Embodiment Construction

[0028] The light guide plate provided by the present invention and its preparation method are described below in conjunction with the accompanying drawings:

[0029] Such as Figure 11 As shown, the preparation method of the light guide plate provided by the present invention comprises the following steps:

[0030] Step 10, provide an embossing machine with a plurality of indenters of different shapes; the indenters are generally made of diamond and other hard and wear-resistant materials through fine processing, and have a long service life.

[0031] The indenter has such figure 1 , image 3 , Figure 4 , Figure 5 The different pyramid or conical shapes shown may also have other shapes such as spherical or prismatic, which can be freely designed according to optical design requirements, and are not limited to cone, spherical or cylindrical. The conical indenter can imprint a groove with a V-shaped axial section, the cylindrical indenter can imprint a groove with a U-sh...

Abstract

The present invention relates to a kind of light conducting board and its production process. The light conducting board includes one light incoming plane, one light outgoing plane, and one reflecting plane opposite to the outgoing plane. Of these three planes, at least one has notches with arced axial cross section and notches with angular axial cross section, and these two kinds of notches are arranged regularly in preset optical pattern. The notches with arced axial cross section can regulate light beam area homogeneity, and the notches with angular axial cross section can regulate the direction of the light beam for the light beams to outgo from the light conducting board in certain angular distribution and thus increased light intensity. Therefore, the light conducting board has homogeneous and bright outgoing light, and is suitable for use in back light module for non-selfluminescent plane display. The present invention also provides the making process of the light conducting board.

Description

【Technical field】 [0001] The invention relates to a light guide plate and a preparation method thereof, in particular to a light guide plate used for a backlight module of a non-self-illuminating flat panel display and a preparation method thereof. 【Background technique】 [0002] The light source of the non-self-illuminating flat-panel display (such as liquid crystal display) comes from the flat light source module, the transmissive liquid crystal display uses the backlight module, and the reflective display uses the front light module. The backlight module is a module structure that converts linear light sources (such as cold cathode tubes) or point light sources (such as light-emitting diodes) into planar light sources with high brightness and surface uniformity. [0003] Such as Figure 12 and Figure 13 As shown, it is the structure of a traditional backlight module: the cold cathode tube 1 is placed on the end surface of the light guide plate 2, the reflective surface ...
