System and method of determining stylus location on touch-sensitive display

摘要

An electronic device includes a touch-sensitive display including a plurality of touch sensors configured to detect touches on the touch-sensitive display. The touch sensors include a plurality of touch sensor jumpers that are spaced apart in the touch-sensitive display. The touch-sensor jumpers include attributes to facilitate identification of a location of a stylus relative to the jumpers. The stylus includes a device configured to obtain data relating to an attribute of at least one of the touch sensor jumpers of the touch-sensitive display, a processor operably coupled to the device to receive the data, and a transmitter operably coupled to the processor and configured to transmit to the electronic device, information based on the data. The electronic device includes a receiver that receives the information and a processor that is configured to determine the location of the stylus based on the information.

1. A stylus for use with a touch-sensitive display comprising a plurality of touch sensors including a plurality of drive electrodes and a plurality of sense electrodes disposed in a layer of the touch-sensitive display, the stylus comprising:
a device configured to obtain data relating to an attribute of at least one touch sensor jumper of a plurality of touch sensor jumpers of the touch-sensitive display of an electronic device, each touch sensor jumper being a conductive jumper disposed at a location of the touch-sensitive display at which a drive electrode of the plurality of drive electrodes and sense electrode of the plurality of sense electrodes cross each other such that the drive electrode is not electrically connected to the sense electrode; a processor operably configured to receive the data from the device; a transmitter operably coupled to the processor and configured to transmit, to the electronic device, information based on the data.
