1. A touch screen having reduced Moiré
- effects, comprising;
a display device, the display device having an array of subpixels of different colors, the subpixels of each color linearly aligned in a first orientation; and
a touch sensor panel at least partially superimposed over the display device, the touch sensor panel having a plurality of substantially transparent first lines and a plurality of substantially transparent second lines forming a capacitive sensor array on a substantially transparent substrate;
wherein the plurality of first lines are non-parallel with respect to the first orientation.

Abstract
Touch screens that generate reduced Moiré effects are disclosed. To reduce Moiré effects, the columns (drive or sense lines) of a touch sensor panel can be oriented at an angle with respect to a display device so that the columns are not parallel with the sub-pixel and pixel arrangements of the display device. In some embodiments, the entire touch sensor panel can be oriented at an angle with respect to the display device. In other embodiments, certain lines in the touch sensor panel can be tilted, curved or formed in a zig-zag shape.
