Abstract :
A multi-line addressing technique that is based on sparse orthogonal matrices is proposed to drive the liquid crystal displays (LCDs). Hardware in the column drivers is utilized fully and yet the hardware complexity of the controller is reduced by using sparse matrices to scan the passive matrix LCDs.
