14.2. Pixelfouten bij lcd-tv's
Ondanks het gebruik van de mo-
dernste productiemethoden kun-
nen vanwege de zeer complexe
techniek in zeldzame gevallen en-
kele of meerdere pixels uitvallen.
Bij actieve-matrix TFT-schermen
met een resolutie van 1920 x 1080
pixels, die zijn samengesteld uit elk
drie subpixels (rood, groen, blauw),
worden in totaal ca. 6,2 miljoen
aansturingselementen gebruikt.
Door dit zeer grote aantal transisto-
ren en het daarmee gepaard gaan-
de, uiterst complexe productiepro-
ces kan er sporadisch sprake zijn van uitvallende of verkeerd aangestuurde pixels of
afzonderlijke subpixels.
