Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a mask and a display unit. Background Art

[0002] LED display is a kind of display composed of LED display modules. Compared with other flat panel displays, it has high brightness and high contrast, displays colors closest to the real colors of nature, has a long service life, low power consumption, and can be assembled infinitely in units of cabinets, breaking through the size limit. It has been widely used in conference forums, commercial media, industry command centers, sports stadiums, securities trading and other fields, and has begun to be used in virtual shooting and high-end cinema screens.

[0003] In recent years, as the dot pitch of LED display modules has become smaller and smaller, the image fineness and grayscale have become higher and higher. The modules have developed from SMD and mask technology to small pitch below P2.5 and Mini LED and Micro LED modules below P1.0 using COB (chip-on-board) packaging. As COB process technology becomes more and more perfect, large-pitch outdoor fixed installation, rental and other markets have also become a trend. However, the current COB supply chain materials can only meet indoor requirements and cannot meet the use in outdoor environments.

[0004] With the popularization of LED application products, LED outdoor display products are being used more and more widely, and the corresponding demand for pixel pitch of outdoor LED screens is getting smaller and smaller. Due to the constraints of materials, processing technology and other reasons, the design and production path of traditional outdoor display screens cannot achieve products with specifications below P2.5 pitch. In recent years, the application and development of COB process technology and materials have made it possible to apply COB process in outdoor scenes. The use of COB process for outdoor products with pixel pitch below P2.5 has become a future trend.

[0005] However, in traditional display screens, the protection and display effects of LED lamp beads are relatively poor.

[0006] BACKGROUND OF THE PRESENT APPLICATION The above information disclosed is only used to understand the background of the concept of the present application, and does not indicate or imply that it contains information of the prior art. Utility Model Content

[0007] Based on this, it is necessary to provide a mask and a display unit to address the above problems.

[0008] A face mask comprising:

[0009] A cover body, the cover body having a first surface and a second surface disposed opposite to each other, and a lamp hole is provided on the first surface; and

[0010] A brim is protruding from the first surface and is located above the lamp hole in the first direction of the cover body, the brim is bent toward the lamp hole to form a receiving groove, the receiving groove is used to accommodate at least part of the lamp bead, and the projection of the brim on the mask at least partially falls into the lamp hole.

[0011] Before describing the technical effects that can be achieved by the embodiments of the present application, it should be noted that in the traditional mask design, such as the attached embodiment of the present application, Figure 5 As shown in the figure, the LED lamp beads are located in the middle of the upper and lower brims, so the LED lamp beads are exposed to sunlight for a long time, which aggravates the heat radiation and aging of the LED lamp beads. The luminous surface of the LED lamp beads is directly exposed to sunlight, which requires a higher luminous brightness for better display effects, resulting in reduced contrast, shorter life and other performance degradation problems; at the same time, it also causes the LED display screen to not present the maximum downward viewing angle, reducing the visible range of the LED display screen. In traditional masks, the LED lamp beads are located in the middle of the upper and lower brims, which does not provide good protection for the LED display screen and does not optimize the display effect.

[0012] In the face of the above-mentioned problems, the above-mentioned mask of the present application can at least achieve the following beneficial effects: the present application changes the relative position of the lamp beads and the brim of the mask in the traditional design, moves the lamp beads upward relative to the mask, and hides the lamp beads in the accommodating groove under the brim of the mask, thereby reducing the exposure time of sunlight by blocking the sunlight by the brim, weakening the heat radiation of sunlight to the lamp beads, delaying the aging of the lamp beads, improving the contrast of the display unit, and optimizing the performance of the display unit, thereby achieving the purpose of protecting the lamp beads and optimizing the display effect.

[0013] In one embodiment, the brim includes a first brim body and a second brim body, the first brim body is connected to the first surface, the other end of the first brim body is connected to the second brim body, the second brim body is arranged at an angle to the first brim body, and the second brim body is spaced apart from the first surface to enclose the accommodating groove.

[0014] In one embodiment, the width of the receiving groove is equal to the width of the lamp hole. The width of the receiving groove is equal to the width of the lamp hole, which is convenient for component molding and processing.

[0015] In one embodiment, the first eaves body is perpendicular to the second eaves body.

[0016] In one of the embodiments, on the longitudinal cross-sectional profile of the cover body, the brim, the lamp hole and the lamp bead are all arranged in plurality, the lamp bead corresponds to the lamp hole one by one, the brim corresponds to the lamp hole one by one, and the plurality of lamp holes are arranged at equal intervals along the first direction of the cover body; in the first direction of the cover body, the line connecting the center of any lamp hole and the end of the brim above it and the second direction form a first angle; the line connecting the center of any lamp hole and the end of the brim below it and the second direction form a second angle, and the first angle is smaller than the second angle. It can be understood that under normal circumstances, the display unit is usually hung at a high position, such as on the relatively high outer side of a building, and its audience is at the bottom of the display unit, that is, the audience is at an upward viewing angle, and therefore pays more attention to the downward viewing angle. A larger downward viewing angle represents a larger audience range for screen playback. In this embodiment, the first angle can be considered as the upper viewing angle, and the second angle can be considered as the lower viewing angle. The first angle is smaller than the second angle, that is, the upper viewing angle is smaller than the lower viewing angle. The lower viewing angle of the display unit is larger, which can increase the visible range of the screen and bring better viewing effects to people who are at a relatively low place and looking up at the display unit.

[0017] In one embodiment, the mask further includes a light-blocking portion, which is protruding from the first surface. In the first direction of the longitudinal cross-sectional profile of the mask body, at least one light-blocking portion is provided between any of the brim and the lamp hole above it.

[0018] In one embodiment, the number of the brims is set to be multiple, the multiple brims are arranged along the second direction, and a groove is provided between any two adjacent brims, and the width of the groove is 0.1mm-1.5mm. The groove can improve the flexibility of the mask, but if the groove width is too large, too much sunlight will pass through, and the sunlight will reflect on the mask and reduce the contrast. It is necessary to limit the groove width to 0.1mm-1.5mm, which not only improves the flexibility of the mask, but also makes the display unit have a higher contrast.

[0019] In one embodiment, the end of the light shielding portion does not exceed the line connecting the center of any of the lamp holes and the end of the brim below it. Such a setting means that the light shielding portion does not affect the transmission of the light emitted by the lamp beads in the lower viewing angle range, does not reduce the lower viewing angle, and the shielding portion can also evenly disperse the light under each lamp bead, avoiding the uneven brightness caused by excessive light gathering under the lamp bead.

[0020] In one embodiment, a plurality of grooves are provided on the light shielding portion. The specific shape and size of the grooves are not limited. The grooves provided on the light shielding portion can also save materials, reduce manufacturing costs, and reduce the overall weight of the mask.

[0021] In one embodiment, the projection of the brim on the mask does not pass over the center of the lamp bead. Such a setting can prevent the brim from over-shielding the light-emitting surface of the lamp bead, resulting in a small downward viewing angle, and ensure that the light emitted from the center of the lamp bead still has a certain angle of upward viewing angle, avoiding all-downward light emission, and controlling light pollution while ensuring the light emission effect.

[0022] In one embodiment, the ratio of the distance between the end of the brim and the center of the lamp hole to the distance between the centers of two adjacent lamp holes is 1 / 10 to 1 / 5. If the brim is bent too much, that is, too close to the center of the lamp hole, it will block too many light-emitting surfaces of the lamp beads. If the viewer is far away from the screen, even if the screen height is relatively high, the viewing angle will be close to the horizontal view, and the light will be blocked, resulting in insufficient brightness; in addition, when viewed from the side, the left and right viewing angles will also be partially blocked, resulting in poor display effects; limiting the ratio of 1 / 10-1 / 5 can make the display effect more balanced and not block too much.

[0023] In one embodiment, the cover body and the brim are integrally formed. Such a configuration can improve production efficiency, and the cover body and the brim can be integrally formed by a mold, which can be preferably made of an opaque material such as plastic or metal.

[0024] The present application also provides a display unit, which includes a mask as described in any of the above embodiments. The above display unit may be provided with the mask described in each of the above embodiments, and therefore, the display unit also includes at least the following beneficial effects: the relative position of the lamp beads and the brim of the mask in the traditional design is changed, the lamp beads are moved upward relative to the mask, and the lamp beads are hidden in the receiving groove under the brim of the mask, and the time of sunlight exposure is reduced by blocking the sunlight by the brim, reducing the heat radiation of sunlight to the lamp beads, delaying the aging of the lamp beads, improving the contrast of the display unit, and optimizing the performance of the display unit, thereby achieving the effect of protecting the lamp beads and optimizing the display effect.

[0025] In one embodiment, the display unit also includes a bottom shell and a light board, the light board is arranged in the bottom shell, the cover body is covered to the bottom shell with the second surface facing the bottom shell, the lamp hole passes through the cover body and the two ends of the lamp hole are the first surface and the second surface respectively, and a lamp bead is arranged on the light board, and one end of the lamp bead is passed through the lamp hole to be electrically connected to the light board.

[0034] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0035] See also Figure 1 , Figure 2 , Figure 3 and Figure 4In some embodiments, the present application provides a mask 11, which includes a mask body 100 and a brim 200. The mask body 100 has a first surface and a second surface disposed opposite to each other along a thickness direction T, and a lamp hole 110 is provided on the first surface; the brim 200 is convexly disposed on the first surface and is located above the lamp hole 110 in a first direction H (which can be considered as a height direction) of the mask body 100, and the brim 200 is bent toward a direction close to the lamp hole 110 to form a receiving groove 230, and the receiving groove 230 is used to accommodate at least part of the lamp bead 300, and the projection of the brim 200 on the mask 11 at least partially falls into the lamp hole 110.

[0036] Before describing the technical effects that can be achieved by the embodiments of the present application, it should be noted that in the conventional design of the mask 11, as shown in the attached drawings of the present application, Figure 5 As shown, the LED lamp bead 300 is located in the middle of the upper and lower brims 200, so the LED lamp bead 300 is exposed to sunlight for a long time, which aggravates the heat radiation and aging of the LED lamp bead 300 by sunlight. The light-emitting surface of the LED lamp bead 300 is directly exposed to sunlight, which requires a higher light brightness for better display effect, resulting in performance degradation problems such as reduced contrast and shortened life; at the same time, it also causes the LED display screen 10 to not present the maximum downward viewing angle, reducing the visible range of the LED display screen 10. In the traditional mask 11, the LED lamp bead 300 is located in the middle of the upper and lower brims 200, which does not provide good protection for the LED display screen 10 and does not optimize the display effect.

[0037] In the face of the above-mentioned problems, the above-mentioned mask 11 of the present application can at least achieve the following beneficial effects: the present application changes the relative position of the lamp bead 300 and the brim 200 of the mask 11 in the traditional design, moves the lamp bead 300 upward relative to the mask 11, and hides the lamp bead 300 in the accommodating groove 230 under the brim 200 of the mask 11, and reduces the exposure time of sunlight by blocking the sunlight by the brim 200, weakens the heat radiation of sunlight to the lamp bead 300, delays the aging of the lamp bead 300, improves the contrast of the display unit 10, and optimizes the performance of the display unit 10, thereby achieving the purpose of protecting the lamp bead 300 and optimizing the display effect.

[0038] Specifically, Figure 4As shown, in some embodiments, on the longitudinal cross-sectional profile of the cover body 100, the brim 200, the lamp hole 110 and the lamp bead 300 are all arranged in plurality, the lamp bead 300 corresponds to the lamp hole 110 one-to-one, the brim 200 corresponds to the lamp hole 110 one-to-one, and the plurality of lamp holes 110 are arranged at equal intervals along the first direction H of the cover body 100; on the first direction H of the cover body 100, the center of the surface of any lamp bead 300 and the line connecting the end of the brim 200 above it are arranged at a first angle with the second direction; the center of the surface of any lamp bead 300 and the line connecting the end of the brim 200 below it are arranged at a second angle with the second direction, and the first angle is smaller than the second angle. For example, as Figure 4 As shown, in the first direction H of the longitudinal cross-sectional profile of the cover body 100, the minimum distance between the end of the brim 200 and the surface of the lamp bead 300 is h, that is, the height of the brim 200 is h, the minimum distance between the end of the brim 200 and the center line of the lamp bead 300 below it is d1, and the minimum distance between the end of the brim 200 and the center line of the lamp bead 300 above it is s1; and as Figure 5 As shown, in the conventional display unit 10, in the first direction H of the longitudinal cross-sectional profile of the cover body 100, the minimum distance between the end of the upper brim 200 and the surface of the lamp bead 300 below it is h, the minimum distance between the end of the lower brim 200 and the center line of the lamp bead 300 above it is d2, and the minimum distance between the end of the brim 200 and the center line of the lamp bead 300 above it is s2. Figure 4 and Figure 5 It can be seen that the mask 11 of the present application and the traditional mask 11, both of which have the same pixel pitch P (P=d1+s1=d2+s2), the same brim 200 height h, the angle of sunlight irradiation and the comparison of the lower viewing angle:

[0039]

[0040]

[0041] It can be understood that the display unit 10 is usually hung at a high position under normal circumstances, such as on the relatively high outer surface of a building, and its audience is at the lower part of the display unit 10, that is, the audience is at an upward angle, and therefore pays more attention to the lower viewing angle. A larger lower viewing angle represents a larger screen playback audience range. In this embodiment, the first angle can be considered as the angle of the upper viewing angle, and the second angle can be considered as the angle of the lower viewing angle. The first angle is smaller than the second angle, that is, the upper viewing angle is smaller than the lower viewing angle. The lower viewing angle of the display unit 10 is larger, which can increase the visible range of the screen, and bring better viewing effects to people who are at a relatively low position and look up at the display unit 10.

[0042] Specifically, Figure 4As shown, in some embodiments, the projection of the brim 200 on the mask 11 does not cross the center of the lamp bead 300. Such a setting can prevent the brim 200 from overly covering the light-emitting surface of the lamp bead 300, resulting in a small downward viewing angle, and make the light emitted from the center of the lamp bead 300 still have a certain angle of upward viewing angle, avoiding all downward light emission, and controlling light pollution while ensuring the light emission effect.

[0043] See also Figure 4 In some embodiments, the hat brim 200 includes a first brim body 210 and a second brim body 220, the first brim body 210 is connected to the first surface, the other end of the first brim body 210 is connected to the second brim body 220, the second brim body 220 is arranged at an angle to the first brim body 210, and the second brim body 220 is spaced apart from the first surface to enclose the accommodating groove 230.

[0044] Specifically, in some embodiments, the first eaves body 210 is perpendicular to the second eaves body 220 .

[0045] Specifically, in some embodiments, the cover body 100 and the brim 200 are integrally formed. Such a configuration can improve production efficiency, and the cover body 100 and the brim 200 can be integrally formed by a mold, which can be preferably made of opaque materials such as plastic and metal.

[0046] Specifically, Figure 3 As shown, in some embodiments, the width of the receiving groove 230 is equal to the width of the lamp hole 110. The width of the receiving groove 230 is equal to the width of the lamp hole 110, which facilitates component molding and processing.

[0047] Specifically, Figure 3 As shown, in some embodiments, the number of the brims 200 is set to be multiple, and the multiple brims 200 are arranged along the second direction S (which can be considered as the horizontal direction), and a groove 240 is provided between any two adjacent brims 200, and the width of the groove 240 is 0.1mm-1.5mm. The opening of the groove 240 can improve the flexibility of the mask 11, but if the width of the groove 240 is too large, too much sunlight will pass through, and the sunlight will reflect on the mask 11 and reduce the contrast. It is necessary to limit the width of the groove 240 to 0.1mm-1.5mm, which not only improves the flexibility of the mask 11, but also makes the display unit 10 have a higher contrast.

[0048] Specifically, Figure 4As shown, in some embodiments, the ratio of the distance between the end of the brim 200 and the center of the lamp hole 110 (i.e., d1) to the distance between the centers of two adjacent lamp holes 110 (i.e., P) is 1 / 10 to 1 / 5. If the brim 200 is bent too much, that is, too close to the center of the lamp hole 110, it will block too many light-emitting surfaces of the lamp beads 300. If the viewer is far away from the screen, even if the screen height is relatively high, the viewing angle will tend to be level, and the light will be blocked, resulting in insufficient brightness; in addition, when viewed from the side, the left and right viewing angles will also be partially blocked, resulting in poor display effects; limiting the ratio of 1 / 10-1 / 5 can make the display effect more balanced and not block too much.

[0049] See also Figure 4 In some embodiments, the mask 11 further includes a light blocking portion 400, which is protruding from the first surface. In the first direction H of the longitudinal cross-sectional profile of the mask body 100, at least one light blocking portion 400 is provided between any of the brim 200 and the lamp hole 110 above it.

[0050] Specifically, Figure 4 As shown, in some embodiments, the end of the light shielding portion 400 does not exceed the line connecting the center of the surface of any of the lamp beads 300 and the end of the brim 200 below it. Such a setting means that the light shielding portion 400 does not affect the transmission of the light emitted by the lamp beads 300 in the lower viewing angle range, does not reduce the lower viewing angle, and the shielding portion can also evenly disperse the light under each lamp bead 300, avoiding the uneven brightness caused by excessive light gathering under the lamp bead 300.

[0051] Specifically, Figure 4 As shown, in some embodiments, a plurality of grooves 410 are provided on the light shielding portion 400. The specific shape and size of the grooves 410 are not limited, and the grooves 410 provided on the light shielding portion 400 can also save materials, reduce manufacturing costs, and reduce the overall weight of the mask 11.

[0052] In addition, if Figure 4As shown, the present application also provides a display unit 10, which includes the mask 11 as described in any of the above embodiments. The above display unit 10 may be provided with the mask 11 described in each of the above embodiments, and therefore, the display unit 10 also includes at least the following beneficial effects: the relative position of the lamp bead 300 and the brim 200 of the mask 11 in the traditional design is changed, the lamp bead 300 is moved up relative to the mask 11, and the lamp bead 300 is hidden in the receiving groove 230 below the brim 200 of the mask 11, and the brim 200 of the mask 11 is shielded by the sun to reduce the exposure time of the sun, reduce the heat radiation of the sun to the lamp bead 300, delay the aging of the lamp bead 300, improve the contrast of the display unit 10, and optimize the performance of the display unit 10, thereby achieving the effect of protecting the lamp bead 300 and optimizing the display effect.

[0053] Specifically, Figure 4 As shown, in some embodiments, the display unit 10 also includes a bottom shell 12 and a light board 13, the light board 13 is arranged in the bottom shell 12, the cover body 100 covers the bottom shell 12 and the second surface faces the bottom shell 12, the lamp hole 110 passes through the cover body 100 and the two ends of the lamp hole 110 are the first surface and the second surface respectively, a lamp bead 300 is arranged on the light board 13, and one end of the lamp bead 300 is passed through the lamp hole 110 to be electrically connected to the light board 13.
