Latest Patents

Chi-Jui Chang holds a patent for polarizer-free LED displays. This patent describes exemplary subpixel structures that include a directional light-emitting diode structure characterized by a full-width-half-maximum (FWHM) of emitted light having a divergence angle of less than or about 10°. The subpixel structure further includes a lens positioned a first distance from the light-emitting diode structure, where the lens is shaped to focus the emitted light from the light-emitting diode structure. Additionally, the subpixel structure includes a patterned light absorption barrier positioned a second distance from the lens, which defines an opening in the barrier. The focal point of the light focused by the lens is positioned within this opening. These subpixel structures can be incorporated into a pixel structure, and pixel structures may be integrated into a display that is free of a polarizer layer. Chi-Jui Chang has 1 patent to his name.
