摘要： Power consumption of touch sensing operations for touch sensitive devices can be reduced by implementing a coarse scan (e.g., banked common mode scan) to coarsely detect the presence or absence of an object touching or proximate to a touch sensor panel and the results of the coarse scan can be used to dynamically adjust the operation of the touch sensitive device to perform or not perform a fine scan (e.g., targeted active mode scan). In some examples, the results of the coarse scan can be used to program a touch controller for the next touch sensing frame to idle when no touch event is detected or to perform a fine scan when one or more touch events are detected. In some examples, the results of the coarse scan can be used to abort a scheduled fine scan during the current touch sensing frame when no touch event is detected.

摘要： A touch controller that can configure touch circuitry according to a scan plan, which can define a sequence of scan events to be performed on a touch panel is disclosed. The touch controller can include a configurable transmit section to generate stimulation signals to drive the panel, a configurable receive section to receive and process touch signals from the panel, and a configurable memory to store the touch signals. The touch controller can also include a programmable scan engine to configure the transmit section, the receive section, and the memory according to the scan plan. The touch controller advantageously provides more robust and flexible touch circuitry to handle various types of touch events at the panel. An active stylus that can generate stimulation signals that can be detected by the touch controller during various touch events at the panel is also disclosed. 100-4 - 166 106 Slave Drive: 144 140| Controller| 114 -r142 152 MUX+ Drive --- | Controller ----------- --- 1Cnrle aSlave Sense Circuitry 108 Sense Circuitry -- 1507t 148 156$ Spectral Analyzer Touch Processor Wireless i 128 '------------+ *Communication -- Host Processor Chip a 10132 : 130 Program Storage Display Device

摘要： Attorney Docket No.: 10684-20475.41 Client Ref No.: P12617UTM/AU1 [00601 A touch panel configured to compensate for negative pixel effect is disclosed. The panel can be configured to increase a capacitive sense signal, indicative of a touching or hovering object, in order to compensate for an increase in negative capacitance when the object is poorly grounded. To perform the compensation, the panel can be configured to have split sense lines so as to increase the number of electric fringe fields forming the sense signal, thereby providing a sense signal that is substantially stronger than the negative capacitance signal. Each sense line can be split into two or more strips. -20 la-1198425 Inventors: Marduke YOUSEFPOR and Martin Paul GRUNTHANER Title: SPLIT LINES FOR NEGATIVE PIXEL COMPENSATION LINE S1"' FORM 1ST CAPACITIVE PATH 810 FORM 2ND CAPACITIVE PATH 820 FORM 1ST CAPACITANCE ALONG 1ST PATH & 2ND CAPACITANCE ALONG 2ND PATH, WHERE 1ST CAPACITANCE 830 GREATER THAN 2ND CAPACITANCE TO COMPENSATE FOR NEGATIVE PIXEL EFFECT

摘要： Touch sensitive device comprising: touch panel 824 sensing a proximate object; scan logic 810 performing a scan sequence on the panel to measure a touch by the object and grounding of the object; and processor 802, 828 to compensate touch measurements according to grounding measurements. The circuitry comprises: multiple first (drive) lines, at least one of the first lines driving the circuit with a stimulation signal and at least one other first line sensing a first capacitance between the object and ground; multiple second (sense) lines to form pixels 826 with first lines and sensing a second capacitance at the pixels indicative of a touch by the object; and a processor 802, 828 compensating the second capacitance with the first capacitance based on a grounding condition of the object. The drive lines sensing the first capacitance can be below or above the stimulated drive line. The touch device measures touch and grounding concurrently or by a first scan to measure touch and a second scan to measure grounding. Also claimed is a touch panel with switching circuitry coupled to drive lines. The device compensates for negative pixel effect in multi touch signal due to poor grounding of the touching object.
