Problems solved by technology

[0004] However, the above-mentioned backlight module requires the combination of multiple optical films to achieve the ideal backlight effect. The combination of multiple optical films will not only increase the number of optical components and increase the manufacturing cost, but also increase the process required for assembly. with time

Embodiment Construction

[0042] see figure 2 3 , which is an embodiment of the display device and the composite optical film of the present invention, discloses a backlight module 90 and the composite optical film 10 applied to the backlight module 90 . The backlight module 90 includes a backlight 91 , a light guide plate 92 , a reflection sheet 93 , and a composite optical film 10 . The backlight module 90 is used to provide backlight to a display panel 94 , wherein the composite optical film 10 is used to achieve the effects of diffusion and light collection, so as to enhance the front intensity of the backlight. The composite optical film 10 includes a flexible substrate 11 , a plurality of protruding light-collecting prisms 12 and a plurality of transparent micelles 13 .

[0043] The flexible substrate 11 is made of light-transmitting materials, such as polystyrene (PS), polyvinyl chloride (PVC) or polymethyl methacrylate (PMMA), for allowing light to pass through and can be bent , deformation....

Abstract

The invention relates to a composite optical film and a manufacturing method thereof; the composite optical film comprises a flexible substrate, a plurality of convex light-collecting prism and a plurality of transparent micelles; the light-collecting prisms are arranged on the flexible substrate and used for collecting light; the transparent micelles are respectively arranged between corresponding light-collecting prisms; furthermore, a clearance area exists between all transparent micelles and the light-collecting prisms; the transparent micelles are used for light diffusion and protection of light-collecting prisms; the transparent micelles are used for light diffusion and protection of light-collecting prisms; the composite optical film uses single film to replace the combination of a plurality of optical films, simplifies the structure of the backlight module and reduces the manufacturing cost of the backlight module.

Description

technical field [0001] The invention relates to an optical film applied to a backlight module, in particular to a composite optical film and a manufacturing method thereof. Background technique [0002] Liquid crystal displays must rely on light to penetrate the liquid crystal layer, so that the human eye can observe the effects of changes in the composition of the liquid crystal layer. In addition to the traditional small monochrome liquid crystal display module which uses external light reflection, the existing liquid crystal displays all use a backlight module to project light from the back side of the liquid crystal layer. The light provided by the backlight module must evenly penetrate the liquid crystal layer, and the light projected to the liquid crystal layer must have uniform luminance. [0003] refer to figure 1 , which is a schematic cross-sectional view of a display device in the prior art. The display device in the prior art mainly includes components such as...
