Ngokufika kweesethiyamabonwakude, ubomi bomntu buguqukile ngokugqithiseleyo, baye bachitha ixesha elingakumbi ekhaya, kwintsapho. Kule mini, i-TV enhle, mhlawumbi, isifundo esiyinhloko ekhaya. Kuyavuya ukubona i-movie oyikhonzile, uchungechunge, iindaba okanye umdlalo wezemidlalo ekupheleni kosuku. Emva kokuba abantu bevuyiswe ngamaTV alula, ii-TV zeLCD zisetyenziswa ngokubanzi. Kodwa njani ukhetha i-LCD ye-TV efanelekileyo? Ziziphi iimpawu zobugcisa ze-TV ezilungele wena? Ungenzi njani iphutha xa uthenga? Makhe sibuke kunye.
Ngoko, wanquma ukuthenga i-LCD TV. Nazi imigaqo embalwa elula.
Ngokungathandabuzekiyo, into yokuqala ebamba umbono wethu we-TV ubukhulu bayo. Ngokuchanekileyo, udiagonal. Ngokuqinisekileyo, ngakumbi iTV, ngcono. Kodwa oku akunjalo ngaso sonke isikhathi. Umgama ukusuka kwi-TV ukuya kwindawo ohlala kuyo ngelixa ubonayo kubalulekile. Abaninzi abantu bayazi ukuba enkulu idiagonal, enkulu umgama kwi-sofa. Umgama ophezulu unamaxesha angaphezu kwama-3-4 ngaphezu kwe-TV. Oku kuya kunika induduzo.
Iparameter elandelayo kufuneka uyibeke ingqalelo kwisisombululo. Le xabiso liboniswa ngamaphikseli. I-Pixel yileyunithi yobuncinane bokubonisa umboniso weTV. Iqulethe ulwazi malunga nomboniso obomvu, obuluhlaza kunye nobuluhlaza. Uninzi lweepekseli zenza umfanekiso. Ngoko ke, isisombululo esiphezulu (iipekseli ezingaphezulu), ngcono umfanekiso othunyelwayo. Kubalulekile ukwazi ukuba ekubukeni ukuhanjiswa kwethempyutri eqhelekileyo, isisombululo esingu-800x600 siya kukwanela (kuba eRashiya imiboniso ye-TV isasazwa ngokwemigangatho). Nangona kunjalo, ukubukela iifrimu zeDVD, isisombululo kufuneka sibe kuhle kangangoko kunokwenzeka. Ubunono obuphezulu yindlela yokwenza iteknoloji yedijithali, kuye isisombululo esiphezulu ngama-pixels ka-1920x1080.
Ixesha lokuphendula leTV ngumzila wokutshintsha phakathi kwamnyama nomhlophe. Ifutshane ixesha lokuphendula, bhetele umbala wokunikezela, kunye nomfanekiso omnye awuyi kuphinda. Kungcono ukuba ixesha lokuphendula alidluli kwi-8 millisecond (ms).
Uphawu oluphambili lombala we-LCD TV lubugqwetha kwaye luhluke. Ukuqhathaniswa ngumlinganiselo woqhawulo lwezona ndawo zilula kakhulu nakumnyama kunomfanekiso, kunceda ukubonisa ubunzulu bombala. Umlinganiselo ochaseneyo ungaba ngu-600: 1, 800: 1, 1000: 1. Umgangatho ophezulu, ungcono. Ubumhlophe kubalulekile xa ubukela iTV kwiimeko ezahlukeneyo zokukhanyisa, i. ngexesha elikhanyayo nelomnyama losuku. Ukuba ukukhazimula kungenelisekile, amehlo akho aya kukhathala kakhulu, kwaye awuyi kukufumana ukuzonwabisa. Ukugqama kwe-450 cd / m2 kuthathwa njengesiqhelo. I-TV enjalo iya kuba mnandi ukubheka ukukhanya kwemini kunye nokukhanya okubonakalayo, ngexesha elifanayo njengoko ukudluliselwa kombala kuya kuhlala kulungile. Ezinye iimodeli zanamhlanje zee-TV ze-LCD zinezixhobo ezakhelwe ngaphakathi ezitshintsha ngokuzenzekelayo ukukhanya.
Mhlawumbi uqaphele ukuba ukuba ubukela i-LCD TV ngeengxube ezahlukeneyo (umzekelo, ukusuka kwicala, kwaye kungekhona isikhungo), ngoko umfanekiso uphazamiseka. Eli xabiso libizwa ngokuba yi-angle angle. Kukhululekile ukubukela iTV ngekona lokujonga ngaphaya kwee-degrees ezingama-180 (177-179), le mfuneko idibana nemifanekiso yamaninzi namhlanje. I-TV yokuqala ye-LCD yayinekona lokujonga elincinci kakhulu, kodwa inkqubela, njengoko uyaziyo, ayimi.
Ukudluliswa kwesandi kubalulekile. Uphawu oluphambili lwesandi kukuba lukhulu, kungekhona amandla, njengabantu abaninzi bacinga. Ubungakanani bunokulinganiswa kwi-decibels (dB). Ephakamileyo ubunzima, ngokugqithiseleyo isandi seTV siyadlala. Amandla, njengoko alinganiswe kwiWatts, ayichaphazela umgangatho wezandi ngokungabalulekanga. Ngokuqhelekileyo, abakhiqizi kwibhokisi leTV bhala amandla angama-watts angama-100, kodwa ngokubhekiselele kumgangatho ozwakalayo, awuqondi kakuhle ukuba yeyiphi impawu zamandla, unesimo sesithethi seTV. Ingqwalasela eninzi ihlawulwa ngokukhawuleza.
Amagama ambalwa malunga "nokuphuma" kunye "namangenelo". Ngokuqhelekileyo zifumaneka kwindawo yangemva kweTV. Zonke iimodeli zanamhlanje ziqulethe iifaki ezaneleyo zokudibanisa umdlali weDVD, ikhamera nezinye izixhobo. Ewe, ukuba iTV iphathwe nge-USB, ngoko unokujonga iifoto zakho ezizithandayo kwi-screen yesikrini okanye uphulaphule iifom ezithandayo ngokuxhuma ikhamera yakho okanye i-MP3 player.
Kwindlela yokucwangcisa kunye nombala we-TV enclose, mhlawumbi akufanelekile ukuthetha malunga, ngenxa yokuba bahluke kakhulu. Le nto sele sele yinto engumnandi.
Ngoko ke sihlolisise iimpawu ezibalulekileyo zeTV zeTV. Okukhethwa nguwe! Ukubukela okuthabisayo!
