Lyse eller mørke billedpunkter
Efter produktionsteknikkens aktuelle standard kan et absolut fejlfrit skærmbillede ikke garanteres.
Der kan forekomme nogle få konstant lyse eller mørke billedpunkter. Det maksimalt tilladte antal af
disse billedpunker fastlæges af den strikse internationale ISO 13406-2 (klasse II).
Eksempel: En 17"/19" fladskærm med opløsningen 1024 x 1280 har 1024 x 1280 = 1310720 pixels.
Hver pixel består af tre subpixels (rød, grøn og blå), således at der er ca. 4 millioner subpixels. I
henhold til ISO 13406-2 (klasse II) må maks. 6 pixels og tillige 7 subpixels være defekte, dvs. i alt
25 defekte subpixels.
En 22" wide-fladskærm med opløsningen 680 x 1050 har 1680 x 1050 = 1764000 pixels. Hver pixel
består af tre subpixels (rød, grøn og blå), således at der er ca. 5 millioner subpixels. I henhold til
ISO 13406-2 (klasse II) må maks. 8 pixels og tillige 10 subpixels være defekte.
