  • Patent number: 8749596
    Abstract: A pixel with variable chromatic coordinates comprises a plurality of color sub-pixels consisting of a light emitter and a color filter. The light emitters are identical and have an emission spectrum that is able to be modulated according to their supply voltage and/or current. The pixel control circuit supplies each color sub-pixel with a supply voltage and/or current dependent on the color of the sub-pixel for its emission spectrum to approximate the transmission spectrum of the associated color filter. Control means enable the application time of the supply voltage and/or current to be modified according to the color of the sub-pixel to obtain a predetermined mean luminance during a predetermined period.

  • Patent number: 7652260
    Abstract: The particle detection circuit comprises a plurality of basic circuits. Each basic circuit comprises a particle detector element connected to an associated counter and a summing circuit having a first input connected to the output of the counter. Basic circuits, each forming a subpixel, are grouped together by series connection of their summing circuits to form a pixel. The output of the pixel, formed by the output of the summing circuit of a last basic circuit of the pixel, supplies counting signals representative of the number of particles detected by the set of basic circuits of the pixel. Disabling certain basic circuits of the pixel, by selective zero resetting of the first input of their summing circuit, can enable only the particles detected by certain zones of the pixel to be counted.
