Abstract:
1. A borderless touchscreen panel, comprising: a plurality of transmit electrodes each extending in a first direction, the plurality of transmit electrodes including a first transmit electrode and a last transmit electrode; a plurality of sensing electrodes extending in a second direction perpendicular to the first direction, wherein a first subset of the plurality of sensing electrodes are coupled to receiving traces routed beneath the first transmit electrode and extending in the first direction along a length of the first transmit electrode, and a second subset of the plurality of sensing electrodes are coupled to receiving traces routed beneath the last transmit electrode and extending in the first direction along a length of the last transmit electrode; and control circuitry operable during a first mode to apply first drive signals to the plurality of transmit electrodes except the first transmit electrode and to receive first sense signals from the first subset via the receiving traces routed beneath the first transmit electrode.
