  • Patent number: 11956994
    Abstract: The present disclosure is generally related to 3D imaging capable OLED displays. A light field display comprises an array of 3D light field pixels, each of which comprises an array of corrugated OLED pixels, a metasurface layer disposed adjacent to the array of 3D light field pixels, and a plurality of median layers disposed between the metasurface layer and the corrugated OLED pixels. Each of the corrugated OLED pixels comprises primary or non-primary color subpixels, and produces a different view of an image through the median layers to the metasurface to form a 3D image. The corrugated OLED pixels combined with a cavity effect reduce a divergence of emitted light to enable effective beam direction manipulation by the metasurface. The metasurface having a higher refractive index and a smaller filling factor enables the deflection and direction of the emitted light from the corrugated OLED pixels to be well controlled.

  • Publication number: 20240113202
    Abstract: Embodiments of the present disclosure relate to a FinFET device having gate spacers with reduced capacitance and methods for forming the FinFET device. Particularly, the FinFET device according to the present disclosure includes gate spacers formed by two or more depositions. The gate spacers are formed by depositing first and second materials at different times of processing to reduce parasitic capacitance between gate structures and contacts introduced after epitaxy growth of source/drain regions.

  • Patent number: 10056417
    Abstract: An image-sensor structure is provided. The image-sensor structure includes a substrate with a plurality of photoelectric conversion units formed therein, a plurality of color filters formed above the substrate, wherein the color filters are divided into red color filters, green color filters and blue color filters, a plurality of microlenses correspondingly formed above the color filters, a transparent material layer formed above the microlenses, a first filter blocking infrared (IR) light formed above the transparent material layer, a second filter allowing transmission of visible light formed above the first filter, and a lens module formed above the second filter.

  • Patent number: 8593561
    Abstract: A method and system for facilitating focusing of a camera module are disclosed. The camera module includes an image sensor, a lens cube, a barrel and an adjustable member. An adjustable member can be configured to fine-tune the focal length with respect to an image sensor, so that a lens cube with a shorter or longer focal length can be corrected and integrated into the camera module.
