LGF Plate-to-plate Manufacturing Method and Structure Thereof

A LGP plate-to-plate manufacturing method comprising the steps of:

• preparing an optical substrate with a first surface and a second surface;
• mechanically extruding a first integrated microstructure on the first surface of the optical substrate;
• coating an optical layer on the first surface of the optical substrate;
• and
• curing the optical layer to directly form a second microstructure on the first surface of the optical substrate.

A light guide plate structure comprising:

• an optical substrate provided with a first surface and a second surface;
• a first integrated microstructure mechanically extruded on the first surface of the optical substrate such that the first integrated microstructure and the optical substrate are combined in a single layer;
• an optical layer coated on the first surface or the second surface of the optical substrate;
• a second microstructure formed by curing the optical layer.
