Patent ID: 7965262

Claim:
A device for displaying images comprising: an image display panel configured such that each image to be displayed is divided into pixels or subpixels having luminous intensity data allocated thereto, said image display panel comprising a first array and a second array of electrodes which serve an array of light-emitting cells, where each light-emitting cell is assigned to a pixel or subpixel of images to be displayed and is powered for light emission between an electrode of the first array and an electrode of the second array effecting between them an intrinsic capacitor C i , power supply means for generating a potential difference between two terminals, and drive means: wherein successively connecting each electrode of the second array to one of the terminals of the power supply means, wherein, during each sequence of connection of an electrode of the second array, simultaneously connecting one or more or all the electrodes of the first array to the other terminal of the power supply means in order to allow said power supply means to power for light emission at least one of the light-emitting cells linked both to the respective electrode of the second array and the respective electrode or electrodes of the first array, wherein, during the sequence of connection of an electrode of the second array, transferring to each light-emitting cell to be powered for light emission charge of the intrinsic capacitors of the other light-emitting cells that are linked to the same electrode of the first array as the light-emitting cell to be powered in order to allow said transferred charge to power for light emission said light-emitting cell, wherein said charge has been accumulated during a just preceding sequence of connection of another electrode of the second array, and wherein during each sequence of connection of an electrode of the second array, the duration of connection t′ a1 of each electrode of the first array to said power supply means and the duration of the transfer of charge t′ a2 of the intrinsic capacitors of the other light-emitting cells linked to the same electrode of the first array are made dependent on a comparison of the luminous intensity datum of the light-emitting cell that is to be powered for light emission between this electrode of the first array and this electrode of the second array with the useful charge Q u that has been accumulated during a just preceding sequence of connection of another electrode of the second array.
