Abstract
The utility model relates to an inclined LED light guide plate which is composed of two parts: a substrate and light guide pyramids, wherein the light guide pyramids are pasted and fixed on the upper and lower surfaces of the substrate. The light guide 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; the light guide 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. The cross section of the substrate is trapezoidal, namely, the thickness of the substrate gradually decreases from one side to the other side.
Description
Technical field
The utility model relates to tilting LED light guide plate, 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 tilting LED light guide plate, it is comprised of two parts: substrate 1 and leaded light pyramid 2, and described leaded light pyramid 2 is pasted and is fixed in the upper and lower surface of substrate 1, the leaded light pyramid 2 on the upper surface of substrate 1, its height is from both sides to centre, and state tapers off; Leaded light pyramid 2 on the lower surface of substrate 1, its height from centre to both sides, the state that tapers off, the xsect of described substrate is trapezoidal, its thickness is from successively decreasing gradually to another side on one side.
Tilting LED light guide plate 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:
