Ngaso leso sikhathi, ubonge iNationStar Optoelectronics, Unilumin Technology, Silan, HC Semitek, Huateng Semiconductor Equipment, Ipas New Materials, Xi Iqhaza nokwesekwa kwamayunithi abambe iqhaza afana noDa Electronics, Zhongqi Optoelectronics, Lehman Optoelectronics, Ringhuecheng, Yinghuecheng, Izinto zokwakha, I-MEAN WELL Power, i-Tecco Chemicals, i-Dahua Co., Ltd., i-Guangjiayi namanye amayunithi abambe iqhaza, futhi iklomelisa amayunithi abambe iqhaza esitifiketini salapho.
Ucwaningo lwe-"Small Pitch LED Research White Paper" lwathatha izinyanga ezingu-9, lwahlola izinkampani ezingu-41, kanti amayunithi angu-14 abambe iqhaza abambe iqhaza ekulungiseni iphepha elimhlophe. UMnu. Cai Jiandong wabelane nabanye bokuqukethwe okuhle ephepheni elimhlophe nabalaleli. Isigaba sokuthuthukiswa esibalulekile sokuboniswa kwe-LED eminyakeni engu-25 edlule, ingqondo yezimboni yokukhuthaza ukuncishiswa kwe-LED display pitch (Pitch), futhi yamemezela ingxenye yokwakheka kwemakethe yesibonisi se-LED, umnikelo wenani lokuphuma kweyunithi yesibonisi se-LED, izindleko zesakhiwo sokuboniswa kwe-LED. , Idatha efana nethrendi yentengo yamadivayisi apakishiwe e-RGB, isikali senani lokukhiqiza lesibonisi se-LED, nencazelo nokuhlaziywa kwe-Mini LED ne-Micro LED.
Ukwengeza, ikhadi lombiko kanye nezitayela zokutshalwa kwezimali zemboni yokubonisa i-LED engxenyeni yokuqala yonyaka nakho kwabelwana ngakho, kanye nobukhulu bemakethe bemibukiso nezinkomfa ezichwepheshile, amathiyetha, ama-TV anosayizi omkhulu nezinye izigcawu zibaliwe, kanye umbono wokuthambekela engxenyeni yesibili nonyaka ozayo.
Ochwepheshe bathi idatha yesikhungo socwaningo lwemboni ikhombisa ukuthi ngo-2019, imakethe yokubonisa i-LED yomhlaba wonke yafinyelela kuma-yuan ayizigidi eziyizinkulungwane ezingama-45.2, lapho imakethe yokubonisa ye-LED encane (≤P2.5) yayingama-yuan ayizigidi eziyizinkulungwane eziyi-17.3, ibalwa ku-38.23%. Ngo-2020, ngenxa yomthelela wobhubhane olusha lomqhele, kuzoba nokwehla kancane kancane ngo-2020, ikakhulukazi ngenxa yokuncipha kwemisebenzi yangaphandle neyezentengiselwano ebangelwe yilolu bhubhane. Ochwepheshe bathi i-Industrial Research Centre ilindele ukuthi isikali sokuboniswa kwe-LED emhlabeni wonke sehle ngo-8% ngo-2020 siye ku-41.6 billion, ngokubonisa izikhala ezincane Izinga lokuncipha kwesikrini liphansi kancane, lingaphansi kuka-5%.
The global zezikrini zokubonisa ze-LED zizoqala ukusimama kancane kancane engxenyeni yesibili ka-2020. Nakuba zisabhekene nokungaqiniseki okukhulu, kulindeleke ukuthi zibe endleleni yokukhula ngo-2021. Ngokuthuthukiswa kobuchwepheshe be-Mini LED direct display (Mini RGB) , ukufakwa ( Okufana namathiyetha wamabhayisikobho, osayizi abakhulu be-TV, izinkomfa zezinga lebhizinisi, imfundo, njll.) ukungena, ochwepheshe bathi isikhungo sokucwaninga semboni ye-LED imboni yokubonisa kulindeleke ukuthi idlule inani eliphumayo lamayuan ayizigidi eziyizinkulungwane eziyi-100 ngo-2025, izinga lokukhula elihlanganisiwe ka-2020-2025 idlula u-21%, isibonisi se-LED esinephimbo elincane Ingxenye yesikrini nayo izokhuphuka isuka ku-38.23% iye ku-56.11%.
Kuze kube manje, i-"2020 Expert Point·Small Pitch and Mini LED Advanced Application Conference kanye neNkomfa Yempumelelo "Yocwaningo Lwe-LED Yokucwaninga" Yempumelelo" iphethe ngempumelelo. Nakuba kuyilolu suku kuphela, lesi yisenzakalo esigcwalisekayo nesingenakulibaleka. Isibonisi esisha se-Mini/Micro LED sizoletha ukubunjwa kabusha kwesakhiwo semboni. Ukuthuthuka kwephimbo elincane kanye ne-Mini LED kuzoba uhambo olugcwele ithemba nezinselele, kodwa umqondo womsebenzi onikezwe i-LED nokubonisa abantu ngokomlando uzosikhuthaza ukuthi sinqobe ubunzima obubodwa! Akungabazeki ukuthi isibonisi se-LED sizoletha ukukhanya okukhanyayo kusasa.
