Wireframe touch sensor design and spatial linearization touch sensor design

摘要

The touch sensor may include a thin conductor as at least a part of the sensor electrode. Some or all of the conductors may be metal wires. Sensor electrodes may not be noticeable to a human observer. In some such implementations, the sensor electrodes can be laid out and / or grouped in a pattern to create a spatial gradient. Some such embodiments involve spatial interweaving, spatial insertion, and / or length modulation of sensor electrodes. Such an embodiment can create a spatial gradient such that fewer rows and columns are required to provide a touch sensor panel with a given level of accuracy.
