Active-matrix display
Alternatively referred to as Thin Film Transistor (TFT) and Active-matrix LCD (AMLCD), an active-matrix display is a liquid crystal display (LCD) first introduced with the IBM ThinkPad in 1992. With active-matrix displays, each pixel is controlled by one to four transistors that can make the screen faster, brighter, more colorful than passive-matrix, and capable of being viewed at different angles. Because of this improved technology, active-matrix screens are often more expensive but better quality than a passive matrix display.
While active-matrix displays do have a crisp display because each pixel has its own transistor, you will find that when running off a battery that the power drains faster. Also, because of the number of transistors, there is more of an opportunity for dead pixels.
In conclusion, the active-matrix may have disadvantages like any technology. However, is still recommended by most over the dual-scan technology.
