Xa uthengaTV, sihlala sibhideka ngamagama anje “ngesisombululo se-4K” kunye “nesantya esiphezulu sokuhlaziya,” kodwa bambalwa abantu abaqaphelayo ukuba “iqhawe elingadunyiswanga” elimisela umgangatho womfanekiso ngokwenene “isisombululo se-optical” Ngamafutshane, isisombululo se-optical yiseti yeendlela ezisetyenziswa yiTV “ukuphatha ukukhanya”: indlela yokwenza ukukhanya kube yimifanekiso ngokuchanekileyo, indlela yokuvelisa imibala ngendlela engokoqobo, indlela yokuphepha ukukhanya okuvela ekukhanyeni… Kufana “namehlo” eTV, echaphazela ngokuthe ngqo amava ethu aphambili okubukela iidrama kunye neemuvi.
I. Okokuqala, cacisa: Yintoni kanye kanye elawulwa yisisombululo se-optical?
Phantse zonke iimvakalelo zethu eziqondakalayo xa sibukele iTV zinxulumene nesisombululo se-optical, esilawula izinto ezintathu:
1. Ukukhanya okucacileyo nobumnyama: Akukho miboniso emnyama engwevu okanye imifanekiso eqaqambileyo ekhazimlayo. Umzekelo, xa ubukele imifanekiso yendalo yonkeIinkwenkwezi eziphakathi, ungahlula iinkcukacha ezimnyama ezijikeleze umngxuma omnyama ngaphandle kokuphoswa kukukhanya okunamandla kweenkwenkwezi;
2. Imibala yokwenyani: Imibala ebomvu yokwenyani, imibala eluhlaza okwesibhakabhaka yokwenyani, akukho "mbala" okanye "ukunyamalala." Umzekelo, xa ubukele idokhumentari malunga namahlathi emvula ashushu, umbala oluhlaza okwesibhakabhaka wamagqabi kunye nombala obomvu oqaqambileyo weentyatyambo unokubuyiselwa ukuze ubonakale njengokwenyani;
3. Ukuthintela ukuphazamiseka okunamandla: Akukho koyika ukukhanya okukufutshane. Umzekelo, xa amakhethini evuliwe emini okanye izibane zivuliwe ebusuku, umfanekiso uhlala ucacile kwaye awuyi koyiswa kukukhanya okukhanyayo.
II. Iintlobo eziqhelekileyo zezisombululo ze-optical: Ubuchwepheshe obahlukeneyo, amava ahlukeneyo kakhulu
Okwangoku, izisombululo ze-TV optical eziphambili zahlulwe zibe ziintlobo ezintathu, nganye ineemeko ezifanelekileyo kunye neemfuno zokusetyenziswa ezifanelekileyo:
1. Isisombululo se-Mini LED Optical: "Ukumkani oneenkcukacha" zolawulo lokukhanya oluchanekileyo
Olu “khetho oluqhelekileyo” kwiiTV ze-LCD eziphakathi ukuya kweziphezulu, kunye nenzuzo ephambili “yokulawula ukukhanya ngokuchanekileyo.” Umgaqo wayo ulula: amawaka eentsimbi ze-LED ezincinci zifakwe kumaleko we-backlight yeTV, kwaye ezi ntsimbi zahlulwe zaba “ziindawo ezincinci” ezininzi — kwiindawo ezinemifanekiso eqaqambileyo, iintsimbi kwiindawo ezihambelanayo ziyakhanya; kwiindawo ezinemifanekiso emnyama, iintsimbi kwiindawo ezihambelanayo ziyacima okanye zicime ngokupheleleyo.
Umzekelo, xa ubukele umboniso "we-dark corridor" kwimuvi eyoyikisayo, iiTV zemveli ziya kuba "nee-halos" ezijikeleze imiphetho ye-corridor ngenxa yokulawula ukukhanya okungacacanga, okwenza ibukeke ingwevu. Ngokwahlukileyo koko, isisombululo se-Mini LED sinokucima ngokuchanekileyo ii-beads ezingaphandle kwe-corridor, sikhanyise kuphela indawo ye-corridor, nto leyo ekhokelela kwiinkcukacha ezicacileyo ezimnyama kunye nomoya ogcwele ngokupheleleyo.
Uhlobo oluphucukileyo lwe-“RGB-Mini LED” luvumela amabala abomvu, aluhlaza, naluhlaza okwesibhakabhaka ukuba akhuphe ukukhanya ngokwawo, nto leyo esusa isidingo “sokulungiswa kwemibala exutyiweyo” njengezisombululo zemveli. Oku kufezekisa ukuchaneka okuphezulu kombala, okubonelela ngamava amangalisayo xa ubukele ii-animations okanye iidokhumentari ezinemibala etyebileyo.
2. Isisombululo se-Laser TV Optical: "Isigcini-sithuba" sabathandi besikrini esikhulu
Isisombululo sokubona seTV zelaser sahluke ngokupheleleyo kwiiTV zemveli: endaweni "yezikrini ezizikhanyisayo," zisebenzisa imithombo yokukhanya kwelaser ukubonisa imifanekiso kwizikrini ezikhethekileyo. Iingenelo zayo eziphambili "kukonga indawo, amandla esikrini esikhulu," kunye nokuphepha ukonakala kwamehlo ngenxa yokukhanya okuthe ngqo.
IiTV zelaser zakuqala zazineengxaki: zazinovelwano lokukhanya okukufutshane, zifuna ukuba amakhethini atsalwe emini ukuze abone ngokucacileyo. Ngoku, isizukulwana esitsha sezisombululo zelaser optical, ngokusebenzisa "uyilo lwendlela yokukhanya" olulungisiweyo kunye "nezinto zesikrini," zinokuvala ngaphezulu kwe-80% yokukhanya okukufutshane - nokuba izibane zivuliwe kwaye amakhethini avuliwe emini, umfanekiso uhlala ucacile kwaye ucacile, awusadingi kwamkela iimeko zokukhanya. Ngaphezu koko, ineemfuno zendawo ephantsi kakhulu, ekwaziyo ukubonisa isikrini esikhulu se-intshi ezili-100 ukusuka eludongeni, ivumela amagumbi okuhlala amancinci ukuba onwabele amava akwinqanaba lesinema.
3. Isisombululo se-LED esiqhelekileyo: Ukhetho olungabizi kakhulu
Esi sisisombululo esiqhelekileyo kwiiTV zasekuqaleni. Umgaqo waso "kukukhanyiswa kwezibane zangasemva," emva koko kusetyenziswa izihluzi kunye nee-diffusers ukusasaza ukukhanya ngokulinganayo. Inzuzo kukuba ixabiso liphantsi kwaye lifikeleleka, lihlangabezana ngokupheleleyo neemfuno zemihla ngemihla njengokubukela iindaba kunye needrama eziqhelekileyo; ingxaki kukuchaneka kokulawula ukukhanya, okubonakala kwimifanekiso emnyama engwevu kunye nee-halos, kunye nokuchaneka kombala okuphantsi kunezisombululo ezibini zangaphambili.
III. Ungayikhetha njani isisombululo se-optical xa uthenga iTV? Khumbula amanqaku amathathu alula
Akukho mfuneko yokubamba ngentloko iiparameters ezintsonkothileyo — qonda la manqaku mathathu ukuze uphephe imigibe:
1. Jonga "inani leendawo ezifiphalisayo" (kwiiTV ze-Mini LED): Ngobukhulu obufanayo, iindawo ezininzi zithetha ulawulo lokukhanya oluchanekileyo kunye neenkcukacha ezicacileyo zobumnyama. Umzekelo, iTV engama-intshi angama-85 eneendawo ezingaphezu kwama-500 inokuhlangabezana neemfuno zokubukela zemihla ngemihla, ngelixa iindawo ezingaphezu kwe-1000 zifanelekile kwabo bafuna umgangatho ophezulu womfanekiso;
2. Jonga "ubuchule bokulwa nokukhanya okukhanyayo" (kwiiTV zelaser): Xa uthenga, buza malunga "nomlinganiselo wokungafani kokukhanya okungqongileyo," okanye uvavanye ngqo evenkileni ukhanyise izibane. Ethembekileyo iya kukuvumela ukuba ubone ngokucacileyo iinkcukacha zomfanekiso ngaphandle kokukhanya okucacileyo;
3. Jonga "amava okwenyani okubukela" (aqhelekileyo): Nokuba iiparameter zilungile kangakanani na, kufuneka uhlale uzibukela ngokwakho — jonga ukuba imifanekiso emnyama ingwevu na, ukuba imibala yendalo na, kwaye ukuba imifanekiso eqaqambileyo iyakhazimla na. Ehambelana nemikhwa yakho yokubona yeyona ilungileyo.
IV. Isishwankathelo sokugqibela: Izisombululo ezibonakalayo aziyonto “eyimfihlakalo,” kodwa ngamava asebenzisekayo
Enyanisweni, izisombululo zokukhanya akufuneki zibe nzima kakhulu. Injongo yazo ephambili kukwenza ukukhanya kuqonde amehlo ethu ngcono: ukuvumela iindawo ezikhanyayo zikhanye, iindawo ezimnyama zibe mnyama, ukwenza imibala ifane neyokwenyani, nokusivumela ukuba sibukele imifanekiso ngokukhululekileyo nakweyiphi na indawo.
Ukuba ufuna umgangatho ophezulu wemifanekiso kwaye ubukela iimuvi rhoqo, khetha isisombululo se-RGB-Mini LED; ukuba ufuna isikrini esikhulu kwaye unegumbi lokuhlala elincinci, khetha i-laser yesizukulwana esitsha.Isisombululo seTV; ukuba ubukela iidrama imihla ngemihla kwaye unebhajethi encinci, isisombululo se-LED esiqhelekileyo sanele ngokupheleleyo. Ukuqonda izisombululo ze-optical kuya kukuthintela ekulahlekisweni "ngamacebo eeparameter" abathengisi xa uthenga iTV!
