OLED stands for organic light-emitting diode, a display device that sandwiches carbon-based films between two charged electrodes, one a metallic cathode and one a transparent anode, usually being glass. The organic films consist of a hole-injection layer, a hole-transport layer, an emissive layer and an electron-transport layer. When voltage is applied to the OLED cell, the injected positive and negative charges recombine in the emissive layer and create electro-luminescent light.
OLED displays are emissive devices - they emit light rather than modulate transmitted or reflected light. OLED is widely used in handheld devices such as PDAs and mobile phones, car audio systems and digital cameras. OLEDs are bright, thin, lightweight and deliver fast response times while using low power and offering high contrast ratio. OLED displays do not require a backlight.

Established in 1949, NEG is currently a top tier TFT-LCD glass manufacturing company. NEG supplies glass substrates that companies use at their fifth and sixth generation TFT-LCD fabrication plants worldwide.
The glass substrates that are manufactured during the front-end process are cut and rinsed during the back-end process, and are then ready to be used as mother glass substrates at LCD production lines.
