[0064] see figure 1 and figure 2 shown, where figure 1 is a three-dimensional schematic diagram of one of the viewing angles, figure 2It is a three-dimensional schematic diagram of another viewing angle. As can be seen from the above figures, the first embodiment of the present invention provides a light guide plate P, which includes: a light guide body 1, a first light guide unit 2 and a second light guide unit 3, wherein the light guide body 1 has A first surface 100 , a second surface 101 opposite to the first surface 100 , and a light incident surface 102 connected between the first surface 100 and the second surface 101 . Furthermore, according to different design requirements, the first surface 100 and the second surface 101 can be respectively a reflective surface and a light-emitting surface, or reversed, and the first surface 100 and the second surface 101 can be respectively a light-emitting surface and a reflective surface. noodle. In addition, according to d...

[0087] see Figure 9 As shown, the third embodiment of the present invention provides a display device, which includes: a light guide plate P, a light emitting structure B and a display panel D. As shown in FIG. Wherein, the light emitting structure B is adjacent to the light incident surface 102 , and the projected light beam L1 generated by the light emitting structure B can enter the light guide body 1 from the light incident surface 102 . In addition, the display panel D is disposed above the light guide plate P, and the projected light beam L1 can pass through the light guide plate P to form a surface light source directed toward the display panel D. Referring to FIG. For example, when the first surface 100 and the second surface 101 are the reflection surface and the light exit surface respectively, the projected light beam L1 entering the light guide body 102 from the light incident surface 102 can be reflected by the first light guide unit 2 to form The light beam L2 ...

Abstract

A light guiding plate includes a light guiding main body, a first light guiding unit and a second light guiding unit. The light guiding main body has a first surface, a second surface opposite to the first surface and a light inlet face connecting between the first and second surfaces. The first light guiding unit includes first and second light guiding structures disposed on the first surface. The first and second light guiding structures are parallel aligned, each second light guiding structure has a plurality of first light guiding bodies that is individually separating and connecting the immediately abreast first light structures, and the arrangement density of the plurality of first light guiding bodies decreases toward the light inlet face. The second light guiding unit includes a plurality of third light guiding structures disposed on the second surface. The third light guiding structures are parallel arranged.

Description

technical field [0001] The invention relates to a light guide plate, a backlight module and a display device, in particular to a light guide plate designed with a multi-dimensional structure, and a backlight module and a display device using the light guide plate. Background technique [0002] The display panel of a liquid crystal display (LCD) itself does not have luminous characteristics, and must rely on the light source provided by the backlight module (Backlight module) to achieve the display function. The brightness, efficiency, and color rendering provided by the backlight module will affect the performance of the display. Therefore, the development of backlight modules with high brightness and high quality is currently the focus of development. [0003] Generally speaking, a backlight module is mainly composed of a light source, a light guide plate, a reflector plate, a diffuser plate and a prism plate. The light source can be arranged on one side or two opposite si...
