Embodiment Construction
[0029] Please refer to FIG. 1 , which is a schematic structural diagram of a light guide plate with multi-directional structure according to the first embodiment of the present invention. The light guide plate 100 of this embodiment can be applied to a backlight module (not shown). The light guide plate 100 may include a main body 120 , a plurality of first microstructures 140 and a plurality of second microstructures 160 . Through the first microstructure 140 and the second microstructure 160 disposed on the main body 120 , it is possible to simultaneously change and adjust the exit angle and optical trend of the light emitted from the light guide plate 100 .
[0030] In the light guide plate 100, the main body 120 can be a light-transmitting plate or other equivalent light-transmitting components. The main body 120 mainly includes a light incident surface 122 , a light output surface 124 and a reflective surface 126 . The reflective surface 126 and the light emitting surfa...

The invention provides a light guide plate with a multi-direction structure. The light guide plate comprises a body, a plurality of first microstructures and a plurality of second microstructures. The body comprises an incident face, an emergent face or a reflecting face. The reflecting face is opposite to the emergent face. The incident face is connected with the emergent face and the light reflecting face. The first microstructures are arranged on the emergent face or the light reflecting face and a first microstructure system is arranged along the first extension direction. The second microstructures are arranged on the emergent face or the light reflecting face and a second microstructure system is arranged along the second extension direction. The second microstructures and the first microstructures are on the same plane and are intersected with each other. Each of the second microstructures is in a single strip type and width of each of the second microstructures is reduced gradually from one end close to the incident face to the other end far away from the incident face.
Description
technical field [0001] The present invention relates to a light guide plate, and in particular to a light guide plate with multi-directional structure. Background technique [0002] The light guide plate has a light incident surface, a light exit surface and a reflection surface. The light provided by the light source enters the light guide plate from the light incident surface of the light guide plate, and exits from the light exit surface of the light guide plate. In order to make the light sources passing through the inside of the light guide plate more uniformly mixed, microstructures, such as dot microstructures or strip microstructures, are usually provided on the light emitting surface or reflection surface of the light guide plate. However, generally, the surface with dot-like microstructures has a rough structure, and the light will diffuse after contacting the surface of the structure, so that the direction of the light after refracting out of the light guide plat...
