There are two main types of LCDs used in computers:

passive matrix and active matrix.

Most LCD displays use active matrix technology. A thin

film transistor (TFT)arranges tiny transistors and capacitors

in a matrix on the glass of the display. To address a

particular pixel, the proper row is switched on , and then a

charge is sent down the correct column. Since all of the

other rows that the column intersects are turned off, only

the capacitor at the designated pixel receives a charge. The

capacitor is able to hold the charge until the next refresh

cycle.
