  • Publication number: 20220221938
    Abstract: Systems, apparatus, and methods for providing haptic feedback at electronic user devices are disclosed. An example apparatus includes processor circuitry to perform operations to instantiate touch response area detection circuitry to identify a touch response area of a display screen; haptic feedback analysis circuitry to detect that a location of a touch on the display screen is within the touch response area and output an instruction to cause a haptic feedback response; and haptic feedback control circuitry to, in response to the instruction, cause a haptic feedback actuator to generate the haptic feedback response based on the location of the touch and a property of the haptic feedback response.

  • Publication number: 20220121318
    Abstract: In one example, an electronic device may include a touch screen display and a touch sensor associated with the touch screen display. The touch sensor is to detect a capacitive coupling between an input pen and the touch screen display. Further, the electronic device may include a controller, coupled to the touch sensor, to detect a hover operational mode of the input pen when the capacitive coupling is in a first threshold range and detect a touch operational mode of the input pen when the capacitive coupling is in a second threshold range. The second threshold range may be greater than the first threshold range.

  • Patent number: 11079638
    Abstract: In one example, a display device may include a display panel having a light guide plate, a printed circuit board (PCB) to generate a driving signal to drive the display panel, a driving integrated circuit (IC) mounted on the display panel to process the driving signal, a timing controller (TCON) integrated into the driving IC to control driving of the display panel, and a flexible printed circuit to electrically connect the driving IC and the PCB. The PCB may be disposed behind the driving IC.

  • Publication number: 20190227691
    Abstract: Controlling a touch-sensitive display unit is described. In an example implementation, a physical configuration of a mobile computing device is identified. The physical configuration may be one of a clamshell mode and a tablet mode. Further, based on the physical configuration of the mobile computing device, the operational state of the touch-sensitive display unit of the mobile computing device is switched to one of an active state and an inactive state.

  • Publication number: 20190022990
    Abstract: The present subject matter relates to self-healing touch-surface components. In an example implementation, a self-healing touch-surface component of an electronic device comprises a self-healing layer disposed over a touch-surface component. The self-healing layer includes polyurethane, polyester, epoxy, polyurethane microcapsules filled with di-n-butyltin dilaurate, and a polysiloxane mixture.

  • Publication number: 20190004625
    Abstract: A device is disclosed. The touch device comprises a first detection unit, a second detection unit and a control unit. The first detection unit is to generate first information indicating a position of a touch in response to the touch. The second detection unit disposed beneath the first detection unit is to generate second information indicating a measurement of the touch in response to the touch. The control unit coupled to the first and second detection units is to associate the first information and the second information. The generation of the first information is insulated from the generation of the second information.

  • Patent number: 9632600
    Abstract: Example embodiments relate to stylus. For example, a stylus includes a pressure sensor and a sensor holder in contact with the pressure sensor. The stylus also includes a first spring having a distal end and a proximal end. The distal end is in contact with the sensor holder. The stylus further includes a spring holder in contact with the proximal end. The stylus further includes a second spring in contact with the sensor holder to apply a preloading force to the pressure sensor. The entirety of the spring holder and a portion of the first spring are positioned within the second spring. The stylus further includes a tip portion in contact with the spring holder to compress the first spring in response to a compressing force applied to the tip portion.
