Title (EN) PROJECTED-CAPACITIVE (PCAP) TOUCHSCREEN
(FR) ÉCRAN TACTILE CAPACITIF PROJETÉ (PCAP)
Abstract:
(EN) Various configurations and arrangements for touchscreens are disclosed to accommodate for one or more optical discontinuities that can be present within these touchscreens. When the one or more optical discontinuities are present, these configurations and arrangements of the touchscreens present a single layer of transparent conductive material that can be difficult to perceive by a human eye when viewing the touchscreens. Additionally, various edge correction techniques are disclosed to adjust mutual capacitances along a perimeter of the touchscreens. These edge correction techniques adjust mutual capacitances such that the values of the mutual capacitances are substantially uniform throughout.
(FR) Divers configurations et agencements pour des écrans tactiles sont décrits pour s'adapter à une ou plusieurs discontinuités optiques qui peuvent être présentes dans lesdites écrans tactiles. Lorsque la ou les discontinuités optiques sont présentes, lesdits configurations et agencements des écrans tactiles présentent une seule couche de matériau conducteur transparent qui peut être difficile à percevoir à l’œil humain lors de la visualisation des écrans tactiles. De plus, diverses techniques de correction de contours sont décrites pour ajuster les capacitances mutuelles le long d'un périmètre des écrans tactiles. Lesdites techniques de correction de contours ajustent les capacitances mutuelles de sorte que les valeurs des capacitances mutuelles soient sensiblement uniformes dans l'ensemble.
