Active Matrix is a technology used in most LCDs, such as laptops and flat-screen monitors.
It uses a matrix of thin-film transistors (TFTs) and capacitors through which it controls the images generated by the display. In this, the brightness of each pixel is controlled by modifying the electric charge of the respective capacitors.
Each pixel has a colour control by altering the charge of the individual capacitor that emits red, green, and blue (RGB) light.
The term “active-matrix” refers to the dynamic nature of capacitors in the display. A passive-matrix display has to charge its full rows of wires to alter its pixels, while an active-matrix display easily controls each pixel directly.
This result is that you get a significantly faster response time, meaning pixels can change their state very quickly.
In practical terms, an active-matrix monitor can show motion and fast-moving images very clearly or clearly compared to a passive-matrix display. At the same time, the fast switching of TFTs in it prevents the “ghosting” of the cursor from happening, which is a very common problem on passive-matrix screens.
Since active-matrix technology provides individual control above each pixel, active-matrix screens typically exhibit greater brightness and colour over the entire screen compared to passive-matrix displays.
With so many advantages of Active Matrix Technology, active-matrix screens are most commonly used in all modern computer monitors, laptop screens, and LCD televisions.
