Yikuphi Ukuqapha Okungcono Kokuthenga?
Kuleli qophelo nesikhathi, abaqaphi be-CRT basubuchwepheshe obungaphelelwe yisikhathi. Ngokuyinhloko konke ukukhiqizwa kwama-cathode ray amashubhu kuye kwaqedwa ngenxa yezindleko nokukhathazeka kwemvelo. Ngenxa yalokhu, cishe ngeke ukwazi ukuthola ukubonisa okunjalo. Esikhundleni salokho, zonke izibonisi zekhompyutha ziyi- LCD ngenxa yokuthuthukiswa kobuchwepheshe obenza kube ngcono kumbala, ukubuka ama-angles ngisho nokubonisa ngaphandle kwesinqumo sabo semvelo.
Izinhlelo eziningi zekhompyutha zekhompuyutha ezithengiswa manje ngokuzenzakalelayo ziza nabahloli be-LCD. Noma kunjalo yilokho okumele ukwazi ukuthi umehluko nokuthi kuzoba ngcono ekuthengeni, sibuyekeze lesi sihloko ukuze sihambisane nobuchwepheshe bamanje kanye nemikhiqizo enikeziwe namhlanje.
I-CRTs
Inzuzo eyinhloko ukuthi abahloli be-CRT abanjwe phezu kwama-LCD kwakunikeza umbala wabo. Ukulinganisa nokugqama kwemibala ebonisiwe kwakukhulu kakhulu nabahloli be-CRT kunama-LCD. Nakuba lokhu kusenjalo ezimweni eziningi, ukuqhuma okuningi kwenziwe ekwenzeni i-LCD njengokuthi lo mmahluko awunjalo njengoba wawunjalo ngaphambili. Abakhiqizi abaningi bezithombe abasebenzisa izibukeli ezinkulu ze CRT emsebenzini wabo ngenxa yezinzuzo zombala. Yiqiniso, lekhono lemibala lihlaziya ngokuhamba kwesikhathi njengoba i-phosphors ebhukwini ihlehla.
Enye inzuzo ukuthi abahloli be-CRT abanjwe phezu kwezikrini ze-LCD yikhono lokufinyelela kalula ezinqumweni ezihlukahlukene. Lokhu kubizwa ngokuthi yi-multisync yemboni. Ngokulungisa i-electron beam in tube, isibuko singashintshwa kalula kuya ezinqumweni eziphansi ngenkathi kugcinwe ukucaca kwesithombe.
Nakuba lezi zinto ezimbili zingadlala indima ebalulekile kubahloli be-CRT, kunezimo ezifanayo. Okukhulu kunazo zonke kukhona ubukhulu nesisindo samatayipi. Umshini wokulinganisa i-LCD olinganiselwe uphansi kwama-80% amancane ngesayizi nesisindo uma kuqhathaniswa nethubhu ye-CRT. Ikhudlwana isikrini, i-bigger ubukhulu besayizi. Esinye isici esiyinhloko sisebenza ngokusetshenziswa kwamandla. Amandla adingekayo ekwenzeni i-electron beam isho ukuthi uhlolisisa umthengi futhi akhiqize ukushisa okukhulu kunabakhokeli be-LCD.
Izinzuzo
- I-Multisync inamandla
- Amazinga Aphezulu Wokuvuselela
- Faka umbala ocacile nokujula
I-Cons
- Kunzima kakhulu futhi kunkulu
- Sebenzisa Amanani Amakhulu Amandla
- Yenza Ukushisa Okudlulele
Ama-LCD
Inzuzo enkulu kubaqapheli be-LCD yisayizi nesisindo sabo. Njengoba kushiwo ngaphambili, ubukhulu nesisindo somqapha we-LCD kungaba ngaphezu kwe-80% elula kunesikrini esifanayo se-CRT. Lokhu kwenza ukuba abasebenzisi babe nezikrini ezinkulu kumakhompyutha abo kunakwenzeka ngaphambili.
Izikrini ze-LCD nazo zivame ukhiqiza ukukhathala kancane komsebenzisi. I-constant barrage kanye nemigqa yokuskena yesikhumbi se-CRT ivame ukubangela ukucindezeleka kubasebenzisi abakhulu bekhompyutha. Ubukhulu obuncane bokubukwa kwe-LCD kanye nokuboniswa kwabo kwesikrini njalo kwamaphikseli njengoba kuvuliwe noma kuvaliwe kuveza ukukhathala okuncane komsebenzisi. Kumele kuqashelwe ukuthi abanye abantu basenenkinga ngokukhanyisa kwe-fluorescent asetshenziswe kwezinye izinkinobho ze-LCD. Lokhu kukwenziwe ukusetshenziswa okuqhubekayo kwama-LED kunokuba kube nezibhubhu ze-fluorescent.
Ukungahleleki okuphawulekayo kwizikrini ze-LCD yisinqumo sabo esinqunyiwe noma sokuzalwa . Isikrini se-LCD singabonisa kuphela inani lamaphikseli ku-matrix yalo futhi akusekho noma ngaphansi. Kungabonisa isinqumo esincane ngezindlela ezimbili. Ukusebenzisa kuphela ingxenyana yamaphikseli aphelele esibonisweni noma ngokusebenzisa i-extrapolation. I-extrapolation yindlela lapho umqaphi uhlanganisa khona amaphikseli amaningi ndawonye ukuze alingise i-pixel encane eyodwa. Lokhu kungase kuholele esithombeni esicacile noma esingenangqondo ikakhulukazi ngombhalo uma usebenzisa isikrini ngezansi isinqumo sendawo. Lokhu kuye kwathuthuka kakhulu ngaphezu kweminyaka ukuthi akuyona inkinga enkulu.
Le vidiyo yayinenkinga ngezingqapheli zangaphambili ze-LCD ngenxa yezikhathi zokuphendula kancane. Lokhu kunqotshwa ukuthuthukiswa okuningi, kodwa kunezinye ezisezikhathi zokuphendula eziphansi. Abathengi kufanele bazi lokhu uma bethengisa umqapha. Kodwa-ke, ukuthuthukiswa kuvamise ukusebenza okungaholela empeleni kwenye inkinga yokucaciswa kombala okunciphise. Ngeshwa, imboni impofu kakhulu ngokuhlunga ngokucacile lokho okushiwo abaqaphi ukuze basize abathengi baqonde futhi baqhathanise abaqaphi.
Izinzuzo
- Okuncane futhi Okumhlophe
- I-Energy Efficient
- Kubangelwa Ukukhathala Kwamehlo Okuncane
I-Cons
- Blurry Izithombe Ngaphandle Isinqumo IsAmbulo
- I-Blur Motion ku-Izithombe Ezinyakazayo Ezihambayo
- Amanye amamodeli aye anciphisa umbala ocacile
