Abstract: A manufacturing method of flexible substrates via a screen printing machine includes moving the back-ink blade and the scraper, the scraper is above the back-ink blade, and the back-ink blade is configured to coat the adhesive material on the opening; moving the back-ink blade and the scraper along an opposite direction, the scraper is lowered down to a position below the back-ink blade, the scraper prints the adhesive material from the opening to the substrate so as to form a flexible substrate thin-film corresponding to the opening area on the substrate; and applying a baking process on the flexible substrate thin-film to obtain a cured flexible substrate. The screen printing machine forms the flexible substrate thin-film corresponding to the opening of the screen printing machine to so as to obtain the flexible substrate having a predetermined dimension, which simplifies the manufacturing process and saves the manufacturing cost.

Abstract: The present invention provides an OLED display panel and a manufacture method thereof. In the manufacture method of the OLED display panel according to the present invention, the cathode of the made OLED display panel has a double layer structure. The cathode comprises a first metal layer of the entire surface and a second metal layer being located on the first metal layer and corresponding to the non pixel areas of the OLED display panel. Thus, in the pixel area of the OLED display panel, the cathode is constructed by the first metal layer and appears to be semi transparent. In the non pixel area of the OLED display panel, the cathode is constructed by stacking up the first metal layer, the second metal layer and appears to be opaque.
