Abstract

The invention discloses a foldable flexible transparent anode. The foldable flexible transparent anode comprises an ITO film and a nano silver wire transparent conductive film, wherein the ITO film and the nano silver wire transparent conductive film are coated between an OLED (organic light emitting diode) and a flexible substrate; the pattern of the ITO film is coincided with the pattern of a nano silver wire transparent conductive film; the ITO film is positioned on one side of the OLED; the nano silver wire transparent conductive film is positioned on one side of the flexible substrate; and the thickness of the ITO film is 10 to 20 nm. The transparent anode disclosed by the invention has the work function of the ITO film and the extensibility and conductivity of the nano silver wire film, is particularly suitable for being applied to foldable flexible OLED display panels and OLED illumination, and the conductivity of the anode cannot be influenced even though the ITO is broken dueto repeated bending of the OLED.

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...
