Glass panel for display system

1. A glazing for information display comprising an assembly of two transparent sheets, consisting of inorganic glass or of plastic, the two sheets being connected together by a thermoplastic or adhesive interlayer or by multilayer sheets incorporating such an interlayer, at least one luminophore material enabling said display being incorporated into said glazing, wherein at least one of said luminophore materials comprises a benzene ring substituted at least by:

at least a first ester —COOR group, wherein R is a linear or branched carbon-based group comprising a main carbon-based chain of at least eleven carbon atoms bonded to one another consecutively, and

two hydroxyl —OH groups.

2. The glazing as claimed in claim 1 , wherein said benzene ring is substituted by a second —COOR′ group, wherein R′ is another hydrocarbon-based group or hydrogen.

3. The glazing as claimed in claim 1 , wherein one of said luminophore materials comprises a benzene ring substituted by four groups, including:

two ester groups, respectively —COOR and —COOR′; R and R′ being linear or branched carbon-based groups comprising a main carbon-based chain of at least eleven consecutively bonded carbon atoms, and

two hydroxyl —OH groups.

4. The glazing as claimed in claim 2 , wherein R and R′ are identical carbon-based groups.

5. The glazing as claimed in claim 2 , wherein R and R′ are linear carbon-based groups, the linear carbon-based groups in R and R′ comprising at least eleven successive carbon atoms.

6. The glazing as claimed in claim 1 , wherein said luminophore is a dialkyl 2,5-dihydroxyterephthalate corresponding to the structural formula:

7. The glazing as claimed in claim 1 , wherein said luminophore is a dialkyl 2,5-dihydroxyterephthalate corresponding to the structural formula;

8. The glazing as claimed in claim 1 , wherein the interlayer is made of thermoplastic and wherein said luminophore is dispersed in said thermoplastic.

9. The glazing as claimed in claim 1 , wherein the thermoplastic constituting said interlayer is selected from the group consisting of PVBs, plasticized PVCs, polyurethane PU and ethylene/vinyl acetates EVAs.

10. A motor vehicle or aviation windshield consisting of glazing as claimed in claim 1 , comprising an assembly of two transparent sheets, consisting of inorganic glass or of strong plastic, connected together by a thermoplastic or adhesive interlayer.

11. A glazing for a building, in particular a store window, a spandrel glass or a dividing wall or partition, as claimed in claim 1 .

12. A device for displaying an image on transparent glazing, comprising glazing as claimed in claim 1 and a source configured to generate concentrated excitation radiation of diode type, the radiation of which is between 350 and 410 nm, the excitation radiation being directed toward an area of the glazing comprising the luminophore material.

13. The glazing as claimed in claim 1 , wherein the two hydroxyl groups are in para position on the benzene ring.

14. The glazing as claimed in claim 2 , wherein said second group is in para position on the benzene ring with respect to said first ester group.

15. The glazing as claimed in claim 3 , wherein the two ester groups, respectively —COOR and —COOR′, of the benzene ring substituted by four groups are in para position on the benzene ring, and wherein the two hydroxyl groups of the benzene ring substituted by four groups are in para position on the benzene ring.

16. The glazing as claimed in claim 5 , wherein R and R′ are linear carbon-based groups comprising between 11 and 15 successive carbon atoms.

17. The motor vehicle or aviation windshield as claimed in claim 10 , wherein the strong plastic is PMMA or polycarbonate.

18. The device as claimed in claim 12 , wherein the diode is a laser diode.
