"A taƙaice dai, mafita ta gani ita ce tsarin hanyoyin da TV ke amfani da su don "mayar da haske": yadda ake yin haske daidai da hotuna, yadda ake nuna launuka a zahiri, yadda ake guje wa haske daga haske… Kamar "idanu" na TV ne, wanda ke shafar ainihin ƙwarewarmu ta kallon wasan kwaikwayo da fina-finai kai tsaye.
I. Da farko, a fayyace: Menene ainihin maganin gani ke sarrafawa?
Kusan dukkan motsin zuciyarmu lokacin kallon talabijin yana da alaƙa da maganin gani, wanda galibi ke sarrafa abubuwa uku:
1. Haske mai haske da duhu: Babu wasu wurare masu launin toka ko kuma wurare masu haske masu haske. Misali, lokacin kallon abubuwan da ke faruwa a sararin samaniyaTsakanin taurari, za ka iya bambance duhun da ke kewaye da ramin baƙi ba tare da hasken taurarin ya makantar da kai ba;
2. Launuka na gaskiya: Ja na gaskiya, shuɗi na gaske, babu "launi" ko "ɓacewa." Misali, lokacin kallon wani shirin gaskiya game da dazuzzukan ruwan sama na wurare masu zafi, ana iya mayar da kore mai launin shuɗi na ganye da ja mai haske na furanni su yi kama da na gaske;
3. Ƙarfin hana tsangwama: Ba ya jin tsoron hasken da ke kewaye. Misali, idan aka buɗe labule da rana ko kuma aka kunna fitilu da daddare, hoton zai kasance a sarari kuma ba zai shagaltu da hasken ba.
II. Nau'ikan mafita na gani da aka saba amfani da su: Fasaha daban-daban, gogewa daban-daban
A halin yanzu, manyan hanyoyin samar da hasken TV galibi an raba su zuwa nau'i uku, kowannensu yana da yanayi mai dacewa da buƙatun amfani masu dacewa:
1. Magani Mai Sauƙi na LED: "Sarkin cikakken bayani" na daidaitaccen sarrafa haske
Wannan shine "zaɓin farko" ga talabijin na LCD masu matsakaicin zuwa manyan, tare da babban fa'idar "sarrafa haske daidai." Ka'idarsa mai sauƙi ce: an sanya dubban ƙananan beads na LED a cikin layin hasken baya na TV, kuma waɗannan beads an raba su zuwa "ƙananan yankuna" da yawa - a cikin wuraren hotuna masu haske, beads a cikin yankunan da suka dace suna haske; a cikin wuraren hotuna masu duhu, beads a cikin yankunan da suka dace suna duhu ko ma suna kashe gaba ɗaya.
Misali, lokacin kallon wani yanayi na "dark corridor" a cikin fim ɗin ban tsoro, talabijin na gargajiya za su yi "halos" a gefunan corridor saboda rashin daidaitaccen sarrafa haske, wanda hakan zai sa ya yi kama da launin toka. Sabanin haka, mafita ta Mini LED za ta iya kashe ƙwallo a wajen corridor daidai, tana haskaka yankin corridor kawai, wanda ke haifar da cikakkun bayanai masu duhu da kuma yanayi mai cike da nutsuwa.
Bambancin "RGB-Mini LED" mai ci gaba yana ba da damar beads ja, kore, da shuɗi su fitar da haske daban-daban, wanda hakan ke kawar da buƙatar "daidaitaccen launi" kamar mafita na gargajiya. Wannan yana cimma daidaiton launi mafi girma, yana ba da ƙwarewa mai ban mamaki yayin kallon zane-zane ko shirye-shiryen shirye-shirye masu launuka masu kyau.
2. Maganin Laser TV Optical: "Mai ceton sarari" ga masoyan manyan allo
Maganin gani na talabijin na laser ya bambanta gaba ɗaya da talabijin na gargajiya: maimakon "allon da ke haskaka kai," suna amfani da tushen hasken laser don nuna hotuna a kan allo na musamman. Babban fa'idodinsa sune "ƙarfin adana sarari, babban allo," da kuma guje wa lalacewar ido daga haske kai tsaye.
Talabijin na laser na farko suna da matsala: suna da saurin kamuwa da hasken da ke kewaye da su, suna buƙatar a zana labule da rana don gani sosai. Yanzu, sabuwar hanyar maganin laser, ta hanyar ingantaccen "ƙirar hanyar haske" da "kayan allo," na iya toshe fiye da kashi 80% na hasken da ke kewaye da su - koda kuwa an kunna fitilu kuma an buɗe labule da tsakar rana, hoton ya kasance a bayyane kuma a bayyane, ba ya buƙatar daidaita yanayin haske. Bugu da ƙari, yana da ƙarancin buƙatun sarari, yana iya nuna babban allo mai inci 100 kawai daga bango, wanda ke ba ƙananan ɗakunan zama damar jin daɗin ƙwarewar matakin sinima.
3. Maganin Hasken LED na yau da kullun: Zaɓin da ya fi araha
Wannan mafita ce gama gari ga talabijin masu matakin shiga. Ka'idarta ita ce "hasken bayan gida gaba ɗaya," sannan amfani da matattara da masu watsawa don yaɗa haske daidai gwargwado. Fa'idar ita ce ƙarancin farashi da araha, biyan buƙatun yau da kullun kamar kallon labarai da wasan kwaikwayo na yau da kullun; rashin amfanin shine rashin daidaiton sarrafa haske, mai saurin kamuwa da duhun launin toka da halos, tare da ƙarancin daidaiton launi fiye da mafita biyu na baya.
III. Yadda ake zaɓar maganin gani yayin siyan talabijin? Ka tuna da abubuwa 3 masu sauƙi
Ba sai an haddace sigogi masu rikitarwa ba - a fahimci waɗannan abubuwa guda uku domin a guji matsaloli:
1. Duba "adadin yankunan rage haske" (ga Mini LED TVs): Don girman iri ɗaya, ƙarin yankuna yana nufin ingantaccen sarrafa haske da cikakkun bayanai masu duhu. Misali, talabijin mai inci 85 mai yankuna sama da 500 zai iya biyan buƙatun kallo na yau da kullun, yayin da yankuna sama da 1000 suka dace da waɗanda ke neman ingancin hoto na ƙarshe;
2. Duba "ƙarfin hana walƙiya" (ga talabijin na laser): Lokacin siya, tambaya game da "rabowar bambancin hasken yanayi," ko gwada shi kai tsaye a cikin shago tare da fitilun da ke kunne. Wanda aka dogara da shi zai ba ku damar ganin cikakkun bayanai na hoto ba tare da nuna haske a bayyane ba;
3. Duba "ainihin kwarewar kallo" (na duniya): Komai kyawun sigogin, ya kamata ku kalli shi da kanku - duba ko duhun yanayi launin toka ne, ko launuka na halitta ne, kuma ko kyawawan yanayi suna da ban sha'awa. Wanda ya dace da halayen gani shine mafi kyau.
IV. Takaitaccen Bayani: Maganin gani ba “abin mamaki ba ne,” amma ƙwarewa ce mai amfani.
A gaskiya ma, hanyoyin gani ba sai sun zama masu rikitarwa ba. Babban manufarsu ita ce "sa haske ya fahimci idanunmu sosai": barin wurare masu haske su haskaka, duhun wurare ya dusashe, sanya launuka kusa da gaskiya, da kuma ba mu damar kallon hotuna cikin kwanciyar hankali a kowace muhalli.
Idan kana neman ingancin hoto mafi kyau kuma kana yawan kallon fina-finai, zaɓi mafita ta RGB-Mini LED; idan kana son babban allo kuma kana da ƙaramin falo, zaɓi sabon laser na zamaniMafita ta talabijin; idan kana kallon wasan kwaikwayo ne kawai a kowace rana kuma kana da ƙarancin kasafin kuɗi, maganin LED na yau da kullun ya isa gaba ɗaya. Fahimtar hanyoyin gani zai hana ka ruɗewa da "ma'anonin siga" na 'yan kasuwa lokacin siyan TV!
