Abstract: Processes for manufacturing touch sensors with one or more guard traces to reduce the effect of moisture damage are provided. One example process can include forming one or more guard traces between an edge of the touch sensor and the metal traces that route the drive and sense lines to bond pads. The one or more guard traces can be uncoupled from the drive lines and sense lines to protect the inner metal traces from moisture damage. In some examples, ends of the one or more guard traces can be coupled to ground by copper. In other examples, ends of the one or more guard traces can be coupled to ground by indium tin oxide or the one or more guard traces can be coupled to ground by a strip of indium tin oxide. In yet other examples, the guard trace can be floating (e.g., not coupled to ground).

Abstract: Integrated touch screens are provided including drive lines formed of grouped-together circuit elements of a thin film transistor layer and sense lines formed between a color filter layer and a material layer that modifies or generates light. The common electrodes (Vcom) in the TFT layer can be grouped together during a touch sensing operation to form drive lines. Sense lines can be formed on an underside of a color filter glass, and a liquid crystal region can be disposed between the color filter glass and the TFT layer. Placing the sense lines on the underside of the color filter glass, i.e., within the display pixel cell, can provide a benefit of allowing the color filter glass to be thinned after the pixel cells have been assembled, for example.

Abstract: A touch sensor panel including artwork formed on the touch sensor panel is disclosed. The touch sensor panel stackup can include a substrate, one or more underlying layers, one or more patterned transparent conductive layers, a passivation layer, artwork, and an adhesive layer. The artwork on the touch sensor panel can be formed by aligning to the touch sensor pattern or alignment marks. In some examples, the artwork can be formed on a discrete touch sensor panel, and the discrete touch sensor panel can be bonded to a cover glass or cover material. In some examples, the touch sensor panel can be a Dual-sided Indium Tin Oxide (DITO) stackup. In some examples, the drive lines and the sense lines of the touch sensor panel can be formed on separate substrates, and the substrates can be bonded together using an adhesive.

Abstract: Compact touch sensors for touch sensitive devices and processes for forming the touch sensors are disclosed. The touch sensor structure can include a substrate, one or more underlying layers disposed on the substrate, one or more blocking layers disposed on the substrate or on one or more underlying layers, and one or more patterned layers disposed on the underlying layers or blocking layers. The one or more blocking layers can be configured to block underlying layers from exposure to certain wavelengths of light or from penetration of a laser beam that can cause damage. Additionally, the one or more underlying layers can be multi-functional, including the ability to block one or more light sources.

Abstract: 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.

Abstract: 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. Groups of 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.
