Uchatshazelwe yi-Covid-19,Abavelisi besikrini esicacileyo be-LEDbanikela ingqalelo engakumbi kuphando kunye nophuhliso, ukwahlula amanqanaba esikrini esicacileyo, indibano, kunye neziphumo zemveliso yophawu. Imfazwe yexabiso elingabonakaliyo yenza kube nzima ukuba abavelisi beendibano baphile, kwaye abavelisi abanamandla bayakwazi ukugxila ekuphuhliseni iimveliso zesikrini ezicacileyo ze-LED kwiimarike zokuguquguquka kwexabiso kunye nokungafani, ngoko ke bemi ngaphandle.
Ngokunyuka kwemfuno yentengiso, itekhnoloji yesikrini esicacileyo se-LED kunye neemveliso ziphuculwa ngokuqhubekayo, kunye netekhnoloji esebenzisanayo iye yavela, izisa amava amahle. Ngokucuthwa ngokuqhubekayo kwepixel pitch kunye nokuphuculwa kokungena kunye nozinzo, izikrini ezicacileyo ze-LED ziye zahlala ngokuthe ngcembe kwimarike ngenkcazo ephezulu kunye neempawu ezicacileyo, kwaye zide zithathe indawo ebalulekileyo kwibala leendonga zeglasi.
Ngokukhula kokungafihli kwe-LED, izikrini zefilimu ze-LED, izikrini zeglasi, kunye nezikrini zefilimu zekristale ziye zaba ngumsebenzi obalaseleyo wokumela, kwaye izikrini ezicacileyo ezivulekileyo ezincinci ziye zaba yindlela entsha. Uphuhliso kunye nokusetyenziswa kwezi mveliso zesikrini ezicacileyo ziye zabona uphuhliso olukhawulezayo lwezikrini ezicacileyo.
Ngenxa yokuzaliswa ngokuthe ngcembe kwemarike yesikrini ye-LED eqhelekileyo kunye nokuthintelwa kokusetyenziswa kwayo kwimimandla efana neendonga zeglasi. Ukuphucula le meko, izikrini ezicacileyo ze-LED ziye zazalwa kwaye ziye zaphuhliswa ngokukhawuleza ukususela ngo-2017, ngokunyuka kokufumana inzuzo yemarike. Ngelo xesha, ekucwangcisweni kwedolophu kunye nokwakhiwa, izakhiwo zobunjineli zefestile zeglasi zithandwa kakhulu, eziye zakhokelela ekuveleni kwezikrini ezicacileyo ze-LED zangaphakathi. Ukunika izakhiwo zobunjineli beglasi ngefashoni, ukwahluka kombala, ubuxhakaxhaka banamhlanje, kunye nengqiqo yetekhnoloji, ukunika abantu imbonakalo eyodwa. Izikrini ezicacileyo ze-LED ziyaqhubeka nokugqabhuka, kunye namandla amakhulu okuthengisa. Ngokoqikelelo, ixabiso lentengiso yezikrini ezicacileyo ze-LED liya kuba malunga ne-10 yeebhiliyoni zeeyuan ngo-2025.
Kwiminyaka yakutshanje, ingcamango "yentengiso entsha" iye yavela, kwaye izikrini ezicacileyo ze-LED ziye zadlala indima ebalulekileyo kwiifestile zentengiso yokuthengisa, ukuhlobisa kwangaphakathi, i-facades yokwakha, kunye nezinye iindawo, ezizisa utshintsho olukhulu kwintengiso entsha. Umahluko kunye nengqiqo yethekhnoloji idala amava angcono okuthenga ngelixa ungaphazamisi uyilo lweefestile zokubonisa kunye neevenkile. Iimveliso ezininzi zefashoni, iimoto, ubucwebe kunye nezinye iimveliso ezikumgangatho ophezulu nazo zikhetha ukusebenzisa izikrini ezibonisa elubala ze-LED ukuphucula isitayile sophawu. Xa udlala umxholo wokuphromotha, imvelaphi ecacileyo ayinakunyusa kuphela ingqiqo yeteknoloji. Ukuvela kwentengiso entsha ngokuqinisekileyo kuya kuqhuba uphuhliso lwentengiso yokubonisa intengiso kunye nokudala imfuno ethile yezikrini ezicacileyo ze-LED.
Ngenxa yobume obucacileyo bezikrini ze-LED, ukucaca kwazo ngokuqinisekileyo kuchaphazeleka. Indlela yokufezekisa ukucaca okuphezulu ngaphandle kokuchaphazela ukungafihli ngumngeni wobugcisa ekufuneka woyiswe.
1. Indlela yokuphatha i-grayscale ebangelwa ukunciphisa ukukhanya kwe-LED izikrini ezicacileyo?
Xa usebenzisa isikrini se-LED esicacileyo njengesikrini sokubonisa i-LED yangaphakathi, ukukhanya kufuneka kuncitshiswe, ngaphandle koko, amehlo abantu akayi kukwazi ukuthwala ukubukela ixesha elide. Nangona kunjalo, njengoko ukukhanya kuncipha, umfanekiso uya kuba nelahleko enkulu yegreyscale. Njengoko ukukhanya kuncipha ngakumbi, ilahleko yegreyscale iba ngakumbi nangakumbi. Siyazi ukuba okukhona iphezulu inqanaba legreyscale, kokukhona ityebile imibala eboniswa kwiscreen esibonakalayo, kwaye kokukhona ubuthathaka kwaye ugcwele umfanekiso.
Isisombululo sokunciphisa ukuqaqamba kwezikrini ezicacileyo ze-LED ngaphandle kokuchaphazela i-grayscale: Ukukhanya komzimba wesikrini kukulungele ukugqama kokusingqongileyo kwaye kunokulungiswa ngokuzenzekelayo. Kuphephe ukuchaphazeleka kokugqama okugqithisileyo okanye okusingqongileyo okumnyama ukuqinisekisa umgangatho oqhelekileyo womfanekiso. Kwangaxeshanye, kusetyenziswa izikrini eziphezulu zegreyscale, kwaye inqanaba langoku legreyscale linokufikelela kwi-16bit.
2. Sombulula umonakalo obangelwa yi-LED yesikrini esicacileyo ukuphucula ukucaca
Ukuphakama kokucaca kwesikrini se-LED esicacileyo kunye neenkcukacha zomfanekiso, kokukhona amaso e-LED angaphezulu kwimodyuli enye aya kwanda kwaye asasazeke ngakumbi. Umgangatho oqhelekileyo wezinga lomonakalo wezibane zesikrini ze-LED kukulawula ngaphakathi kwe-3 / 10000, kodwa imodeli encinci ye-LED izikrini ezicacileyo, izinga lomonakalo wezibane ze-3 / 10000 azikwazi ukuhlangabezana neemfuno zokusetyenziswa kwansuku zonke. Umzekelo, imodeli ye-P3 yesikrini esicacileyo se-LED inamaso okukhanya angaphezu kwe-110000 ngemitha yesikwere. Ukucinga indawo yesikrini ye-4 square metres, inani lezibane ezonakalisiweyo ziya kuba yi-11 * 3 * 4 = 132, eya kuzisa amava okubukela okungenabubele kwisiboniso esiqhelekileyo sesikrini.
Umonakalo kwisibane ngokuqhelekileyo ubangelwa ukuthungwa okuxekethileyo kweentsimbi zesibane. Kwelinye icala, kungenxa yenkqubo yemveliso engalunganga yomenzi wesikrini ocacileyo we-LED, kwaye nangenxa yemiba yokuhlola umgangatho. Kakade ke, ingxaki yezibane zesibane ayinakukhutshelwa ngaphandle. Ngoko ke kuyimfuneko ukulandela inkqubo yokuhlola umgangatho osemthethweni ukulawula umgangatho wezinto eziluhlaza ngelixa ubeka iliso kwinkqubo yokuvelisa. Ngaphambi kokuba ushiye umzi-mveliso, kuyimfuneko ukwenza uvavanyo lweeyure ezingama-72 ukulungisa ingxaki kwizibane kwaye uqinisekise ukuba ziyimveliso efanelekileyo ngaphambi kokuthunyelwa.
3. Ukulungelelanisa okanye ukulungelelanisa?
Umba ophambili ngezikrini ezicacileyo ze-LED okwangoku kukwenza ngokwezifiso. Zininzi iimveliso ezilungiselelwe wena kwimarike, kwaye umjikelo wemveliso yeemveliso ezilungiselelweyo mde noko, kubandakanywa inkqubo yeR&D. Azikhawulezi njengeemveliso ezivuthiweyo ngoku kwaye kunzima ukuvelisa ngobuninzi. Ukongeza, njengoko kuyaziwa, amaso e-LED aphuma ecaleni asetyenziselwa ukuboniswa okucacileyo kwe-LED kwiimarike azikho jikelele, kunye nokungahambi kakuhle kunye nokuzinza, okubangelwa iindleko eziphezulu zemveliso, isivuno esiphantsi, kunye nenkonzo enzima emva kokuthengisa.
Kukho esinye isizathu esibalulekileyo ngoku sithintela uphuhliso lwezikrini ezicacileyo ze-LED - iindleko eziphezulu zokugcina. Phantse zonke iimveliso zesikrini ezicacileyo ze-LED zisetyenziselwa iiprojekthi ezinkulu zobunjineli, kwaye ubunzima bokugcinwa bubonakala. Ngoko ke, ukuveliswa okusemgangathweni kunye nokwakhiwa kwenkonzo yezikrini ezicacileyo ze-LED zifakwe kwi-ajenda kwaye ziphunyezwe ngamanye amafektri amakhulu. Kwixesha elizayo, iimveliso zesikrini ezikumgangatho ongaphezulu zinokungena kwiisayithi zesicelo ezingezizo ezodwa.
4. Imigqaliselo yokukhetha ukuqaqamba kwesikrini se-LED esicacileyo
Kwintsimi yogcino lwamandla kunye nokukhuselwa kwendalo, abavelisi besikrini be-LED abacacileyo baye baphucula kakhulu ukusetyenziswa kwamandla kwesikrini. Ngokusebenzisa ii-chips ezikhuphayo ze-LED ezinokukhanya okuphezulu okuphezulu kunye nokuqinisekisa ukuba akukho zimbombo zokusika okanye unikezelo lombane olusebenzayo, ukusebenza kakuhle kokuguqulwa kwamandla kuye kwaphuculwa kakhulu. Baye bamkela ukutshatyalaliswa kokushisa kwepaneli eyilwe kakuhle ukunciphisa ukusetyenziswa kwamandla e-fan, ukuyila ngokwesayensi isikimu sesekethe ngokubanzi, kunye nokunciphisa ukusetyenziswa kwamandla kwiisekethe zangaphakathi ngokweenguqu kwimeko yangaphandle, Ukukhanya kunokulungelelaniswa ngokuzenzekelayo ukufezekisa ukonga okungcono kwamandla.
Izinto ze-luminescent ezisetyenziselwa izikrini ezicacileyo ze-LED zinefuthe lokugcinwa kwamandla kunye nokusetyenziswa okuphantsi. Nangona kunjalo, ukuqwalasela isicelo sabo kwimiboniso eneendawo ezinkulu zokubonisa, ukuba zisetyenziswe ixesha elide, ukusetyenziswa kwamandla ngokubanzi kuya kuhlala kuphezulu, kwaye iindleko zombane ezithwalwa ngabakhangisi ziya kubonisa ukwanda kwejometri. Ke ngoko, indlela yokufezekisa ugcino lwamandla yingxaki ekufuneka iqwalaselwe ngabo bonke abavelisi besikrini esicacileyo se-LED.
