SYSTEM FOR 3D IMAGE PROJECTIONS AND VIEWING

Shaped glasses have curved surface lenses with spectrally complementary filters disposed thereon. The filters curved surface lenses are configured to compensate for wavelength shifts occurring due to viewing angles and other sources. Complementary images are projected for viewing through projection filters having passbands that pre-shift to compensate for subsequent wavelength shifts. At least one filter may have more than 3 primary passbands. For example, two filters include a first filter having passbands of low blue, high blue, low green, high green, and red, and a second filter having passbands of blue, green, and red. The additional passbands may be utilized to more closely match a color space and white point of a projector in which the filters are used. The shaped glasses and projection filters together may be utilized as a system for projecting and viewing 3D images.

Viewing device adjustment based on eye accommodation in relation to a display

Examples disclosed herein relate to viewing device adjustment based on eye accommodation in relation to a display. In one implementation, a computing device determines accommodation information related to a viewer's focus on an image rendered on a display. The computing device may cause an optical component associated with a viewing device to adjust based on the determined accommodation.

Photoluminescent nanocrystals based color liquid crystal display for switchable two dimensional/three dimensional displays with wider color gamut and high energy efficiency
10955702 · 2021-03-23 · ·

A liquid crystal display (LCD) device containing a layer of patterned photoluminescent nanoparticles, which can emit highly saturated color lights when excited with backlights, is disclosed in this invention. The patterned photoluminescent nanoparticle layer is disposed between the backlight and the liquid crystal. The display device can improve the light utilization efficiency for 3 times thus saving reduce the backlight power consumption to or being 3 times brighter at the same power consumption from conventional LCD displays. The display also can produce an ultra-wide color gamut up to 95% of the CIE 1976 color space or 165% of NTSC color gamut. The display is capable of switching between 2-dimensional and 3-dimensional viewing modes without any hardware structures changes applied.
