What is Organic EL (Electro Luminescence)?

Organic EL is the phenomenon of light emitted by organic materials to which a voltage has been applied. OLED (Organic Light Emitting Diode) are devices that employ this phenomenon. カジノ シークレット 入金 不要 ボーナスmitting color varies depending on the molecular structure of the organic materials. OLEDs are expected to be used as next-generation displays and lighting. Because it is available in a range of colors, shapes and sizes, it provides a greater degree of flexibility in the design for various space and application.

Light emission principle

When a voltage is applied to OLED, the holes (positive electric charge) and カジノ シークレット 入金 不要 ボーナスlectrons (negative electric charge) are injected from each of the two electrodes.
When they recombine in カジノ シークレット 入金 不要 ボーナスmissive layer, organic materials turn into a high energy state termed "excited state".
カジノ シークレット 入金 不要 ボーナスxcess energy is released as light when the layer returns to its stable state, termed "ground state" .

Polymer OLEDs' Advantages

over LCDs	over small-molecule OLEDs (Vapor deposition method)
Higher picture quality (Superior contrast, high response speeds, and wide viewing angle, etc.) Lower energy consumption Self-luminescent (no backlights required) and simpler display structure.	Applicable to larger display fabrication. Greater potential to realize much more cost-effective production.
