Problems solved by technology

[0002] The current manufacturing method of light guide plate is to make silk screen light guide dots on acrylic board, PC board or other transparent boards, laser dots, injection molding or directly heat pressing or drawing lines on acrylic boards. Bare boards have more or less disadvantages such as high investment in equipment, need for skilled workers, and high cost.

Embodiment Construction

[0015] combine figure 1 , figure 2 , a method for manufacturing a light guide plate of the present invention is mainly used in the manufacture of a light guide plate for a backlight module or a flat light source, comprising the following steps:

[0016] Step 1: Prepare the light reflective material 1, the light reflective material 1 has a certain viscosity, and the light reflective material 1 can be prepared with high reflectivity materials such as silicon oxide, magnesium oxide, and titanium oxide;

[0017] Step 2: Print or coat the prepared light reflective material 1 on the reflective film or reflective paper 2 according to a certain shape and distribution method to make a uniform light reflective film;

[0018] Step 3: Dry the homogeneous reflective film, and then attach the release film (not shown in the release film diagram);

[0019] Step 4: Cut the dried homogeneous reflective film according to the size of the acrylic plate or other light-transmitting plate 2;

Abstract

The invention discloses a manufacturing method of an LGP. The method comprises manufacturing processes as follows: a light reflective material is prepared, a reflective film or a piece of reflective paper is printed or coated with the light reflective material, a release film is laminated, cutting and lamination are performed according to a light-transmitting plate, and the like. According to the manufacturing method, a uniform light reflective film can be pre-coiled and manufactured, and the uniform light reflective film is cut according to the size of an Acrylic plate or other light-transmitting plates and laminated to the Acrylic plate, so that a factory for manufacturing the LGP doesn't need large equipment (only needs a cold lamination machine or a laminating machine), no professional skilled worker is required during lamination, and the product cost is reduced.

Description

technical field [0001] The invention relates to a manufacturing method of a light guide plate. Background technique [0002] The current manufacturing method of light guide plate is to make silk screen light guide dots on acrylic board, PC board or other transparent boards, laser dots, injection molding or directly heat pressing or drawing lines on acrylic boards. Bare boards have more or less disadvantages such as high investment in equipment, need for skilled workers, and high cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a simple manufacturing method of the light guide plate and reduce the manufacturing cost of the light guide plate. [0004] In order to solve the above technical problems, the technical solution of the present invention is: a method for manufacturing a light guide plate, which is mainly used for making a light guide plate of a backlight module or a flat light source, comprising the fo...
