  • Patent number: 11881146
    Abstract: A backlight module and display device, related to the display field. The backlight module includes a plurality of light-emitting elements and a controller, where the plurality of light-emitting elements serve as light sources for a plurality of sub-pixels respectively; and the controller is configured to control a brightness of each of the plurality of light-emitting elements. When the backlight module is in operation, if an i-th data line does not need to charge one of a plurality of sub-pixels connected to the i-th data line, the controller increases the brightness of the light-emitting element corresponding to a next sub-pixel when the next sub-pixel emits light.

  • Patent number: 11880456
    Abstract: A method in one embodiment creates a model of an authentic IC for use in comparisons with counterfeit ICs. The model can be created by determining a first or initial set of points of interest (POIs) on the simulated physical (e.g., gate level) layout and simulating side channel leakage from each POI and then expanding the size of the POI and repeating the simulation and comparing successive simulation results (between successive sizes of POIs for a given POI) to determine if a solution for the size of the POI has converged. The final POIs are then processed in a simulation that can use multiple payloads (e.g., cryptographic data) over the entire set of final POIs, and the resulting data set can be used to create the model.

  • Patent number: 11881683
    Abstract: A semiconductor device fabrication method in which a growing process is followed by a capping process in which a phosphor containing material cap layer is deposited over a final GaAs based layer. The wafer, containing many such substrates, can be removed from the reaction chamber to continue processing at a later time without creating an oxide layer on the final GaAs based layer. In continuing processing, a decomposition process selectively decomposes the phosphor containing material cap layer, after which a regrowing process is performed to grow additional layers of the device structure. The capping, decomposition and regrowth processes can be repeated multiple times on the semiconductor devices on the wafer during device fabrication.
