Patent ID: 7388577

Claim:
A display apparatus comprising: a display layer; a plurality of pixel elements arranged on the display layer; and a touch-sensitive layer running parallel to the display layer; wherein a side of the touch-sensitive layer which is remote from the display layer includes an antireflection lattice comprising first lattice elements extending in a first direction parallel to the display layer and second lattice elements extending in a second direction parallel to the display layer and orthogonal to the first direction, the first and second lattice elements intersecting at nodes of the lattice at which the first and second lattice elements can move with respect to one another, the first and second lattice elements forming a plurality of microscopic channels extending in a third direction orthogonal to the first and second directions, the plurality of channels being associated with the plurality of pixel elements for viewing the display layer in the third direction and absorbing or reflecting oblique incident light from the first or second directions.
