Abstract
Abstract A display arrangement for displaying an image for a viewer on the basis of at least two variables for each picture element such as picture element position and picture element information. In known display arrangements of this type, the whole image is produced at one and the same place by means of one image display element. According to the invention, the display arrangement is divided into two display elements arranged at a distance from one another. By not producing the whole image at one and the same place, an individual image can be displayed to different viewers and it can be prevented that an unauthorised viewer receives information of interest. Due to the dividing up, each display element can be made compact (Figure 1).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
87 words
Display arrangement for displaying an image for a viewer on the basis of at least two variables for each picture element such as picture element position and picture element information, characterised in that the display arrangement is divided into a first and a second display element arranged at a distance from one another and provided with means for mutual synchronisation, each display element of the display arrangement reproducing at least one variable each, and the second display element being arranged in the immediate vicinity of the viewer.
Claim 2
Dependent Claim
54 words
Display arrangement according to Claim 1, each picture element in an image being displayed on the basis of three variables, namely two angle distributions and a picture element information, characterised in that the first display element generates picture element information and one angle distribution whilst the second display element generates the second angle distribution.
Claim 3
Dependent Claim
50 words
Display arrangement according to Claim 1, each picture element in an image being presented on the basis of three variables, namely two angle distributions and a picture element information, characterised in that the first display element generates picture element information whilst the second display element generates the two angle distributions.
Claim 4
Dependent Claim
51 words
Display arrangement according to Claim 1, each picture element in an image being displayed on the basis of three variables, namely two angle distributions and a picture element information, characterised in that the first display element generates the two angle distributions whilst the second display element generates the picture element information.
Claim 5
Dependent Claim
55 words
Display arrangement according to Claim 1, each picture element in an image being displayed on the basis of three variables, namely two angle distributions and a picture element information, characterised in that the first display element generates one angle distribution whilst the second display element generates the other angle distribution and the picture element information.
Claim 6
Dependent Claim
34 words
Display arrangement according to any of the preceding claims, characterised in that the second display element is supplied with variables which are individually adapted for producing an individually adapted image for the respective viewer.
Claim 7
Dependent Claim
30 words
Display arrangement according to any of the preceding claims, characterised in that two part images constituting a pair of stereo images are supplied to the two eyes of the viewer.
Claim 8
Dependent Claim
51 words
Display arrangement according to any of the preceding claims, characterised in that each image is generated by a single picture element or several parallel picture elements with mutual stationary positions which generate a complete series of images or part-images within the integration time of the eye or eyes of the viewer.
