Abstract

The embodiments of the invention disclose an organic light-emitting display panel and a preparation method thereof. The preparation method of the organic light-emitting display panel comprises the following steps of: providing a substrate; preparing multiple independently-set first sub electrodes on one side of the substrate, wherein an interstitial site is formed between the adjacent two first sub electrodes, the interstitial site is filled with an insulation layer, each interstitial site comprises a first interstitial site and a second interstitial site, and the clearance between the adjacent two second interstitial sites comprises at least one first interstitial site; preparing pixel definition layers on the second interstitial site position, wherein an organic light-emitting display area is formed between two adjacent pixel definition layers; preparing the same type of organic light-emitting layers on the organic light-emitting display area; and preparing second electrodes on one sides, far from the substrate, of the organic light-emitting display layers and the pixel definition layers. In conclusion, the pixel resolution of the organic light-emitting display panel can be improved without changing the preparation process of the organic light-emitting layer in the existing organic light-emitting display panel.

Description

technical field [0001] Embodiments of the present invention relate to the field of semiconductor display technologies, and in particular to an organic light emitting display panel and a manufacturing method thereof. Background technique [0002] Organic Light-Emitting Diode (OLED) display device has self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, wide operating temperature range, and can realize flexible display With many advantages of large-area full-color display lights, it is recognized as the display device with the most development potential in the industry. [0003] At this stage, OLED display devices based on the vacuum process have been mass-produced. However, the equipment investment and maintenance costs of this technology are high, material waste is serious, it is difficult to achieve a larger area, and the cost remains high. Inkjet printing technology to prepare OLED ...
