Kungekudala, ii-kinescope zeTV ziphantse zaphela ekugqibeleni - azifumaneki kwiivenkile zecomputer, ngaphandle kwamanye amakhaya. Kodwa i-TV emancinci, emincinci ayifumanwanga njengento yokunethezeka kuwo onke kwaye isetyenziselwa yonke indawo, kwaye imizekelo emitsha enezobuchwepheshe eziphambili ziveliswa minyaka yonke. Ngako oko, abathengi abanokuthi bafumana kunzima ukugqiba ukhetho lokugqibela lwe "bluhlaza bluhlaza" phakathi kobuninzi bezinto ezicetywayo. Siza kukuxelela nge- TV ye-TV kunye neenzuzo zayo.
Yintoni iteknoloji ye-LED?
Ngokuqhelekileyo i-LED yisigcawu ngesiNgesi, esimele "i-diode ekhanyayo". Ibinzana liguqulelwa kwisiRashiya nje-LED. Kwaye xa sithetha malunga noko kuthetha ukuthini i-TV ye-TV, ngoko ngokwenene inokuthiwa yi-LCD ephezulu yeTV.
Kuyaziwa ukuba uLC iteknoloji esekelwe ekusebenziseni i-crystal matrix yamanzi. Eli lilandelayo linamacwecwe amabini, phakathi kokufakwa kwamakristal. Xa kusetyenziswa umbane wamandla, baqala ukuhamba. Kodwa ngokubonga izibani zokukhanyisa kumhlaba we-matrix zibonakala zibe mnyama kwaye zibala. Kwaye kunye nezihlunu zombala, ezifumaneka emva komthamo, yenza umfanekiso wombala kwisikrini.
Ngokubhekiselele kuluphi uhlobo olukhanyayo lwe-LED, ke inani elikhulu lama-LED lisetyenziswe njengomthombo wokukhanya (ngokungafani ne-LCD backlight, apho kusetshenziselwa khona izibane zentambo epholileyo).
Ngaloo ndlela, umgaqo wokusebenza kwe-TV ye-TV isekelwe ekukhanyeni kwamakristali amanzi e-matrix ngama-LED.
Iingenelelo kunye nokungalunganga kwamaTV e-TV
I-TV kunye neTheknoloji ye-LED ineenzuzo ezininzi. Mhlawumbi, inzuzo enkulu kukusetyenziswa kombane ngokuncitshiswa: ngokweengcali, ukuya kuma-40% xa kuthelekiswa nabahloli be- LCD , apho i-backlight iyenziwa ngamabane e-fluorescent.
Ukongezelela, iliso le-LED lilungelelanisa naluphi na lwangaphakathi-ii-LED zingenza i-monitor kuze kube ngu-3-3.5 cm ubukhulu, kuba eqinisweni ii-LED zincinci. Kwaye, akusilo umda. Ngendlela, kukho ulwahlulo kumalungiselelo e-LED kwii-TV ze-LED, apho ubukhulu bomthamo buxhomekeke khona. Kwimeko xa bebekwe eceleni kwepaneli yeTV, bathi kusuka kwi-Direct LED. Siyabulela oku, ukukhanya kwesikrini kuqhutywe ngokufanayo. Ngokuqinisekileyo uvile ngeempawu zeTV zeTV. Ngokubhekiselele kulolu hlobo lokubuyiselwa kwe-LED ye-Edge, i-LED ebizwa ngokuba yi-LED ejikeleze umjikelezo wesikrini kunye nokusetyenziswa kwepaneli. Ngenxa yoko, ububanzi bepaneli bubuncinci-ngaphantsi kwe-3 cm! Ngendlela, kwiivenkile zeekhompyutri ngokuqhelekileyo ekutyunjweni komzekelo kukho i-Slim LED - yintoni na? Ukutyunjwa kweeTV kumabonakude ubuncinane ubunzima bomzimba ngu-22.3 mm. Ngokuqhelekileyo loo mizekelo ibonakala ingenaso isiqendu esaziwayo malunga nekrini, nangona ngokwenene iphantsi kweklasi yesikrini.
Inzuzo enkulu yeTV yeTV ingabizwa kwaye iphuculwe umgangatho womfanekiso. Ngokuphunyezwa kwe
I-drawback enkulu ye-TV ye-LED yindleko zayo ephezulu kumlinganiselo weethelevishini kunye nezinye iintlobo zokukhanyisa. Nangona kunjalo, kukholelwa ukuba njengoko iteknoloji iphucula, ukuveliswa kweTV kunye nokukhanyisa kwe-LED kuya kuthatha ubunzima bomzimba, kwaye ngoko ixabiso liza kuhla.
