Ethintwa yi-Covid-19,I-LED abakhiqizi besikrini esibonakalayobanake kakhulu ucwaningo nentuthuko, behlukanisa amazinga esikrini abonisa ngale, ukuhlanganisa, kanye nemiphumela yokukhiqiza umkhiqizo. Impi yentengo engabonakali yenza kube nzima kubakhiqizi bomhlangano ukuthi baphile, futhi abakhiqizi abanamandla bayakwazi ukugxila ekuthuthukiseni imikhiqizo emisha yesikrini esisobala se-LED emakethe yokuguquguquka kwentengo nokungafani, ngaleyo ndlela bavelele.
Ngokukhula kwesidingo semakethe, ubuchwepheshe besikrini esikhanyelayo se-LED kanye nemikhiqizo kuthuthukiswa ngokuqhubekayo, futhi ngisho nobuchwepheshe bokusebenzisana sebuvele, okuqhubeka nokuletha okuhlangenwe nakho okuhle. Ngokuncishiswa okuqhubekayo kokuphakama kwephikseli kanye nokuthuthukiswa kokungena nokuzinza, izikrini ze-LED ezibonisa izinto kancane kancane ziye zangena emakethe ngezici zokucaca okuphezulu nokucaca, futhi zithatha isikhundla esibalulekile emkhakheni wezindonga zamakhethini engilazi.
Ngokuvuthwa kokukhanyela kwe-LED, izikrini zefilimu ze-LED, izikrini zengilazi, nezikrini zefilimu eyikristalu seziphenduke imisebenzi emele evelele, futhi izikrini ezibonisa ukukhanya ezinezikhala ezincane seziphenduke indlela entsha. Ukuthuthukiswa nokusetshenziswa kwale mikhiqizo yesikrini esikhanyelayo ehlukaniswe izingxenye ibone ukuthuthuka okusheshayo kwezikrini ezibonisa ngale.
Ngenxa yokugcwala kancane kancane kwemakethe yesikrini esibonisiwe se-LED evamile kanye nemikhawulo yokusetshenziswa kwayo ezinkambeni ezifana nezindonga zamakhethini engilazi. Ukwenza ngcono lesi simo, izikrini ze-LED ezibonisa ngale ziye zazalwa futhi zikhula ngokushesha kusukela ngo-2017, ziya ngokuya zithola umusa wemakethe. Ngesikhathi esifanayo, ekuhleleni nasekwakhiweni kwamadolobha, izakhiwo zobunjiniyela befasitela lezingilazi zithandwa kakhulu, okuye kwaholela ekuveleni kwezikrini zangaphakathi ze-LED ezibonakalayo. Ukunikeza izakhiwo zobunjiniyela bezingilazi ngemfashini, ukuhlukahluka kombala, isimanjemanje, nomuzwa wobuchwepheshe, kunikeza abantu isisho esiyingqayizivele. Izikrini ze-LED ezibonisa ngale ziyaqhubeka nokuqhuma, ezinamandla amakhulu emakethe. Ngokwezibikezelo, inani eliphuma emakethe lezikrini ezibonisa ngale ze-LED lizoba cishe ama-yuan ayizigidi eziyizinkulungwane eziyi-10 ngo-2025.
Eminyakeni yamuva nje, umqondo "wokuthengisa okusha" uvele, futhi izikrini ezibonakalayo ze-LED ziye zadlala indima ebalulekile ekuboniseni amafasitela okuthengisa, ukuhlobisa kwangaphakathi, ama-facade wokwakha, nezinye izinkambu, okuletha izinguquko ezinkulu ekuthengiseni okusha. Umehluko nomuzwa wobuchwepheshe kudala umuzwa ongcono wokuthenga kuyilapho kungafaki engcupheni idizayini yamawindi ombukiso nangaphambili kwesitolo. Imikhiqizo eminingi yemfashini, izimoto, ubucwebe neminye imikhiqizo esezingeni eliphezulu ikhetha ukusebenzisa izikrini ezibonisa ngale ze-LED ukuthuthukisa isitayela somkhiqizo. Uma udlala okuqukethwe kokuphromotha, ingemuva elisobala alikwazi nje ukukhulisa umqondo wobuchwepheshe. Ukuvela kokuthengisa okusha kuzoshayela nakanjani ukuthuthukiswa kwemakethe yokubonisa ezohwebo futhi kudale isidingo esithile sezikrini ze-LED ezibonisa ngale.
Ngenxa yemvelo esobala yezikrini ze-LED, ukucaca kwazo kuthinteka nakanjani. Indlela yokuthola ukucaca okuphezulu ngaphandle kokuthikameza ukubonakala kuyinselele yobuchwepheshe okudingeka inqotshwe.
1. Indlela yokusingatha i-grayscale ebangelwa ukunciphisa ukukhanya kwezikrini ezibonakalayo ze-LED?
Uma usebenzisa isikrini se-LED esibonisa ngale njengesikrini se-LED sasendlini, ukukhanya kudinga ukuncishiswa, ngaphandle kwalokho, amehlo abantu ngeke akwazi ukubekezelela ukubuka isikhathi eside. Nokho, njengoba ukukhanya kuncipha, isithombe sizoba nokulahlekelwa okukhulu kwe-grayscale. Njengoba ukukhanya kuncipha, ukulahleka kwe-grayscale kuba nzima kakhulu. Siyazi ukuthi ukuphakama kweleveli ye-grayscale, imibala ekhonjiswa esikrinini esikhanyela ngokucebile, kanye nesithombe esithambile nesigcwele.
Isixazululo sokunciphisa ukukhanya kwezikrini ze-LED ezibonisa ngale ngaphandle kokuthikameza okumpunga: Ukukhanya komzimba wesikrini kulungele ukukhanya kwemvelo futhi kungalungiswa ngokuzenzakalelayo. Gwema umthelela wezindawo ezikhanya ngokwedlulele noma ezimnyama ukuze uqinisekise ikhwalithi yesithombe evamile. Ngesikhathi esifanayo, kusetshenziswa izikrini ezimpunga eziphakeme, futhi izinga lamanje le-grayscale lingafinyelela ku-16bit.
2. Xazulula umonakalo odalwe isikrini esisobala se-LED ukuze uthuthukise ukucaca
Uma kuphakeme ukucaca kwesikrini se-LED esibonisa ngale kanye nemininingwane yesithombe inothile, buyanda ubuhlalu be-LED ngaphakathi kwemojuli eyodwa futhi busakazeke kakhulu. Izinga elijwayelekile lezinga lokulimala kwezibani zesikrini sokubonisa i-LED wukulawula ngaphakathi kuka-3/10000, kodwa kumamodeli amancane wezikrini ezibonisa ngale ze-LED, izinga lokulimala kwezibani ezingu-3/10000 alikwazi ukuhlangabezana nezidingo zokusetshenziswa kwansuku zonke. Isibonelo, imodeli ye-P3 yesikrini esibonisa ngale LED inobuhlalu bokukhanya obungaphezu kuka-110000 ngemitha yesikwele ngayinye. Uma kubhekwa indawo yesikrini engamamitha-skwele angu-4, inani lezibani ezilimele lizoba ngu-11 * 3 * 4=132, okuzoletha okuhlangenwe nakho kokubuka okungenabungane kusibonisi sesikrini esivamile.
Ukulimala kwesibani ngokuvamile kubangelwa ukushisela okuxekethile kobuhlalu besibani. Ngakolunye uhlangothi, kungenxa yenqubo embi yokukhiqiza yomkhiqizi wesikrini esibonakalayo se-LED, nangenxa yezinkinga zokuhlolwa kwekhwalithi. Yiqiniso, inkinga yobuhlalu besibani ayikwazi ukuchithwa. Ngakho-ke kuyadingeka ukulandela inqubo yokuhlola ikhwalithi ehlelekile ukuze ulawule ikhwalithi yezinto ezingavuthiwe ngenkathi uqapha inqubo yokukhiqiza ekhona. Ngaphambi kokushiya imboni, kuyadingeka ukwenza ukuhlolwa kwamahora angu-72 ukuze kuxazululwe noma yikuphi ukulimala kwezibani nokuqinisekisa ukuthi ziyimikhiqizo efanelekayo ngaphambi kokuthunyelwa.
3. Ukumisa noma ukwenza ngokwezifiso?
Inkinga enkulu ngezikrini ezibonisa ngale ze-LED okwamanje ukwenza ngokwezifiso. Kunemikhiqizo eminingi eyenziwe ngokwezifiso emakethe, futhi umjikelezo wokukhiqiza wemikhiqizo eyenziwe ngezifiso mude uma kuqhathaniswa, okuhlanganisa nenqubo ye-R&D. Ayisheshi njengemikhiqizo evuthiwe njengamanje futhi kunzima ukuyikhiqiza ngobuningi. Ngaphezu kwalokho, njengoba kwaziwa kahle, ubuhlalu be-LED obuseceleni obusetshenziselwa ukubonisa okusobala kwe-LED emakethe abuyona indawo yonke, nokungaguquguquki okubi nokuzinza, okuholela ezindlekweni zokukhiqiza eziphezulu, isivuno esiphansi, kanye nensizakalo enzima yokuthengisa ngemva kokuthengisa.
Kunesinye isizathu esibalulekile esivimbela okwamanje ukuthuthukiswa kwezikrini ezibonisa izinto ze-LED - izindleko eziphezulu zokunakekela. Cishe yonke imikhiqizo yesikrini ebonisa ngale ye-LED isetshenziselwa amaphrojekthi amakhulu wobunjiniyela, futhi ubunzima bokulungisa buyabonakala. Ngakho-ke, ukukhiqizwa okujwayelekile kanye nokwakhiwa kwesevisi yezikrini ezibonisa ngale ze-LED kufakwe ku-ajenda futhi kwaqaliswa ezinye izimboni ezinkulu. Ngokuzayo, imikhiqizo yesikrini ebonisa ngale esezingeni eliphezulu ingase ingene kumasayithi ohlelo lokusebenza angakhethekile.
4. Izinyathelo zokuphepha zokukhetha ukukhanya kwesikrini se-LED esibonisa ngale
Emkhakheni wokongiwa kwamandla nokuvikelwa kwemvelo, abakhiqizi besikrini esibonisa ngale ye-LED bathuthukise kakhulu ukusetshenziswa kwamandla kwesikrini. Ngokusebenzisa ama-chips akhiphayo e-LED anokukhanya okuphezulu okuphezulu nokusebenza kahle kanye nokuqinisekisa ukuthi awekho amakhona okusika noma ukunikezwa kwamandla okushintshwa okuphumelelayo, ukusebenza kahle kokuguqulwa kwamandla kuye kwathuthukiswa kakhulu. Baphinde bamukele ukuchithwa kokushisa kwephaneli okuklanywe kahle ukuze kuncishiswe ukusetshenziswa kwamandla abalandeli, baklame ngokwesayensi uhlelo lomjikelezo jikelele, futhi banciphisa ukusetshenziswa kwamandla kwamasekhethi angaphakathi ngokuvumelana nezinguquko endaweni yangaphandle, Ukukhanya kungalungiswa ngokuzenzakalelayo ukuze kuzuzwe ukonga okungcono kwamandla.
Izinto ze-luminescent ezisetshenziswa ezikrinini ezisobala ze-LED zinomthelela wokonga amandla nokusetshenziswa okuphansi. Kodwa-ke, uma kucatshangelwa isicelo sabo ezigcawini ezinezindawo ezinkulu zokubonisa, uma zisetshenziswe isikhathi eside, ukusetshenziswa kwamandla jikelele kusazoba phezulu, futhi izikweletu zikagesi ezithwalwa abakhangisi zizobonisa ukwanda kwejometri. Ngakho-ke, indlela yokufeza ukongiwa kwamandla kuyinkinga okufanele bonke abakhiqizi besikrini esibonakalayo se-LED bacabangele.
