OLED (Organic Light Emitting Diode) is the Emitting Light emitted by Organic semiconductor materials and Emitting materials that are driven by an electric field through carrier injection and composite.OLED light-emitting diodes (OLED) are classified as light emitting diodes (OLED) and polymer light emitting diodes (PLED), depending on the emitting layer material.
Overall, OLED lighting has the advantage of high luminous efficiency, is suitable for a large area of surface light source, fast switching speed, and for users in different regions, can adjust its color to meet various color temperature requirements.Secondly, OLED lighting can achieve soft material, easy to cut, light and thin shape, and low driving voltage and other characteristics, quite in line with the current popular green environmental protection requirements.
In the field of solid state lighting, newer generation lighting technology OLED has been developed rapidly.As a planar light source, OLED has incomparable advantages over traditional LED lighting in terms of structure, light quality and product characteristics.OLED lighting is expensive, but can be balanced by improved life and efficiency over time.Moreover, due to its thin plane and soft characteristics, it can be considered to develop into the high-end consumer field and the construction market, and complement with LED lighting in use, so as to become the future green lighting source.
Global sales of OLED lighting will reach $2.4 billion by 2020 and $5.5 billion by 2025.In the context of limited global energy resources and growing demand for sustainable energy for environmental protection and development, solid-state lighting will trigger an epochal lighting revolution and is expected to become a new generation of light source after incandescent lamps and fluorescent lamps.
At present, OLED lighting technology is comparable to mature LED lighting in terms of research and development. With the deepening of research, the efficiency, service life and brightness of OLED lighting will be further improved and will enter the lighting market more quickly.To sum up, European and American manufacturers have huge advantages in OLED lighting patents and ideas, etc. Other Asian countries, such as China, must break through the thick patent wall and rapidly improve their innovation ability in all aspects if they want to break through.
