Title (EN) MULTIPLE ELECTRODE TOUCH SENSITIVE DEVICE
(FR) DISPOSITIF TACTILE À ÉLECTRODES MULTIPLES
Abstract:
(EN) Two different sets of electrodes in a touch sensitive device are formed to produce an electric field gradient from one end of the electrodes to the other end when opposite ends of the electrodes are driven with different voltages. A signal measuring cycle is performed by alternately driving the ends of one set of electrodes, while using the other set of electrodes to receive signals. The roles of the sets of electrodes are then reversed, such that the set that was driven is now used to receive signals from the other set of electrodes. Reference signals may be obtained by driving both sides of one set of electrodes, and then both sides of the other set of electrodes. The signals obtained are then used to determine the touch position on the touch sensitive device.
(FR) L'invention concerne un dispositif tactile dans lequel sont formés deux ensembles différents d'électrodes pour produire un gradient de champ électrique d'une extrémité des électrodes à l'autre extrémité lorsque les extrémités opposées des électrodes sont excitées avec des tensions différentes. Un cycle de mesure de signaux est mis en œuvre en excitant alternativement les extrémités d'un ensemble d'électrodes, en utilisant l'autre ensemble d'électrodes pour recevoir les signaux. Les rôles des ensembles d'électrodes sont ensuite inversés, de telle sorte que l'ensemble qui a été excité soit à présent utilisé pour recevoir les signaux de l'autre ensemble d'électrodes. Des signaux de référence peuvent être obtenus en excitant les deux côtés d'un ensemble d'électrodes, puis les deux côtés de l'autre ensemble d'électrodes. Les signaux obtenus sont ensuite utilisés pour déterminer la position touchée sur le dispositif tactile.
