power consumption may decrease however for single finger detection this method and system of scanning may be the fastest that is theoretically possible and consume the least amount of power the first embodiment may also reduce noise or be less susceptible to noise than the prior art as stated above the scan rate may be substantially faster using the first embodiment as compared to prior art methods in other conventional scan methods individual electrodes need to be driven sequentially or in a spread balanced approach using conventional methods the numbers of measurements may match the electrode count thus for a 16 u00d7 16 array at least 16 drive measurements per axis may be required for finger detection and position determination in contrast in the first embodiment only two measurements capture an image of the entire x and y axes thus resulting in the large increase in speed it was also stated that noise may be reduced in the first embodiment specifically the signal on the touch sensor 30 is all received simultaneously the advantage of receiving the sense signals on all of the sense electrodes at the same time is that any noise on the touch sensor 30 will affect all of the measurements of the sense signals by a same degree typically the noise may be manifested as an offset in a signal on a sense line because the prior art may make measurements over a period of time the noise signal may change making the position determination less accurate however by making all of the measurements at the same time from all.
