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: A system and method for autonomously scanning a sensor panel device, such as a multi-touch panel, is disclosed. In one embodiment, the system and method disables a sensor panel processor after a first predetermined amount of time has elapsed without the sensor panel device sensing any events. One or more system clocks can also be disabled to conserve power. While the processor and one or more system clocks are disabled, the sensor panel device can periodically autonomously scan the sensor panel for touch activity. Accordingly, if one or more results from the autonomous scans exceed a threshold, the sensor panel device re-enables the processor and one or more clocks to actively scan the sensor panel. If the threshold is not exceeded, then the sensor panel device continues to periodically autonomously scan the sensor panel without intervention from the processor. Furthermore, the sensor panel device can periodically perform calibration functions to account for any drift that may be present in the system.

Abstract: Styluses capable of generating stylus stimulation signals and touch sensitive devices capable of receiving stylus stimulation signals are disclosed. In one example, a stylus can receive a stimulation signal from a touch sensor of a touch sensitive device and generate a stylus stimulation signal by changing an amplitude or frequency of the received stimulation signal. The stylus can transmit the stylus stimulation signal back into the touch sensor of the touch sensitive device. The touch sensor can generate a touch signal based on the device's own stimulation signals and the stylus stimulation signal. The touch sensitive device can process the touch signal to determine a location of the stylus on the touch sensor. The stylus can include a force sensor to detect an amount of force applied to a tip of the stylus. The stylus stimulation signal can be modulated based on the force detected by the force sensor.

Abstract: Disclosed is a system and method for providing an oscillating signal of relatively precise frequency without using a signal provided by a crystal as a reference. Disclosed is a feedback oscillator circuit configured to output an oscillating signal having a frequency defined by a reference signal. The oscillating signal can be sent to one or more circuits including at least one frequency sensitive element. The frequency sensitive element produces an output signal which depends on the frequency of the oscillating signal. A controller controls the reference signal in order to cause an attribute of the output signal to have a value within a desired range.
