1.   By comparison, dual scan displays are not as bright, and tend to deteriorate when viewed at an angle.

2.   By comparison, a dual scan display uses just a couple of thousand transistors that send signals through wires behind the screen.

3.   In addition to providing a clearer picture, active matrix can handle more colors and higher resolution than dual scan.

4.   Is it worth spending more for an active matrix display, or is dual scan good enough.
