Ngaba ungenza ngokwezifiso isikrini se-LED esicacileyo?

Ewe. Kodwa ayisiyiyo loo nto.

"Ukwenza ngokwezifiso" kwimboniselo yesikrini se-LED ecacileyo ligama lokuthengisa. Vula nayiphi na iwebhusayithi yomenzi, kwaye uya kubona "ukwenza ngokwezifiso kufumaneka," "okulungelelaniswe neemfuno zakho," "{1}}inkonzo yokumisa enye." Oku kudala inkohliso: ngokungathi nayiphi na imilo, ubungakanani, okanye isiphumo esinqwenelekayo sinokuveliswa.

I-90% yento-ebizwa ngokuba "ukwenza ngokwezifiso" yindibano nje yemodyuli{2}}xuba kwaye udibanise.

Iyunithi esisiseko yesikrini se-LED esicacileyo yimodyuli-ngokuqhelekileyo amaqhekeza asemgangathweni angama-500mm×500mm okanye 1000mm×500mm. Isikrini se-3m×2m? Thatha iimodyuli ezi-6 kwaye uzidibanise. 5m×3m? Iqhekeza kunye ne-15.

Ukwenza ngokwenyani{0}okungekho{1}}ubungakanani bemodyuli eqhelekileyo, ukusikwa ngokungaqhelekanga, iigophe ezikhethekileyo{2}}uninzi lwabavelisi abafuni kukwenza, okanye bayakucaphula ixabiso eliyilelwe ukutyhafisa ukwamkelwa. Ngoba? Kuba "ukwenza ngokwezifiso" kwimveliso kuthetha ukubumba okutsha, uhlengahlengiso lomgca wemveliso, ukuhlolwa komgangatho ngamnye{4}}zonke iindleko. Kwaye imida yesikrini ye-LED ecacileyo sele icinezelwe; abavelisi abanayo inkuthazo yokuhlangabezana neemfuno ezizodwa.

Oko kuthetha ukuthini "ukwenza ngokwezifiso" (Ngoko ke ukuthengisa akunakwenza bullshit kuwe)

Ubungakanani-Okwenziweyo, kodwa kwigridi

Ubungakanani beskrini obungafihliyo ziziphindaphindo ezipheleleyo zobukhulu bemodyuli. Iinkcukacha zemodyuli eziqhelekileyo: 500×500mm, 500×1000mm, 1000×500mm, 1000×1000mm{9}} ububanzi beemitha? Ayikho{10}}inokuba yi-3 yeemitha okanye i-4 yeemitha{13}} ubude? 2.5 yeemitha okanye 3 yeemitha{16}chola ibe nye.

Abanye abavelisi banokwenza "iimodyuli zokusika" ukufikelela -ubungakanani obuqhelekileyo, kodwa oku kuthetha ukuba iiPCB zesiko, iimodyuli ezintsha, ukuqala kwi-30-50% ukunyuka kweendleko, kunye neveki ezi-2-4 ixesha elide lokukhokela. Ukuba kufanelekile kufuna ukubala.

Pixel Pitch{0}Olona khetho lungundoqo

P3.9, P7.8, P10, P15, P20... Le parameter imisela ngokuthe ngqo ibhalansi phakathi kokucaca, ukungafihli kunye nexabiso.

I-P3.9 isebenza kwi-3-i-6 yokujonga imitha, ikufumana 55-65% elubala, ixabisa kakhulu. I-P7.8 ifanele i-6-12 yeemitha, i-transparency bumps ukuya kwi-65-75%, amaxabiso aphakathi. I-P10 yeye 10+ yeemitha ngaphandle, 70-80% ecacileyo, efikelelekayo. I-P15 kunye ne-P20? Ezo zezebhodi-iibhodi-15-30 umgama wokubukela, 75-85% elubala, ukhetho olusezantsi.

Inowuthi yepixel encinci ayisoloko ingcono{0}}into engcono kukuhambelana nomgama wokujonga. Iiatriums zokuthenga, iindonga zekhethini zangaphandle, vala{2}}imiboniso yefestile{3}}iimfuno zahluke ngokupheleleyo.

Ukukhanya{0}}Umahluko omkhulu phakathi kwangaphakathi nangaphandle

Ukusetyenziswa kwangaphakathi: 800-2000 ii-nits zanele. Ukukhanya kwelanga ngaphandle okanye ngokuthe ngqo: ubuncinci be-4000-6000 nits, ngaphandle koko akukho nto iya kubonakala emini.

Ukukhanya kunokwenziwa ngokwezifiso, kodwa ukukhanya okuphezulu kuthetha ukusetyenziswa kwamandla amakhulu, ubushushu obuninzi, ixabiso eliphezulu. Buza umvelisi ukuba bacaphula "ukukhanya okuphezulu" okanye "ukukhanya okusebenzayo okuqhubekayo"{1}}abanye abavelisi bacaphula amaxabiso aphezulu angenakugcinwa ngexesha lokusetyenziswa okuqhubekayo.

Uyixhoma njani le nto?

Ukuxhoma phezulu kusebenza kwiiatriums zemall kunye neqonga elingasemva. Umhlaba -omileyo okanye wokupakisha ulungele imiboniso yethutyana. Umphezulu{{3}oxhonyiweyo okanye ohlonyelweyo{4}}oncanyathiselwe ngaphakathi kweendonga zeglasi yomkhusane-yeyona nkqubo ixhaphakileyo yolwakhiwo. Ikholamu-ixhonywe ngenkxaso yesibiyeli ezimeleyo isebenza kwintengiso yangaphandle.

Indlela yokufakela imisela ukuqhelaniswa nokugcinwa kwemodyuli (ukugcinwa kwangaphambili okanye ukugcinwa kwangasemva), ukhetho lwezixhobo, kunye noyilo lwesakhiwo seemodyuli ngokwazo. Oku kufuneka kugqitywe phambi koku-odola{1}}akuchazwanga ngexesha lofakelo.

Ukugcinwa kwangaphambili okanye ngasemva? Yenza oku kungalunganga kwaye udiliza iindonga

Ukugcinwa kwangasemva kuthetha ukususa iimodyuli ngasemva. Ifuna ubuncinci isithuba se-50cm emva kwesikrini. Iindleko eziphantsi. Ukugcinwa kwangaphambili kuthetha ukususa iimodyuli ukusuka ngaphambili. Ifanelekile eludongeni -ufakelo olunyusiweyo olungenandawo ngasemva, ubume bemodyuli entsonkothileyo, 10-20% ixabiso eliphezulu.

Khetha indlela yokulungisa engalunganga, kwaye udonga luphela lunokufuna ukudilizwa ukuze kubuyiselwe imodyuli enye.

Inkqubo Yokulawula{0}}Kuphephe ukutshixa{1}}ngaphakathi

Abavelisi abahloniphekileyo baya kunika ukhetho: basebenzise inkqubo yabo yolawulo lobunini, okanye basebenzise imboni{0}}esemgangathweni (NovaStar, Colorlight, Linsn).

Ingcebiso: Khetha inkqubo yehlabathi jikelele. Iinkqubo zobunini ngamakhamandela. Uphuculo lwexesha elizayo kunye nokugcinwa kuya kuba kwinceba yabo.

Ukukala koKhuseleko{0}}Kuxhomekeke kwimeko

Indawo eyomileyo yangaphakathi: IP30-I-IP40 yanele. Ukufuma kwangaphakathi okanye umphunga wamanzi: IP54. Isiqingatha -ngaphandle okanye ngaphandle ngokupheleleyo: IP65 okanye ngaphezulu. Inqanaba ngalinye phezulu kwinqanaba lokukhusela longeza i-5-15% kwixabiso. Musa ukwenza injineli ngaphezulu, kodwa ungajongeli phantsi kwaye isikrini sonakaliswe ngamanzi.

Iinkcukacha ngenkangeleko{0}}Inohlengahlengiswa kodwa ilinganiselwe

Umbala wesakhelo (omnyama/omhlophe/isilivere/ngwevu), umbala womgca we-LED, indawo yebhokisi yamandla-uninzi lwabavelisi banokuthatha ezi.

Kodwa okulindelekileyo kufuneka kuncitshiswe: Imibala yetshiphu ye-LED, ububanzi bestrip, ubukhulu bemodyuli-ezi zisemgangathweni. Ngaphandle kokuba umthamo mkhulu ngokwaneleyo ukuthethelela umgca wemveliso ozinikeleyo, akukho tshintsho kubo.

Ke -ebizwa ngokuba "ukwenza ngokwezifiso" yi 80% malunga nokwenza indibaniselwano phakathi kokhetho oluzinzileyo. Fumana inowuthi yepixel, ukuqaqamba, ubungakanani, indlela yokuhlohla, indlela yokulondoloza, inkqubo yolawulo, kunye nokhuseleko loreyithiso oluchanekileyo{3}}isikrini senziwe{4}}senziwe. Zifumane zingalunganga, kwaye akukho mali echithwe "kwimilo ekhethekileyo" iya kuyigcina. I-20% eseleyo? Ixabisa ngokugqithisileyo okanye ayimkelwanga.

Ubuqhophololo bokuNgafihli

Inqaku eliphambili lokuthengisa izikrini ze-LED ezicacileyo "kukungafihli." Kodwa ukuleyibhelishwa kwezinto elubala kolu shishino kubugqwirha.

Xa umenzi esithi 80% elubala, balifumana njani elo nani? Abanye balinganisa umlinganiselo wezikhewu phakathi kwemicwe ye-LED ukuya kwindawo iyonke{1}}leyo yijiyometri transparency. Abanye balinganisa ukuhanjiswa kokukhanya okukokwenyani-kukukhanya okubonakalayo. Ezinye azibandakanyi isakhelo, unikezelo lwamandla, kunye neentambo ngokupheleleyo, zilinganisa kuphela eyona ndawo ingafihliyo. Abanye bade bacaphule "ithiyori elubala" ukuba eyona mveliso ayinakuyifumana. Akukho mgangatho umanyeneyo{7}}amanani ayo nantoni na ethathwa ngumenzi.

Ukucaca okuphezulu kuthetha imicu ye-LED emincinci, izithuba ezinkulu, iichips ze-LED ezimbalwa. Iichips ze-LED ezimbalwa zithetha ukuqaqamba okuphantsi, iipikseli ezinqabileyo. Yima kumgama oziimitha ezi-3 ukusuka kwisikrini se-P10 kunye ne-85% elubala, kwaye umfanekiso usasaziwe-iipixels zibonakala ngokucacileyo. Ayisiyo "screen" kodwa iirowu zamachaphaza abengezelayo.

Ke xa umenzi eqhayisa "ngama-90% elubala," imibuzo omawuyibuze yile: yintoni ingxinano yepixel? Kokuphi kanye ukuqaqamba? Ngowuphi umgama wokujonga? Ukuba ezi azikacaciswa, ukuzisola kulandela emva kokusayina isivumelwano.

Iintsilelo ezininzi zeeprojekthi zivela kule nto kanye: umxhasi wachukunyiswa "kukukhanya okuphezulu," kodwa emva kokufakwa kwafumanisa umxholo wawungabonakali emini kwaye ubengezela kakhulu ebusuku. Okusekuhleni, ewe{1}}kodwa isiqingatha sokusebenza kwesikrini sonakalisiwe.

Libala "ukwenza ngokwezifiso"-Qala ngokuJonga umgama

Kunokuba ujonge "ingaba inokwenziwa ngokwezifiso," fumana into enye: uthini umgama wokubukela? Oku kugqiba ukunyuswa kwepixel. Ukuphakama kwePixel kumisela ixabiso, ukungafihli, umgangatho wokubonisa{1}}imisela phantse yonke into.

Ubalo lulula: Ubuncinane bomgama wokujonga (iimitha) ≈ Pixel pitch (imilimitha)

Isikrini se-P3.9 sisebenza kakuhle xa sijongwa ngaphakathi kweemitha ezi-4. Isikrini se-P10 sidibana kuphela ukusuka kwi- 10+ yeemitha kude. Isikrini se-P20 senzelwe ababukeli kude nemitha emininzi. Khetha i-pixel pitch engalunganga, kwaye akukho mali iya kuyigcina.

Nantsi into endiyibonileyo ngokuphindaphindiweyo: iifestile zemall zibonisa nge-P10 okanye i-P16 izikrini ezicacileyo, abanini bekhalaza ngeziphumo ezibi. Umgama wokujonga ifestile yi-2 nje-3 yeemitha{7}}i-P10 eneepixels ezinkulu kunobhontsi ofakiweyo, kwaye kulindeleke ukuba ibukeke ilungile? Kodwa i-P10 yimali egcinwe ngexabiso eliphantsi, yonakalise isiphumo.

Intsingiselo yokwenyani "yokwenza ngokwezifiso" ayikukuba umenzi wakhe ongaqhelekanga-isikrini esimile{1}}kukufumana indawo elungeleleneyo phakathi kwepixel inowuthi, ukungafihli, ukuqaqamba, kunye nohlahlo lwabiwo-mali oluyifaneleyo imeko. Oku kufuna isigwebo esichubekileyo, singagcwalisi ifom yeemfuno kunye nokulinda iikowuti.

Izikrini ezigobileyo zijongeka ziyamangalisa kwiMiboniso yoRhwebo. KwiiProjekthi zokwenyani, ziyiphupha elibi.

Igophe, icylindrical, iliza -elimile, singqukuva{1}}ezi zezona zinto zitsala amehlo{2}}kumboniso, kwaye yintoni abavelisi abathanda ukuyibonisa "njengesakhono sabo sokwenza."

Kodwa kwiiprojekthi zokwenyani, izikrini ezingaqhelekanga zinemigibe emininzi kunezikrini ezicaba.

Iindleko azinyuki ngokulandelelana{0}zonyuka kakhulu. Isikrini esigobileyo saloo ndawo sinokuxabisa i-2-i-3 amaxesha amaninzi njengeskrini esicaba kuba sifuna ii-PCB eziguquguqukayo okanye i-module yemodyuli encinci, kunye nemilinganiselo ephantsi yesivuno kunye neenkqubo ezinzima.

I-Curvature inemida yomzimba. Umenzi unokuthi "singenza igophe," kodwa yeyiphi iradiyasi egobayo encinci? Umda weemveliso eziqhelekileyo ujikeleze i-500-1000mm. Ngaba ufuna igophe elingqongqo? Iichips ze-LED ziya kuwa, iiPCB ziya kuqhekeka.

Kukho omnye umba abantu abaninzi abangawuthatheli ngqalelo: i-seams yenziwe yandiswa kwindawo egobileyo. Imithungo yeemodyuli kwizikrini ezisicaba zinokulawulwa ukuba ziphantse zingabonakali kwiliso lenyama. Kodwa kwimigangatho egobileyo, iimodyuli zidibana kwii-engile, zenza imithungo icace-ingakumbi kwimiboniso emnyama, apho kuvela imigca emnyama ebonakalayo.

Kwaye ke kukho isondlo. Xa imodyuli isilele kwiscreen esisicaba, yisuse, yibuyisele kwakhona{1}}kuthatha imizuzu. Iimodyuli zesikrini ezigobileyo zenziwe kwii-engile eziqhelekileyo. Ukutshintsha enye kusenokuthetha ukulinda ukuba umenzi aphinde ayivelise kwakhona. Kuthekani ukuba iyekwa?

Izikrini ezingaqhelekanga zingenziwa. Kodwa ngaphandle kokuba imeko ifuna ngokwenyani imilo engaqhelekanga yesiphumo, izikrini ezicaba zikhethwayo. Ixabiso eliphantsi, elizinzileyo, kulula ukuyigcina.

Apho imali ingena khona ngokwenene (kwaye apho uphawulelwa khona)

Ukuqonda ulwakhiwo lwenzuzo yolu shishino lubonisa apho uphawulo lukhoyo kwiikowuti.

Elona candelo likhulu lexabiso lezikrini ze-LED ezicacileyo yi-chip ye-LED, ibalwa kwi-30-40% yeendleko zizonke. Abavelisi be-Chip (i-Sanan, i-Changelight, i-Epistar) iphezulu, kunye nemida ye-gross ye-15-25% -la maxabiso abonakali ngokucacileyo.

Ukupakishwa-ukujika iitshiphusi zibe ngamaso e-LED{1}i-akhawunti ye-15-20%. Iinkampani ezifana neNationtar kunye ne-MLS zijongana nale nto, kunye nemida ye-gross ye-10-20%.

Apho imida iphezulu kukwenziwa kwesikrini kunye nodibaniso lwenkqubo -imida yegross yama-20-40%. Apha kukwalapho olona phawu lukhoyo lukhona.

Isicatshulwa esifunyenweyo sinokuthi sidlule kwi-2-3 umaleko ukusuka kumvelisi ukuya kumsebenzisi wokugqibela: umenzi → umsasazi wengingqi → isihlanganisi → umsebenzisi wokugqibela. Umaleko ngamnye wongeza i-10-30%. Imveliso efanayo ngokusebenzisa amajelo ahlukeneyo inokuhluka nge-50% ngexabiso.

Kukho kwakhona indawo efihliweyo yenzuzo: inkqubo yokulawula. Abavelisi abaninzi basebenzisa iiprothokholi zobunikazi{1}emva kokuba isikrini sabo sisetyenzisiwe, amakhadi abo olawulo, isoftware yabo, inkxaso yabo yobugcisa kufuneka isetyenziswe. Ulondolozo olulandelayo, uphuculo{3}loluphi na ixabiso abacaphula ngalo, akukho ukukhetha.

Indlela yokuphepha imigibe? Zama ukukhangela ngqo kubavelisi besikrini, utsiba abalamli. Gxininisa kwiinkqubo zolawulo jikelele (i-NovaStar, i-Colourlight yimigangatho yoshishino){1}}ungatshixelwa kwiinkqubo zobunini. Thelekisa ubuncinci izicaphulo ezithathu{3}}ukuba kukho ukwahluka kwexabiso okubalulekileyo kwingcaciso efanayo, kukho into efuna uphando.

Isikrini sisiqingatha seendleko kuphela. Ngokunyanisekileyo.

Kwisikrini se-LED esicacileyo, imveliso ngokwayo ingaba ne-akhawunti ye-50-60% yotyalo-mali lulonke. Ziyaphi ezinye?

Ufakelo kunye neenkqubo ezixhasayo.

Izikrini ezicacileyo zikhangeleka zikhaphukhaphu kwaye zibhityile, kodwa azikhaphukhaphu-8-15 kg kwisikwere semitha. Udonga lomkhusane weglasi ye-100-square-square enezikrini ezicacileyo zongeza phantse itoni yomthwalo owongezelelweyo. Ngaba ulwakhiwo olukhoyo lodonga lomkhusane luyakwazi ukuyiphatha? Ngaba ifuna ukuqiniswa? Olu ayiloxanduva lomenzi-bafuna uvavanyo lobuchwephesha lobunjineli.

Umbane ngomnye umba. Izikrini ezicacileyo zisebenzisa i-200-600 watts ngemitha yesikwere. Kwi-100 square metres, yi-20-60 kilowatts. Ngaba inkqubo yokuhambisa umbane yanele? Ngaba iintambo zombane ezizinikeleyo ziyafuneka?

Kuthekani ngokuchitha ubushushu? Ii-LED zivelisa ubushushu, kwaye iindonga zekhethini zeglasi aziphefumli. Isithuba phakathi kwesikrini kunye neglasi siba shushu kakhulu, ngakumbi kumazantsi{1}}ejongene neefacade ehlotyeni. Ngaphandle kokujongana nokutshatyalaliswa kobushushu, ixesha lokuphila kwesikrini lihlupheka kakhulu.

Ulungelelwaniso lokwakha nalo luyingxaki. Kwizakhiwo ezitsha, izikrini ezicacileyo kufuneka zilungelelaniswe kunye noyilo lwamakhethini kwangaphambili. Kwiiprojekthi zokuhlaziya, umsebenzi wangaphandle we-facade unokufuna imvume. Izakhiwo zorhwebo nazo kufuneka ziqwalasele indlela ulwakhiwo oluyichaphazela ngayo imisebenzi yoshishino.

Oku kuyinyani "ukwenza ngokwezifiso"{0}akuko ukwenza isikrini, kodwa ukwenza isisombululo esipheleleyo. Abavelisi okanye abahlanganisi abakuthathela ingqalelo konke oku ngabo abanakho ukunikezela ngesakhono sokwenyani. Abo bathetha kuphela ngezikrini ngaphandle kokuxoxa ngofakelo balindele ukuhlawulisa ngaphezulu kamva okanye baceba ukunyamalala emva kokuziswa.

Umgca ongezantsi

Igama elithi "customization" lenza izikrini ze-LED ezicacileyo zibonakale zinamandla onke. Kodwa eneneni, le yimveliso yamashishini evuthiweyo enemida ecacileyo yobugcisa kunye nemigaqo yezoqoqosho.

Yintoni abanokuyenza abavelisi kukunceda ukufumana ulungelelwaniso oluchanekileyo ngaphakathi kwesakhelo sobugcisa esisekiweyo. Into abangenakuyenza abavelisi kukuchasa imithetho yefiziksi.

Kunokuba ubuze "ingaba inokwenziwa ngokwezifiso," buza "yintoni efunekayo ngokwenene?" Bonisa umgama wokubukela, ukuqaqamba kwendawo, iimeko zofakelo, kunye nemida yohlahlo lwabiwo-mali. Nje ukuba le miqobo ichazwe, isisombululo esona silungileyo siyavela ngokwendalo. Okunye kukufumana umenzi othembekileyo oza kuwenza.
