Embodiment Construction

[0026] The figures show an autostereoscopic display 1 which corresponds to some extent to the autostereoscopic display disclosed in DE 10 2005 029 431 A1, to which reference is therefore made, in order to avoid repetition, the content of which is hereby incorporated in its entirety.

[0027] The autostereoscopic display 1 has an OLED backlight 2 , a lenticular grid 3 and an LCD display 4 , which are in each case constructed in a planar manner and arranged in layers parallel and one in front of the other.

[0028] OLED backlighting 2 has many parallel light strip groups 5 (see Figure 4 ), wherein, in different single cases, each of the respective light strip groups 5 has a pair of parallel light strips 6 and 7 for illuminating different eyes of the viewer.

[0029] However, it is also possible that each of the individual light strip groups 5 has multiple pairs of light strips to enable multi-user operation. This means that accordingly multiple viewers receive a three-dimensio...

Abstract

The invention relates to an autostereoscopic display (1) comprising a background illumination (2) with a multiplicity of parallel light strip groups with in each case at least two parallel light strips (6, 7), wherein the individual light strip groups are arranged next to one another with a first grid dimension, and a lens grid (3), which is arranged before the background illumination (2) and has a multiplicity of parallel lens strips (8), wherein the lens strips are arranged next to one another with a second grid dimension, as well as a light modulator (4), which is arranged before the lens grid (3) and displays image information. It is suggested that the first grid dimension of the background illumination (2) differs from the second grid dimension of the lens grid (3).

Description

technical field [0001] The present application relates to an autostereoscopic display according to the preambles of the main claim. Background technique [0002] Stereoscopic image reproduction devices are known in the art and present the viewer with a three-dimensional visual impression by presenting to the viewer's eyes different images recorded from slightly offset perspectives. What is important here is the image separation between the images for both eyes of the viewer, so that the viewer receives a three-dimensional visual impression. One possible way of image separation is for the viewer to wear polarized glasses with polarized filters oriented differently for both eyes. Another possible way of image separation is for the viewer to wear red / green glasses. In a stereoscopic image reproduction device of this type, the viewer must therefore wear glasses in order to achieve image separation, which is not desired. [0003] Furthermore, autostereoscopic image reproductio...
