Co je to AMOLED displej?
AMOLED ( active-matrix organic light-emitting diode ) je zobrazovací technologie pro použití v mobilních zařízeních a televizích. OLED je technologie velmi tenkých displejů, kde organické sloučeniny vytváří elektroluminiscenční materiál a aktivní matice umožňuje přesné adresování jednotlivých pixelů (bodů obrázku).
Od roku 2012, je AMOLED technologie používána v mobilních telefonech , multimediálních přehrávačích a digitálních fotoaparátech, což umožňuje nízkou spotřebu těchto zařízení a zvětšení velikosti displeje (např. až 40 palců).

AMOLED displej se skládá z aktivní matice OLED pixelů, které vytvářejí světlo při elektrické aktivaci a jsou uloženy do Thin Film Transistor (TFT) pole, které slouží, jako řada přepínačů pro ovládání proudu pro každý jednotlivý pixel a tím se dosáhne požadované barvy bodu a snížení spotřeby produ pro pasivní provoz matice OLED.

V TFT sběrnici se používá polykrystalický a amorfní křemík což umožňuje dosáhnout pružnosti a ohebnosti AMOLED displeje.
