Ukukhanya kwawo nokugqama kwawo kuqhathaniswa namathelevishini e-OLED, kodwa izindleko zawo ziphansi kakhulu futhi abukho ubungozi bokushiswa kwesikrini.

Ngakho-ke iyini ngempela i-Mini LED?

Njengamanje, i-Mini LED esixoxa ngayo ayiyona ubuchwepheshe obusha obusha ngokuphelele, kodwa isisombululo esithuthukisiwe njengomthombo we-backlight we-liquid crystal displays, engaqondwa njengokuthuthukiswa kobuchwepheshe be-backlight.

Ama-TV amaningi e-LCD asebenzisa i-LED (Light Emitting Diode) njengesibani sangemuva, kuyilapho ama-Mini LED TV esebenzisa i-Mini LED, umthombo wokukhanya omncane kunama-LED avamile.Ububanzi be-Mini LED bulinganiselwa ku-200 microns (0.008 amayintshi), okuyingxenye eyodwa kwezinhlanu zosayizi we-LED ojwayelekile osetshenziswa kumaphaneli e-LCD.

Ngenxa yobuncane bazo, zingasatshalaliswa kakhulu kuso sonke isikrini.Uma kunokukhanya kwangemuva kwe-LED okwanele esikrinini, isilawuli sokukhanya, i-gradient yombala, nezinye izici zesikrini zingalawulwa kahle ngokwanele, ngaleyo ndlela kunikeze ikhwalithi yesithombe engcono.

Futhi i-Mini LED TV yangempela isebenzisa i-Mini LED ngokuqondile njengamaphikseli esikhundleni sokukhanya kwangemuva.AbakwaSamsung bakhiphe i-110 inch Mini LED TV ku-CES 2021, ezokwethulwa ngoMashi, kodwa kunzima ukubona imikhiqizo esezingeni eliphezulu kangaka ivela emizini eminingi.

Yimaphi amabhrendi ahlela ukwethula imikhiqizo ye-Mini LED?

Sesibonile ku-CES yalo nyaka ukuthi i-TCL isikhiphe i-“ODZero” Mini LED TV.Eqinisweni, i-TCL iphinde yaba ngumkhiqizi wokuqala ukwethula ama-Mini LED TVs.Ama-TV e-LG's QNED TV ethulwe ku-CES nama-Neo QLED TV akwa-Samsung nawo asebenzisa ubuchwepheshe be-Mini LED backlight.

Yini engalungile nge-Mini LED backlight?

1, Isendlalelo sokuthuthukiswa kokukhanya kwangemuva kwe-Mini LED

Njengoba i-China ingena esigabeni sokujwayelekile sokuvimbela nokulawula ubhubhane, inkambiso yokubuyisela ukusetshenziswa iyaqina kancane kancane.Uma ubheka emuva ngo-2020, "umnotho wasekhaya" ngokungangabazeki uyisihloko esishisayo esikhulu kunazo zonke emkhakheni wabathengi, futhi "umnotho wasekhaya" uthuthukile, kuyilapho futhi usekela ukukhula okuphelele kobuchwepheshe obusha bokubonisa obufana ne-8K, amachashazi we-quantum, ne-Mini LED. .Ngakho-ke, ngokukhuthazwa okuqinile kwamabhizinisi ahamba phambili afana ne-Samsung, LG, Apple, TCL, kanye ne-BOE, ama-Mini TV anencazelo ephezulu kakhulu asebenzisa ukukhanya kwe-Mini LED backlight aphenduke indawo yomkhakha.Ngo-2023, kulindeleke ukuthi inani lemakethe lamabhodi angemuva e-TV asebenzisa ukukhanya kwe-Mini LED lifinyelele kumadola ayizigidi eziyizinkulungwane ezingu-8.2, kanti u-20% wenani lezindleko lingama-Mini LED chips.

I-Mini LED ekhanyayo engemuva eqondile inezinzuzo zokucaca okuphezulu, ubude besikhathi sokuphila, ukusebenza kahle kokukhanya okuphezulu, nokuthembeka okuphezulu.Ngesikhathi esifanayo, i-Mini LED, ehlanganiswe nokulawulwa kwendawo yokufiphaza kwendawo, ingafinyelela i-HDR ehluke kakhulu;Kuhlanganiswe namachashazi anombala ophakeme we-gamut quantum, umbala obanzi we-gamut>110% we-NTSC ungafinyelelwa.Ngakho-ke, ubuchwepheshe be-Mini LED budonse ukunakwa okuningi futhi baba umkhuba ongenakugwemeka kwezobuchwepheshe nokuthuthukiswa kwemakethe.

2, Imingcele ye-chip ye-backlight ye-mini LED

I-Guoxing Semiconductor, inkampani ephethwe ngokugcwele ye-Guoxing Optoelectronics, ithuthukise i-Mini LED epitaxy kanye nobuchwepheshe be-chip emkhakheni wezinhlelo zokusebenza ze-Mini LED backlight.Ukuphumelela okubalulekile kwezobuchwepheshe kwenziwe ekuthembekeni komkhiqizo, ikhono le-anti-static, ukuzinza kwe-welding, nokungaguquguquki kombala okhanyayo, futhi uchungechunge olubili lwemikhiqizo ye-Mini LED backlight chip, ehlanganisa i-1021 ne-0620, yenziwe.Ngesikhathi esifanayo, ukuze uvumelane kangcono nezidingo zokupakishwa kwe-Mini COG, i-Guoxing Semiconductor ithuthukise umkhiqizo omusha we-high-voltage 0620, ehlinzeka amakhasimende ngezinketho eziningi.

3. Izici ze-Mini LED backlight chip

1. Idizayini yesakhiwo se-epitaxial ephezulu engaguquguquki, enekhono eliqinile le-chip

Ukuze kuthuthukiswe i-wavelength concentration ye-Mini LED backlight chips, i-Guoxing Semiconductor isebenzisa ubuchwepheshe bokulawula ukucindezeleka kwe-epitaxial layer obuhlukile ukuze kuncishiswe ingcindezi yangaphakathi nokuqinisekisa ukuvumelana enqubweni yokukhula komthombo we-quantum.Mayelana nama-chips, isixazululo se-DBR flip chip esenziwe ngokwezifiso nesithembeke kakhulu sisetshenziswa ukuze kuzuzwe amandla aphezulu e-anti-static.Ngokwemiphumela yokuhlolwa yelabhorethri yenkampani yangaphandle, ikhono eliphikisayo le-Guoxing Semiconductor Mini LED backlight chip lingadlula i-8000V, futhi ukusebenza kwe-anti-static komkhiqizo kufinyelela phambili embonini.
