Description

technical field [0001] The present invention relates to a light-emitting element, and in particular to an organic electroluminescent (OEL) element. Background technique [0002] Organic electroluminescence has the characteristics of self-luminescence, wide viewing angle (up to 160 degrees), high response speed, low driving voltage, full color, etc. It is now practical and can be applied to color flat display components, such as small display panels, outdoor displays Kanban, computer and TV screens, etc. The organic electroluminescent element uses two electrodes to sandwich an organic film with luminescent properties. When a DC voltage is applied, holes will be injected from the anode (anode) and electrons will be injected from the cathode (cathode). The potential difference makes the carriers move in the film and recombine, and part of the energy released by the recombination of electron holes will excite the light-emitting molecules to form a single excimer molecule.
