Ethintwa yi-Covid-19,Abakhiqizi besikrini esobalabanaka kakhulu ocwaningweni nasekuthuthukisweni, ehlukanisa amazinga esikrini, umhlangano kanye nemiphumela yokukhiqiza. Impi yentengo engabonakali yenza kube nzima ukuthi abakhiqizi bomhlangano basinde, futhi abakhiqizi abanamandla bayakwazi ukugxila ekuthuthukiseni imikhiqizo yokushintshashintsha kwentengo ebonakalayo emakethe yokushintshashintsha kwentengo yokushintshana kwamanani entengo,, ngaleyo ndlela kuphume.
Ngokwanda kwesidingo semakethe, ubuchwepheshe besikrini esibonakalayo kanye nemikhiqizo yenzelwe ngokuqhubekayo, futhi nobuchwepheshe obusebenzayo buvele, buveze futhi okuhlangenwe nakho okuhle. Ngokwehliswa okuqhubekayo kwePixel Pitch kanye nokwenza ngcono ukuvumela nokuqina, izikrini ezisobala ze-LED zithathe kancane kancane emakethe ngezimpawu ezinesifundo esiphakeme kanye nezinto ezibonakalayo, futhi zithola isikhundla esibalulekile emkhakheni wezindonga zeglasi.
Ngokuvuthwa kokusobala kwe-LED, izikrini zefilimu ze-LED, izikrini zengilazi, kanye nezikrini zefilimu ze-Crystal ziye zaba yimisebenzi emele izikhala, futhi izikrini ezisobala ezicashile ziye zaba yindlela entsha. Ukuthuthukiswa kanye nokusetshenziswa kwale mikhiqizo yesikrini ebonakalayo ecashile kubonile ukuthuthuka okusheshayo kwezikrini ezisobala.
Ngenxa yokugcwala kancane kancane kwemakethe yesikrini esijwayelekile yokubonisa isikrini kanye nemikhawulo yokusetshenziswa kwayo emikhakheni enjengezindonga ze-Glass Curtain. Ukwenza ngcono lesi simo, izikrini ezisobala zaholwa zizelwe futhi zihlakulele ngokushesha kusukela ngo-2017, ziya ngokuya zithandwa yimakethe. Ngasikhathi sinye, ekuhlelweni kwamadolobha nasekwakheni, izakhiwo zobunjiniyela ze-Glass Window zithandwa kakhulu, eziholele ekuqubukeni kwezikrini ezisobala zangaphakathi. Ukuhlola izakhiwo zobunjiniyela ze-Glass ngemfashini, ukwehluka kombala, kwangemuva, kanye nomqondo wezobuchwepheshe, kunikeza abantu inkulumo eyingqayizivele. Izikrini ezisobala ze-LED ziyaqhubeka nokuqhuma, ngamakhono amakhulu emakethe. Ngokusho kokubikezela, inani lokukhipha lemakethe le-LED Transrefent Screens lizoba cishe amabhiliyoni ayi-10 billion ngo-2025.
Eminyakeni yamuva nje, kwaqhamuka umqondo wokuthi "izitolo ezintsha", futhi izikrini ezisobala zibe neqhaza elibalulekile endiwene yezentengiselwano yokuthengisa, umhlobiso wangaphakathi, ama-facades, kanye nezinye izinkambu, okwenza izinguquko ezinkulu ekuthengisweni okusha. Ukwehluka kanye nomuzwa wobuchwepheshe kwakha isipiliyoni esingcono sokuthenga ngenkathi ungayekethisi ukwakheka kwamafasitela okubukisa kanye nama-storefronts. Imikhiqizo eminingi yemfashini, izimoto, ubucwebe kanye neminye imikhiqizo ephezulu kakhulu nayo ikhetha ukusebenzisa izikrini ezisobala ze-LED ukukhulisa isitayela somkhiqizo. Lapho udlala okuqukethwe kokuphromotha, izizinda ezisobala azikwazi ukukhulisa kuphela umqondo wezobuchwepheshe. Ukuvela kokuthengiswa okusha kuzoshayela ngokungenakuphikwa kwezentengiso zemakethe yokubonisa yezentengiso futhi wakhe isidingo esithile sezikrini ezibonakalayo ezisobala.
Ngenxa yohlobo olusobala lwezikrini ze-LED, ukucaca kwazo kuthinteka ngokungafanele. Ungakuthola kanjani ukucaca okuphezulu ngaphandle kokuthinta obala kuyinselelo yezobuchwepheshe okudingeka inqotshwe.
1. Ukusingatha kanjani i-grayscale okubangelwa ukunciphisa ukugqama kwezikrini ezisobala ze-LED?
Lapho usebenzisa isikrini esikhishwe esibonakalayo njengesikrini sokubonisa esiholwa ngaphakathi, ukugqama kudinga ukwehliswa, uma kungenjalo, amehlo abantu ngeke akwazi ukubheka isikhathi eside. Kodwa-ke, njengoba ukugqama kuncipha, isithombe sizoba nokulahleka okukhulu kwe-grayscale. Njengoba ukugqama kuyancipha, ukulahleka kwe-greyscale kuba nzima ngokwengeziwe. Siyazi ukuthi ukukhuphuka okuphezulu kwe-greyscale, okucasulayo imibala ekhonjiswe esikrinini esibonakalayo, futhi kubuthaka ngokwengeziwe futhi kugcwele isithombe.
Isixazululo sokwehlisa ukugqama kwezikrini ezisobala ze-LED ngaphandle kokuthinta i-grayscale: Ukukhanya komzimba wesikrini kulungele ukugqama kwemvelo futhi kungalungiswa ngokuzenzakalelayo. Gwema umthelela wezindawo ezigqamile ngokweqile noma ezimnyama ukuqinisekisa ikhwalithi yesithombe esejwayelekile. Ngasikhathi sinye, izikrini eziphakeme ze-grayscale ziyasetshenziswa, futhi izinga lamanje le-grayscale lingafinyelela i-16bit.
2. Xazulula umonakalo odalwe yi-LED Transparent Screen ukuthuthukisa ukucaciselwa
Lapho kukhanya ukucaca kwesikrini esibonakalayo esibonakalayo kanye nokucebisa imininingwane yesithombe, ubuhlalu obuholwa kakhulu ngaphakathi kwemodyuli eyodwa buzokwanda futhi basatshalaliswa kakhulu. I-General Light for Izinga lokulimala kwezibani zesikrini esiholwayo ukulilawula kungakapheli 3/10000, kepha ngemodeli encane ye-LED esobala, izinga lokulimala kwezibani ezi-3/900 alikwazi ukufeza izidingo zokusetshenziswa kwansuku zonke. Isibonelo, imodeli ye-P3 eholwa yi-PROD esobala inezindawo ezingaphezu kuka-110000 ubuhlalu ngemitha yesikwele ngasinye. Ukuthatha indawo yesikrini emamitha-skwele amamitha amane, inani lamalambu alonakalisiwe lizoba ngo-11 * 3 * 4 = 132, elizoletha okuhlangenwe nakho okubucayi kokuboniswa kwesikrini okujwayelekile.
Ukulimala kwesibani kuvame ngenxa ye-welding evulekile yobuhlalu besibani. Ngakolunye uhlangothi, kungenxa yenqubo yokukhiqiza engeyinhle yomkhiqizi wesikrini esobala we-LED, futhi futhi ngenxa yezinkinga zokuhlola ezisezingeni. Vele, inkinga yobuhlalu besibani ayinakukhishwa. Ngakho-ke kuyadingeka ukulandela inqubo yokuhlola esezingeni elifanele ukulawula ikhwalithi yezinto zokusetshenziswa ngenkathi kuqapha inqubo yokukhiqiza endaweni. Ngaphambi kokusuka efektri, kuyadingeka ukwenza isivivinyo samahora angama-72 ukuxazulula noma yimuphi umonakalo kumalambu futhi uqinisekise ukuthi yimikhiqizo efanelekile ngaphambi kokuthumela.
3. Ukuchaza okujwayelekile noma ukwenza ngokwezifiso?
Inkinga enkulu ene-LED esobala izikrini okwamanje ukwenza ngokwezifiso. Kunemikhiqizo eminingi eyenziwe ngezifiso emakethe, futhi umjikelezo wokukhiqiza wemikhiqizo eyenziwe ngezifiso yisikhathi eside, kufaka phakathi inqubo ye-R & D. Azisheshe njengamanje njengemikhiqizo evuthiwe futhi kunzima ukukhiqiza ngamanani amakhulu. Ngaphezu kwalokho, njengoba kwaziwa kahle, ubuhlalu be-LED obuholwa abaseceleni obusetshenziselwa ukuboniswa okusobala okuholwa yimakethe akuyona yonke indawo, ngokuqina okumpofu nokuqina, okuholela ekukhiqizweni okuphezulu, okuholela ekuthengisweni ngemuva kokuthengisa.
Kunesinye futhi isizathu esibalulekile njengamanje esivimbela ukuthuthukiswa kwezikrini ezisobala ze-LED - izindleko zokugcina eziphezulu. Cishe yonke imikhiqizo yesikrini esobala ye-LED isetshenziselwa amaphrojekthi wobunjiniyela abakhulu, futhi ubunzima bokulungisa bubonakala. Ngakho-ke, ukukhiqizwa okujwayelekile kanye nokwakhiwa kwezinsizakalo ze-LED Transparents kufakwe ku-ajenda futhi kusetshenziswe amafektri athile amakhulu. Esikhathini esizayo, imikhiqizo esezingeni eliphakeme esobala ingafaka amasayithi wesicelo esingakhethekile.
4. Ukuqapha kokukhetha ukugqama kwesikrini esibonakalayo se-LED
Emkhakheni wokulondolozwa kwamandla nokuvikelwa kwemvelo, abakhiqizi besikrini abahola phambili bathuthukise kakhulu ukusetshenziswa kwamandla kwesikrini. Ngokusebenzisa ama-chip akhipha ama-chips anokusebenza okukhanyayo okukhanyayo futhi aqinisekise ukuthi akukho amakhona okusika noma ukushintshwa kwamandla okushintsha okusebenzayo, ukusebenza kahle kokuguqulwa kwamandla kuthuthukiswe kakhulu. Baphinde bamukele ukudicilela phansi kwephaneli okuklanywe kahle ukwehlisa ukusetshenziswa kwamandla kwabalandeli, kwaklanywa ngokusobala uhlelo lokujikeleza okuphelele, futhi kuncishiswe ukusetshenziswa kwamandla kwezindawo zangaphakathi ngokusho kwezinguquko endaweni engcono.
Izinto ze-luminescent ezisetshenziswe kwizikrini ezisobala ze-LED zinomphumela wokulondolozwa kwamandla nokusetshenziswa okuphansi. Kodwa-ke, ngokubheka ukusetshenziswa kwazo kwizimo ezinezindawo ezinkulu zokubonisa, uma kusetshenziselwa isikhathi eside, ukusetshenziswa kwamandla okuphelele kusazoba phezulu, futhi izikweletu zikagesi ezithwelwe abakhangisi nazo zizokhombisa ukwanda kwejometri. Ngakho-ke, ukuthi ungakufinyelela kanjani ukongiwa kwamandla kuyinkinga ukuthi bonke abakhiqizi besikrini abahola phambili badinga ukucubungula.
