20100079865 | Near-to-eye scanning display with exit-pupil expansion - The specification and drawings present a new apparatus and method for near-to-eye (e.g., retinal) displaying with exit-pupil expansion using a scanning component (e.g., a scanning mirror) and an exit-pupil expander (e.g., diffractive exit-pupil expander) for providing a retinal scanning display with a large exit pupil. | 04-01-2010 |
20100295792 | OPTICAL ACTUATORS IN KEYPADS - The specification and drawings present a new apparatus and manufacturing method for optical protrusions (e.g., dome pins or actuators) attached to a light guide for providing backlight, actuation function and/or tactile feedback in keypad modules of electronic devices. Spatially and spectrally selective out-coupling of light from the light guide (e.g., a planar light guide plate) can be accomplished using these optical actuators integrated with the light guide for keypad illumination to control out-coupling efficiency and/or spectra of the out-coupled light to enable modification of the visual appearance (intensity, colored/white) of individual keys of the keypad. | 11-25-2010 |
20100296163 | Exit Pupil Expanders with Wide Field-of-View - The specification and drawings present a new apparatus and method for providing a wide field-of-view as well as illumination uniformity in exit pupil expanders (EPE) using stacked EPE substrates (or plates) with non-symmetric exit pupil expansion that use a plurality of diffractive elements for expanding the exit pupil of a display for viewing. | 11-25-2010 |
20100315719 | Exit Pupil Expanders with Spherical and Aspheric Substrates - The specification and drawings present a new apparatus and method for using exit pupil expanders (EPE) with spherical or aspheric non-flat substrates and a plurality of diffractive elements for expanding the exit pupil of a display for viewing in order to reduce image spreading. This can also enable improved image resolution and utilization of shorter focus distances. | 12-16-2010 |
20100321781 | DEVICE FOR EXPANDING AN EXIT PUPIL IN TWO DIMENSIONS - A diffractive beam expander ( | 12-23-2010 |
20100328794 | OPTICAL APPARATUS AND METHOD - An apparatus and a method are provided. The apparatus including: a light expander configured to expand light, input into the light expander, in a first dimension, and configured to provide diverging light that diverges in the first dimension; and an optical device configured to redirect diverging light, received from the light expander, to produce converging light that converges in the first dimension. | 12-30-2010 |
20110002143 | LIGHT GUIDE PLATE AND A METHOD OF MANUFACTURING THEREOF - A light guide plate ( | 01-06-2011 |
20130314789 | Optical Apparatus and Method for Expanding an Exit Pupil - A first optical arrangement is configured to couple into an apparatus a first component of a light beam having a wavelength within a first spectral range; a second optical arrangement configured to couple a second component of the light beam having a wavelength within a different second spectral range; a third optical arrangement configured to expand the first component in a first dimension to create an expanded first component; a fourth optical arrangement configured to expand, in a second dimension, the expanded first component to create a further expanded first component, and to output the further expanded first component; a fifth optical arrangement configured to expand the second component in the second dimension to create an expanded second component; and a sixth optical arrangement configured to expand, in the first dimension, the expanded second component to create a further expanded second component, and to output the further expanded second component. | 11-28-2013 |
20140009833 | Lens with an Out-Coupling Element - A lens including: a central refracting portion and a peripheral portion configured to support the lens in a lens mount wherein the peripheral portion has a surface including at least one out-coupling element configured to couple light out of the lens. | 01-09-2014 |
