ABSTRACT:

FIELD OF THE INVENTION
This invention relates to display panels.
More particularly, the invention concerns a display panel comprising:
several displays all having the same format and each having a surface area of at least 2 m
2
,
at least one display surface visible to the public and allowing each display to be displayed,
and an automatic display changing device adapted to show displays successively on the display surface to the public.
BACKGROUND OF THE INVENTION
Existing display panels of this type are well adapted to be visible from a distance in public places (public thoroughfares, airports, stations, shopping centres etc.) and to deliver very short advertising messages, limited for example to an image associated with a brand name and/or a slogan. However these display panels do not allow more detailed information of the corresponding product or service to be given.
OBJECTS AND SUMMARY OF THE INVENTION
This invention is particularly intended to compensate for this drawback.
To this end, according to the invention, a display panel of the said type is essentially characterised:
in that each display comprises in its surface an optically transparent window having a surface area between 5% and 70% of the surface area of the display,
in that the display panel comprises at least one device for displaying images which includes a reserve of several images for each display of the display panel and which is adapted to display these images in the widow of each display (the said images may, if the need arises, be composed at least in part of text, and they may be still or animated),
and in that the display panel moreover comprises control means adapted to display successively in the window of each display, by means of the image display device, the images corresponding to this display (in a predetermined order, or randomly, or yet according to the demands of the public if the display panel is made interactive).
These arrangements make it possible to give detailed information of the product or service displayed in large format on the display, this detailed information being visible to people approaching the panel after their attention has been drawn by the large format display and/or by the movement created by the succession of images displayed in the display window.
In preferred versions of the invention use may possibly be made moreover of one and/or other of the following arrangements:
the surface area of the window is between 10% and 40% or the surface area of the display,
the window is substantially identical and situated in substantially the same place in the various displays,
the image display device includes a screen situated to correspond with the place occupied by the window of each display when this display is shown on the display surface, the reserve images of the display device including at least one animated sequence, and the control means being adapted to display this animated sequence on the screen while the corresponding display is shown,
the reserve images of the image display device include several animated sequences for each display, the control means being adapted to display these animated sequences on the screen while the corresponding display is shown,
the control means are adapted to display different images from among the images corresponding to each display according to the time of day,
the control means are connected to an interface allowing the public to choose the images displayed by the image display device from among the different images displayed on the display surface, the control means being adapted to then display these images by means of the image display device,
the interface also allows the public to choose the display shown on the display surface, the control means being adapted to then show this display on the display surface by means of the display changing device,
the displays are made up of successive portions of a flexible tape, the display changing device being adapted to run this flexible tape past the display surface in order to selectively show one of the displays on this display surface,
the display panel comprises sound transmission means, the control means being adapted to transmit sounds corresponding to the images displayed by the image display device by means of these sound transmission means.
