METHOD AND HARDWARE TO ENHANCE LIGHT OUT-COUPLING

摘要

The present invention provides an enhanced light out-coupling device for extraction of light radiation from a light source. The enhanced light out-coupling device comprises a grid having a plurality of channels, a reflective material layer coated on the grid, and a high refractive index fluid layer. In addition, the grid can be filled with phosphor particles for light converting. The device of the presently claimed invention is able to effectively avoid the scattering problem generated from the sapphire substrate and phosphor particles, as well as reduce light adsorption by the array of grid during the light extraction, leading to better image quality.

主权项

1. A light out-coupling device for light traction from at least one light source, comprising:
at least one grid, having one or more channels; and at least one reflective material layer coated on at least a portion of the grid, wherein the at least one of the one or more channels are configured for allowing light from the light source to pass through.
