OLED lighting is a new type of solid-state lighting technology, the biggest feature is its non-glare (Non-Glaring) characteristics, can long-term lighting in the dark, without causing eye fatigue. Although there will not be a large-scale growth rate in a short period of time, it is expected that the OLED lighting market will be expected to grow to 2.5 billion U.S. dollars in 2027, which is expected to open up a new situation for the global lighting market.
According to Khasha Ghaffarzadeh, head of consulting at IDTechEx, the lighting market has a very wide range of structures and is full of different technology combinations and different customer needs. Including homes, office space, industrial plants, shops, outdoor environments, etc. all have varying degrees of energy efficiency, life, light intensity, color temperature, and design requirements.
If divided by the field, it will be seen that the indoor application areas such as hotels and shops will be first introduced into OLED lighting. In view of the news that BMW will introduce OLED lighting into the lights in 2015, the introduction of automotive lighting is also very optimistic. However, life and reliability still need to be improved. Once the cost is reduced and the service life is extended, OLEDs can be gradually introduced into homes, offices, and outdoor areas.
The thin, flexible nature of OLED lighting makes its application design more flexible and allows the use of less materials. In addition, OLED lighting does not emit heat and does not contain ultraviolet light, making it ideal for outdoor lighting. Artificial sources of ultraviolet light may cause damage to human skin, and may also attract insects. However, OLED light sources do not have ultraviolet rays, and thus can be used outdoors to prevent people from being harassed by mosquitoes.
IDTechEx predicts that the OLED lighting market will grow to $2.5 billion by 2027. However, by 2020, growth will be very slow. In particular, LED lighting has been successfully introduced into the market. The technology, cost structure, and supply chain have all been significantly improved, and the huge cost gap between LEDs and OLEDs has been widened. Although OLED lighting leaders such as Konica Minolta and LG have all gained important technical gains in recent years, the performance gap has not been reduced too much.
Therefore, the first challenge facing OLED lighting is to make market differentiation. Many companies such as Osram and Philips have achieved success in LED lighting, and their business volume has not grown. Investing in OLEDs can provide hedging bets, as well as a means to emerge from the increasingly commercial LED market.
