Embodiment Construction

[0039] The building 2 in FIG. 1 has a plurality of facades on each of its sides, four in this example. One of them contains a set of video image display devices for the facade 4, which is a facade within the scope of the present invention. In particular, this device 6 is visible in FIGS. 2 , 3 and 5 .

[0040] The façade contains a number of building elements, here consisting of windows 8 . These windows extend from top to bottom in the height of the building façade and side to side in its width. The windows are extended one by one in both directions, e.g. most of them lie in the same plane, and if the facade is planar, all the windows lie in the same plane. In particular, each window 8 has two panels 10 , 12 as shown in FIG. 3 . The term "panel" as used herein refers to a transparent plate made of glass. However, such screens can be made of other non-glass materials, eg synthetic materials or plastics.

[0041] Both screens 10 and 12 are flat and identical. Each piece e...

Abstract

The element (8), in particular for an edifice (2), comprises: - two glass panes (10, 12) extending opposite one another to form a double glazing; and - an electronic circuit (13) comprising diodes (18) which is able to display at least a part of a video image by means of the diodes, the circuit extending opposite a visible zone of the glass panes and between the two panes. The element can serve to form a device for video display on a building facade.

Description

technical field [0001] The invention relates to a display panel using light-emitting diodes (LEDs), in particular a display panel of large size that can extend over all or part of a building's facade. Background technique [0002] In the prior art, video image display devices used on building facades transmit display content by means of light-emitting diodes (LEDs). The size of the device can be very large, covering an area of ​​hundreds or even thousands of square meters. Such a display device has the following advantages: firstly it can be integrated into buildings. Therefore, buildings must be able to support such display devices, which extend to great heights utilizing the shape of the building. Diode energy consumption is relatively low. However, even in broad daylight and full sun, they produce images that are clearly visible with remarkable contrast. Diodes allow playback of movies or fast-changing images with superb rendering. Finally, and most importantly, the ...
