Abstract
A time-division multiplexed projection display is pixel shifted to produce an increased perceived display resolution. A polarizing beam splitter (PBS) divides input unpolarized display light into two orthogonal linear polarizations and directs them to two PBS arms. The PBS arms act to shift the light in synchronization with the time-multiplexed display such that a single pixel of the light engine providing the display light is converted into two or four virtual pixels, effectively increasing the perceived display resolution relative to the native resolution of the light engine. The PBS combines the light from both PBS arms into a single, unpolarized output that may then be projected into a lens or a waveguide incoupler to enable the light to propagate through a waveguide for display at a user's eye.
