Abstract
The utility model relates to a light guide plate with oblique pyramid design. The light guide plate is composed of two parts: a substrate and oblique pyramids, wherein the oblique pyramids are pasted and fixed on the upper and lower surfaces of the substrate. The oblique pyramids on the upper surface of the substrate are arranged in the way in which the height thereof decreases from the two sides to the middle when the oblique pyramids are seen from the cross-sectional direction; the oblique pyramids on the lower surface of the substrate are arranged in the way in which the height thereof decreases from the middle to the two sides; and the oblique pyramids are irregularly distributed in terms of height when being seen from a direction perpendicular to the cross-sectional direction.
Description
Technical field
The utility model relates to the light guide plate with the design of inclination pyramid, belongs to field of display.
Background technology
Present light guide plate is on the market generally used for LCD display, but ubiquity diffuse reflection deficiency causes the problem of brightness irregularities.
Utility model content
The utility model discloses the light guide plate with the design of inclination pyramid, described light guide plate is comprised of two parts: substrate and inclination pyramid, described inclination pyramid is pasted and is fixed in the upper and lower surface of substrate, inclination pyramid on the upper surface of substrate, its height is looked from cross-sectional direction, from both sides to centre, state tapers off; Inclination pyramid on the lower surface of substrate, its height is from centre to both sides, and state tapers off; Described inclination pyramid is being seen perpendicular to cross-sectional direction, is highly irregular distribution.
The light guide plate with the design of inclination pyramid of the present utility model, brightness is even, is conducive to be applied in the displays such as LCD.
Accompanying drawing explanation
By describing in more detail exemplary embodiment of the present utility model with reference to accompanying drawing, above and other aspect of the present utility model and advantage will become and more be readily clear of, in the accompanying drawings:
Fig. 1 is the theory structure schematic diagram with the light guide plate of inclination pyramid design of the present utility model.
Embodiment
Hereinafter, now with reference to accompanying drawing, the utility model is described more fully, various embodiment shown in the drawings.Yet the utility model can be implemented in many different forms, and should not be interpreted as being confined to embodiment set forth herein.On the contrary, it will be thorough with completely providing these embodiment to make the disclosure, and scope of the present utility model is conveyed to those skilled in the art fully.
