Touch Device Electrode Arrangement for Narrow Bezel

The patent applies dynamics by making the electrode states changeable over time. The control method dynamically switches electrodes between reading states and non-reading states based on timing phases. During each phase, only specific electrodes are in the reading state while others are in non-reading states, creating a time-varying detection pattern that resolves the contradiction between measurement precision and response speed.

The patent implements periodic action through multi-phase scanning cycles. The detection process is divided into multiple phases where different sets of electrodes are activated in sequence. This periodic switching allows the system to maintain consistent voltage environments during each phase while rapidly cycling through all electrodes, thereby achieving both accurate touch position determination and fast response times.

The patent applies segmentation by dividing the electrode array into multiple groups arranged on different edges of the touch panel. Instead of concentrating all electrodes on a single edge, the electrodes are segmented and distributed along multiple peripheral edges. This segmentation reduces the width required on any single edge while maintaining all necessary detection capabilities, thus resolving the contradiction between structural simplicity and aesthetic appearance.

The patent transitions from a one-dimensional single-edge electrode arrangement to a two-dimensional multi-edge distribution. By utilizing multiple edges of the touch panel for electrode placement, the design adds spatial dimensionality to the electrode arrangement. This dimensional change allows electrodes to be spread out along the perimeter, reducing the width of any individual edge while preserving the complete set of detection functions.
