Glossary definition of Passive matrix

Passive matrix is the cheapest type of LCD display. It consists of a basicliquid crystaldisplay with pixels divided into a matrix of rows and columns; only one row and one column receive electric current at any one time. This leads to a low contrast, slow response time and a narrow viewing angle, although it does have the benefit of having very low power consumption.

Passive matrix also suffers from crosstalk where voltage for a particular row and column can leak through to nearby pixels, causing a ghosting effect. This makes passive matrix unsuitable for animation and moving video, although it is stillgood with static images.

Active matrix LCDs alleviate some of the issues that passive matrix suffers from.
