Description

Technical Field

[0001] This utility model relates to the field of brightness enhancement film technology, and in particular to a gray-white reflective polarizing brightness enhancement film. Background Technology

[0002] Existing reflective polarizing brightening films include reflective polarizing brightening films, which are structures consisting of 500-1000 layers of two polymers with different refractive indices stacked alternately, each layer being about 50nm thick. The manufacturing process is extremely difficult, and a certain percentage of finished products have deviations in refractive index and thickness control, resulting in a reddish tint under reflected light. However, reflective polarizing brightening films used in LCDs are required to have a grayish-white background. If the background of the reflective polarizing brightening film is reddish, it will affect the color reproduction of the LCD.

[0003] In existing technologies, the reddish background color of reflective polarizing brightening films affects the color reproduction of LCDs, a problem that needs to be addressed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a gray-white reflective polarizing brightening film that addresses the above-mentioned technical deficiencies. This film solves the problem in the prior art where the reddish background color of the reflective polarizing brightening film affects the color reproduction of the liquid crystal display.

[0005] The technical solution adopted by this utility model is: to provide a gray-white reflective polarizing brightening film, comprising a release film, a diffusion adhesive, a reflective polarizing brightening film, and a protective film arranged sequentially; and further comprising: A complementary color adhesive layer is disposed between the reflective polarizing brightening film and the protective film. The complementary color adhesive layer is a color-matching layer that is complementary to the base color of the reflective polarizing brightening film and is used to set the base color to grayish-white. The complementary color adhesive layer is cyan. A base film is disposed between the complementary color adhesive layer and the protective film.

[0006] To further optimize this technical solution, the base film is a PET base film.

[0007] To further optimize this technical solution, the thickness of the complementary color adhesive layer is 10um-20um.

[0008] The beneficial effects of this utility model are as follows: 1. Add a complementary color layer to the reddish reflective polarizing brightener. By adjusting the cyan and red tones, the base color is adjusted to grayish-white to meet the color reproduction requirements of the LCD monitor. Attached Figure Description

[0010] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0011] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0012] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0013] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0014] like Figure 1-2 As shown, a gray-white reflective polarizing brightening film includes a release film 1, a diffusion adhesive 2, a reflective polarizing brightening film 3, and a protective film 6 arranged sequentially; it also includes: a complementary color adhesive layer 4 disposed between the reflective polarizing brightening film 3 and the protective film 6, the complementary color adhesive layer 4 being a color-matching layer complementary to the base color of the reflective polarizing brightening film 3, used to color the base color as gray-white, the complementary color adhesive layer 4 being cyan; and a base film disposed between the complementary color adhesive layer 4 and the protective film 6.

[0015] The base film is a PET base film 5.

[0016] In the illustration, the reflective polarizing brightening film 3 is composed of alternating layers of polymers, and its interior is displayed as multiple lines, not grayscale.

[0017] In use, existing reflective polarizing brightening films include a release film 1, a diffusion adhesive 2, a reflective polarizing brightening film 3, and a protective film 6 stacked sequentially. The structure of the reflective polarizing brightening film 3 gives the background color a reddish tint. A color-tone layer is added between the reflective polarizing brightening film 3 and the protective film 6 to make the background color grayish-white. The color-tone layer includes a complementary color adhesive layer 4 and a base film. The complementary color adhesive layer 4 is cyan and is located at the lower end of the reflective polarizing brightening film 3. The base film is located at the lower end of the complementary color adhesive layer 4 and above the protective film 6. The base film is a PET base film 5.

[0018] Based on the principle that white light is produced by adding equal amounts of two complementary optical colors, a reddish reflective polarizing brightener ( Figure 1 Add a complementary cyan layer 4 ( Figure 2 ), can be used to produce gray-white reflective polarizing brightening films ( Figure 2 ).

[0019] Furthermore, the thickness of the complementary color adhesive layer 4 is 10um-20um.

[0020] In use, cyan nano-pigment is added to the complementary color adhesive layer 4. With a constant thickness, the greater the weight proportion of cyan nano-pigment added, the deeper the cyan. Color matching is also related to the thickness of the complementary color adhesive layer 4; with the same proportion of cyan nano-pigment, a thicker layer results in a deeper cyan. The proportion of cyan nano-pigment added can be 0.05%-0.15%, and the thickness of the complementary color adhesive layer 4 is 10-20 μm.

[0021] It is understood that this utility model has been described through some embodiments, and those skilled in the art will know that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
