  • Patent number: 11120747
    Abstract: A display may have an active area that includes display pixels. The display may include an inactive notch region that extends into the active area. Data lines may provide image data from display driver circuitry to the display pixels. The image data may include data signals that correspond to portions of the display that do not include pixels, such as the inactive notch region. The null data signals may cause nonuniformities in the displayed image. The null data signals may be adjusted to minimize the nonuniformities. Null data signals corresponding to the inactive notch region may be adjusted to have gray levels that gradually decrease with distance from the border between the inactive notch and the active area. All of the data signals corresponding to the inactive notch may be set to a uniform gray level.

  • Publication number: 20210267754
    Abstract: The present invention relates to an aspherical multifocal intraocular lens with large depth of field, the intraocular lens having an anterior optical surface and a posterior optical surface, wherein one optical surface is distributed with an aspherical surface which plays a role of expanding the depth of field, and the other optical surface is distributed with a multifocal structure which plays a role of providing two or more focal points. The aspherical surface provides a depth of field matching with an absolute value of a difference in refractive power of at least one pair of adjacent focal points of the two or more focal points provided by the multifocal structure. The aspherical surface, on the one hand, allows a continuous visual range between the focal points and, on the other hand, extends near vision in the direction of near focal point through the depth of field, thereby enabling continuous, uninterrupted full-range vision and adequate near vision.
