  • Publication number: 20240120317
    Abstract: A fan-out semiconductor device includes stacked semiconductor dies having die bond pads arranged in columns exposed at a sidewall of the stacked semiconductor dies. The stacked dies are encapsulated in a photo imageable dielectric (PID) material, which is developed to form through-hole cavities that expose the columns of bond pads of each die at the sidewall. The through-hole cavities are plated or filled with an electrical conductor to form conductive through-holes coupling die bond pads within the columns to each other.

  • Patent number: 11929041
    Abstract: A display apparatus includes a backlight module with backlight zones, a panel over the backlight module, and a circuit configured to generate compensated pixel data for the panel based on image data and an arrangement of the zones of the backlight module, in which the image data has image areas respectively corresponding to the backlight zones. For a first image area being a low-luminance image area and a luminance intensity of a first zone of the zones corresponding to the first image area being less than a luminance intensity of a second zone corresponding to a second image area neighboring the first image area, the circuit performs first pixel compensation for high-luminance pixels in the second image area and second pixel compensation on low-luminance pixels in the second image area, in which the second pixel compensation is greater than the first pixel compensation.
