STYLUS UPLINK ENHANCEMENT FOR TOUCHSCREEN DEVICES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18000427 titled 'STYLUS UPLINK ENHANCEMENT FOR TOUCHSCREEN DEVICES

Simplified Explanation

The patent application describes an apparatus and method for compensating the effect of a user's hand or body contact with a touch screen while using an input device, such as a stylus, on a host device.

  • The compensation is achieved by applying an antiphase signal on a selective contact area, such as under the palm area, to increase the overall induced signal collected by the input device.
  • The input device receives a capacitively coupled uplink signal from the host device, which helps in determining the user's input on the touch screen.
  • By applying the antiphase signal, the patent aims to reduce or eliminate the interference caused by the user's hand or body contact, improving the accuracy of the input device.
  • The antiphase signal increases the induced signal collected by the input device from both the digitizer-to-pen and palm-to-pen paths, compensating for the loss of signal caused by the user's contact.
  • The innovation addresses the common issue of unintended touch inputs or interference caused by the user's hand or body contact while using a touch screen with an input device.
  • The method can be implemented in various touch screen devices, providing a more accurate and reliable user input experience.


Original Abstract Submitted

An apparatus and method for compensating the effect of a contact by a hand or other body part of a user with a touch screen of a host device while holding an input device on the strength of a capacitively coupled uplink signal provided to the input device (e.g. stylus) by the host device. The compensation is achieved by applying an antiphase signal on a selective contact area (e.g. under a palm area), to increase an overall induced signal collected by the input device from digitizer-to-pen and palm-to-pen paths.
