Title:
TRANSPARENT OLED DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/227754
Kind Code:
A1
Abstract:
A transparent organic light-emitting diode (OLED) display panel and a manufacturing method therefor. The transparent OLED display panel comprises: a transparent substrate (1) and a plurality of sub-pixels (20) that are arranged in an array on the substrate. Each sub-pixel (20) comprises: an anode (21) that is disposed on the substrate (1), an organic light-emitting layer (22) that is disposed on the anode (21), and a transparent cathode (23) that is disposed on the organic light-emitting layer (22). The anode (21) comprises: a first transparent electrode (211), a reflective electrode (212) that is stacked on the first transparent electrode (211), and a second transparent electrode (213) that is stacked on the reflective electrode (212); a hollow region (214) is formed at the center of the reflective electrode (212), and by means of forming the hollow region (214) on the reflective electrode (212) of the anode (21), light may be simultaneously emitted from the cathode (23) and the hollow region (214), thereby achieving transparent display, while having a simple and stable structure, a high yield, and low production costs.
