Der begriff aktiv matrix display oder amlcd kurz fur engl active matrix liquid crystal display wird hauptsachlich fur flussigkristallbildschirme verwendet die eine matrix von dunnschichttransistoren enthalten mit denen lcd bildpunkte angesteuert werden jeder einzelne bildpunkt besitzt eine schaltung mit aktiven komponenten meist transistoren und stromversorgungsanschlusse. An active matrix liquid crystal display is a type of flat panel display the only viable technology for high resolution tvs computer monitors notebook computers tablet computers and smartphones with an lcd screen due to low weight very good image quality wide color gamut and response time the concept of active matrix lcds was proposed by bernard j lechner at the rca laboratories in 1968 the first functional amlcd with thin film transistors was made by t peter brody fang . The active matrix liquid crystal display amlcd is a flat panel display in which the display medium is liquid crystal and each picture element pixel is driven by such active devices as diodes or transistors these active devices are arranged in rows and columns on a glass substrate to control each pixel and hence the name of active matrix. The active matrix liquid crystal display amlcd is now the display of choice for most applications and dominates the current market the most important technology is the amorphous silicon thin film transistor based display liquid crystal technology has enabled both passive and active types the passive display has the advantages of ease of fabrication and low cost but suffers in performance active matrix electronics resolve the scanning limitations of these and the cross talk . Active matrix liquid crystal displays amlcds are the preferred choice when thin low power high quality and lightweight flat panel displays are required here is the definitive guide to the theory and applications of amlcds contemporary portable communication and computing devices need high image quality light weight thin and low power flat
