Japan Display Inc. (JDI) has developed eLEAP, the world’s first OLED technology ready for mass production using maskless deposition and lithography. eLEAP is a breakthrough in display technology that overcomes the weaknesses of current OLED and LCD display technologies.
Currently, fine metal masks (FMM) are the primary method of organic material evaporation for OLED display mass production. eLEAP does not use FMMs – it is a new technology that patterns RGB pixels more precisely.
In combining eLEAP with JDI’s HMO (high mobility oxide) backplane technology, JDI is improving the weak points of OLED displays with respect to peak brightness, lifetime, and power consumption. eLEAP enables designs to be free shape and can manufacture large displays, which is difficult with the conventional FMM method due to the limitations of metal masks. The conventional FMM method for OLED is limited up to G6 glass substrate sizes (c. 1500 mm x 1850 mm), while eLEAP is able to be deployed at G8 (c. 2200 mm x 2500 mm) or larger.
eLEAP is also a GreenTech manufacturing process with low operating costs. The issues with the conventional FMM method include low material usage efficiency in the deposition process, with a significant amount of material waste due to the need for cleaning fluids to remove materials adhering to the FMM during production.
Because eLEAP does not use FMMs, the eLEAP manufacturing process significantly reduces both material usage and waste and CO2 emissions. eLEAP displays are thus more environment positive than OLED displays manufactured via the conventional FMM method.
JDI is already in discussions with customers and has received significant customer interest, with customer demand expected to grow rapidly over time. JDI will start sample eLEAP production this year and increase production volumes going forward. JDI also expects to provide this breakthrough technology to other display companies, driving significant growth for JDI while working to contribute to a sustainable society.
