Description
Technical Field
The invention relates to a polaroid, a display panel and a display comprising the polaroid.
Background
As the thickness of the display panel is reduced with the thinning of the display, the thickness of the liquid crystal panel has been increased from 0.5mm, which has been the mainstream in the past, to 0.2 mm. The display panel is used in combination with a polarizer, which is an optical element with a multilayer structure, and is often applied to a display, and is attached to the display panel to play a role in polarizing light. Referring to fig. 1, a polarizer 1 includes a polarizing film 10 having a polarizing function at the center, triacetyl cellulose (TAC) films 11 for protecting both sides of the polarizing film 10, a protective film 12 disposed on one side of the TAC film 11, an adhesive layer 13 disposed on the other side of the TAC film 11, and a release film 14 coated on the adhesive layer 13. The polarizing film is generally made of polyvinyl alcohol (PVA) stretched in a certain direction and dyed with a dichroic dye, and the stretched PVA film shrinks in the stretching direction when temperature or humidity changes. After a polarizer is attached to a thin display panel, the display panel is easily warped due to the shrinkage stress of the polarizing film, and the yield and the display performance of the display are reduced. Among them, when the display panel is warped in a direction toward the display surface (i.e., the surface viewed by the user) to be a regular U shape, it is called "regular warping"; when the display panel is warped in a direction away from the display surface and is in an inverted U shape, the display panel is called "negative warped".

In order to achieve the above object, the present invention provides a polarizer, including a body having a polarization function and an adhesive layer formed on a surface of the body, where the adhesive layer includes a plurality of adhesive regions, the plurality of adhesive regions are arranged in parallel along any dimension direction of the surface of the body, and viscosities of the plurality of adhesive regions are sequentially increased or decreased from a periphery of the adhesive layer to a center of the adhesive layer; or the thicknesses of the viscose glue areas are sequentially increased or decreased from the periphery of the viscose glue layer to the central part of the viscose glue layer; or the viscosities of the plurality of viscose areas are monotonically and sequentially increased or decreased from the periphery of the viscose layer to the central part of the viscose layer, and the viscose thicknesses of the plurality of viscose areas are correspondingly monotonically and sequentially decreased or sequentially increased from the periphery of the viscose layer to the central part of the viscose layer.
Furthermore, the invention also provides a display panel and a display using the polaroid.
The polaroid is coated with the glue materials with different viscosities and/or different thicknesses in different surface areas, and when the polaroid is attached to the display panel, the acting forces of the different surface areas on the display panel are different, so that the shrinkage stress borne by the display panel can be balanced, the problem of warping deformation of the display panel is solved, and the display quality is improved.

Description of the main elements
The following detailed description will further illustrate the invention in conjunction with the above-described figures.
Detailed Description
The inventor of the present invention has found that when a polarizer is attached to a thinned display panel (with a thickness of less than 0.5mm), the display panel may be warped. For example, when a polarizer is attached to a display panel having a thickness of 0.4mm, warpage is observed in the peripheral region of the display panel, especially in the four corners, with different degrees of curvature ranging from-1 mm to 0.4mm compared to the horizontal plane. Further research shows that the problem is mainly caused by the fact that the thickness of the display panel thinned at the present stage is reduced to be less than 0.5mm and is reduced to 0.2mm, panel glass of the display panel is easy to bend and deform due to external force, and when the polarizer is attached, the whole display panel is easy to be subjected to shrinkage stress of the polarizer, and is warped, positively warped or negatively warped. Since the warping direction of the display panel caused by the shrinkage stress of the polarizing film should be the same for the display panel and the polarizing film of the same material, the warping direction of the display panel can be predicted before the polarizer is attached. The present invention has been made in view of solving the warping problem.
The polaroid comprises a body with a polarization function and an adhesive layer formed on the surface of the body, wherein the adhesive layer comprises a plurality of adhesive areas which are arranged in parallel along any dimension direction of the surface of the body, and the viscosities of the plurality of adhesive areas are sequentially increased or decreased from the periphery of the adhesive layer to the central part of the adhesive layer; or the thicknesses of the viscose glue areas are sequentially increased or decreased from the periphery of the viscose glue layer to the central part of the viscose glue layer; or the viscosities of the plurality of viscose areas are monotonically and sequentially increased or decreased from the periphery of the viscose layer to the central part of the viscose layer, and the viscose thicknesses of the plurality of viscose areas are correspondingly monotonically and sequentially decreased or sequentially increased from the periphery of the viscose layer to the central part of the viscose layer. The polarizer may be rectangular or may be any shape other than rectangular.
