Title (EN) TOUCH SCREEN AND DRIVING METHOD THEREFOR, AND DISPLAY DEVICE
(FR) ÉCRAN TACTILE, SON PROCÉDÉ DE PILOTAGE, ET DISPOSITIF D’AFFICHAGE
(ZH) 触摸屏及其驱动方法和显示装置
Abstract:
(EN) A touch screen and a driving method therefor, and a display device. The touch screen comprises a liquid crystal cell (3) formed by aligning an array substrate (1) and a colour film substrate (2) and a fixed electrode (4) arranged on one side of the array substrate (1) away from the colour film substrate (2), and further comprises a shielding electrode (5) and a common electrode (6), wherein the common electrode (6) is arranged on the array substrate (1); the shielding electrode (5) is located on one side of the common electrode (6) away from the fixed electrode (4); the common electrode (6) is used as a first driving electrode when pressure touch control is performed; and the position of the fixed electrode (4) corresponds to that of the common electrode (6) for assisting the first driving electrode to detect a touch control pressure when the pressure touch control is performed. The touch screen achieves pressure sensing touch control subject to a self-capacitance principle, which not only reduces the manufacturing difficulty of a pressure sensing touch screen and improves the touch control accuracy of the pressure sensing touch screen, but also reduces production and assembly costs of the pressure sensing touch screen, so as to enable the pressure sensing touch screen to be promoted more quickly and widely.
(FR) L'invention concerne un écran tactile, son procédé de pilotage, et un dispositif d’affichage. L'écran tactile comprend une cellule à cristaux liquides (3) formée par alignement d'un substrat de réseau (1) et d'un substrat de film coloré (2) ainsi qu'une électrode fixe (4) disposée d'un côté du substrat de réseau (1) à l'écart du substrat de film coloré (2), et comprend en outre une électrode de protection (5) et une électrode de référence (6). L'électrode de référence (6) est placée sur le substrat de réseau (1), l'électrode de protection (5) est située d'un côté de l'électrode de référence (6) à l'écart de l'électrode fixe (4), l'électrode de référence (6) sert de première électrode de pilotage lorsqu'une commande tactile par pression est réalisée, et la position de l'électrode fixe (4) correspond à celle de l'électrode de référence (6) pour aider la première électrode de pilotage à détecter une pression de commande tactile lorsque la commande tactile par pression est réalisée. L'écran tactile permet d'obtenir une commande tactile sensible à la pression et soumise au principe de capacité propre, qui non seulement réduit la difficulté de fabrication d'un écran tactile sensible à la pression et améliore la précision de commande tactile dudit écran, mais réduit aussi les coûts de production et de montage dudit écran, de manière à permettre une promotion plus rapide et plus large de cet écran tactile sensible à la pression.
(ZH) 一种触摸屏及其驱动方法和一种显示装置。该触摸屏包括由阵列基板(1)和彩膜基板(2)对盒而成的液晶盒(3)以及设置在阵列基板(1)的远离彩膜基板(2)的一侧的固定电极(4),还包括屏蔽电极(5)和公共电极(6),公共电极(6)设置在阵列基板(1)上,屏蔽电极(5)位于公共电极(6)的远离固定电极(4)的一侧,公共电极(6)用作压力触控时的第一驱动电极,固定电极(4)与公共电极(6)的位置相对应,用于在压力触控时辅助第一驱动电极对触控压力进行探测。该触摸屏实现了自电容原理的压力感应触控,不仅降低了压力感应触摸屏的制作难度,提高了压力感应触摸屏的触控精确度,而且降低了压力感应触摸屏的生产和组装成本,从而使压力感应触摸屏能更加快速并广泛地推广。
