Description

Light guide plate combined structure

Technical Field

The utility model relates to a light guide plate integrated configuration belongs to light guide plate technical field.

Background

Traditional light guide plate backlight unit is white backlight, and in addition a plurality of mini colored LED, but the backlight can only send white halo, and the mini LED can send colored halo in a poor light, but the mode of giving out light sends the colour through colored LED, and foretell backlight unit structure has increased manufacturing cost to a plurality of colored LED have also caused the equipment inconvenient.

Disclosure of Invention

The utility model discloses the technical problem that will solve lies in: the utility model provides a light guide plate integrated configuration, it has solved traditional backlight unit and has increased manufacturing cost to the inconvenient problem of equipment.

The utility model discloses the technical problem that will solve takes following technical scheme to realize:

the light guide plate combined structure sequentially comprises a light guide plate base material, a mesh point layer and a printing layer, wherein the mesh point layer and the printing layer are arranged on all or part of the light guide plate base material, and the printing layer is printed by color ink.

As a preferred example, the thickness of the light guide plate substrate is 0.1mm to 0.5mm.

As a preferred example, the thickness of the printed layer is 0.008mm to 0.04mm.

As a preferred example, the area of the dot layer is 0.5% -100% of the area of the base material of the light guide plate.

The utility model has the advantages that:

1. the utility model discloses increased the site surface printing layer, can print or attach various colours, white backlight sees through the color printing ink on printing layer, and the brilliant awn that can shine out needs lets the leaded light become gorgeous and colorful, adopts this kind of structure need not use multiple colored LED light source, has cost-effective, assembles convenient advantage.

2. The utility model discloses a color ink printing perhaps attaches on the site layer, for printing or attach on the light guide plate base material, according to attaching different colours, luminance increases 10% -70%.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a partial structural schematic diagram of a cross-sectional view of the present invention.

In the figure: the light guide plate comprises a light guide plate base material 1, a dot layer 2 and a printing layer 3.

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.

As shown in fig. 1-2, the light guide plate combination structure sequentially includes a light guide plate substrate 1, a dot layer 2 and a printing layer 3, specifically, the dot layer 2 is formed by hot pressing (or cold pressing) the light guide plate substrate 1 with a mold, the printing layer 3 is a color ink, and is directly printed or attached below the dot layer 2, i.e., on one side away from the light guide plate substrate 1, in some embodiments, the dot layer 2 and the printing layer 3 are only arranged on all or part of the area of the light guide plate substrate 1, specifically, the area of the dot layer 2 is 0.5% -100% of the area of the light guide plate substrate 1, and dots and printing are arranged according to the place where the light guide plate needs to emit light.

In some designs of the light guide plate combination structure, the thickness of the light guide plate substrate 1 can be 0.1mm-0.5mm, the thickness of the printing layer 3 can be 0.008mm-0.04mm, and different light emitting brightness can be obtained by changing the thickness of the printing layer 3 without increasing or decreasing or controlling the power of the light emitting source.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and such changes and modifications fall within the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
