Improving EL efficiency in blue seems to be critical to enhance the quality of display products by lowering power consumption. In order to increase exction usage in blue organic light-emitting diodes (OLEDs), phosphorescent and TADF based OLEDs have emerged from the surface, however insffucient to meet the device lifetime of blue fluorescent OLEDs. This is largely owing to the degradation of materials in emitting layer upon device operation, which motivated our research to increase device lifetime. Here, we will demonstrate our current research status on blue phosphorescent and TADF OLEDs along with our plan to utilize the technologies in the display products.
