  • Patent number: 11137858
    Abstract: Location-based swing compensation for touch sensor panels can improve touch sensing performance. Due to differences in impedance characteristics of touch nodes at different locations in a touch sensor panel (due to differences in routing to touch nodes and due to differences in impedance with respect to ground (loading effects) of touch nodes), touch nodes can have non-uniform bandwidth characteristics which can manifest as non-uniform signal and signal-to-noise ratio (SNR) across the touch sensor panel. Additionally, the non-uniform signal can reduce the effectiveness of bootstrapping. Swing compensated stimulation signals can be applied to various touch nodes based on location and/or impedance characteristics of the various touch nodes. For example, the stimulation voltage can be increased for touch nodes with longer and/or thinner routing traces so that the signal at the touch node can be uniform with other touch nodes whose routing may be shorter and/or thicker.

After the power switch is made conspicuous, the user is able to see where to provide touch input on the electronic device to power on the electronic device.
