Problems solved by technology

[0004] 1. When producing backlight with white reflective film, if there are small particles of foreign matter between the white reflective film and the light guide plate, or between the white reflective film and the plastic iron, the white reflective film will be squeezed Compression deformation, forming optical refraction, after the backlight product is lit, it will form white or black spots

Embodiment Construction

[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "another end" The orientation or positional relationship indicated by etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, use a specific Azimuth configuration and operation, therefore, should not be construed as limiting the invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and should not be understood ...

Abstract

The invention discloses a novel composite white reflective film which comprises a white reflective film. An adhesive layer is arranged on the outer surface of the upper end of the white reflective film. A transparent film is arranged on the outer surface of the upper end of the adhesive layer. The outer surface of the upper end of the white reflective film is fixedly connected with the outer surface of the lower end of the adhesive layer. The outer surface of the upper end of the adhesive layer is fixedly connected with the outer surface of the lower end of the transparent film. The thickness of the white reflective film is 55 microns, and the thickness of the transparent film is 25 microns. According to the novel composite white reflective film, generation of white points and black points can be reduced, the situation that white balls are formed after an LCM is lightened due to extrusion deformation of the white reflective film can be prevented, foreign matter defects in the production process of backlight source products are avoided, the two needed main materials and processes can be independently completed by domestic manufacturers, the industrial cost can be reduced, the domestic selling price of a silver-plated specular reflective film can be further reduced, and a better use prospect is brought.

Description

technical field [0001] The invention relates to the field of backlight source products, in particular to a novel composite white reflective film. Background technique [0002] White reflective film is available for all sizes of backlight modules. The backlight is a light source located behind the liquid crystal display, and its luminous effect will directly affect the visual effect of the liquid crystal display module. [0003] The existing white reflective film has the following two disadvantages when used: [0004] 1. When producing backlight with white reflective film, if there are small particles of foreign matter between the white reflective film and the light guide plate, or between the white reflective film and the plastic iron, the white reflective film will be squeezed Compression deformation, forming optical refraction, after the backlight product is lit, it will form white or black spots. [0005] For backlight products using white reflective film, during the a...
