Problems solved by technology

On the other hand, in the reflective layer of the display panel, the reflectivity is often the same everywhere, which will cause differences in the melting speed of the packaging material under different laser energies, thus adversely affecting the packaging effect

Abstract

The embodiment of the invention discloses a display panel, a display device and a manufacturing method. The display panel comprises a display area, packaging areas surrounding the display area, a substrate and a cover board arranged oppositely to the substrate, wherein a packaging layer is arranged on the surface, toward the substrate, of the cover board in each packaging area; the packaging layers are used for being bonded to the substrate and the cover board after being irradiated by laser light; a plurality of reflecting blocks are formed on the surface, toward the cover board, of the substrate in each packaging area; and the reflectivity of various reflecting blocks is reduced along with an increase of the intensity of the laser light at the positions of various reflecting blocks. According to the display panel, the melting rates of the packaging layers under different intensity of the laser light can tend to be consistent, thereby reducing the defects, such as cracks, caused by astress difference, of the packaging areas. Meanwhile, improvement of the packaging bonding strength between the substrate and the cover board is facilitated, thereby improving the manufacturing yieldof the display panel.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a display device and a manufacturing method. Background technique [0002] At present, the packaging principle of the existing display panel is as follows: firstly, a reflective layer is formed on the substrate, and an encapsulation layer is formed on the cover plate; then the cover plate is irradiated with laser light. At this time, the reflective layer can reflect the incident laser light, and the encapsulation material in the encapsulation layer is melted under the action of the laser light and the reflected laser light, so as to realize the encapsulation and bonding of the substrate and the cover plate. [0003] However, the energy distribution of the laser can be regarded as a Gaussian distribution, that is, the energy of the laser at the middle of the energy distribution area is high, and the energy of the laser at both sides of the energy distri...
