Abstract

The invention provides a flexible OLED and a manufacturing method thereof. The flexible OLED covers an auxiliary conductive layer (13) via a second electrode (12), resistance of the second electrode (12) can be reduced, conductivity is improved, various pixels are uniform in voltage, and uniformity in display is improved. The second electrode (12) can be thinned, and materials of the second electrode (12) are saved. The manufacturing method of the flexible OLED includes forming the auxiliary conductive layer (13) of the second electrode (12) on the second electrode (12), resistance of the second electrode (12) can be reduced, conductivity is improved, the pixels are uniform in voltage, display uniformity is improved, the second electrode (12) can be thinned, and materials of the second electrode (12) are saved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible OLED and a manufacturing method thereof. Background technique [0002] Organic light emitting diode display device (Organic Light Emitting Diode, OLED), with self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, wide operating temperature range, can realize Flexible display and large-area full-color display have many advantages, so they have received widespread attention, and as a new generation of display methods, they have gradually replaced traditional liquid crystal displays and are widely used in mobile phone screens, computer monitors, and full-color TVs. OLEDs, unlike traditional liquid crystal displays, do not require a backlight and use very thin coatings of organic materials and glass substrates that emit light when an electric current passes through them. [0003] see...
