An apparatus including a light source, a first display, a first polarizing beam splitter having a first light input surface, a first light input transmission surface, a first display interface surface, and a first display projection surface, a second display, a second polarizing beam splitter having a second light input surface, a second display interface surface, and a second display projection surface, and a retarder that is positioned between the first light input transmission surface and the second light input surface is disclosed.

Single light source near eye display

An apparatus including a light source configured to output unpixelated light; an array of reflective pixel control elements configured to selectively reflect incident unpixelated light to produce first pixelated light defining first display content; a pixelated display configured to produce second pixelated light defining second display content; and an optical arrangement configured to direct unpixelated light from the light source to the array of reflective pixel control elements and to combine the pixelated light defining the first display content and the second pixelated light defining the second display content to provide, as an output, third pixelated light defining third display content.

Display apparatus

A method including forming a substrate to form a template which includes areas of high relief and areas of low relief; and forming a high refractive index diffraction grating in the template by adding high refractive index material to the template to form a continuous low relief surface. The high refractive index material fills the areas of low relief and covers the areas of high relief of the template to form a high refractive index diffraction grating. The high refractive index diffraction grating includes the high refractive index material configured to have a low relief side corresponding to the continuous low relief surface and configured by the template to have a periodic side including areas of high relief and areas of low relief which periodically alternate in the first direction with the first periodicity and are interconnected by the high refractive index material.

Compound diffraction grating and method of manufacture

A method including, in a standard display mode, causing display of a graphical element at a position on a see through display that includes a light projection display that overlays a light filtration array such that the light projection display projects the graphical element at the position on the see through display and the light filtration array filters ambient light at the position on the see through display, transitioning from the standard display mode to a low power display mode, causing termination of display of the graphical element on the see through display based on the low power display mode, determining that an event has occurred, generating a notification that signifies the event, and causing actuation of the light filtration array such that a plurality of light filtration cells of the light filtration array are selectively actuated in a pattern that depicts the notification is disclosed.

Control of selective actuation of a light filter array

An apparatus including a light source; a pixel control element; and an input transmission polarizer configured to: polarize incident light from the light source into transmitted first and second light portions, wherein the first light portion has a first polarization and the second light portion has a second polarization and wherein the first and second polarizations are orthogonal; to provide the first light portion as input to the pixel control element; and to output the second light portion to provide the second light portion for illumination.
