Isibonisi se-mini LED esiqondile sisebenzisa amandla amaningi kune-LCD

2024-10-09

I-LED encane intuthuko kuze kube manje, ngobuchwepheshe obukhula ngokukhula, ukukhanya kwayo okuphezulu, ukugqama kwayo okuphezulu, i-gamut yemibala ephezulu kanye nezinye izici kuye kwaqashelwa kabanzi kancane kancane ngabathengi. Kodwa-ke, kube nzima ukususa umbono ohlukile wokuboniswa okuqondile kwe-LED "kwabathengi bamandla".

Ngakho-ke, ikuphi inkolelo-mbono ye I-Mini LEDUkusetshenziswa kwamandla aphezulu kuvela kuphi?

Ngakolunye uhlangothi, ama-LED chips endabuko makhulu futhi awasebenzi kahle. Isikrini se-LED esivamile empilweni yansuku zonke siseyisibonisi se-SMD LED sama-particle patches amakhulu. Lolu hlobo lwesibonisi se-SMD lwakhiwe ngephakheji elihle lama-light beads, i-light chip esetshenziswa kuma-lamp beads inkulu kakhulu kune-Mini LED chip, futhi ukusebenza kahle okukhanyayo kanye nokusebenza kahle kokushabalalisa ukushisa kuphansi kakhulu.

I-Mini LED flip chip inokukhanya okuphezulu nokusebenza kahle okukhanyayo kune-chip enkulu esetshenziswa ku-SMD yendabuko (1010/1212/1515, njll.); Ngakho-ke, ngaphansi kwezimo ezifanayo, I-LED encane Ukusetshenziswa kwamandla kwe-flip chip nakho kuphansi.

Ngakolunye uhlangothi, ama-LED angaphandle ashiya umbono ohlukile. Ukuboniswa okuqondile kwe-LED ensimini yokuboniswa kwangaphakathi akukadluli isikhathi eside, futhi umqondo wendabuko wokuboniswa okuqondile kwe-LED uvame kakhulu ngaphandle. Ukuboniswa okujwayelekile kwangaphakathi, kungaba yi-LCD noma I-LED, ukukhanya ku-200-400nit kwanele, kodwa ngenxa yezidingo zezentengiselwano, ukukhanya okudingeka yi-LED yangaphandle kuphakeme kaningi kuneyangaphakathi, kufinyelela ku-8000 noma ngisho ku-10000nit, ukusetshenziswa kwamandla ngokwemvelo akufani. Futhi indawo yesikrini sokubonisa sasekhaya nayo iphindwe kaningi kunesikrini sangaphakathi, ngakho-ke i-LED ishiya umbono wokuthi akukhona nje kuphela ukushisa okubi kakhulu, kodwa ukusetshenziswa kwamandla kwesikrini sonke nakho kuphakeme kakhulu.

Kungani i-liquid crystal idla amandla amaningi kunombono?

Ngoba I-LCD ayikwazi ukucima ungqimba lwesibani sangemuva. Ukuboniswa kwekristalu eliwuketshezi kufezwa izinhlelo ezimbili ezahlukene: isibani sangemuva sinesibopho sokunikeza ukukhanya, kanti ama-molecule ekristalu eliwuketshezi alawula ukushintsha kombala, ukukhanya kanye nobumnyama ngokuphambuka. Ngakho-ke, inqobo nje uma i-LCD ivuliwe, kungakhathaliseki ukuthi yisiphi isikrini esiboniswayo, noma ngabe kuyisikrini esimnyama, ungqimba lwesibani sangemuva belulokhu lukhanya njalo futhi luqinile, futhi alukwazi ukulungiswa noma ukuvalwa ngokukhululekile.

Isibonisi esiqondile se-LED sizikhanyisa ngokwaso yi-chip ye-LED, ukukhanya nombala kuqhutshwa ngqo yi-current kanye ne-voltage. I-LED i-chip okufanele uyifinyelele, amaphikseli amnyama ukukhanya okuphansi, ukusetshenziswa kwamandla okuphansi, amaphikseli amnyama awakhiphi ukukhanya, ukusetshenziswa kwamandla akusebenzi.
