Yiyiphi iNgcaciso engcono kakhulu yokuthenga?
Ngeli xesha kunye nexesha, abahloli be-CRT esekelwe ubugcisa bexesha elidlulileyo. Okubaluleke kakhulu ukuba yonke imveliso yezibatho ze-cathode ray iyanqanyiswa ngenxa yeendleko kunye nokukhathazeka kwemeko. Ngenxa yoko, mhlawumbi akunakukwazi ukufumana umboniso onjalo ukuthengiswa. Kunoko, zonke iimboniselo zekhomputha ziyi- LCD ngenxa yokuphucula ubugcisa obwenza ukuba kube ngcono kumbala, ukujonga iilwimi kunye nokubonisa ngaphandle kwesisombululo sabo.
Iinkqubo ezininzi zekhompyutheni ezithengiswa ngoku ngokuzenzekelayo ziza kunye nabahloli beLCD. Nangona kunjalo ukuba oko kukwazi ukumahluko kunye nokuba babeya kuba ngcono xa kuthengwa, siye sahlaziya le nqaku ukuba ifaneleke ngakumbi kwezobuchwepheshe kunye nemveliso ekhoyo namhlanje.
CRTs
Inzuzo ephambili ukuba abagadi be-CRT abanjwe kwi-LCD babenomboniso wabo wokubala. Ukungafani nokuhla kwemibala ebonisiwe kwakukhulu kakhulu nabagadi be-CRT kuneLCD. Nangona le nto iqhubekile kwiimeko ezininzi, amaninzi amaninzi ayenziwe kwiiLCD ezifana nokuba lo mmahluko awunjalo njengoko wawunjalo ngaphambili. Abaninzi abayizicatshulwa beemifanekiso basasebenzisa iindleko ezinkulu ze-CRT emsebenzini wabo ngenxa yemigangatho yebala. Ngokuqinisekileyo, lo mbala ukwazi ukuhlaziya ixesha elide njengoko i-phosphors kwi-tube iyaphula.
Enye inzuzo yokuba abagadi be-CRT abanjwe kwizikrini ze-LCD banako ukukhawuleza kwizigaba ezahlukahlukeneyo. Oku kuthethwa njenge-multisync yoshishino. Ngokulungelelanisa intambo ye-electron kwiphubhu, isikrini sinokulungiswa ngokukhawuleza ukuya kwisigqibo esincinci ngelixa kugcinwe ukucaca komfanekiso.
Nangona ezi zinto zibini zingadlala indima ebalulekileyo kwizibonisi ze-CRT, kukho ukungalunganga. Okukhulu kunabo kwezi zibukhulu kunye nobukhulu beethubhu. I-monitor ye-LCD enokulingana ifana ne-80% encinci ngobukhulu kunye nobunzima xa kuthelekiswa nethubhu ye-CRT. Ikhudlwana kwesikrini, inkulu kakhulu umahluko wobukhulu. Enye enye ingxaki ejongene nokusetyenziswa kwamandla. Amandla adingekayo kwiibhola ze-electron kuthetha ukuba abagadi bamagcini kunye nokuvelisa ukushisa okuninzi kunabameli be-LCD.

LCD
Inzuzo enkulu kunazo zonke kubabukeli be-LCD bubungakanani nobukhulu babo. Njengoko kukhankanywe ngaphambili, ubukhulu kunye nobukhulu benkqubo yokujonga i-LCD ingaba ngaphezu kwama-80% ukukhanya ngaphezu kwesicatshulwa esifanayo se-CRT. Oku kwenza ukuba abasebenzisi babe nezikrini ezinkulu kwiikhomputha zabo kunokuba kunokwenzeka ngaphambili.
Izikrini ze-LCD nazo zivame ukuvelisa ukukhathala kwesohlo kumsebenzisi. Imizila yokukhanya yokukhanya kunye neendlela zokukhangela zeTTT zivame ukubangela ubunzima kubasebenzisi abasebenzisa iikhomputha. Ubunzulu obuncinane bee-LCD abajongene kunye nokubonakaliswa kwabo kwesikrini rhoqo kweepikseli ezikhoyo okanye ezivaliweyo zivelisa ukhathala okungaphantsi komsebenzisi. Kufuneka kuqatshelwe ukuba abanye abantu basenemiba kunye nokukhanyisa kwe-fluorescent esetyenziswa kwezinye iindawo ezikhanyayo ze-LCD. Oku kuye kwacinywa ngokusetyenziswa kwee-LED kunokunyuka kwama-tubs flurescent.
Iyona nto iphawulekayo kwiingcingo ze-LCD yisisombululo esisigxina okanye sokuzalwa . Iskrini seLCD sinokubonisa kuphela inani leepekseli kwi-matrix yayo kwaye akukho ngaphantsi okanye ngaphantsi. Ingabonisa isisombululo esezantsi kwisinye seendlela ezimbini. Ukusebenzisa kuphela isahlulo seepikseli ezipheleleyo kwisiboniso okanye nge-extrapolation. I-extrapolation yindlela apho umboniso udibanisa amaphikseli amaninzi ukulinganisa i-pixel encinane. Oku kunokukhokelela kumfanekiso ogqamile okanye ongenangqiqo ngokukodwa ngokubhaliweyo xa usebenzisa isikrini esingezantsi sisisombululo sendawo. Oku kuye kwaphucula kakhulu kwiminyaka yokuba ayikho enye ingxaki.
Le vidiyo yayinengxaki kunye nabaqapheli bokuqala beLCD ngenxa yexesha lokuphendula ngokukhawuleza. Oku kunqotshwa yimpumelelo emininzi, kodwa kukho ezinye ezisezihlandlo zokuphendula eziphantsi. Abathengi kufuneka baqaphele oku xa bethenga umlindi. Nangona kunjalo, uphuculo luhlala lusebenza ngokubangela ukuba kukho enye ingxaki yokuchaneka kombala. Ngelishwa, le shishini lihle kakhulu kakhulu ngokubeka uluhlu olufanelekileyo kwiinkcukacha zezilindisi ukubanceda abathengi baqonde kwaye baqhathanise nabahloli.
