JDI’s breakthrough OLED “eLEAP” technology caught Samsung’s attention due to its longer lifespan, higher peak luminance, and no burn-in issues.


Samsung Display is interested in a technology for producing OLED panels that does not require the use of masks. A senior Samsung executive recently visited its US equipment supplier Applied Materials headquarters to discuss JDI’s eLEAP technology; a technology that could be ideal for future Apple devices.

Developed on the back of JDI’s design and process know-how accumulated over many years, eLEAP solves the burn-in and short life problems of conventional FMM OLEDs and realizes higher aperture ratio, higher peak luminance and higher resolution, while maintaining the properties of conventional FMM OLEDs in terms of finesse, lightness, high contrast and fast response times, according to JDI documentation discovered by Patently Apple. It could be an ideal OLED upgrade for Apple devices in the future.

3 eLeap Advantages

According to a supply chain report from The Elec, Samsung Display and other OLED panel makers are currently using fine metal masks, or FMMto deposit red, green and blue organic materials in the form of vapor on the substrate.

These masks are difficult to manufacture, and their quality determines the performance of OLED panels, which was the case with OLED Gen 6 panels (1500x1850mm). The Japanese company Dai Nippon Printing is the main supplier of FMM.

The issue of FMM is sensitive for Samsung Display because their quality will determine the performance of OLED Gen 8 (2200x2500mm) panels, which have not yet been marketed. If there’s a more convenient way to make the signs without the masks, there’s no reason the South Korean billboard maker shouldn’t take it.

Still, JDI is a rival panel maker, and that’s probably why Samsung Display asked about eLEAP indirectly to Applied Materials, which supplies deposition machines to the Japanese company.

Sources said there are currently several views inside Samsung Display on eLEAP: some want to be open to the technology while others want to prevent its competitor from commercializing the technology. Source: The elect.

If Apple’s display team considers this to be a next-generation OLED display technology that they want to use for some future devices, Samsung and LG Display will have to prepare to meet the needs of Apple’s display. ‘Apple.
