    • A display (10) is provided with integral touch functionality. The display (10) includes a common electrode layer having row electrodes (76; VCOMR) arranged in rows and column electrodes (VCOMC) interposed between the row electrodes of each row. The row electrodes are electrically coupled by conductive paths (74). The row and column electrodes are coupled to touch sensor circuitry (68) that uses the row and column electrodes to detect touch events. Each electrode of the common electrode layer covers a respective portion of an array of pixels (52). Each pixel of the display has a respective aperture (124). The conductive paths that electrically couple row electrodes of the common electrode layer covers or otherwise blocks some light (126) from passing through pixels, resulting in reduced apertures. Dummy structures (104) are provided for other pixels that modify the apertures of the other pixels to match the reduced apertures associated with the conductive paths.
    • 显示器(10)具有整体触摸功能。 显示器(10)包括公共电极层,其具有排列成行和列电极(VCOMC)的行电极(76; VCOMR),插入在每行的行电极之间。 行电极通过导电路径(74)电耦合。 行和列电极耦合到触摸传感器电路(68),其使用行电极和列电极来检测触摸事件。 公共电极层的每个电极覆盖像素阵列的相应部分(52)。 显示器的每个像素具有相应的孔(124)。 电耦合公共电极层的行电极的导电路径覆盖或阻挡一些光(126)穿过像素,导致减小的孔径。 为其他像素提供虚拟结构(104),其修改其他像素的孔径以匹配与导电路径相关联的缩小的孔。

    • Common electrodes (Vcom) of integrated touch screens can be segmented into electrically isolated Vcom portions that can be operated as drive lines and/or sense lines of a touch sensing system. The touch screen can include high-resistivity connections between Vcom portions. The resistivity of the high-resistivity connections can be high enough so that touch sensing and image display can be performed by the touch screen, and the high-resistivity connections can provide an added functionality by allowing a charge build up on one of the Vcom portions to be spread to other Vcom portions and/or discharged from system by allowing charge to leak through the high-resistivity connections. In this way, for example, visual artifacts that result from charge build up on a Vcom portion can be reduced or eliminated.
    • 集成触摸屏的公共电极(Vcom)可以被分割成可以作为触摸感测系统的驱动线和/或感测线操作的电隔离Vcom部分。 触摸屏可以包括Vcom部分之间的高电阻连接。 高电阻率连接的电阻率可以足够高,以便触摸屏可以执行触摸感测和图像显示,并且高电阻率连接可以通过允许在Vcom部分之一上积累电荷来提供附加的功能 通过允许电荷通过高电阻率连接泄漏而扩散到其它Vcom部分和/或从系统排出。 以这种方式,例如,可以减少或消除由Vcom部分上的电荷产生的视觉伪像。

    • Reduction of the effects of differences in parasitic capacitances in touch screens is provided. A touch screen can include multiple display pixels with stackups that each include a first element and a second element. For example, the first element can be a common electrode, and the second element can be a data line. The display pixels can include a first display pixel including a third element connected to the first element, and the third element can contribute to a first parasitic capacitance between the first and second elements of the first display pixel, for example, by overlapping with the second element. The touch screen can also include a second display pixel lacking the third element. The second display pixel can include a second parasitic capacitance between the first and second elements of the second display pixel. The first and second parasitic capacitances can be substantially equal, for example.
    • 提供了降低触摸屏中寄生电容差异的影响。 触摸屏可以包括具有堆叠的多个显示像素,每个显示像素包括第一元素和第二元素。 例如,第一元件可以是公共电极,并且第二元件可以是数据线。 显示像素可以包括第一显示像素,该第一显示像素包括连接到第一元件的第三元件,并且第三元件可以有助于第一显示像素的第一元件和第二元件之间的第一寄生电容,例如通过与第二元件 元件。 触摸屏还可以包括缺少第三元素的第二显示像素。 第二显示像素可以包括第二显示像素的第一元件和第二元件之间的第二寄生电容。 例如,第一和第二寄生电容可以基本相等。

    • A display having data lines that can be configured between a display mode and a touch mode is disclosed. The display can have sense regions for sensing a touch or near touch on the display during the touch mode. These same regions can display graphics or data on the display during the display mode. During display mode, the data lines in the sense regions can be configured to couple to display circuitry in order to receive data signals from the circuitry for displaying. During touch mode, data lines in the sense regions can be configured to couple corresponding sense lines in the regions, which couples to touch circuitry, transmitting touch signals to the circuitry for sensing a touch or near touch. Alternatively, during touch mode, the data lines in the sense regions can be configured to couple to ground in order to transmit residual data signals to ground for discarding
