Display apparatus with diamond-patterned micro-wire electrode

摘要

A display apparatus includes a display having an array of pixels separated by inter-pixel gaps and a touch screen. The touch screen includes a dielectric layer located over the display having first and second electrodes each having a length direction and extending across at least a portion of the array of pixels. Each electrode includes a plurality of electrically connected micro-wires formed in a micro-pattern. The micro-patterns each have 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.

1. A display apparatus, comprising:
a display having an array of pixels, the pixels separated by inter-pixel gaps in at least one dimension; and a touch screen including:
a dielectric layer located over the display having a first side and a second side opposed to and substantially parallel to the first side, the second side adjacent to the display;a plurality of first electrodes having a first length direction formed over the first side and extending across at least a portion of the array of pixels, each first electrode including a plurality of electrically connected micro-wires formed in a first micro-pattern;a plurality of second electrodes having a second length direction orthogonal to the first length direction formed between the dielectric layer and the display and extending across at least a portion of the array of pixels, each second electrode including a plurality of electrically connected micro-wires formed in a second micro-pattern; andwherein the first micro-pattern has a first set of parallel micro-wires oriented at a first angle non-orthogonal to the first length direction and a second set of parallel micro-wires oriented at a second angle non-orthogonal to the first length direction different from the first angle, the micro-wires of the first and second sets intersecting to form an array of electrically connected first micro-wire intersections;wherein the second micro-pattern has a first set of parallel micro-wires oriented at a first angle non-orthogonal to the second length direction and a second set of parallel micro-wires oriented at a second angle non-orthogonal to the second length direction different from the first angle, the micro-wires of the first and second sets intersecting to form an array of electrically connected second micro-wire intersections; andwherein at least every other first or second micro-wire intersection is located between the pixels in the inter-pixel gaps; andwherein at least one of the micro-wires of the first set and one of the micro-wires of the second set of the first or second micro-pattern covers a portion of one or more pixels.
