Isikrini esicacileyo se-LED esincinci yimveliso entsha eye yaphucula isisombululo sayo kwisikrini sokucoca igama le-LED.Ke luhlobo luni lwesithuba esinokuluthetha njengesikrini esincinci?Xa isithuba sendawo ye-LED yesikrini esicacileyo esincinci singaphantsi kwe-P2.5, sinokuthi i-LED encinci iyabonakala.Okwangoku, ezi ngxaki ziphambili zintathu zilandelayo ekusetyenzisweni kwezikrini ezicacileyo ze-LED ezincinci kwimarike kufuneka ziphuculwe:
1. Ukunyuka kweepikseli ezifileyo okubangelwa kukuphuculwa komgangatho womfanekiso
Isikrini esicacileyo se-LED esincinci senziwe ngamaso amaninzi esibane se-LED, kwaye ukuhanjiswa kuxinene.Okukhona inani lamaso isibane se-LED kwindawo nganye yeyunithi, kokukhona umgangatho wesikrini esicacileyo, kunye nokutyeba kokuboniswa kweenkcukacha zomfanekiso.Nangona kunjalo, ngenxa yeziphene zobuchwephesha, izikrini ezicacileyo ezincinci zepitch zithandeka kwiindawo ezifileyo zamaso ezibane.Ngokuqhelekileyo, umgangatho wokukhanya kwe-LED ubonisa izinga lokufa lilawulwa ngaphakathi kwe-3 / 10,000, kodwa kwizikrini ezincinci ze-LED ezicacileyo, izinga lokufa kwe-3 / 10,000 lilinganiselwe.Umlinganiselo wesibane awukwazi ukuhlangabezana neemfuno zokusetyenziswa kwansuku zonke.Thatha isikrini esicacileyo se-P2 esincinci se-LED njengomzekelo, kukho amaso angama-250,000 wesibane kwisikwere semitha.Ukucinga ukuba indawo yesikrini i-4 square metres, inani lezibane ezifileyo liya kuba yi-25 * 3 * 4 = 300, eya kuzisa amava okubukela okungenabubele kwisiboniso esiqhelekileyo sesikrini.
Isisombululo: Isibane esifileyo ngokuqhelekileyo sisizathu sokuwelding okubuthathaka kwamaso esibane.Kwelinye icala, itekhnoloji yemveliso yomenzi wesikrini ocacileyo we-LED ayifikanga kumgangatho, kwaye kukho ingxaki ngokuhlolwa komgangatho.Kakade ke, ingxaki yezibane zesibane ayilawulwa.Ke ngoko, abavelisi kufuneka balawule umgangatho wezinto eziluhlaza ngokwenkqubo yokuhlola umgangatho osemthethweni, kwaye kwangaxeshanye babeke iliso kwinkqubo yokuvelisa.Phambi kokushiya umzi-mveliso, kufuneka kwakhona enze uvavanyo lokuguga lweeyure ezingama-72, uhlengahlengiso kwaye ujonge ingxaki yokukhanya okufileyo, kwaye uqiniseke ukuba yimveliso efanelekileyo phambi kokuthunyelwa.
2. Ilahleko yegreyscale ebangelwa kukuncipha kokuqaqamba
Owona mahluko ubalulekileyo phakathi kwezicelo zokubonisa zangaphakathi nangaphandle lutshintsho kukukhanya okungqonge.Xa isikrini se-LED singena ngaphakathi, ukukhanya kwaso kuyafuneka, kodwa xa ukuqaqamba kwesikrini esibonakalayo kwehla ngaphantsi kwe-600cd/㎡, isikrini siqala ukubonisa ilahleko engwevu.Njengoko ukukhanya kuncipha ngakumbi, ilahleko yegreyscale nayo iyanda.ngakumbi nangakumbi enzulu.Siyazi ukuba ngokukhona inqanaba elingwevu liphezulu, kokukhona ityebile imibala eboniswa kwiscreen esicacileyo, kwaye kokukhona ubuthathaka kwaye ugcwele umfanekiso.
Isisombululo: Ukukhanya kwesikrini kulungele ukuqaqamba kwe-ambient kwaye kunokulungiswa ngokuzenzekelayo.Ziphephe iimpembelelo eziqaqambileyo okanye ezimnyama kakhulu ukuze uqinisekise umgangatho womfanekiso oqhelekileyo.Ngexesha elifanayo, isikrini esinezinga eliphezulu legrey samkelwa, kwaye inqanaba langoku elingwevu linokufikelela kwi-16bit.
3. Ingxaki yokufudumeza okubangelwa kukujonga ngokusondeleyo
Uphononongo lubonise ukuba kwinkqubo yokuguqulwa kwamandla kwizikrini ze-LED, ukuguqulwa kokuguqulwa kwe-electro-optical kumalunga ne-20 ~ 30% kuphela, oko kukuthi, kuphela malunga ne-20 ~ 30% yegalelo lamandla ombane aguqulwa abe amandla okukhanya, kwaye i-70 ~ 80% eseleyo yamandla.Zonke zidliwe ngendlela yemitha ye-thermal, ngoko ke, ubushushu bomboniso we-LED bunzulu.Isikrini esicacileyo se-LED esincinci esivelisa ubushushu ixesha elide siya kubangela ukuba ubushushu be-ambient bangaphakathi bunyuke.Kubasebenzi bangaphakathi, ukuhlala ixesha elide kuya kuba nzima, kwaye nokuba uhlala kwindawo ekude, kunzima ixesha elide.Gcina isimo sengqondo esihle phantsi komkhuhlane.
Isisombululo: Ukusetyenziswa komgangatho ophezulu wokunikezelwa kwamandla aphezulu kunokuqinisekisa izinga eliphezulu lokuguqulwa kwe-electro-optical, ngaloo ndlela kuncitshiswe impembelelo yobushushu.
Ukuba ezi ngxaki zintathu zinkulu zezikrini ezicacileyo ze-LED zisonjululwe ngokufanelekileyo, aziyi kuchaphazela amava okusetyenziswa kwezikrini ezicacileyo ze-LED.Ukuba ufuna ukwazi ngakumbi malunga nezikrini ezicacileyo ze-LED, nceda ushiye umyalezo kwaye usixelele
