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 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.

摘要： An embodiment of an improved touch surface controller for controlling a multi-point touch surface such as a touch screen or a touch pad in a computer system is disclosed. The improved touch system controller detects signal capacitance 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 is measured by measuring a number of clock cycles taken to discharge or charge the input node of a comparator. Embodiments of the disclosed touch surface controller are particularly useful in the context of detecting multiple simultaneous touches on the touch surface.

摘要： A mouse having improved input methods and mechanisms is disclosed. The mouse is configured with touch sensing areas capable of generating input signals. The touch sensing areas may for example be used to differentiate between left and right clicks in a single button mouse. The mouse may further be configured with force sensing areas capable of generating input signals. The force sensing areas may for example be positioned on the sides of the mouse so that squeezing the mouse generates input signals. The mouse may further be configured with a jog ball capable of generating input signals. The mouse may additionally be configured with a speaker for providing audio feedback when the various input devices are activated by a user.

摘要： A multi-chip touch architecture for scalability can include one or more touch controller application specific integrated circuits (ASICs), and one or more switching circuits coupled between the one or more touch controller ASICs and the touch sensor panel. The number of touch controller ASICs and switching circuits can be scaled based on the size of the touch sensor panel. The touch controller ASICs can include an interface for data transfer between the touch controller ASICs to allow for parallel processing of an image of touch by more than one touch controller ASIC. The touch controller ASIC can also include a memory directly accessible by more than one processing circuit (e.g., hardware accelerators), and circuitry to dynamically adjust the coupling between portions (e.g., banks) of memory and inputs of the one or more processing circuits to minimize data transfer and improve processing speeds.

摘要： An electronic device may have a touch sensitive display that is insensitive to the presence of moisture. An array of pixels in the display may be used to display images. A display cover layer may overlap the array of pixels. A light source may illuminate an external object such as a finger of a user when the object contacts a surface of the display cover layer. This creates scattered light that may be detected by an array of light sensors. The light source may supply light to an edge of the display cover layer at an angle that ensures total internal reflection within the display cover layer is sustained across the display cover layer even when the display cover layer is immersed in water or otherwise exposed to moisture.

摘要： A display may have an array of light-emitting pixels that display an image in an active area of the display. These light-emitting pixels may be visible light pixels such as red, green, and blue thin-film organic light-emitting diode pixels. The display may also have a border region that runs along a peripheral edge of the active area. The border region may be free of pixels that display image light, whereas the active area may be free of light detectors. A non- optical touch sensor such as a capacitive touch sensor may overlap the active area to gather touch input from the active area. The non-optical touch sensor may not overlap any portion of the border region. In the border region, an optical sensor formed from infrared light- emitting pixels and infrared light-sensing pixels or other optical sensing circuitry may serve as an optical touch sensor.
