[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] like Figure 1 As shown, the present application relates to a packaging sheet, a display module and a display screen. The packaging sheet includes: a first area 10, on which a second area 20 corresponding to the effective display area of ​​the substrate for packaging the effective display area is arranged; the first area 10 refers to a packaging area, which can cooperate with the substrate to achieve a good packaging effect. By sequentially and orderly arranging a plurality of second areas 20 on the first area 10, and the plurality of second areas 20 respectively correspond to the effective display area of ​​the substrate, a good display and packaging effect can be ensured.

[0034] The first area 10 is also provided with a third area 30 corresponding to the non-effective display area of ​​the substrate and used to encapsulate the non-effective display area; the third area 30 is opened on one side of the second area 20, and the third area 30 corresponds to the non-effective display area of ​​the substrate, and is used to encapsulate the non-effective display area; thereby achieving a good coordination effect with the non-effective display area.

[0035] The area corresponding to the lead area of ​​the non-effective display area in the third area 30 is completely hollowed out. By eliminating the waste area in the area corresponding to the lead area of ​​the non-effective display area, that is, the waste area is completely hollowed out, it is possible to avoid waste peeling and glass debris remaining after waste cutting; at the same time, since the waste area is hollowed out, the waste peeling process can be omitted, thereby improving the working efficiency.

[0036] The present application adopts the method of eliminating the packaging sheet waste in the area corresponding to the lead, which means that the lead is completely exposed to the outside, and the risk of lead scratching can be completely avoided. Since there is no waste, the operating efficiency can be significantly improved.

[0037] It can be seen from the above description that the present application achieves the following technical effects:

[0038] In the embodiment of the present application, a completely hollowed-out method is adopted, and the area corresponding to the lead area of ​​the non-effective display area in the third area 30 is completely hollowed out, so as to achieve the purpose of eliminating the waste area on the packaging sheet, thereby achieving the technical effect of avoiding waste peeling and residual glass fragments after waste cutting, thereby solving the problem that the waste area of ​​the packaging sheet will inevitably touch the lead during the peeling process, and the glass fragments will inevitably remain on the lead during the peeling process, so there is a technical problem that the waste stripping process causes lead scratches in the back-end operation of the module.

[0039] Furthermore, the third area 30 is completely hollowed out by laser or etching process. It is understandable that by completely hollowing out by laser or etching process, a precise molding effect can be achieved, thereby ensuring the effect of removing the waste area.

[0040] Further, the second regions 20 are sequentially arranged in an array at intervals along a preset direction on the first region 10; and the third regions 30 are spaced between adjacent second regions 20 along the first direction. It can be understood that by sequentially arranging a plurality of second regions 20 in an array at intervals on the first region 10, a good coordination effect with other components can be achieved; wherein the preset direction can be arranged in an array in a vertical direction. At the same time, the third region 30 is arranged in a vertical direction between two adjacent groups of second regions 20, which can achieve a good cutting effect. wherein, in the present application, the first direction refers to the vertical direction.

[0041] Further, the length of the third region 30 is at least not less than the total length of the plurality of second regions 20. It is understandable that by making the total length of the third region 30 in the vertical direction not less than the sum of the total lengths of the plurality of second regions 20 in the vertical direction, a good cutting effect can be ensured, thereby avoiding the occurrence of a cutting omission area. Preferably, the length of the third region 30 is greater than the total length of the plurality of second regions 20. A certain cutting margin can be provided, thereby achieving a sufficient cutting effect.

[0042] Further, grooves 40 are respectively provided on both sides of the outermost edge of the second region 20 and along the first direction. It can be understood that by providing grooves 40 on both sides of the outermost edge of the second region 20, specifically on the left side of the second region 20 on the leftmost side in the figure and on the right side of the second region 20 on the rightmost side in the figure, and along the first direction, a good separation effect can be achieved. In this application, the first direction refers to the vertical direction.

[0043] like Figure 2 As shown, a groove 50 is provided in the second region 20. It can be understood that by providing the groove 50 in the second region 20, a good packaging effect can be achieved.

[0044] Furthermore, the depth of the groove 50 is 0.25-0.3 mm. It can be understood that a good packaging effect can be ensured.

[0045] like Figure 3 As shown, a plurality of alignment holes 60 are respectively provided on and around the first area 10. It can be understood that a good alignment effect can be achieved, thereby achieving a good positioning effect. Preferably, the number of the plurality of alignment holes 60 is three. The three alignment holes 60 are respectively provided at three points around the first area 10.

[0046] The encapsulation sheet of this application adopts the following operation steps:

[0047] 1. The encapsulation sheet is cleaned before feeding;

[0048] 2. Glue dispensing on packaging sheet;

[0049] 3. Press the package and substrate together.

[0050] Cutting steps:

[0051] 1. Cut the package surface and split it first;

[0052] 2. Cut the display surface and split the slices; the package slices can be facing upward after cutting, which is convenient for subsequent process operations;

[0053] 3. After being cut, the semi-finished single-chip display products are loaded into pallets and transferred to the next station.

[0054] The utility model also has the following beneficial effects:

[0055] 1. No waste and corresponding processes; for example, because the anode substrate and the encapsulation sheet are cut manually, there is waste from the encapsulation sheet that needs to be peeled off in the early stage; it can realize the effect of automatic connection, cleaning and loading into trays for large-scale cutting and continuous operation, saving manpower.

[0056] 2. Reduce the difficulty of operation for operators; for example, after a large substrate of 370*470mm is cut into a single display with more than 1,000 modules, the waste stripping operation takes more than 1 hour, and the difficulty of stripping the waste varies with product size and thickness. Some models cannot be stripped due to UV overflow or the waste stripping of a single screen takes more than 1 minute.

[0057] 3. Suitable for laser cutting, further improving the operating efficiency and higher tolerance requirements; in the early stage, due to the existence of waste, laser cutting will damage the leads at the bottom of the package waste, so wheel cutting is required. The tolerance of wheel cutting is generally 0.2mm, while that of laser cutting is 0.05mm; therefore, the application of this solution has a significant effect on improving the production efficiency and quality.

[0058] The present application also relates to a display module, including a packaging sheet. The basic principle and technical effects of the display module using the packaging sheet provided in this embodiment are the same as those of the above embodiment. For parts not mentioned in this embodiment, please refer to the above corresponding contents.

[0059] The present application also relates to a display screen, comprising the display module as described above.

[0060] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings; however, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical scheme of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
