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: An integrated liquid-crystal display (LCD) touch screen 100 is provided in which touch-sensing elements can be completely implemented within the LCD stack. The LCD stack comprises a first and a second polarizer; a first and a second substrate disposed between the polarizers, display control circuitry formed on the first substrate, a liquid crystal layer disposed between the substrates and at least one touch sensing element. At least one of the touch-sensing elements is disposed between the polarizers but not between the substrates. In some embodiments all of the touch sensing elements can be disposed outside the substrates. The touch sensing elements may be formed on the second substrate. The touch sensor may comprise a first layer with a plurality of drive electrodes 105a and a second layer with a plurality of sense electrodes 105b, preferably formed of indium-tin oxide (ITO) and separated by a dielectric layer. Alternative the touch-sensing elements may comprise active circuitry, such as thin film transistors (TFTs). The touch sensing element may employ a mutual capacitance or self capacitance touch-sensing arrangement. Alternative examples are also provided in which all touch sensing elements are disposed between the substrates. In some of these examples, one or more display control circuit elements can also have a touch sensing function. The substrates typically comprise a color filter plate and an array plate. Techniques for manufacturing and operating such displays, as well as various devices embodying such displays are also disclosed.

Abstract: Eine Magneterfassungstechnologie kann verwendet werden, um Änderungen oder Störungen (z. B. Änderungen der Magnetfeldstärke) in Magnetfeldern zu detektieren, und kann verwendet werden, um die genaue Position/Positionierung einer elektronischen Vorrichtung in der Nähe einer Magnetquelle zu messen. Um Störungen durch das statische Erdmagnetfeld zu vermeiden, kann ein moduliertes Magnetfeld zur magnetbasierten Näherungserfassung verwendet werden. Empfangene modulierte Magnetfeldsignale können demoduliert werden, um die Nähe des Sensors zur Quelle des modulierten Magnetfelds zu bestimmen. Vorrichtungen, wie Handschuhe oder Vorrichtungen mit Fingerspitzenknoten, die auf einem Empfangen modulierter Magnetfelder basieren, können verwendet werden, um eine Benutzerhandposition zu detektieren.
