The history of OLED displays is relatively short. Initially, the main drawback of this technology was a short life span of OLED cells (especially for blue color) which significantly narrowed scope of applications. Conducted research eliminated this obstacle. Currently, contrary to popular beliefs and myths, OLED technology is so refined that it can be successfully used in industrial applications. At present, OLED displays surpass LCD modules in all respect and their liveliness varies from 50 000 to 110 000 hours (depending on the color).
