  • Patent number: 10929016
    Abstract: An information handling system touchscreen display detects touches at a touch detection surface as inputs to the information handling system based in part upon periodical calibrations performed by a touch controller. An embedded controller detects placement of a keyboard on the touchscreen display and in response commands the touch controller to cease the periodic calibrations for at least the portion of the touchscreen display on which the keyboard is placed. For instance, the embedded controller interfaces with a Hall sensor disposed under the touchscreen display that detects a magnet integrated in the keyboard. At removal of the keyboard, the embedded controller commands the touch controller to perform a calibration to update touch detection.

  • Patent number: 10860128
    Abstract: A touch display panel and device. A common electrode is provided between a display driving signal line and a touch line. The common electrode functions as a shielding pattern that prevents display noise of a touch sensing signal without increasing the number of masks used to form the touch display device. A touch load reducing layer is disposed in a region between the touch line and the common electrode, except for a region in which the common electrode and pixel electrodes overlap. This reduces the load of the touch line and improves touch sensing performance without having an adverse effect on display driving.

  • Patent number: 10854175
    Abstract: A computing device monitors support element strain to enable deployment of positionally-related components in conjunction with one another while the real-time positional relationship between these positionally-related components fluctuates during operation. An exemplary computing device includes a first component and a second component that are both mounted to a support element. The computing device may be subjected to mechanical loading during operation which may induce strain into the support element thereby affecting the nominal positioning between the positionally-related components. The computing device includes a displacement sensor to generate displacement data that is indicative of a real-time positional relationship between the components. This real-time positional relationship may be compensated while implementing desired functionality.
