Optimize Yields While Enhancing Large-Format Display Performance

DuPont Addresses Needs of OLED (AMOLED) Display Market

By closely tailoring the materials and process to work together, DuPont has optimized color saturation, current efficiency, voltage and lifetime to address the needs of the active matrix OLED (AMOLED) display market.

Specifically, DuPont is able to tune ink formulations and process conditions to optimize intra-pixel and long-range uniformity. In addition, DuPont has developed techniques to characterize the uniformity from subpixel to subpixel to significantly minimize luminance stitching, a common challenge for printing technologies.

Using the DuPont liquid printing process and suite of innovative, high-performance, solution-based materials, display manufacturers may achieve:

• in-pixel thickness aperture of >95%
• a thickness variation of ~2 nm across the plate
• with long-range uniformity >90%.

Short-Range Uniformity of Printed Displays Using the DuPont OLED Liquid Printing Process Exceeds the Performance of Commercial LCDs (U_sh = 0.93).
 

Printed Lifetime - Even for Blue, the Most Challenging color - Exceeds 30,000 Hours and Should Be Sufficient for OLED TVs.
