According to ‘AMOLED Manufacturing Process Report Ver.5’ recently published by UBI Research, QM2, a new emitting structure of QD-OLED, has been applied from the end of 2022, and is expected to be applied to Samsung Electronics’ 2023 OLED TVs.
QD-OLED, which is being mass-produced by Samsung Display, consists of three blue emitting layers and one green emitting layer, and is a structure in which the three primary colors of RGB are expressed through quantum dots and color filters.
In the QM1 structure mass-produced by the end of 2022, there was no aETL and G’ in the green emitting layer, but it was confirmed that all of them were applied from the QM2 structure. In addition, the change cycle of the emitting structure is expected to be extended from one year to two years due to recycling of materials.
Meanwhile, Samsung Display is expected to expand its existing 30K monthly QD-OLED Capa. to 45K monthly by 2024. In addition, from 2023, it plans to further expand its lineup by mass-producing 49-inch and 77-inch panels in addition to 55-inch and 65-inch panels.
