This work presents novel field emission organic light emitting diodes (FEOLEDs) with dynode
in which an organic EL light-emitting layer is used instead of an inorganic phosphor thin film in the field emission display (FED). The proposed FEOLEDs introduce field emission electrons into organic light emitting diodes (OLEDs)
which exhibit a higher luminous efficiency than conventional OLED. The field emission electrons emitted from the carbon nanotubes (CNTs) cathode and to be amplified by impact the dynode in vacuum. These field emission electrons are injected into the multi-layer organic materials of OLED to increase the electron density. Additionally
the proposed FEOLED increase the luminance of OLED from 10 820 cd/m
2
to 24 782 cd/m
2
by raising the current density of OLED from an external electron source. The role of FEOLED is to add the quantity of electrons-holes pairs in OLED
which increase the exciton and further increase the luminous efficiency of OLED. Under the same operating current density
the FEOLED exhibits a higher luminous efficiency than that of OLED.
