摘要： When a user operates a touch sensor panel having an LCD device outdoors or in a bright environment, light reflecting off the device can create glare. In order to reduce glare, a user can view the device through polarized filters such as polarized sunglasses.Doing so can reduce the visibility of the image displayed on the LCD. A quarter-wave retardation film can be added to the touch sensor panel's LCD device to mitigate these effects by producing circularly polarized light. However, adding a separate quarter-wave retardation film can increase the thickness and cost of manufacturing the touch sensor panel. Embodiments of the present disclosure are directed to a touch sensor panel constructed from a base film having quarter-wave retardation properties that can produce circularly polarized light. Because the base film has the desired optical properties, a separate quarter-wave retardation film may not be needed.

摘要： The described embodiments relate generally to the singulation of circuits and more particularly to a method of cutting of a polymer substrate that is overlaid with a conductive element and a passivation layer. In one embodiment, the passivation layer is applied selectively to the polymer substrate in an area covering the conductive element and extending at least a first distance past an outer edge of the conductive element. Then, a cutting operation is performed along a cutting path located a second distance from an outer edge of the passivation layer. The second distance is a minimum distance between the edge of the passivation layer and the cutting path that prevents a load applied at the second distance from causing a stress crack in the passivation layer.

摘要： The formation of improved reliability conductive traces in touch sensor panels that are less prone to failures due to environmental effects is disclosed. Conductive traces, which can be formed from a stackup of metal layers or a single metal layer, can be protected with an additional photoimageable passivation layer of a material such as an organic polymer. This photoimageable coating can be patterned so that it does not appear in the visible area of the touch sensor panel, with much finer tolerances than conventional passivation layers to help keep product dimensions to a minimum.

摘要： A touch screen including display pixels with capacitive elements is provided. The touch screen includes first common voltage lines connecting capacitive elements in adjacent display pixels, and a second common voltage line connecting first common voltage lines. The pixels can be formed as electrically separated regions by including breaks in the common voltage lines. The regions can include a drive region that is stimulated by stimulation signals, a sense region that receives sense signals corresponding to the stimulation signals. A grounded region can also be included, for example, between a sense region and a drive region. A shield layer can be formed of a substantially high resistance material and disposed to shield a sense region. A black mask line and conductive line under the black mask line can be included, for example, to provide low-resistance paths between a region of pixels and touch circuitry outside the touch screen borders.

摘要： Systems and methods are directed to reducing surface reflections on an electronic display device having a touch-screen panel. A touch-screen panel may contribute to undesirable reflection of external light. For example, a touch-screen panel typically includes conductive electrodes which may significantly reflect ambient light, resulting in decreased visibility of displayed images. In some embodiments, a circular polarizer is disposed over a touch-screen panel in the display device. The circular polarizer includes a linear polarizer and a quarter-wave plate to modify the polarization of the external light traveling towards and reflecting from the touch-screen panel and absorbing the reflected light from the touch-screen panel to significantly reduce undesirable light reflections from the touch-screen panel.
