[0043] Figure 1 This is a schematic diagram of the structure of a mask. Figure 1 As shown, the mask plate is usually formed by combining a mask frame 1, a mask member 2 and a metallized mask strip 3. The mask frame 1 includes a frame body 11 and a supporting mask structure 12. The mask member 2 is attached to the frame body 11 and the supporting mask structure 12, and the metallized mask strip 3 is arranged on the side of the supporting mask structure 12 away from the frame body 11.

[0044] like Figure 1 As shown, the frame body 11 is composed of a first frame 111 extending along a first direction and a second frame 112 extending along a second direction orthogonal to the first direction, wherein Figure 1 The first direction is the horizontal direction, and the second direction is the vertical direction. The support mask structure 12 is arranged within the range surrounded by the frame body 11, and includes a first support bar 121 extending along the first direction and a second support bar 122 extending along the second direction, and the first support bar 121 and the second support bar 122 overlap to form a grid structure, and each grid structure corresponds to each display panel to be divided on the substrate. The evaporation mask strip 3 is provided with an evaporation opening 31, corresponding to the grid structure, which is used to deposit evaporation materials on thin films (such as luminescent material films, etc.) of specific shapes and patterns that need to be formed on the display panel. Accurate deposition of thin film layers of specific shapes and patterns

[0045] In a specific implementation process, the mask member 2 can be used as a shielding mask strip 21 and / or an alignment mask strip 22. When the mask member 2 is used as a shielding mask strip 21, the member body of the mask member 2 can be attached to at least one of the first support strip 121 and the second support strip 122 in the support mask structure 12. The figure takes the attachment of the member body to the second support strip 122 in the support mask structure 12 as an example for explanation, so that the supporting force of the support mask structure 12 can be further improved. When the mask member 2 is used as an alignment mask strip 22, the member body is attached to at least one of the first frame 111 and the second frame 112. Among them, the functions of the alignment mask strip 22 include: on the one hand, ensuring the position alignment between the substrate and the mask plate when using the mask plate for evaporation process or deposition process; on the other hand, it is also used as an alignment mark for the subsequent fixed setting of the supporting mask structure 12, the shielding mask strip 21, and the metallized mask strip 3, thereby improving the alignment accuracy between the supporting mask structure 12 and each mask strip, and reducing the alignment error between the supporting mask structure 12 and each mask strip.

[0046] However, it is found during use that when the support member and the mask frame 1 are fitted together, spot welding and bonding are usually performed at some places instead of welding and bonding the entire contact surface of the two. As a result, the areas between the support member and the mask frame 1 that are not welded or bonded are not firmly fitted, and there will be gaps. After the mask is used, liquid is likely to remain in the gaps, making it difficult to clean.

[0047] Therefore, in order to solve the above technical problems, the present invention provides the following technical solutions.

[0048] Figure 2 is a structural schematic diagram of a mask component according to an embodiment of the present invention, such as Figure 2 As shown, a leakage area A is provided on the component body of the mask component 2, and a leakage hole is provided in the leakage area A, and the leakage hole is located in the area where the component body overlaps with the first support bar 121 and / or the second support bar 122, or, is located in the area where the component body overlaps with the first frame 111 and / or the second frame 112. In this way, even if the component body and the mask frame 1 are not firmly attached to form a gap, when the mask plate formed by the mask component 2 and the mask frame 1 is cleaned, the liquid remaining in the gap can also flow out from the leakage hole, thereby reducing the residual liquid and improving the display performance of the display panel.

[0049] In a specific implementation process, the number of leakage areas A can be set to multiple according to actual conditions, and the spacing between the multiple leakage areas A can be configured as follows:

[0050] The first type is that the plurality of liquid leakage areas A include a plurality of second-type liquid leakage areas A2, and at least part of the component body is provided with the second-type liquid leakage areas A2 in the projection area on the grid structure.

[0051] Specifically, see Figure 3 ,in, Figure 3 is a structural schematic diagram of a mask plate according to an embodiment of the present invention, such as Figure 3 As shown, in the mask plate, the mask member 2 is described by taking the shielding mask strip 21 and the alignment mask strip 22 as an example. Figure 3 The description is made by taking the one-to-one correspondence between the position of the leakage hole and the projection area of ​​the component body in each grid structure as an example. In practice, the leakage hole may also be provided in the area of ​​the component body corresponding to the projection area of ​​part of the grid structure.

[0052] However, after the leakage holes are opened in the second type of leakage area A2, the stress of the component body will be affected. When the second type of leakage area A2 corresponds to the projection area of ​​the grid structure, since there is no support bar in the first direction, in order to ensure the stress of the component body and not affect the overall support force of the subsequent mask to be formed, the area of ​​the second type of leakage area A2 is not easy to be too large. In this way, the number of leakage holes opened is relatively small, resulting in poor liquid discharge effect. Therefore, the present invention can also adopt a second method to set the leakage area A:

[0053] The second type, the plurality of liquid leakage areas A comprises a plurality of first-type liquid leakage areas A1, and at least a portion of the overlapping area between the first support bar 121 and the second support bar 122 is aligned with the first-type liquid leakage area A1.

[0054] Specifically, see Figure 4 ,in, Figure 4 is another structural schematic diagram of a mask according to an embodiment of the present invention, such as Figure 4 As shown, in the mask plate, the mask member 2 is described by taking the shielding mask strip 21 and the alignment mask strip 22 as an example. Figure 4 The example of setting the first type of liquid leakage area A1 in the overlapping area of ​​each first support bar 121 and each second support bar 122 is used for explanation. In practice, the first type of liquid leakage area A1 can also be set in the partially overlapping area. In this way, due to the presence of the first support bar 121 in the first direction, when the area of ​​the first type of liquid leakage area A1 is set relatively large, when the stress of the component body is small, the overall support force of the mask is relatively small, and when the area of ​​the first type of liquid leakage area A1 is large, more liquid leakage holes can be opened, which makes it easier to discharge the liquid, and the liquid discharge effect is better.

[0055] In a specific implementation process, under the condition that the overall support force of the mask is met, a third method can also be used to set the leakage area A:

[0056] The third type: setting the first type of leakage area A1 and the second type of leakage area A2 at the same time:

[0057] Specifically, see Figure 5 ,in, Figure 5 is another structural schematic diagram of a mask according to an embodiment of the present invention, Figure 5 The scheme shown is Figure 3 and Figure 4 The combination of the above-mentioned related contents can be referred to the above-mentioned related records, which will not be repeated here. Among them, the number of various leakage areas A can be set according to actual needs.

[0058] In a specific implementation process, the leakage area can be evenly arranged on the mask component 2 according to the actual required stress, stress concentration position, material, size and other factors of the component body, and the leakage area A is rectangular, diamond or circular as a whole. Figures 7a to 7c As shown. The leakage holes in the leakage area A are arranged in an array, and the shape of each leakage hole is set to be circular, elliptical, rectangular, diamond or rectangular with chamfered corners, such as Figure 8 As shown. For a circular leakage hole, the hole diameter may be 0.6 mm. For an ellipse, rectangle, diamond or chamfered rectangle, the length of the opening may be 0.6 mm and the width may not exceed 0.6 mm.

[0059] It should be noted that the above-mentioned opening sizes are only exemplary. In actual applications, openings of sizes that meet usage requirements can be opened according to actual needs.

[0060] The mask component 2 of this embodiment is provided with a leakage area A on the component body and a leakage hole in the leakage area A. Thus, even if the component body and the mask frame 1 are not firmly attached to each other and a gap is formed, the liquid remaining in the gap can flow out from the leakage hole during cleaning, thereby reducing the residual liquid and improving the display performance of the display panel.

[0061] In a specific implementation process, the frame body 11 is provided with alignment marks of the mask member 2, so that the accuracy of the mask plate formed subsequently can be guaranteed. The alignment marks include alignment marks for shielding the mask strip 21 and alignment marks for aligning the mask strip 22.

[0062] Continue to see Figure 2 When the mask component 2 is a shielding mask strip 21, the shielding mask strip 21 further includes a first alignment hole B. When the shielding mask strip 21 is attached to the corresponding support strip, the first alignment hole B and the alignment mark of the shielding mask strip 21 can be used to align the shielding mask strip 21 to ensure the bonding accuracy of the shielding mask strip 21 and the corresponding support strip. When the mask component 2 is an alignment mask strip 22, the alignment mask strip 22 further includes a second alignment hole C. When the alignment mask strip 22 is attached to the corresponding frame, the second alignment hole C and the alignment mark of the alignment mask strip 22 can be used to align the alignment mask strip 22 to ensure the bonding accuracy of the alignment mask strip 22 and the corresponding frame.

[0063] In a specific implementation process, when the mask member 2 is an alignment mask strip 22, it is usually necessary to set the alignment mask strip 22 on both the left and right second frames 112. In order to make the alignment mask strip 22 no longer distinguish the left and right frames, the second alignment hole C in this embodiment includes:

[0064] A first sub-alignment hole C1 at one end and a second sub-alignment hole C2 at the other end are respectively arranged along the extension direction of the alignment mask strip 22, wherein the first sub-alignment hole C1 is closer to the one end than the leakage area A, and the second sub-alignment hole C2 is closer to the other end than the leakage area A; the first sub-alignment hole C1 and the second sub-alignment hole C2 are symmetrically distributed about the central axis in a direction perpendicular to the extension direction of the alignment mask strip.

[0065] The third sub-alignment hole C3 and the fourth sub-alignment hole C4 are arranged in the area between the first sub-alignment hole C1 and the second sub-alignment hole C2, wherein in the direction perpendicular to the extension direction of the alignment mask strip 22, the third sub-alignment hole C3 and the fourth sub-alignment hole C4 are arranged on both sides of the leakage area A. The distance from the third sub-alignment hole C3 to the central axis of the extension direction of the alignment mask strip 22 is the same as the distance from the fourth sub-alignment hole C4 to the central axis of the extension direction of the alignment mask strip 22. The distance between the two can be a minimum of 4 mm and a maximum of 6 mm.

[0066] In this way, for the alignment mask strip 22, there are corresponding sub-alignment holes at the top, bottom, left and right, and the left and right sub-alignment holes have no effect on alignment and evaporation. Therefore, the alignment mask strip 22 does not need to be distinguished between left and right, reducing the risk of design errors.

[0067] In a specific implementation process, in order to avoid the problem of large amounts of material preparation and inventory stagnation due to the incompatibility of the alignment mask strip 22 and the shielding mask strip 21, in this embodiment, the mask component 2 also includes a first alignment hole B and a second alignment hole C, so that the mask component 2 can be used as an alignment mask strip 22 or a shielding mask strip 21 according to actual needs.

[0068] In a specific implementation process, for the shielding mask strip 21, the welding area between it and the frame body 11 usually requires a narrower size. Therefore, a half-etching line L can be set on the component body according to different project requirements. When the mask component 2 is used as a shielding mask strip 21, the unnecessary parts can be cut along the half-etching line L so that the mask component 2 can be formed into a desired shape.

[0069] Specifically, see Figure 2 , the half-etched line L is located at both ends of the mask member 2, wherein the half-etched line L includes a first portion and a second portion, and in a direction perpendicular to the extension direction of the mask member 2, the first portion and the second portion are arranged on both sides of the alignment hole of the mask member 2. The first portion and the second portion are both in the shape of a fold line, and the angle of the fold line is a right angle or an obtuse angle. Figure 2 In the example of right angle, when the angle between the broken lines is an obtuse angle, you can refer to Figure 6a , Figure 6aFIG. 1 is another schematic diagram of the structure of the mask component according to an embodiment of the present invention. Figure 2 As for the mask structure 2 shown in FIG. 1 , since the angle of the fold line is a right angle, the stress thereof is relatively large, and when the portion corresponding to the half-etched line L is removed, the mask structure 2 is easily damaged. Figure 6a As for the mask member 2 shown, Figure 6a The angle of the fold line in is an obtuse angle, and its stress is relatively small. When removing the portion corresponding to the half-etched line L, the mask structure 2 is easily damaged. Among them, the corners of the fold line can be reinforced by dispensing glue to prevent the half-etched line L from being easily knocked off when used as an alignment mask strip 22. Among them, multiple half-etched lines L can be set according to actual needs, and 3 are used as an example in the figure. The distance between the first part and the second part of the three half-etched lines L is 1.6mm, 2.0mm, and 4.0mm in order from narrow to wide.

[0070] In a specific implementation process, if Figure 2 When the mask member 2 shown is used as a shielding mask strip 21, it has an impact on the grid structure of the supporting mask structure 12. Figure 6b The structure of Figure 6b FIG. 1 is another structural schematic diagram of a mask member according to an embodiment of the present invention. Figure 6b and Figure 2 As shown, the mask member 2 and Figure 2 The difference of the mask member 2 shown is that the half-etching line L extends from one end to the other end along the extension direction of the mask member 2, wherein the half-etching line L includes a first part and a second part, and in a direction perpendicular to the extension direction of the mask member 2, the first part and the second part are arranged on both sides of the alignment hole of the mask member 2, so that the overall width of the mask member 2 can be reduced to avoid affecting the grid structure supporting the mask structure 12.

[0071] Furthermore, the present invention also provides a method for preparing a display panel, wherein the method for preparing a display panel utilizes the mask of the above-mentioned embodiment to deposit film layers such as a luminescent material layer of the display panel. The detailed preparation process can refer to the existing related technology and will not be repeated here.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
