The essential thought of this patent is that organic emission layer is
utilized instead of inorganic phosphor thin film in field emission
display (FED). The field emission organic light emitting diode (FEOLED)
in this invention is configured with an electron multiplier (dynode)
between the cathode of FED and the organic emission layer, wherein
secondary electron material is coated in the holes of the dynode. The
design for the organic emission layer, which includes a hole injection
layer (HIL), a hole transport layer (HTL) and an emission layer (EL), is
able to attain higher luminance and lower power consumption for the
innovative FEOLED than conventional OLED.
