Embodiment Construction

[0025] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0026] The invention provides a light guide plate, which has a special optical structure and can eliminate bright lines generated between two spliced ​​light guide plates.

[0027] The present invention provides a backlight module, which can provide a uniform surface light source by using the above-mentioned light guide plate.

[0028] The invention provides a light transmission method, which can provide a uniform surface light source by using the above-mentioned light guide plate.

[0029] The invention provides a light guide plate, which has an upper surface and a lower surface. The light guide plate has a plurality of light guide regions, and each light guide region has a first side and a second side adjacent to each other. A light source is provided at the first side, and the light source provides light incident into the light guide plate....

Abstract

The invention relates to a light guide plate, a backlight module and a light transmission method. The light guide plate is provided with an upper surface, a lower surface and a plurality of light guide zones, each light guide zone is provided with a first edge and a second edge which are adjacent to each other, the first edges are provided with light sources for providing light incident upon the light guide plate, and the transmission direction of the light is parallel to the extension direction of the second edges. The light guide plate also comprises a plurality of strip-shaped bulges which are arranged at least one of the upper surface and the lower surface of the light guide plate along the extension direction of the second edge; and the light can be transmitted in the strip-shaped bulges. The invention has the advantage of eliminating bright rays generated between two spliced light guide plates.

Description

technical field [0001] The invention relates to a backlight module, in particular to the structure of a light guide plate in the backlight module and a light transmission method using the light guide plate. Background technique [0002] The liquid crystal display includes a liquid crystal display panel and a backlight module. With the development trend of light and thin liquid crystal displays, a thinner side-illuminated backlight module is gradually adopted, which is roughly composed of a light emitting diode (Light Emitting Diode, LED) and a light guide plate. [0003] The light guide plate is an optical component with high optical precision. In order to convert the line light source emitted from the LED into a uniform surface light source through the light guide plate, a light scattering pattern is usually provided on the light emitting surface of the light guide plate, and the light scattering pattern is in a continuously changing form. [0004] However, when there is ...
