Flexible OLED display technology makes future electronic products full of possibilities

Including EMS vendors, well-known academic institutions, and the US Department of Energy, in the recent past, allied to the display technology of the next generation of electronic devices, or to invest in new development work. These efforts are expected to further accelerate the expansion of advanced display technology.

Earlier, Sanmina-SCI signed an agreement with solar inverter manufacturer KACO new energy Inc.; MIT showed solar panels that could be printed on paper; and in Roches eMagin at the University of Technology is working with the US Department of Energy to develop the next generation of organic light-emitting diodes (OLEDs).

OLED is a technology that can develop displays on flexible substrates. Proponents of OLED displays promise that one day, consumers will be able to carry a solar-powered display that can be rolled up wherever they are, and that they may be about the size of a cigar.

This is definitely possible. OLEDs have been widely used in smartphones, digital cameras and other electronic products. OLEDs require little or no backlighting and can be sprayed onto glass, plastic or other substrates. OLEDs can be developed with flexible displays and are more suitable for bright sunlight, because OLEDs do not require a light source unlike other display technologies.

But as of now, the adoption of OLED displays still has some limitations, because they are still mostly used on small screens. However, some companies, including eMagin, have been working to improve the manufacturing technology of OLEDs, hoping to make them suitable for large-size displays. Another obstacle to the popularity of OLEDs is that OLEDs require luminescent materials.

Andrew G. Sculley, president and CEO of eMagin, said that while OLEDs offer more efficient, brighter, and faster electronic displays, about 80% of the light is wasted. Therefore, in cooperation with the US Department of Energy, it will be possible to significantly improve the luminous efficiency of equipment by developing a technology that uses nanoparticle based on plasmon-scattered light.

The better news is that OLEDs are likely to be powered by solar energy. MIT researchers showed a few solar panels that could be printed on paper. It is reported that this paper photovoltaic array is constructed by an oxidizing chemical vapor deposition process at temperatures below 120 °C. Not only ordinary uncoated paper, but even cloth or plastic can be used. Researchers at MIT printed the solar cell on a layer of PET plastic and folded it 1,000 times and found it still working.

It is indeed feasible to develop a flexible, solar-powered OLED display. However, mass production capacity is also indispensable. EMS Sanmina-SCI is working with inverter manufacturer KACO to reduce the manufacturing costs of solar powered products.

In addition, Sanmina-SCI has set up a core team for new products and established a new dedicated production line for design assembly analysis, designing customized tool sets, establishing detailed documentation, and creating a new independent global supply chain. Logistics support system.

Display technology is becoming the key to all electronic products, including Apple, and is also working to consolidate its iPad's display component sources. OLEDs are a technology that can help current display manufacturers overcome the power consumption challenge. In the future, OLED technology is likely to change the rules of the game, allowing electronics manufacturers to develop new products in combination with power savings, flexibility and strong manufacturing capabilities.
