Patents by Inventor Jia Yuan ZHANG

Jia Yuan ZHANG has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Mobile device and optical imaging lens thereof
    Patent number: 10025068
    Abstract: Present embodiments provide for mobile devices and optical imaging lens thereof. Optical imaging lens may comprise an aperture stop and six lens elements positioned sequentially from an object side to an image side. Through controlling the convex or concave shape of the surfaces of the lens elements and designing parameters satisfying at least one inequality, the optical imaging lens may exhibit better optical characteristics and the total length of the optical imaging lens may be shortened.
    Type: Grant
    Filed: April 24, 2015
    Date of Patent: July 17, 2018
    Assignee: GENIUS ELECTRONIC OPTICAL (XIAMEN) CO., LTD.

  • Imaging lens
    Patent number: 9971124
    Abstract: An imaging lens including a first lens element, an aperture stop, a second lens element, a third lens element, a fourth lens element and a fifth lens element arranged in sequence from an object side to an image side along an optical axis is provided. Each of the first to the fifth lens elements has an object-side surface and an image-side surface. The first lens element has positive refractive power. The second lens element has refractive power. The third lens element has positive refractive power. The object-side surface of the third lens element has a concave portion in a vicinity of the optical axis. The fourth lens element has negative refractive power. The image-side surface of the fourth lens element has a convex portion in the vicinity of the optical axis. The fifth lens element has refractive power.
