Latest Patents
Jiann Yu holds a patent for a light-emitting diode with a thick transparent layer. This invention includes a light generation region situated on a light-absorbing substrate. The thick transparent layer ensures that an increased amount of light is emitted from the sides of the LED while minimizing light absorption by the substrate. The thickness of this layer is determined based on its width and the critical angle at which light is internally reflected. This layer can be positioned above, below, or both above and below the light generation region. Additionally, the materials and fabrication processes used for the thick transparent layer may differ from those of the light generation region. Jiann Yu has 1 patent to his name.
