Embodiment Construction
[0025] The present invention will be further described below in conjunction with accompanying drawing.
[0026] figure 2 A backlight module 10 according to an embodiment of the present invention is shown. The backlight module 10 includes a light guide plate 11 and an optical film 12 disposed on the light guide plate 11 .
[0027] Such as image 3 As shown, the light guide plate 11 includes a transparent plate 13 and a frame strip 16 integrally formed with the transparent plate 13 . The transparent plate 13 is usually made of a transparent material with a relatively high refractive index. The transparent material may be optical grade polymethyl methacrylate. The transparent plate 13 is a substantially rectangular plate-like structure. One surface of the transparent plate 13 , that is, the first surface 14 is formed as the light-emitting surface; the other surface, that is, the surface opposite to the first surface 14 is the second surface 15 . Except for the second plate...

The invention relates to a light guide plate, a manufacturing method for the light guide plate and a backlight module. The light guide plate comprises a transparent plate and a frame strip which is arranged on the side of the transparent plate, extends in parallel with the side and is formed integrally with the transparent plate. One side of the frame strip close to the light emitting face of the transparent plate protrudes from the plane of the light emitting face to form a first retaining wall for locating optical film. The backlight module comprises the light guide plate. When the optical film is assembled on the light guide plate, the first retaining wall can be used for locating the optical film, and accordingly, a rubber frame can be omitted. Meanwhile, the frame strip is integrated with the transparent plate, the frame strip wall thickness can be small and can be smaller than the wall thickness (0.8mm) of the rubber frame in the background technology, and the problem that the frame strip is not easy to assemble is prevented.
Description
technical field [0001] The invention relates to a liquid crystal display technology, in particular to a light guide plate, a manufacturing method thereof, and a backlight module. Background technique [0002] figure 1 A conventional liquid crystal panel is shown. The liquid crystal panel includes a backlight module and a liquid crystal screen 1 pasted on the backlight module. The backlight module is used as a light source for the liquid crystal panel. The liquid crystal screen 1 displays graphics and colors by modulating the light emitted by the backlight module. [0003] The backlight module includes a light guide plate 2 , a light bar 5 , a plastic frame 3 , a reflector 8 , an optical film 7 and a back plate 4 . exist figure 1 Among them, the right side of the light guide plate 2 is the light incident surface, and the upward surface of the light guide plate is the light output surface. A light emitting element (not shown) is arranged on the light bar 5, and the light...
