    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 (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 translation: 这里公开了将触摸感测元件与显示电路集成的液晶显示(LCD)触摸屏。 整合可能采取各种形式。 触摸感应元件可以在LCD叠层内完全实现,但在彩色滤光板和阵列板之间可以完全实现。 或者,一些触摸感测元件可以在滤色器和阵列板之间,而其它触摸感测元件不在印版之间。 在另一替代方案中,所有触摸感测元件可以在滤色器和阵列板之间。 后一种替代方案可以包括常规和平面内切换(IPS)LCD。 在一些形式中,一个或多个显示结构也可以具有触摸感测功能。 还公开了用于制造和操作这种显示器的技术以及体现这种显示器的各种装置。

    Abstract: A switching circuit is disclosed. The switching circuit can comprise a plurality of pixel mux blocks, each of the pixel mux blocks configured to be coupled to a respective touch node electrode on a touch sensor panel, and each of the pixel mux blocks including logic circuitry. The switching circuit can also comprise a plurality of signal lines configured to be coupled to sense circuitry, at least one of the signal lines configured to transmit a touch signal from one of the respective touch node electrodes to the sense circuitry. The logic circuitry in each pixel mux block of the plurality of pixel mux blocks can be configured to control the respective pixel mux block so as to selectively couple the respective pixel mux block to any one of the plurality of signal lines.
