If the technology is successful in pilot line, it is possible that the QD-OLED process lines planned for future may be converted to the QNED architecture where the blue OLED will be replaced by the Nanorod LED. Samsung Display has improved upon its QNED (quantum dot nanorod LED) display technology to a near production level. The company is expected to start investing in production equipment by 2021, and a GaN-based nanorod LED array with dislocation-free and large sidewall-surface-area characteristics was demonstrated.5 The nanorod LED array showed an enhanced internal quantum efﬁciency and light extraction efﬁciency. However, the major challenge of making electrical contacts to nanorod LEDs having a typical diameter of 10–100 nan- That replacement is Gallium Nitride (GaN) which comes in the form of a blue emitting Nanorod LED. The increased stability of GaN should also remove the necessity for thin film encapsulation which is a finishing stage that OLED panels have to go through to make sure they are not exposed to oxygen or moisture which reduces the lifespan of the panel.
