[0034] In view of the color difference problem caused by mixing masks from different batches when the masks are actually used, this embodiment provides a mask 100 by analyzing the root cause of the color difference of the masks. The mask 100 provided in this embodiment adopts reverse thinking and weakens the visual effect of the color difference of the masks by reducing the size of the single mask units of different batches mixed, thereby improving the color difference existing in the actual application of the masks.

[0035] See also Figure 1 and Figure 3 In one embodiment, the mask 100 includes a plurality of mask units from different batches, and the mask units are provided with a plurality of lamp holes 13 arranged in an array, and each lamp hole 13 passes through two opposite surfaces of the mask unit, and the lamp holes 13 are used to install lamp beads of the display module, and the projection area of ​​the mask unit projected on the display module is less than or equal to 1 / 8 of the cross-sectional area of ​​the display module.

[0036] The multiple mask units are mask units from different batches, that is, the batch number of the multiple mask units is greater than 1, wherein different batches of mask units refer to mask units produced under any conditions such as different temperatures, different humidities, or different molds. The mask unit is roughly a square mask unit, such as a rectangular mask unit or a square mask unit, and each mask unit is provided with a plurality of lamp holes 13 for installing lamp beads, and the plurality of lamp holes 13 are roughly arranged in a square array, and each lamp hole 13 passes through two opposite surfaces of the mask unit; the lamp beads can be LED lamp beads, and the LED lamp beads include a lamp bead bracket and a lamp bead body arranged on the lamp bead bracket. The specific structure of the lamp bead bracket and the specific installation method of the lamp bead body are not limited here. During assembly, one LED lamp bead is installed in one lamp hole 13, and its installation method can be selected as snap-on, interference fit, screw fixation or other reasonable and effective methods. The projection area of ​​the mask unit projected on the display module is less than or equal to 1 / 8 of the cross-sectional area of ​​the display module. In this way, the size of the mask unit is relatively small. When the mask 100 assembled from multiple mask units of different batches is applied to the display module, the mask unit occupies a relatively small proportion of the area of ​​the entire display module. In this way, it is not easy for the human eye to compare and distinguish the difference between the mask 100 on the display module, that is, the color difference of the mask 100 is effectively improved.

[0037] The technical solution of this embodiment reduces the size of the mask unit in the mask 100, so that the mask unit occupies a relatively small area ratio of the entire display module. In this way, even if the mask 100 is assembled using mask units from different batches, it is not easy for the human eye to compare and distinguish the difference between the mask 100 on the display module when watching the display screen from a distance, that is, the color difference of the mask 100 is effectively improved, and the abnormal shadow of the mask bulge can also be improved. Since the mask 100 can be assembled using mask units from multiple different batches, it can effectively improve the color difference of the mask supplier's inventory, thereby improving the timeliness of the mask supply. In addition, since the size of the mask unit is small, the thermal expansion and contraction of the mask unit is small, which can effectively reduce the stress of the mask on the lamp beads and reduce the risk of pulling and cold soldering. In addition, since the size of the mask unit is small, the opening accuracy of the mask unit is higher, which can effectively improve the abnormality of indoor product leakage lamp feet.

[0038] In an optional embodiment, the mask unit is a square mask unit, and the side length of the mask unit is less than or equal to 31.25 mm.

[0039] Specifically, when the mask unit is a rectangular mask unit, the maximum side length (i.e., the long side) of the mask unit is less than or equal to 31.25 mm, and when the mask unit is a square mask unit, the side length of the mask unit is less than or equal to 31.25 mm. In this way, the size of the mask unit is relatively small. When the mask 100 assembled from a plurality of mask units of different batches is applied to the display module, the mask unit occupies a relatively small area ratio of the entire display module, so that it is not easy for the human eye to compare and distinguish the difference of the mask 100 on the display module, that is, the color difference of the mask 100 is more effectively improved.

[0040] See also Figure 3 In one embodiment, the mask unit is provided with twelve lamp holes 13, and the twelve lamp holes 13 are arranged in four rows and three columns. In this embodiment, the mask unit only covers 12 lamp beads, and the size is relatively small. When the mask 100 assembled by using a plurality of mask units of different batches is applied to the display module, the mask unit occupies a relatively small area ratio of the entire display module, so that it is not easy for the human eye to compare and distinguish the difference of the mask 100 on the display module, that is, the color difference of the mask 100 is effectively improved.

[0041] See also Figure 5 In another embodiment, the mask unit is provided with four lamp holes 13, and the four lamp holes 13 are arranged in two rows and two columns. In this embodiment, the mask unit only covers four lamp beads and is relatively small in size. When the mask 100 assembled from a plurality of mask units of different batches is applied to the display module, the mask unit occupies a relatively small area ratio of the entire display module, so that it is not easy for the human eye to distinguish the difference between the mask 100 on the display module, that is, the color difference of the mask 100 is effectively improved.

[0042] See also Figure 6 In another embodiment, the mask unit is provided with eight lamp holes 13, and the eight lamp holes 13 are arranged in four rows and two columns. In this embodiment, the mask unit only covers 8 lamp beads and is relatively small in size. When the mask 100 assembled from a plurality of mask units of different batches is applied to the display module, the mask unit occupies a relatively small area ratio of the entire display module, so that it is not easy for the human eye to distinguish the difference between the mask 100 on the display module, that is, the color difference of the mask 100 is effectively improved.

[0043] See also Figure 7In another embodiment, the mask unit is provided with 24 lamp holes 13, and the 24 lamp holes 13 are arranged in six rows and four columns. In this embodiment, the mask unit only covers 24 lamp beads, and the size is relatively small. When a mask 100 mixed with a plurality of mask units of different batches is applied to a display module, the mask unit occupies a relatively small area ratio of the entire display module, so that it is not easy for the human eye to distinguish the difference between the mask 100 on the display module, that is, the color difference of the mask 100 is effectively improved.

[0044] It should be noted that, in the above embodiment, the specific size of the mask unit is determined according to the actual size and spacing of the lamp beads (ie, the lamp holes 13).

[0045] In an optional embodiment, the center distance between two adjacent lamp holes 13 is 1 mm to 10 mm (such as 1 mm, 1.9 mm, 2.6 mm, 3.9 mm, 4.8 mm, 5 mm, 10 mm and an interval value between any two end point values).

[0046] In an optional embodiment, a buckle 14 is provided on the inner wall of the lamp hole 13, and the buckle 14 is used to be snap-fitted with the lamp bead of the display module. The lamp bead and the mask unit are fixed by snap-fitting, which is easy to operate and relatively firm to install.

[0047] like Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, in some specific embodiments, the lamp hole 13 is a square hole, and a group of opposite inner walls of the lamp hole 13 are provided with buckles 14, which can be optionally card blocks, and corresponding card slots are provided on the opposite sides of the lamp bead bracket of the lamp bead. During assembly, the card blocks can be correspondingly connected to the card slots.

[0048] Optionally, the left and right side surfaces of the clamping block in the installation moving direction are provided with guide chamfers, and the surface of the clamping block in contact with the lamp bead is a plane, and the setting of the guide chamfers can play a role in guiding and aligning the installation.

[0049] In some specific embodiments, the mask unit includes a unit body 11 and a plurality of unit bosses 12, wherein the plurality of unit bosses 12 are arranged in an array on a surface of the unit body 11, and there is a gap between two adjacent unit bosses 12, the unit boss 12 includes four connected side portions, and the four side portions enclose a first lamp hole section, and the unit body 11 is provided with a second lamp hole section corresponding to the first lamp hole section, and the second lamp hole section passes through two opposite surfaces of the unit body 11, and the first lamp hole section and the second lamp hole section together form a lamp hole 13, and the buckle 14 is arranged on the inner wall of the second lamp hole section.

[0050] In this embodiment, the unit body 11 is roughly in the shape of a plate, the unit boss 12 is in a square ring structure, and a plurality of unit bosses 12 are arranged in a square array on the same side surface of the unit body 11, and there is a gap between two adjacent unit bosses 12, and the gaps are the same. The four side portions of the unit boss 12 are all in the shape of a plate, and have the same size, and are sequentially connected end to end to form a square ring structure together. The four side portions enclose a first lamp hole section, and the second lamp hole section penetrates the two opposite surfaces of the unit body 11 along the thickness direction of the unit body 11. Since the lamp hole 13 is a square hole, the first lamp hole section and the second lamp hole section are both square holes. The clamping block is convexly arranged on a group of opposite inner walls of the second lamp hole section, so that the stability of the buckle 14 can be ensured, and then the clamping firmness of the mask 100 and the lamp bead can be ensured.

[0051] See also Figure 4 In one embodiment, the surfaces of the four side portions facing away from the unit body 11 are all formed with concave arc surfaces. Such a configuration not only facilitates the installation operation of the lamp beads, but also reduces the production cost to a certain extent.

[0052] In some specific embodiments, the mask 100 is made of plastic, and the unit body 11 and the multiple unit bosses 12 are integrally formed, that is, the entire mask unit is integrally formed and can be obtained through mold production, which is convenient for mass production, and the overall firmness of the mask unit is better.

[0053] This embodiment also proposes a display module, which includes a light board, a plurality of lamp beads and a mask 100. The specific structure of the mask 100 refers to the above embodiment. Since this display module adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, a plurality of lamp beads are arranged in an array on the light board, and a plurality of mask units of the mask 100 are mounted on the surface of the light board facing the lamp beads, and each lamp bead is placed in a corresponding lamp hole 13.

[0054] Specifically, the lamp board is a PCB board, the lamp beads can be LED lamp beads, the LED lamp beads include a lamp bead bracket and a lamp bead body arranged on the lamp bead bracket, the lamp bead bracket is fixed on the PCB lamp board, and its fixing method can be selected from gluing, soldering or other reasonable fixing methods, the lamp bead bracket is provided with card slots on opposite sides, and a group of inner walls of the lamp hole 13 are provided with buckles 14, and during assembly, the buckles 14 are snapped into the corresponding card slots, so that the lamp beads can be snapped and fixed. The number of mask units can be determined according to the area of ​​the actual display screen, and the batch number of mask units is greater than or equal to 1, that is, mask units of different batches can be mixed and pasted on the surface of the lamp board to assemble the mask 100. When multiple mask units are mixed, two adjacent mask units are abutted, that is, there is no gap between the two adjacent mask units, so that there is no obvious splicing gap between the mask units, which effectively avoids the appearance of bright and dark lines on the display screen to affect the display effect of the display screen.

[0055] Of course, in some other embodiments, the LED lamp bead is a two-in-one or N-in-one structure (where N is an integer greater than 2), that is, two or N lamp bead bodies are arranged on a lamp bead bracket, and accordingly, the hole walls of the lamp holes 13 corresponding to the mask unit on both sides of the lamp bead bracket are provided with buckles 14, and the buckles 14 are fixed to the card grooves on both sides of the lamp bead bracket.

[0056] In some specific embodiments, the sizes of the multiple mask units are the same, that is, for the same lamp board, the sizes of the multiple mask units mounted are the same. Specifically, a plurality of mask units with two rows and two columns of lamp holes 13 can be selected to be assembled into the mask 100, or a plurality of mask units with four rows and two columns of lamp holes 13 can be selected to be assembled into the mask 100, or a plurality of mask units with four rows and three columns of lamp holes 13 can be selected to be assembled into the mask 100, or a plurality of mask units with six rows and four columns of lamp holes 13 can be selected to be assembled into the mask 100, or a plurality of mask units of other sizes can be assembled into the mask 100, all of which are within the protection scope of the present embodiment.

[0057] In some embodiments, the batch number among the four adjacent mask units of any mask unit is greater than or equal to 2.

[0058] Specifically, see Figure 1 and Figure 2, the plurality of mask units include a plurality of first mask units 1, a plurality of second mask units 2, a plurality of third mask units 3 and a plurality of fourth mask units 4, the structures and sizes of the first mask units 1, the second mask units 2, the third mask units 3 and the fourth mask units 4 are the same, and the specific structural settings of the mask units in the above embodiments can be referred to, and will not be described one by one here. The first mask unit 1, the second mask unit 2, the third mask unit 3 and the fourth mask unit 4 can all be selected as mask units with four rows and three columns of lamp holes 13, and the first mask unit 1, the second mask unit 2, the third mask unit 3 and the fourth mask unit 4 are mask units of different batches, and a plurality of first mask units 1, a plurality of second mask units 2, a plurality of third mask units 3 and a fourth mask unit 4 are mixed and assembled into a mask 100, and the specific arrangement of the mask units is: in the four adjacent mask units of any mask unit, the batch number is 2, 3 or 4.

[0059] like Figure 1 As shown, the mask unit in the second row and second column is the third mask unit 3, and the four mask units adjacent to the third mask unit 3 are the second mask unit 2 (adjacent on the upper side), the first mask unit 1 (adjacent on the left side), the second mask unit 2 (adjacent on the lower side) and the first mask unit 1 (adjacent on the right side). Among the four adjacent mask units, two groups of mask units are from the same batch, that is, among the four adjacent mask units, there are mask units from two different batches.

[0060] The mask unit in the second row and third column is the first mask unit 1, and the four mask units adjacent to the first mask unit 1 are the third mask unit 3 (adjacent on the upper side), the third mask unit 3 (adjacent on the left side), the first mask unit 1 (adjacent on the lower side) and the second mask unit 2 (adjacent on the right side). Two of the four adjacent mask units are from the same batch, and the other two mask units are from different batches, that is, three of the four adjacent mask units are from different batches.

[0061] The mask unit in the second row and fourth column is the second mask unit 2, and the four mask units adjacent to the second mask unit 2 are the second mask unit 2 (adjacent on the upper side), the first mask unit 1 (adjacent on the left side), the third mask unit 3 (adjacent on the lower side) and the first mask unit 1 (adjacent on the right side). Two of the four adjacent mask units are from the same batch, and the other two mask units are from different batches, that is, three of the four adjacent mask units are from different batches.

[0062] The fifth column of the second row is the first mask unit 1. The four mask units adjacent to the first mask unit 1 are the third mask unit 3 (adjacent on the upper side), the second mask unit 2 (adjacent on the left side), the first mask unit 1 (adjacent on the lower side) and the fourth mask unit 4 (adjacent on the right side). These four adjacent mask units are from different batches, that is, there are 4 mask units from different batches among the four adjacent mask units.

[0063] In the display module of the present embodiment, the actual use of the mask unit may not be affected by batches, and mask units from different batches may be used to assemble into the mask 100, which can effectively improve the mask supplier's concerns about color difference in stock, thereby improving the timeliness of mask supply. Moreover, since the size of the mask unit is small, the color difference of the mask 100 can be effectively improved, and the abnormal shadow of the mask bulge can also be improved. Moreover, since the size of the mask unit is small, the thermal expansion and contraction of the mask unit is small, which can effectively reduce the stress of the mask on the lamp beads and reduce the risk of pulling and cold soldering. In addition, since the size of the mask unit is small, the opening accuracy of the mask unit is higher, which can effectively improve the abnormality of leaking lamp feet in indoor products.

[0064] In a preferred embodiment, Figure 2 As shown, the specific arrangement of the mask units is: the batch number of the four adjacent mask units of any mask unit is 4. In this way, the color difference worry of mask suppliers in stocking can be more effectively improved, thereby improving the timeliness of mask supply.

[0065] Of course, in some other embodiments, the specific arrangement of the mask units may also be other reasonable arrangements, as long as the batch number of the four adjacent mask units of any mask unit is greater than or equal to 2.

[0066] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
