Title:
SYSTEMS AND METHODS FOR MULTIPLYING THE IMAGE RESOLUTION OF A PIXELATED DISPLAY
Document Type and Number:
WIPO Patent Application WO/2019/079350
Kind Code:
A3
Abstract:
Systems integrating display resolution-multiplication solutions can be implemented in a variety of different ways. In many embodiments, the system includes an image projector for projecting image light, an image processor for computing a native image and at least one image shifted in a predefined direction, and at least one switchable grating capable of being switched between diffracting and non-diffracting states. In some embodiments, the switchable grating is optically coupled to the image projector. In a number of embodiments, the switchable gratings have a first configuration for propagating the native image light and at least one other configuration for propagating shifted image light having an angular displacement corresponding to the image shift in a predefined direction. By displaying the native and shifted images sequentially within a human eye integration period, the display resolution can be multiplied.
