Emphakathini wanamuhla, izibonisi ze-LED zangaphandle seziphenduke amandla amakhulu okusabalalisa ulwazi kanye nesibonisi sokukhangisa. Kungakhathaliseki ukuthi kumabhulokhi ezentengiselwano, ezinkundleni zemidlalo noma ezigcawini zamadolobha, izibonisi ze-LED zekhwalithi ephezulu zinemiphumela yokubuka edonsa amehlo kanye nekhono elihle kakhulu lokudlulisa ulwazi. Ngakho-ke, yiziphi izici ezibalulekile okufanele sizicabangele lapho sikhetha isibonisi se-LED sangaphandle esingcono kakhulu? Lesi sihloko sizoxoxa ngokuningiliziwe ezicini ezimbalwa ezifana nokuphakama kwe-pixel, ikhwalithi ebonakalayo, ukuqina kwemvelo, ukusekelwa kwenkonzo egcwele, izinga lokuvikela kanye nokufakwa okulula.
1. Ukuphakama kwe-Pixel
1.1 Ukubaluleka kwePixel Pitch
Ukuphakama kwe-Pixel kubhekisela ebangeni elimaphakathi phakathi kwamaphikseli amabili ancikene kusibonisi se-LED, ngokuvamile ngamamilimitha. Ingenye yezinto ezibalulekile ezinquma ukulungiswa nokucaca kwesibonisi. Ukuphakama kwephikseli okuncane kunganikeza ukucaca okuphezulu nezithombe ezinhle, ngaleyo ndlela kuthuthukise ukuzizwisa okubonakalayo.
1.2 Ukukhetha kwePixel Pitch
Lapho ukhetha ukuphakama kwephikseli, ibanga lokufaka nebanga lokubuka lesibonisi lidinga ukucatshangelwa. Ngokuvamile, uma izethameli zibukele isibonisi kude, kunconywa ukuthi ukhethe ukuphakama kwephikseli encane ukuze kuqinisekiswe ukucaca nokucoleka kwesithombe. Isibonelo, ngebanga lokubuka lamamitha angu-5-10, iphikseli yephikseli yeP4noma encane ingakhethwa. Ezigcawini ezinebanga elide lokubuka, njengenkundla yezemidlalo enkulu noma isikwele sedolobha, ukuphakama kwephikseli okukhulu kakhulu, okufanaP10noma i-P16, ingakhethwa.
2. Ikhwalithi Ebonakalayo
2.1 Ukugqama Nokugqama
Ukukhanya nokugqama kwesibonisi se-LED sangaphandle kuthinta ngokuqondile ukubonakala kwaso ezindaweni zokukhanya okuqinile. Ukukhanya okuphezulu kuqinisekisa ukuthi isibonisi sihlala sibonakala ngokucacile phakathi nosuku nangaphansi kokukhanya kwelanga okuqondile, kuyilapho ukugqama okuphezulu kuthuthukisa isendlalelo nokuvezwa kombala kwesithombe. Ngokuvamile, ukukhanya kwesibonisi se-LED yangaphandle kufanele kufinyelele ama-nits angaphezu kuka-5,000 ukuze kuhlangatshezwane nezidingo zezindawo ezihlukahlukene.
2.2 Ukusebenza Kombala
Isibonisi sekhwalithi ephezulu ye-LED kufanele sibe ne-gamut yombala obanzi kanye nokukhiqizwa kombala ophezulu ukuze kuqinisekiswe ukuthi isithombe esibonisiwe siyagqama futhi singokoqobo. Lapho ukhetha, unganaka ikhwalithi yobuhlalu besibani se-LED kanye nokusebenza kwesistimu yokulawula ukuqinisekisa ukusebenza kombala okunembile.
2.3 I-engeli yokubuka
Idizayini ye-engeli yokubuka ebanzi iqinisekisa ukuthi isithombe sihlala sicacile futhi umbala uhlala unjalo lapho ubuka isibonisi ngama-engeli ahlukene. Lokhu kubaluleke kakhulu ezibukweni zangaphandle, ngoba izibukeli zivame ukuba nama-engeli ahlukahlukene wokubuka, futhi i-engeli yokubuka ebanzi ingathuthukisa umuzwa wokubuka usuwonke.
3. Ukuqina Kwemvelo
3.1 Ukumelana Nesimo Sezulu
Izikrini ze-LED zangaphandle zidinga ukubhekana nezimo zezulu ezinzima njengomoya, imvula, nelanga isikhathi eside, ngakho-ke zidinga ukumelana nesimo sezulu esihle kakhulu. Lapho ukhetha, kufanele unake izinkomba zokusebenza zesikrini esibonisiwe ezifana nokungangeni kwamanzi, ukuvikela uthuli, nokumelana ne-UV ukuze uqinisekise ukuthi singasebenza ngokuzinza ezindaweni ezihlukahlukene.
3.2 Ukuzivumelanisa nezimo
Isibonisi sidinga ukusebenza kahle endaweni yokushisa ephezulu nephansi, futhi ngokuvamile sinebanga lokushisa lokusebenza. Isibonelo, ukukhetha isibonisi esingasebenza ku--20°C kuya ku-+50°C kungaqinisekisa ukuthi singasebenza ngokuzinzile ngaphansi kwezimo zezulu ezimbi kakhulu.
4. Ukusekelwa Kwesevisi Yomjikelezo Wonke
4.1 Ukwesekwa Kwezobuchwepheshe
Ukukhetha umhlinzeki onosekelo oluphelele lobuchwepheshe kungaqinisekisa ukuthi ungathola usizo ngesikhathi lapho uhlangabezana nezinkinga phakathi nokusetshenziswa kwesibonisi. Ukwesekwa kobuchwepheshe okuhlanganisa ukufakwa nokulungisa iphutha, ukusebenza kwesistimu nokuxazulula inkinga yizici ezibalulekile zokuthuthukisa ulwazi lomsebenzisi.
4.2 Isevisi yangemuva kokuthengisa
Isevisi yekhwalithi ephezulu emva kokuthengisa ingaqinisekisa ukuthi isikrini sokubonisa singalungiswa futhi sishintshwe ngokushesha uma sehluleka. Ukukhetha umphakeli onesiqinisekiso sesikhathi eside sangemva kokuthengisa kunganciphisa izindleko zokunakekela kanye nezingozi zokusebenza ngesikhathi sokusetshenziswa.
5. Izinga Lokuvikela
5.1 Incazelo Yezinga Lokuvikela
Izinga lokuvikela livamise ukuvezwa ngekhodi ye-IP (Ingress Protection). Izinombolo zokuqala ezimbili zibonisa amandla okuvikela ezintweni eziqinile neziwuketshezi ngokulandelana kwazo. Isibonelo, izinga elijwayelekile lokuvikela lezibonisi ze-LED zangaphandle yi-IP65, okusho ukuthi alikwazi ukumelana nezintuli ngokuphelele futhi livimbela isifutho samanzi kuzo zonke izinhlangothi.
5.2 Ukukhethwa Kwezinga Lokuvikela
Khetha izinga elifanele lokuvikela ngokuya ngendawo yokufaka yesikrini esibonisiwe. Isibonelo, izibonisi zangaphandle ngokuvamile zidinga ukuthi okungenani zibe nesilinganiso sokuvikela se-IP65 ukuze zivikeleke emvuleni nasezintulini. Ezindaweni ezinesimo sezulu esibi kakhulu, ungakhetha izinga eliphezulu lokuvikela ukuze uthuthukise ukuqina kwesibonisi.
6. Kulula Ukufaka
6.1 Idizayini Engasindi
Idizayini yesibonisi engasindi ingenza inqubo yokufaka ibe lula futhi inciphise isikhathi sokufaka nezindleko zomsebenzi. Ngesikhathi esifanayo, kungase futhi kunciphise izidingo zokuthwala umthwalo esakhiweni sokufaka futhi kuthuthukise ukuguquguquka kokufakwa.
6.2 Idizayini ye-Modular
Isikrini sokubonisa samukela idizayini eyimojuli futhi singahlakazwa kalula, sihlanganiswe futhi sinakekelwe. Uma imojuli ilimele, ingxenye eyonakele kuphela edinga ukushintshwa esikhundleni sesibonisi sonke, esinganciphisa kakhulu izindleko zokunakekela kanye nesikhathi.
6.3 Izesekeli zokukhweza
Lapho ukhetha, naka izesekeli ezifakwayo ezinikezwa umphakeli, njengabakaki, amafreyimu nezixhumi, ukuze uqinisekise ukuthi zingezekhwalithi ethembekile futhi zingakwazi ukuzivumelanisa nezidingo zezindawo ezihlukene zokuzifaka.
Isiphetho
Ukukhetha isibonisi se-LED sangaphandle esingcono kakhulu kuwumsebenzi oyinkimbinkimbi odinga inhlanganisela yezinto, okuhlanganisa ukuphakama kwe-pixel, ikhwalithi ebonakalayo, ukuqina kwemvelo, usekelo lwesevisi ephelele, ileveli yokuvikela, nokufaka kalula. Ukuqonda okujulile kwalezi zici kungasisiza senze ukukhetha sinolwazi ukuze siqinisekise ukuthi isibonisi singanikeza ukusebenza okuhle kakhulu nokusebenza okuzinzile kwesikhathi eside ezindaweni ezihlukahlukene.
