In addition to LEDs, the biggest dark horse in the future of lighting will be non-OLED. OLED and LED are both solid-state lighting technologies, and their luminous efficiency greatly exceeds the widely used fluorescent lamps. Their advantages such as no mercury, no ultraviolet light, high color rendering and adjustable light intensity can meet the needs of next-generation lighting applications. Therefore, OLED has entered the lighting industry with a strong black horse. However, the biggest problem with OLEDs is still that the cost price is too expensive, which makes OLEDs become the emerging lighting technology that is currently not so popular.
Â
   According to the latest research report by research institute DisplaySearch, the OLED lighting market is expected to take off in 2011. The overall OLED lighting market output value is expected to surpass the passive matrix OLED display market between 2013 and 2014. The market size is expected to be 2018. Reached $6 billion.
   Although OLEDs and LEDs have similar names, they are technically quite different. OLED has several irreplaceable lighting advantages. For example, OLED is a diffused light source, so it emits soft light and has a light and thin appearance. In addition, the use of a flexible substrate can be changed to a different shape. If a transparent electrode is used, the transmittance is like glass when the lamp is not turned on. These features make the range of OLED lighting applications more extensive than the prior art.
   As for the commercialization schedule of OLED lighting, OLEDs are still low in luminous efficiency and high in cost, so no commercial products have emerged. It is expected that by 2015, OLED luminous efficiency will catch up with fluorescent tubes, but due to high prices, OLEDs for lighting are expected to account for only 4% of the lighting market. Until 2020, OLED lighting brightness, luminous efficiency, price, etc. will be close to LED, the lighting market can be widely accepted, then the market size will reach 8 billion US dollars, accounting for about 10% of the overall lighting market.
   At present, countries including Europe, the United States and Japan have invested a large amount of money to develop OLED lighting technology. Although OLED displays have been introduced into mass production for decades, OLED lighting still has only a small number of samples shipped, because both OLED displays and OLED lighting face different application problems. . It is expected that by 2018, the OLED lighting market will have six main applications, including automotive lighting, display backlighting, decorative/general lighting, healthcare and industry, and the city's regular DisplaySearch. It is estimated that by 2011, many manufacturers OLED lighting products will be officially produced, including Philips, Osram, General Electric, Konica Minolta and Lumiotec.
   The lighting industry is a huge market. Following the current LED, OLED is believed to be the next star of the next lighting industry. However, the high cost of shackles of new technologies and the illuminating efficiency still lag behind LEDs, so OLEDs still have to work hard before the technology shines. However, its technical advantages are indeed expected in the future lighting market.
