cut steps, then uses gluing equipment to glue in the area, and then carries out curing, so that the following problems exist:
1. gluing the half-cut steps, wherein due to the action of gravity, gluing is inevitably uneven, the whole edge sealing area is thin at the top and thick at the bottom, so that the upper part is relatively weak, and the risk of edge sealing defects is caused; 2. the adhesive surface of the adhesive only has a single side surface and a bottom surface, the adhesive area is small, the adhesion is not firm, and the edge sealing adhesive is easy to debond.
Disclosure of Invention
Based on the light adjusting component, the invention provides a light adjusting component, a manufacturing method of the light adjusting component, light adjusting glass, a display device and a vehicle. The dimming assembly is edge-sealed by the bonding block and the decorative layer, so that when dimming glass is prepared subsequently, a plasticizer in the laminated adhesive layer can be prevented from reacting with a functional substance in the dimming assembly, and the dimming assembly is prevented from losing efficacy. And simultaneously, the problems of uneven gluing and easy debonding of edge sealing glue are solved.
The technical scheme provided by the invention comprises the following steps:
a dimming assembly comprises a first transparent substrate, a first transparent conductive layer, a light control functional layer, a second transparent conductive layer, a second transparent substrate, a bonding block and a decorative layer;
the first transparent substrate, the first transparent conducting layer, the light control function layer, the second transparent conducting layer and the second transparent substrate are sequentially stacked, and the light adjusting assembly is provided with a bonding hole which penetrates through the second transparent substrate, the second transparent conducting layer and the light control function layer from the surface of the second transparent substrate to the first transparent conducting layer;
the bonding block comprises a filling part and an extending part which is integrally formed with the filling part, the filling part is filled in the bonding hole and is bonded with the hole wall of the bonding hole, and the extending part is positioned on the second transparent substrate;
the decorative layer is arranged on one side of the extension portion, which is far away from the second transparent substrate.
In one embodiment, the aperture of the adhesion hole in the light control functional layer section is greater than or equal to the aperture thereof in the second transparent substrate section, and/or the aperture of the adhesion hole in the light control functional layer section is greater than or equal to the aperture thereof in the second transparent conductive layer section.
In one embodiment, the boundary of the orthographic projection of the adhesion hole on the first transparent substrate from the side wall of the optically controlling functional layer section does not exceed the boundary of the orthographic projection of the extension part on the first transparent substrate.
In one embodiment, the decorative layer completely covers or partially covers the outer extension.
In one embodiment, the decorative layer has a predetermined shape, and the decorative layer defines at least a boundary of the dimmable area.
The invention also provides a preparation method of the dimming component, which comprises the following steps:
sequentially laminating a first transparent substrate, a first transparent conductive layer, a light control functional layer, a second transparent conductive layer and a second transparent substrate;
removing material from the surface of the second transparent substrate downwards to form an adhesion hole penetrating through the second transparent substrate, the second transparent conductive layer and the light control functional layer to the first transparent conductive layer;
filling a bonding material into the bonding hole, and enabling the bonding material to overflow the bonding hole;
and placing a decorative material on the bonding material, pressing and curing, wherein the bonding material forms a bonding block with a filling part and an extending part, and the decorative material forms a decorative layer.
In one embodiment, the forming of the adhesion hole further comprises:
and injecting a solvent into the hole to dissolve a part of the light control function layer, so that the aperture of the adhesion hole in the light control function layer section is larger than or equal to that in the second transparent substrate section, and/or so that the aperture of the adhesion hole in the light control function layer section is larger than or equal to that in the second transparent conducting layer section.

In one embodiment, the glass substrate and the dimming component are bonded through an adhesive layer.
A display device includes a fixing structure and the light control glass mounted on the fixing structure.

Compared with the traditional scheme, the invention has the following beneficial effects:
the light control functional layer of the light adjusting component is subjected to edge sealing by the bonding block and the decorative layer. When the dimming glass is prepared subsequently, the plasticizer in the laminated adhesive layer can be prevented from reacting with the functional substance of the light control functional layer to cause the failure of the dimming assembly. The bonding blocks can be uniformly distributed in the edge sealing area, the bonding area of the bonding blocks is large, the bonding strength is high, the bonding blocks are not easy to fall off, and the edge sealing defect is reduced. Moreover, the decorative layer is arranged, so that the decorative effect is very strong, the color and the type of the decorative layer are selectable, and the decorative layer is more attractive; and when the dimming glass is prepared subsequently, the decorative layer is laminated inside the glass substrate, so that the decorative layer is isolated from directly contacting the outside, and the problem of corrosion, aging and color change of the decorative layer can be avoided. After the dimming assembly is prepared into the dimming glass through laminating adhesive, the edge of a dimming area of the dimming glass cannot become transparent after thermal aging for 2000 hours at 90 ℃.

Taking the PLDC as an example, when the PLDC is placed in laminated glass to prepare the light control glass, since the PLDC needs to be bonded with the glass through an adhesive layer, the inner liquid crystal high polymer in the light control functional layer of the PDLC is easy to react with the plasticizer in the adhesive layer, which may cause the failure of the PLDC, and further cause the failure of the light control glass. The graph of the comparison between the failed dimming glass and the good dimming glass is shown in fig. 1, the failed dimming glass is arranged on the left side, and the edge of the dimming glass is transparent.
The edge sealing process can prevent a plasticizer in the adhesive layer from entering the light control functional layer of the PLDC to react with a liquid crystal high polymer, but the existing edge sealing process generally adopts a half-cutting process to cut out steps, then adhesive is applied to the area by using adhesive applying equipment and then cured, as shown in figure 2, 10 is a first transparent substrate, 11 is a first transparent conductive layer, 12 is the light control functional layer, 13 is a second transparent conductive layer, 14 is a second transparent substrate, and 15 is edge sealing adhesive, so that the problems of uneven adhesive application and easy debonding of the edge sealing adhesive are solved.

The first transparent substrate 21, the first transparent conductive layer 22, the light control function layer 23, the second transparent conductive layer 24, and the second transparent substrate 25 are sequentially stacked.
Alternatively, the first and second transparent substrates 21 and 25 include, but are not limited to, PET (polyethylene terephthalate) substrates.
In this embodiment, the dimming component is a PLDC, and the light control functional layer contains a liquid crystal polymer.
In this embodiment, the light control module is provided with a bonding hole penetrating from the surface of the second transparent substrate 25 to the first transparent conductive layer 22 through the second transparent substrate 25, the second transparent conductive layer 24 and the light control function layer 23.
