Scan signal generator for matrix display

摘要

Systems for displaying images. The system comprises a scan signal detector (100A) with X+1 shift registers connected in series, generating X+1 output pulses (S1-Sn+1) in sequence according to a start pulse and a clock signal, and a logic unit (NG1-NG2n) coupled to the X+1 shift registers, generating Z scan signals (G1-G2n) in sequence according to the X+1 output pulses scan and Y enabling signals (ENB1,ENB2), wherein Y, X and Z are integers, Y > 1, X > 0 and Z≥X.
