Problems solved by technology
When the adhesive is heated and melted by lasers such as infrared rays, the adhesive will not only adhere to the surface of the reflective layer, but also usually adhere to the inorganic material layer or the fan-out wire exposed by the bonding hole, thereby The stress mismatch between the inside and outside of the bonding hole will cause the adhesive to have defects such as cracks after melting, and the water and / or oxygen barrier performance of the organic light-emitting display panel is poor, which reduces the production quality of the organic light-emitting display panel.

The present application discloses an organic light-emitting display panel, a preparation method, and an organic light-emitting display device. The organic light-emitting display panel includes: an array substrate including a display area and a non-display area surrounding the display area; a reflective layer arranged on the non-display area of the array substrate. The display area and surrounding the display area, the reflective layer is provided with a plurality of bonding holes; the stress relief structure is arranged in each bonding hole; the cover plate is arranged opposite to the array substrate; the adhesive is located between the array substrate and the cover plate space between the array substrate and the cover plate, the adhesive is filled in the gap between the stress relief structure and the bonding hole, and the stress relief structure is used to release the stress generated when the adhesive is bonded to the bonding hole; the array substrate It also includes a plurality of fan-out leads electrically connected to the driver chip. The above stress release structure can release the stress in the bonding hole where it is located, avoid cracks in the adhesive, and improve the production yield of the organic light emitting display panel.
Description
technical field [0001] The present application generally relates to the field of display technology, in particular to the field of organic light-emitting display technology, and specifically relates to an organic light-emitting display panel, a manufacturing method, and an organic light-emitting display device including the organic light-emitting display panel. Background technique [0002] OLED, that is, Organic Light-Emitting Diode (Organic Light-Emitting Diode), also known as organic electroluminescent device, its light-emitting principle is mainly: organic semiconductor materials and light-emitting materials are driven by an electric field through carrier injection and recombination. glow. Organic electroluminescent devices have many advantages such as self-luminescence, high efficiency, low voltage, fast response, wide viewing angle, and can be made on flexible substrates. They can be made into displays or lighting devices, and have attracted much attention from the soc...
