What is the best type of LCD flat screen to buy?


This question was answered on April 1, 2003. Much of the information contained herein may have changed since posting.

There are two types of LCD screens which are passive matrix and active matrix.

A dual scan display which is sometimes referred to as a passive matrix display has a row of transistors running on the top of the screen (x-axes) as well as the left of the screen (y-axes) The amount of transistors are defined by the LCD manufacturer, for example the manufacturer may define 800 transistors along the x-axes and 600 transistors along the y-axes These transistors power the pixels that are powered in grids by the transistors Unfortunately if one of these transistors were to fail you would receive a solid black line going vertical or horizontal.

Unlike Dual Scan Active Matrix has transistors for each pixel generating their own light creating a more brighter and crisp display Because of this method method used for display the screen can also be viewed by multiple viewers Even though active matrix has a more crisp display each pixel that has a transistor will drain power more quickly

Anyways the Active matrix is better overall.
