Moreover, the OLED display screen can be made lighter and thinner, with a larger viewing angle, and can significantly save power consumption.

OLED  also named the third-generation display technology. OLED is not only lighter and thinner, low energy consumption, high brightness, good luminous efficiency, can display pure black, but also can be curved, such as today’s curved screen TVs and mobile phones. Nowadays,Lots manufacturers are scrambling to increase their R&D investment in OLED technology, making OLED technology more and more widely used in TV, computer (display), mobile phone, tablet and other fields.
