Osram / Philips / GE / BOE preemptive layout of key technology advantages and prospects of OLED lighting

Organic electroluminescent devices (O LEDs ) are all solid-state, self-illuminating, low operating voltage, low power consumption, and can be used for flexible substrates. They can be used as backlights for flat panel displays (such as liquid crystal displays) or as planar illumination sources. , more and more attention of the majority of scientific research workers. Following the inorganic light-emitting diode (LED), OLED lighting technology has become a research hotspot and focus in the field of semiconductor lighting .

Since 2000, the US Department of Energy has invested $30 million annually in the development of OLED lighting technology. World's three largest lighting manufacturers Philips (Philips), Osram (Osram) and General Electric (GE) also participated in the study OLED lighting applications, in 2010 Japan Lumiotech also launched OLED lighting products. China also has Visionox, Nanjing Dijon Organic Luminescence, and Beijing BOE to actively invest in the R&D and industrialization of OLED lighting panels.

Advantages of white OLED lighting

Compared with LED, OLED has advantages in lightness, flexibility, eye protection, etc. It is especially suitable for indoor large-area illumination, and has attractive application prospects in the future lighting field. In addition, white OLED combined with filter technology can achieve full color display. After nearly two decades of development, the performance and theoretical research of white OLED devices have made great progress, which is close to the luminous efficiency of fluorescent lamps, showing its huge application prospects, and is considered to be the most promising new generation of semiconductor illumination sources.

(1) Surface illumination

Compared with other types of artificial light source technology, O LED technology has unique advantages and is the best illumination source so far. The biggest feature of OLED lighting is that the light source itself is surface-emitting. Existing lighting, including LED lighting, uses point and line sources to illuminate the space. When the surface illumination is required, a plurality of point light sources and line light sources are always arranged together, and a panel-shaped lamp cover is covered on the outside. The use of white OLED technology can directly achieve the illumination of the entire surface, creating the best equipment for a wide range of uniform illumination.

(2) Flexibility

The white light OLED is prepared on a flexible substrate, which can realize a curved light source, can be flexed, and has the characteristics of being not easily broken, which will make the lighting product and the application technology become new and beyond the existing imagination.

(3) Environmental protection

As people pay more and more attention to environmental protection, incandescent lamps and fluorescent lamps are gradually being replaced, LED lighting sources have become the main force, and OLED lighting is expected to become a new lighting technology due to its unique advantages. According to the estimation of Prof. Koji Yuji of the Institute of Science and Technology of Yamagata University in Japan, using OLED lighting, by 2020, it is expected to reduce CO2 emissions by 6.7 million tons and about 2.3%.

Performance of high efficiency white OLED devices

High efficiency, long life and low cost are the key to the industrialization of white light OLED illumination sources. Among them, efficiency reflects the ability to convert electrical energy into light energy. Lifetime reflects its practicality, and cost is the premise of wide application in the market. Considering the choice of materials and the design of the device structure, the combination of fluorescent blue light material and yellow or red and green phosphorescent materials can be used to obtain high efficiency white light emission, combined with light extraction technology, greatly improve power efficiency, and utilize laminated structure. Increasing the stability of the device and obtaining a practical life is the best choice for WOLED. At the same time, thermally induced retardation materials, as a new generation of organic luminescent materials, are receiving attention and rapid follow-up by researchers.

DITUO Plastic Diffuser has many advantages as below:

  • Purifying the air. The Plastic Diffuser generates a large amount of active oxygen anion, which generates a strong reaction with harmful gas molecules in the air, comprehensively removes, and completely eliminates the harm of formaldehyde, benzene and ammonia.
  • the use of safety. Plastic Essential Oil Diffuser can produce 100% of the cool mist can maintain the active ingredients of essential oils, so that the essential oils are more easily absorbed by the body to achieve maximum effect; within 2 seconds can feel the original aromatherapy effect. It is fundamentally different from the traditional heating and burning hot fog method. Its cold fog technology does not damage any components of the Essential Oil , does not cause secondary pollution, and is safer to use.
  • small size. Aroma Diffuser water volume of about 100ml, just add 2-3 drops of essential oil in water to achieve aromatherapy.
  • strong corrosion resistance. Good Air Diffuser is made of special ABS material, resistant to oil, water and chemical corrosion.
  • let the indoor air become fresh. When welcoming guests to visit, or mind the smell in the room, the fragrance of the Scent Diffuser to make the air fresh.
  • Concentration. When sitting for a long time or studying alone, let the faint aroma of the Essential Oil Diffuser refreshing.
  • Relax before going to bed. When you are busy with your day and want to relax your body and mind, you will feel relaxed and comfortable through the fragrance of the aroma diffuser.
