Self-Capacitance And Mutual Capacitance Touch Sensor Panel Architecture
- Cupertino CA, US Jean-Marie BUSSAT - San Jose CA, US Robert Leo SHERIDAN - Sunnyvale CA, US Sagar Rajiv VAZE - San Jose CA, US
International Classification:
G06F 3/044 G06F 3/041 G06F 3/047
Abstract:
A touch sensor panel includes a first set of touch electrodes configured to operate as drive lines and that are disposed in a first layer of the touch sensor panel. The touch sensor panel also includes a second set of touch electrodes configured to operate as sense lines and that are disposed in a second layer of the touch sensor panel, different than the first layer of the touch sensor panel, such that one or more mutual capacitance touch nodes are formed by the first set of touch electrodes and the second set of touch electrodes. The touch sensor panel also includes a third set of touch electrodes configured to operate as self-capacitance electrodes and that are disposed in the first layer or the second layer of the touch sensor panel.

International Classification:
G06F 3/044 G06F 3/041
Abstract:
Touch sensor panels (or touch screens) can improve signal-to-noise ratio (SNR) using touch electrode patterns for differential drive and/or differential sense techniques. In some examples, a touch sensor panel can include a two-dimensional array of touch nodes formed from a plurality of touch electrodes. Each column (or row) of touch nodes can be driven with a plurality of drive signals. For example, a first column (or row) of touch nodes can be driven by a first drive signal applied to one or more first touch nodes in the first column (or row) and a second drive signal applied to a one or more second touch nodes of the first column (or row). In some examples, the first drive signal and the second drive signal can be complimentary drive signals. In some examples, each row (or column) of touch electrodes can be sensed by differential sense circuitry.

International Classification:
G06F 3/044
Abstract:
High aspect ratio touch sensor panels are disclosed in which multiple row electrode blocks can be formed in a single row within an active area of the touch sensor panel, each row electrode block including a plurality of vertically adjacent row electrodes, or in some instances only one row electrode. In addition, each column electrode can be separated into multiple column electrode segments, each column electrode segment being vertically oriented and formed in a different column. The column electrode segments associated with any one column electrode can be spread out so that each of these column electrodes segments can be co-located and associated with a different row electrode block.
