    Abstract: An electronic device such as a head-mounted display may have a display system that produces images. The display system may have one or more pixel arrays (26-1, 26-2) such as liquid-crystal-on-silicon pixel arrays. Images from the display system may be coupled into a waveguide (116) by an input coupler system (114X, 114Y) and may be coupled out of the waveguide in multiple image planes using an output coupler system (120X, 120Y). The input and output coupler systems may include single couplers, stacks of couplers, and tiled arrays of couplers. Multiplexing techniques such as wavelength multiplexing, polarization multiplexing, time-division multiplexing, multiplexing with image light having different ranges of angular orientations, and/or tunable lens techniques may be used to present images to a user in multiple image planes.

    Abstract: An electronic device may include a display system for presenting images close to a user's eyes. The display system may include a display unit that directs light and an optical system that redirects the light from the display unit towards a user's eyes. The optical system may include an input coupler and an output coupler formed on a waveguide. The input coupler may redirect light from the display unit so that it propagates in the waveguide towards the output coupler. The output coupler may redirect the light from the input coupler so that it exits the waveguide towards the user's eyes. A light-redirecting element may be used to redirect edge light that would otherwise be outside of the user' s field of view towards the user's eyes.

    Abstract translation: 电子设备可以包括用于呈现靠近用户眼睛的图像的显示系统。 显示系统可以包括指示光的显示单元和将来自显示单元的光重定向到用户的眼睛的光学系统。 该光学系统可以包括形成在波导上的输入耦合器和输出耦合器。 输入耦合器可以重定向来自显示单元的光，使得其在波导中朝向输出耦合器传播。 输出耦合器可以重定向来自输入耦合器的光，使其从输出耦合器向用户的眼睛射出。 光重定向元件可用于重定向边缘光线，否则这些边缘光线将在用户的视野之外朝向用户的眼睛。
