A transparent diffusive OLED substrate includes (a) a transparent flat substrate made of mineral glass having a refractive index of between 1.45 and 1.65, (b) a rough low index layer including mineral particles, the mineral particles being attached to one side of the substrate by means of a sol-gel mineral binder, the mineral particles near, at or protruding from the mineral binder's surface creating a surface roughness characterized by an arithmetical mean deviation Ra comprised between 0.15 and 3 &#x3bc;m, the mineral particles and mineral binder both having a refractive index of between 1.45 and 1.65; (c) a high index layer made of an enamel having a refractive index comprised between 1.8 and 2.1 covering the rough low index layer.

Transparent diffusive oled substrate and method for producing such a substrate

A device for generating a display image on a composite glass pane is described. The device has: a composite glass pane with a first pane and a second pane, which are connected to each other via an intermediate layer that contains at least one luminescent pigment; a laser projector, which contains at least one laser and an optical system for deflecting a radiation of the laser, the radiation being directed within a region of the composite glass pane; a photodetector, which detects luminescent radiation of the luminescent pigment; and a control unit, which electronically connects the photodetector and the laser projector.

Device for generating a display image on a composite glass pane

Method of using a device for displaying a real image of the head-up display (HUD) type in a passenger compartment comprising glazing, notably laminated glazing, said device comprising a source emitting a beam of radiation of the visible UV or IR laser type or of the light-emitting diode type, directed towards a portion of said glazing comprising a fluorescent material absorbing said radiation and re-emitting light in the visible region, the illumination of said portion by the beam enabling a real image to be displayed on the glazing.

Method for implementing a device for displaying a real image

A glazing panel for a display device, includes an external first transparent pane and an internal second transparent pane, each pane including an external face and an internal face, the glass panes being joined together by an interlayer made of a thermoformable material or by a multilayer sheet incorporating such an interlayer; a protective layer made of an opaque material making contact with the internal face of the external first pane; a masking layer made of an opaque material making contact with the internal face of the internal second pane, the masking layer including apertures forming pictograms; and a uniform layer of a material doped with luminescent species chosen because they absorb light radiation produced by the source generating radiation in the UV or IR range, and re-emit light radiation in the visible range, the uniform layer being placed in the glazing panel, between the masking layer and the protective layer.

A transparent diffusive OLED substrate includes the following successive elements or layers: (a) a transparent flat substrate made of mineral glass having a refractive index nof between 1.48 and 1.58, (b) a monolayer of mineral particles attached to one side of the substrate by means of a low index mineral binder having a refractive index nof between 1.45 and 1.61, and (c) a high index layer made of an enamel having a refractive index nbetween 1.82 and 2.10 covering the monolayer of mineral particles, the mineral particles having a refractive index nbetween n+0.08 and n&#x2212;0.08 and protruding from the low index mineral binder so as to be directly in contact with the high index layer, thereby forming a first diffusive interface between the mineral particles and the low index binder, and a second diffusive interface between the mineral particles and the high index layer.

A luminous glazing unit including at least one substrate formed by a transparent glazing element; at least one light source; and at least one light extraction device for extracting the light, the extraction device being arranged to create a luminous region, the extraction device being formed by at least one fibrous layer.

A substrate for an organic light-emitting device, includes a transparent substrate having an optical index n, bearing, on a first main face, a first transparent or semi-transparent coating of an electrode, referred to as the lower electrode, with a sheet resistance less than or equal to 6&#x3a9;/&#x25a1; and which includes the following stack of layers: an anti-reflection sublayer having a given optical thickness Land having an optical index nsuch that the ratio of nto nis greater than or equal to 6/5; a first metallic layer having a given thickness e; a first separating layer, having a given optical thickness L; a second metallic layer, having an intrinsic electrical conductivity property, and having a given thickness e; and an overlayer for adapting the work function, Lbeing between 20 nm and 120 nm, Lbetween 75 nm and 200 nm, and the sum of the thicknesses e+eof the first and second metallic layers being less than or equal to 40 nm.

Substrate for organic light-emitting device, and also organic light-emitting device incorporating it

A transparent substrate including at its surface a grating of parallel lines of patterns separated by zones with a refractive index different from that of the patterns, the grating diffusing light and including at least 4 sub-gratings, each sub-grating including plural blocks of identical patterns with a width, each block including 2 to 10 of the patterns. Centers of gravity of neighboring patterns inside a block are separated by a constant period, the distance between neighboring blocks vary in a non-monotonic manner when passing from one edge of the sub-grating to the other edge of the sub-grating.

Grating comprising sub-gratings with light-diffusing patterns

A method for fabricating a textured single crystal including depositing pads made of metal on a surface of a single crystal. A protective layer is deposited on the pads and on the single crystal between the pads; and etching the surface with a first compound that etches the metal more rapidly than the protective layer is carried out. Processing continues with etching the surface with a second compound that etches the single crystal more rapidly than the protective layer; and etching the surface with a third compound that etches the protective layer more rapidly than the single crystal. The textured substrate may be used for the epitaxial growth of GaN, AlN or III-N compounds (i.e. a nitride of a metal the positive ion of which carries a +3 positive charge) in the context of the fabrication of LEDs, electronic components or solar cells.
