Display arrangement with optical structure for reducing halo effect

摘要

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.

主权项

1. A display arrangement, comprising:
a decoration layer comprising a top surface, a bottom surface, and at least one void between the top and bottom surfaces, the void comprising a central region and a peripheral region adjoining the central region; a light source arranged underneath the bottom surface of the decoration layer, the light source adapted to transmit light through the void; and a lens layer arranged generally between the decoration layer and the light source, the lens layer being at least semi-transparent to permit transmission of the light through the void, the lens layer comprising an optical structure arranged in alignment with the void, wherein the optical structure directs light away from the peripheral region of the void to reduce intensity of the light in the peripheral region, and wherein the optical structure comprises at least one angled face arranged to refract the light away from the peripheral region.
