Growth and Challenges in OLED Manufacturing
Supply-and-demand issues must be addressed before OLEDs are widely used in large displays.
by Rengarajan Srinivasan, Frost & Sullivan
Organic light-emitting diodes (OLEDs) are quickly becoming the next generation of small displays. Although the technology is still emerging, it has been used already in personal media displays such as MP3 players and mobile phone subdisplays. The advantages offered by OLEDs — slimmer and thinner displays and the lack of backlight — are driving their adoption.
Further commercialization of OLEDs is dependent upon the success of current research. The major challenges faced by the industry are in large-scale manufacturing, and in material lifetime and efficiency. The use of vacuum deposition techniques for small-molecule OLEDs is not feasible in the large-scale manufacturing of bigger displays. At present, 2-in. panels are the most common size in use; however, market participants are focusing on displays of larger than 15 in.
