  • Patent number: 11927628
    Abstract: The present disclosure provides a semiconductor wafer. The semiconductor wafer includes: a scribe line between a first row of dies and a second row of dies; and a benchmark circuit disposed adjacent to the scribe line and electrically coupled to a first conductive contact and a second conductive contact. The benchmark circuit includes a first device-under-test (DUT); a second DUT; a first switching circuit configured to selectively couple the first DUT and the second DUT to the first conductive contact; and a second switching circuit configured to selectively couple the first DUT and the second DUT to the second conductive contact.

  • Patent number: 7728938
    Abstract: Disclosed is a liquid crystal display mainly including a liquid crystal layer having negative dielectric anisotropy sandwiched between two substrates treated by vertical alignment process, and first and second domain regulators for regulating orientation of the liquid crystal layer such that the liquid crystal molecules are aligned obliquely when a voltage is applied, so that the orientation will include a plurality of first and second directions. The first directions are different from the second directions. Each pixel is provided with one of the first and second domain regulators in a manner that every two adjacent pixels or every two adjacent R pixels, two adjacent G pixels or two adjacent B pixels are provided with different domain regulators.

  • Publication number: 20070195027
    Abstract: A display method capable of displaying motion images includes displaying a first image, displaying a white or a gray image after displaying the first image, and displaying a second image subsequent to the first image after displaying the white image or the gray image using a liquid display panel. The method improves the display quality of moving images and the visual brightness of the liquid display panel by inserting white or gray images in order to reduce the frame delay of the liquid display panel.
