Conclusion As DePIN technology continues to evolve, we can expect to see its transformative effects ripple across a wide range of industries and communities. While the full extent of DePIN’s potential remains to be seen, it is clear that this innovative technology holds the promise of transforming the way we interact with and shape the physical world around us. As we continue to explore and refine DePIN, we can look forward to a future where our built environment is more responsive, efficient, and aligned with the needs of both people and the planet.

5/13(月)の決算発表時に今後のスケジュールと見込み等の発表に期待しています。 Brighter, low-energy OLEDs are going into production this year – but they won’t be coming to TVs just yet Tech Radar Story by Carrie Marshall The best OLED TVs are about to get a whole lot better. A new panel technology known as eLEAP will officially go into production later this year, according to FlatpanelsHD. Although it won't be going into any big-name TVs at first, the new screen technology promises to deliver brightness in excess of 3,000 nits and improved durability, which means that it could make screens last longer, helping to cut down on e-waste. eLeap was developed by Japan Display (JDI), which is a firm that was created by the merger of the display businesses of Sony, Toshiba and Hitachi. And while we first started reporting on it in 2022, it's only just starting to ramp up production with plans to expand this to the mainstream market in late 2024. Although no consumer brands have yet announced plans to use the new tech, the panels are likely to appear in laptops first, with one of the first panels being a 14-inch OLED for portable computers. That'll deliver peak brightness of 1,600 nits, but even brighter panels are imminent. What is eLeap OLED? eLeap – it's an extremely tenuous acronym for "environment positive lithography with maskless deposition, extreme long life, low power and high luminance" – uses light to transfer patterns in the manufacturing of integrated circuits, a process that can deliver increased brightness and increased durability too, which is great news for cutting down on e-waste. This is the first OLED technology to use such a process, and according to Japan Display the production process is currently six months ahead. In the eight months before launch, JDI says it's already achieving production yields of 60%. The higher the yield the more efficient the production and the lower the cost. According to JDI, it will supply eLeap panels "for use in a wide array of end-use applications, including smartwatches and wearables, smartphones, notebook PCs, and automotive displays". TVs are currently conspicuous by their absence, however. That's because the manufacturing capacity isn't there yet to produce larger panels: JDI's plant for that is not expected to be online until 2027.

今年のな 12月からな 茂原でeLEAPの量産に入るらしいけどな その前にな 10月末に蕪湖市との本契約の発表やな 駄目なら茂原に量産ラインを増設するんかな その方が ええような気もするけどな 知らんけど Japan Display to debut alternative eLEAP OLED displays later this year HDTVtest By Mike Wheatley - 23 April 2024 Japan Display has revealed that its much-vaunted eLEAP OLED technology is ready for mass production, and it will launch its first displays ahead of schedule. It’s aiming to deliver its first products by the end of the year, targeting laptops, smartphones and wearable devices initially. The eLEAP OLED technology is an alternative to regular RGB OLED, LG Display’s WRGB OLED and Samsung Display’s QD-OLED, and it has been created by Japan Display, which is a joint venture between Sony, Toshiba and Hitachi’s display panel-making business. The company first revealed eLEAP OLED back in May 2022, making some impressive claims such as its ability to deliver twice the peak brightness of other OLED variants, twice the efficiency and three-times longer lifespans. The key advantage of Japan Display’s eLEAP is its larger aperture ratio, which refers to how much of the space in each OLED pixel can be used to generate light. The larger the space devoted to producing light, the brighter the pixel will be. With conventional OLED displays, the aperture ratio is a mere 28%, but with eLEAP, Japan Display says it has expanded this to 60%. It's not clear how eLEAP stacks up to the most recent generation of OLED displays, however. The term eLEAP is an abbreviation of the tongue twisting technical verbiage “Environment positive, Lithography with maskless deposition, Extreme long life, low power, and high luminance, Any shape Patterning”. It’s the first OLED display that uses photolithography techniques for maskless deposition, which also contributes to the higher brightness and longer lifespan. The company promised to commence mass production of eLEAP displays in 2025, but today’s announcement indicates that it is well ahead of that original schedule. In a statement, Japan Display explained that it first began test production in October 2023 and is now ramping up for eLEAP mass production at its G6 fab in Mobara, Japan, by December 2024. “The production ramp is well ahead of plan: eight months ahead of launch, JDI has already achieved a production yield of over 60%, underscoring that JDI has successfully overcome the key technical hurdles for launch,” the company stated proudly. “JDI will supply eLEAP for use in a wide array of end-use applications, including smartwatches & wearables, smartphones, notebook PCs, and automotive displays.” The G6 fab in Japan is one of a couple that will ultimately start mass producing eLEAP OLED displays. Last year, Japan Display announced it had formed a strategic alliance with a Chinese display maker called HKC, in order to construct what it says would be “world-class eLeap fabs” in China. FlatPanels HD says HKC has since abandoned the project, but Japan Display plans to press on with what will be an 8.7 Generation plant when it comes online. The facility won’t be ready until 2027 at the earliest, but when it is up and running it will allow the company to manufacture much larger eLEAP OLED panels for TVs. Japan Display said one of its first eLEAP products will be a 14-inch display intended for laptops. It will be based on a “single-stack structure” and be able to hit a peak brightness of 1,600 nits. When using a tandem structure, eLEAP can achieve even higher brightness levels that exceed 3,000 nits, the company said. Japan Display has not yet announced any partnerships, so we will have to wait and see which brands choose to adopt the technology.

こっちの方が分かりやすいかしら? 大昔の解説ですが? https://pc.watch.impress.co.jp/docs/column/kaigai/646660.html HBMはThrough Silicon Via(TSV)技術によるダイスタッキングを前提としたメモリ規格だ。 Wide I/O2とHBMの比較 TSV技術によってDRAMとGPUやCPU/SoCを直接続してしまうのが3Dダイレクトスタッキング。それに対して、シリコンインタポーザまたはTSVインタポーザを使って接続する方法が2.5Dスタッキングだ。3Dスタッキングでは、GPU/CPU/SoCのロジックチップ側にもTSVで穴を空ける必要がある。それに対して、2.5Dなら、ロジックチップ側にはTSVの穴を開けなくて済むため、CPUやGPUのメーカーが適用しやすい。 3Dと2.5Dのダイスタッキング技術 シリコンインタポーザは、上の図のようにTSVによるViaが開けられ配線されたシリコンチップだ。インタポーザ上に、CPUやGPUなどのロジックチップとDRAMチップを載せる。どちらも、インタポーザとはマイクロバンプで接続する。DRAMをスタックする場合はTSVでスタックする。インタポーザ自体は通常のバンプでPCBに接続する。
