The application of blue phosphorescent material can reduce the power consumption of OLED display panels by 25%, Universal Display Corp Vice President of Business Development Mike Hack told TheElec in an interview.
UDC’s plan to start producing blue phosphorescent material in 2024, which it previously announced, was also on track, Hack said in an interview on the sidelines of the K-Display conference held last week in Seoul.
This first-generation blue phosphorescent material will reduce the total power consumption of OLED displays by 24% to 25%, he said.
In currently commercialized OLED display panels, phosphorescent materials are used for red and green but when it comes to blue they are made using fluorescent material.
Replacing the blue fluorescent with blue phosphorescent material will also maintain the cost competitiveness of panels as the overall costs of these materials are minimal, Hack said.
Individual customers of UDC had their own respective plans on which applications they want to use the blue phosphorescent material and the company was not in the position to divulge that information, the VP also said.
In terms of profitability from blue phosphorescent material, UDC was taking a long-term view and it expected OLED application in AR and VR as well as IT devices to expand quickly, Hack said.
For the next ten years, demand and market for OLED will grow quickly, with the technology becoming dominant in the display sector, the VP said.
On Apple’s Vision Pro device unveiled in June, the VP said MicroOLED technology applied on the device is in its early stages but more companies will apply MicroOLED on their headset products.
Blue phosphorescent material can also be applied on the white OLED and color filter format of OLED display panels and will depend on how the panel makers want to organize its stack, or emission layers, for their panels, Hack also said.
On MicroLED technology, Hack said while it was an interesting technology it won’t be able to secure the competitiveness of OLED. MicroLED faced issues with performance, efficiency, and die size as well as yield, he added.
