Abstract:
La présente invention propose un vitrage multiple à diffusion variable par cristaux liquides (100), présentant des première et deuxième feuilles de verre plan flotté (1, 2) scellées sur le bord de leurs faces internes (11, 21 ) par un joint de scellement (7), notamment en une matière de scellement donnée, notamment, essentiellement organique, des première et deuxième électrodes (3, 4), une couche (5) de cristaux liquides d'épaisseur moyenne E comprise entre 15 et 60 μηη en incluant ces valeurs et incorporant des espaceurs (6). L'épaisseur A de chacune des première et deuxième feuilles de verres est inférieure ou égale à 5,5 mm et chacune des faces internes revêtues des première et deuxième électrodes présentent une note de défauts dioptriques, exprimée en millidioptrie, inférieure à 12E/ 15 ou l'épaisseur E de cristaux liquides est en μm. L'invention concerne aussi le procédé de fabrication d'un tel vitrage
Abstract:
There is provided a wearable display comprising a light source emitting light of a first wavelength; a first SBG device having a front side and a rear side; first and second transparent plates sandwiching said SBG device; independently switchable transparent electrode elements applied to the opposing surfaces of said transparent plates, a means for spatio-temporally modulating light from the light source to provide image light and a means for coupling the image light into the light guide formed by the two transparent plates and the SBG device. The SBG device comprises a multiplicity of selectively switchable grating regions. The SBG device diffracts image into the pupil of an eye.
Abstract:
This invention concerns a method of manufacturing a display and a display. The method comprises providing a substrate (11, 111) having a first electrode (12, 112) formed thereon and coated with physically stabilised liquid crystal layer (13) and printing a second transparent electrode (20) over the physically stabilised layer (13). A dielectric layer (119) may be formed between the physically stabilised liquid crystal layer (13) and the second electrode (20), preferably having a dielectric strength of more than 2V/μm. A barrier layer (110) may be provided to restrict migration of liquid crystal from the liquid crystal layer. The method may comprise performing a wash of the second electrode to remove corrosive materials left over from printing of the second electrode.
Abstract:
The present invention describes a film structure which comprises a plurality of microcups and the microcups are filled with a liquid composition and top-sealed with a sealing layer which is hardened in situ. The liquid composition may be a display fluid or a pharmaceutical composition. The present invention is directed to a liquid crystal display, a display device and a transdermal delivery system.
Abstract:
An electro-optical switch, which can be switched between a substantially transparent state and a scattering state on basis of respective applied voltages, is disclosed. The electro-optical switch has a reflection- voltage curve that is steep enough to allow multiplexing. The electro-optical switch comprises: a scattering layer (302) comprising a liquid crystal-polymer composite; and a reflective layer (306) for reflecting a portion of scattered light back towards the scattering layer (302).
