According to reports, NECLighting, a subsidiary of NEC's lighting business, has developed an OLED panel for lighting that is twice as bright as current products under the same power consumption. According to reports, the current luminous efficiency limit of OLED panels for lighting is 60 lm / w, the current mainstream LED lighting luminous efficiency is 60-100 lm / w, and the luminous efficiency of OLED panels developed by NEC can reach 156 lm / w.
According to the report, the product developed by NEC is a 4 square panel with a side length of only 2 mm. It is planned to expand the product size to 10 cm (edge ​​length) necessary for mass production within 3-4 years, and the luminous efficiency should exceed that of LED lighting. According to the report, OLED lighting has the characteristics of allowing the entire ceiling/wall to be illuminated or curved, and is considered to be the next generation of lighting products, but the biggest problem is the high manufacturing cost and poor luminous efficiency.
