Abstract
The invention provides a light guide plate. The light guide plate comprises a light incident surface and a light exit surface adjacent to the light incident surface. The light exit surface is provided with a plurality of straight strip microstructures which are parallel mutually. Each straight strip microstructure extends along a direction vertical to the light incident surface. The plurality of straight strip microstructures are non-periodically distributed in a light-mixing region of the light exit surface adjacent to the light incident surface. In the light guide plate, the plurality of straight strip microstructures are non-periodically distributed in the light-mixing region, so that different regions of the light exit surface have different light exit capacities.
Description
Technical field
The present invention relates to a kind of light guide plate, particularly a kind of different blocks has the light guide plate of different bright dipping abilities.
Background technology
Fig. 1 is traditional light conducting plate structure schematic diagram.The straight list structure that be periodic distribution of the multiple microstructures 200 that arrange on tradition light guide plate exiting surface for being parallel to each other, therefore, on traditional light guide plate exiting surface, the bright dipping ability of each block is identical.But be necessary in some cases to provide a kind of different light guide plate of bright dipping ability of different blocks.
Summary of the invention
In view of this, the invention provides a kind of different blocks and have the light guide plate of different bright dipping abilities.
This light guide plate comprises incidence surface and the exiting surface adjacent with this incidence surface, on this exiting surface, be provided with multiple vertical bar shape microstructures, the plurality of vertical bar shape microstructure is parallel to each other, the spacing of adjacent two vertical bar shape microstructures is identical, and each vertical bar shape microstructure is extended along the direction of vertical this incidence surface, and the plurality of microstructure is non-periodic distribution in the mixed light region of contiguous this incidence surface of this exiting surface.
In the present invention, because multiple microstructures are non-periodic distribution in mixed light region, thereby cause different blocks on exiting surface to there is different bright dipping abilities.
Accompanying drawing explanation
Fig. 1 is the structural representation of traditional light guide plate.
Fig. 2 is the structural representation of the light guide plate in present embodiment.

Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Please refer to Fig. 2, the light guide plate 100 in present embodiment comprises incidence surface 10, exiting surface 20 and is arranged on the multiple microstructures 30 on exiting surface 20.Incidence surface 10 is a sidewall of this light guide plate 100, and exiting surface 20 is the upper surface of this light guide plate 100.Light source 40 is arranged on the sidewall of this light guide plate 100, and the light that light source 40 produces is injected this light guide plate 100 from this incidence surface 10.Light source 40 is light emitting diode.On exiting surface 20, the region of contiguous incidence surface 10 is commonly referred to mixed light region, and the light that light source 40 provides needs first to carry out mixed light in mixed light region after entering the sidewall of this light guide plate 100.
In the present embodiment, because multiple microstructures 30 are non-periodic distribution in mixed light region, thereby cause different blocks on exiting surface 20 to there is different bright dipping abilities.
