MANUFACTURING PROCESS OF A VERY HIGH RESOLUTION DISPLAY HAVING AN ANISOTROPIC LIGHT-EMITTING CONDUCTIVE FILM BASED ON LIGHT-EMITTING DIODE NANOWIRES AND CORRESPONDING DISPLAY

摘要

A method for producing an emissive pixel screen includes forming an active pixel matrix along which an electrode forming layer runs and having pixels arranged according to a distribution, forming an anisotropic substrate that includes a set of light emitting diodes constituted by parallel nanowires and arranged in an insulating matrix transversely with respect to a substrate thickness and having a density higher than a density of the pixels irrespective of the pixel distribution, connecting the substrate to the active pixel matrix by connecting only sub-groups of the parallel nanowires by a first end to separate pixel electrodes defined in the electrode forming layer according to the distribution of the pixels in the matrix, and connecting the sub-groups, by another end, to a common electrode, and delimiting the sub-groups by rendering the nanowires of the substrate that are arranged between the sub-groups emissively inactive.
