The application is described in detail below with reference to the attached drawings and alternative embodiments.

Fig. 1 is a schematic view of a display panel according to the present application, fig. 2 is a schematic view of a pixel module according to the present application, and referring to fig. 1-2, a display panel 200 is disclosed, wherein the display panel 200 includes a plurality of pixel modules 200a and an assembly module 100, the pixel modules 200a are detachably disposed on the assembly module 100, a plurality of sub-pixels (R, G, B) are disposed on each of the pixel modules 200a, and the assembly module 100 is used for automatically assembling a plurality of the pixel modules 200a onto the assembly module 100; the pixel module 200a includes a first magnetic attraction structure 220 and a substrate 210, wherein the first magnetic attraction structure 220 is disposed on the substrate 210; the assembly module 100 includes a carrier plate 110 and a plurality of second magnetic structures 120, the plurality of second magnetic structures 120 are arranged on the carrier plate 110 in an array, and the plurality of first magnetic structures 220 and the plurality of second magnetic structures 120 are aligned one by one to make the plurality of pixel modules 200a arranged on the carrier plate 110 in an array.

The application carries out modularized design on the pixels in the display panel 200, so that each pixel module 200a is independently designed and can be detachably arranged on the bearing plate 110, and the damaged pixel module 200a can be directly replaced in the subsequent repairing process, thereby reducing the repairing difficulty and prolonging the service time of the display panel 200. And by arranging the magnetic attraction structure on each pixel module 200a, the magnetic attraction structure corresponds to the magnetic attraction structure on the assembly module 100 one by one, so that the assembly of the pixel modules 200a is realized. The carrier plate 110 is provided with a magnetic attraction structure corresponding to each pixel module 200a, so that each pixel module 200a can be accurately installed, and the alignment installation can be automatically realized by utilizing the magnetic attraction effect. In addition, for the pixel modules 200a with a large number, the second magnetic structures 120 on the carrier plate 110 realize automatic arrangement of the pixel modules 200a, so as to save assembly time and increase production speed of the display panel 200.

Specifically, the plurality of pixel modules 200a are automatically aligned and disposed on the carrier 110 by the following means.

In this embodiment, the carrier plate 110 is provided with a plurality of protrusions 111, and the plurality of protrusions 111 are arranged in an array, and are respectively arranged in a one-to-one correspondence to the areas where the pixel modules 200a are required to be arranged. A groove 211 is provided on the substrate 210 of the pixel module 200a, the groove 211 is provided on a side of the substrate 210 near the carrier plate 110, and the shape of the protrusion 111 is matched with that of the groove 211, so that the protrusion 111 can be embedded in the groove 211 to fix the pixel module 200a.

In this embodiment, alignment and fixing of each pixel module 200a is performed by the cooperation of the protrusion 111 and the groove 211. On the one hand, mainly for positioning, the manner of the protrusions 111 and the grooves 211 can more easily realize that each pixel module 200a is accurately located at a corresponding position, so that each pixel module 200a just falls in a plurality of pixel areas on the carrier plate 110 to realize orderly arrangement; on the other hand, the protrusions 111 are also provided on the carrier plate 110 to prevent the pixel modules 200a from being placed reversely, i.e., the surface where the grooves 211 are not provided is disposed close to the carrier plate 110, and the pixel modules 200a cannot be disposed corresponding to the carrier plate 110, thereby having a problem of preventing reverse arrangement.

The protrusion 111 is preferably a circular protrusion 111, and the recess 211 is a circular recess 211. Of course other shapes of grooves 211, such as square grooves 211, etc. may be suitable.

It is understood that the positions of the protrusion 111 and the recess 211 may be interchanged, for example, a plurality of recesses 211 are provided on the carrier plate 110, and the substrate 210 of the pixel module 200a is aligned and matched in a manner of providing the protrusion 111, which is also included in the scope of the present application. Of course, the recess 211 is provided on the pixel module 200a, and the protrusion 111 is provided on the carrier plate 110, and unevenness may be exhibited on the carrier plate 110 due to the presence of the protrusion 111, and the pixel module 200a may not be stably placed on the carrier plate 110 due to the protrusion 111. After the grooves 211 of the pixel module 200a are matched with the protrusions 111, the pixel module 200a can be smoothly placed on the carrier plate 110.

In another embodiment, a plurality of grooves 211 may be further provided on each pixel module 200a, and a plurality of protrusions 111 may be provided corresponding to each pixel module 200a mounting area on the carrier plate 110. In the case where the plurality of protrusions 111 are provided, the protrusion 111 in this embodiment may have a smaller size than the protrusion 111 in the above-described embodiment, so that the non-groove 211 area under the pixel module 200a is larger than the groove 211 area. It can be appreciated that the plurality of grooves 211 in the present embodiment can be matched with the grooves 211 in the above embodiment to form a better accurate alignment.

The depth of the recess 211 may be less than half the thickness of the substrate 210 on the pixel module 200a, and the substrate 210 in this embodiment may be a flexible substrate 210. A buffer structure is disposed on the side of the flexible substrate 210 with the recess 211, so as to play a role in buffering when the pixel module 200a is aligned with the carrier 110.

In one embodiment, the first magnetic structure 220 includes a first magnet 221, where the first magnet 221 is disposed on a side of the substrate 210 near the assembly module 100 and is disposed in the recess 211; the second magnetic structure 120 includes a second magnet 121, and a plurality of protrusions 111 are formed on the carrier plate 110 by a plurality of the second magnets 121; the protrusion 111 is engaged with the recess 211, and the first magnet 221 and the second magnet 121 are attracted to fix the pixel module 200a.

The side of the first magnet 221 near the protrusion 111 may be disposed on the surface of the recess 211, and the recess 211 surface generated by the first magnet 221 is utilized to align with the protrusion 111.

In this embodiment, the first magnet 221 and the second magnet 121 are magnetically engaged, so that each pixel module 200a can be accurately aligned on the carrier plate 110, and the first magnet 221 and the second magnet 121 are engaged with each other, so that the pixel module 200a is fixed on the carrier plate 110. The first magnet 221 and the second magnet 121 have different magnetic properties, specifically, the first magnet 221 may be N-pole, the second magnet 121 may be S-pole, or the first magnet 221 may be S-pole, and the second magnet 121 may be N-pole. The first magnet 221 and the second magnet 121 attract each other so that the pixel module 200a is fixed on the carrier plate 110.

In the present embodiment, the magnetism and magnetic force of the first magnet 221 on each pixel module 200a are the same, and the magnetism of each second magnet 121 on the carrier plate 110 is also the same. In the actual assembly process, since the pixel modules 200a at each position are basically consistent, and the problem that the pixel modules 200a at the edge are different from the middle pixel module 200a does not exist, in the scheme, the pixel modules 200a are aligned on the carrier plate 110 by magnetic attraction and automatic alignment, so that the pixel modules 200a are in one-to-one correspondence with the protrusions 111.

The first magnet 221 and the second magnet 121 mentioned above can automatically align the position of the pixel module 200a on the carrier plate 110 with each pixel module 200a, so as to align the pixel modules 200 a. However, in relative terms, the pixel module 200a may have a problem in that the contact is not completely fitted or only half of the protrusion 111 is fitted into the recess 211 in the fitting relationship with the use of the recess 211 and the protrusion 111. In this regard, the present application also improves the carrier plate 110.

Fig. 3 is a schematic view of the vibration structure of the present application, referring to fig. 3, the assembly module 100 further includes a vibration structure 140, the vibration structure 140 is used for vibrating the carrier plate 110, and the vibration of the carrier plate 110 drives the plurality of pixel modules 200a to vibrate so as to move the pixel modules 200 a.

In this embodiment, the position of the pixel module 200a may be adjusted by vibration, considering that the protrusion 111 and the recess 211 cannot be aligned completely during the magnetic attraction of the first magnet 221 and the second magnet 121. Moreover, by means of vibration, when a large number of pixel modules 200a are integrally placed on the carrier plate 110, the pixel modules 200a can be automatically aligned by utilizing displacement generated by the vibration. The first magnets 221 on the plurality of pixel modules 200a cannot overlap each other under the effect of the like poles, so that a layer of orderly arranged pixel modules 200a is formed.

In an embodiment, the vibration structure 140 mainly drives the carrier plate 110 to vibrate in a direction perpendicular to the plane, and the vibration amplitude is small, but the vibration frequency is high, so as to drive the pixel module 200a on the carrier plate 110 to vibrate up and down. In addition, since the surface of the carrier plate 110 is provided with the plurality of protrusions 111 having an uneven surface, the pixel module 200a is driven to move on the uneven surface during the up-down vibration of the carrier plate 110, so that the grooves 211 on the pixel module 200a exactly correspond to the protrusions 111 on the carrier plate 110. In this solution, the plurality of pixel modules 200a are placed on the carrier plate 110, and the plurality of pixel modules 200a are orderly arranged by vibration, so that the pixel modules 200a can enter the designated position more quickly by adjusting the vibration amplitude and the vibration frequency in the vibration process.

Specifically, the vibration structure 140 includes a motor 141, a bottom plate 143, and a belt 142, the bottom plate 143 is disposed below the carrier plate 110, the motor 141 is provided with at least two, the motor is fixed at one side of the carrier plate 110 near the bottom plate 143, the belt 142 surrounds the two motors 141 and is connected to the bottom plate 143, when the motor 141 rotates, the distance between the two motors 141 and the bottom plate 143 changes, the distance between one motor 141 increases, and the distance between one motor 141 decreases, so that the carrier plate 110 inclines relative to the bottom plate 143. When the motor 141 rotates back and forth, the inclination angle of the bearing plate 110 and the bottom plate 143 changes many times, so as to realize the vibration of the bearing plate 110. It can be appreciated that an elastic component is disposed between the bottom plate 143 and the carrier plate 110, such as a spring in a compressed state, and two ends of the spring respectively abut against the carrier plate 110 and the bottom plate 143, so that when the vibration structure 140 vibrates, a relative displacement occurs between the bottom plate 143 and the carrier plate 110. In this embodiment, by providing a plurality of vibration structures 140, the vibration amplitude of the carrier plate 110 can be larger, which is more beneficial to the movement of the pixel module 200 a.

In another embodiment, the vibration structure 140 may also adopt a vibration motor, and the vibration motor is used to drive the carrier plate 110 to vibrate. However, the vibration motor is relatively small in vibration amplitude but high in frequency.

In another embodiment, the vibration structure 140 is not disposed in the assembly module 100, but disposed in the process module, and the vibration structure can generate the vibration of the carrier plate 110 parallel to the plane direction by the mechanical arm during the assembly process of the display panel 200, so that the pixel module 200a on the carrier plate 110 can fall into the position of the protrusion 111. Specifically, vibration fittings are disposed in the assembly module, for example, an elastic supporting structure is disposed between the bottom plate 143 and the carrier plate 110, and the assembly module 100 is buffered when the bottom plate 143 or the carrier plate 110 is vibrated.

In another embodiment, besides the magnetic attraction mode, the vacuum attraction mode may be adopted to match the protrusion 111 of the pixel module 200a with the groove 211 on the carrier plate 110.

Fig. 4 is a schematic view of the assembly module according to the present application, and referring to fig. 4, the assembly module 100 further includes a vacuum suction structure connected to the plurality of small holes 131 through a vacuum suction pipe 132 and used for sucking air from the small holes 131. The small holes 131 are disposed on the protrusions 111, and at least a plurality of small holes 131 are disposed on the protrusions 111. The pixel module 200a can be fixed by vacuum adsorption without using magnetic attraction, and the vacuum adsorption is relatively speaking, and is not fixed on the substrate 210 as a magnet, and only the vacuum adsorption pipeline 132 and the small holes 131 are required to be arranged on the bearing plate 110, so that the operation is convenient. And after all the pixel modules 200a are assembled and sealed, the redundant air among the plurality of pixel modules 200a in the modularized design can be sucked out by adopting a vacuum adsorption structure, so that the internal vacuum is realized. For example, in another embodiment, the small holes 131 may be further disposed on the non-protruding 111 area of the carrier plate 110 to vacuumize the interior of the display panel 200.

Specifically, the vacuum suction structure may be implemented by a small vacuum pump, and in the actual display panel 200, the vacuum suction pipe 132 may be provided only on the assembly module, and the small vacuum pump may be externally connected to form vacuum suction on the plurality of pixel modules 200 a.

Whether the pixel module 200a is fixed by vacuum adsorption or the pixel module 200a is fixed by magnetic attraction, after the subsequent assembly is completed, protective glass can be arranged on the pixel modules 200a, and the pixel modules 200a can be protected and fixed by bonding the frame glue and arranging the bearing plate 110 in a box-to-box manner.

Of course, the vacuum adsorption structure and the magnetic attraction can be used in cooperation with each other, so that the completely embedded pixel module 200a is not moved any more under the vibration of the vibration structure 140, and the pixel module 200a without the embedded pixel module 200a continues to move until the vibration is stopped under the conditions that the magnetic attraction and the vacuum attraction of the pixel module 200a are stable.

Since the pixel modules 200a are generally square structures, there may be a plurality of pixel modules 200a having different rotation angles, that is, the rotation angles of the pixel modules 200a along the direction perpendicular to the substrate 210 and the rotation axes along the center of the pixel modules 200a are generally 360 degrees, and in this case, only a few angles may cause the square pixel modules 200a to be aligned, for example, so that the pixel modules 200a need to be aligned in the direction parallel to the plane of the display panel 200.

Fig. 5 is a schematic top view of a display panel according to a second embodiment of the present application, fig. 6 is a schematic cross-sectional view of the display panel according to the second embodiment of the present application, fig. 7 is a schematic top view of a pixel module according to the second embodiment of the present application, and fig. 8 is a schematic cross-sectional view of the pixel module according to the second embodiment of the present application. Referring to fig. 5-8, another design of the first magnetic attraction structure 220 and the second magnetic attraction structure 120 is proposed in this embodiment based on the above embodiment. Specifically, the present application relates to a method for manufacturing a semiconductor device.

The first magnetic attraction structure 220 includes a third magnet 222 and a fourth magnet 223, the third magnet 222 is magnetically different from the fourth magnet 223, the second magnetic attraction structure 120 includes a fifth magnet 122 and a sixth magnet 123, and the fifth magnet 122 is magnetically different from the sixth magnet 123; the two third magnets 222 are respectively disposed at one side of the pixel module 200a, and the two fourth magnets 223 are respectively disposed at the other side of the pixel module 200 a.

The four sides of the carrying plate 110 are further provided with a first side plate 112, a second side plate 113, a third side plate 114 and a fourth side plate 115, the opposite sides of the first side plate 112 and the third side plate 114 are provided, the opposite sides of the second side plate 113 and the fourth side plate 115 are provided, two fifth magnets 122 are respectively arranged on the first side plate 112 and the third side plate 114, and two sixth magnets 123 are respectively arranged on the second side plate 113 and the fourth side plate 115.

In the outermost plurality of pixel modules 200a, the third magnet 222 and the fourth magnet 223 are magnetically attracted to the fifth magnet 122 and the sixth magnet 123, respectively, to fix the plurality of pixel modules 200a; the adjacent pixel modules 200a are magnetically fixed by the third magnet 222 and the fourth magnet 223.

In the present application, in the actual assembly process, the pixel modules 200a are fixed to the side plates by mounting the outermost pixel modules 200a and using the fifth magnet 122 or the sixth magnet 123 on the side plates and the third magnet 222 or the fourth magnet 223 on the pixel modules 200a, and the adjacent pixel modules 200a can also be fixed by the magnetic attraction between the third magnet 222 and the fourth magnet 223. After the outermost pixel modules 200a are fixed, a new magnetic field is formed on the inward side (i.e., the side facing away from the side plate) of the outermost pixel modules 200a, and the functions of the fifth magnet 122 and the sixth magnet 123 are similar to those of the side plate. A circle of pixel modules 200a is installed using the magnetic field of the new vehicle of the outermost pixel module 200a to form a circle of pixel modules 200a of the sub-outer layer. All pixel modules 200a are aligned together by outside-in by a circle-by-circle assembly. In this process, each pixel module 200a may be positioned exactly at a predetermined position and the pixel module 200a may be fixed in cooperation with the above-mentioned vacuum adsorption manner. After the installation is completed, detecting whether the pixel module 200a of the whole display panel 200 is lighted (the process is needed by external equipment), and repairing the pixel module 200a which is not installed and has damage; after the repair is completed, the cover glass is installed, the vacuum pump and the vibration structure 140 are turned off, and the installation is completed.

In this scheme, can also set up the scheme that magnetic strength ladder was changed to the magnetic force of the outside is strongest, and from outside to inside, magnetic force progressively decreases.

It should be noted that, the fifth magnet and the sixth magnet at the side of the carrier plate are elongated, and the length of the fifth magnet and the sixth magnet may be equal to the length of the side of the carrier plate. Or a plurality of fifth magnets or sixth magnets, wherein each of the fifth magnets or sixth magnets is magnetically fixed to each of the pixel modules by a corresponding number of magnets of the pixel module rows and columns. When two pixel modules need to be magnetically attracted and fixed, the adjacent side of one pixel module needs to be provided with the same magnetism under the conditions that the adjacent side of the other pixel module is provided with the different magnetism and the adjacent side of the bearing plate is provided with the different magnetism.
