中小尺寸液晶面板（LCD）巨擘 Japan Display Inc（JDI）28 日發新聞稿宣布，已研發出視為次世代面板的「Micro LED 面板」產品，並預計 2019 年 12 月 4~6 月於日本千葉市幕張展覽館（Makuhari Messe）舉行的第 29 屆液晶／OLED／感測器技術展「FINTECH JAPAN 2019」展示試作品。
......
日經新聞、路透社等多家日本媒體報導，JDI Micro LED 面板預估將應用於車用產品等用途，關於量產時間，JDI 研發負責人於 28 日表示，「（量產時間）還未定，但希望能早期導入量產」。據報導，JDI 考慮利用日本國內的工廠量產 Micro LED 面板產品，且據 JDI 表示，量產時產品尺寸預估會擴大至 10 吋左右。

咁快手，唔通同sony合作？ppi做到幾多？
成日話無錢，原來同時研發緊lcd, oled, micro led

Micro led 量產嘅時代終於來臨

到時就有Samsung quantum dot qled series vs JDI 嘅Micro led display

不論勝負結果如何得益嘅都係消費者

即系中國所有panel廠都已經玩完，因為仲系度投資起緊OLED廠
連OLED良率都未ok

另外即系系microLED上而家JDI走得最前??
之前都聽過Samsung發布超大尺寸的microLED
台灣ともだち都發布過細尺寸的microLED
而Apple之前系台灣的microLED研發中心都有新聞

都未量產
岩岩出都一定好Q貴
oled點會冇巿場

等中國D OLED廠起好，良率提升至到一定水平的時候應該都要1.5-2年，到時microLED都成熟
而且中國系microLED上無甚麼進度

另外OLED上，日本JOLED已經發布印刷式OLED，成本比蒸鍍更低

因為Micro LED其中一個關鍵技術 巨量轉移

而巨量轉移係微機電系統(MEMS)範疇
大陸欠缺 呢方面既技術

回覆 6# skywalker167
台日韓要micro led都要2023,民用2025都偷笑。而且就算可以民用化，都會電視果類大panel行先，因為micro led要小型化好難，移動裝置依然會繼續用oled。等micro led全面取代oled睇怕都2027。

研發到件同量產係兩回事, 真係出左又平民價先算

查實

Micro LED 同 OLED 技術上有乜分別 ?

今日又有關於JDI microLED的新聞
今個星期將於fintech japan 2019 展出
1.6"的microLED module，可以用呢D module砌出大尺寸的microLED panel??

Japan Display Inc. (JDI) announced this week that it has completed development of its first Micro LED module. The prototype of the Micro LED module, which is a potential building block for next generation displays and TVs, offers a 265 PPI pixel density. JDI will be demonstrating the module at Fintech Japan 2019 later this week.

JDI’s Micro LED display prototype is a square module with a 1.6-inch diagonal, and offers a resolution of 300×300 pixels along with a maximum brightness of 3,000 nits. The prototype uses gallium nitride LED chips developed by glo (a Micro LED pioneer) and JDI’s LTPS backplane.

As part of the development process for Micro-LED displays, the hope is that display makers can assemble full-sized displays by building them out of individual modules such as JDIs. A modular approach not only offers more control over yields (as opposed to having to fail a full-sized panel over a flaw), but it would also allow manufacturers to easily support multiple resolutions and aspect ratios just by changing the number of modules. That said, being able to produce commercial panels in volume is still years off, and for now Japan Display has made significant progress just in completing their prototype module.

Micro LED technology is a promising candidate for higher-end displays and television that will be available three to four years down the road. The technology has virtually all the quality advantages that OLED has to offer (over LCD), including individually-controlled LEDs, high contrast, fast response times, and wide viewing angles. But equally important, it does not come with the major disadvantages that OLEDs are known for, such as off-axis color shifting and aging-related burn-in. There are many small companies working on Micro LED technology, but so far only a handful of actual displays/TVs manufacturers have showcased their Micro LED prototypes, and only two of them have started to commercialize this technology on a very small scale.

另外與此同時 BOE亦有新聞話會將OLED產能提升超過3倍....
由於LCD供過於求.....
https://www.anandtech.com/show/1 ... on-of-amoled-panels

BOE has outlined a new set of aggressive plans to expand production of AMOLED display panels for mobile devices next year. The company has reasons to be optimistic as it is adding two AMOLED production lines to its fleet, yet their ramp to full capacity is something that remains to be seen.Meanwhile the company has also noted that LCD panel supply is outpacing demand, which makes AMOLED a much more lucrative market at this time..

At BOE’s annual Innovation Partner Conference last week, Chen Yanshun, chairman of the company, said that the company would more than triple production of AMOLED display panels for smartphones (and similarly-sized devices) as early as next year, allowing it to ship upwards of 70 million units. The aggressive goals come as the company is in the process of greatly expanding its manufacturing capacities.

BOE started production of AMOLED panels for mobile devices in October 2017 at its 6th Generation plant in Chengdu, Sichuan province. This factory supplies displays to more than 10 smartphone makers, including Huawei, Oppo, and Vivo. At present, this is the BOE’s only fully-ramped AMOLED line.

The company’s second 6th Generation AMOLED plant in Mianyang, Sichuan province, started mass production of panels in July 2019. The facility yet has to ramp up to its full capacity and it is unclear how many panels it is set to make this year. Meanwhile, BOE says that it will produce around 20 million AMOLED panels this year.

BOE started construction of its third 6th Generation AMOLED manufacturing line in Chongqing last year, so expect it to start production sometimes in 2020, taking time to ramp up to peak production.

Once all three of BOE’s AMOLED production facilities are fully ramped, should be able to get close to their goals. Though whether they can hit (and sell) 70 million panels a year is definitely an ambitious target. But even if they don't hit 70 million, such an aggressive expansion of AMOLED production capacities will still be very welcome in the market, as the additional capacity will help to further push down display prices.

日本70吋賣8萬, 大陸70吋賣8千, 你覺得有可能玩完咩

咪玩啦，JDI 而家連OLED 都未真係量到產
仲要話上一浸管理層做假數
佢如果可以跳過OLED 直去microLED 晚
既
仲有一線生機
但如果要同BoE 鬥OLED 既
下場仲慘過SHARP 同 LG
