Njengoba sazi, isibonisi se-COB (Chip-on-board) sinezinzuzo zokugqama okuphezulu kakhulu, ukukhanya okuphezulu, kanye ne-gamut yombala obanzi.
Enqubweni yokuthuthukisa ukusuka kwiphimbo elincane ukuya ekubonisweni kwephimbo elincane, iphakheji ye-SMD yasekuqaleni kube nzima ukweqa umkhawulo wephimbo lamachashazi amancane, futhi kunzima nokuqinisekisa ukwethembeka nokuvikelwa okuphezulu.Isibonisi se-Micro pitch sidinga ubuchwepheshe be-COB ukuze kusekelwe ukuthuthukiswa kwesibonisi sephimbo esincane esinokuphakama kwephikseli okungaphansi kuka-P1.0mm.
Isibonisi se-COB samukela inqubo yokupakisha ye-flip-chip, enendlela emfushane yokukhipha ukushisa futhi evumelana kakhulu nokushisa uma kuqhathaniswa nesibonisi esivamile sobuchwepheshe be-SMD.
Ngokukhula okuqhubekayo kobuchwepheshe bokwelapha obungaphezulu kwe-COB kanye nobuchwepheshe bokuhlanganisa ama-chip, imikhiqizo yokubonisa i-LED esebenzisa ama-flip-chip chips amancane kunama-microns angu-100 izoba imikhiqizo ebonisa ithemba kakhulu esikhathini esizayo.
I-P0.9 COB Mini/Micro LED Display ingumkhiqizo ovuthiwe, okhiqizwe ngobuningi
Ngo-2019, umthamo wokukhiqiza ngobuningi wezibonisi ezingaphansi kuka-P0.9 usalinganiselwe.Ngakolunye uhlangothi, isidingo semakethe silinganiselwe, futhi amandla okusekela ochungechunge lwezimboni nawo awanele.
Ngo-2021, ngokuthuthuka kobuchwepheshe bokupakisha, ukwenziwa ngcono kokusebenza kahle, kanye nokuncipha ngokushesha kwezindleko zama-chips e-LED, njll., isidingo semikhiqizo engaphansi kuka-P1.0 kancane kancane sizoba imakethe ethandwayo, futhi imikhiqizo ye-Mini LED izophinde ingene phakathi imakethe yezinga eliphezulu ukuya emakethe ephakathi kuya kwephezulu, kusukela ekubonisweni kochwepheshe kuya ekubonisweni kwezentengiso bese kuya ensimini yabantu, ishintshe isinyathelo ngesinyathelo.
Ngo-2022, ngokuya ngefomu lokupakisha, noma ngabe i-COB, i-4-in-one, noma i-2-in-one, akuyona inkinga ngokuhlinzekwa kwemishini ye-diode engu-P0.9mm, futhi kokubili umthamo wokukhiqiza kanye nesivuno kungaba okuqinisekisiwe.
Kodwa-ke, ngenxa yezizathu zamanani, kusukela emakethe yamanje ye-pitch encane, imakethe yemikhiqizo ye-P0.9 isagxile kakhulu kwezinye izingqungquthela, amaphrojekthi wokuyala kanye nokuqapha amakamelo kahulumeni noma amabhizinisi amakhulu kahulumeni, kanye ne-P1.2- I-P1.5 iseyimakethe ye-small-pitch market..
Kodwa lesi simo siyathuthuka, futhi izimo zohlelo lokusebenza lwemikhiqizo eqondile ye-P0.9 Mini zikhula njalo.
I-pitch ezungeze isibonisi se-P0.7 se-LED izoba yisizinda sesizukulwane esilandelayo.
I-P0.7mm ingathola ukulungiswa kwe-4K kwesikrini esingu-100-200 amayintshi
Usayizi ophakathi kwamayintshi angu-100-200 iyimakethe enkulu engase ibe khona yezicelo zokuboniswa kwephimbo elincane.
Ngenxa yokuthi imakethe engaphezu kwama-intshi angu-200 isivele igcwele izibonisi ze-LED ze-P1.2 ~ 2.5mm zendabuko ezincane, futhi usayizi omncane kakhulu imikhiqizo ye-LCD TV engu-98-inch, inani elincane lamanje lingaphansi kuka-3,000 USD, kanye nesibonisi. umphumela nawo muhle uma kuqhathaniswa.I-fine pitch display LED inzima ukuncintisana ne-LCD emakethe engu-98-intshi.
Nokho, usayizi wokuboniswa wesikrini se-LCD kunzima ukweqa umkhawulo wamayintshi angu-100.Izimbangi zendabuko zemibukiso engu-100-200-intshi ngokuyinhloko ziyizibonisi—nokho, izikrini ezinkulu ze-LED ezinephimbo elihle zisebenza kangcono ngokubonakalayo ngaphansi “kwezimo zokukhanya” ezikhanyayo.
Iningi lezimakethe ezingu-100-200-intshi zifaka amagumbi enkomfa, ezohwebo, ezokukhangisa, nezinye izimo, ezidinga izimo zokukhanya ezingcono.
Futhi emakethe ye-100-200 inch, izibonisi ze-LED ze-pitch encane nazo zibhekana nesidingo sokuqhathanisa ukulungiswa kwe-PPI nezibonisi ze-LCD.
Ngoba uhlelo lokusebenza lwe-100-200-inch luhambisana nebanga eliseduze lokubuka lamamitha angu-3-7, noma ibanga lokubuka eliseduze.Ibanga eliseduze lokubuka liqinisekisa umphumela wekhwalithi yesithombe, kodwa futhi lidinga “ukulungiswa okuphezulu kwe-PPI”, okungukuthi, kudinga ukuphakama kwephikseli encane.
Kalula nje, ama-LCD we-75-98-inch asevele azuze ukulungiswa kwe-4K;ukulungiswa kwezikrini ze-LED ezinencazelo ephezulu engu-100+ akukwazi ukuba kubi kakhulu.
Inkomba ye-P0.7 inganikeza ukulungiswa kwe-4K ku-120-intshi+, okuyisinqumo ncamashi sezinhlelo zokusebenza zamanje ezivamile zomsindo nokubukwayo futhi sikhulu kune-LCD engama-intshi angu-98.
Mayelana nalokhu, isifaniso siwukuthi ukuphakama kwephikseli kwamanje kwama-TV e-LCD avamile kuphakathi kuka-0.3 no-0.57 mm.Kungabonakala ukuthi isikhala sesikrini se-LED esinephimbo elincane esingu-P0.7 mm singaxhuma kangcono umuzwa wohlelo lwamamonitha e-LCD, futhi sinikeze imikhiqizo ehlukanisiwe ngosayizi abakhulu bangamayintshi angu-100-200.
Ngakho-ke, kusukela esidingweni semakethe sosayizi nesinqumo, kungabonakala ukuthi i-P0.7 izoba inkomba yesizukulwane esilandelayo esijwayelekile sezikrini ze-LED ze-micro-pitch.
Kodwa ukuthuthukiswa kwemakethe yokubonisa ye-P0.7 100-200 inch kudinga amanani angcono manje.Mayelana nalokhu, ama-LED anephimbo elincane aya ngokuya ezuza imiphumela ngokuqongelela ulwazi oluqhubekayo kanye nokuthuthukiswa kwenqubo yomkhiqizo kancane kancane.Ikakhulukazi eminyakeni emithathu edlule, imikhiqizo ye-P0.9 izuze impumelelo ethile emakethe ephezulu, futhi intengo yehle cishe ngama-30%.Abahlaziyi bezimboni bakholelwa ukuthi imikhiqizo engu-P0.7 kulindeleke ukuthi ibe nenani elifanayo nemikhiqizo yangaphambili engu-P0.9.
Imboni ilindele ukuthi eminyakeni emibili ezayo, uchungechunge lwemboni ekhuphukayo lwezibonisi ze-LED ezihlanganisa ama-mini LED chips, njll., luzothuthukiswa kakhulu, futhi izinga lobuchwepheshe bomkhiqizo kanye nenqubo yokukhiqiza nakho kuzothuthukiswa kakhulu.Imakethe yezimboni ibhekene nomjikelezo Amathuba okunciphisa amanani.Lesi futhi "isikhathi esikahle" sokuhlelwa kwesizukulwane esisha semikhiqizo ye-"P0.7 pitch".
Uhlelo lokusebenza lwe-100-200-inch "isimo esisha" esijwayelekile esihlola ubuchwepheshe bemboni kanye nokulawulwa kwezindleko.
Yiqiniso, izinkampani ezihlukene zizophinde zenze izinguquko ukuze zigqamise izinzuzo zazo zomkhiqizo: isibonelo, ukuze kuncishiswe izindleko nobunzima, abakhiqizi bangahlinzeka ngemikhiqizo engu-136-inch 4K ngephikseli enkulu kancane;noma unikeze ukulungiswa kwe-4K ngemikhiqizo yosayizi emincane, njenge-Samsung The Wall isebenzisa iphimbo elingu-0.63mm.
Yiziphi izinselelo ze-P0.7 pitch display?
Izindleko eziphakeme
Okokuqala yizindleko.Kodwa akuyona inselele enkulu kunazo zonke.
Lokhu kungenxa yokuthi i-P0.7mm kufanele ibe isibonisi esiphezulu, futhi yilawo makhasimende afuna ukusebenza njengokubalulekile.Lokhu kufana nanoma yisiphi isizukulwane semikhiqizo ye-LED ye-pitch encane "esikwa emakethe ephezulu" futhi ngokushesha ithole ukuqashelwa kwemakethe.Ngokombono wezindleko, akunzima kakhulu ukuthi izibonisi ze-P0.7 ziqale ukwanda emakethe esezingeni eliphezulu ekuqaleni.
Ubuchwepheshe bokukhiqiza obungakavuthwa
Uma kuqhathaniswa ne-P1.0, inani lezingxenye endaweni yokubonisa yeyunithi ye-P0.7 liphindwe kabili.Kodwa-ke, nakuba kungenzeka ukuthi uzuze isipiliyoni sobuchwepheshe esiqoqwe yimikhiqizo yangaphambilini ye-P0.9-P1.0, kudinga nezinselele ezintsha ebunzimeni obungaziwa.Imboni isesigabeni sokuqala sobuchwepheshe obuvuthiwe ukuze ikhiqize ngokuphumelelayo imikhiqizo yokubonisa engu-P0.7mm.
Iphimbo elihlukile kancane, alikho izinga
Ngaphezu kwezinselelo zobuchwepheshe zezindleko nenqubo yokukhiqiza, enye inselele yemikhiqizo ye-P0.7 ukuthi ukuhlukaniswa kwezikhala kunzima ukulinganisa.
Uhlelo lokusebenza oluyi-100-200-intshi luvamise ukuba "isikrini sakho konke-kokunye" kunokuba iphrojekthi ehlanganisayo, okusho ukuthi izinkampani zesikrini esikhulu se-LED zidinga ukuthola "izidingo zosayizi wohlelo lokusebenza" ezijwayelekile kakhulu futhi zizihlanganise namandla obuchwepheshe ukuze yakha into efana nale: 4K resolution , 120 amayintshi, 150 amayintshi, 180 amayintshi, 200 amayintshi kanye nabanye osayizi amayunithi fixed, kodwa pixel pitch ukuminyana kwehlukile.
Ngenxa yalokho, amayunithi abonakala afanayo angu-110/120/130-intshi adinga ukusebenzisa “isakhiwo sobuchwepheshe benqubo eguquguqukayo” esiguquguqukayo nezinga le-P0.7 le-pitch.
Ukubhekana nokuncintisana okuqondile okuvela kuma-LCD okuhweba omdabu noma abahlinzeki be-projection
Ukwengeza, emakethe yokubonisa i-LED ephakathi kwama-intshi angu-100-200, izinkampani zesikrini se-LED ezine-pitch encane nazo zidinga ukubhekana nezinselele zokuncintisana ezivela ezinkampanini ezisebenzisa izikrini ezinkulu ze-LCD zezentengiselwano njengemikhiqizo yazo.
Emakethe ye-LED ye-pitch encane yangaphambili, izinkampani zesikrini esikhulu ze-LED zaziqhudelana nontanga yazo, kodwa manje zidinga ukwandisa ububanzi bokuncintisana cishe kuyo yonke imakethe yokubonisa ezentengiso.Ize ibhekane nengcindezi yokuncintisana yemikhiqizo ye-TFT-MINI/MICOR LED eyethulwe yi-BOE ne-Huaxing Optoelectronics.
