Referring to fig. 1 and 2, a display screen 20 (see fig. 6) according to an embodiment of the present invention is provided for displaying various information such as text, images, and videos. This display screen 20 includes face guard 10 and light-emitting component, and light-emitting component includes circuit board and lamp pearl. The lamp pearl can be fixed on the circuit board through paster welded mode, and the circuit board is roughly flat-plate-shaped, and the quantity of lamp pearl is a plurality of, and a plurality of lamp pearl intervals set up on the same surface of circuit board. For example, the lamp beads are distributed and orderly arranged on the circuit board in a matrix of a plurality of rows and a plurality of columns. The shape of the bead may be substantially rectangular parallelepiped, square, ellipsoid or spherical, as the case requires.
The lamp bead can be (Light Emitting Diode) lamp bead for LED lamp bead has following advantage: first, do not have ultraviolet ray and infrared ray in the spectrum of the light ray that lamp pearl institute sent, the discarded object can be retrieved moreover, does not have pollution elements such as mercury, for the green cold light source that can safe touch, and the glare is little and radiationless. And secondly, the service life of the lamp bead is long, and the lamp bead has stronger anti-vibration capability. And thirdly, the light color changes are various, and colorful dynamic change effects and various patterns can be realized. Therefore, when the LED lamp beads are adopted, the environmental protection performance, the safety performance and the display performance of the whole display screen 20 can be improved.
Referring to fig. 1 and 2, in some embodiments, mask 10 includes a body portion 100 and a projection 200, the body portion 100 having a first surface 110 and a second surface 120, the first surface 110 and the second surface 120 facing in opposite directions, e.g., first surface 110 being an upper surface of body portion 100 and second surface 120 being a lower surface of body portion 100. When the face guard 10 is installed on the circuit board, the second surface 120 is used for attaching on the circuit board, the mounting hole 101 has been seted up on this body part 100, the quantity of mounting hole 101 is a plurality of for the quantity of mounting hole 101 equals the quantity of lamp pearl, after the face guard 10 was installed on the circuit board, the lamp pearl then worn to establish in this mounting hole 101, so the arrangement of mounting hole 101 is the same with the arrangement of lamp pearl, and the matrix distribution in multirow multiseriate is arranged in order in the same way promptly for mounting hole 101. The cross-sectional shape of the mounting hole 101 is a square, but the mounting hole 101 may be a rectangle, a circle, an ellipse, a regular polygon, or the like, as needed in the actual situation.
The number of the protrusion portions 200 is plural, the number of the protrusion portions 200 is relatively smaller than the number of the mounting holes 101, the protrusion portions 200 are provided on the first surface 110 of the body portion 100, and the protrusion portions 200 protrude by a set height in the thickness direction (Z-axis direction) of the body portion 100 with respect to the first surface 110. The protrusions 200 are also arranged on the first surface 110 in a matrix arrangement of rows and columns. The protrusion height of the protrusion 200 relative to the first surface 110 is a, where a is in a range of 0.5mm ≤ a ≤ 10mm, and a may be, for example, 0.5mm, 0.6mm, 0.7mm, or 10 mm.
In some embodiments, when the second surface 120 of the body 100 is attached to the circuit board and the lamp bead is inserted into the mounting hole 101, the lower portion of the lamp bead is completely received in the mounting hole 101, the upper portion of the lamp bead is exposed out of the mounting hole 101, and the portion of the lamp bead exposed out of the mounting hole 101 is defined as the exposed portion. Since the exposed portion is exposed outside the mounting hole 101 and located on the side where the first surface 110 is located, the exposed portion also protrudes a set height relative to the first surface 110 along the thickness direction of the main body 100, and the protruding height of the exposed portion relative to the first surface 110 along the thickness direction of the main body 100 is smaller than the protruding height of the protruding portion 200 relative to the first surface 110 along the thickness direction of the main body 100. In other embodiments, the lamp bead may be completely received in the mounting hole 101, for example, the end surface of the lamp bead is completely flush with the first surface 110; as another example, the end surface of the bead is maintained at a distance from the first surface 110.
For assembling the display 20, all the lamp beads must be inserted into the mounting holes 101 during the process of installing the mask 10 on the light emitting module, and the second surface 120 of the main body 100 is tightly attached to the surface of the circuit board. Therefore, when the body 100 is initially installed on the circuit board, the body can roll back and forth on the face mask 10 through the roller, so as to apply a certain pressure to the face mask 10, so that the second surface 120 of the body 100 is tightly attached to the surface of the circuit board, and the lamp beads are perfectly arranged in the installation holes 101. To the face guard 10 of this embodiment, because the protrusion height of the relative first surface 110 of portion that exposes along this body 100 thickness direction is less than the protrusion height of the relative first surface 110 of bellying 200 along this body 100 thickness direction, when adopting the running roller to compress tightly face guard 10, because the interference effect of bellying 200, the running roller can only contact with bellying 200, thereby avoid running roller direct contact lamp pearl, also prevent that the running roller that makes a round trip to roll on face guard 10 directly supports and presses the lamp pearl, make this pressure of supporting can not constitute the destruction to the lamp pearl, ensure the security of display 20 equipment. Further, because the running roller that makes a round trip to roll can not constitute the damage to the lamp pearl, can eliminate the running roller and probably harm the worry of lamp pearl, great pressure can be applyed to event running roller face guard 10, and the rolling speed of running roller can be accelerated simultaneously for face guard 10 installs fast to light-emitting component in the short time on, thereby improves display screen 20's packaging efficiency.
Therefore, the protruding height of the protruding portion 200 relative to the first surface 110 along the thickness direction of the body portion 100 is greater than the protruding height of the exposed portion relative to the first surface 110 along the thickness direction of the body portion 100, so that the phenomenon that the roller presses the lamp bead to damage the lamp bead can be effectively avoided, the rolling speed of the rolling pressure of the roller is increased, the installation efficiency of the face mask 10 on the light-emitting component is increased, and finally the assembly efficiency of the display screen 20 is increased. Due to the fact that the assembly efficiency of the display screen 20 is improved, the large-scale production can be further achieved by improving the productivity of the display screen 20, the production cost of the display screen 20 is reduced on the basis of ensuring the quality, and therefore the market competitiveness of the display screen 20 product is improved.
Referring to fig. 2, 3 and 4, in some embodiments, the body portion 100 includes a plurality of cross members 130 and longitudinal members 140, the cross members 130 and the longitudinal members 140 may have substantially the same shape, the cross members 130 extend along the length direction (X-axis direction) of the mask 10, that is, a single cross member 130 is transversely disposed, meanwhile, a plurality of cross members 130 are spaced along the width direction (Y-axis direction) of the mask 10, and the distance between two adjacent cross members 130 may be equal. The stringers 140 extend in the width direction of the face mask 10, i.e., a single stringer 140 is longitudinally disposed, while a plurality of stringers 140 are spaced apart in the length direction of the face mask 10, and the spacing between two adjacent stringers 140 may be equal. The longitudinal beams 140 and the transverse beams 130 may be connected perpendicularly across each other, and thus the longitudinal beams 140 and the transverse beams 130 are connected to each other such that the body portion 100 has a grid-like shape, i.e., the space between the longitudinal beams 140 and the transverse beams 130 forms the mounting holes 101. The protruding portion 200 is disposed at the intersection between the longitudinal beam 140 and the transverse beam 130, and since the intersection between the longitudinal beam 140 and the transverse beam 130 has a greater structural strength, the connection strength between the protruding portion 200 and the main body portion 100 can be increased, thereby increasing the rigidity of the protruding portion 200. Consequently, at the in-process of running roller roll extrusion, can prevent effectively that the bellying 200 from producing great bending deformation under the effect of pressure, prevent that the running roller from directly applying the pressure to the lamp pearl because of the deformation of bellying 200, avoid the lamp pearl to be harmd by the running roller.
Referring to fig. 2, since the protrusions 200 are arranged in a plurality of rows on the body, two adjacent rows of protrusions 200 can be viewed as one array unit 150, and thus, a plurality of array units 150 are also arranged at intervals in the width direction of the mask 10. Two rows of mounting holes 101 are spaced between two adjacent array units 150. in a popular way, the distance between two adjacent array units 150 is the length of two mounting holes 101 along the width direction of the face mask 10. The number of alignment units 150 is proportional to the overall size of mask 10, and as the length and width of mask 10 increase, the number of alignment units 150 may increase, thereby allowing projections 200 to have a substantially uniform density distribution throughout first surface 110 of body portion 100. The phenomenon that the roller presses the lamp beads to damage the lamp beads due to the fact that the protruding portions 200 are low in distribution density is avoided.
Referring to fig. 1 and 2, each arrangement unit 150 includes two rows of protrusions, wherein one row of protrusions is referred to as a first row of protrusions 151, and the other row of protrusions is referred to as a second row of protrusions 152. For a single arrangement unit 150, the first row of bosses 200 and the second row of bosses 200 are respectively located on two adjacently disposed beams 130, and the bosses 200 in the same row are evenly spaced on the same beam 130, i.e. the distance between the two rows of bosses (151, 152) in the single arrangement unit 150 is the length of one mounting hole 101 along the width direction of the mask 10. For the bosses in the same row, two adjacent bosses 200 are separated by three mounting holes 101, that is, the distance between two adjacent bosses 200 is the length of three mounting holes 101 along the length direction of mask 10, and the distance between two adjacent bosses 200 in the first row of bosses 151 is equal to the distance between two adjacent bosses 200 in the second row of bosses 152. In short, for each row of bosses, two adjacent bosses 200 are equally spaced apart, with the spacing being equal to the length of the three mounting holes 101 along the length of the mask 10.
For two rows of bosses (151, 152) in the same arrangement 150, the outermost boss 200 in the first row of bosses 151 is spaced from the outermost boss 200 in the second row of bosses 152 by one mounting hole 101 along the length of the mask 10, such that the bosses 200 in both the first and second rows of bosses 151, 152 are in a substantially staggered arrangement.
In fact, for all of the bosses 200, arranged at another angle, all of the bosses 200 may be distributed on a limited number of diagonals 160 of different mounting holes 101, which diagonals 160 may be angled at 45 ° to the length of the mask 10. Meanwhile, the protrusion height a of the protrusion 200 with respect to the first surface 110 is 0.5mm to 10 mm. Referring to fig. 6, when the user observes at an acute angle greater than 10 ° with respect to the first surface 110, the user can effectively observe the image and video displayed on the display screen 20 by the lamp beads, so that the arrangement and the protruding height of the protruding portions 200 do not affect the observation, and thus the display screen 20 can be ensured to have a larger observation angle, for example, a 160 ° observation angle of the display screen 20 is realized.
Therefore, the arrangement of the protruding portion 200 can make the density of the protruding portion 200 be substantially the same at all positions of the first surface 110 of the main body 100, which can prevent the manufacturing cost and the material cost of the mask 10 from being increased due to the higher density of the protruding portion 200, prevent the frictional resistance of the roller from being increased due to the excessively high seal of the protruding portion 200, and avoid the adverse effect on the installation efficiency of the mask 10 due to the too slow moving speed of the roller. Meanwhile, the phenomenon that the roller presses the lamp beads to damage the lamp beads due to the fact that the distribution density of the protruding portions 200 is low can be avoided. Further, it is also possible to make the display screen 20 have a large viewing angle such as 160 °.
Referring to fig. 2, 3 and 5, in some embodiments, mask 10 further includes a tab 300, where the tab 300 is located in each of the mounting holes 101, i.e., where each mounting hole 101 has a tab 300 therein, e.g., where each mounting hole 101 has a tab 300 therein, where the tab 300 is attached to an inner wall surface of the mounting hole 101, and where the tab 300 extends a length along the width of the mask 10 relative to the inner wall surface. Of course, the nose 300 has some flexibility. Specifically, for the same row of mounting holes 101, the inner wall surfaces of two adjacent mounting holes 101 for connecting the tabs 300 extend in the longitudinal direction of the mask 10 and are parallel to each other, in other words, the inner wall surfaces extending in the longitudinal direction and parallel to each other are an upper wall surface 101a and a lower wall surface 101b (the inner wall surfaces extending in the width direction and parallel to each other are a left wall surface and a right wall surface), for the same row of mounting holes 101, when the tab 300 in the first mounting hole 101 is connected to the upper wall surface 101a, the tab 300 in the second adjacent mounting hole 101 is connected to the lower wall surface 101b, the tab 300 in the third adjacent mounting hole 101 is connected to the upper wall surface 101a, and so on, that the tabs 300 are alternately arranged on the upper wall surface 101a and the lower wall surface 101b of the mounting hole 101.
Through setting up plush copper 300, when lamp pearl and mounting hole 101 cooperation, plush copper 300 produces elastic deformation and forms certain extrusion force to the lamp pearl for the lamp pearl can not produce relatively mounting hole 101 and rock, thereby improves the reliable and stable nature of whole face guard 10 installations. Moreover, the raised heads 300 are staggered in the same row of mounting holes 101, so that the raised heads 300 form extrusion force on the lamp beads from the upper direction and the lower direction, on one hand, the stress of the whole light-emitting assembly and the mask 10 can be basically balanced, on the other hand, the mask 10 is prevented from being warped due to unbalanced stress in the mounting process, the mounting precision and the mounting efficiency of the mask 10 can be further improved, the damage to the lamp beads in the process of repeatedly debugging the mounting position of the mask 10 can be avoided, and the assembling safety of the display screen 20 is improved.
In some embodiments, the mask 10 may be made of metal or non-metal materials, and the entire mask 10 may be integrally formed, for example, by an injection molding process or a punch molding process. When the injection molding process is adopted for integral molding, the molten injection can be input into an injection mold by adopting a plunger type injection machine or a screw type injection machine, in order to avoid deformation caused by rapid temperature rise in the injection mold, a certain preheating treatment can be carried out on the whole injection mold before the injection mold is placed into a cavity of the injection mold, and the temperature of the preheating treatment can be 200-300 ℃. For example, the injection mold is placed on a worktable of the preheating device, the worktable gradually transfers heat to the injection mold to realize preheating, and the final preheating temperature of the two can be accurately displayed through the temperature sensor and the display screen 20.
After the injection mold is preheated, the molten injection liquid is injected into the injection mold at a certain pressure and speed, and after the injection of the molten injection liquid is completed, the injection machine is kept at a pressure for a set time (for example, about five seconds). After the melted injection liquid is partially solidified into the face mask 10 and contracted, the melted injection liquid continues to fill the contraction space under the action of the pressure of the injection machine, so that a large number of dents are prevented from appearing on the face mask 10. After the injection machine is kept at the pressure for a set time, the pressure of the injection machine is gradually reduced, so that the situation that the mask 10 generates burrs due to the overflow of the molten injection due to overhigh pressure or overlong pressure keeping time can be avoided.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
