    摘要: A display system includes a first die configured to emit light of a first color, a second die configured to emit light of a second color and a third die configured to emit light of a third color. The display system also includes a lens system and an optical waveguide system. The optical waveguide system includes a first grating portion configured to couple in an incident light to the optical waveguide and a second grating portion configured to couple out a transmitting light from the optical waveguide. The first die, the second die and the third die are contained in one package. The lens system is arranged between the package and the optical waveguide system, and is configured to collimate the light of the first color, the light of the second color and the light of the third color onto the first grating portion of the optical waveguide system.

    摘要: A method is provided for optimizing beam shaping of a display comprising an array of light emitting elements, each corresponds to a pixel of said display, in order to adjust angular distribution of light pattern in an optical waveguide. The method comprises the step of simulating a luminance distribution for positional and angular characteristics of luminance of the optical waveguide. The method further comprises the step of measuring a luminance distribution for positional and angular characteristics of luminance of the optical waveguide. The method further comprises the step of comparing the simulated luminance distribution with the measured luminance distribution of the optical waveguide. In addition, the method further comprises the step of defining an optimum emission pattern for every pixel for every color of the display based on the simulated and measured luminance distribution.

    摘要: A system is provided for facilitating an enhanced video pipeline in order to improve color perception. The system comprises a first source configured to generate a first video stream, a second source configured to generate a second video stream, and a computing device. In this context, the computing device is configured to superpose the first video stream onto the second video stream, thereby generating an output video stream. The computing device is further configured to calculate weighting factors for individual pixels or discrete pixel sets of adjacent individual pixels of the output video stream by analyzing the first video stream and/or the second video stream.
