Sihlala siva amagama athi "4K" kwaye "ohlelo" kubomi bethu bemihla ngemihla, ngakumbi xa bekhangela amaqonga athile okuthenga kwi-Intanethi. Uninzi lweentengiso zababekidiweyo okanye ii-tvs zihlala zikhankanya ezi meko zimbini, eziqondakalayo kwaye zididekile. Emva koko, masithathe inkangeleko enkulu.
Yintoni ekhutshiwe?
I-oad inokuthathwa njengendibaniselwano yetekhnoloji ye-LCD ne-Led. Idibanisa uyilo lwe-LCD kunye neempawu ze-LUMIROOD ezikhokelayo, ngelixa zisezantsi. Isakhiwo saso siyafana ne-LCD, kodwa ngokungafani netekhnoloji ye-LCD kunye ne-LED, ongoka unokusebenza ngokuzimeleyo okanye njengesibane se-LCD. Ke ngoko, oswelekileyo isetyenziswa ngokubanzi kwizixhobo ezincinci neziphakathi ezifana neefowuni, iitafile kunye neTV.
Yintoni i-4k?
Kwicandelo leTekhnoloji yokubonisa, kuyakholelwa ngokubanzi ukuba izixhobo zokubonisa ezinokufikelela kuma-3840 × 2160 iipikseli zingabizwa ngokuba yi-4k. Olu phawu lusemgangathweni lunokubonisa umfanekiso ongaphezulu nocacileyo. Okwangoku, amaqonga amaninzi kwi-Intanethi abonelela ngeendlela ze-4K ezisemgangathweni, ukuvumela abasebenzisi ukuba banandiphe amava aphezulu evidiyo.
Umahluko phakathi kwe-od kunye ne-4K
Emva kokuqonda iitekhnoloji ezimbini, ezivulekileyo kwaye ezi-4K, zinomdla wokuthelekisa. Ke yintoni umahluko phakathi kwezi zimbini?
Ngapha koko, i-4K kunye ne-oad ziikhonsepthi ezimbini: I-4K ibhekisa kwisigqibo sekrisce, ngelixa ifakwe yitekhnoloji yokubonisa. Banokubakho ngokuzimeleyo okanye ngokudibeneyo. Ke ngoko, kubalulekile ukuqonda ukuba ziphi na ezimbini.
Ngamafutshane, okoko isixhobo somboniso sinesisombululo se-4K kwaye sisebenzisa itekhnoloji eyodwa, singayibiza ngokuba yi "4k oled".
Ngokwenyani, ezo zixhobo zihlala zibiza kakhulu. Abathengi, kubaluleke kakhulu ukuqwalasela umyinge wokusebenza kwamaxabiso. Endaweni yokukhetha imveliso ebizayo, kungcono ukukhetha isixhobo esisebenzayo. Kwimali efanayo, unokunandipha amava asondeleyo ngelixa uphuma uhlahlo-lwabiwo mali lokunandipha ubomi, njengokubukele imovie okanye ukuba nesidlo esihle. Oku kunokuba nomtsalane ngakumbi.
Ke, ukusuka kwimbono yam, kucetyiswa ukuba abathengi baqwalasele i-4K ababeka i-4K ababeka i-4k endaweni ye-4K ye-ofisi ye-ofisi ekhutshiwe. Siyintoni isizathu?
Ixabiso liyinto ebalulekileyo. Okwesibini, kukho imiba emibini yokuqwalaselwa: Ukwaluphala kwesikrini kunye nokukhetha ubungakanani.
Ukutshisa isikrini esiyimfuneko-kwingxaki
Ingaphezulu kweminyaka engama-20 okoko itekhnoloji ethengiweyo yaziswa okokuqala, kodwa iingxaki ezinje ngomahluko wombala kunye nokutsha-ngekheswe ngempumelelo. Kuba i-pixel nganye yesikrini esiyithandayo inokukhupha izibane ngokuzimeleyo, ukusilela okanye ukwaluphala kwamanye amaphiko kudala kukhokelela ekubonakaliseni ukutshisa okubizwa ngokuba yitshisi-esecaleni. Le ngxaki ihlala inxulumene ngokusondeleyo nenqanaba lenkqubo yokuphucula kunye nobungqola bolawulo oluphambili. Ngokwahlukileyo, imiboniso ye-LCD ayinazo iingxaki ezinjalo.
Ubungakanani bengxaki
Izinto ezithenjiweyo kunzima ukwenza, oko kuthetha ukuba zihlala zikhulu kakhulu, kungenjalo baya kujongana nexabiso lokugcina iindleko kunye nomngcipheko ongaphumeleliyo. Ke ngoko, itekhnoloji ye-OOD ekhoyo isasetyenziswa ikakhulu kwizixhobo ezincinci ezinje ngeefowuni kunye neetafile.
Ukuba ufuna ukwakha i-4K enkulu ye-TV-Screen TV ngesiboniso se-LED, olu lukhetho olulungileyo. Elona phenyazo likhulu lokwenza i-4K TVs kukutshintsha kwayo, kunye nobungakanani obahlukeneyo kunye neendlela zokufaka zinokuchithwa ngokukhululekileyo. Okwangoku, imiboniso ye-LED ihlulwe ikakhulu ibe ziindidi ezimbini: oomatshini bonke kunye neendonga ze-LED.
Xa kuthelekiswa nale tvs ehanjisiweyo ngasentla, ixabiso lezinto ezikhoyo ze-Lonke-ngaphandle-kwenye-enye inokuthi zibefikeleleke ngakumbi, kwaye ubungakanani bukhulu, kwaye kufanelekile.
Iindonga zeVidiyo ye-LEDKufuneka wakhiwe ngesandla, kwaye amanyathelo okusebenza anzima kakhulu, afaneleke abasebenzisi abaqhelene nokusebenza kwezandla. Emva kokugqiba ulwakhiwo, abasebenzisi kufuneka bakhuphele isoftware yolawulo lwe-LED ye-LED kwi-debug isikrini.
