タッチパネル制御装置および電子機器
Abstract:
(EN)
The purpose of the present invention is to improve detection accuracy of touch coordinates in a second area within a first area while suppressing the total power consumption of a device. A control circuit (23) causes a drive circuit (21) and a detection circuit (22) to scan multiple drive electrodes and detection electrodes constituting a first area of a touch panel (1), and controls the drive circuit (21) and the detection circuit (22) so as to scan multiple drive electrodes and detection electrodes constituting a second area within the first area at least once after scanning of the first area has been performed until the next scanning of the first area is performed.
(FR)
Le but de la présente invention est d'améliorer la précision de détection de coordonnées tactiles dans une seconde zone à l'intérieur d'une première zone tout en supprimant la consommation d'énergie totale d'un dispositif. Un circuit de commande (23) amène un circuit d'attaque (21) et un circuit de détection (22) à balayer de multiples électrodes de commande et des électrodes de détection constituant une première zone d'un panneau tactile (1), et commande le circuit d'attaque (21) et le circuit de détection (22) de manière à balayer de multiples électrodes de commande et des électrodes de détection constituant une seconde zone à l'intérieur de la première zone au moins une fois après que le balayage de la première zone a été effectué jusqu'à ce que le prochain balayage de la première zone soit effectué.
(JA)
装置全体の消費電力を抑制しつつ、第1エリア内の第2エリアにおけるタッチ座標の検出精度を向上させる。制御回路(23)は、タッチパネル(1)の第1エリアを構成する複数の駆動電極および検出電極を、駆動回路(21)および検出回路(22)により走査を行うとともに、第1エリアの走査を行って次の第1エリアの走査を行うまでの間に、第1エリア内にある第2エリアを構成する複数の駆動電極および検出電極を、少なくとも1回以上走査を行うように駆動回路(21)および検出回路(22)を制御する。
