The Classification of Light Guide Plate

The Classification of Light Guide Plate

Light guide plates can be classified by the shape, the production methods, the functions and so on.  So far, there is no uniform classification.

1.Light guide plates could be divided into flat light guide plates and wedge light guide plates according to the shape.

Flat light guide plate is that the light entrance looks like a rectangular.

Wedge light guide plate is that the light entrance looks like a triangular which one side is thick and one side is thin.

2.Light guide plates could be divided into edge light guide plates and bottom light guide plates according to the light lattice production methods.

Printed light guide plate is that light guide lattice points are printed onto the back side of light guide plate. And it is divided into IR printed light guide plate and UR printed light guide plate.

Non-printed light guide plate is that light guide lattice points take shape while light guide plate is formed. And it is divided into chemical etching, precision machinery characterization method (V-cut), photolithography (Stamper) and internal diffusion.

3.Light guide plates could be divided into edge light guide plates and bottom light guide plates according to the light source position (such as LED lamps).

Edge light guide plate is that light source places at the edge side of light guide plate.

Bottom light guide plate is that light source places at the bottom side of light guide plate.

4.Light guide plates could be divided into injection molding light guide plates and cut forming light guide plates according to the production methods.

Injection molding light guide plate is that optical PMMA particles are injected into high temperature and high pressure injection molding machine and cooled into shape.

Cutting Forming light guide plate is that original board of optical PMMA is cut into various shapes.
