Abstract

The invention discloses a foldable and flexible transparent anode, which comprises an ITO film and a nano silver wire transparent conductive film coated between an OLED and a flexible substrate. The pattern of the ITO film overlaps with the wire pattern of the nano silver wire transparent conductive film. The ITO film is located on the side of the OLED, and the transparent conductive film of the nano-silver wire is located on the side of the flexible substrate. The thickness of the ITO film is 10-20 nm. The transparent anode of the present invention has both the work function of the ITO film and the nano-silver wire. The ductility and conductivity of the film are especially suitable for use in foldable flexible OLED display panels and OLED lighting. Even if the OLED is broken after repeated bending, it will not affect the conductivity of the anode.

Description

technical field [0001] The invention belongs to the field of OLED display panels, and more particularly relates to a foldable and flexible transparent anode and a manufacturing method thereof. Background technique [0002] Portable electronic products are required to be light, thin and short in design, but they also want a large display area. The emergence of foldable flexible display panels just meets this need. [0003] Regardless of whether it is a flexible or rigid OLED, the transparent electrode of the display panel is an indispensable part. At present, the traditional method of making the transparent electrode of the display panel is to coat the substrate with an ITO film and then use a yellow photoetching process to form a wire pattern. Due to the lack of ductility of the traditional ITO transparent conductive film (easy to break when folded) and the high impedance, it is not suitable for foldable and medium-to-large displays. Moreover, due to the limited reserves o...
