Philips regler ved pixeldefekter

Philips' regler ved pixeldefekter på fladskærme

Philips tilstræber at levere produkter af den højeste kvalitet. Vi anvender nogle af branchens mest avancerede produktionsprocesser og udfører en streng kvalitetskontrol. En gang imellem er defekte pixler eller sub-pixler på TFT LCD-skærme dog uundgåelige. Ingen producent kan garantere, at alle paneler vil være fri for pixeldefekter, men Philips garanterer, at enhver skærm med et uacceptabelt antal defekter repareres eller udskiftes under garantien. Dette notat forklarer de forskellige former for pixeldefekter og definerer de acceptable defektniveauer for hver type. For at være berettiget til reparation eller udskiftning under garantien skal antallet af pixeldefekter på en TFT LCD- fladskærm overskride disse acceptable niveauer. For eksempel må højst 0,0004% af sub-pixlerne på en 15" XGA- skærm være defekte. Desuden sætter Philips endnu højere kvalitetsnormer for visse typer eller kombinationer af pixeldefekter, derer mere generende end andre. Denne pixelpolitik gælder i hele verden.

Pixler og sub-pixler

En pixel eller et billedelement er sammensat af tre sub-pixler med primærfarverne rød, grøn og blå. Når mange pixler sættes sammen, kan de danne et billede. Når alle sub-pixler i en pixel lyser, fremstår de farvede sub-pixler tilsammen som enkelt hvid pixel. Hvis de alle er mørke, fremstår de tre farvede sub-pixler tilsammen som en enkelt sort pixel. Andre kombinationer af oplyste og mørke sub-pixler fremstår som enkelte pixler i andre farver.

Forskellige typer pixeldefekter

Pixel- og sub-pixeldefekter optræder på skærmen på forskellige måder. Der er to kategorier af pixeldefekter og flere typer sub-pixeldefekter i hver kategori.

Bright Dot Defects (Defekte lyse prikker) Defekte lyse prikker fremkommer som pixels eller underpixels, der altid lyser eller er "på". Det vil sige, at en lys prik er en underpixel, der fremstår på skærmbilledet, når skærmen viser et mørkt mønster. Der er følgende typer defekte lyse prikker:
