[forty two] A lot of modern-day OLEDs integrate a simple bilayer structure, consisting of the conductive layer and an emissive layer. Developments in OLED architecture in 2011 improved quantum efficiency (up to 19%) by making use of a graded heterojunction.[forty three] While in the graded heterojunction architecture, the composition of hole and electron-transportation elements differs constantly throughout the emissive layer which has a dopant emitter. The graded heterojunction architecture combines the main advantages of equally typical architectures by bettering demand injection when simultaneously balancing demand transport throughout the emissive region.[forty four]
