Embodiment Construction

[0016] Please refer to FIG. 2 and FIG. 3 together, which are a perspective view and a cross-sectional view of the first embodiment of the light guide plate of the present invention, respectively. The light guide plate 2 includes a transparent plastic substrate 21 and a metal sheet 20 coated with a reflective film 22 on its upper surface. One surface of the metal sheet 20 is uniformly provided with a plurality of cylindrical microholes 201 of the same size, and the transparent plastic substrate 21 includes at least one light incident surface 211, a bottom surface 212 perpendicular to the light incident surface 211 and a bottom surface 212 The opposite light-emitting surface 213 . Part of the material of the transparent plastic substrate 21 is filled into the micropores 201 on the surface of the metal sheet 20 , so that the bottom surface 212 is tightly combined with the surface of the metal sheet 20 having the micropores 201 .

[0017] In the above structure, the metal sheet 2...

Abstract

The invention discloses a light leading board, it includes a transparent basis material and a metal chip, the transparent basis material includes at least one light inputting side, one base side and one light outputting side, the light inputting side is used to accept incident rays from lamp-house, the base side is used to scatter, reflect incident rays, the light outputting side is used to lead out the scattered and reflected rays. The metal chip has tiny holes on one side, the transparent basis material has microdots matching to the holes, and be combined with the tiny holes tightly. The invention also discloses a producing method of above light leading board.

Description

【Technical field】 [0001] The invention relates to a light guide plate and a manufacturing method thereof, in particular to a light guide plate for a liquid crystal display device and a manufacturing method thereof. 【Background technique】 [0002] Liquid crystal display is a kind of non-self-luminous display device, and its display is mainly realized by controlling the passage or non-passage of the light beam emitted by the external light source, so it needs a corresponding backlight module or front light module, which can turn the external light source The emitted light beam guides the display panel to realize the display function, and the light guide plate is an important part of the backlight module. [0003] Please refer to FIG. 1 , which is a light guide plate 10 in the prior art. The light guide plate 10 is made of a transparent plastic substrate 103 . The light-emitting surface 1033 of the light guide plate 10 is evenly distributed with prism structures 101 , and the b...
