  • Patent number: 8736802
    Abstract: A liquid crystal display (LCD) is provided that comprises a rearward LCD substrate sheet that has an array of vias formed, where the vias provide electrical conduction between both sides of the rearward LCD substrate sheet. The number of vias in the array is substantially equal to or at least equivalent to a combination of a number of column drive lines and a number of row drive lines. The respective drive lines are connected to a corresponding via, such as on one side of the rearward LCD substrate sheet, and respective patterned conductors are connected to a corresponding via, such as on the other side of the rearward LCD substrate sheet. The patterned conductors provide a connection between respective drive lines and one or more corresponding drivers. In one example, this allows a “full bleed” display to be generated.

  • Patent number: 8711108
    Abstract: A substantially transparent touch sensor panel having co-planar single-layer touch sensors and traces fabricated on a single side of a substrate for detecting single or multi-touch events. The touch sensor elements can be fabricated in columns and rows, with each sensor element in a row adjacent to a sensor element in a column. By using a board as the dielectric to connect traces from multiple sensor elements in each row, rather than using a dielectric layer on the substrate upon which the sensor elements and traces are formed, the sensor elements and traces on the substrate can be formed by simply patterning a single layer of conductive material on the substrate, which can simplify the manufacturing process of the substrate from a complexity and cost perspective.
