Japan Display has introduced a new method of manufacturing OLED displays that can double the brightness compared to conventional OLEDs!

It almost reads as if Japan Display (JDI) has struck the holy grail of display technologies. Then eLEAP surpasses the capabilities and possibilities of conventional OLED displays, such as those used in high-end televisions, monitors, smartphones, etc., in virtually every discipline. And all this only by adapting the production process. JDI has managed to arrange the subpixels without so-called fine metal masks (FMM) in OLED mass production.

How is eLEAP changing OLED production?

But what does it exactly mean? The Fine Metal Masks are something like small “muffin cups” in which the organic LED material is evaporated. The metallic border ensures that the materials do not mix/overlap or illuminate neighboring subpixels. With the omission of FMM, there is more space for the OLED material. That’s no less than one, according to JDI “Historical breakthrough in display technology that eliminates the weaknesses of current OLED and LCD displays.”

JDI lets these big words speak for themselves. The application of the RGB pixels is more precise thanks to the new production process, which increases the total area of ​​the sub-pixels. The efficiency of the output brightness as a function of the total area is said to be 60 percent with eLEAP – more than double what conventional OLED displays achieve (approx. 28 percent).

The “Holy Grail” of display technology?

This has two positive effects. An eLEAP OLED display requires much less power for the same brightness as a regular OLED display, e.g. from LG or Samsung. This is particularly interesting for mobile devices. Less power also means the lifetime of the OLED materials increases. This should more than double, in the best case even triple. Finally, the increase in brightness could also be played out without considering the service life. eLEAP should not only double the peak values, but also the average brightness of OLED displays.

Flexible OLED production from 1 to 100 inches

Without the metal masking, production can also be much more flexible. The maximum production size for OLED Grail substrates could be significantly increased, perhaps even to G8 (2,200 x 2,500mm). Almost all conceivable formats and sizes of “eLEAP displays” could be cut from the substrates. From the smallest OLED displays for smartwatches to OLED displays with up to 100 inches and more.

eLEAP can be used in every sales segment, from smartwatches to televisions, monitors, automobiles, VR and much more.

Finally, an eLEAP OLED display can be produced not only more ecologically but also more cost-effectively by eliminating the fine metal masks. The only catch? It will probably be a few more months before the production process is ready for series production. One wants to start with a sample production by the end of 2022 in order to convince potential buyers and third-party manufacturers of the production technology. We are excited and hope that the method presented will soon be used.

Benefits of eLEAP:

  • More ecological and cost-effective production processes
  • More flexible production (size selection + enlargement of substrates)
  • Doubled emission efficiency (eLEAP 60% – conv. OLED 28%)
  • Reduced power consumption with the same brightness (compared to conventional OLEDs)
  • Increased service life due to lower power supply (2x, in the best case 3x)
  • Improved color brightness of eLEAP OLEDs

eLEAP is an acronym and stands for:

eenvironment positive
Llithography with maskless deposition
Extreme long life, low power, and high luminance
Any shape Patterning
