    Abstract: A multi-touch sensor panel is disclosed that can include a glass subassembly having a plurality of column traces of substantially transparent conductive material that can be formed on the back side, wherein the glass subassembly can also act as a cover that can be touched on the front side. Row traces of the same or different substantially transparent conductive material can then be located near the column traces, and a layer of dielectric material can be coupled between the column traces and the row traces. The row and column traces can be oriented to cross over each other at crossover locations separated by the dielectric material, and the crossover locations can form mutual capacitance sensors for detecting one or more touches on the front side of the glass subassembly.

    Abstract: 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.

    Abstract: Hier werden Flüssigkristallanzeige- (LCD) Berührungsbildschirme offenbart, bei denen die Berührungssensorelemente mit den Anzeigeschaltungen integriert sind. Die Integration kann eine Vielfalt von Formen annehmen. Die Berührungssensorelemente können vollständig innerhalb des LCD-Stapelaufbaus aber nicht zwischen der Farbfilterplatte und der Feldplatte implementiert sein. Alternativ können einige Berührungssensorelemente zwischen den Farbfilter- und Feldplatten angeordnet sein, wobei andere Berührungssensorelemente nicht zwischen den Platten liegen. In einer anderen Alternative können alle Berührungssensorelemente zwischen den Farbfilter- und Feldplatten liegen. Die letzte Alternative kann sowohl konventionelle als auch in einer Ebene schaltende (IPS) LCDs umfassen. In einigen Formen können Anzeigestrukturen auch eine Berührungsmessfunktion aufweisen. Techniken zur Herstellung und zum Betrieb solcher Anzeigen sowie verschiedene solche Anzeigen aufweisende Vorrichtungen sind ebenfalls offenbart.

    Abstract: The use of multiple stimulation signals having one or more frequencies and one or more phases to generate an image of touch on a touch sensor panel is disclosed. Each of a plurality of sense channels can be coupled to a column in a touch sensor panel and can have one or more mixers. Each mixer in the sense channel can utilize a circuit capable generating a demodulation frequency of a particular frequency. At each of multiple steps, various phases of one or more selected frequencies can be used to simultaneously stimulate the rows of the touch sensor panel, and the one or more mixers in each sense channel can be configured to demodulate the signal received from the column connected to each sense channel using the one or more selected frequencies. After all steps have been completed, the demodulated signals from the one or more mixers can be used in calculations to determine an image of touch for the touch sensor panel at each of the one or more frequencies.
