  • Patent number: 9195105
    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.
