Embodiment Construction

[0031] figure 1 A perspective view of a large-area display system 1 according to the invention is shown schematically. The display system comprises a first display layer 2 consisting of a fabric sheet into which a plurality of individually addressable light sources, here LEDs, are embedded. The sheets are tensioned by a metal frame (not shown) in order to create a flat display layer. The LEDs (also not shown) are attached to the fabric sheet, in which the electrical conductor wires are also included, which are required for powering the individual LEDs.

[0032] A plurality of LEDs are systematically distributed on the sheet so that parallel columns and parallel rows of LEDs can be distinguished. More particularly, the LED columns are arranged parallel to the edge 3 of the display layer and the LED rows are arranged parallel to the edge 4 of the first display layer. The LEDs were arranged such that the distance from each LED to the nearest neighbor LED was about 4 centimeter...

Abstract

The invention relates to a large-area display system (1) comprising a pixelated first display layer (2), which contains a plurality of individually addressable light sources (7) for generating images of a low resolution on the first display layer (2). The system further comprises an at least partly optically transparent second display layer (5) for presenting an image of a high resolution, said second layer being positioned substantially parallel to the first display layer (2). The display system (1) is adapted such that the image of a low resolution and the image of a high resolution are mutually tuned. The invented display systems allow the viewers to perceive an enhanced visional 3D depth in the images produced by the display system.

Description

technical field [0001] The present invention relates to a large area display system comprising a pixelated first display layer containing a plurality of individually addressable light sources for generating a low resolution image through the first display layer. Such large area display systems can be attached to walls, but can also be positioned as (parts of) self-supporting or freestanding notice boards. Background technique [0002] Large-area displays of the type mentioned in the opening paragraph are known per se. More specifically, the international patent application document WO 2011 / 114263-A2 published in the applicant's name describes such a display system, here formed as an architectural element based on luminous textiles. The element comprises a fabric sheet covering an area having a border defined by a frame. The fabric is also tensioned by the frame so that the fabric piece has a flat and uniform surface. The fabric sheet contains a plurality of light sources ...
