Problems solved by technology

[0002] In the prior art, the light guide plate is continuously extruded by a screw extruder. The extruded large plate is cut to form a small plate unit, and then laser processing or hot pressing is performed on the small plate unit. To process various optical cavities, optical bumps or lines, the light guide plate requires multiple processes and various processing equipment, the production efficiency is low, and the production cost is high, so it is necessary to improve

Embodiment

[0029] In an embodiment, a method for producing a light guide plate includes the following steps,

[0030] Pre-reaction, put the liquid MMA monomer into the pre-reaction furnace for heating. The pre-reaction furnace uses a metal tank to hold the MMA monomer and heats it. The temperature is 70-90°C and the time is 0.2-1.5 hours. , the MMA monomer is pre-reacted; in a preferred embodiment, the temperature is 75-85°C; in a preferred embodiment, the time is 0.5-1 hour, the temperature is 80°C, and the time is 0.5 hour;

[0031] filter, filter impurities;

[0032] Pouring, pouring it into a forming mold made of glass material; the forming mold selected in the pouring step includes a glass upper mold and a glass lower mold, and the glass upper mold and glass lower mold are fixed by clamps after being molded, and the glass The lower mold is provided with a casting cavity that matches the shape of the light guide plate, and the bottom surface of the glass upper mold is arranged with ...

Abstract

The invention discloses a production method of a light guiding plate, which comprises the following steps: pre-reacting, filtering, pouring, hot water polymerizing, high temperature polymerizing, cooling, releasing, and film pasting. The light guiding plate is molded in one step, wherein optical recess, optical salient points or lines on the surfaces and the contour shape of the light guiding plate are molded in one step, and the optical recess, the optical salient points or the lines are molded on the surfaces, without the need of cutting, a printing technology or the laser technology. The production method has the advantages that the production process is simple, the production cost is low, and the production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of light guide plates, in particular to a production method of a light guide plate. Background technique [0002] In the prior art, the light guide plate is continuously extruded by a screw extruder, and the extruded large plate is cut to form a small plate unit, and then laser processing or hot pressing is performed on the small plate unit. To process various optical cavities, optical bumps or lines, the light guide plate requires multiple processes and various processing equipment, the production efficiency is low, and the production cost is high, so it is necessary to improve it. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a production method of a light guide plate, which is formed in one step, with simple process, low production cost and high production efficiency. [0004] In order to achieve the above object, the t...
