Manufacturing method of light guide plate and manufacturing method of display device

Abstract

The embodiment of the present invention discloses a method for manufacturing a light guide plate, including: providing a polymer material; providing a foaming agent; and mixing the polymer material and the foaming agent in a preset manner and injecting them into a molding mold to A light guide plate containing air bubbles generated by the blowing agent was produced. The embodiment of the invention also discloses a manufacturing method of the display device. The embodiment of the present invention can reduce the weight of the light guide plate without reducing the thickness of the light guide plate by forming air bubbles in the light guide plate; in addition, the air bubbles in the light guide plate can destroy the total reflection of light in the light guide plate, resulting in fogging The light-emitting effect enables more light to be emitted from the light-emitting surface of the light guide plate, and finally achieves the technical effects of reducing the weight of the light guide plate and improving display uniformity while ensuring the thickness of the light guide plate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a light guide plate and a method for manufacturing a display device. Background technique [0002] At present, in the field of display technology, a surface light source is often formed by combining a light guide plate with a side-type light source. The light emitted by the side-type light source enters the light guide plate from the incident surface on one side of the light guide plate, and then passes through the light guide point After being emitted and diffused, it emits from the light-emitting surface of the light guide plate to provide the light required for the display panel to work. [0003] However, in order to make full use of the light source emitted by the LED, it is necessary to make most of the light into the light guide plate. The above problems are often solved by making the light guide plate made of a certain thickness, although the li...

Problems solved by technology

[0003] However, in order to make full use of the light source emitted by the LED, it is necessary to make most of the light into the light guide plate. The above problems are often solved by making the light guide plate made of a certain thickness, although the light guide plate made by this method can increase the light intensity. The incident rate, but it will also lead to an increase in the thickness of the display device with the light guide plate, which does not conform to the current development trend of light weight display devices, and the uniformity of the emitted light is not good
