Abstract: A touch screen including display pixels with capacitive elements is provided. The touch screen includes first common voltage lines connecting capacitive elements in adjacent display pixels, and a second common voltage line connecting first common voltage lines. The pixels can be formed as electrically separated regions by including breaks in the common voltage lines. The regions can include a drive region that is stimulated by stimulation signals, a sense region that receives sense signals corresponding to the stimulation signals. A grounded region can also be included, for example, between a sense region and a drive region. A shield layer can be formed of a substantially high resistance material and disposed to shield a sense region. A black mask line and conductive line under the black mask line can be included, for example, to provide low-resistance paths between a region of pixels and touch circuitry outside the touch screen borders.

Abstract: Es wird ein Berührungssensorfeld offenbart, das einen oder mehrere leitfähige Bereiche umfasst, die in einem äußeren Bereich eines Berührungssensorfelds angeordnet sind. Der Berührungssensorfeldaufbau kann ein Substrat, eine oder mehrere tiefer liegende Schichten, eine oder mehrere strukturierte transparente leitfähige Schichten und einen oder mehrere leitfähige Bereiche umfassen. In manchen Beispielen kann der Aufbau eine oder mehrere Passivierungsschichten umfassen. Die eine oder die mehreren tiefer liegenden Schichten, strukturierten transparenten leitfähigen Schichten, der eine oder die mehreren leitfähigen Bereiche und die Passivierungsschichten können auf der gleichen Seite des Substrats, auf verschiedenen Seiten des Substrats oder auf verschiedenen Substraten aufgebracht sein. Der eine oder die mehreren leitfähigen Bereiche können unerwünschtes Licht am Eindringen in eine oder mehrere Schichten des Berührungssensoraufbaus hindern und Veränderungen der Eigenschaften der einen oder mehreren Schichten des Aufbaus verhindern.

Abstract: Verfahren zum Herstellen von Berührungssensoren mit einer oder mehreren Schutzbahnen zum Reduzieren des Effekts von Feuchtigkeitsschäden werden bereitgestellt. Ein beispielhaftes Verfahren kann das Ausbilden einer oder mehrerer Schutzbahnen zwischen einer Kante des Berührungssensors und den Metallbahnen umfassen, die die Ansteuersleitungen und die Abtastleitungen zu den Kontaktstellen leiten. Die eine oder die mehreren Schutzbahnen können von den Ansteuerleitungen und den Abtastleitungen entkoppelt sein, um die inneren Metallbahnen vor Feuchtigkeitsschäden zu schützen. In einigen Beispielen können Enden der einen oder der mehreren Schutzbahnen durch Kupfer mit Masse gekoppelt sein. In anderen Beispielen können Enden der einen oder der mehreren Schutzbahnen durch Indiumzinnoxid mit Masse gekoppelt sein, oder die eine oder die mehreren Schutzbahnen können durch einen Streifen von Indiumzinnoxid mit Masse gekoppelt sein. In noch anderen Beispielen kann die Schutzbahn massefrei sein (z. B. nicht an Masse gekoppelt).

Abstract: Aspects of the present disclosure relate to single-domain electrode configurations that may be implemented in the unit pixels of a LCD device, such as a fringe field switching (FFS) LCD, to provide a "pseudo-multi-domain" effect, wherein the benefits of both conventional single-domain and multi-domain pixel configuration devices are retained. In accordance with aspects of the present technique, single-domain unit pixels are angled or tilted in differing directions with respect to a vertical axis of the LCD panel (e.g., y-axis) to provide an alternating and/or periodic arrangement of different-angled pixel electrodes along each scanning line, data line, or a combination of both scanning and data lines. In this manner, the transmittance rates of conventional single-domain LCD panels may be retained while providing for improved viewing angle and color shift properties typical of conventional multi-domain LCD panels.

Abstract: An integrated touch screen display includes multi-function circuit element/s that form part of the display circuitry of the display system that generates an image on the display, and also form part of the touch sensing circuitry of a touch sensing system that senses one or more touches on or near the display. For example, one or more circuit elements of the display pixel stack can form a conductive portion of the touch sensing system, such as a charge collector, which can be operated with switches and conductive lines to sense touch. In an embodiment a common electrode xVcom415 in a fringe field switching LCD can serve as a multifunction circuit element. Using transistors S1, S2 and S3 the common electrodes can operate as a charge collected in a charge transfer capacitive touch sensing system. A xVcom Bridge 423 can connect xVcom of one pixel to be xVcom of an adjacent pixel. During a display phase transistor S1 417 performs switching of data lines 413 to connect data lines to pixel electrodes 416 and transistor S2 419 can switch xVcom lines. During touch operation S1 can be switched off and transistor S2 and transistor S3 can be switched to xVcom and data lines respectively and alternatively so as to operate the charge transfer capacitive sensor.

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.
