Line spacing in mesh designs for touch sensors

An apparatus comprising:

• a touch sensor comprising a mesh of conductive material, wherein:
• the mesh comprises a plurality of first lines and a plurality of second lines of conductive material extending across a display, the first lines being substantially parallel to each other, the second lines being substantially parallel to each other, the display comprising a plurality of pixels, each of the pixels having a first pixel pitch (PPx) along a first axis and a second pixel pitch (PPy) along a second axis that is perpendicular to the first axis, the first pixel pitch being equal to a distance between corresponding features of two adjacent pixels along the first axis, the second pixel pitch being equal to a distance between corresponding features of two adjacent pixels along the second axis;
• the first lines extend across the display at a first angle relative to the first axis;
• the second lines extend across the display at a second angle relative to the first axis;
• first lines that are adjacent to each other are separated from each other along the first axis by a first-line separation distance that is within 3% of k×3×PPx, wherein k is a positive integer;
• and
• second lines that are adjacent to each other are separated from each other along the first axis by a second-line separation distance that is within 3% of

• one or more computer-readable non-transitory storage media coupled to the touch sensor and embodying logic that is configured when executed to control the touch sensor.
