Embodiment Construction

[0018] see figure 2 , is a schematic perspective view of the first embodiment of the light guide plate of the present invention. The light guide plate 20 includes a substrate 21 and a plurality of transparent particles 22 . The substrate 21 is a rectangular transparent substrate. The substrate 21 includes a surface 24 having a groove array 25 , and the groove array 25 is a V-shaped groove array. The size of the plurality of transparent particles 22 is 10 -9 rice. The plurality of transparent particles 22 are evenly adhered to the groove wall of each groove of the groove array 25 through an adhesive layer 23 . The adhesive layer 23 is a transparent adhesive layer.

[0019] The V-shaped groove array shape of the groove array 25 can control the outgoing angle of the light and converge the outgoing light at a certain angle, which can make full use of the outgoing light and improve the light utilization rate. The groove array 25 controls the outgoing angle of the light and ma...

Abstract

The invention provides a light conducting plate for liquid crystal display device, which comprises a substrate and a plurality of transparent particles, wherein the substrate includes a surface having trench arrays, the transparent particles are adhered onto the surface through a glue layer. The light conducting board has high utilization rate of light, and can effectively control the angle of departure for the light rays. The invention also provides the method of making the light conducting board.

Description

【Technical field】 [0001] The invention relates to a light guide plate used in a liquid crystal display device and a manufacturing method thereof. 【Background technique】 [0002] In recent years, with the colorization and enlargement of liquid crystal displays, their application fields are more extensive, such as mobile phones, notebook computers, and various desktop computers. Since the liquid crystal display is a passive component and cannot emit light by itself, a light source system needs to be used as the light source of the liquid crystal display. Such as the backlight module, in which the light guide plate is an important component in the backlight module, which is 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 to emit. [0003] At present, the manufacturing methods of the light guide plate can be divided into etching method (Etching), laser p...
