Abstract
The invention relates to a display screen and its manufacturing process. The display screen of the invention comprises: a substrate made of a plastic; at least one transparent heating element; and at least one thermochromic compound, and is characterized in that the at least one transparent heating element comprises at least one optionally functionalized metal nanowire. The invention in particular has applications in the electronics industry.
Claims23
A display screen, comprising:
- a substrate made of a plastic material;
- at least one transparent heating element;
- and
- at least one thermochromic compound,
- wherein said at least one transparent heating element comprises at least one metal nanowire which is functionalized and comprises, at an external surface, a self-assembled monomolecular layer formed from one or more precursor of molecule of formula I,
- R1—Zn—R2 Formula I
- in which:
- Z represents a sulfur or selenium atom,
- n=I or 2,
- R1 and R2 each represent, independently of one another, a hydrogen atom or a saturated or unsaturated and linear, branched or cyclic hydrocarbon group which is optionally perfluorinated or partially fluorinated, which comprises from 1 to 100 carbon atoms and which optionally comprises one or more heteroatoms and/or one or more chemical functional groups comprising at least one heteroatom and/or one or more aromatic or heteroaromatic groups, or a chemical functional group comprising at least one heteroatom or one aromatic or heteroaromatic group which is substituted or unsubstituted.
7 more elements
A method for the manufacture of a display screen, said method comprising:
- depositing, over all or part of a surface of a substrate made of a plastic material, of at least one heating element comprising at least one metal nanowire, the nanowire being functionalized by formation of a self-assembled monomolecular layer from at least one molecule of formula I,
- R1—Zn—R2 Formula I
- in which:
- Z represents a sulfur or selenium atom,
- n=1 or 2,
- R1 and R2 each represent, independently of one another, a hydrogen atom or a saturated or unsaturated and linear, branched or cyclic hydrocarbon group which is optionally perfluorinated or partially fluorinated, which comprises from 1 to 100 carbon atoms and which optionally comprises one or more heteroatoms and/or one or more chemical functional groups comprising at least one heteroatom and/or one or more aromatic or heteroaromatic groups, or a chemical functional group comprising at least one heteroatom or one aromatic or heteroaromatic group which is substituted or unsubstituted.
