The invention discloses a production method of an organic light-emitting display panel, the organic light-emitting display panel and a device. The method comprises the steps that an organic light-emitting display device is arranged on one side of a substrate, a first middle substrate is obtained, and the first middle substrate comprises a function binding area and a cutting area; the cutting area surrounds the function binding area; a packaging layer is arranged on the whole side, away from the substrate, of the first middle substrate; and the whole packaging layer is etched to form a packaging pattern so that the cutting area surrounds a packaging projection, the packaging projection is adjacent to the function binding area, and the packaging projection is an orthographic projection of the packaging pattern on the first middle substrate. A shadow area can be prevented from appearing at the edge of the packaging layer so that the problem that the reliability of the organic light-emitting display panel is reduced due to the shadow area is avoided.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a method for preparing an organic light emitting display panel, an organic light emitting display panel and a device. Background technique [0002] In an organic light-emitting display panel, organic light-emitting materials and metal electrodes are easily eroded by internal and external water and oxygen to undergo an oxidation reaction, causing pixels to shrink or not emit light. Setting the encapsulation layer can prevent external water and oxygen from entering and corroding the organic light emitting device, thereby protecting the organic light emitting device and prolonging the service life of the organic light emitting device. [0003] However, currently, in the manufacturing process of the organic light emitting display panel, the setting method of the encapsulation layer tends to cause a shadow area on the edge of the encapsulation layer, and the shadow area eas...
