ABSTRACT:
A display system for providing a user viewable visible image, includes a view screen for receiving organic laser light and having a diffusing optical element so that the view screen, in response to organic laser light, produces a viewable visible image, wherein the diffusing optical element includes a viewing angle greater than 160° in a first viewing direction and greater than 100° in a second viewing direction orthogonal to the first direction; one or more organic laser light sources arranged in an array with each such laser light source including a vertical cavity design and means for projecting and modulating the intensity of the organic laser light from the array onto the view screen in a pattern to cause a visual image to be produced by the view screen; and means associated with the view screen for reducing speckle in the organic laser light.
