Ngokuthuthuka okusheshayo kwezobuchwepheshe,Izindonga zevidiyo ze-LCD kancane kancane baba ukufakwa okuvamile ezindaweni ezahlukahlukene zokuhweba kanye nezindawo zomphakathi. Ukuthi ngabe yizitolo ezinkulu zezitolo, izakhiwo zehhovisi, noma ezinkundleni zemidlalo, izindonga zevidiyo ze-LCD zinikeza abantu okuhlangenwe nakho okusha ngencazelo yabo ephakeme, imibala ebonakalayo, kanye nomklamo we-bezel ongenamthungo. Ngasikhathi sinye, izindonga zevidiyo ze-LCD zibonisa nezinzuzo ezibalulekile ekuvikeleni amandla nokuvikelwa kwemvelo, kubenza abasekeli ababalulekile bentuthuko esimeme.
Okokuqala, izici zokonga amandla zezindonga ze-LCD zevidiyo ziholele ekusetshenzisweni kwazo okubanzi emkhakheni wezentengiso. Uma kuqhathaniswa nama-projekroni endabuko kanye namathelevishini amakhulu wesikrini, izindonga zevidiyo ze-LCD zinokusebenza kwamandla okuphezulu. Izindonga zevidiyo ze-LCD zisebenzisa ubuchwepheshe be-LED backlight, ezidla amandla amancane futhi zinokuphila okude ngokuqhathaniswa nobuchwepheshe be-Plasma backort yendabuko. Uhlelo lwe-baclight olusebenzayo lwe-LED luthuthukisa kakhulu ukusebenza kahle kwamandla kwezindonga zevidiyo ye-LCD futhi kunciphise ukuphuma kwamandla. Le nzuzo yokonga amandla ibonakala kakhulu ezikhungweni zemibukiso noma amakamelo engqungquthela anezindonga zevidiyo eziningi ze-LCD, okuletha imali etholakalayo yezindleko emabhizinisini nezinhlangano.
Ngaphezu kwezinzuzo ezibalulekile zokonga amandla, izindonga zevidiyo ze-LCD nazo zibambe ukubaluleka okukhulu emkhakheni wokuvikelwa kwemvelo. Okokuqala, inqubo yokukhiqiza yezindonga zevidiyo ye-LCD inobungani bemvelo. Ukukhiqizwa kwabaqaphi be-CRT bendabuko kudinga ukusetshenziswa kwenani elikhulu lezinto zokwakha, kufaka phakathi izinto eziyingozi ezifana nokuhola ne-mercury. Ngokuphambene nalokho, inqubo yokukhiqiza yezindonga zevidiyo ye-LCD ayihileli ukusetshenziswa kwalezi zinto eziyingozi, ukunciphisa ukungcoliswa kwemvelo kanye nobungozi empilweni yabasebenzi. Okwesibili, izindonga zevidiyo ze-LCD zinganciphisa nokungcoliswa kwemvelo ngesikhathi sokusebenzisa. Amadivayisi wokubonisa wendabuko afana ne-CRT Televils kanye nama-Projectors anezinkinga ngemisebe ye-electromagnetic kanye ne-ultraviolet, engaba yingozi empilweni yabantu. Izindonga zevidiyo ze-LCD zinemisebe ye-electromagnetic encane, ukunciphisa kakhulu ukulimala komzimba womuntu. Ngokwengeziwe, izindonga zevidiyo ze-LCD zinamakhono obufakazi bothuli kanye nobufakazi bobufakazi, okubavumela ukuba basebenze ngokujwayelekile ezindaweni ezahlukahlukene ezinokhahlo.
Ukusimama kwezindonga zevidiyo ye-LCD nakho kuboniswa kwisikhathi sabo eside isikhathi eside. Ngokusebenzisa izinto ezisezingeni eliphakeme nobuchwepheshe obuthuthukisiwe, izindonga zevidiyo ze-LCD zinokuphila okude kakhulu ngokuqhathaniswa namadivayisi wokubonisa wendabuko. Ngokuvamile, isikhathi sokuphila esijwayelekile sezindonga zevidiyo ye-LCD singadlula iminyaka emi-5, nasezindaweni ezithengiswayo eziphezulu, isikhathi sokuphila singafinyelela eminyakeni engaphezu kwemithathu. Ngaleso sikhathi, izindonga zevidiyo ze-LCD zisebenza kakhulu, zivumela ukulungiswa okujwayelekile kanye nokuxhaswa ukuze kunwetshwe isikhathi sazo sokuphila. Lokhu kusho ukuthi amabhizinisi nezinhlangano azidingi kaningi ukufaka esikhundleni semishini, ukunciphisa imfucuza yezinsiza kanye nesizukulwane sedoti kagesi, ukuthuthukisa kakhulu ukuqina kwamadivayisi.
Ekuphetheni, izindonga zevidiyo ze-LCD seziphenduke ukukhetha okuhle emkhakheni wezohwebo kanye nezindawo zomphakathi ngenxa yezici zazo zokonga amandla, ezinobungane nezemvelo nezinde. Uma kuqhathaniswa namadivayisi wokubonisa wendabuko, izindonga zevidiyo ze-LCD zinokusebenza kahle kwamandla okuphezulu, ukungcoliswa okuphansi kwezemvelo, kanye nokuphila okude. Ukutshala imali ezindongeni zevidiyo ye-LCD akugcini nje ngokuletha ubuchwepheshe obuthuthukisiwe kanye nemiphumela emihle yokubuka kumabhizinisi nezinhlangano kodwa futhi inikela ekuthuthukisweni okuqhubekayo futhi yenza umnikelo ekuvikelweni okuluhlaza okwesikhashana.
