Malo oyipa a skrini ya LCD amatchedwanso kusapezekapo.Zimatanthawuza ma pixel ang'onoang'ono omwe amawonetsedwa pazenera za LCD zakuda ndi zoyera ndi zofiira, zobiriwira ndi zabuluu.Mfundo iliyonse imanena za sub-pixel.Chojambula chowopsa kwambiri cha LCD ndi mfundo yakufa.Pixel yakufa ikachitika, mfundo yomwe ili pachiwonetsero nthawi zonse imawonetsa mtundu womwewo mosasamala kanthu za chithunzi chomwe chikuwonetsedwa."Nthawi yoyipa" iyi ndi yosatheka ndipo itha kuthetsedwa posintha mawonekedwe onse.Mfundo zoipa zikhoza kugawidwa m'magulu awiri.Mfundo zamdima ndi zoipa ndi "madontho akuda" omwe sangathe kusonyeza zomwe zilimo mosasamala kanthu za kusintha kwa mawonekedwe owonetsera, ndipo chinthu chokhumudwitsa kwambiri ndi mtundu wa mawanga owala omwe amakhalapo nthawi zonse pambuyo powombera.Ngati vuto laukadaulo limayambitsidwa ndi ma pixel akufa akadali osasinthika.Komabe, ngati ndi chifukwa cha ma pixel akufa omwe amasiyidwa pachithunzichi kwa nthawi yayitali, akhoza kuchotsedwa ndi kukonza mapulogalamu kapena kupukuta.
Pixel yakufa ndikuwonongeka kwakuthupi komwe sikungapeweke popanga ndikugwiritsa ntchito zowonera zamadzimadzi zamadzimadzi.Nthawi zambiri, zimachitika pamene chophimba amapangidwa.Kuwonongeka kwachilengedwe pakagwiritsidwe ntchito kungayambitsenso mawanga owala / oyipa.Malingana ngati mtundu umodzi kapena yambiri mwa mitundu itatu yoyambirira yomwe imapanga pixel imodzi yawonongeka, mfundo zowala / zoipa zimapangidwa, ndipo kupanga ndi kugwiritsa ntchito kungayambitse kuwonongeka.
Komabe, zowonetsera zina za LCD zili ndi mfundo yoyipa pakugwiritsa ntchito.M'munsimuTopfoisonamangotchula malo ena oyenera kusamala mukamagwiritsa ntchito nthawi zonse:
1. Sungani mphamvu yamagetsi yabwinobwino;
2, chophimba cha LCD ndi chimodzi mwazinthu zomwe zili pachiwopsezo kwambiri, ndibwino kuti musagwiritse ntchito zolembera, makiyi ndi zinthu zina zakuthwa kuti muloze pazenera;
3, kuchepetsa mwayi wowonekera pachindunji powala kwambiri, pofuna kupewa kuti chinsalucho chisawonekere ndi kuwala kwamphamvu, zomwe zimapangitsa kutentha kwambiri komanso kukalamba mwachangu.
4, pamene ntchito, ayenera kupewa nthawi yaitali jombo ntchito, koma sangathe kusonyeza chophimba chomwecho kwa nthawi yaitali, kotero n'zosavuta imathandizira ukalamba LCD chophimba, ndi kulimbikitsa mapangidwe mapikiselo akufa.
Zomwe zili pamwambazi ndi njira zochepa chabe poyang'ana gulu la LCD.Pali njira zambiri zodziwira mapanelo a LCD.Tili ndi njira yatsopano komanso yabwinoko yokuuzirani koyamba.
