Abstract:
A display device includes a plurality of pixels. Each pixel includes two or more subpixels. The plurality of pixels includes a first subpixel configured to transmit light of a first color and a second subpixel configured to transmit light of a second color that is distinct from the first color. The display device also includes a beam steering device, and one or more compensators located between the plurality of pixels and the beam steering device and configured to change a direction of the light from the first subpixel and transmit the light toward the beam steering device and change a direction of the light from the second subpixel and transmit the light toward the beam steering device.
