Palo Alto, Calif. -- April 19, 2004 -- Following exceptional end-user interest in organic light emitting diodes (OLEDs), manufacturers have been under pressure to improve specific product features such as material lifetime, device stability, and light extraction. Rigorous research and development activities are being conducted to enhance these aspects and help increase uptake of OLED products.
To establish a clear lead over competing technologies such as liquid crystal display (LCD), manufacturers have to ensure that the superior brightness, luminance, and color performance of OLED devices do not deteriorate with age or use. Concerted efforts are also underway to find a low cost solution to reduce the impact of hostile environments such as heat, moisture, and dust while preserving the advantages of low weight and thin profile.
"Initiatives to enhance device stability are important because improved blue, green, and red emitters with longer lifetimes are necessary to scale up efficiency," states Frost & Sullivan Research Analyst Hrishikesh Bidwe.
Considerable research is being conducted on developing an easily manufacturable structure that forwards more light emitted from organic molecules without increasing the reflection of ambient light. Several companies are also collaborating to develop innovative OLEDs to meet consumer demand.
The hectic pace of technology development in the OLED market has led to prominent manufacturers ramping up production to introduce greater volumes of OLED-based products commercially.
Currently, small molecule OLEDs (SMOLEDs) are proving to be the biggest challenger to LCD, especially in the small-sized displays market. Constraints in current manufacturing techniques make SMOLEDs unsuitable for large displays, leading them to target the sub-display segment in mobile phones. Innovative marketing has resulted in SMOLEDS being used in 90 percent of flip phones with sub-displays.
"SMOLEDs, by being slimmer and more lightweight and power efficient, are stealing the march over LCD technology in cell phones and camera markets as well," remarks Bidwe. "Their advantage is pressed on by the fact that while SMOLEDs can be as thin as its circuitry, LCDs' requirement for backlighting adds to the thickness and heaviness of the device."
SMOLEDs have a host of other benefits such as wide viewing angles, full color capability, and much higher contrast ratios over LCDs. With such superior features and increasing research on newer manufacturing techniques, OLEDs are all set to extend their domination from small-sized displays to all display segments very soon.
