Produz uma visualização mais brilhante e nítida com um ângulo de visão mais alargado do que um monitor de matrizes passivo. Também conhecido por TFT (transístor de película fina).

Silicone amorfo (a-Si)

Um material de semicondutor utilizado para produzir a camada de transístores de película fina (TFTs) de um LCD de matriz activa.

Relação altura/largura (Aspect ratio)

A relação entre a largura e a altura de uma área activa do monitor. Em geral, a maior parte dos monitores apresenta uma relação altura/largura de 4:3. Os monitores ou TVs largos têm uma relação altura/largura de 16:9 ou 16:10.
