Abstract: Abstract Combined force and proximity sensing is disclosed. One or more sensors can concurrently sense a force applied by an object on a device surface and a proximity of the object to the surface. In an example, a single sensor can sense both force and proximity via a resistance change and a capacitance change, respectively, at the sensor. In another example, multiple sensors can be used, where one sensor can sense force via either a resistance change or a capacitance change and another sensor can sense proximity via a capacitance change.

Abstract: Negative pixel compensation in a touch sensor panel is disclosed. The panel can compensate for a negative pixel effect in touch signal outputs due to poor grounding of an object touching the panel. To do so, the panel can reconstruct a captured touch image to remove negative pixel values indicative of the negative pixel effect and compute a composite image from the captured image and the reconstructed image to replace the captured image. In addition or alternatively, the panel can reconstruct a captured touch image to remove negative pixel values indicative of the negative pixel effect and replace the captured image with the reconstructed image.

Abstract: Using multiple digital mixers in touch panels to perform spectrum analysis of noise and identify low noise stimulation frequencies and use of the multiple stimulation frequencies and phases to generate an image of touch is disclosed. Each of a plurality of sense channels can be coupled to a column in a touch panel and can have multiple mixers. Each mixer in the sense channel utilizes a circuit generating a demodulation frequency of a particular frequency. At each of multiple steps, various phases (e.g. positive and negative) of selected frequencies can be used to simultaneously stimulate the rows of the touch sensor panel, and the multiple mixers in each sense channel can be configured to demodulate the signal received from the column connected to each sense channel using the selected frequencies in phase. The selected stimulation frequencies may be low noise frequencies. The demodulated signals from the multiple mixers can be used in calculations to determine an image of touch at each frequency. Also claimed is touch screen where image of touch is obtained during vertical blanking. Driver logic is claimed including a charge pump for converting low level supply voltage into higher level voltage and utilising the higher level voltage to generate reduced amplitude stimulation signals for driving a plurality of drive lines; a plurality of sense channels each including a charge amplifier for receiving a sense signal from a different sense line, wherein each charge amplifier in each sense channel includes a reduced feedback capacitance whose physical size is scaled down in accordance with a lower amount of charge injected into the sense lines by the reduced amplitude stimulation signals.

Abstract: Utilisation de multiples fréquences et phases de stimulation pour générer une image d'un toucher sur un panneau de capteurs de toucher (124, 200, 524). Chacun parmi une pluralité de canaux de détection (108, 300) peut être couplé à une colonne dans un panneau de capteurs de toucher (124, 200, 524) et peut comporter de multiples mélangeurs (304). Chaque mélangeur (304) dans le canal de détection (108, 300) peut utiliser un circuit capable de générer une fréquence de démodulation d'une fréquence particulière. Au niveau de chacune des multiples étapes, diverses phases de fréquences sélectionnées peuvent être utilisées pour stimuler simultanément les rangées du panneau de capteurs de toucher (124, 200, 524), et les multiples mélangeurs (304) dans chaque canal de détection (108, 300) peuvent être configurés de façon à démoduler le signal reçu de la colonne raccordée à chaque canal de détection (108, 300) au moyen des fréquences sélectionnées. Une fois que l'ensemble des étapes a été achevé, les signaux démodulés à partir des multiples mélangeurs (304) peuvent être utilisés dans des calculs pour déterminer une image d'un toucher pour le panneau de capteurs de toucher (124, 200, 524) à chaque fréquence.
