  • Publication number: 20240118660
    Abstract: Embodiments of this application provide example holographic recording media, holographic polymer materials, methods for preparing holographic polymer materials, and display devices. An example holographic recording medium includes a first-order crosslinked network, a photoinitiator, and a second-order monomer. The first-order crosslinked network provides a mechanical support for the holographic recording medium. The second-order monomer includes a monomer with a free radical reactivity. The photoinitiator is used to initiate polymerization of the second-order monomer. The holographic recording medium includes at least one of an ester group (I), a urethane group (II), a carbamido group (III), an allophanate group (IV), or an amide group (V). Groups linked to the ester group (I), the urethane group (II), the carbamido group (III), the allophanate group (IV), and the amide group (V) are separately selected from at least one of the following: alkyl, alkoxy, alkenyl, or aryl.

  • Publication number: 20240094531
    Abstract: A projection system is provided, and includes: a phase compensation apparatus (101), configured to perform first phase compensation and chromatic aberration correction on a light ray of a received image, and reflect an output light ray of the image to a holographic combiner (102); and the holographic combiner (102), configured to perform second phase compensation on the light ray that is of the image and that is output by the phase compensation apparatus (101). The phase compensation apparatus (101) is utilized to correct at least one of the following aberrations: astigmatism, a spherical aberration, and a coma aberration; and further correct another aberration in combination with the holographic combiner (102), thereby effectively eliminating aberrations and improving imaging quality. The projection system is used in a head-up display system, an augmented reality display system, a head-mounted display device, and the like.

  • Patent number: 11893149
    Abstract: Provided are systems, compositions and methods that useful in any setting where generating and tracking light is used. The systems, methods and compositions contain as a component flexible, transparent membrane-based materials that include light emitting diodes (LEDs). The LEDs can include or be formed from colloidal quantum dots (CQDs) as an active layer. The CQDs can be formed from solution-processed semiconductor nanocrystals. They have a tunable band gap energy that can be readily tuned by adjusting the size of the nanocrystals. Transparent membrane-based LED arrays exhibit emission wavelength that can be tuned anywhere in the range of 800-2000 nm. The LEDs are highly transparent in the visible wavelength range with the exception of the CQD active layer. The CQD-based LEDs are components of any device or system wherein generating and/or tracking reflected light is utilized, such as in tracing the location and movement of a living individual, or an inanimate object.

  • Publication number: 20230119967
    Abstract: A non-imaging optical concentrator, including a top portion, a body, and a bottom portion, wherein the top portion is configured to receive an incident light and transmit the received incident light to the body when the incident light is within an angle of acceptance for the non-imaging optical concentrator, and where the body is configured to reflect the incident light transmitted by the top portion to the bottom portion when the incident light is within the angle of acceptance for the non-imaging optical concentrator, and wherein the top portion is configured to split or diverge the incident light into two or more directions when the incident light is within the angle of acceptance for the non-imaging optical concentrator.
