Problems solved by technology
[0003] At present, thin-film encapsulation technology is generally used to block water and oxygen during the production of organic light-emitting display panels, but water and oxygen may still penetrate from the gap between the encapsulation layer and the light-emitting layer and the array substrate, corroding the light-emitting materials and the array substrate. Cathode materials, reducing the efficiency and lifetime of OLED devices

Embodiment Construction
[0053] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0054] In OLED devices, the light-emitting materials in the organic light-emitting structure array are usually polymers or small organic molecules, and the cathode materials are usually active metals with low work functions such as magnesium-aluminum, etc. These light-emitting materials and cathode materials are very sensitive to water vapor and oxygen. The penetration of water / oxygen will greatly reduce the lifespan of OLED devices. In order to meet the requirements of commercialization for the lifespan and stabil...

The invention discloses an organic light-emitting display panel, a preparation method and a display device, wherein the organic light-emitting display panel comprises: a first substrate; an organic light-emitting structure array layer located on the first substrate, and the organic light-emitting structure array layer includes a cathode; at least Including a first conductive line and a second conductive line, the orthographic projection of the first conductive line on the first substrate surrounds the orthographic projection of the cathode on the first substrate, and the orthographic projection of the second conductive line on the first substrate surrounds the first conductive line Orthographic projection of the wire on the first substrate; the first conductive wire is the positive pole of the original battery, and the second conductive wire is the negative pole of the original battery; or the second conductive wire is the positive pole of the original battery, and the first conductive wire is the negative pole of the original battery. The principle of the primary battery, in the primary battery composed of the first conductive wire and the second conductive wire, the negative electrode of the primary battery can be used as a sacrificial wire to preferentially consume water and oxygen, so as to prevent the water and oxygen infiltrated from the display panel from corroding the organic light-emitting structure, ensuring the organic light-emitting display panel luminous efficiency and lifetime.
Description
technical field [0001] Embodiments of the present invention relate to display technology, and in particular to an organic light emitting display panel, a manufacturing method and a display device. Background technique [0002] Organic Light Emitting Display (OLED) has self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, wide viewing angle, wide operating temperature range, and can realize flexible display and large area With many advantages such as full-color display, it is recognized by the industry as a display device with the most potential for development. [0003] At present, thin-film encapsulation technology is generally used to block water and oxygen during the production of organic light-emitting display panels, but water and oxygen may still penetrate from the gap between the encapsulation layer and the light-emitting layer and the array substrate, corroding the light-emitting materials and the array s...
