  • Publication number: 20250374835
    Abstract: Some implementations described herein include a semiconductor device. The semiconductor device includes a radio frequency switch structure including a phase change material layer and a heat spreader component. A form factor and a location of the heat spreader component improves a uniformity of heat distribution within the radio frequency switch structure relative to other heat spreader components having different form factors and/or locations. Additionally, the phase change material layer includes a concentration of germanium and tellurium that reduces a resistivity of the radio frequency switch structure relative to other concentrations.

  • Patent number: 10996523
    Abstract: A display device is provided. The display device includes a display module and an antenna coil. The display panel has a first substrate, a second substrate, a common electrode layer, a TFT layer and a light modulating layer. The common electrode layer is disposed between the first substrate and the second substrate. The antenna coil is disposed on the side of the first substrate or the second substrate facing away from the light modulating layer. The orthogonal projection of the antenna coil on the light common electrode defines a contour of the antenna coil, wherein the common electrode layer is discontinuous along at least one part of the contour.

  • Publication number: 20120317171
    Abstract: An Internet-based system and application includes both a server and a plurality of client hardware platforms for executing the server as well as the client software. The current invention provides both bottom-up and top-down approaches in modeling information while all other existing systems provide only bottom-up approach. The system and application provide a set of pre-build widgets, also called “molecules”, that spare users from the details and complexity of the underlying web technologies while allowing them to build end applications from intermediary components called droplets by simply assembling and connecting existing molecules. Droplets are stored in a centralized repository wherein all other droplets that have been previously created by this user or others are also stored. Droplets can be selectively shared with others by assigning read/write privileges on creation or on the fly. Multiple droplets can be saved as a single HTML file called a formation.

  • Patent number: 7880856
    Abstract: A pixel unit including a pixel electrode, a scan electrode, a common voltage electrode, a data electrode and at least one redundancy electrode is provided. During the fabricating process of the pixel unit, if a particle is simultaneously located between any two of the pixel electrode, the scan electrode and the common voltage electrode, it would cause a short circuit between the two electrodes. The pixel unit can generate a cross-shaped defect signal at the location where a short circuit happens when the pixel unit undergoes an array test or a cell test. The user can thereby quickly locate the defect and repair it.
