  • Patent number: 11852816
    Abstract: The display may include a display module and a waveguide. The module may produce first light of first wavelengths during first time periods and may produce second light of second wavelengths during second time periods interleaved with the first time periods. Diffractive gratings or a dichroic wedge may redirect the first light into the waveguide at a first angle and may redirect the second light into the waveguide at a second angle separated from the first angle by a separation angle. The separation angle may be equal to half the angle subtended by the projection of a pixel in the module. The first and second time periods may alternate faster than the response of the human eye. This may configure the first and second image light to collectively provide images at an eye box with an increased effective resolution without increasing the space or power consumed by the display module.
