<p>1. Electronic control circuit with N x n outputs used for controlling N x n rows (Lj ) or columns (4) of a matrix device and more particularly a matrix display (2), characterized in that it comprises a multiplexing circuit (16), formed in N groups (G1 , ... Gn ) of n successive thin film transistors (T1 , ... Tn ), a first shift register (18) with N outputs (P1 , ... Pn ) and a second shift register (20) with n outputs (S1 , ... Sn ), the gates of the n transistors (T1 , ... Tn ) of the same group (Gi ) being connected to the same output (Pi ) of the first register, whereby to each group (Gi ) corresponds a different output (Pi ) of said first register (18), the source of each transistor being connected to a different row (Lj ) or column (4), the drain of the ith transistor (Ti ) of each group (Gi ) being connected to the ith output of the second register (20), i being an integer such that 1 =< i =< n.</p> |
