active matrix

The type of technology used in all LCD-based, flat panel color displays including TVs and desktop and laptop screens. It produces a brighter and sharper display with a broader viewing angle than passive matrix LCD screens, which are mostly monochrome. Active matrix technology uses a thin film transistor at each pixel and is often designated as a "TFT screen." See passive matrix and LCD.
