Abstract
A display arrangement includes a decoration layer, a light source underneath the decoration layer, and a lens layer arranged between the decoration layer and the light source. The decoration layer includes at least one void formed in the shape of a character when viewed from above. The lens layer is at least semi-transparent to permit transmission of light from the light source through the void. An optical structure is arranged in alignment with the void and is adapted to reduce intensity of the light in a peripheral region of the void so as to reduce a halo effect. The decoration layer may be formed as an external layer of a key or a button of a portable electronic device, or an outer casing of a portable electronic device.
