Description
Technical Field
The disclosure belongs to the technical field of electronic equipment, and relates to a polaroid, a display screen device and a mobile terminal.
Background
The polaroid is applied to the field of display screens to provide polarized light for imaging of the display screen. For example, polarizers are provided in display screen devices such as OLEDs or LCDs, which include flexible screens or hard screens having a stable shape.
In the related art, the polarizer is also a very fragile material, and in order to ensure the thin design and structural stability of the polarizer, the thickness dimension and the waterproof requirement are high. As shown in fig. 1, the polarizer includes a pressure-sensitive layer 104, a PVA (polyvinyl alcohol ) layer 101, a protective adhesive layer 103 and a functional layer 102 laminated in this order, wherein the polyvinyl alcohol constituting the PVA layer 101 is easily soluble in water, and the protective adhesive layer 103 has waterproof and adhesive properties. The polarizer is coated with a protective adhesive layer 103 on the upper surface of the PVA layer 101, which prevents moisture from entering along the upper surface of the PVA layer 101. However, when the ambient temperature or humidity changes, moisture may penetrate into the PVA layer 101 through a gap between the lower surface of the PVA layer 101 and the pressure sensitive layer 104, resulting in dissolution of PVA in moisture to fail and decolor.
In addition, the PVA layer 101 is coated with the waterproof and adhesive protective glue layer 103 on both sides thereof, so that the thickness of the polarizer is increased and the rigidity is high. The polaroid is applied to the flexible display screen, and influences the bending effect and the imaging effect of the flexible display screen.

As shown in fig. 2 and 3, the polarizer includes a substrate layer 50, a first protective adhesive layer 30, a polarizing layer 10, a second protective adhesive layer 20, and a functional layer 40 sequentially stacked, wherein the first protective adhesive layer 30 is coated on one side surface of the polarizing layer 10 in a ring shape and is connected with the substrate layer 50 in a gluing manner, the substrate layer 50 in a surrounding area of the first protective adhesive layer 30 is attached to the polarizing layer 10, and the second protective adhesive layer 20 is coated on the other side surface of the polarizing layer 10 and is connected with the functional layer 40 in a gluing manner.
The substrate layer 50, the first protective adhesive layer 30, the polarizing layer 10, the second protective adhesive layer 20 and the functional layer 40 are sequentially laminated to form a polarizer, wherein the substrate layer 50, the first protective adhesive layer 30, the polarizing layer 10, the second protective adhesive layer 20 and the functional layer 40 are all made of light-transmitting materials. Alternatively, the polarizing layer 10 is made of PVA (polyvinyl alcohol ) material. The first protective adhesive layer 30 and the second protective adhesive layer 20 are made of waterproof and light-transmitting adhesive, so that the polarizing layer 10 is attached to the substrate layer 50 and the functional layer 40, and moisture can be prevented from entering the polarizing layer 10. Optionally, the first protective adhesive layer 30 and the second protective adhesive layer 20 are made of the same adhesive, for example, TAC (Tri-cellulose Acetate, cellulose triacetate) material is used for both the first protective adhesive layer 30 and the second protective adhesive layer 20. Optionally, the adhesive used for the first protective adhesive layer 30 and the second protective adhesive layer 20 are different.
In this embodiment, the second protective adhesive layer 20 is coated on one side surface of the polarizing layer 10, so that the functional layer 40 is integrally attached to the polarizing layer 10, and the connection effect is good. The second protective adhesive layer 20 is coated on the surface of the polarizing layer 10, and can improve the flatness and bonding tightness of the functional layer 40. The first protective adhesive layer 30 is in an annular structure, and forms an annular bonding range, and the bonding range of the first protective adhesive layer 30 and the area surrounded by the first protective adhesive layer 30 can prevent water vapor from entering. Therefore, the first protective adhesive layer 30 and the second protective adhesive layer 20 respectively seal two side surfaces of the polarizing layer 10, so that the polarizing layer 10 is sealed by the first protective adhesive layer 30, the substrate layer 50 and the second protective adhesive layer 20, water vapor can be prevented from entering the polarizing layer 10 along two opposite surfaces of the polarizing layer 10, and the waterproof reliability of the polarizing plate is high.
The first protective adhesive layer 30 has an annular structure, and a hollow space is formed around the first protective adhesive layer. The substrate layer 50 is adhesively connected to the first protective adhesive layer 30 and is attached to the polarizing layer 10 along the hollow space, the polarizing layer 10 is directly attached to the substrate layer 50, and the overall thickness of the polarizing plate is small to realize a light and thin design. In addition, the first protective adhesive layer 30 is not coated on the middle area of the polarizing layer 10, so that the overall bending performance of the polarizing plate can be improved, and the bending application effect on the flexible display screen is good. When the polaroid is applied to a display screen device, the polaroid in the area surrounded by the first protective adhesive layer 30 is attached to the surface of the flexible display screen, and the edge part of the polaroid corresponding to the first protective adhesive layer 30 is positioned outside the superposition range of the flexible display screen, so that the design and use of the polaroid can be realized, the waterproof performance can be improved, and the bending performance of the polaroid is good.
As shown in fig. 3 to 5, in an embodiment, the first protective adhesive layer 30 is coated along the surface of the polarizing layer 10, and the coating range extends from the outer circumferential wall of the polarizing layer 10 toward the center direction.
The first protective adhesive layer 30 is annularly coated on the surface of the polarizing layer 10 to form an annular sealing region. In this annular sealing region, moisture is blocked from the outside. In this embodiment, the first protective adhesive layer 30 coats the cementing surface with a preset width from the peripheral wall of the polarizing layer 10 to the central direction of the polarizing layer 10, so that the polarizing layer 10 and the substrate layer 50 are in cementing connection through the first protective adhesive layer 30, and water vapor is prevented from entering the polarizing layer 10 along the gap between the substrate layer 50 and the polarizing layer 10, and the waterproof effect is good. The first protective adhesive layer 30 is disposed at an edge of the polarizer, and optionally, the first protective adhesive layer 30 corresponds to a combination portion of the polarizer and the display screen assembly, and has a small influence on a central polarized light output portion of the polarizer.
As shown in fig. 3 and 4, the coating manner of the first protective adhesive layer 30 on the surface of the polarizing layer 10 may be adjusted according to design requirements, for example, the outer peripheral wall of the first protective adhesive layer 30 extends to the edge of the outer peripheral wall of the polarizing layer 10, and the inner peripheral wall of the first protective adhesive layer 30 is parallel to the outer peripheral wall, so that the coating shape of the first protective adhesive layer 30 changes along with the shape change of the polarizing layer 10. If the polarizing layer 10 is rectangular, the first protective adhesive layer 30 is rectangular ring structure; the polarizing layer 10 has a circular structure, and the first protective adhesive layer 30 has a circular ring structure. As shown in fig. 5, alternatively, the outer peripheral wall of the first protective adhesive layer 30 is flush with the outer peripheral wall edge of the polarizing layer 10, and the shape of the inner peripheral wall of the first protective adhesive layer 30 is set to a fixed shape. For example, the shape of the inner peripheral wall of the first protective adhesive layer 30 is set to a preset shape such as a rectangle, a circle, an ellipse, or the like.
The first protective adhesive layer 30 is coated from the edge of the polarizing layer 10 toward the center direction, and the coating width of the first protective adhesive layer 30 is adjusted accordingly according to the adhesive strength and the waterproof property. Optionally, the first protective glue layer 30 has a different coating width with respect to the edge of the polarizing layer 10. For example, the polarizing layer 10 has a rectangular structure in which the coating width of the first protective adhesive layer 30 in the length direction is larger than the coating width in the width direction. Alternatively, the inner peripheral wall shape of the first protective adhesive layer 30 is elliptical, and the coating width of the first protective adhesive layer 30 in the short axis direction is larger than the coating width in the long axis direction.
In an alternative embodiment, as shown in fig. 3, the coating width of the first protective adhesive layer 30 is the same with respect to the edge of the polarizing layer 10, so that the bonding width of each bonding portion between the first protective adhesive layer 30 and the polarizing layer 10 is the same, and the coating uniformity is good. The coating width is the waterproof area between the first protective adhesive layer 30 and the polarizing layer 10, and the bonding width of each bonding part is the same, so that the waterproof performance of the polarizing layer 10 in each edge direction is consistent, and the waterproof performance is improved. The coating width of the first protective adhesive layer 30 is adjusted to adjust the waterproof area, which is convenient to adjust.
As shown in fig. 2 and 3, in an embodiment, the substrate layer 50 is formed on the polarizing layer 10 and the first protective adhesive layer 30, so that the substrate layer 50 is tightly adhered to the polarizing layer 10. The first protective adhesive layer 30 is coated on the surface of the polarizing layer 10 in an annular manner, wherein the first protective adhesive layer 30 and the polarizing layer 10 positioned in the first protective adhesive layer 30 form an outer surface. The substrate layer 50 is formed on the surface of the polarizing layer 10 and is adhesively connected with the first protective adhesive layer 30, so that the surface of the substrate layer 50 changes along with the height change between the first protective adhesive layer 30 and the polarizing layer 10, and the substrate layer 50 is tightly attached to the first protective layer and the polarizing layer 10. Alternatively, the portion where the substrate layer 50 and the polarizing layer 10 are attached to each other is flexible, so that the substrate layer 50 is molded on the polarizing layer 10.
In an alternative embodiment, the substrate layer 50 includes a first pressure-sensitive adhesive layer 51, a 1/4 lambda slide layer 52 attached to one side surface of the first pressure-sensitive adhesive layer 51, and a second pressure-sensitive adhesive layer 53 attached to the 1/4 lambda slide layer 52, the first pressure-sensitive adhesive layer 51 is adhesively connected to the first protective adhesive layer 30, and the first pressure-sensitive adhesive layer 51 located in the surrounding area of the first protective adhesive layer 30 is attached to the polarizing layer 10.
The first pressure-sensitive adhesive layer 51 and the second pressure-sensitive adhesive layer 53 may be made of PSA (pressure sensitive adhesive, pressure-sensitive adhesive) material, which is a type of adhesive having sensitivity to pressure. The first pressure-sensitive adhesive layer 51 is formed on the surfaces of the first protective adhesive layer 30 and the polarizing layer 10, and can deform along with the deformation of the first protective adhesive layer 30 and the polarizing layer 10 in the height direction, so that the substrate layer 50 is tightly attached to the polarizing layer 10, and the attaching tightness is good. In this embodiment, the first protective adhesive layer 30 is adhesively connected to the surface of the polarizing layer 10, wherein the thickness of the first protective adhesive layer 30 is a micrometer-sized thickness, and the undulation between the polarizing layer 10 and the first protective adhesive layer 30 is small. The first pressure-sensitive adhesive layer 51 is formed on the surfaces of the first protective adhesive layer 30 and the polarizing layer 10, and has good bonding tightness.
The 1/4 lambda slide layer 52 is attached to the first pressure-sensitive adhesive layer 51, and the second pressure-sensitive adhesive layer 53 is attached to the 1/4 lambda slide layer 52, so that the base layer 50 is tightly bonded. Alternatively, the pressure-sensitive adhesive is a high temperature resistant moisture resistant pressure-sensitive adhesive, and an ultraviolet-proof polarizer may be manufactured by adding an ultraviolet-ray blocking component to the first pressure-sensitive adhesive layer 51 and/or the second pressure-sensitive adhesive layer 53. Alternatively, the first pressure-sensitive adhesive layer 51, the second pressure-sensitive adhesive layer 53, the PVA layer, or the TAC layer may be colored, thereby forming a color polarizer.
In an alternative embodiment, the 1/4 lambda slide layer 52 and the second pressure-sensitive adhesive layer 53 are parallel to the first pressure-sensitive adhesive layer 51, so that the thickness of the substrate layer 50 is uniform, and the adhesion effect is good as the first protective adhesive layer 30 and the polarizing layer 10 are fluctuated.
In one embodiment, the functional layer 40 is used to adjust the light propagation parameters of the polarizer, so as to implement different functions of the polarizer. In an alternative embodiment, the functional layer 40 may be provided as one of a surface hardening layer, an anti-glare layer, and a low reflection layer. For example, the functional layer 40 is provided as a surface hardening layer (HC layer); alternatively, the functional layer 40 is an antiglare layer (AG layer) having an antiglare function; alternatively, the functional layer 40 is provided as a low reflection layer (AR layer) having a reflectance that decreases the light irradiated to the polarizer. Of course, the functional layer 40 may be another transparent layer with light propagation parameters for adjusting the polarizer.

For example, the second pressure-sensitive adhesive layer 53 of the base portion is coated with an optical cement 60 such as OCA or OCR. The first protective adhesive layer 30 is formed in a ring shape on the height difference formed by the polarizing layer 10, and then the middle part formed at the base layer 50 is partially recessed to form a step structure, which can be filled with an optical cement 60 such as OCA or OCR, so that the polarizer and the display body 70 are tightly combined, and good bending characteristics and light and thin effects can be maintained.
