1. An apparatus that comprises:

  • a touch sensor that comprises a mesh of conductive material configured to extend across a display, wherein;

    the mesh comprises a plurality of first lines and a plurality of second lines of conductive material, wherein;

    the first lines are substantially parallel to each other; and

    the second lines are substantially parallel to each other;

    the display comprises a plurality of pixels that each comprise sub-pixels, wherein;

    each of the pixels has a first pixel pitch (PPx) along a first axis and a second pixel pitch (PPy) along a second axis that is substantially perpendicular to the first axis;

    each of the sub-pixels has a first sub-pixel pitch (SPPx) along the first axis; and

    each of the sub-pixels has a complex shape that has an average sub-pixel dimension (SPDy,AVG) along the second axis;

    the first lines are configured to extend across the display at a first angle relative to the first axis, wherein the first angle is approximately equal to the arctangent of
