OLEDs, which were once limited by cost issues and have been difficult to get larger applications, have begun to see the dawn. Many international manufacturers have also launched their own OLED lighting products, and the application of large-size TV backlights has begun to break through. .
Recently, Osram, an international lighting manufacturer, announced that it has signed a cooperation and evaluation agreement with Universal Display, which has rich OLED-related technologies. Under this agreement, OSRAM will begin to produce solid-state lighting products using the patented PHOLED TM fluorescent OLED material from Universal Display.
At the end of 2015, Han Min, Director of Lighting Solutions Division of Osram Greater China, said that Osram will adhere to three focuses in the transformation process, one is the product intelligence of German brands, and the other is huge innovation every year. - For example, OLED automotive lighting, innovation in business capabilities, business services, and products.
It can be seen that OSRAM has great confidence in OLED lighting applications.
One of the material advantages of OLEDs is the flexibility of the design. Applying such an extremely thin material to an elastic substrate, the OLED can be fabricated into products of various shapes. OLED products can be completely transparent and can be illuminated on both sides.
This feature of OLED materials will open up new design boundaries for lighting technology and bring consumers a new lighting experience. Not only that, OLED features include: easy control, low operating temperature, low operating current, instant start, dimming and no flicker, no glare, no noise and low UV radiation.
According to statistics, OLED lighting is expected to grow at an average annual growth rate of 75%, and will reach $2.4 billion in 2020. By 2023, the total output value of OLED lighting is expected to soar to the highest value - $6.7 billion.
Danny Tack, head of Philips TV business, commented on today's TV industry: "3D has not been saved, neither can bring any novel experience, nor attract consumers. Now the best-selling 4K TV, but the future is OLED. â€
Danny Tack's words are crucial: "If it was a year ago, you would find that OLED TVs are nearly three times more expensive than high-end 4K LCD TVs. But now, the price of OLEDs is declining and will eventually dominate the market. Because of the inherent nature of OLEDs. The characteristics are better than liquid crystal, especially its black level and contrast. Although there are many problems with OLED at present, if we don't lay out OLED now, we will be left behind by other competitors after one or two years. ."
LG Chem is selling its OLED lighting business to LG Display for $142 million. In the future, LG Display will focus on automotive applications for OLED lighting.
Compared with LED, OLED illumination has better color rendering, and the thickness of luminescent material is less than 1 mm. The heat generated can be directly touched by hand without glare, and the human eye can directly look at it. From the perspective of product design, OLED lighting is a surface light source, no reflectors and hoods, and no LED point light source, subject to the limits of the socket.
In the future, with the mass production of OLED lighting, the yield will continue to increase, while the demand for display and lighting will continue to increase, and the cost of OLED lighting will continue to decrease, and future applications will become more and more common.
