  • Patent number: 9236705
    Abstract: A good way to avoid extreme current levels when supplying large amounts of power is to increase the voltage. The easiest way to do this is connecting the radiation elements (e.g. laser diode pixels) in series (La1 to La-n). In such a pixelated driver, the amount of components and complexity per pixel are reduced by connecting as many radiation elements as possible in series, supplying the string by one current controlled driver (Is), shortening pixels which should be in off state by a switch in parallel (40-1 to 40-n) to the radiation element, storing binary on/off information (30-1 to 30-n) for each pixel locally, creating a floating supply (20-1 to 20-n) for the switches, and managing information transfer to the floating storage and switches.
