  • Patent number: 11727892
    Abstract: Described is a system including a display, a display controller, and control logic communicatively coupled to the display. The display controller determines, based on coordinates of a focus point on the display, boundaries of a first image region and a second image region in an output image to be rendered. The focus point is determined through tracking an eye movement of a user viewing the display. The first image region has a higher resolution than the second image region. The display controller is configured to send image data together with control signals to the control logic. The control signals cause the control logic to render the output image on the display using the image data. As part of rendering the second image region, the control logic outputs a shared signal onto signal lines that are coupled to light sources in a group of adjacent rows or columns.

  • Publication number: 20230238733
    Abstract: A metal shell-less receptacle connector includes a ceramic module, a glass seal having an insertion hole into which an outer circumferential portion of the ceramic module is fitted, and a ceramic support having a seal fastening hole into which an outer circumferential portion of the glass seal is fitted and fastening holes to which fasteners are fastened. Contacts and a ceramic material are integrated, whereby high data transmission is enabled due to impedance optimization and low loss characteristics, heat dissipation performance is improved due to high thermal conductivity, and durability is improved due to high strength. The shell-less structure reduces frequency interference, thereby improving the performance of an antenna positioned adjacent to the connector. The glass seal improves waterproof performance. The connector is connected to a main board using an FPCB, thereby improving the degree of freedom of position. A simple assembly structure promotes mass production, thereby reducing cost.
