Enkathini yanamuhla yedijithali, Isibonisi se-LEDsezibe yingxenye ebalulekile yezimpilo zethu, kusukela kumabhodi amakhulu kuya ezinhlelweni zokuzijabulisa zasekhaya. Kodwa-ke, akuzona zonkeIsibonisi se-LEDzadalwa zilingana. Ukwazi ukuthi ungayibona kanjani ikhwalithi yalezi zibonisi kubalulekile ekwenzeni isinqumo sokuthenga esinolwazi. Kulesi sihloko, sizohlola izici eziyisishiyagalolunye eziyisisekelo ezichaza ikhwalithiIsibonisi se-LEDngokuvamile, kulandelwa izici ezengeziwe eziqondene nezibonisi ze-LED ezicacile.
1. Ukuthamba
Isici sokuqala okufanele usicabangele lapho uhlolaIsibonisi se-LEDukuthamba kwayo.Isikrini se-LED sekhwalithi ephezulu kufanele ibe nobuso obuyisicaba ngokuphelele. Noma yikuphi ukuphambuka noma ukungalingani kuzoholela esithombeni esiphambene kanye nesipiliyoni sokubuka esibi ngokuphelele. Ukuze uhlole ukuthi siyisicaba, ungahlola isikrini ngamehlo kusuka kuma-engeli namabanga ahlukene. Isikrini esiyisicaba sizohlinzeka ngesithombe esifanayo ngaphandle kwamaqhubu noma ukucwila okubonakalayo.
2. Ukukhanya kanye ne-engeli yokubuka
Ukukhanya kungenye into ebalulekile ekunqumeni ikhwalithi yesibonisi se-LED.Isikrini se-LEDkufanele kube nokukhanya okuphezulu ukuze kubonakale ngokucacile ezimweni ezahlukahlukene zokukhanya. Ama-engeli okubuka nawo abalulekile; isibonisi esihle kufanele sigcine ukunemba kombala nokukhanya ngisho noma sibukwa ohlangothini. Ukuze uhlole lokhu, yima ngama-engeli ahlukene ubone ukuthi isithombe sisakhanya futhi sicacile yini.
3. Umphumela webhalansi emhlophe
Ibhalansi emhlophe ibalulekile ekumeleleni imibala ngendlela efanele.Isibonisi se-LEDkufanele kubonakale kumhlophe qwa, kungenambala. Ukuze uhlole lokhu, bonisa isithombe esimhlophe qwa bese ubheka ukuthi sibonakala simhlophe noma sinombala ophuzi, oluhlaza okwesibhakabhaka, noma oluhlaza. Isikrini esilinganiswe kahle sizobonisa umbala omhlophe ongathathi hlangothi, siqinisekise ukuthi yonke imibala imelwe ngokunembile.
4. Ukubuyiselwa kombala
Ukukhiqiza kabusha umbala kubhekisela ekhonweni le-Isibonisi se-LEDukukhiqiza kabusha imibala ngokwethembeka. Isikrini sekhwalithi ephezulu kufanele sibonise imibala ecacile, efana nempilo. Ukuze uhlole lokhu, qhathanisa imibala esikrinini nezinto zangempela noma ishadi lokubhekisela kombala. Uma imibala ibonakala ingacacile noma iphambene, isibonisi cishe asisekhwalithi ephezulu.
5. Ibala elithambile noma elifile
Esinye sezinkomba ezibaluleke kakhulu ze-Isibonisi se-LEDikhwalithi ukuba khona kwama-mosaic noma ama-pixel afile. Lezi yizindawo zesikrini ezingakhanyisi noma ezingabonisi imibala engalungile. Ikhwalithi enhleIsibonisi se-LED akufanele kube nama-pixel afile noma imiphumela ye-mosaic. Ukuze uhlole lokhu, bonisa isithombe sombala oqinile bese ubona ukuthi kukhona yini ukungahambisani. Uma uthola noma yimaphi ama-pixel afile, kungase kubonise isikrini sekhwalithi embi.
6. Amabhulokhi Ombala
Ukuvimba imibala yilapho imibala ivela emabhulokini ahlukene esikhundleni sokuxuba kahle. Isibonisi se-LED kufanele kube nokushintshashintsha okungenamthungo phakathi kwemibala. Ukuze uhlole ukuvimba kombala, bonisa isithombe se-gradient bese ubheka ukuthi imibala ihlangana kahle yini noma ukuthi kunemigqa noma amabhlogo abonakalayo. Isibonisi sekhwalithi ephezulu sizobonisa i-gradient ebushelelezi ngaphandle kwezinguquko ezisheshayo.
7. Ukuvumelana kobude begagasi
Ubude besikhathi bokukhanya obukhishwa yi-Isibonisi se-LEDinquma ubumsulwa kanye nokuvumelana kombala. Ikhwalithi enhle Isibonisi se-LEDkufanele ikhiphe ukukhanya kobude be-wavelength obuthile obuhambisana nombala omsulwa. Ukuze uhlole lokhu, ungasebenzisa i-colorimeter noma i-spectrometer ukukala ubude be-wavelength obukhishwa yisibonisi. Ububanzi be-wavelength obuhambisanayo bubonisa isikrini sekhwalithi ephezulu.
8. Ukusetshenziswa kwamandla ngemitha yesikwele
Ukusetshenziswa kwamandla kuyisici esibalulekile okufanele sicatshangelwe, ikakhulukazi ezikrinini ezinkulu. Isibonisi se-LED esisezingeni eliphezulu kufanele sibe nokusetshenziswa kwamandla okuphansi ngemitha yesikwele ngenkathi sisanikeza ukukhanya nokusebenza okuphezulu. Lokhu akugcini nje ngokunciphisa izindleko zokusebenza kodwa futhi kunciphisa nomthelela emvelweni. Hlola imininingwane yesibonisi ukuze uqhathanise amazinga okusetshenziswa kwamandla.
9. Izinga lokuvuselela
Izinga lokuvuselela le-Isibonisi se-LED kubalulekile ekunyakazeni okubushelelezi kanye nokunciphisa ukufiphala. Izinga lokuvuselela eliphezulu liholela esithombeni esibushelelezi, ikakhulukazi ngokuqukethwe okuhamba ngokushesha. IkhwalithiIsibonisi se-LED kufanele ibe nesilinganiso sokuvuselela okungenani esingu-60Hz. Ukuze uvivinye lokhu, bukela ividiyo noma i-animation ehamba ngokushesha esikrinini bese uhlola noma yikuphi ukufiphala noma ukukhanya.
10. Umehluko
Isilinganiso sokungafani silinganisa umehluko phakathi kwezingxenye ezimnyama kakhulu nezilula kakhulu zesithombe. Ikhwalithi ephezuluIsibonisi se-LED kufanele ibe nesilinganiso sokungafani okuphezulu ukuze kufinyelelwe kumnyama okujulile kanye nokumhlophe okukhanyayo. Ukuze uhlole lokhu, bonisa isigcawu esiqukethe izinto ezimnyama nezikhanyayo bese ubheka ukujula komnyama kanye nokukhanya komhlophe. Isilinganiso esihle sokungafani sithuthukisa ulwazi lokubuka lulonke.
11. Izinga lokushisa lombala
Izinga lokushisa lombala libhekisela ekufudumaleni noma ekupholeni kokukhanya okukhishwa yisibonisi. IkhwalithiIsibonisi se-LEDkufanele ibe nokushisa kombala okulungisekayo okungalinganiswa ezindaweni ezahlukene zokubuka. Ukuze uvivinye lokhu, lungisa ukulungiselelwa kokushisa kombala bese ubona ukuthi isithombe sishintsha kanjani. Ukuboniswa kwekhwalithi kuzovumela amazinga okushisa ombala ahlukahlukene ngaphandle kokubeka engcupheni ikhwalithi yesithombe.
12.Isibonisi sangaphakathi esincane: ukukhanya okuphansi, i-grayscale ephezulu
Ngobaizibonisi ze-LED zangaphakathi ezithambile, kunezici ezimbili ezengeziwe okufanele uzicabangele: ukukhanya okuphansi kanye nokumpunga okuphezulu. Lezi zibonisi zenzelwe ukubuka eduze, ngakho ukukhanya kufanele kube phansi ukuvimbela ukukhathala kwamehlo. Kodwa-ke, kumele futhi zigcine ukumpunga okuphezulu ukuqinisekisa i-gradient ebushelelezi kanye nokushintsha kombala. Ukuze uhlole lokhu, bheka isibonisi eduze bese uhlola noma yiziphi izimpawu zokubopha noma ukungahambisani kombala.
Ukunquma ikhwalithi ye-Isibonisi se-LEDkudinga ukuhlolwa okuphelele kwezici ezahlukahlukene, kusukela ekubeni yisicaba nokukhanya kuya ekukhiqizeni umbala kanye nokusetshenziswa kwamandla. Ngokuqonda lezi zici ezibalulekile, ungenza isinqumo esinolwazi lapho uthengaIsibonisi se-LEDukusetshenziswa komuntu siqu noma kobungcweti. Kungakhathaliseki ukuthi ufuna isibonisi sokukhangisa, ukuzijabulisa, noma esinye inhloso, ukukhumbula lezi zici kuzokusiza ukhethe isikrini se-LED sekhwalithi ephezulu esihlangabezana nezidingo zakho.
