Emkhakheni wokuboniswa, uma sishoIzibonisi ze-LED, sikholelwa ukuthi wonke umuntu angafaka kuhlu izinzuzo zakhe eziningi, njengokuthi "okukhulu" kanye "nokugqama", amaphikseli aphezulu, akukho ukuhlanganisa, kanye ne-gamut yombala obanzi.Futhi izikrini zokubonisa ze-LED ziphinde zaqhudelana kakhulu ne-LCD, i-projection, nezinye izinkambu kunkundla yokubonisa ngenxa yalezi zinzuzo.Amagama anjengokuthi "isikrini esikhulu" kanye "nesikrini esikhulu" agcwele ukutuswa kwezikrini ezibonisa i-LED.Ngaphandle kokungabaza, inzuzo enkulu yezikrini zokubonisa ze-LED ukuthi "zinkulu futhi azinamthungo".Ukuncintisana phakathi kwezikrini zokubonisa ze-LCD nezikrini zokubonisa ze-LED kusashube kodwa kuzinzile, kodwa ngokuthuthuka kobuchwepheshe, izikrini zokubonisa ze-LED ziya ngokuya zikhula ezimeni zezicelo ze-pitch terminal futhi zibamba ezinye zemakethe yesikrini se-LCD.Ukungena endaweni yokubonisa ezohwebo kusuka emakethe yezinhlelo zokusebenza ezichwepheshile, ububanzi bohlelo lokusebenza lwezibonisi ze-LED bukhula njalo, futhi indlela yakho yokuthuthuka kungathiwa isuka "enkulu" iye "encane".
Ngaphambi kokuthuthuka nokuvuthwa kobuchwepheshe bokubonisa i-LED, ubuchwepheshe bokubonisa isikrini esikhulu emakethe kwakuyi-DLP kanye ne-LCD ehlanganisa izikrini ezinkulu.Izikrini zakuqala ezinkulu kakhulu zazakhiwe ngokuyinhloko izibonisi eziningi ze-DLP ezinemiphetho emincane yonqenqema.Ngokuvela kwezibonisi ze-LCD ezinezinzuzo zamanani, isabelo semakethe se-LCD esihlanganisa izikrini ezinkulu sakhula kancane kancane.Ukuphindwaphindwa kwemikhiqizo yokubonisa i-LCD yokuhlanganisa kubonakala ikakhulukazi ezinkomba zobuchwepheshe ezimbili, eyodwa iyathunga, kanti enye iwukukhanya.Ngenxa yezici zokubonisa zezibonisi ze-LCD, akunakwenzeka ukuthola izinga eliphezulu lokukhanya, futhi isidingo sezimo zohlelo lokusebenza lokubonisa ngaphandle nangaphandle siyavela kancane kancane.Isidingo samaphaneli wokubonisa ukukhanya okuphezulu avela kubakhiqizi bemishini yonke sikhula ngokushesha, futhi okwamanje, iningi lezicaciso zokukhanya kunzima ukuhlangabezana nesidingo semakethe.Ngalesi sikhathi, izinzuzo zemikhiqizo yesikrini sokubonisa i-LED ziyagqanyiswa.Izikrini zokubonisa ze-LED azikwazi nje ukwakha isistimu yesibonisi yendawo enkulu ngaphandle kwemithungo enqenqemeni, kodwa futhi zifaneleka kakhulu ezindaweni ezinkulu nezivulekile nokubukwa kude ngenxa yesimiso sokukhishwa okuqondile nezici zomumo eziguquguqukayo zemikhiqizo yesikrini sokubonisa i-LED.
Uma sibheka emuva emlandweni wokuthuthukiswa kwezikrini ezinkulu, kuyacaca ukuthi esikhathini esidlule, imakethe yokuhlanganisa isikrini esikhulu empeleni yayisezingeni eliphansi.Ithuthukise kuphela futhi yaguqula izibonisi ze-LCD zedeskithophu yendabuko futhi yazisebenzisa emakethe yokuhlanganisa.Inezihibe eziningi, njengokuxazulula okunganele, ubunzima ekuhlangabezaneni nezinga elidingekayo, futhi esikhathini samanje esinencazelo ephezulu, ayikwazi ukuhlangabezana nezidingo zemakethe.Izibonisi ze-LED zinezinzuzo eziphelele ezinhlelweni zangaphandle, kodwa ngesikhathi esifanayo, ubuchwepheshe bokubonisa obufana ne-LCD kanye nokuqagela nakho kuthuthuke ngokushesha.Uma izibonisi ze-LED zishiya izinhlelo zokusebenza zangaphandle "ezinkulu", hlobo luni lwentuthuko ezingaba nazo ezinhlelweni "ezincane"?
Impi Yesikrini Esikhulu phakathi kwe-LED ne-LCD
Esikhathini sokuqhuma kolwazi, kunezinhlelo zokusebenza eziningi zokuhlanganisa isikrini esikhulu, futhi izimboni zohlelo lokusebenza nazo ziyanda.Kusukela ezimbonini ezivamile zokuphepha zomphakathi, ezokusakaza, nezokuthutha kuye kwezisafufusa zezokuthengisa, ezamabhizinisi, nezinye izimboni, ukuhlanganisa kungabonakala yonke indawo.Ngenxa yobuningi bemakethe nokuncintisana okuqinile, okuvamile kakhulu ukuncintisana phakathi kwe-LED ne-LCD.Eminyakeni yamuva, i-LCD splicing ibonisa imikhiqizo kanyeIzibonisi ze-LEDasetshenziswe kabanzi ekugadweni kwevidiyo, emyalweni nasekuthumeleni, kuncike esidingweni esikhulu semakethe yemboni yezokuphepha emhlabeni wonke.Imikhiqizo yokuhlanganisa ye-LCD inamandla okukhula azinzile.Uma kuqhathaniswa ne-LCD, izibonisi ze-LED zisebenza kakhulu.Ngokuhlomula ngezinqubomgomo nemakethe, izibonisi ze-LED zihamba kancane kancane zisuka ezinkundleni zokubonisa ezingochwepheshe ezifana nokuphepha, ezokuthutha, namandla ziye ezinkundleni zokubonisa ezentengiso ezifana namasinema namagumbi enkomfa.Ngokusho kwedatha, imakethe yesicelo yangaphandle yezikrini zokubonisa ze-LED e-China njengamanje yenza ama-59%.Namuhla, ukusetshenziswa kwezikrini zokubonisa i-LED kuya ngokuya kusakazeka, futhi imvamisa yazo yokubhekana ne-LCD nayo iyanda.Ngakho-ke, yiziphi izinzuzo zezikrini zokubonisa ze-LED uma ziqhathaniswa nemikhiqizo yokubonisa i-LCD yokuhlanganisa?
Isikhala esincane "sokufudumala kwamanje" sikhuphuka
Ngokuthuthukiswa kwesikhala esincane, izikrini zokubonisa ze-LED aziqhakazi ngaphandle kuphela, kodwa futhi zisebenzisa isabelo esithile semakethe emkhakheni wemibukiso yezentengiso yasendlini ngenxa yezinzuzo zazo.Ngokusho kwedatha evela ku-China Academy of Commerce and Industry, imali yokuthengisa ye-pitch pitch LED displays e-China ifinyelele ku-16.5 billion yuan ngo-2022, futhi kulindeleke ukuthi inyuke ibe ngama-yuan ayizigidi eziyizinkulungwane ezingu-18 ngo-2023. Ngokusho kwedatha evela ku-Luotu Technology, ngekota yokuqala ka-2023, ukusetshenziswa kwezibonisi ze-LED ze-pitch encane ezigcawini zengqungquthela cishe kwakuyingxenye, okuhlanganisa ama-46%.Ukugcwaliswa kwezicelo zemiyalo yendabuko/ukuqapha bekuphezulu uma kuqhathaniswa, futhi isabelo semakethe sendawo yokuthunyelwa kwemikhumbi sasingaphansi kwama-20%.Eqinisweni, okwamanje, imibukiso eqondile ye-LED encane izuze ukukhiqizwa kwemikhiqizo emikhulu ye-P0.4 nangaphezulu, futhi isivele idlule imibukiso ye-LCD ezinkomba zephikseli.Ngokuphathelene nokuhlinzekwa kokulungiswa kwezibonisi ezinosayizi omkhulu, zingacishe zihlangabezane nezidingo zanoma isiphi isibonisi.
Emkhakheni wokuboniswa kwesikrini esikhulu, imikhiqizo emincane yokuhlukanisa izikhala inezinzuzo ezisobala, futhi isabelo semakethe kulindeleke ukuthi siqhubeke sikhula.Iisikrini esincane se-LED sokubonisaisebenzisa ubuchwepheshe bokulawula iphuzu le-pixel ukuze kuzuzwe ukulawula isimo sokukhanya, ukubuyiselwa kombala, nokufana kweyunithi yesibonisi.Uma kuqhathaniswa nemithombo ye-backlight evamile, imithombo emincane yokukhanya kwe-LED ye-pitch inohlu olugxilisiwe lwamaza okukhishwa kwamaza, isivinini sokuphendula esisheshayo, kanye nezinzuzo eziningi uma kuqhathaniswa namadivayisi wokubonisa we-LED ovamile.Ngaso leso sikhathi, indawo enkulu yokubonisa ezentengiselwano kanye nezinkambu zokusetshenziswa kwekhaya nazo ziyisiqondiso sokungena ebangeni elincane esikhathini esizayo, futhi abakhiqizi abakhulu balungiselela ngenkuthalo imakethe yokubonisa ezohwebo.Ngaphezu kwalokho, ukuthuthuka okusheshayo kwemakethe yezamasiko nezokuvakasha kulethe namathuba amaningi okufaka izicelo zokuboniswa kwe-LED emkhakheni wemibukiso yezentengiso.Ukubuyekezwa kwamamodeli okusebenza emikhakheni eminingi, okuhlanganisa amamuvi, ukukhangisa, ezemidlalo, nokuzijabulisa, kuyaqhubeka nokuqhuba ukuchuma kwezibukiso zezentengiso.Kuzinhlelo zokuqagela, ukuqagela okujwayelekile kuhlala kubhekene "ne-brightness bottleneck" kanye "ne-resolution bottleneck" ezikrinini ezinkulu.Lezi zingqinamba ezimbili zobuchwepheshe ziyizinzuzo ezinkulu zama-LED amancane.Ngaphezu kwalokho, ngokuthandwa okwandayo kwe-HDR namuhla, amasistimu wokuqagela weprojektha nawo awakwazi ukufeza ikhono lokulawula ukunemba kwesikrini se-LED ukuze afinyelele ukulungiswa kokukhanya "kwe-pixel encane nge-pixel".Isikrini esincane se-LED se-pitch display singafinyelela isibonisi esingu-8K, okusenza sibe namandla nakakhulu.
Kafushane, ukuthuthukiswa kwezibonisi ze-LED kuyinqubo yokugxila ekubonisweni okukhethekile kanye nokuhlola izibonisi zezentengiso.Phakathi naleso sikhathi, ekuthuthukisweni kwezikrini zokubonisa i-LED kusukela "enkulu" kuya "encane" futhi kusukela "kuncane" kuya "kuncane", kuzokwenzekani ngezikrini zokubonisa i-LED lapho "enkulu" ingaseyona inzuzo?
Ukusuka kokuthi "B" kuye ku-"C" kusadinga imizamo ehlanganyelwe kusukela embonini yokubonisa i-LED
Eminyakeni yamuva nje, ngokuncipha kwentengo nezindleko, ukuphumelela kwezindleko zokuboniswa kwe-pitch encane ye-LED kuye kwagqama kakhulu, futhi ukumiselela kwazo i-LCD kuye kwaba namandla.Izibonisi ze-LED ziye zanda kancane kancane kusukela emikhakheni yobungcweti kuya kumkhakha wefilimu nekhaya.Ukuze uqhubekele phambili, isikhala samachashazi sezikrini zokubonisa ze-LED sihlala sincipha, sithuthukela ekuchazeni okuphezulu kanye nencazelo ephezulu kakhulu, silwela ukuncintisana nobunye ubuchwepheshe bokubonisa kanye nokungena ngokuqhubekayo emakethe ekhona yobunye ubuchwepheshe bokuboniswa.Nokho, ngesikhathi esifanayo, impumelelo noma ukwehluleka kobuchwepheshe bokubonisa obufana ne-LED ne-LCD ezinhlelweni ezisebenzayo akunqunywa kuphela izinga lobuchwepheshe nemikhiqizo.Esimeni samanje, izici zobuchwepheshe zezikrini zokubonisa ze-LED zithuthukiswa ngokuqhubekayo futhi imikhiqizo ithuthukiswa njalo.Nokho, ngesikhathi esifanayo, ubuchwepheshe bokuboniswa kwe-LCD buye benza intuthuko ngokushesha, benza inqubekelaphambili ebalulekile ekubonisweni kombala, i-engeli ebonakalayo, isikhathi sokuphendula, nezinye izici.Mayelana nokusebenza, iphinde yahlanganisa ezinye zezinzuzo ze-LED.Kule nqubo yokuncintisana, nakuba intengo yezikrini zokubonisa i-LED ibonise umkhuba ophansi, uma kuqhathaniswa ne-LCD kanye ne-projection, zisesenani eliphezulu lesibhakabhaka.Ezikrinini zokubonisa ze-LED, kusenomgoqo ngaphambi kokusuka kokuthi "B" kuye ku-"C".Ukuze unqamule amaketanga entengo, yonke imboni yokubonisa i-LED idinga ukusebenzisana ukuze ithuthuke.
Ngaphezu kokuphula imingcele yamanani, enye into ebalulekileIsikrini sokubonisa se-LEDimikhiqizo ezosuka ku-B iye ku-C-end yindlela yokubhekana kangcono nesidingo somkhiqizo ochithekile esimweni sokuthuthukiswa kwabathengi.Uma sibheka emuva emlandweni wokuthuthukiswa kwamaphaneli kamabonakude, kusukela kubuchwepheshe be-CRT kuya kubuchwepheshe be-LCD ne-OLED, futhi manje kuya kubuchwepheshe obudumile be-Mini LED kanye ne-Micro LED, sekukonke, ukusungulwa kwemboni yamaphaneli kamabonakude kuhamba kancane, kodwa ukusungulwa ngakunye kwezobuchwepheshe kuletha umthelela ophazamisayo.Uma kuqhathaniswa ne-LCD, i-Micro LED ayikazuzi ukukhiqizwa ngobuningi emkhakheni wephaneli ye-TV ngenxa yezindleko zayo eziphezulu.Njengamanje, indlela yokuthuthukisa ukusebenza nokuncintisana kwezindleko zezikrini zokubonisa ze-LED ezinezinkomba ezikhona zokuhlukanisa izikhala, ukuze kutholwe imakethe enkulu, isiphenduke umsebenzi obalulekile kumabhizinisi embonini.Ukuthuthukiswa kwezinqubo zokukhiqiza ngobuningi, ukuhlolwa kwezakhiwo ezintsha zokupakisha, ukwamukelwa kwama-chip amancane/amancane e-LED, nokwanda kwesikali nobuhlakani bokukhiqiza konke sekuphenduke izinketho.Lesi sakhiwo esincintisanayo sisiza kakhulu ekwandeni kwemakethe yabathengi embonini, ngobuchwepheshe obuningi futhi kugxilwe ekwehliseni izindleko, okungase futhi kukhuthaze ukukhula okuqhubekayo kosayizi wemakethe yokubonisa i-LED.
Izinguquko zesikhathi esizayo zokuma komhlaba azikaziwa, kodwa esikhathini samanje semikhiqizo ehlukahlukene yokubonisa futhi eqhudelana ngombono wabathengi, imboni yokubonisa ye-LED iyonke kusadingeka ukuthi ihlolwe kabanzi: yiziphi ezinye izici okufanele i-LED ibonise imikhiqizo engavula kangcono imakethe yasekhaya. unayo?Kufanele sisondele kanjani emakethe yabathengi?Kubakhiqizi besikrini sokubonisa i-LED, ngaphezu kokubamba izinzuzo zabo zobuchwepheshe, bangadinga futhi ukucabangela ukunweba nokunwetshwa ezinkambini eziningi.
