Saka, mufananidzo wekuti Mini LED's kushandiswa kwesimba kwakanyanya kunobva kupi?

Kune rumwe rutivi, machipisi e LED echinyakare akakura uye haashande zvakanaka. Chiratidziro che LED chinowanzoonekwa muhupenyu hwezuva nezuva chichiri chiratidziro che LED cheSMD chezvigamba zvikuru. Rudzi urwu rwechiratidziro cheSMD runoumbwa nepakeji yakanaka yemabhera echiedza, chipande chechiedza chinoshandiswa mumabhera emwenje chakakura kupfuura chipande che Mini LED, uye kushanda zvakanaka kwechiedza uye kupisa kwakaderera zvikuru.

Chip yeMini LED flip ine kupenya kwakanyanya uye inoshanda zvakanaka kupfuura chip hombe inoshandiswa muSMD yechinyakare (1010/1212/1515, nezvimwewo); Saka, mumamiriro ezvinhu akafanana, Mini LED Kushandiswa kwesimba remachipisi echip kwakadererawo.

Kune rumwe rutivi, ma LED ekunze anosiya mufananidzo wekare. Kuratidzwa kwakananga kwe LED munzvimbo yekuratidzira yemukati hakuna kutora nguva yakareba, uye pfungwa yechinyakare yekuratidzira kwakananga kwe LED yakajairika munzvimbo dzekunze. Kuratidzwa kwakajairika kwemukati, kungave LCD kana LED, kupenya mu 200-400nit kwakakwana, asi nekuda kwezvinodiwa zvemabhizinesi, kupenya kunodiwa ne LED yekunze kwakakwira kakapetwa kagumi kupfuura yemukati, kusvika 8000 kana kunyange 10000nit, kushandiswa kwesimba hakusi kwakafanana. Uye nzvimbo yechidzitiro chekuratidzira kumba yakapetwa kagumi nemazana kupfuura yechidzitiro chemukati, saka LED inosiya pfungwa yekuti kwete kupisa chete kwakakomba, asi kushandiswa kwesimba rechidzitiro kwakakwirawo zvakanyanya.

Sei kristaro yemvura ichidya simba rakawanda kupfuura pfungwa?

Nekuti LCD haikwanise kudzima backlight layer. Kuratidzwa kwe liquid crystal kunowanikwa nemasisitimu maviri akasiyana: backlight ine basa rekupa kupenya, uye liquid crystal molecules inodzora ruvara, chiedza nekuchinja kwerima nekutsauka. Saka, chero bedzi LCD yakabatidzwa, zvisinei nekuti ndeipi skrini inoratidzwa, kunyangwe iri dema screen, backlight layer yagara iri chiedza chakasimba uye chakasimba, uye haigone kugadziriswa kana kuvharwa zvakasununguka.

Chiratidziro che LED chakananga chinozvijekesera chega ne LED chip, kupenya neruvara zvinotungamirirwa zvakananga nemagetsi nemagetsi. LED Chip kuti isvike, mapikiseti matema chiedza chidiki, simba shoma rinoshandiswa, mapikiseti matema haaburitse chiedza, simba harishandiswi.
