Abstract

The invention discloses an organic light-emitting display panel, a manufacturing method thereof and a display device. The manufacturing method of the invention adopts a laser drilling process after forming a first encapsulation structure on the cathode so that the cathode passes through the via hole penetrating the organic functional layer and contacts The control electrode traces are electrically connected, and then the second packaging structure covering the first packaging structure is formed, so that the first packaging structure formed earlier can avoid the generation of dust in the drilling process and affect the performance of the device, that is, the present invention uses the existing In the process of packaging technology, laser drilling is performed to make the cathode conductive. Therefore, the method for manufacturing the organic light-emitting display panel provided by the embodiment of this aspect can avoid the laser drilling process on the basis of ensuring the stability of device packaging in the prior art. The impact of the generated dust on the device, thereby improving the performance of the device.

Description

technical field [0001] The present invention relates to the technical field of organic electroluminescence, in particular to an organic light-emitting display panel, a manufacturing method thereof and a display device. Background technique [0002] Compared with liquid crystal display devices, Organic Light Emitting Diode (OLED) has advantages such as self-illumination, fast response, wide viewing angle, high brightness, bright colors, light and thin, etc., and is considered to be a next-generation display technology. The self-luminous element, that is, the OLED device, is mainly composed of an anode, a light-emitting functional layer and a cathode arranged away from the substrate. [0003] At present, due to the thinness of the touch screen with the embedded self-capacitive touch structure, most of the existing OLED-based touch products adopt the embedded self-capacitive touch structure. In the structural arrangement of the control method, the cathode is located at the top...
