  • Patent number: 11662861
    Abstract: An information handling system presents visual images at a display that includes a display panel having a capacitive touch detection surface supported by an indium tin oxide layer disposed between a front layer, such as polarizer, and a display cell. To prevent excessive charge build up associated with the capacitive touch detection surface, a conductive ink is applied at the display panel perimeter and interfaced with a ground at the rear side of the display panel. In one example embodiment, a non-conductive ink insulates the conductive ink from the display panel except as desired to transfer excess charge from the indium tin oxide layer. The conductive ink may interface directly with the indium tin oxide layer or indirectly through a second non-conductive ink having greater conductivity than the insulative non-conductive ink.

  • Patent number: 11663367
    Abstract: An information handling display presents visual images in a privacy mode that manages visual image brightness with a local processing resource when a predetermined condition is detected, such as multiple individuals in the display field of view. For example, an information handling system provides visual information to a display timing controller that includes a pulse width modulation signal to command display backlight brightness. When in a privacy mode, the timing controller or another processing resource modifies the pulse width modulation signal to command a predetermined reduced brightness, such as in a range of 30 to 50 nits of reduced brightness.

  • Patent number: 11639145
    Abstract: A vehicle structure material strengthening system and a vehicle containing the same are described. The vehicle structure material strengthening system has at least one collision sensor, a processor, and a power supply. The collision sensor is suitable for being mounted on the vehicle. The processor is electrically connected to the collision sensor for receiving a collision signal from the collision sensor, and determines whether to transmit a power activation signal according to the collision signal. The power supply is electrically connected to the processor and the vehicle. When the collision signal is greater than or equal to a collision threshold, the processor transmits the power activation signal to the power supply, wherein the power supply transmits a circuit to the vehicle according to the power activation signal; or when the collision signal is less than the collision threshold, the processor does not transmit the power activation signal.
