What is Passive Matrix LCD?

This is the older type of LCD, and is still used in smaller displays. Here, the liquid crystals making up the display are addressed by their row and column number, and each row and column has a single controlling circuit. This form of addressing doesn’t allow fast responses, and this is most noticeable in large screens, where it manifests as the ghosting effect.

After Active Matrix LCDs were invented, this technology began to be referred to as Passive Matrix.
