摘要： An embodiment of an improved touch surface controller for controlling a multi-point touch improved touch system controller(100) detects signal capacitance(Cs?g) from the pixels in the touch surface digitally, and therefore is easier and simpler to implement then previous approaches relying on analog detection and processing. Specifically, signal capacitance(Csig) is measured by measuring a number of clock cycles(N,N' ) taken to discharge(?T) or charge(?T') the input node(82) of a comparator(106). Embodiments of the disclosed touch surface controller are particularly useful in the context of detecting multiple simultaneous touches on the touch surface.

摘要： 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.
摘要翻译：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叠层内部完全实现，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，其它触摸感测元件不在板之间。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。后一种选择可以包括常规和平面切换（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。
