OLED

Organic Light Emitting Diodes (OLEDs) are emitting flat, plan, diffused and soft light and producing eye-catching images that have the class of natural light color, making them an ideal candidate for high-quality flat panel display. OLED technology also offers new approaches to be fabricated on flexible and stretchable substrates and its thinness, flexibility and extraordinary durability during worst mechanical conditions such as bending and twisting making it suitable for wearable electronics, biomedical appliances, electronic skins, and robotics. OLED components are capable of emitting stable and transformable light which can be tuned by the device architecture. The color and color temperature of OLEDs can be adjusted along with a wide range from 1500 to 20000 K with almost no restrictions, which generate the possibility of mimicking natural light style artificial light.

OLEDs have faced various challenges since it has been made. The reduced life expectation given the extreme sensitiveness to oxygen and moisture as well as difficulties into encapsulate devices which cause an aggravation in the degradation that making the devices very sensitive and not efficient, just to mention a few. OLEDs also suffers from its Degradation and Mechanism failures like, dark spots, pro longing its lifetime at high temperatures, extremely hot temperature and the fading of its color overtime. Nevertheless, there is one common problem which is its life expectancy. OLEDs have a high tendency to moist, meaning, it will reduce the device's lifetime causing it ot grow some dark spots Oxidation in OLED devices occurs mainly due toelectrochemical reactions, moisture attack, and creates dark, nonemissive spots in device and limits the device lifetime. Corrosion is also one of the issues of OLEDs mainly happening due to the exposure of materials/electrodes to moisture.
