  • Patent number: 10719145
    Abstract: Touchscreen computing device having support for interference-free operation of one or two active pens. A dedicated screen ID and pen ID establish a one-to-one pairing between an active pen and a touchscreen of a single-screen or dual-screen device, thereby rejecting interference from additional pens or screens. For a dual-screen device, the screen-specific uplink signals are synchronized using master-slave, interlaced timing to avoid mutual interference and to support simultaneous operation of two active pens—one on each screen. The downlink signals from two active pens occur during the same timeslots, whereas the two uplinks—one from each of the two screens—are interleaved with two timeslots for pen downlinks. Screen-specific screen ID-twin parameter is created for each screen of a dual-screen device to alert a pen to send its downlink signals in the interleaved manner.
