MUTUAL CAPACITIVE TOUCH SENSOR PATTERN

摘要

Elements are provided that mitigate the effects of at least one of charger noise, display noise, and non-grounding in a capacitive touch panel system. Such elements may include an array of sense lines made up of sense electrodes that are shaped differently from drive electrodes making up an array of drive lines, where the area occupied by the sense electrodes is substantially less than that taken up by the drive electrodes. Additionally, the shape of the sense electrodes, despite mitigating the aforementioned effects of charger noise, display noise, and non-grounding, maintains touch detection sensitivity.

主权项

1. An apparatus, comprising:
a plurality of drive lines extending along the apparatus in a first direction, each of the plurality of drive lines including a plurality of drive electrodes; and a plurality of sense lines extending along the apparatus in a second direction substantially perpendicular to the first direction, each of the plurality of sense lines including a plurality of sense electrodes, wherein the plurality of drive electrodes and the plurality of sense electrodes are asymmetrically shaped, and wherein each of the plurality of sense electrodes comprises a single elongated element and a plurality of protruding elements oriented in accordance with at least one angle relative to the elongated element.
