Blue OLED phosphorescent materials have poor color accuracy, and related terminal display products are expected to be shipped as early as 2026

According to a report by Korean media The Elec, OLED material giant UDC’s blue OLED phosphorescent material faces the problem of poor color accuracy, which may affect the further delay of the launch of terminal display products.

According to previous reports on this site, in addition to UDC, Samsung Display itself is also developing blue OLED phosphorescent materials.

In OLED panels, phosphorescent materials can theoretically achieve nearly 100% exciton energy conversion rate, while fluorescent materials can only achieve 25%. The use of phosphorescent materials can greatly improve OLED energy efficiency, thereby reducing power consumption, extending battery life, and increasing brightness.

Current OLED products have already adopted the other two primary colors - red and green. Phosphorescent glow. Butin the blue part, phosphorescent materials have lifespan and color accuracy issues, so fluorescent materials continue to be used for now.

UDC has been advocating for the commercialization of blue OLED phosphorescent materials this year.

However, industry insiders revealed that UDC’s materials have unstable performance problems. Specifically, this material will emit light containing green, producing a visual effect close to cyan.

UDC is taking into account the development cycle of the product, as well as the AVPasiόn message. They plan to complete the plan before the end of this year and use pure phosphorescent OLED (PHOLED) end products, which will not be mass-produced until 2026.

It is expected that mobile phones and tablets will be the first devices to apply PHOLED.

In order to improve the brightness of OLED, LG Display uses more precise deuterated materials, which greatly improves the brightness of blue OLED fluorescent materials. In this way, not only the maximum brightness is improved, but also the service life is extended. This technology has been widely used in large-scale OLED panel manufacturing.
