摘要： A touch sensor panels having segmented electrodes for both the drive and sense lines. The touch sensor panel may include a number of columns of sense electrodes and a number of rows of drive electrodes. Each of the drive and sense electrodes are connected to one of the metal bus lines using a connecting trace. Pixels on the touch sensor panel are formed by the unique pairings of individual drive electrodes and their adjacent sense electrodes. Electrically, the mutual capacitance of one touch-sensing pixel can be distinguished from the mutual capacitance of another touch sensing pixel because the two mutual capacitances are formed with combinations of different drive electrodes and sense electrodes. In one embodiment, the drive electrodes and sense electrodes in adjacent columns are staggered horizontally with respect to each other by half a Y-pitch of the electrodes.

摘要： Methods and apparatus for correcting electrical noise coupling from a liquid crystal module to a plurality of sense elements disposed within a touch sensor panel, and for reducing errors in touch detection algorithms. Erroneous signal values detected by the sense elements may be corrected by utilizing a set of reference elements for detecting noise common to both the sense elements and the reference elements, and a correction module for effectively subtracting out the noise from the sensed values. Errors in touch detection algorithms may be reduced by providing a more uniform spacing between successive sense elements. In some embodiments, one or more dummy ground elements may be inserted between adjacent sense elements in order to reduce signal interference.

摘要： Integrated touch sensor and solar panel stack-up configurations that may be used on portable devices, particularly handheld portable devices such as a media player or phone are disclosed. The solar cell stack-up configurations may include one or more touch sensor layers and one or more solar cell layers. By integrating both the touch sensors and the solar cell layers into the same stack-up, surface area on the portable device may be conserved. The solar panel may be mounted face down or otherwise obstructed by a touch sensor or other component. In this configuration, the device may include light channels that allow light into the device and direct the light around the component and to the solar panel. A parabolic reflector may be used to direct the light.

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： A touch sensor panel is disclosed including the use of ground guards or ground isolation bars to improve the touch event detection capabilities of the touch sensor panel. Ground isolation bars can be formed between connecting traces and adjacent sense lines to shunt near-field lines to ground and reduce unwanted capacitive coupling between the connecting traces and the sense lines. Ground guards can be formed between the drive and sense lines to partially or fully surround a sense line and shunt near-field lines to ground and improve the touch event detection capabilities of the sensor.

摘要： Normalization of regions of a sensor panel capable of detecting multi-touch events, or a sensor panel capable of detecting multi-hover events, is disclosed to enable each sensor in the sensor panel to trigger a virtual button in a similar manner, given the same amount of touch or hover. Each sensor produces an output value proportional to the level or amount of touch or hover. However, due to processing, manufacturing and physical design differences, the sensor output values can vary from region to region or panel to panel for a given amount of touch or hover. To normalize the sensor output values across regions, gain and offset information can be obtained in advance, stored in nonvolatile memory, and later used to normalize the sensor output values so that all regions in the sensor panel can trigger virtual buttons similarly, providing a uniform “response function” at any location on the sensor panel.
摘要翻译：公开了能够检测多触摸事件的传感器面板的区域的归一化，或者能够检测多悬停事件的传感器面板，以使得传感器面板中的每个传感器能够以类似的方式触发虚拟按钮，给定相同的方式触摸量或悬停量。每个传感器产生与触摸或悬停的水平或数量成比例的输出值。然而，由于处理，制造和物理设计差异，传感器输出值可以在给定量的触摸或悬停之间因地区或面板到面板而变化。为了在区域之间规范化传感器输出值，可以提前获得增益和偏移信息，存储在非易失性存储器中，然后用于归一化传感器输出值，以便传感器面板中的所有区域可以类似地触发虚拟按钮，从而提供均匀传感器面板上任何位置的“响应功能”。
