Title
(EN) TOUCH SENSOR SYSTEM, AND ELECTRONIC DEVICE
(FR) SYSTÈME DE CAPTEUR TACTILE ET DISPOSITIF ÉLECTRONIQUE
Abstract
(EN)
A touch sensor system (101) disclosed herein includes a driver (105) which (a) drives, on the basis of code sequences (di (= di1, di2,..., diN, where i = 1,..., M)) which are orthogonal to one another and include +1 or -1 and each of which has a length N, drive lines (DL1 through DLM) in parallel for each of (I) a first capacitance column (Ci1) between the drive lines and a first sense line (SL1) and (II) a second capacitance column (Ci2) between the drive lines and a second sense line (SL2) so that voltages +V or -V are applied and (b) outputs outputs (sFirst = (s11, s12,..., s1N)) from the first capacitance column (Ci1) and outputs (sSecond = (s21, s22,..., s2N)) from the second capacitance column (Ci2), a decoding section (108) which estimates (a) on the basis of a first inner product operation of the outputs (sFirst) and the code sequences (di), a first capacitance value in the first capacitance column (Ci1) and (b) on the basis of a second inner product operation of the outputs (sSecond) and the code sequences (di), a second capacitance value in the second capacitance column (Ci2), a touch panel (102) having a two-dimensional region (112) made up of a hand placing region (113) and a remainder region (114) being a region other than the hand placing region (113); a hand placing region processing section (103) for carrying out a first process in accordance with a hand placing region touch signal corresponding to a touch to the hand placing region (113); and a plot input processing section (104) for carrying out a second process different from the first process, in accordance with a remainder region touch signal corresponding to a touch to the remainder region (114), and the hand placing region (113) is a hand placing region that includes a region where a hand is placed for input to the touch panel (102), and the remainder region touch signal includes a plot signal generated by a stylus and/or a touch signal generated by a finger.

L'invention concerne un système de capteur tactile (101) comprenant un circuit d'attaque (105) qui (a) attaque, sur la base de séquences de code (di (= di1, di2,..., diN, où i = 1,..., M)) orthogonales les unes aux autres et incluant +1 ou -1 et dont chacune est de longueur N, des lignes d'attaque (DL1 à DLM) en parallèle pour chacune (I) d'une première colonne de capacité (Ci1) entre les lignes d'attaque et une première ligne de lecture (SL1) et (II) une seconde colonne de capacité (Ci2) entre les lignes d'attaque et une seconde ligne de lecture (SL2), de manière à ce que des tensions +V ou -V soient appliquées, et (b) délivre des sorties (sFirst = (s11, s12,..., s1N)) à partir de la première colonne de capacité (Ci1) et des sorties (sSecond = (s21, s22,..., s2N)) à partir de la seconde colonne de capacité (Ci2), une section de décodage (108) qui estime (a) sur la base d'une première opération de produit intérieur entre les sorties (sFirst) et les séquences de code (di), une première valeur de capacité sur la première colonne de capacité (Ci1) et (b) sur la base d'une seconde opération de produit intérieur entre les sorties (sSecond) et les séquences de code (di), une seconde valeur de capacité sur la seconde colonne de capacité (Ci2), un panneau tactile (102) comportant une région bidimensionnelle (112) constituée d'une région de positionnement de la main (113) et d'une région restante (114) qui est une région autre que la région de positionnement de la main (113); une section de traitement de région de positionnement de la main (103) destinée à mettre en œuvre un premier traitement en fonction d'un signal de toucher de la région de positionnement de la main correspondant au fait de toucher la région de positionnement de la main (113) ; et une section de traitement d'entrée de tracé (104) destinée à effectuer un second traitement différent du premier traitement en fonction d'un signal de toucher de la région restante correspondant au fait de toucher la région restante (114), la région de positionnement de la main (113) étant une région de positionnement de la main qui contient une région sur laquelle la main est positionnée pour effectuer une entrée sur le panneau tactile (102), et le signal de toucher de la région restante comprenant un signal de tracé généré par un stylet et/ou un signal de toucher généré par un doigt.
