20090273570 | MULTI-TOUCH SENSOR PATTERNS AND STACK-UPS - Capacitive multi-touch sensor panels in which both row and column traces may be formed on a single conducting surface are disclosed. These stack-ups may be made thinner and more flexible allowing them to be particularly well-suited for curved or other non-flat touch sensor panels, such as those that might be present on a mouse or other device designed to be grasped by a user's hand. Curved sensor panel arrays that may be formed from flat substrates are also disclosed. These sensor panel configurations may include channels around the periphery of the array. These channels allow the flat array to lie flat when applied to a curved surface, such as the inside of the curved surface. The pattern of the touch sensor elements may be adjusted across the array to avoid the channels. | 11-05-2009 |
20110100727 | Touch Sensitive Device with Dielectric Layer - A touch sensitive device having a dielectric layer between a cover layer and a touch sensor layer is disclosed. The dielectric layer can reduce a negative pixel effect associated with poor grounding of an object touching the device. The dielectric layer can reduce a capacitance per unit area of the device to less than about 0.0305 picofarads per square millimeter, thereby reducing the negative pixel effect. The dielectric layer can have a thickness of about 0.50 millimeters or more and/or a dielectric constant of about 2.3 or less to reduce the negative pixel effect. | 05-05-2011 |
20110128237 | Thinned-Portion Substrates - Thinned-portion substrates and processing of thinned-portion substrates is provided. A portion of a substrate, such as a mother glass used in touch screen manufacturing, can be thinned by forming a cavity in a surface of the substrate. Surface structures, such as touch sensing circuitry and/or display circuitry, can then be formed on the thinned portion of the substrate. For example, touch screen components can be formed as surface structures including touch sensing circuitry and display circuitry on one or more thinned substrate portions through processes including depositing, masking, etching, doping, etc. The thinned substrate portion, including the surface structures formed thereon, can then be detached from the surrounding thicker part of the substrate. In this way, for example, the surrounding thicker part of the substrate can provide structural integrity during various other manufacturing processes, while allowing surface structures to be formed directly on a thinner substrate. | 06-02-2011 |
20110147973 | Injection Molding of Touch Surface - Injection molding for a touch surface of a touch sensitive device is disclosed. A single-shot injection molding method can include molding an injected material to encapsulate a touch sensor at a substantially uniform distance from a touch surface of the molded material. A double-shot injection molding method can include molding a first shot of an injected material to contact a portion of a touch sensor and molding a second shot of an injected material to encapsulate at least the remaining portions of the touch sensor to form a touch surface at a substantially uniform distance from the touch sensor. Another molding method can include molding a coating on a touch sensor to having a substantially uniform thickness. The injection molded material can provide a substantially uniform capacitive dielectric for the device. The injection molded touch surface can be incorporated into an electronic mouse, a mobile telephone, a digital media player, or a computer. | 06-23-2011 |

20130127480 | SINGLE SUBSTRATE CAPACITIVE TOUCH SENSOR WITH INTEGRATED DIELECTRIC AND GROUND SHIELD LAYER - A compact touch sensor and a touch sensor stack are disclosed. The touch sensor can include a touch sensor circuit integrated with a ground layer on a single substrate. The touch sensor circuit can include two sets of conductive traces separated by a first insulation layer. A second insulation layer can be deposited over the top set of conductive traces of the touch sensor circuit. One or more vias can be included within the first insulation layer to route one or more conductive traces through the first insulation layer. One or more vias can also be included within the substrate to couple one or more conductive traces to the grounding layer. The touch sensor can be laminated to a cover material to form the touch sensor stack. Processes for making the touch sensor and touch sensor stack are also disclosed. | 05-23-2013 |

20150123887 | INVISIBLE LIGHT TRANSMISSION VIA A DISPLAY ASSEMBLY - Systems, methods, and computer-readable media for transmitting data using invisible light via a display assembly of an electronic device are provided. This may enable more data to be transmitted simultaneously via a single display assembly of a limited size. For example, a single display assembly may simultaneously transmit a first type of data using visible light that may be comprehensible to a user (e.g., textual information that may be legible to a human) as well as a second type of data using invisible light that may be machine-readable (e.g., a barcode that may be detected by a scanner device but that may not be seen by a human). | 05-07-2015 |
