Fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present invention, and referring to fig. 1, the display panel provided in this embodiment includes a substrate 110, a light emitting device layer 120, a cover plate 130, a frame sealing adhesive layer 140, and a light shielding layer 150; the light emitting device layer 120 is positioned at one side of the substrate 110; the cover plate 130 is positioned on a side of the light emitting device layer 120 away from the substrate 110; the frame sealing adhesive layer 140 is located between the cover plate 130 and the substrate 110, and the frame sealing adhesive layer 140 is used for connecting the cover plate 130 and the substrate 110; the light-shielding layer 150 is located on a side of the light-emitting device layer 120 away from the substrate 110, and a vertical projection of the light-shielding layer 150 on the substrate 110 is located between a vertical projection of the light-emitting device layer 120 on the substrate 110 and a vertical projection of the frame sealing adhesive layer 140 on the substrate 110.
Specifically, the substrate 110 may be a low temperature polysilicon substrate. The substrate 110 includes a display region and a non-display region. The light emitting device layer 120 is positioned in the display region. The frame sealing adhesive layer 140 and the light shielding layer 150 are both located in the non-display region, and the thickness of the light shielding layer 150 may be smaller than that of the frame sealing adhesive layer 140. The light emitting device layer 120 includes a plurality of sub-pixels including a sub-pixel emitting red light, a sub-pixel emitting green light, and a sub-pixel emitting blue light. The frame sealing adhesive layer 140 may be a glass adhesive layer, and the frame sealing adhesive layer 140 is fixedly connected to the substrate 110 and the cover plate 130. The material of the cover plate 130 may include glass.
The light-shielding layer 150 has a strong light-shielding property, and the light transmittance of the light-shielding layer 150 is low. When the frame sealing adhesive layer 140 is sintered by laser, the light shielding layer 150 can block laser from irradiating the edge of the light emitting device layer 120, so that energy of part of the laser is concentrated on the light shielding layer 150, and the problem that the edge of the light emitting device layer 120 is burnt due to the concentration of the energy of part of the laser on the light emitting device layer 120, which causes abnormal display of the edge of the display area, is solved. Since the light shielding layer 150 can reduce the laser that falls into the edge of the light emitting device layer 120, it is not necessary to set the edge of the frame sealing adhesive layer 140 that is too far away from the light emitting device layer 120, and thus, the distance from the frame sealing adhesive layer 140 to the edge of the light emitting device layer 120 can be reduced after the light shielding layer 150 is set in this embodiment, and the size of the non-display area of the display panel is reduced. The minimum distance from the frame sealing adhesive layer 140 to the edge of the light emitting device layer 120 may be the width of the light shielding layer 150, that is, there is no gap between the vertical projection of the light shielding layer 150 on the substrate 110 and the vertical projection of the light emitting device layer 120 on the substrate 110, and there is no gap between the vertical projection of the frame sealing adhesive layer 140 on the substrate 110.
The vertical projection of the light shielding layer 150 on the substrate 110 is not overlapped with the vertical projection of the light emitting device layer 120 on the substrate 110, so that the light shielding layer 150 can be prevented from shielding the light emitted by the light emitting device layer 120 to influence the display effect of the display panel.
The embodiment provides a display panel, and a light shielding layer in the display panel can reduce light falling into the edge of a light-emitting device layer when a frame sealing glue layer is sintered by laser, so that the problem that the edge of the light-emitting device layer is burnt is solved. In addition, because the light shield layer can reduce the laser that falls into the border on light emitting device layer, consequently, need not to set up the too much border of keeping away from the light emitting device layer of frame sealing glue film. Therefore, the display panel provided by the embodiment can improve the problem of abnormal display at the edge of the display area of the display panel, and can also reduce the size of the non-display area of the display panel.
Optionally, with continued reference to fig. 1, the light shielding layer 150 is located on the surface of the cover plate 130 close to the light emitting device layer 120.
Specifically, the light-shielding layer 150 is disposed on the surface of the cover plate 130 close to the light-emitting device layer 120, so that the thickness of the display panel is not increased by the light-shielding layer 150. The light shielding layer 150 is located on one surface of the cover plate 130, that is, the light shielding layer 150 is in direct contact with the cover plate 130, so that the laser falling into the edge of the light emitting device layer 120 can be shielded to the maximum extent, and the problem of abnormal edge display of the display area is further improved. In addition, the light-shielding layer 150 directly contacts the cover plate 130, and when the light-shielding layer 150 is manufactured, the material of the light-shielding layer 150 can be directly deposited on the cover plate 130, so that the manufacture of the light-shielding layer 150 is facilitated, the manufacturing process of the display panel is reduced, and the manufacturing cost of the display panel is reduced.

Specifically, the light-shielding layer 150 is disposed on the surface of the cover plate 130 away from the light-emitting device layer 120, which is beneficial to disposing and removing the light-shielding layer 150, and is also beneficial to rapidly dissipating heat generated by laser irradiation from the light-shielding layer 150. Similarly, the light shielding layer 150 is disposed on the surface of the cover plate 130 far from the light emitting device layer 120, so that the light shielding layer 150 is in direct contact with the cover plate 130, thereby shielding the laser beam falling into the edge of the light emitting device layer 120 to the maximum extent and further improving the problem of abnormal edge display in the display area. In addition, the light-shielding layer 150 directly contacts the cover plate 130, and when the light-shielding layer 150 is manufactured, a material of the light-shielding layer 150 can be directly deposited on the cover plate 130, so that the manufacturing of the light-shielding layer 150 is facilitated, the manufacturing process of the display panel is reduced, and the manufacturing cost of the display panel is reduced.

Specifically, the first light-shielding sublayer 151 and the second light-shielding sublayer 152 are respectively located on two surfaces of the cover plate 130, which are opposite to each other, and when the frame sealing adhesive layer 140 is sintered by laser, the first light-shielding sublayer 151 and the second light-shielding sublayer 152 can simultaneously shield part of laser, so that the light-shielding performance of the light-shielding layer 150 is improved, the laser falling into the edge of the light-emitting device layer 120 is further reduced, and the problem of abnormal edge display in the display area can be obviously improved.
Optionally, the material of the light shielding layer includes at least one of molybdenum, gold, silver, and aluminum.
Specifically, because the light transmittance and the light reflection rate of metal materials such as molybdenum, gold, silver and aluminum are low, the light shielding layer comprising at least one of molybdenum, gold, silver and aluminum has high light reflection rate and low light reflection rate, so that a small part of laser irradiated on the light shielding layer even no laser penetrates through the light shielding layer, and most of laser penetrates through the cover plate again and is reflected out.
Alternatively, fig. 4 is a schematic structural diagram of another display panel provided in accordance with an embodiment of the present invention, and referring to fig. 4, a smaller vertical distance a from the edge of the light emitting device layer 120 to the edge of the frame sealing adhesive layer 140 is greater than or equal to a set distance; the set distance is: (c-b)/2; wherein c is the diameter of a light spot of laser on the cover plate when the frame sealing adhesive layer 140 is sintered by laser, the vertical distances from the center of the light spot to the two side edges of the frame sealing adhesive layer 140 are equal, and b is the width of the frame sealing adhesive layer 140.
Specifically, the frame sealing adhesive layer 140 surrounds the edge of the light emitting device layer 120. Referring to fig. 4, there are two vertical distances from the edge of the light emitting device layer 120 to the edge of the frame sealing adhesive layer 140, one vertical distance is a, one vertical distance is d, and a is a smaller vertical distance. When the frame sealing glue layer 140 is sintered by laser, the shape of a light spot of the laser falling on the cover plate is circular, the diameter of the circle is c, and the center of the light spot is the center of the circle. The two side edges of the frame sealing adhesive layer 140 are: when the frame sealing adhesive layer 140 is sintered by laser, two sides perpendicular to the surface of the frame sealing adhesive layer 140 are covered by the light spots. The width of the frame sealing adhesive layer 140 is a difference between a first distance e and a second distance f, the first distance e is a smaller vertical distance from the edge of the frame sealing adhesive layer 140 far away from the light emitting device layer 120 to the edge of the light emitting device layer 120, and the second distance f is a smaller vertical distance from the edge of the frame sealing adhesive layer 140 close to the light emitting device layer 120 to the edge of the light emitting device layer 120.
When the smaller vertical distance a from the edge of the light emitting device layer 120 to the edge of the frame sealing adhesive layer 140 is equal to the set distance, the size of the non-display area of the display panel can be reduced, thereby reducing the bezel size of the display device including the display panel provided by the embodiment.
