摘要： A multi-touch sensor panel can be created using a substrate with column and row traces formed on either side. Metal traces running along the border of the substrate can be used to bring the row traces to the same edge as the column traces. A single flex circuit can be fabricated to connect to the rows and columns on directly opposing sides. Flex printed circuits can be bonded to directly opposing attachment areas of a substrate by cooling one side of the substrate while bonding the other. In addition, “coverlay” material extending over right-angled traces on the flex circuit ensure that those traces do not get shorted should conductive bonding material get squeezed out during bonding. Furthermore, a spacer is placed at the distal end of the flex circuit to apply even bonding pressure over the entire flex circuit attachment area during bonding.

摘要： Systems and methods for touch screens with integrated transparent conductive material resistors are provided. Metal traces on the surface of a touch screen may be subject to radio-frequency interference (RFI) that can adversely affect the performance of the touch screen. Transparent conductive material resistors inserted within the metal trace paths can be used to form low-pass filters which can reduce the affect of the RFI.

摘要： Determination of phases of multiple stimulation signals to be simultaneously applied to a touch sensor panel is disclosed. A matrix may be determined that is invertible and has a gain greater than one, where each row of the matrix may represent a single step among multiple steps needed to compute values for generating an image of touch, each column of the matrix may represent a drive line of the touch sensor panel to be stimulated, and each element of the matrix may represent the phase of the stimulation signal to be applied to a particular drive line in a particular step. For each step, stimulation signals having phases in accordance with the matrix elements may be simultaneously applied to the drive lines of the touch sensor panel.

摘要： Devices having one or more sensors located outside a viewing area of a touch screen display are disclosed. The one or more sensors can be located behind an opaque mask area of the device; the opaque mask area extending between the sides of a housing of the device and viewing area of the touch screen display. In addition, the sensors located behind the mask can be separate from a touch sensor panel used to detect objects on or near the touch screen display, and can be used to enhance or provide additional functionality to the device. For example, a device having a sensor located outside the viewing area can be used to detect objects in proximity to a functional component incorporated in the device, such as an ear piece (i.e., speaker for outputting sound). The sensor can also output a signal indicating a level of detection which may be interpreted by a controller of the device as a level of proximity of an object to the functional component. In addition, the controller can initiate a variety of actions related to the functional component based on the output signal, such as adjusting the volume of the earpiece.

摘要： The fabrication of a touch sensor panel having co-planar single-layer touch sensors fabricated on the back side of a cover glass is disclosed. It can be desirable from a manufacturing perspective to perform all thin-film processing steps on a motherglass before separating it into separate parts. To perform thin-film processing on a motherglass before separation, a removable sacrificial layer such as a photoresist can be applied over the thin-film layers. Next, the motherglass can be scribed and separated, and grinding and polishing steps can be performed prior to removing the sacrificial layer. In alternative embodiments, after the protective sacrificial layer is applied, the bulk of the coverglass can be dry-etched using a very aggressive anisotropic etching that etches primarily in the z-direction. In this embodiment, the etching can be patterned using photolithography to create rounded corners or any other shape. The photoresist can then be removed.

摘要： This relates to adding multi-touch functionality to a display without the need of a separate multi-touch panel or layer overlaying the display. Instead, embodiments of the invention can advantageously utilize existing display circuitry to provide multi-touch functionality while adding relatively little circuitry that is specific to the multi-touch functionality. Thus, by sharing circuitry for the display and the multi-touch functionalities, embodiments of the invention can be implemented at a lower cost than the alternative of superimposing additional multi-touch related layers onto an existing display panel. Furthermore, since the display and multi-touch functionality can be implemented on the same circuit, they can be synchronized so that noise resulting from the display functionality does not detrimentally affect the multi-touch functionality and vice versa.
摘要翻译：这涉及向显示器添加多点触摸功能，而不需要单独的多点触摸面板或覆盖显示器的层。相反，本发明的实施例可以有利地利用现有的显示电路来提供多点触摸功能，同时添加特定于多点触摸功能的相对少的电路。因此，通过共享用于显示器和多点触摸功能的电路，本发明的实施例可以以比将附加的多点触摸相关层叠加到现有显示面板上的替代方案更低的成本来实现。此外，由于可以在相同的电路上实现显示和多点触摸功能，所以它们可以被同步，使得由显示功能产生的噪声不会不利地影响多点触摸功能，反之亦然。

摘要： Normalization of the built-in DC offset error in each analog channel is disclosed to reduce image distortion in multi-event (multi-touch or multi-hover) sensor panels. By eliminating the component-dependent offset error from each analog channel, each analog channel will generate approximately the same output value for a given dynamic input signal. Normalization can include “phantom row” compensation, which involves measuring the static output value of each analog channel when no stimulus is applied to any row of a multi-event sensor panel, and subtracting this value out of any subsequent output value generated by the analog channel. Normalization can also include DAC offset compensation, which involves setting the offset compensation voltage of each analog channel to some fraction of its normal value, measuring the output of the analog channel over temperature, determining a temperature coefficient, and adjusting any subsequent output value generated by the analog channel to account for this drift.
摘要翻译：公开了每个模拟通道内置DC偏移误差的归一化，以减少多事件（多点触控或多悬停）传感器面板中的图像失真。通过消除每个模拟通道的与分量相关的偏移误差，每个模拟通道将为给定的动态输入信号产生大致相同的输出值。标准化可以包括“幻影行”补偿，其涉及当没有刺激施加到多事件传感器面板的任何行时测量每个模拟通道的静态输出值，并且从模拟产生的任何后续输出值中减去该值渠道。归一化还可以包括DAC偏移补偿，其包括将每个模拟通道的偏移补偿电压设置为其正常值的一部分，测量模拟通道的温度输出，确定温度系数，以及调整任何后续的输出值模拟通道来解释这个漂移。
