A type of video display (originally for notebooks or laptops) where each picture element (pixel) is represented by a single transistor. In contrast, a passive-matrix display uses a series of criss-crossed wires with an LCD element at each intersection, and each LCD element represents a pixel. Active-matix displays produce the sharper image and are more expensive to produce.
The technology using a large array of liquid crystal cells for computer displays.
It is a type of flat-panel display in which the screen is refreshed more frequently than in conventional passive-matrix displays. The most common type of active-matrix display is based on a technology called THT (thin film transistor). The two terms, active-matrix and TFT, are equivalent and are often used for one another.
