Abstract
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.
Claims18
A field emission organic light emitting diode (FEOLED) display, comprising:
- a transparent glass substrate;
- an anode electrode made of indium tin oxides (ITO) coated on the glass substrate;
- an organic electroluminescence (EL) light emitting layer formed on the anode electrode;
- a grid electrode;
- and
- a cathode electrode, from which electrons are emitted toward the anode electrode,
- wherein the organic EL light emitting layer is disposed between the anode electrode and the grid electrode;
- the grid electrode is disposed between the organic EL light emitting layer and the cathode electrode;
- and light emission is caused as electrons emitted from the cathode electrode strike the organic EL light emitting layer.
