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: Displays with integrated touch sensing circuitry are provided. An integrated touch screen can include multi-function circuit elements 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. The multi-function circuit elements can be, for example, capacitors in display pixels of an LCD that are configured to operate as display circuitry in the display system, and that may also be configured to operate as touch circuitry of the touch sensing system. For example, one or more circuit elements of the display pixel stackup 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.

Abstract: A touch screen includes a group of display pixels, each display pixel including display circuitry that includes a circuit element; and touch sensing circuitry in one or more of the display pixels including capacitive sensor circuitry that includes a common electrode acting as a charge collector and first and second conductive lines connectable to the charge collector by first and second switches, respectively, wherein at least a portion of one of the charge collector, the first conductive line, the second conductive line, the first switch, and the second switch includes the circuit element. Integrated touch screen displays are described that include 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.

Abstract: Integrated touch screens are provided including drive lines formed of grouped-together circuit elements of a thin film transistor layer and sense lines formed between a color filter layer and a material layer that modifies or generates light. The common electrodes (Vcom) in the TFT layer can be grouped together during a touch sensing operation to form drive lines. Sense lines can be formed on an underside of a color filter glass, and a liquid crystal region can be disposed between the color filter glass and the TFT layer. Placing the sense lines on the underside of the color filter glass, i.e., within the display pixel cell, can provide a benefit of allowing the color filter glass to be thinned after the pixel cells have been assembled, for example.

Abstract: En el documento se proveen pantallas táctiles integradas que incluyen líneas de transmisión formadas de elementos de circuito agrupados hechos de una capa de película delgada de transistor y líneas de detección formadas entre una capa filtro de color y una capa de material que modifica o genera luz. Los electrodos comunes (Vcom) en la capa TFT pueden estar agrupados durante una operación de detección de toque para formar líneas de transmisión. Las líneas de transmisión pueden estar formada en una parte inferior de un vidrio de filtro de color, y una región de cristal líquido puede estar dispuesta entre el vidrio de filtro de color y la capa TFT. Colocar las líneas de detección en la parte inferior del vidrio de filtro de color, es decir, dentro de la celda con pixel de visualización, puede ser beneficioso porque permite que el vidrio de filtro de color se adelgace una vez que las celdas pixel han sido ensambladas, por ejemplo.
