A method includes utilizing a plurality of electrodes of a capacitive touch-sensitive display to detect touches on the touch-sensitive display, concurrently driving a first group of the plurality of electrodes, and detecting an object spaced from the touch-sensitive display utilizing a second group of the plurality of electrodes while concurrently driving the first group of the plurality of electrodes.
摘要:
A touch-sensitive input device includes a first set of conductors and a second set of conductors. The first set of conductors include a first conductor including a plurality of first fingers extending from a first spine, and a second conductor including a plurality of second fingers extending from a second spine, wherein the first fingers are interleaved with the second fingers. The second set of conductors are separated from the first set of conductors by a dielectric material and include a third conductor including a plurality of third fingers extending from a third spine, and a fourth conductor including a plurality of fourth fingers extending from a fourth spine, wherein the third fingers are interleaved with the fourth fingers.
摘要:
The invention is a system for reducing finger-coupling capacitance of a touch-sensor panel such that finger-coupled noise signals do not overwhelm the sensing circuit and render the panel unable to detect the finger position.
摘要:
A touch-sensitive input device includes a cover, a set of first conductors disposed between the cover and a substrate, the first conductors including at least two fingers connected at an end of the fingers, dummy conductors disposed between the first conductors and between the fingers of the first conductors, and a second set of conductors disposed on an opposite side of the substrate.
摘要:
An apparatus, and an associated method, tests for an anomaly, such as an open circuit or a short circuit, at a touch sensing device. An electrical characteristic sensor senses an electrical characteristic at an electrode of the touch sensing device. Responsive to the sensed electrical characteristic, a determination is made by a determiner as to whether a short or open circuit or other anomaly exists at the touch sensing device.
摘要:
A method includes displaying information in a display area of a touch-sensitive display, receiving touch data from the display area and touch data from a non-display area where information is not displayed, and determining a touch location in the display area based on the touch data from the display area and the touch data from the non-display area.
