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.

バックプレーン技術のな HMOやなUHMOにも注目やで! Samsung and LG have a new OLED rival Allied forces are gunning for the OLED crown. CLUB386 By Blair Jacobs - 25/04/2024 Samsung and LG have been the forerunners of OLED display technology with little to no competition. Fortunately, there’s a new OLED panel maker in town, and it has its sights set on the number one spot. The company, Japan Display (JDI), and its new eLEAP type of OLED panels will enter production by the end of 2024. JDI announced the tech in 2022 with lofty claims that it developed a “historic breakthrough in display technology.” eLEAP is a new manufacturing process developed via a joint venture between Sony, Toshiba, and Hitachi’s display panel divisions. The process is a cost-effective solution that’s used to create freeform OLEDs that are brighter, more efficient, and long-lasting when compared to the OLED panel types on the market today. The breakdown In comparison, JDI claims its OLED variant offers twice the peak brightness, three times the life span, and twice the emission efficiency. This is achieved by its larger aperture ratio and maskless deposition process. The aperture ratio of an OLED pixel determines how much light it can generate. Typical OLED displays have an aperture ratio of about 28%, whereas eLEAP displays offer up to a whopping 60%. On the other hand, today’s OLED panels are produced using Fine-Metal-Mask (FMM) technology. This method has been the remaining bottleneck for the wider application of OLED displays. FMM is a complex and expensive process because it can only be created in an ambient vacuum environment. It is the main reason why OLED displays are so expensive to manufacture. More defects encountered during the process also lead to less product yield and more material waste. The benefits of eLEAP is in its name: environment positive; Lithography with maskless deposition; Extreme long life, low power, and high luminance; Any shape Patterning. Quite the mouthful and not quite a proper acronym. Nevertheless, removing this complex metal masking process allows JDI to create higher-performance OLEDs at a much lower cost. Should Samsung and LG be worried? Well, not quite yet. The display tech is still limited to its smaller 6-Gen substrate line. JDI initially plans to target smaller products like laptops, smartphones, car displays and wearable tech, at least for now. Thereafter, it can scale the process up to its 8-Gen (2200x2500mm) substrate line, which will allow for larger monitors and TVs. If all goes to plan, this will enter mass production by 2027.
