Abstract:
(EN) In order to detect, with a simple configuration, the capacitance distribution between a touch panel detection electrode and a stylus pen, this capacitance detection method involves: a readout step for turning ON a switch element selected from multiple drive sense switch elements (DST) between detection electrodes (E) and drive sense lines (DS) arranged side-by-side in the X axis direction, and reading out a linear sum signal from a detection electrodes (E), wherein said switch element is selected on the basis of a code sequence via control lines (DSS) arranged side-by-side in the Y axis direction; and a detection step for detecting capacitance.
(FR) Afin de détecter, avec une configuration simple, la répartition de capacitance entre une électrode de détection de panneau tactile et un crayon à stylet, le présent procédé de détection de capacitance faisant intervenir: une étape de lecture consistant à mettre en MARCHE un élément de commutateur choisi parmi des éléments de commutateur de détection d'excitation (DST) multiples entre des électrodes de détection (E) et des lignes de détection d'excitation (DS) disposées côte à côte dans la direction de l'axe X, et à lire un signal de somme linéaire à partir d'une électrode de détection (E), ledit élément de commutateur étant choisi sur la base d'une séquence de code via des lignes de commande (DSS) disposées côte à côte dans la direction de l'axe Y; et une étape de détection consistant à détecter la capacitance.
(JA) 簡素な構成によりタッチパネル上の検出電極とスタイラスペンとの間の容量分布を検出する。検出電極(E)とX軸方向に並ぶ駆動センスライン(DS)との間の複数の駆動センススイッチ素子(DST)から、Y軸方向に並ぶ制御ライン(DSS)を介して符号系列に基づき選択したスイッチ素子をオンして、検出電極(E)からの線形和信号を読み出す読み出し工程と、容量を検出する検出工程とを包含する。
