Lõuna-Korea meedia Thelec teatas 6. aprillil tööstusallikate kaudu, et China Boe kavatseb ehitada 8,6 põlvkonna (2250 x 2600 mm) orgaanilise valgusdioodi (OLED) tootmisliini IT jaoks oma B16 tehases Chengdus, Sichuani provintsis. igakuine võimsus on 15 000 (15 000) tükki, mis on mõeldud masstootmiseks 2024. aasta lõpuks.
In response to investors' questions, BOE said today (April 6), "Our plan in this respect is based on full communication with customers on the basis of pre-research, the project team is currently carrying out strategic, market, technical, financial and other aspects of the evaluation, is still in active discussion. Also, the design capacity is definitely not 15K/ month, which is uneconomical."
Kuna Apple kavatseb rakendada OLED-i IT-toodetes, nagu iPad (tahvelarvuti) ja MacBook (sülearvuti), on 8. -põlvkonna (8,5/8,6 põlvkond) IT jaoks mõeldud OLED-tehnoloogia esile kerkinud järgmisena{{6} }põlvkonna lahinguväli. Ökonoomsem on toota 10-tollist või suuremat IT OLED-i 8G juhtmega kui olemasolevat 6g (1500x1850mm) traati. 13,3-tolliste paneelide puhul suudab kuues põlvkond teha 48 tükki, kuid 8,5 põlvkond (2200x2500mm) 96 tükki, mis kahekordistab võimsuse.
Samsung Display and LG Display are both currently planning to produce the first iPad OLED in the 6th generation line, but they are already working on the 8.5 generation OLED technology for Apple'S IT products, with mass production expected around 2024.
Boe kavatseb 8.6 põlvkonna OLED-sadestamise tehnoloogiana kasutada pool{0}}lõiget horisontaalset sadestamist, öeldakse aruandes. Olemasolev 6. põlvkonna OLED-tehnoloogia, mida kasutatakse peamiselt nutitelefonide OLED-i tootmiseks, kasutab samuti pool-horisontaalset sadestamise meetodit.
LG Display arendab 8,5-gen pool-horisontaalset sadestamise tehnoloogiat ja Samsung Display arendab 8,5-generatsiooni täis-lõike/vertikaalse sadestamise tehnoloogiat, kuid 8,5-geni poollõike/horisontaalse sadestamise tehnoloogia kui kaherajaline tehnoloogia on mõjukam.
Boe is said to be in contact with Japan's Canon Tokki, but has not yet asked Cannon to secure slots for the evaporator. (Slot is a verbal request prior to the signing of a Letter of Intent to purchase (LOI) and a formal order (PO))
Boe plans to take the lead in testing OLED technologies for IT products in other production lines before building the 8.6 generation OLED line. For example, the realization of the "double stack series" structure is to stack the red (R) green (G) blue (B) luminous layer into two layers, compared with RGB luminous layer stacked in one layer of the "single stack" mode, two stack series makes the screen brightness increase twice, product life extension four times. Apple prefers two-layer oleds in series for IT.
Eelmise aasta lõpus muutis BOE chongqing B12 tehase III faasi rakenduse nutitelefoni, IT ja sõidukite jaoks OLED-i vastu. Esialgu, nagu faasid 1 ja 2, on ka 3. faasi tootmisliini eesmärk toota 6. põlvkonna paindlikke OLed-e, peamiselt nutitelefonidele. 10-tollise iPad OLEDi tootmiseks on aga vaja teistsugust tehnoloogiat kui senine 6,1-tolline iPhone OLED, sest protsessid nagu orgaanilise materjali sadestamine muutuvad ala suurenedes paratamatult raskemaks.
Power consumption can also be reduced by applying two-layer series OLED to smartphones. Boe also plans to produce dual-laminated series OLED for smartphones in the second half of the third year at its B7 plant in Chengdu, sources said. B7 used to produce OLED for Apple's iPhone, but utilization of B7 declined as BOE's B11 line in Mianyang, which had planned to be dedicated to the iPhone, began normal operation.
However, Samsung Display and LG Display are likely to build 8.5-generation OLED lines for IT as soon as possible. Samsung Display has been evaluating 8.5-generation full-cut vertical deposition with Japan's Ulvac last year, and LG Display has been evaluating 8.5-generation OLED deposition for IT since December at partner Sunic System's Paju plant in Gyeonggi Province.
