Embodiment Construction

[0019] see figure 2 , is a flow chart of the manufacturing method of the light guide plate mold core of the present invention, which includes the following steps:

[0020] Step 1, providing a substrate, wherein the substrate material is generally silicon or metal material.

[0021] Step 2, designing the mold core pattern, which can be designed in various patterns or shapes, such as rectangular dot matrix, circular dot matrix and so on. Complete the signal processing of the mold core pattern in the computer, and use the pattern signal to control the processing by the computer.

[0022] Step 3, according to the designed mold core pattern, the probe is used to scan the surface of the substrate to form a desired pattern on the surface of the substrate.

[0023] The precision of the light guide plate mold core manufactured by the above method can be less than 100 nanometers, which is much higher than that of the mold core manufactured by the ordinary method.

Abstract

The making process of mold kernel for light guiding board includes the following steps: providing one base board; completing mold kernel pattern design in computer and computer controlled mold kernel machining; and forming required pattern on the base board via scanning probe lighography, so as to form high precision mold kernel for light guiding board.

Description

【Technical field】 [0001] The invention relates to a method for manufacturing a mold core of a light guide plate, in particular to a method for manufacturing a mold core of a light guide plate with a high-precision pattern. 【Background technique】 [0002] In recent years, with the increase in color and size of liquid crystal display devices, its application fields have become more and more extensive, such as notebook computers, various desktop computers, and LCD TVs. However, since the liquid crystal display device is a passive component and cannot emit light by itself, a light source system, such as a backlight module, needs to be used as the light source of the liquid crystal display device. Among them, the light guide plate is an important component in the backlight module, used to guide the transmission direction of the light beam emitted from the light source, and convert the line light source or point light source into a surface light source. [0003] In order to impro...
