1. Ikhwalithi yokubonisa ephezulu
Njengoba iphoyinti ngalinye lesibonisi sekristalu ewuketshezi ligcina umbala nokukhanya ngemva kokuthola isignali, likhipha ukukhanya okungashintshi, ngokungafani ne-cathode ray tube display (CRT), edinga ukuvuselela njalo izindawo ezikhanyayo.Ngenxa yalokho, isibonisi se-LCD singokwekhwalithi ephezulu futhi asicwayizi neze, sigcina ukucindezelwa kwamehlo kuncane.
2. Inani elincane lemisebe kagesi
Dawuniloda umbhalo ogcwele Izinto ezibonisiwe zokuboniswa kwendabuko yimpushana ye-phosphor, eboniswa yi-electron beam eshaya impushana ye-phosphor, futhi lapho i-electron beam ishaya khona impushana ye-phosphor.
Kuyoba khona imisebe ye-electromagnetic enamandla phakathi naleso sikhathi, nakuba imikhiqizo eminingi yokubonisa iye yenza ukwelashwa okuphumelelayo enkingeni yemisebe, futhi izama ukunciphisa inani lemisebe, kodwa kunzima ukuyiqeda ngokuphelele.Uma kuqhathaniswa, imibukiso yekristalu ewuketshezi inezinzuzo zemvelo ekuvimbeleni imisebe, ngoba ayikho nhlobo imisebe.Mayelana nokuvimbela igagasi logesi, isibonisi sekristalu ewuketshezi siphinde sibe nezinzuzo zayo ezihlukile.Isebenzisa ubuchwepheshe obuqinile bokuvala uphawu ukuze ivale inani elincane lamagagasi kagesi asuka kumjikelezo wokushayela esibonisini.Ukuze kuqedwe ukushisa, isibonisi esijwayelekile kufanele senze isifunda sangaphakathi sibe ngangokunokwenzeka.Lapho uthintana nomoya, amaza kagesi akhiqizwe isekethe yangaphakathi azovuza ngenani elikhulu.
3. Indawo enkulu yokubuka
Ngombukiso wosayizi ofanayo, indawo yokubuka yesibonisi se-liquid crystal inkulu.Indawo yokubuka yemonitha ye-LCD iyafana nosayizi wayo we-diagonal.Ngakolunye uhlangothi, imibukiso yeshubhu ye-cathode ray inomngcele oyi-intshi noma ngaphezulu eduze kwephaneli yangaphambili yeshubhu lesithombe futhi ayikwazi ukusetshenziselwa ukuboniswa.
4. Usayizi omncane nesisindo esincane
Izibonisi zethubhu ye-cathode ray yendabuko zihlala zineshubhu le-ray elikhulu eligcwele ngemuva kwazo.Abaqaphi be-LCD baphula lo mkhawulo futhi banikeze umuzwa omusha ngokuphelele.Abaqaphi abavamile bakhipha imishayo ye-electron esikrinini ngesibhamu se-electron, ngakho-ke intamo yeshubhu yesithombe ayikwazi ukwenziwa ibe mfushane kakhulu, futhi umthamo wawo wonke umshini wokuqapha uzokwenyuka nakanjani lapho isikrini senyuka.I-liquid crystal display ifinyelela injongo yokubonisa ngokulawula isimo sama-molecule ekristalu ewuketshezi ngama-electrode akusikrini sokubonisa.Ngisho noma isikrini sikhulisiwe, ivolumu yaso ngeke inyuke ngokulinganayo, futhi ilula kakhulu ngesisindo kunesibonisi esivamile esinendawo yokubonisa efanayo.
