  • Publication number: 20180088735
    Abstract: Location-based swing compensation for touch sensor panels can improve touch sensing performance. Due to differences in impedance characteristics of touch nodes at different locations in a touch sensor panel (due to differences in routing to touch nodes and due to differences in impedance with respect to ground (loading effects) of touch nodes), touch nodes can have non-uniform bandwidth characteristics which can manifest as non-uniform signal and signal-to-noise ratio (SNR) across the touch sensor panel. Additionally, the non-uniform signal can reduce the effectiveness of bootstrapping. Swing compensated stimulation signals can be applied to various touch nodes based on location and/or impedance characteristics of the various touch nodes. For example, the stimulation voltage can be increased for touch nodes with longer and/or thinner routing traces so that the signal at the touch node can be uniform with other touch nodes whose routing may be shorter and/or thicker.

  • Publication number: 20180067584
    Abstract: Touch sensor configurations for reducing electrostatic discharge events in the border area of a touch sensor panel is disclosed. Touch sensors (e.g., electrodes formed on the cover material and/or the opaque mask) can be susceptible to certain events such as arcing and discharge/joule heating, which may negatively affect touch sensor performance. Examples of the disclosure can include increasing the trace width, spacing, and/or thickness in the border area relative to the trace width, spacing, and/or thickness in the visible/active area along one or more sides of the touch sensor panel. In some examples, touch electrodes can be located exclusively in the visible/active areas along one or more sides of the touch sensor panel, while dummy sections can be included in both the border and visible/active areas. Additionally or alternatively, one or more gaps between adjacent touch electrodes in the border area or serpentine routing can be included.

  • Patent number: 9733331
    Abstract: Roll-to-roll processes for manufacturing touch sensors on a plastic base film are provided. The touch sensors can be deposited on the base film using various patterning techniques. One or more shorting bars can also be patterned onto the base film to couple together traces, such as drive lines, sense lines, conductive traces, and the like, of the touch sensor to prevent a potential difference from forming between traces due to static buildup during the manufacturing process. After the touch sensor is fully formed on the base film, the touch sensor can be removed from the base film using lithography or a physical cutting process. The removal process can separate the touch sensor from the one or more shorting bars, thereby uncoupling the traces of the touch sensor.

  • Patent number: 9703422
    Abstract: A touch sensitive device that detects the occurrence of an electrostatic discharge event on the device by analyzing one or more ESD sensors located in various locations on the touch sensitive device is provided. A touch controller can scan touch nodes on the touch sensitive device while simultaneously scanning one or more ESD sensors to detect if a possible ESD event has occurred during the acquisition of a touch image. If an ESD event has occurred during the acquisition of touch data, the touch controller can act to either ignore the data, or compensate the data to account for effects on the touch data caused by the ESD event.

  • Patent number: 9693043
    Abstract: The invention provides a lenticular lens type three-dimensional image display device and a method of fabricating the device without a need for a clear plastic substrate transposed between the image and lenticular lenses. The device can be obtained by directly printing curable coatings onto the image, making them particularly well suited for volume production. The combination the image printing and application of curable coatings process can be joined together to conduct the single pass-process. The single pass-process allows for flexibility of the printing only selective areas of the substrate. Moreover, this process allows the device to be recyclable.

  • Publication number: 20170167959
    Abstract: A system for automating load conditions on a test specimen includes a test equipment assembly that includes one or more test components configured to apply load to the test specimen. The system includes a control system to actuate the load, and includes a controller that receives and transmits data to sensors and actuators operatively connected to the test equipment assembly. The system includes a data analyzer connected to the control system to transmit a loading sequence to the controller for actuating the test equipment assembly. The data analyzer receives and processes the data from the controller to determine whether the test specimen is within an acceptable stress range as the test equipment assembly performs the loading sequence, and transmits data to the controller to reduce the load on the test specimen if the acceptable stress range is exceeded.

  • Publication number: 20170083152
    Abstract: Electrode configurations for reducing wobble error for a stylus translating on a surface of a touch sensor panel is disclosed. Electrodes associated with a more linear signal profile can correlate to lower wobble error. In some examples, electrodes can be configured such that the signal profile associated with each electrode is spread to be wider, and thus, more linear. In some configurations, electrodes can include two or more bars extending along the length of the electrode with each bar electrically connected to one another at one or both ends. Bars can be of non-uniform width or spacing. Some configurations can include a “split bar,” which can divide a bar lengthwise in order to improve optical uniformity. In some examples, electrodes can include projections which can interleave with corresponding projections in adjacent electrodes.

  • Publication number: 20160313858
    Abstract: Touch sensor panel configurations for reducing wobble error for a stylus translating on a surface over and between electrodes of the touch sensor panel are disclosed. In some examples, electrodes with more linear signal profiles are correlated with lower wobble error. In some examples, diffusing elements formed of floating segments of conductive materials can diffuse signal from a stylus to a plurality of electrodes, thus, making the signal profiles associated with the electrodes more linear. In addition, diffusing elements can be configured to improve the optical uniformity of the touch sensor panel. In some examples, the diffusing elements can be formed on the same layer as floating dummy pixels and resemble a plurality of merged floating dummy pixels.

  • Patent number: 9459738
    Abstract: A touch sensor panel which has been calibrated to be insensitive to effects from an external force applied to the panel is provided. Touch sense circuitry settings are adjusted during a calibration procedure so that when a force is exerted on the device, no change in the touch signal DC level is seen. In this way, the ability of the touch sensor panel to detect touch or proximity events is not affected by a force being applied to the panel.
