Title (EN) TOUCH SCREEN LIQUID CRYSTAL DISPLAY
(FR) ÉCRAN D'AFFICHAGE TACTILE À CRISTAUX LIQUIDES
Abstract:
(EN) Disclosed herein are liquid-crystal display (LCD) touch screens that integrate the touch sensing elements with the display circuitry. The integration may take a variety of forms. Touch sensing elements can be completely implemented within the LCD stackup but outside the not between the color filter plate and the array plate. Alternatively, some touch sensing elements can be between the color filter and array plates with other touch sensing elements not between the plates. In another alternative, all touch sensing elements can be between the color filter and array plates. The latter alternative can include both conventional and in-plane- switching (IPS) LCDs. In some forms, one or more display structures can also have a touch sensing function. Techniques for manufacturing and operating such displays, as well as various devices embodying such displays are also disclosed.
(FR) La présente invention concerne des écrans d'affichage tactiles à cristaux liquides (LCD) qui intègrent les éléments tactiles à la circuiterie d'affichage. Cette intégration peut prendre diverses formes. Les éléments tactiles peuvent être complètement mis en oeuvre dans l'empilement du LCD, mais à l'extérieur, pas entre la plaque de filtre coloré et la plaque de matrice. En variante, certains éléments tactiles peuvent se trouver entre les plaques de filtre coloré et de matrice, d'autres éléments tactiles ne se trouvant pas entre les plaques. Dans une autre variante, tous les éléments tactiles peuvent se trouver entre les plaques de filtre coloré et de matrice. La dernière variante peut comprendre à la fois des systèmes LCD conventionnels et des systèmes LCD à commutation dans le plan (IPS). Dans certaines formes, une ou plusieurs structures d'affichage peuvent également présenter une fonction tactile. Cette invention concerne également des techniques pour fabriquer et faire fonctionner de tels écrans d'affichage, ainsi que divers dispositifs mettant en oeuvre de tels écrans d'affichage.
