Pixel-aligned diamond-patterned micro-wire electrode
A display device includes a display having an array of pixels separated by inter-pixel gaps in at least one dimension. An electrode having a length direction is formed over the display and extends across at least a portion of the array of pixels. The electrode includes a plurality of electrically connected micro-wires formed in a micro-pattern. The micro-pattern has a first set of parallel micro-wires oriented at a first angle non-orthogonal to the length direction and a second set of parallel micro-wires oriented at a second angle non-orthogonal to the length direction different from the first angle. The micro-wires of the first and second sets intersect to form an array of electrically connected micro-wire intersections. At least every other micro-wire intersection on the micro-wires of the first set is located between the pixels in the inter-pixel gaps.
