Emkhakheni wokuboniswa, lapho sikhulumaUkuboniswa kwe-LED, Sikholwa ukuthi wonke umuntu angabhala izinzuzo zawo eziningi, njenge "enkulu" futhi "ekhanyayo", i-pixel ephezulu, akukho ukuhlukaniswa kombala obanzi. Futhi izikrini zokubonisa ze-LED ziphinde zancintisana nge-LCD, Projection, kanye nezinye izinkambu enkundleni yokubonisa ngenxa yalezi zinzuzo. Amagama afana ne- "Screen Big" kanye "nesikrini esikhulu" agcwele ukunconywa ngezikrini zokubonisa eziholwa. Ngaphandle kokungabaza, inzuzo enkulu kunazo zonke izikrini zokubonisa eziholwayo ukuthi "zinkulu futhi zingenamthungo". Umncintiswano phakathi kwezikrini zokubonisa ze-LCD kanye nezikrini zokubonisa eziholwayo zisavutha kepha zizinzile, kodwa ngokuziphendukela kwezobuchwepheshe, izikrini zokubonisa ze-LED zikhula kancane kancane kwimakethe yesikrini esisezingeni eliphakeme futhi zithatha i-LCD Display Screen Market. Entering the commercial display field from the professional application market, the application scope of LED displays is constantly expanding, and its development path can be said to be from "large" to "small".
Ngaphambi kokuthuthuka nokuvuthwa kobuchwepheshe bombukiso we-LED, ubuchwepheshe obukhulu bokubonisa isikrini esikhulu emakethe kwakuyi-DLP ne-LCD Splicing Screens ezinkulu ezinkulu. Izikrini ezinkulu zakuqala zakhiwa ngokuningiliziwe ze-Multiple DLP ekhombisa ngemishini emincane emincane. Ngokuvela kokuboniswa kwe-LCD ngezinzuzo zentengo, isabelo semakethe se-LCD Splicing Screens ezinkulu kakhulu sandiswa kancane kancane. I-Iteration yemikhiqizo yokubonisa ye-LCD ye-LCD ibonakala ikakhulukazi kwizinkomba ezimbili zobuchwepheshe, enye iyathungatha, kanti enye ingukukhanya. Ngenxa yezimpawu eziboniswayo ze-LCD Ekhombisa, akunakwenzeka ukufeza izinga eliphakeme lokukhanya, kanye nesidingo sezimo zesicelo se-semi ngaphandle nangaphandle sokubonisa kancane kancane. Isidingo sokukhanya okuphezulu kokuboniswa okuvela kusuka kubakhiqizi bomshini wonke bakhula ngokushesha, futhi njengamanje, iningi lezincazelo zokukhanya okukhanyayo kunzima ukuhlangabezana nesidingo semakethe. Ngalesi sikhathi, izinzuzo zemikhiqizo yesikrini yokubonisa isikrini ziyaqokonyiswa. Izikrini zokubonisa ze-LED azikwazi kuphela ukwakha uhlelo olukhulu lokubonisa indawo ngaphandle kwama-seams anqenqemeni, kepha futhi zilungele izindawo ezinkulu ezinkulu nezivulekile nokubukwa okude ngenxa yokubukwa okuqondile kwemikhiqizo ye-LED Display Screen.
Uma ngibheka emuva emlandweni wokuthuthuka kwezikrini ezinkulu, kuyacaca ukuthi esikhathini esidlule, imakethe yokuhlukaniswa kwesikrini okukhulu empeleni kwakuphansi kakhulu. Kuvuselelwa kuphela futhi kwaguqulwa i-Desktop LCD ye-LCD futhi yazisebenzisa emakethe yokuhlukanisa. Inezingqinamba eziningi, njengokulungiswa okunganele, ubunzima bokuhlangabezana nezinga elidingekayo, nasesikhathini sanamuhla esiphezulu, ngeke ihlangabezane nezidingo zemakethe. Ukuboniswa kwe-LED kunezindlela eziphelele kuzinhlelo zokusebenza zangaphandle, kepha ngasikhathi sinye, ubuchwepheshe bokubonisa njenge-LCD ne-Projection buye bathuthuka ngokushesha. Lapho kuboniswa ama-LED kushiya izinhlelo zokusebenza zangaphandle "ezinkulu", hlobo luni lwentuthuko abangathola khona ku- "amancane"?
Impi yesikrini esikhulu phakathi kwe-LED ne-LCD
Esikhathini sokuqhuma kwemininingwane, kunezicelo eziningi ezengeziwe zokuhlukaniswa kwesikrini okukhulu, futhi izimboni zayo zohlelo lokusebenza ziyanda. Ukusuka ekuvikelekeni komphakathi kwendabuko, ukusakaza, kanye nezimboni zokuhamba ezimbonini ezisafufusa ezitolo, ebhizinisini, nakwezinye izimboni, ukuhlukaniswa kungabonakala yonke indawo. Ngenxa yemakethe enkulu kanye nomncintiswano onolaka, okujwayelekile kakhulu ngumncintiswano phakathi kwe-LED ne-LCD. Eminyakeni yamuva nje, i-LCD splicing imikhiqizo yokubonisa futhiUkuboniswa kwe-LEDIsetshenziswe kabanzi ekubhekeni kwevidiyo, umyalo kanye nokuthumela, ukuthembela ekufuneni okukhulu kwemakethe yezimboni zokuphepha emhlabeni jikelele. Imikhiqizo yokubonisa ye-LCD yokubonisa inekhono lokukhula elizinzile. Uma kuqhathaniswa ne-LCD, ukuboniswa kwe-LED kusebenza kakhulu. Ukuzuza ezinqubomgomo nasemakethe, ukuboniswa kwe-LED kancane kancane kuvela emikhakheni yokubonisa yobungcweti efana nokuphepha, izinto zokuhamba, kanye namandla okuthengisa izinkambu ezifana nama-cinema namakamelo engqungquthela. Ngokusho kwemininingwane, imakethe yohlelo lokusebenza lwangaphandle yezikrini zokubonisa ze-LED eChina njengamanje ama-59%. Kulezi zinsuku, ukusetshenziswa kwezikrini zokubonisa ze-LED ziya ngokuya zisakazeka, futhi imvamisa yazo yokuxabana ne-LCD nayo iyanda. Ngakho-ke, yini izinzuzo zezikrini zokubonisa ze-LED ziqhathaniswa nemikhiqizo yokubonisa ye-LCD?
Ukuhlukaniswa okuncane "okufudumele" ukugcwala "okufudumele
Ngokuthuthukiswa kwezikhala ezincanyana zokuhlukanisa izikhala, izikrini zokubonisa eziholwayo hhayi kuphela eziqhakaza ngaphandle, kodwa futhi zihlale futhi ingxenye ethile yemakethe emkhakheni wokuboniswa kwezentengiselwano ngaphakathi ngenxa yezinzuzo zawo. Ngokwemininingwane evela eChina Academy of Commerce kanye nemboni, imali yokuthengisa ye-Little Pitch Led Ekhombisa eChina yafinyelela ku-2022. Ukugcwaliswa kwezicelo zendabuko / zokuqapha kwaqala ukuphakama, futhi isabelo semakethe sendawo yokuthumela sasingaphansi kwama-20%. Eqinisweni, njengamanje, ukuboniswa okuqondile kwe-pitch encane ye-pitch kufinyelele ukukhiqizwa okukhulu kwemikhiqizo ye-P0.4 nangaphezulu, futhi sekudlule ukuboniswa kwe-LCD ekwedlula zonke izinkomba ze-Pixel Pitch Izinkomba. Ngokuya ngokulungiswa kokuxazululwa kwemibukiso enkulu ebanzi, cishe bahlangabezana nezidingo zanoma yikuphi ukuboniswa.
Emkhakheni wokuboniswa kwesikrini esikhulu, imikhiqizo emincane yokuhlukanisa izikhala inezinzuzo ezisobala, futhi isabelo semakethe kulindeleke ukuthi siqhubeke sanda. Le khasiIsikrini esincane se-Pitch Show ScreenI-Adopts Pixel Level Point Control Technology ukufezekisa ukulawulwa kombuso kokukhanya, ukubuyiselwa kombala, kanye nokufana kweyunithi yokubonisa. Uma kuqhathaniswa nemithombo yendabuko yasemuva, imithombo emincane ye-Pitch Led Backlight inohlu oluhlanganisiwe lwe-Emition Wavelengths, isivinini sokuphendula esisheshayo, nezinzuzo eziningi uma ziqhathaniswa namadivayisi okubonisa wendabuko. Ngasikhathi sinye, izinkambu ezinkulu zezentengiselwano kanye nezinkundla zokusebenzisa ikhaya nazo ziyindlela yokungena ekude ibanga elincane ngokuzayo, futhi abakhiqizi abakhulu balungiselela ngenkuthalo imakethe yokubonisa yezentengiso. Ngaphezu kwalokho, ukuthuthukiswa okusheshayo kwemakethe yamasiko nezokuvakasha kubuye kwaletha amanye amathuba okufaka isicelo sokuboniswa kwe-LED emkhakheni wemibukiso yezentengiso. Ukuvuselelwa kwamamodeli okusebenza emasimini amaningi, kufaka phakathi ama-movie, ukukhangisa, ezemidlalo kanye nokuzijabulisa, kuyaqhubeka ukushayela ukuchuma kwemibukiso yezentengiso. Kuzinhlelo ze-Projection, ukuqagela kwendabuko kuhlale kubhekene "nokukhanya kwebhodlela" kanye "nokuxazulula ibhodlela" kwizikrini ezinkulu. La ma-bottleneck amabili wezobuchwepheshe yizinzuzo ezinkulu ze-LEDs encane ye-LED. Ngaphezu kwalokho, ngokuthandwa okukhulayo kwe-HDR namuhla, ama-projector projection systems akwazi nokufinyelela ikhono lokulawula ukunemba kwesikrini okuholwa ukufezekisa "i-pixel ephansi ngoPixel" ukulungiswa kokukhanya. Isikrini sokubonisa isikrini esincane se-LED singafinyelela isibonisi se-8k, okwenza kube namandla ngokwengeziwe.
Ngamafuphi, ukuthuthukiswa kwemibukiso ye-LED inqubo yokugxila ekubonisweni okukhethekile nasekuhlolweni kokuboniswa kwezentengiso. Okwamanje, kwinqubo yokuthuthukisa izikrini zokubonisa ze-LED zivela ku- "Big" to "zincane" futhi zisuka ku- "micro", kuzokwenzekani ku "micro" akusekho inzuzo?
Ukusuka ku- "B" ku- "C" kusadinga imizamo ehlanganyelwe evela embonini yokubonisa ye-LED
Eminyakeni yamuva, ngokuncipha kwentengo nezindleko, ukusebenza kwezindleko zokuboniswa kwamaphimbo amancane we-LED sekuya ngokuya kuvezwa, futhi ukungasebenzi kwawo kwe-LCD sekuqine. Ukuboniswa kwe-LED kukhule kancane kancane kusuka emasimini ochwepheshe kuya kumasimu wefilimu kanye nekhaya. Ukuze uqhubeke nokuqhubeka, ukuhlukaniswa kwe-dot kwezikrini zokubonisa eziholwayo kuhlale kuncipha, kuthuthukiswa ekuchazeni okuphezulu kanye nencazelo ephezulu ye-Ultra, ukulwela ukuncintisana nobunye ubuchwepheshe bokubonisa futhi ngokuqhubekayo ungene emakethe ekhona yobuchwepheshe obukhona. Kodwa-ke, ngasikhathi sinye, impumelelo noma ukwehluleka kobuchwepheshe bokubonisa njenge-LED ne-LCD ezingcemeni ezingokoqobo akunqunywa kuphela ngekhwalithi yezobuchwepheshe nemikhiqizo. Esimweni samanje, izici zobuchwepheshe zezikrini zokubonisa ze-LED ziyenziwa ngokuqhubekayo futhi imikhiqizo ihlala ithuthukiswa. Kodwa-ke, ngasikhathi sinye, ubuchwepheshe bokubonisa kwe-LCD Projection buthuthukiswa ngokushesha, benza inqubekela phambili enkulu ekubonisweni kombala, i-angle ebonakalayo, isikhathi sokuphendula, nezinye izici. Ngokuya ngokusebenza, sekuphinde kwahlanganisa nezinye izinzuzo ze-LED. Kule nqubo yokuncintisana, yize intengo yezikrini zokubonisa eziholwayo ikhombisile ukuthambekela kwehla, uma iqhathaniswa ne-LCD ne-Projection, ziseyintengo ephakeme yesibhakabhaka. Ngezikrini zokubonisa ze-LED, kusekhona isithiyo ngaphambi kokusuka ku- "B" ku- "C". Ukwephula imijondolo yentengo, yonke imboni yokubonisa ye-LED eholwa idinga ukusebenzisana ukuze ithuthuke.
Ngaphezu kwemingcele yentengo, enye into ebalulekile yeIsikrini sokubonisaImikhiqizo yokusuka ku-B-End to the C-End yindlela yokubhekana kangcono nesidingo somkhiqizo weSpillover esimweni sokuthuthukiswa kwabathengi. Uma ngibheka emuva emlandweni wokuthuthuka kwamaphaneli we-TV, kusuka kubuchwepheshe be-CRT kuya kubuchwepheshe be-LCD no-Oled, futhi manje, ukusungulwa komkhakha we-TV adumile, kepha okusha kwezobuchwepheshe kuletha umthelela ophazamisayo. Uma kuqhathaniswa ne-LCD, i-LED eyi-micro ayikafinyeleli ukukhiqizwa kwabantu abaningi ensimini ye-TV Panel ngenxa yezindleko zayo eziphakeme. Njengamanje, ukuthi ungakuthuthukisa kanjani ukusebenza nokuncintisana kwezindleko zezikrini zokubonisa ze-LED ngezikhombisi ezikhona zesikhala, ukuze zithole imakethe enkulu, sekuyimisebenzi eyisisekelo yamabhizinisi embonini. Ukuthuthuka kwezinqubo zokukhiqiza ngobuningi, ukuhlolwa kwezakhiwo ezintsha zokupakisha, ukwamukelwa kwama-chip ama-mini / ama-micro. Lesi sakhiwo sokuncintisana silungele ukwanda kwemakethe yabathengi embonini, nobuchwepheshe obuningi kanye nokugxila ekunciphiseni izindleko, okungakhuthaza nokukhula okuqhubekayo kosayizi wemakethe yemboni ye-LED.
Izinguquko ze-landscape zesikhathi esizayo azikaziwa, kepha ngesikhathi samanje semikhiqizo yokubonisa ehlukahlukene futhi ukuncintisana ngombono wabathengi, imboni yokubonisa ye-LED ephelele isadinga ukudingidwa: Yiziphi ezinye izici okufanele zidingidwe yini imikhiqizo engavulwa kangcono imakethe yekhaya? Kufanele sisondele kanjani emakethe yabathengi? Kwabakhiqizi besikrini esiholwayo, ngaphezu kokubheka izinzuzo zabo zobuchwepheshe, kungadingeka futhi bacabangele ukunwebeka nokwanda emasimini amaningi.
