LEDs and OLEDs are the two key technologies for advanced lighting and display solutions.
Main devices are:
- LEDs (light-emitting diodes) are semiconductors with the advantages of being relatively cheap, durable, and as the light is directional it can be used more efficiently than conventional lighting. A major drawback is that LED panels are rigid and cannot be shaped into unique designs.
- OLEDs (organic light-emitting diode) comprise thin layers of organic compounds that emit light through electric currents. Their main advantages over LEDs are better colour fidelity, efficiency, and operation stability, and as OLED panels are flexible, they offer enhanced design opportunities. These features are making OLEDs the technology of choice for high-end television systems, computer monitors, and displays for mobile phones, wearables, digital cameras, and portable gaming consoles.
