Abstract:
The invention relates to an image display device comprising an imaging matrix, which consists of imaging elements which are arranged in a lateral manner, for example, lenticulars or a lens array, and a plurality of point elements which are disposed on a object plane and which are formed from the imaging elements in an observation chamber. In order to reduce imaging errors resulting in the image field curvature of the individual imaging elements of a large observation angle, compensation by a correction matrix, which contains a plurality of optical corrections elements, takes place. An optical correction element is associated with each individual optical imaging element. Said invention can be used, for example, in image or video display devices, such as autostereoscopic displays, multi-user-displays with sweet-spot-units and multi-view-displays, in order to image illuminating elements. The invention also relates to displays comprising a sweet-spot-unit, which can be switched for one or more observers into a two-dimensional mode and also in an autostereoscopic mode.
