[0029] This embodiment provides a display panel packaging structure with good packaging effect, which can prevent pixel shrinkage and avoid crushing the organic light-emitting layer 31.

[0030] like Figure 1 and Figure 2 As shown, the display panel packaging structure includes a packaging plate 1, a water absorption frame 2 and a glass substrate 3. The water absorption frame 2 is arranged around the packaging plate 1 to form a packaging space 21, and the water absorption frame 2 is used to dry the packaging space 21, so that by providing the water absorption frame 2, the pixel shrinkage of the display panel packaging structure can be prevented, and there is no need to provide a drying sheet on the packaging plate 1, so as to avoid the drying sheet being easily attached to the side due to limited space during the operation of the machine, thereby affecting the packaging effect and causing poor packaging.

[0031] Among them, the glass substrate 3 is arranged on the water absorption frame 2, and the glass substrate 3 and the packaging plate 1 are arranged oppositely, and an organic light-emitting layer 31 is arranged on one side of the glass substrate 3, and the organic light-emitting layer 31 is located in the packaging space 21, so that the glass substrate 3 and the packaging plate 1 are connected by setting the water absorption frame 2, and the manpower and cost spent on etching grooves on the packaging plate 1 are saved under the premise of preventing the organic light-emitting layer 31 from being crushed. Optionally, the packaging plate 1 is a transparent glass plate, so that when a drying sheet is not arranged on the packaging plate 1, the display panel packaging structure can form a transparent screen without being blocked. Further optionally, UV glue 4 is arranged between the packaging plate 1 and the water absorption frame 2, and between the glass substrate 3 and the water absorption frame 2, so that the water absorption frame 2 can be bonded and connected to the packaging plate 1 and the glass substrate 3 respectively through the UV glue 4, thereby improving the connection stability.

[0032] Furthermore, the water absorption frame 2 includes a support portion 22 and a water absorption portion 23, wherein the support portion 22 is located on the outside of the water absorption frame 2, and the water absorption portion 23 is located on the inside of the water absorption frame 2, so that the support portion 22 on the outside can support the packaging board 1 and the glass substrate 3, and the water absorption portion 23 on the inside can dry the packaging space 21. Specifically, a desiccant is arranged in the water absorption portion 23, so that the desiccant can absorb the water vapor inside the packaging space 21 to prevent the pixel shrinkage of the display panel packaging structure. Optionally, the color of the support portion 22 is black, so that the black support portion 22 can absorb light to prevent the bright edge phenomenon from appearing on the side of the display panel packaging structure. At the same time, by replacing the grooves etched on the packaging board 1 with the water absorption frame 2 having a black portion, the painting process in the subsequent process can be reduced, and rework and customer complaints caused by insufficient coating, excessive coating, and missing coating can be prevented, thereby saving labor costs. Further optionally, the organic light-emitting layer 31 and the water absorption frame 2 are arranged at intervals, so that a space is left between the organic light-emitting layer 31 and the water absorption frame 2 to prevent the water absorption frame 2 from affecting the organic light-emitting layer 31, wherein the organic light-emitting layer 31 and the water absorption frame 2 are arranged at intervals to prevent the UV glue 4 from adhering to the organic light-emitting layer 31.

[0033] Furthermore, the glass substrate 3 includes an organic light-emitting display area 32, the organic light-emitting layer 31 is arranged in the middle of the organic light-emitting display area 32, and the water absorption frame 2 surrounds the outside of the organic light-emitting display area 32, so that the display uniformity of the display panel packaging structure can be improved. At the same time, the glass substrate 3 also includes a bonding area 33, so that the wire bonding can be facilitated by setting the bonding area 33, and part of the water absorption frame 2 is located between the organic light-emitting display area 32 and the bonding area 33, so that the organic light-emitting display area 32 and the bonding area 33 are separated by the water absorption frame 2. Among them, the bonding area 33 is provided with a driving chip 34, so that the display quality of the display panel packaging structure can be improved by the driving chip 34.
