Abstract
The invention provides mouth-shaped glue. The Mouth-shaped glue comprises base material, a reflective layer used for reflection on the surface of one side of the base material, a heat conductive layer used for heat conduction and light shading on the other surface of the base material, a first glue layer covering the surface of the reflective layer used for adhesion, a thin film layer covering the heat conduction layer used for protection and a second glue layer covering the surface of the thin film layer used for adhesion. The invention further provides a backlight assembly comprising a middle frame and an upper prism piece of the middle frame. The mouth-shaped glue comprises a mouth-shaped glue body. The reflective layer is opposite to the upper prism piece and adhered to the upper prism piece through a first glue layer. Compared with the prior art, the mouth-shaped glue has the following beneficial effects: one side of the base material is provided with the heat conductive layer used for light shading and heat conduction so that heat of the backlight assembly and a liquid crystal panel can be conducted; heat dissipation effect is improved; the surface on the other side of the base material is provided with the light reflective layer so that light emitting the mouth-shaped glue is reflected; light loss is reduced; and brightness of the backlight assembly is improved.
Description
technical field [0001] The invention relates to a liquid crystal display panel technology, in particular to a word-of-mouth glue and a backlight assembly. Background technique [0002] Electronic information machine products have always been favored by people, but electronic products will heat up after a period of continuous use, which affects their normal use, especially mobile phones. In view of this situation, the relevant personnel focused on the heat dissipation performance of the whole machine. The liquid crystal display device (LCD) is a key component of electronic information machine products, and the backlight assembly is an important part of the liquid crystal display device, which provides a light source for the liquid crystal display device, and the word glue is an important part of the backlight assembly. Shading, connecting open-cell (liquid crystal panel) and backlight components, but the base material of the word-of-mouth adhesive is black PET (polyethylene ...
