Description

Technical Field

[0001] Multiple embodiments of the present specification relate to the field of printing technology, and specifically to a method and device for printing special-shaped retaining walls, and a method and device for printing special-shaped dams. Background Art

[0002] The application of enclosure structure printing technology is now quite widespread, especially in the edge area of ​​the display module, where the application of dam printing is particularly important (the dam is the middle frame structure). This dam design provides effective dust, water and collision protection for the circuits in the display module, improving the protection performance of the overall device.

[0003] In the field of electronic devices, such as mobile phones and tablets, in order to improve the aesthetics and feel of the product, the sides of the outer shell are often designed in an arc shape. However, the dam structure on the internal circuit board is usually set vertically, and this design is difficult to perfectly fit the arc contour of the outer shell, thus forming a gap between the two. The existence of these gaps limits the effect of the dam structure in dustproof, waterproof and collision prevention. Therefore, the demand for printing of special-shaped enclosure structures has emerged, especially the demand for applying special-shaped enclosure structure printing to dam structure printing.

[0004] Furthermore, for special-shaped enclosure structures, the degree of restoration of the final printed shape to the designed shape is crucial for product application. For example, inside mobile phones and tablets, if the enclosure structure can achieve a higher degree of fit with the outer shell, its protective performance will be significantly improved, thereby ensuring the stable operation of the device in complex environments.

[0005] In view of this, there is an urgent need for a method that can accurately print special-shaped enclosure structures. Summary of the invention

[0015] In a second aspect, an embodiment of the present specification provides a method for printing a special-shaped dam, comprising: Printing a first special-shaped enclosure wall on a display module based on the special-shaped enclosure wall printing method described in the first aspect of the embodiment; Printing a second special-shaped enclosure wall on the display module based on the special-shaped enclosure wall printing method described in the first aspect of the embodiment; Material is filled between the first special-shaped enclosure wall and the second special-shaped enclosure wall to obtain a special-shaped enclosure dam.

[0016] In a third aspect, an embodiment of this specification provides a printing device for a special-shaped enclosure wall, based on the printing method for a special-shaped enclosure wall described in the first aspect of the above embodiment, comprising: The first acquisition module is used to acquire the three-dimensional space model of the special-shaped enclosure wall, and perform layering processing on the three-dimensional space model in the vertical direction to obtain a plurality of enclosure layers stacked in sequence from bottom to top, and acquire the layer height information corresponding to each enclosure layer; The second acquisition module is used to acquire the enclosure routes corresponding to each enclosure layer in the horizontal direction, and there is a deviation in the enclosure routes of at least one pair of adjacent enclosure layers in the multiple enclosure layers stacked sequentially from bottom to top; The printing module is used to print multiple enclosure layers in sequence from bottom to top on the printing surface in a stacked manner through a print head based on the layer height information corresponding to each enclosure layer and the enclosure route corresponding to each enclosure layer, so as to print special-shaped enclosure walls. In the process of printing the special-shaped enclosure wall, there is no step of adjusting the angle of the printing surface in the pitch angle direction and the roll angle direction.

[0017] In a fourth aspect, an embodiment of the present specification provides a printing device for a special-shaped dam, including the printing device for a special-shaped retaining wall as described in the third aspect of the above embodiment.

[0018] In a fifth aspect, an embodiment of the present specification provides a display device, comprising a special-shaped dam printed by the special-shaped dam printing method described in the second aspect of the embodiment.

[0019] In a sixth aspect, an embodiment of the present specification provides an electronic device, comprising a processor and a memory; the processor is connected to the memory; the memory is used to store executable program code; the processor runs a program corresponding to the executable program code by reading the executable program code stored in the memory, so as to execute the steps described in the first aspect or the second aspect of the above embodiment.

[0020] In a seventh aspect, an embodiment of the present specification provides a computer storage medium, wherein the computer storage medium stores a plurality of instructions, wherein the instructions are suitable for being loaded by a processor and executing the steps described in the first aspect or the second aspect of the above embodiment.

[0021] The beneficial effects brought by the technical solutions provided by some embodiments of this specification include at least: Based on the layer height information corresponding to each enclosure layer and the enclosure route corresponding to each enclosure layer, the special-shaped enclosure wall is printed by stacking and printing layer by layer, and in the process of printing the special-shaped enclosure wall, there is no step of adjusting the angle of the printing surface in the pitch angle direction and the roll angle direction. Not only is a printing scheme for special-shaped enclosure walls provided, but also the adjustment angle calculation of the printing surface in the pitch angle direction and the roll angle direction is avoided during the printing process. The angle adjustment calculation in these two directions to adapt to the shape change of the special-shaped enclosure wall is relatively complicated and prone to errors. Therefore, the printing scheme for the special-shaped enclosure wall provided in the embodiment of this specification can improve the printing accuracy of the special-shaped enclosure wall.

[0022] Since there is no step to adjust the angle of the printing surface in the pitch and roll directions in the process of printing the special-shaped enclosure wall by stacking layers, when the upper enclosure layer is printed in real time, the printing material of the upper enclosure layer may be partially suspended above the printing material of the lower enclosure layer. If the curing operation is not performed in time, the deformation problem of the printing material will be more serious, which will lead to the deviation between the final printed shape of the special-shaped enclosure wall and the desired design shape. Therefore, in the process of printing the special-shaped enclosure wall, the printing line is synchronously cured in real time to improve the stability of the special-shaped enclosure wall, thereby improving the restoration of the shape of the special-shaped enclosure wall.

[0023] The enclosure route of the bottom enclosure layer in the horizontal direction can be known in advance according to the printing requirements, and the extension direction vector information corresponding to each adjacent enclosure layer can also be known in advance based on the design parameters of the special-shaped enclosure wall. Further, based on the corresponding layer height information of each enclosure layer, the corresponding extension direction vector information between each adjacent enclosure layer, and the enclosure route of the bottom enclosure layer in the horizontal direction, the enclosure route corresponding to each enclosure layer in the horizontal direction can be obtained. The enclosure route corresponding to each enclosure layer in the horizontal direction obtained in this way is more accurate, which further improves the restoration degree of the shape of the special-shaped enclosure wall.

[0024] In order to adapt to the application product design requirements of the special-shaped enclosure wall, there may be slight height differences at different positions on the top contour line of the special-shaped enclosure wall; in addition, there may also be slight height differences at different positions on the printing surface. Therefore, it is necessary to layer the three-dimensional space model in the vertical direction based on the first height data set of the top contour line of the three-dimensional space model and / or the second height data set of the bottom contour line of the three-dimensional space model to obtain multiple enclosure layers stacked from bottom to top, so as to achieve a more reasonable layering operation.

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of this specification will be described clearly and completely below in conjunction with the drawings in the embodiments of this specification.

[0042] The terms "first", "second", "third", etc. in the description and claims of this specification and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0043] The following description provides examples and does not limit the scope, applicability or examples set forth in the claims. Changes may be made to the functions and arrangements of the elements described without departing from the scope of the present specification. Various processes or components may be appropriately omitted, substituted or added to each example. For example, the described method may be performed in an order different from the order described, and various steps may be added, omitted or combined. In addition, features described with respect to some examples may be combined in other examples.

[0044] Reference Figure 1 As shown, Figure 1 A schematic flow chart of a method for printing a special-shaped enclosure wall provided in an embodiment of this specification, the method for printing a special-shaped enclosure wall may at least include: Step 102: Obtain a three-dimensional space model of the special-shaped enclosure wall, and perform layer processing on the three-dimensional space model in the vertical direction to obtain a plurality of enclosure layers 3 stacked in sequence from bottom to top, and obtain the layer height information corresponding to each enclosure layer 3 (Note: the layer height indicates the height of the enclosure layer 3 in the vertical direction); Step 104: acquiring the enclosure routes corresponding to each enclosure layer 3 in the horizontal direction, and at least one pair of adjacent enclosure layers 3 among the multiple enclosure layers 3 stacked sequentially from bottom to top has deviation in the enclosure routes in the horizontal direction; Step 106, based on the layer height information corresponding to each enclosure layer 3 and the enclosure route corresponding to each enclosure layer 3, a plurality of enclosure layers 3 are printed in sequence from bottom to top on the printing surface 1 in a stacked manner by the print head to print a special-shaped enclosure wall, and in the process of printing the special-shaped enclosure wall, there is no step of adjusting the angle of the printing surface 1 in the pitch angle direction and the roll angle direction.

[0045] It should be noted that by adjusting the angle of the printing surface 1 in the pitch angle direction and the roll angle direction, the printing of special-shaped enclosure walls can be achieved (Note: by changing the angle of the printing surface 1 in the pitch angle direction and the roll angle direction, the angle between the print head and the horizontal plane can be changed, thereby achieving the printing of special-shaped enclosure walls), and the adhesion of the upper enclosure layer to the lower enclosure layer can be ensured to be better (Note: the upper enclosure layer can be completely attached to the lower enclosure layer, thereby avoiding the upper enclosure layer being partially suspended above the lower enclosure layer). However, the calculation complexity for this angle adjustment is high, so it is easy to produce errors, and the errors are large.

[0046] In the printing method of the special-shaped enclosure wall provided in multiple embodiments of this specification, based on the layer height information corresponding to each enclosure layer 3 and the enclosure route corresponding to each enclosure layer 3, the special-shaped enclosure wall is printed by stacking and printing layer by layer, and in the process of printing the special-shaped enclosure wall, there is no step of adjusting the angle of the printing surface 1 in the pitch angle direction and the roll angle direction. The printing of the special-shaped enclosure wall is achieved only by controlling the translation and height adjustment of the printing surface 1 and / or the print head (Note: at most the angle adjustment of the printing surface 1 in the heading angle direction is increased). Therefore, not only a printing scheme for the special-shaped enclosure wall is provided, but also the adjustment angle calculation of the printing surface 1 in the pitch angle direction and the roll angle direction is avoided during the printing process. Therefore, the printing scheme for the special-shaped enclosure wall provided in the embodiments of this specification can improve the printing accuracy of the special-shaped enclosure wall and improve the restoration of the shape of the special-shaped enclosure wall.

[0047] It should also be noted that during the printing process, in addition to printing along the horizontal enclosure routes corresponding to each enclosure layer 3, it is also necessary to combine the layer height information corresponding to each enclosure layer 3 to control the printing height when printing each enclosure layer 3.

[0048] In multiple embodiments of the present specification, during the process of printing the special-shaped enclosure wall, the printing circuit is synchronously cured in real time.

[0049] Since there is no step to adjust the angle of the printing surface 1 in the pitch angle direction and the roll angle direction in the process of printing the special-shaped enclosure wall by stacking layers, when the upper enclosure layer is printed in real time, the printing material of the upper enclosure layer may be partially suspended from the printing material of the lower enclosure layer (Note: because the upper enclosure layer may be offset in the horizontal direction compared to the lower enclosure layer). If the curing operation is not performed in time, the deformation problem of the printing material will be more serious, which will lead to the deviation between the final printed shape of the special-shaped enclosure wall and the desired design shape. Therefore, in the process of printing the special-shaped enclosure wall, the printing line is synchronously cured in real time to improve the stability of the special-shaped enclosure wall, thereby improving the restoration degree of the shape of the special-shaped enclosure wall.

[0050] Reference Figure 2As shown, in multiple embodiments of this specification, the step of obtaining the enclosure routes corresponding to each enclosure layer 3 in the horizontal direction includes: Step 202, obtaining the enclosure route of the bottom enclosure layer 3 in the horizontal direction (a plane coordinate system is established with the printing surface 1 as the horizontal plane, and each position on the enclosure route has a corresponding position coordinate in the plane coordinate system); Step 204: Obtain the extension direction vector information corresponding to each of the two adjacent enclosure layers 3. The extension direction vector information includes a plurality of extension direction vectors that can reflect the extension conditions of the enclosure surface composed of the two adjacent enclosure layers 3 at a plurality of extension positions. Figure 3 , Figure 4 As shown, the entire enclosure wall has multiple extension lines 2 from bottom to top. The extension direction vector is a vector representing the extension between two adjacent enclosure layers 3, which is a part of the extension line 2. The extension direction vector can be referred to Figure 6 As shown, it should be noted that the extension direction vector can be obtained according to the design parameters of the special-shaped retaining wall); Step 206, based on the corresponding layer height information of each enclosure layer 3, the corresponding extension direction vector information between each adjacent enclosure layer 3, and the enclosure route of the bottom enclosure layer 3 in the horizontal direction, obtain the corresponding enclosure route of each enclosure layer 3 in the horizontal direction (Note: the specific calculation principle will be explained in the following embodiments).

[0051] It is necessary to add that Figure 3 and Figure 4 It shows a special-shaped case of a special-shaped retaining wall. Figure 5 Another special-shaped case of a special-shaped retaining wall is shown.

[0052] in, Figure 3 and Figure 4 The special-shaped retaining wall shown is a truncated cone-shaped cylindrical structure that shrinks inward as a whole. Figure 5 The special-shaped enclosure wall shown in the figure has different degrees of tilting on the enclosure route. That is, the special-shaped enclosure wall printing method described in multiple embodiments of this specification can print various styles of special-shaped enclosure wall structures.

[0053] Reference Figure 7 As shown, in multiple embodiments of the present specification, based on the layer height information corresponding to each enclosure layer 3, the extension direction vector information corresponding to each adjacent enclosure layer 3, and the enclosure route of the bottom enclosure layer 3 in the horizontal direction, the enclosure route corresponding to each enclosure layer 3 in the horizontal direction is obtained, including: Step 702: the bottommost enclosure layer 3 among all enclosure layers 3 is regarded as the lower enclosure layer, and the upper enclosure layer 3 of the bottommost enclosure layer 3 among all enclosure layers 3 is regarded as the upper enclosure layer; Step 704: based on the enclosure route of the current lower enclosure layer, the corresponding extension direction vector information between the current lower enclosure layer and the current upper enclosure layer, the layer height information corresponding to the current lower enclosure layer and / or the layer height information corresponding to the current upper enclosure layer, obtain the enclosure route of the current upper enclosure layer; Step 706, when the enclosure layer 3 of the latest obtained enclosure route is not the top enclosure layer among all the enclosure layers 3, the enclosure layer 3 of the latest obtained enclosure route is regarded as the new lower enclosure layer, and the enclosure layer 3 above the enclosure layer 3 of the latest obtained enclosure route is regarded as the new upper enclosure layer, and the step of obtaining the enclosure route of the current upper enclosure layer is returned based on the enclosure route of the current lower enclosure layer, the corresponding extension direction vector information between the current lower enclosure layer and the current upper enclosure layer, the layer height information corresponding to the current lower enclosure layer and / or the layer height information corresponding to the current upper enclosure layer.

[0054] It should be noted that the enclosure route of the bottommost enclosure layer 3 among all the enclosure layers 3 can be obtained based on the actual setting position of the special-shaped enclosure wall on the printing surface 1, and further, the enclosure route corresponding to each enclosure layer 3 can be obtained in turn by a layer-by-layer recursive method.

[0055] Reference Figure 8 As shown, in multiple embodiments of the present specification, the acquisition of the enclosure route of the current upper enclosure layer based on the enclosure route of the current lower enclosure layer, the corresponding extension direction vector information between the current lower enclosure layer and the current upper enclosure layer, the layer height information corresponding to the current lower enclosure layer and / or the layer height information corresponding to the current upper enclosure layer includes: Step 802: Based on the corresponding extension direction vector information between the current lower enclosure layer and the current upper enclosure layer, the layer height information corresponding to the current lower enclosure layer, and / or the layer height information corresponding to the current upper enclosure layer, calculate the horizontal offset direction and offset distance corresponding to each of the multiple enclosure positions on the enclosure route of the current lower enclosure layer required to obtain the enclosure route of the current upper enclosure layer; Step 804, based on the position coordinates corresponding to each of the multiple enclosure positions on the enclosure route of the current lower enclosure layer and the calculated offset directions and offset distances in the horizontal direction corresponding to each of the multiple enclosure positions on the enclosure route of the current lower enclosure layer required to obtain the enclosure route of the upper enclosure layer, obtain the enclosure route of the current upper enclosure layer.

[0056] Please refer to Figure 3 As shown, the special-shaped enclosure wall has corresponding extension lines 2 at different positions (Note: the extension line 2 can show the shape change of the special-shaped enclosure wall in the height direction, and Figure 3 Only 8 extension lines are shown as an example), so for the two enclosure layers 3 distributed up and down, there are also multiple extension direction vectors at different positions of the two.

[0057] Furthermore, based on the corresponding extension direction vector information between the lower enclosure layer and the upper enclosure layer, the layer height information corresponding to the current lower enclosure layer, and the layer height information corresponding to the current upper enclosure layer, the horizontal offset direction and offset distance corresponding to each of the multiple enclosure positions on the enclosure route of the current lower enclosure layer required to obtain the enclosure route of the current upper enclosure layer can be calculated (Note: the specific calculation principle is explained in the following embodiments).

[0058] Reference Fig. 9 As shown, in multiple embodiments of the present specification, based on the corresponding extension direction vector information between the current lower enclosure layer and the current upper enclosure layer, the layer height information corresponding to the current lower enclosure layer and / or the layer height information corresponding to the current upper enclosure layer, the offset direction and offset distance in the horizontal direction corresponding to each of the multiple enclosure positions on the enclosure route of the current lower enclosure layer required to obtain the enclosure route of the current upper enclosure layer are calculated, including: Step 902: Based on the corresponding extension direction vector information between the current lower enclosure layer and the current upper enclosure layer, obtain the horizontal components of the multiple extension direction vectors in the corresponding extension direction vector information between the current lower enclosure layer and the current upper enclosure layer and the angles with the horizontal plane; Step 904, based on the horizontal components in the horizontal direction and the angles with the horizontal plane of multiple extension direction vectors in the extension direction vector information corresponding to the current lower enclosure layer and the current upper enclosure layer, the layer height information corresponding to the current lower enclosure layer and / or the layer height information corresponding to the current upper enclosure layer, calculate the horizontal offset directions and offset distances corresponding to multiple enclosure positions on the enclosure route of the current lower enclosure layer required to obtain the enclosure route of the current upper enclosure layer.

[0059] Reference Figure 6 As shown, Figure 6 The calculation principle of calculating the horizontal offset direction and offset distance corresponding to a certain enclosure position on the enclosure route of the lower enclosure layer required for obtaining the enclosure route of the upper enclosure layer is exemplified: First, according to the design parameters of the special-shaped retaining wall, we can obtain Figure 6 The extension direction vector between the middle and lower enclosure layers and the upper enclosure layer, and then the horizontal component of the extension direction vector is obtained. Based on the horizontal component of the extension direction vector, the horizontal offset direction of the upper enclosure layer compared to the lower enclosure layer can be known; Furthermore, the angle θ between the extension direction vector and the horizontal plane can be known according to the extension direction vector; Furthermore, the height difference △H between the upper enclosure layer and the lower enclosure layer is obtained (Note: Figure 6The height difference △H of the enclosure layer is calculated based on the middle position of the enclosure layer height. Therefore, when the upper enclosure layer height is consistent with the lower enclosure layer height, the enclosure layer height difference △H can be considered as the upper enclosure layer height or the lower enclosure layer height. When the upper enclosure layer height is inconsistent with the lower enclosure layer height, the enclosure layer height difference △H can be considered as the average value of the sum of the upper enclosure layer height and the lower enclosure layer height; when the enclosure layer height difference △H is calculated based on the top of the enclosure layer, the enclosure layer height difference △H can be directly considered as the upper enclosure layer height); Finally, the horizontal offset distance △L of the upper enclosure layer compared to the lower enclosure layer can be obtained based on the angle θ and the enclosure layer height difference △H.

[0060] According to the above logic, the horizontal offset direction and offset distance corresponding to each of the multiple enclosure positions on the enclosure route of the current lower enclosure layer required to obtain the enclosure route of the current upper enclosure layer can be calculated. Therefore, based on the enclosure route of the lower enclosure layer, the enclosure route of the upper enclosure layer can be obtained.

[0061] In addition, it can be understood that in order to avoid the upper enclosure layer being too suspended outside the lower enclosure layer, in multiple embodiments of the present specification: for any pair of adjacent enclosure layers 3, the horizontal offset distance △L corresponding to any enclosure position on the lower enclosure layer is less than a preset threshold, and the preset threshold can be a preset proportion of the width of the lower enclosure layer.

[0062] Therefore, based on the above calculation principle, for any pair of adjacent enclosure layers 3, the height difference between the two adjacent enclosure layers 3 and the angle θ between any enclosure position on the lower enclosure layer and the horizontal plane should all meet the following conditions: The height difference of the enclosure layer △H / tanθ≤preset threshold value, and the preset threshold value can be set according to the width of the lower enclosure layer.

[0063] In multiple embodiments of the present specification, before the three-dimensional space model is layered in the vertical direction to obtain multiple enclosure layers 3 stacked in sequence from bottom to top and the height information corresponding to each enclosure layer 3 is obtained, the method further includes: Acquire a first height data set of a top contour line of the three-dimensional space model and / or a second height data set of a bottom contour line of the three-dimensional space model, wherein the first height data set includes height data corresponding to each contour point on the top contour line of the three-dimensional space model, and the second height data set includes height data corresponding to each contour point on the bottom contour line of the three-dimensional space model; The three-dimensional space model is layered in the vertical direction to obtain a plurality of enclosure layers 3 stacked in sequence from bottom to top, including: Based on the first height data set of the top contour line of the three-dimensional space model and / or the second height data set of the bottom contour line of the three-dimensional space model, the three-dimensional space model is layered in the vertical direction to obtain multiple enclosure layers 3 stacked in sequence from bottom to top.

[0064] Reference Figure 4 As shown, in order to adapt to the application product design requirements of the special-shaped enclosure wall, there may be slight height differences at different positions on the top contour line of the special-shaped enclosure wall; in addition, there may also be slight height differences at different positions on the print surface 1. Therefore, it is necessary to perform layered processing on the three-dimensional space model in the vertical direction based on the first height data set of the top contour line of the three-dimensional space model and / or the second height data set of the bottom contour line of the three-dimensional space model to obtain multiple enclosure layers 3 stacked in sequence from bottom to top, so as to achieve a more reasonable layering operation.

[0065] Therefore, in one embodiment of the present specification, obtaining a three-dimensional spatial model of a special-shaped enclosure wall includes: Obtain the design parameters of special-shaped retaining walls; Obtain the enclosure route of the bottom of the special-shaped enclosure wall on the printing surface, and obtain the height data of the enclosure route at the bottom of the special-shaped enclosure wall on the printing surface 1; Based on the height data at the bottom enclosure route of the special-shaped enclosure wall on the printing surface 1 and the design parameters of the special-shaped enclosure wall, a three-dimensional spatial model of the special-shaped enclosure wall is obtained.

[0066] Specifically, refer to Figure 4 , Fig.10 As shown, the three-dimensional space model is layered in the vertical direction based on the first height data set of the top contour line of the three-dimensional space model and / or the second height data set of the bottom contour line of the three-dimensional space model to obtain a plurality of enclosure layers 3 stacked in sequence from bottom to top, including: Step 1002, obtaining a plurality of extension lines 2 that can reflect the extension conditions in the height direction corresponding to different positions of the three-dimensional space model; Step 1004, obtaining height data of contour points 21 on the top contour line of the three-dimensional space model and / or height data of contour points 22 on the bottom contour line of the three-dimensional space model corresponding to each extension line 2; Step 1006: based on the height data of the contour point 21 on the top contour line of the three-dimensional space model and / or the height data of the contour point 22 on the bottom contour line of the three-dimensional space model corresponding to each extension line 2, each extension line 2 is segmented to obtain a plurality of segmentation points 23 corresponding to each extension line 2; Step 1008, obtaining the level data corresponding to each of the segmentation points 23 on the corresponding extension line 2; Step 1010: Based on the hierarchical data of all the segmentation points 23 on the corresponding extension line 2, the segmentation points 23 belonging to the same level are respectively connected to obtain multiple layering lines 24 of the three-dimensional space model (Note: it can be understood that all the segmentation points 23 located in the first level are connected by fitting lines, all the segmentation points 23 located in the second level are connected by fitting lines, and so on); Step 1012: Based on the multiple layering lines 24 of the three-dimensional space model, the three-dimensional space model is layered in the vertical direction to obtain multiple enclosure layers 3 stacked in sequence from bottom to top.

[0067] The segmentation process of each extension line 2 is performed based on the height data of the contour point 21 on the top contour line of the three-dimensional space model and / or the height data of the contour point 22 on the bottom contour line of the three-dimensional space model corresponding to each extension line 2, so as to obtain a plurality of segmentation points 23 corresponding to each extension line 2, which can be but not limited to any one of the following modes: Mode 1: For each extension line 2, it is divided into the same number of segments, and for the same extension line 2, the height difference between any two adjacent segmentation points 23 thereon is the same, and the height difference between any two adjacent segmentation points 23 on different extension lines 2 may be different. In this mode, the entire special-shaped enclosure wall can be completely divided into multiple enclosure layers 3 without any redundant structure, so the entire special-shaped enclosure wall can be printed continuously. However, it should be noted that in this mode, since the layer heights at various positions of the enclosure layer 3 may be inconsistent, the printing parameters may need to be adjusted in real time when printing each enclosure layer 3 (Note: in this mode, the layer height information of the enclosure layer obtained needs to include the layer height information corresponding to each enclosure position of the enclosure layer).

[0068] Mode 2: A preset height is preset, and each extension line 2 is segmented based on the preset height. Therefore, for all extension lines 2, the height difference between any two adjacent segmentation points 23 is the preset height. In this mode, during the printing process of each enclosure layer 3, the layer height at each position of the enclosure layer 3 is consistent, so the enclosure layer 3 can be printed continuously. However, it should be noted that in this mode, there may be excess parts at the top of each extension line 2 that do not reach the preset height, so they need to be printed separately.

[0069] In addition to the above two modes, there are many other layering modes, which can be set according to printing requirements. They are not described here one by one.

[0070] It should also be noted that the layer height control of the enclosure layer 3 can be achieved by adjusting the discharge speed of the print head, the movement speed of the print head and / or the printing surface 1.

High thixotropic materials are selected for printing, and glue dispensing is performed with follow-up curing. The glue dispensing adopts a pneumatic glue dispensing valve and a ceramic needle, and the follow-up curing device adopts a ring light; Step eight: fill the material between the inner and outer dams to form a filling layer 6. After the filling is completed, let it stand for a preset time and solidify again to complete the production of the middle frame structure.

[0078] LED backlight refers to a backlight technology that uses light emitting diodes (LEDs) as light sources. This technology is widely used in display devices such as liquid crystal displays and LCD TVs to illuminate the back of the display screen so that the screen can display images. It is usually necessary to set up multiple LED lights. However, in actual application, it is found that due to the influence of the light intensity at the edges of the LED lights, the middle position of the multiple LED lights is often too dark or too bright, that is, the abnormal brightness area 7 is formed.
