Abstract (en)
[origin: WO2016008677A2] The invention relates to a circuit arrangement for addressing LEDs in a matrix configuration having m columns and n rows, wherein each LED (LED11, LED12, LED21, LED22) of the matrix can be individually addressed by the actuation of a corresponding column driver (S01, S02) in conjunction with the actuation of a corresponding row driver (S10, S20), with a bias system (12) for each row. The bias system (12) comprises a first bias connection (14) for electrically coupling to the cathodes of m LEDs (LED11, LED12) of the row and a second bias connection (16) for electrically coupling to the anodes of m LEDs (LED11, LED12) of the row, each LED (LED11, LED12, LED21, LED22) of the matrix being coupled to the connection of a column addressing system (S01, S02) by respective semiconductor diodes (D11, D12, D21, D22), and in addition, n semiconductor diodes (D11, D21) associated with the same column are each electrically interconnected at one of their respective electrodes. The invention further relates to a display device and to a household appliance having such a circuit arrangement, and to a method for addressing LEDs in a matrix configuration.
