Abstract: A backlight module with a non-planar lateral structure and LCD apparatus using the same are described. The backlight module comprises a light source; and a light guide body comprising a lateral incident surface and a non-planar lateral structure adjacent to the emitting surface and the bottom surface therebetween; wherein the non-planar lateral structure is opposite lateral incident surface, and a first incident light and a second incident light pass through the lateral incident surface and enter the light guide body; and wherein the non-planar lateral structure reflects and refracts the first incident light so that the reflected and refracted light of the first incident light returns from the non-planar lateral structure back to the light guide body, and the returned first incident light and the second incident light are reflected again from the bottom surface and emitted from the emitting surface to an LCD panel.

Abstract: The present invention provides square seal, a manufacture method of square seal and a manufacture method of a backlight module. The square seal utilizes the roulette design. As being assembled, the redundant material outside the roulette is removed along the roulette to obtain the square seal of narrow frame so that the square seal achieves the narrow frame without the issues of overflow seal and waste material adhesion. The square seal can be easily separated from the waste material to effectively reduce the defect rate. In the manufacture method of the square seal according to the present invention, the square seal inner frame line is first cut on the seal body film material, and then the dotted roulette is formed at position of the square seal outer frame line is pre formed, and finally, the circle of the square seal reserved outer frame line is cut at the periphery of the roulette.

Abstract: A backlight module includes a mold frame, a light guide board, an optic film, a light source, and a heat dissipative sheet. The light guide board has a light incident surface and a light exit surface that is arranged adjacent to the light incident surface. The light source is arranged opposite to the light incident surface of the light guide board. The optic film is attached to the light exit surface. The light source and the light guide board are mounted inside the mold frame. The light source is fixed by a double-sided adhesive tape to the mold frame. The heat dissipative sheet is attached to a surface of the double-sided adhesive tape that is opposite to the mold frame and a projection of the light source is cast to the heat dissipative sheet. A liquid crystal panel and a display screen are also provided.
