Abstract

The present invention discloses a thermoforming method applicable for manufacturing a plate assembly having a first plate and a second plate. The thermoforming method comprises the steps of disposing the second plate on a lamination surface of the first plate; putting the first plate and the second plate into a first mold and a second mold respectively; heating and pressing the first mold and the second mold to deform any one of the lamination surfaces of the first plate and the second plate in order to laminate the first plate and the second plate; and opening the first mold and the second mold to remove the plate assembly. The first plate can be a light guide plate, and the second plate can be a reflector.

Description

technical field

[0001] The present invention relates to a thermocompression forming method and its plate component, in particular to a thermocompression forming method for improving the manufacturing process of a light guide plate laminating a reflection sheet and reducing the process and its plate component. Background technique

[0002] In general, backlight modules such as figure 1 As shown, it is mainly composed of a tube light source 90 (Light Source), a reflector 91 (Reflector), a light guide plate 92 (Light Guide Plate), a diffusion sheet 93 (Diffusion Sheet) and a prism sheet 94 (Prism Sheet). Such as figure 2 As shown, the basic working principle of the backlight module is as follows:

[0003] S1: Convert the lamp light source into a surface light source through the light guide plate.

[0004] S2: Use the reflection sheet at the bottom of the light guide plate to reflect the light emitted from the light guide plate back to the inside of the light guide plate. ...

[0052] According to the first embodiment, the present invention further proposes a second embodiment for further illustration.

[0053] see Figure 5 , which is a schematic diagram of the second embodiment of the thermoforming method of the present invention. As shown in the figure, the thermocompression forming method of the present invention is suitable for manufacturing plate components. The plate components include a first plate 21 and a second plate 22. In this embodiment, the first plate 21 is preferably a light guide plate, which can The light guide plate is made of thermoplastic material, and the second plate 22 is preferably a reflective sheet, which can be made of thermoplastic material. The material for making the first sheet 21 can be polymethylmethacrylate (Polymethylmethacrylate, PMMA), cycloolefin polymer (Cycio Olefins Polymer, COP) or polycarbonate (Polycarbonate, PC) and other materials, all of which can be used to make the conductor Light board; the second...
