Abakhiqizi baseTaiwan naseKorea basebenzela ukunqoba izithiyo zemigwaqo zezobuchwepheshe nezihlobene nezindleko kuma-Micro LED displays...
Selokhu kwethulwa isibonisi esikhulu sika-Sony esiyimodyuli ye-Micro Isibonisi ngo-2017, ezinye izinkampani, okuhlanganisa i-Samsung ne-LG, zenze inqubekelaphambili ngokulandelana ekuthuthukisweni kwe-Micro LED, okuphinde kwadala umsindo omkhulu ngamandla obuchwepheshe emakethe yokubonisa enosayizi omkhulu, ngokusho. ophenyweni lwakamuva lwe-TrendForce.
Ama-TV e-Emissive Micro LED kulindeleke ukuthi afike emakethe phakathi kuka-2021 no-2022. Noma kunjalo, izinselelo eziningi zobuchwepheshe kanye nezindleko zisazoxazululwa, okusho ukuthi ama-Micro LED TV azohlala eyimikhiqizo esezingeni eliphezulu okungenani ngesikhathi sobuchwepheshe. isigaba sokuqala sokuhweba.
I-TrendForce ikhombisa ukuthi ubuchwepheshe be-Micro LED cishe buzoqala ukungena emakethe ngezinhlelo zokusebenza ezimbalwa, okuhlanganisa amadivaysi e-AR afakwe ekhanda amancane, okugqokekayo njengamawashi ahlakaniphile, imikhiqizo esezingeni eliphezulu efana nezibonisi zezimoto, kanye nemikhiqizo ye-niche efana nama-TV asezingeni eliphezulu kanye imibukiso yezentengiso enosayizi omkhulu. Ngemuva kwaleli gagasi lokuqala lemikhiqizo, ubuchwepheshe be-Micro LED buzobona ukuhlanganiswa kancane kancane kumathebulethi anosayizi omaphakathi, amakhompyutha wezincwadi, kanye neziqapha zedeskithophu futhi. Ikakhulukazi, i-Micro LED izobona amandla aphezulu kakhulu okukhula emakethe yokubonisa usayizi omkhulu, ikakhulukazi njengoba le mikhiqizo inomgoqo ophansi wezobuchwepheshe. Imali engenayo ye-chip ye-Micro LED, eqhutshwa ngokuyinhloko i-TV kanye nokuhlanganiswa kwesibonisi esinosayizi omkhulu, kulindeleke ukuthi ifinyelele ku-US $ 2.3 billion ngo-2024.
Abakhiqizi baseTaiwan nabaseKorea basebenzela ukunqoba izithiyo zemigwaqo zezobuchwepheshe nezihlobene nezindleko kuma-Micro LED displays.
Kulesi sigaba samanje, iningi lama- Micro LED TV kanye nezibonisi ezinosayizi omkhulu zifaka ukwakheka kwe-LED okungokwesiko kwamaphakheji e-chip e-RGB e-RGB ahlanganiswe nezishayeli ze-matrix (PM). Akukhona nje kuphela ukuthi i-PM ibiza kakhulu ukuyisebenzisa, kodwa futhi ikhawulelwe ngokuya ngokuthi ukuphakama kwephikseli yesibonisi kungancishiswa kangakanani, okwenza ubuchwepheshe be-Micro LED busebenze ezibukweni zentengiso kuphela njengamanje. Kodwa-ke, abakhiqizi bephaneli abahlukahlukene kanye nemikhiqizo yokubonisa eminyakeni yamuva nje bathuthukise izixazululo zabo ze-matrix (AM) ezisebenzayo, ezisebenzisa uhlelo olusebenzayo lokukhuluma nge-pixel futhi zifaka izindiza ezingemuva zengilazi ze-TFT. Ngaphezu kwalokho, idizayini ye-IC ye-AM, uma iqhathaniswa ne-PM, ilula uma kuqhathaniswa, okusho ukuthi i-AM idinga isikhala esincane somzimba somzila. Zonke lezi zinzuzo zenza i-AM ibe yisixazululo esifaneleka kakhulu sama-TV ama-Micro LED anokulungiswa okuphezulu.
Izinkampani zaseKorea (Samsung/LG), izinkampani zaseTaiwan (Innolux/AUO), nezinkampani zaseShayina (i-Tianma/CSOT) zonke okwamanje zibonise izinhlelo zazo zokubonisa ze-AM. Mayelana nomthombo wokukhanya we-LED, i-Samsung ibambisene ne-PlayNitride eseTaiwan ukuze bakhe isibonisi esinombala ogcwele se-Micro LED esakhiwe kusetshenziswa ukudluliswa kwe-semi-mass kwama-chips e-RGB LED. Le nqubo ihlukile endleleni evamile yokukhiqiza isibonisi se-LED, esebenzisa ubuchwepheshe bokupakisha be-chip ye-RGB ye-LED esikhundleni salokho. Ngakolunye uhlangothi, abakhiqizi bephaneli abazinze e-Taiwan i-AUO ne-Innolux baphayona ubuchwepheshe bokuhlinzeka ngombala obuhlanganisa ama-chips e-LED anokukhanya okwesibhakabhaka namachashazi e-quantum noma ama-phosphor e-LED.
Ngakolunye uhlangothi, izindleko zezibonisi ze-Micro LED zincike ekulungisweni kwesibonisi nosayizi we-chip. Njengoba abasebenzisi befuna ukuboniswa kokulungiswa okuphezulu ukuya phambili, ukusetshenziswa kwe-chip ye-Micro LED nakho kuzokhuphuka kakhulu. Ama-TV nezibonisi ze-LED ikakhulukazi zizonciphisa kakhulu ezinye izinhlelo zokusebenza ekusetshenzisweni kwe-chip ye-Micro LED. Isibonelo, isibonisi esingu-75-inch 4K sidinga okungenani ama-RGB Micro LED chips ezigidi ezingu-24 kuhlu lwaso lwe-subpixel. Ngakho-ke, izindleko zokukhiqiza, ezihlanganisa ubuchwepheshe obufana nokudluliswa kwe-semi-mass, nezindleko ezibonakalayo zama-Micro LED chips zizohlala ziphezulu okwamanje.
Ngenxa yalokhu, i-TrendForce ikholelwa ukuthi izinkinga zobuchwepheshe nezihlobene nezindleko zizohlala ziyinselelo enkulu ekutholakaleni kwemakethe kwama-Micro LED TV kanye nezibonisi ezinkulu ze-Micro LED. Njengoba ama-TV ethambekela kumasayizi amakhulu kanye nezinqumo eziphezulu ngokuzayo, abakhiqizi kufanele babhekane nobunzima obandayo kubuchwepheshe be-Micro LED, okuhlanganisa ukudluliswa kwabantu abaningi, izindiza ezingemuva, abashayeli, ama-chips, nokuhlolwa nokukhanda. Uma lezi zingqinamba zobuchwepheshe sezinqotshiwe, noma izindleko zokukhiqizwa kwe-Micro LED zizoncipha ngokuhambisanayo, ukwehla ngokushesha kuyobe sekunquma ukusebenza kwe-Micro LED njengobuchwepheshe bokubonisa obujwayelekile.
