Abstract: Methods and devices employing in-cell and/or on-cell touch sensor components, including in-cell and/or on-cell black matrix material (80) that also may serve as a touch drive or sense electrode, are provided. In one example, an electronic display (18) may include a lower substrate (64), an upper substrate (70), and a black matrix material (80) that shields light between pixels of the electronic display (18). At least a portion of the black matrix material (80) may form all or part of a component of a touch sensor of the electronic display (18).

Abstract: Esta invención se refiere a presentadores visuales para los cuales el uso de elementos capacitivos de doble función no se traduce en ninguna reducción de la apertura del presentador visual. De esta manera, pueden fabricarse presentadores visuales sensibles al tacto que tengan relaciones de apertura que no sean peores que las de los presentadores no sensibles al tacto similares. Más específicamente, esta invención se refiere a poner elementos opacos sensibles al tacto para de esta manera asegurar que sean superpuestos sustancialmente por elementos opacos relacionados de presentación visual, asegurando así que la adición de los elementos sensibles al tacto no reduzca sustancialmente la relación de apertura. Los elementos de presentación visual de sensibilidad al tacto pueden ser, por ejemplo, líneas comunes que conecten varios elementos capacitivos que estén configurados para operar colectivamente como un elemento del sistema sensible al tacto.

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: 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: 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: A touch sensor panel having co-planar single-layer touch sensors fabricated on a single side of a substrate is disclosed. The drive and sense lines can be fabricated as column-like patterns in a first orientation and patches in a second orientation, where each column-like pattern in the first orientation is connected to a separate metal trace in the border area of the touch sensor panel, and all patches in each of multiple rows in the second orientation are connected together using a separate metal trace in the border area of the touch sensor panel. The metal traces in the border areas can be formed on the same side of the substrate as the patches and columns, but separated from the patches and column-like patterns by a dielectric layer.
