| 摘要 |
The present invention relates to a 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 (22, 42) coupled with the respective OLED/LED element (14, 15), switch controller means (30, 44) for controlling said shunting switch (22, 42) and having a control output port coupled to said switch (22, 42), a data input port and a clock input port, level shifting means (32) assigned to said switch controller means (30, 44) and adapted to bring the control input data to a level sufficient to be accepted by the switch controller means (30, 44) during a programming mode and to allow the control of said shunting switch (22, 42). Said switch controller means (30, 44) of said OLED/LED elements (14, 15) are provided to form a serial-to-parallel converter means (31).
