A display (20) comprises a first surface comprising an array of pixels (22), the pixels (22) in the array being aligned to define an array x-axis and an array y-axis. The display (20) further comprises a second surface (32) overlying the first surface, the second surface (32) being provided with a coding pattern (40), which comprises marks (46) arranged according to a grid, the grid being arranged to define a grid x-axis and a grid y-axis. The grid x-axis overlies the array x-axis in a manner such that the grid x-axis is offset by an angle with respect to the array x-axis. |
