Title (EN) TOUCH SCREEN LIQUID CRYSTAL DISPLAY
(FR) AFFICHAGE À CRISTAUX LIQUIDES À ÉCRAN TACTILE
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 stack up 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. Tn 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 - s witching (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) L'invention concerne des écrans tactiles à affichage à cristaux liquides (LCD) dans lesquels sont intégrés les éléments d'activation par pression au circuit d'affichage. L'intégration peut prendre diverses formes. Les éléments d'activation par pression peuvent être entièrement intégrés dans le système LCD mais à l'extérieur de la plaque du filtre couleur et de la plaque du réseau. En variante, certains éléments d'activation par pression peuvent se situer entre les plaques du filtre couleur et du réseau tandis que d'autres éléments d'activation par pression ne se situent pas entre les plaques. En variante, tous les éléments d'activation par pression peuvent se situer entre les plaques du filtre couleur et du réseau. Cette variante peut comprendre des affichages LCD classiques et à commutation dans le plan (IPS). Dans certains modes de réalisation, une ou plusieurs structures d'affichage peuvent également présenter une fonction d'activation par pression. L'invention concerne également des techniques de fabrication et d'exploitation desdits affichages, ainsi que divers dispositifs intégrant lesdits affichages.
