Abstract: 터치센서패널을터치하거나이에근접한물체의존재또는부재를대략적으로검출하는대략적스캔(예를들어, 뱅크화된공통모드스캔)을구현함으로써터치감지장치에대한터치감지동작의전력소비가감소될수 있고, 대략적스캔의결과는정밀스캔(예를들어, 목표된활성모드스캔)을수행하거나수행하지않도록터치감지장치의동작을동적으로조절하는데이용될수 있다. 일부예에서, 대략적스캔의결과는아무런터치이벤트도검출되지않을때 다음터치감지프레임에대한터치제어기를유휴상태가되도록또는하나이상의터치이벤트가검출될때 정밀스캔을수행하도록프로그램하는데이용될수 있다. 일부예에서, 대략적스캔의결과는아무런터치이벤트도검출되지않을때 현재의터치감지프레임동안스케쥴링된정밀스캔을중단시키는데이용될수 있다.

Abstract: 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.

Abstract: A touch controller for flexible scanning operation is disclosed. The touch controller can include circuitry configured to perform coarse detection scans, select a fine scan type based on results from the coarse detection scans, and perform a fine scan corresponding to the selected fine scan type. A fine mutual capacitance scan can be performed when conditions corresponding to a poorly grounded or ungrounded object or user are detected based on the coarse detection scans. A fine fully-bootstrapped self-capacitance scan can be performed when conditions corresponding to a well-grounded object or user are detected based on the coarse detection scans. A touch processor can be configured to sense touch events from the fine scan.
