Abstract

A lenticular antireflection screen for an electronic display. A lens sheet is arranged in juxtaposition with the display surface of an electronic display. There may or may not be an air gap between the lens sheet and the display surface. The lens sheet has a thickness that is proportional to the pitch of the lenticules. The front surface of the lens sheet includes lenticules oriented at an angle other than 90 degrees relative to a horizontal edge of the lens sheet. The optimum angle for a particular display can be determined by rotating the lens sheet in front of the display and observing when reflections are minimized. In an alternative arrangement, the rear surface of the lens sheet includes concave lenticular elements with a negative diopter power.

Claims

1. A lenticular antireflection display, comprising:

a display surface; and

a lens sheet coupled over the display surface and having a plurality of lenticules disposed thereon, wherein the lenticules are disposed on the lens sheet at an angle other than 90 degrees relative to a horizontal edge of the lens sheet.
