AMLCDs are a relatively mature technology, and desirable in the above applications due in part to their low weight, flexibility, thinness, luminous efficacy, pixel density, image quality, range of possible color gamuts, and quick response times.
Because an AMLCD requires a backlight, one typically cannot display true black — instead, dark gray is shown.
The utilization of LED backlighting enables some AMLCDs (mostly televisions) to employ methods like localized dimming to increase their perceived contrast ratio.
[1] The first functional AMLCD with thin-film transistors was made by T. Peter Brody, Fang-Chen Luo and their team at Westinghouse Electric Corporation in 1972.
[4] The most common type of AMLCD contains, besides the polarizing sheets and cells of liquid crystal, a matrix of thin-film transistors to make a thin-film-transistor liquid-crystal display.
