Abstract:
1. Device for individually driving OLED/LED elements of an OLED/LED string, comprising for each OLED/LED element of the string: a controllable shunting switch coupled with the respective OLED/LED element, switch controller means for controlling said shunting switch and having a control output port coupled to said switch, a data input port and a clock input port, and level shifting means assigned to said switch controller means and adapted to bring the control input data to a level sufficient to be accepted by the switch controller means during a programming mode and to allow the control of said shunting switch, wherein said switch controller means of said modular units are coupled in series to shift the control input data to the switch controller means of the respective subsequent modular unit and to form a serial-to-parallel converter means, wherein said switch controller means is a D-latch circuit triggered via said clock input port (CLK).
