Embodiment approach

[0017] see figure 2 , which is the first embodiment of the present invention, the light guide plate 10 of the present invention includes a light-transmitting plate 20 and a light-diffusing structure 30 . The light-transmitting plate 20 is made of transparent resin material or glass, and it includes a light incident surface 25, a light exit surface 21 and a bottom surface 23 (such as image 3 shown), wherein the light exiting surface 21 is opposite to the bottom surface 23, and both the light exiting surface 21 and the bottom surface 23 intersect the light incident surface 25.

[0018] Please refer to figure 2 , image 3 with Figure 4 , the light-emitting surface 21 of the light-transmitting plate 20 is provided with a light-diffusing structure 30 . The light diffusing structure 30 includes organic filler spheres 31 and a binder 33 , which can diffuse the light beam emitted from the light emitting surface 21 to improve uniformity. The organic filler spheres 31 are unifo...

Abstract

The invention relates to a light conducting board and process for manufacture, wherein the light conducting board comprises a light-transparent plate and a light diffusion arrangement, the light-transparent plate is made of transparent synthetic resin material or glass, which includes at least incidence plane for receiving light beams, an outgoing plane for letting light beams emit and a bottom plane, the light diffusion arrangement is arranged on the light outgoing plane of the light-transparent plate.

Description

【Technical field】 [0001] The invention relates to a light guide plate and a manufacturing method thereof, in particular to a light guide plate with a diffusion function and a manufacturing method thereof. 【Background technique】 [0002] Since the liquid crystal itself does not have luminous properties, it can only control whether the light passes or not. Therefore, a light source system must be provided for the liquid crystal display panel, such as a backlight system. Its function is to provide a surface light source with sufficient brightness and uniform distribution for the liquid crystal display panel. [0003] The existing backlight system is composed of a light source, a reflector, a light guide plate, a diffuser plate and a prism plate, among which the light guide plate is the key component of the backlight system, and its function is to guide the light emitted by the point light source or the line light source to be scattered and totally reflected by the light guide pl...
