Emphakathini wanamuhla, izibonisi ze-LED seziyingxenye ebalulekile yokuphila kwethu kwansuku zonke. Kusukela ekubonisweni kumaselula namakhompyutha ukuya ekubonisweniamabhodi amakhulufuthiizinkundla, ubuchwepheshe be-LED bukhona yonke indawo. Ngakho-ke, zingaki izinhlobo zezikrini ze-LED ezikhona? Lesi sihloko sizocubungula le nkinga ngokuningiliziwe, ngokuyinhloko ihlukanise kusukela kubukhulu obubili bokuhlukanisa: ukuhlukaniswa ngombala nokuhlukaniswa ngamayunithi ephikseli. Ngaphezu kwalokho, sizophinde singene ezinhlobonhloboizinzuzo zokubonisa LEDukuze abafundi baqonde kangcono futhi basebenzise lobu buchwepheshe.
1. Izinhlobo zezikrini ze-LED
1.1 Ukuhlukaniswa ngombala
Ngokuhlukaniswa kombala, izibonisi ze-LED zingahlukaniswa ngezinhlobo ezintathu:isikrini esinombala owodwa, isikrini esinemibala emibilifuthiisikrini esinombala ogcwele.
Isikrini se-Monochrome:Isikrini se-Monochrome sisebenzisa umbala owodwa kuphela wobuhlalu besibani se-LED, obuvame ukusetshenziswa kuwoukukhangisa kwangaphandle, izimpawu zomgwaqo neminye imikhakha. Ngokuvamile, kusetshenziswa okubomvu, okuluhlaza okotshani noma okuphuzi. Inzuzo enkulu ukuthi izindleko zokukhiqiza ziphansi futhi umphumela ubalulekile ezimweni ezithile zohlelo lokusebenza.
Isikrini esinemibala emibili:Isikrini esinemibala emibili sivamise ukwakhiwa ngobuhlalu belambu le-LED elibomvu neliluhlaza. Ngenhlanganisela ehlukene yale mibala emibili, uhla oluthile lwezinguquko zombala lungaboniswa. Izindleko zesikrini esinemibala emibili ziphansi kunesikrini esinombala ogcwele, kodwa ukuvezwa kombala kungcono kunesikrini se-monochrome. Ivame ukusetshenziselwa ukubonisa ulwazi emabhange, ezikoleni, njll.
Isikrini esinombala ogcwele:Isikrini esinombala ogcwele sakhiwe imibala emithathu yobuhlalu besibani se-LED: obomvu, oluhlaza okotshani noluhlaza okwesibhakabhaka. Ngokuhlanganiswa kwemibala ehlukene, ingabonisa imibala ecebile ngokwethembeka okuphezulu. Isetshenziswa kakhulu ezimeni zezicelo ezisezingeni eliphezulu njengokuboniswa kwencazelo ephezulu kanye nokudlalwa kwevidiyo, njengokuthiamakhonsathi amakhulu, ukusakazwa kwe-TV, njll.
1.2 Ukuhlelwa ngamayunithi ephikseli
Ngokusho kwamayunithi e-pixel ahlukene, izikrini ze-LED zingahlukaniswa zibe izikrini zezibani eziqondile,Izikrini ze-SMDfuthiizikrini ezincane ze-LED.
Isikrini esikhanyayo se-plug-in:Iphikseli ngalinye lesikrini esikhanyayo se-plug-in esiqondile siqukethe ubuhlalu besibani se-LED obubodwa noma ngaphezulu obuzimele, obufakwe ebhodini le-PCB ngamaphini. Lolu hlobo lwesikrini se-LED lunobuhle bokukhanya okuphezulu, impilo ende, ukumelana nesimo sezulu esiqinile, njll., futhi luvame ukusetshenziswa ekukhangisweni kwangaphandle kanye nezikhathi zokubonisa ezinkulu.
Isikrini se-SMD: Isikrini se-SMD sibizwa nangokuthi isikrini se-SMD, futhi iphikseli ngayinye yakhiwe ngobuhlalu besibani se-SMD LED. Ubuchwepheshe be-SMD buvumela ubuhlalu besibani se-LED ukuthi buhlelwe eduze, ngakho ukulungiswa kwesikrini se-SMD kuphezulu futhi isithombe sibucayi kakhulu. Izikrini ze-SMD zisetshenziselwa ikakhulukaziimibukiso yasendlini, njengamagumbi enkomfa, amahholo emibukiso, njll.
Isikrini se-Micro LED:Isikrini se-Micro LED sisebenzisa ama-chips e-LED amancane, amancane kakhulu ngosayizi, anokuminyana kwamaphikseli aphezulu nokusebenza kwesithombe esihle. Isikrini se-Micro LED siyisiqondiso sokuthuthukiswa kobuchwepheshe bokuboniswa kwesikhathi esizayo futhi sisetshenziswa kumadivayisi abonisa izinga eliphezulu njengamadivayisi e-AR/VR, ama-TV anencazelo ephezulu kakhulu, njll.
2. Izinzuzo zezibonisi ze-LED
2.1 Ukukhiqiza Umbala Wemvelo
Izibonisi ze-LED zisebenzisa ubuchwepheshe obuthuthukisiwe bokuphatha imibala ukukhiqiza kabusha imibala yemvelo ngokunembile. Ngokulungisa kahle imibala emithathu eyinhloko ebomvu, eluhlaza, noluhlaza okwesibhakabhaka, izibonisi ze-LED zingabonisa amaleveli ombala onothileyo kanye nemiphumela yesithombe engokoqobo. Kungakhathaliseki ukuthi isithombe esimile noma isithombe esiguqukayo, izibonisi ze-LED zinganikeza okuhlangenwe nakho okubonakalayo okuhle kakhulu.
2.2 Ukugqama Okukhaliphile Ukuguquguquka
Ukukhanya kwesibonisi se-LED kungalungiswa ngokuhlakanipha ngokuvumelana nezinguquko ekukhanyeni okuzungezile, okwenza isibonisi sinikeze izithombe ezicacile ngaphansi kwezimo ezihlukahlukene zokukhanya. Ezindaweni zokukhanya okuqinile, izibonisi ze-LED zinganikeza ukuphuma kokukhanya okuphezulu ukuze kuqinisekiswe ukubonakala kwesithombe; ezindaweni ezilufifi, ukukhanya kungancishiswa ukuze kuncishiswe ukusetshenziswa kwamandla nokukhathala kwamehlo.
2.3 Izinga lokuvuselela eliphezulu, isivinini sokuphendula esisheshayo
Izibonisi ze-LED zinamazinga aphezulu okuvuselela kanye nesivinini sokuphendula esisheshayo, okubaluleke kakhulu ekuboniseni okuqukethwe okuguquguqukayo. Amazinga aphezulu okuvuselela anganciphisa ukucwayiza nokugcotshwa kwesithombe, enze ukudlalwa kwevidiyo kube bushelelezi futhi kube bushelelezi. Isivinini sokuphendula esisheshayo siqinisekisa ukuthi isibonisi singabuyekeza isithombe ngesikhathi ukuze sigweme ukubambezeleka nokuba yiqhwa.
2.4 I-Grayscale Ephakeme
I-high grayscale ingenye yezimpawu ezibalulekile zezikrini zokubonisa ze-LED, ezinquma ileveli yombala nemininingwane engaboniswa isikrini. I-high grayscale ivumela izikrini zokubonisa ze-LED ukuthi zibonise imininingwane yesithombe esicebile ngisho nalapho ukukhanya kuphansi, ngaleyo ndlela kuthuthukise ikhwalithi yesithombe iyonke kanye nokuvezwa kombala.
2.5 Ukuhlanganisa okungenamthungo
Izikrini zokubonisa ze-LED zingafinyelela ukuhlanganisa okungenamthungo, okuzivumela ukuthi zinikeze izithombe eziqhubekayo nezihlanganisiwe uma ziboniswa endaweni enkulu. Ubuchwepheshe bokuhlanganisa okungenamthungo buqeda ukuphazamiseka komngcele wezikrini zendabuko zokuhlanganisa, okwenza isithombe siphelele futhi sihle. Izikrini zokubonisa ze-LED ezihlukaniswe ngaphandle komthungo zisetshenziswa kabanzi emakamelweni amakhulu enkomfa, izikhungo zokuqapha, imibukiso nezinye izikhathi.
2.6 Okubonwayo okunezinhlangothi ezintathu
Izikrini zokubonisa ze-LED zingaphinda zinikeze umuzwa obonakalayo wezinhlangothi ezintathu. Ngobuchwepheshe bokubonisa obukhethekile nama-algorithms, izikrini zokubonisa ze-LED zingalingisa imiphumela enezinhlangothi ezintathu, zenze izithombe zibe ngokoqobo futhi zicace. Akuthuthukisi nje kuphela ukuthokozela okubonwayo kwezithameli, kodwa futhi andisa inkambu yohlelo lokusebenza yezikrini zokubonisa ze-LED.
Isiphetho
Izibonisi ze-LED zingahlukaniswa ngezinhlobo eziningi ngokuya ngombala namayunithi wephikseli. Kungakhathaliseki ukuthi isikrini se-monochrome, isikrini esinemibala emibili noma isikrini esinemibala egcwele, isikrini sesibani se-direct-plug, isikrini se-SMD noma isikrini se-micro-LED, zonke zinezimo zohlelo lwazo kanye nezinzuzo. Izibonisi ze-LED zihamba phambili ekwenziweni kombala, ukukhanya okuphezulu, ukuphendula okusheshayo, indawo empunga ephezulu, ukuhlanganisa okungenamthungo kanye nolwazi olubonakalayo lwezinhlangothi ezintathu, futhi ziyinketho evamile yobuchwepheshe bokubonisa besimanje. Ngokuthuthuka okuqhubekayo kobuchwepheshe, izibonisi ze-LED zizobonisa amandla azo okusebenza aqinile emikhakheni eminingi.
