Embodiment Construction

[0018] A kind of absorbable reflective sheet of the present invention, such as Figure 1-3 As shown, the reflection sheet 100 is composed of the first PMMA layer 1, the first PMMA foam layer 2, the PC layer 3, the second PMMA foam layer 4 and the second PMMA layer 5 from top to bottom, and the first PMMA Layer 1, the first PMMA foam layer 2, PC layer 3, the second PMMA foam layer 4 and the second PMMA layer 5 are integrally extruded into a sheet structure through an extrusion process, the first PMMA layer 1, the first PMMA foam layer The total thickness of the bubble layer 2, the PC layer 3, the second PMMA foam layer 4 and the second PMMA layer 5 is 0.25mm-0.85mm.

[0019] A kind of absorbable plastic reflection sheet of the present invention, because reflection sheet 100 is made of the first PMMA layer 1, the first PMMA foam layer 2, PC layer 3, the second PMMA foam layer 4 and the second PMMA from top to bottom Composed of layer 5, PMMA has countless tiny bubbles in it aft...

Abstract

The invention discloses a plastic-absorbing reflective sheet, which is composed of a first PMMA layer, a first PMMA foam layer, a PC layer, a second PMMA foam layer and a second PMMA layer from top to bottom, and the above first The PMMA layer, the first PMMA foam layer, the PC layer, the second PMMA foam layer and the second PMMA layer are integrally extruded into a sheet structure. Compared with the prior art, the reflection sheet of the present invention is made of PMMA and PC materials, and co-extrusion process can be adopted during molding. There is no stress problem in the extrusion process, and it can be easily processed into thickness For thicker sheets, the extrusion process is easier to process thicker sheets, and the processing is relatively simple; it is processed into thicker sheets, and at the same time, the reflective sheet formed by PMMA and PC materials is plastic-absorbable. Secondary molding can be carried out, so that the surface of the reflective sheet after extrusion molding can be secondarily molded into various geometric shapes, and the light can be fully reflected and utilized after the geometric shape of the reflective sheet is irradiated by the geometric shape. The use efficiency of light energy is improved, and the reflection effect is better.

Description

technical field [0001] The invention relates to a component of a backlight module, in particular to a reflection sheet of the backlight module. Background technique [0002] The backlight module is one of the key components of the liquid crystal display panel. Since the liquid crystal itself does not emit light, the function of the backlight module is to supply sufficient brightness and uniformly distributed light source so that it can display images normally. Existing backlight modules mainly include: backplane, light guide plate and backlight source, among which the backplane is mostly used as the appearance and protection of components such as backlight source and light guide plate, and generally uses low-cost plastics (such as ABS plastic) This kind of backplane not only cannot achieve the reflection effect on light, but will cause the loss of optical energy. Therefore, the optical loss caused by the backplane must be compensated by the reflector. The existing backlight ...
