The Active matrix screen is composed of thousands of LCDs with a small transistor attached behind them. When the video adapter gives the instruction to light a particular pixel, the transistor sends electricity through two electrodes, which "light the LCD". There is a few ups and downs surrounding the active matrix technology. The upside to the story is that the picture produced is very clear and easy to see. On the downside, the active matrix design uses an immense amount of power. Therefore shortening the time available for batter powered laptop.
