Ungakwazi yini Ukwenza ngokwezifiso isikrini se-LED esisobala?

Yebo. Kodwa akulona iphuzu.

"Ukwenza ngendlela oyifisayo" embonini yesikrini se-LED esobala iyizwi lokumaketha. Vula noma iyiphi iwebhusayithi yomkhiqizi, futhi uzobona "ukwenza ngendlela oyifisayo kuyatholakala," "okuhambisana nezidingo zakho," "{1}}isevisi eyodwa yokumisa ngokwezifiso." Lokhu kudala inkohliso: njengokungathi noma yimuphi umumo, usayizi, noma umphumela ofisayo ungakhiqizwa.

U-90% walokho-okubizwa ngokuthi "ukwenza ngokwezifiso" ukuhlanganisa okujwayelekile{2}}kuhlanganisa nokufanisa.

Iyunithi eyisisekelo yesikrini se-LED esibonisa ngale iyimojuli-imvamisa izingcezu ezijwayelekile ezingu-500mm×500mm noma 1000mm×500mm. Isikrini esingu-3m×2m? Thatha amamojula angu-6 uwahlanganise. 5m×3m? Hlanganisa 15.

Ukwenza ngokwezifiso kwangempela{{0}osayizi{1}}abangewona{1}}amamojula ajwayelekile, ukusikeka okungajwayelekile, ama-curvature akhethekile{2}}abakhiqizi abaningi abafuni ukukwenza, noma bazocaphuna inani eliklanyelwe ukunqanda ukwamukelwa. Kungani? Ngoba "ukwenza ngokwezifiso" ekukhiqizeni kusho isikhunta esisha, ukulungiswa komugqa wokukhiqiza, ukuhlolwa kwekhwalithi ngakunye{4}}zonke izindleko. Futhi amamajini esikrini se-LED asobala asevele ayampintsha; abakhiqizi abanaso isisusa sokwamukela izidingo ezikhethekile.

Okushiwo "Ukwenza Ngokwezifiso" Empeleni (Ngakho Ukuthengisa Akukwazi Ukukukhohlisa)

Usayizi{{0}Ungenziwa ngendlela oyifisayo, kodwa kugridi

Osayizi besikrini ababonisa ngale bayinombolo ephelele yamasayizi amamojula. Ukucaciswa kwemojuli evamile: 500×500mm, 500×1000mm, 1000×500mm, 1000×1000mm. 3.5 amamitha ububanzi? Alikho{10}}kungenzeka lingamamitha angu-3 noma amamitha angu-4. 2.7 ubude? 2.5 amamitha noma amamitha angu-3{16}}khetha eyodwa.

Abanye abakhiqizi bangenza "amamojula wokusika" ukuze bathole-osayizi abangajwayelekile, kodwa lokhu kusho ama-PCB angokwezifiso, isikhunta esisha, esiqala ekukhuphukeni kwezindleko ngo-30-50%, kanye nesikhathi sokuhola esinde ngamaviki angu-2-4. Ukuthi kuyafaneleka yini kudinga ukubalwa.

I-Pixel Pitch-Inketho eyinhloko

P3.9, P7.8, P10, P15, P20... Le parameter inquma ngokuqondile ibhalansi phakathi kokucaca, ukungafihli, kanye nenani.

I-P3.9 isebenzela u-3-ukubuka kwamamitha angu-6, ikutholela obala okungu-55-65%, kubiza kakhulu. I-P7.8 ifanela amamitha angu-6-12, amabhampa okukhanya afika ku-65-75%, amanani entengo emaphakathi. I-P10 ingeyamamitha angu-10+ ukuphuma, 70-80% esobala, ithengeka kakhudlwana. I-P15 ne-P20? Lawo ngamabhodi ezikhangiso-ibanga lokubuka lamamitha ayi-15-30, ukubonakala obala okungu-75-85%, inketho eshibhe kakhulu.

Ukuphakama kwephikseli encane akuhlali kungcono-okungcono yilokho okufana nebanga lokubuka. Ama-atriums enxanxathela yezitolo, izindonga zamakhethini angaphandle, -iziboniso zamafasitela ezivala phezulu{3}}izimfuneko zihluke ngokuphelele.

Ukukhanya-Umehluko omkhulu phakathi kwangaphakathi nangaphandle

Ukusetshenziswa kwasendlini: 800-2000 nits kwanele. Ukukhanya kwelanga ngaphandle noma okuqondile: okungenani ama-nits angu-4000-6000, ngaphandle kwalokho akukho lutho oluzobonakala emini.

Ukukhanya kungenziwa ngendlela oyifisayo, kodwa ukukhanya okuphezulu kusho ukusetshenziswa kwamandla okukhulu, ukushisa okwengeziwe, intengo ephezulu. Buza umkhiqizi ukuthi ingabe ucaphuna "ukukhanya okuphezulu" noma "ukukhanya kokusebenza okuqhubekayo"{1}}abanye abakhiqizi bacaphuna amanani aphezulu angakwazi ukugcinwa ngesikhathi sokusetshenziswa okuqhubekayo.

Uyikhweza kanjani lento?

Ukulenga phezulu kusebenza kuma-mall atrium kanye nengemuva lesiteji. Inkundla-yokuma noma ukunqwabelanisa ifanele imibukiso yesikhashana. Ubuso-oboshiwe noma obushumekiwe{4}}onamathiselwe ngaphakathi kwezindonga zamakhethini engilazi{5}}uwuhlelo olusetshenziswa kakhulu lwezakhiwo. Ikholomu{7}efakwe ngosekelo lwabakaki abazimele isebenzela ukukhangisa kwangaphandle.

Indlela yokufaka inquma umumo wokulungisa amamojula (ukulungiswa kwangaphambili noma ukugcinwa kwangemuva), ukukhethwa kwezisekeli, ngisho nokwakheka kwesakhiwo samamojula ngokwawo. Lokhu kufanele kunqunywe ngaphambi koku-oda{1}}okungacaciswanga ngesikhathi sokufakwa.

Ukulungiswa kwangaphambili noma ngemuva? Yenza okungalungile futhi ubhidliza izindonga

Ukunakekela ingemuva kusho ukususa amamojula ngemuva. Idinga okungenani isikhala esingu-50cm ngemuva kwesikrini. Izindleko eziphansi. Ukulungiswa kwangaphambili kusho ukususa amamojula ngaphambili. Ifanele{5}ukufakwa odongeni{5}}okukhweziwe okungenasikhala ngemuva, ukwakheka kwemojuli eyinkimbinkimbi, izindleko eziphakeme ngo-10-20%.

Khetha indlela yokulungisa okungeyona, futhi lonke udonga lungase ludinge ukudilizwa ukuze kungene imojuli eyodwa.

Isistimu yokulawula-Gwema ukukhiya{1}}phakathi

Abakhiqizi abahloniphekile bazonikeza ukukhetha: ukusebenzisa isistimu yabo yokulawula ubunikazi, noma basebenzise-ezijwayelekile ezimbonini (NovaStar, Colorlight, Linsn).

Okunconyiwe: Khetha isistimu yendawo yonke. Amasistimu obunikazi angamaketanga. Ukuthuthukiswa nokugcinwa kwesikhathi esizayo kuyoba emseni wabo.

Isilinganiso Sokuvikela-Sincike esimweni

Indawo eyomile yasendlini: IP30-I-IP40 yanele. Umswakama wasendlini noma umhwamuko wamanzi: IP54. Ingxenye-ngaphandle noma ngaphandle ngokugcwele: IP65 noma ngaphezulu. Izinga ngalinye elikhuphukayo esilinganisweni sokuvikela lengeza u-5-15% enanini. Ungasebenzisi kakhulu unjiniyela, kodwa ungahloli futhi wenze isikrini sonakaliswe ngamanzi.

Imininingwane Yokubukeka-Iyalungiseka kodwa ilinganiselwe

Umbala wozimele (omnyama/omhlophe/osilver/ompunga), umbala womugqa we-LED, indawo yebhokisi lamandla-abakhiqizi abaningi bangakwazi ukukwamukela lokhu.

Kodwa okulindelekile kufanele kube nomkhawulo: Imibala ye-chip ye-LED, ububanzi be-strip, ukujiya kwemojuli-lokhu kumisiwe. Ngaphandle kwalapho ivolumu inkulu ngokwanele ukuthethelela umugqa wokukhiqiza ozinikele, akukho okuwushintshayo.

Ngakho-okuthiwa "ukwenza ngokwezifiso" kungu-80% mayelana nokwenza izinhlanganisela ngaphakathi kwezinketho ezingaguquki. Thola ukuphakama kwephikseli, ukukhanya, usayizi, indlela yokufaka, indlela yokulungisa, isistimu yokulawula, kanye nesilinganiso sokuvikela kwesokudla{3}}isikrini senziwe ngendlela{4}}senziwe. Kwenze kube okungalungile, futhi akukho mali echithwa "kumumo okhethekile" ozoyilondoloza. Ama-20% asele? Kubiza kakhulu noma akwamukelekile.

I-Transparency Scam

Iphoyinti lokuthengisa eliyinhloko lezikrini ze-LED ezibonisa ngale "ukubonisa ngale." Kodwa ukulebula obala kwale mboni kuyinhlakanhlaka.

Uma umenzi ethi 80% obala, bayithole kanjani leyo nombolo? Abanye bakala isilinganiso sezikhala phakathi kwemichilo ye-LED ukuya endaweni ephelele-lokho ukukhanya kwejiyomethri. Okunye kukala ukudluliswa kokukhanya kwangempela{3}}lokho ukukhanya kokubona. Ezinye azibandakanyi uhlaka, ukunikezwa kwamandla, namakhebuli ngokuphelele, kukala kuphela indawo ekhanye kakhulu. Abanye baze bacaphune "ukubonisa ngale kwethiyori" umkhiqizo wangempela ongakwazi ukukufeza. Alikho izinga elihlanganisiwe{7}}izinombolo ziyinoma yini enqunywa umkhiqizi.

Ukukhanya okuphezulu kusho imichilo ye-LED emincane, isikhala esikhulu, ama-LED chips ambalwa. Ama-chips e-LED ambalwa asho ukukhanya okuphansi, amaphikseli amancane. Yima amamitha angu-3 ukusuka esikrinini se-P10 esinokubonisa ngale okungu-85%, futhi isithombe sihlakazekile-amaphikseli abonakala ngokucacile. Akusona "isikrini" kodwa imigqa yamachashazi akhazimulayo.

Ngakho-ke uma umkhiqizi eziqhayisa ngokuthi "u-90% osobala," imibuzo okufanele uyibuze ithi: yini ukuminyana kwephikseli? Kuyini ukukhanya kwangempela? Iliphi ibanga lokubuka? Uma lokhu kungacaciswanga, ukuzisola kulandela ngemuva kokusayina inkontileka.

Ukwehluleka okuningi kwephrojekthi kusuka kulokhu: iklayenti lihlatshwe umxhwele "ukukhanya okuphezulu," kodwa ngemuva kokufakwa kuthole ukuthi okuqukethwe bekungabonakali phakathi nosuku futhi kukhanye kakhulu ebusuku. Okusobala, yebo{1}}kodwa ingxenye yokusebenza kwesikrini yonakalisiwe.

Khohlwa "ukwenza ngokwezifiso"-Qala ngebanga lokubuka

Kunokuba ukhathazeke ngokuthi "ingenziwa ngendlela oyifisayo," thola into eyodwa: liyini ibanga lokuyibuka? Lokhu kunquma ukuphakama kwephikseli. I-Pixel pitch inquma izindleko, obala, ikhwalithi yokubonisa{1}}inquma cishe yonke into.

Isibalo silula: Ibanga elincane lokubuka (amamitha) ≈ Pixel pitch (amamilimitha)

Isikrini se-P3.9 sisebenza kahle ekubukeni phakathi kwamamitha angu-4. Isikrini se-P10 sihlangana kuphela ukusuka kumamitha angu-10+ kude. Isikrini se-P20 senzelwe izibukeli eziqhele ngamamitha amaningi. Khetha ukuphakama kwephikseli okungalungile, futhi akukho mali ezoyigcina.

Nansi into engiyibone kaninginingi: amafasitela ezitolo anezikrini ezisobala ze-P10 noma ze-P16, abanikazi bekhala ngemiphumela engemihle. Ibanga lokubuka iwindi lingamamitha angu-2-3-i-P10 enamaphikseli amakhulu kunesithupha esifakiwe, futhi kulindeleke ukuthi libukeke kahle? Kodwa i-P10 iyimali egcinwe eshibhile, yonakalise umphumela.

Incazelo yangempela yokuthi "ukwenza ngendlela oyifisayo" ukungabi nomkhiqizi akhe isikrini esingavamile-esimise ngendlela eyinqaba{1}}ukuthola iphoyinti lebhalansi phakathi kokuphakama kwephikseli, ukukhanya, ukukhanya, nesabelomali esifanelana kangcono nesimo. Lokhu kudinga ukwahlulela kochwepheshe, hhayi ukugcwalisa ifomu lezidingo kanye nokulinda izingcaphuno.

Izikrini Ezigobile Zibukeka Zimangalisa Emibukisweni Yezohwebo. Kumaphrojekthi Angempela, Ayiphupho Elibi.

Igobile, i-cylindrical, igagasi-elimise okwesiyingi{1}}lezi izinto eziheha kakhulu-emibukisweni, futhi lokho abakhiqizi abathanda ukukubonisa "njengamakhono abo okwenza ngokwezifiso."

Kodwa kumaphrojekthi wangempela, izikrini ezingajwayelekile zinezingibe eziningi kunezikrini eziyisicaba.

Izindleko azikhuphuki ngokulandelana{0}zikhuphuka kakhulu. Isikrini esigobile sendawo efanayo singabiza izikhathi ezingu-2-3 njenge-flatscreen ngoba sidinga ama-PCB aguquguqukayo noma ukuhlanganiswa kwemojuli yosayizi abancane, namazinga esivuno aphansi nezinqubo eziyinkimbinkimbi.

I-Curvature inemikhawulo yomzimba. Umkhiqizi angase athi "singenza ijika," kodwa ingakanani irediyasi yokugoba? Umkhawulo wemikhiqizo ejwayelekile uzungeze u-500-1000mm. Ufuna ijika eliqinile? Ama-chips e-LED azowa, ama-PCB azoqhekeka.

Kukhona enye inkinga abantu abaningi abangayicabangi: ama-seams akhuliswa ezindaweni ezigobile. Imithungo yemojuli ezikrinini eziyisicaba ingalawulwa ukuze icishe ingabonakali ngeso lenyama. Kodwa ezindaweni ezigobile, amamojula ahlangana ngama-engeli, okwenza imithungo ibonakale-ikakhulukazi ezigcawini ezimnyama, lapho kuvela khona imigqa emnyama ebonakalayo.

Bese kuba khona isondlo. Uma imojuli yehluleka esikrinini esiyisicaba, yisuse, uyishintshe{1}kuthatha amaminithi. Amamojula wesikrini agobile enziwa ngama-engeli angokwezifiso. Ukushintsha eyodwa kungase kusho ukulinda umenzi ukuthi ayikhiqize futhi. Kuthiwani uma iyekwa?

Izikrini ezingajwayelekile zingenziwa. Kodwa ngaphandle uma isimo sidinga ngempela isimo esingajwayelekile somphumela, izikrini eziyisicaba ziyathandeka. Ishibhile, izinzile, kulula ukuyinakekela.

Lapho Imali Iya Khona Empeleni (Futhi Lapho Umakwa Khona)

Ukuqonda ukwakheka kwenzuzo yale mboni kuveza ukuthi imakethe ikuphi kumakhwothi.

Ingxenye enkulu yezindleko zezikrini ze-LED ezibonisa ngale i-chip ye-LED, ebalwa u-30-40% wesamba sezindleko. Abakhiqizi be-chip (i-Sanan, i-Changelight, i-Epistar) bakhuphuka nomfula, banemali eshibhile engu-15-25% -lezi zintengo zibonakala ngale.

Ukupakisha-ukuguqula ama-chips abe ubuhlalu be-LED{1}kubangela u-15-20%. Izinkampani ezifana neNationstar ne-MLS ziphethe lokhu, ngamanani aphelele ka-10-20%.

Lapho amamajini ephakeme kakhulu kusekukhiqizweni kwesikrini nokuhlanganiswa kwesistimu-amamajini aphelele angu-20-40%. Lapha futhi yilapho umaka obuningi ukhona.

Ikhwothi etholiwe kungenzeka idlule kwizendlalelo ezingu-2-3 ukusuka kumkhiqizi ukuya kumsebenzisi wokugcina: umkhiqizi → umsabalalisi wesifunda → isihlanganisi → umsebenzisi wokugcina. Isendlalelo ngasinye sengeza u-10-30%. Umkhiqizo ofanayo ngamashaneli ahlukene ungahluka ngamanani angama-50%.

Kukhona nephuzu lenzuzo elifihliwe: uhlelo lokulawula. Abakhiqizi abaningi basebenzisa amaphrothokholi obunikazi{1}uma isikrini sabo sesisetshenzisiwe, amakhadi abo okulawula, isofthiwe yabo, ukusekela kwabo kobuchwepheshe kufanele kusetshenziswe. Ukunakekelwa okulandelayo, ukuthuthukiswa{3}}noma ngabe iyiphi intengo abayishoyo, akukho ukukhetha.

Indlela yokugwema izingibe? Zama ukuthola umthombo ngokuqondile kubakhi besikrini, weqa abaxhumanisi. Gxila kumasistimu okulawula jikelele (i-NovaStar, i-Colourlight izindinganiso zomkhakha)-ungavaleleka kumasistimu obunikazi. Qhathanisa okungenani izingcaphuno ezintathu-uma kunokuhlukahluka kwentengo okubalulekile kokucaciswa okufanayo, okuthile kudinga uphenyo.

Isikrini Siwuhhafu Wezindleko Kuphela. Ngokujulile.

Esikrinini se-LED esibonisa ngale, umkhiqizo ngokwawo ungabala kuphela u-50-60% wesamba semali etshaliwe. Ngabe abanye bayaphi?

Ukufakwa kanye nezinhlelo ezisekelayo.

Izikrini ezibonisa ngale zibukeka zilula futhi zizacile, kodwa azilula-8-15 kg imitha yesikwele ngayinye. Udonga lwekhethini lengilazi eliyisikwele esingamamitha angu-100 elinezikrini ezibonisa ngale kwengeza cishe ithani lomthwalo owengeziwe. Ingabe udonga lwamakhethini olukhona lungakwazi ukuluphatha? Ingabe idinga ukuqiniswa? Lokhu akuwona umthwalo womkhiqizi - badinga ukuhlolwa konjiniyela besakhiwo.

Olunye udaba lukagesi. Izikrini ezibonisa ngale zisebenzisa ama-watts angu-200-600 ngemitha yesikwele ngayinye. Ku-100 square metres, lokho kungu-20-60 kilowatts. Ingabe uhlelo lokusabalalisa ugesi lwanele? Ingabe izintambo zikagesi ezizinikezele ziyadingeka?

Kuthiwani ngokukhipha ukushisa? Ama-LED akhiqiza ukushisa, futhi izindonga zamakhethini ezingilazi aziphefumuli. Isikhala phakathi kwesikrini nengilazi siyashisa kakhulu, ikakhulukazi kuma-facade-abheke eningizimu ehlobo. Ngaphandle kokubhekana nokukhishwa kokushisa, ubude besikhathi besikrini buba sengozini kakhulu.

Ukuxhumana kwezokwakha nakho kuyinkinga. Emabhilidini amasha, izikrini ezibonakalayo zidinga ukuhlanganiswa nomklamo wodonga lwamakhethini kusengaphambili. Kumaphrojekthi okulungisa, umsebenzi we-facade wangaphandle ungase udinge ukugunyazwa. Izakhiwo zezentengiselwano nazo zidinga ukucabangela ukuthi ukwakhiwa kuthinta kanjani ukusebenza kwebhizinisi.

Lokhu "ukwenza ngendlela oyifisayo"-okuyiqiniso hhayi ukwenza ngokwezifiso isikrini, kodwa ukwenza ngokwezifiso isisombululo esiphelele. Abakhiqizi noma abahlanganisi abacabangela konke lokhu yilabo abanekhono langempela lokuletha. Labo abakhuluma ngezikrini kuphela ngaphandle kokuxoxa ngokufakwa balindele ukukhokhiswa okwengeziwe ngokuhamba kwesikhathi noma bahlela ukunyamalala ngemva kokulethwa.

Umugqa Ophansi

Igama elithi "ukwenza ngokwezifiso" lenza izikrini ze-LED ezibonisa ngale zibonakale zingamandla onke. Kodwa empeleni, lona umkhiqizo wezimboni ovuthiwe onemingcele ecacile yezobuchwepheshe nezimiso zezomnotho.

Lokho abakhiqizi abangakwenza ukusiza ukuthola ukucushwa okufanele ngaphakathi kwezinhlaka zobuchwepheshe ezimisiwe. Lokho abakhiqizi abangakwazi ukukwenza ukwephula imithetho ye-physics.

Esikhundleni sokubuza ukuthi "ingabe ingenziwa ngendlela oyifisayo," buza "yini ngempela edingekayo?" Thola ibanga lokubuka, ukukhanya kwe-ambient, izimo zokufakwa, nemikhawulo yebhajethi. Uma lezi zingqinamba sezichaziwe, isixazululo esilungile siyavela ngokwemvelo. Okunye ukuthola nje umenzi onokwethenjelwa ukuze akwenzele.
