Description

Technical Field

[0001] This application relates to the technical field of display devices, and in particular to a light-emitting element, a display unit, and a display device. Background Technology

[0002] Raster screens have become increasingly popular as outdoor display devices in recent years. Through their strip-shaped and perforated structure, they create unique visual effects. They not only inherit the brightness and clarity advantages of traditional LED displays but also achieve a perfect blend of transparency and aesthetics through their ingenious perforation design. Typically, raster screens use multiple LED strips arranged side-by-side at intervals as light-emitting devices. Each strip has multiple pixels spaced apart, and these pixels generally use RGB LEDs.

[0003] However, when the spacing between the light strips needs to be large, the brightness of a single pixel cannot be made very high due to space and physical limitations, causing the light strips to fail to meet the brightness requirements of some usage scenarios. In addition, when viewing the screen from above or below, there will be a color distortion, affecting the display effect and viewing experience. Utility Model Content

[0004] Therefore, it is necessary to provide a light-emitting element, display unit, and display device to address the problem that traditional technologies cannot meet the brightness requirements of some usage scenarios, thus affecting the display effect and viewing experience.

[0005] A first aspect of this application provides a light-emitting element, comprising:

[0006] The light panel, in its installed state, is defined with the direction from top to bottom as the first direction, the direction from bottom to top as the second direction, and the direction from left to right or right to left as the third direction; and

[0007] A first light-emitting unit and a second light-emitting unit are sequentially arranged on the lamp panel along the third direction. Each of the first and second light-emitting units includes a first LED, a second LED, and a third LED. The first, second, and third LEDs of the first light-emitting unit are sequentially arranged along the first direction, and the first, second, and third LEDs of the second light-emitting unit are sequentially arranged along the second direction. The first, second, and third LEDs emit different colors.

[0008] The light-emitting components in this solution are applied to the display unit of a display device. More specifically, multiple light-emitting components are arranged side by side to form a display unit. In use, the display unit is vertically installed and fixed by wall mounting or bracket support. At this time, the lamp board is also in a vertical installation posture. The direction from top to bottom of the lamp board is defined as the first direction, the direction from bottom to top is defined as the second direction, and the direction from left to right or from right to left is defined as the third direction. By installing the first light-emitting unit and the second light-emitting unit along the third direction on the lamp board, the two light-emitting units constitute a pixel. Since both the first light-emitting unit and the second light-emitting unit include a first LED, a second LED, and a third LED, the number of LEDs in the pixel of this solution is significantly increased compared to the traditional pixel which is composed of a single three-color LED. This increases the brightness of a single pixel, thus enabling the light-emitting component to obtain higher brightness capabilities, making it suitable for certain high-brightness application scenarios.

[0009] Furthermore, by arranging the first, second, and third LEDs of the first light-emitting unit sequentially along a first direction, and simultaneously arranging the first, second, and third LEDs of the second light-emitting unit sequentially along a second direction, on the one hand, the first and third LEDs can be seen simultaneously whether the light-emitting element is viewed from above or below, and the observed mixed light color is the same. Therefore, there is no visual color distortion, ensuring the display effect of the display device and the user's viewing experience. On the other hand, due to the 180° rotation of the LEDs in the first light-emitting unit and the second light-emitting unit, This allows the display unit to be installed either upright or upside down (without changing the arrangement of the LEDs in the first and second light-emitting units), making it more flexible and accommodating the need for two display units to share a single control box (the connection terminals of the display units are usually located at one end, so after rotating 180°, the connection terminals of the two display units face each other, allowing the control box to be easily connected to the connection terminals of both display units simultaneously). This also allows a single control box to connect to more display units, improving the utilization rate of the control box, reducing the number of control boxes required, and thus reducing costs.

[0010] The technical solution of this application will be further described below:

[0011] In one embodiment, the first LED is a red LED, the second LED is a green LED, and the third LED is a blue LED;

[0013] In one embodiment, the red LED of the first light-emitting unit and the blue LED of the second light-emitting unit are aligned or misaligned along the third direction.

[0014] In one embodiment, the green LED of the first light-emitting unit and the green LED of the second light-emitting unit are aligned or staggered along the third direction.

[0017] Alternatively, at least two of the red, green, and blue LEDs in the first light-emitting unit are offset along the first direction.

[0018] In one embodiment, the red, green, and blue LEDs of the second light-emitting unit are aligned along the second direction;

[0019] Alternatively, at least two of the red, green, and blue LEDs in the second light-emitting unit are offset along the second direction.

[0020] In one embodiment, the lamp board has mounting holes, and the first lamp bead, the second lamp bead, and the third lamp bead are all provided with solder feet. The solder feet are inserted into the mounting holes and welded to the lamp board for fixation.

[0021] Alternatively, the first light-emitting unit and the second light-emitting unit may be mounted on the lamp board using a surface mounting process.

[0022] In one embodiment, at least two of the first light-emitting unit and the second light-emitting unit are provided, and the first light-emitting unit and the second light-emitting unit are arranged alternately along the third direction.

[0023] In one embodiment, the colors of the first, second, and third LEDs of the first light-emitting unit are alternately arranged with the colors of the first, second, and third LEDs of the second light-emitting unit along the third direction.

[0024] A second aspect of this application also provides a display unit comprising:

[0025] Mounting rack; and

[0026] Multiple light-emitting elements as described in any of the above embodiments are arranged side-by-side at intervals on the mounting frame.

[0041] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0042] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0043] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0044] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0045] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0046] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0047] Typically, raster screens use multiple LED strips arranged side-by-side as light-emitting elements 11, with multiple pixels spaced apart on each strip. These pixels are generally in the form of RGB LEDs. However, when the spacing between the LED strips needs to be large, the brightness of individual pixels cannot be made very high due to space and physical limitations. This results in the LED strips failing to meet the brightness requirements of some usage scenarios. In addition, when viewing the screen from above or below, there may be a color distortion, affecting the display effect and viewing experience.

[0048] To address the aforementioned issues, this application employs two light-emitting units for each pixel on the light board 111, and arranges the tri-color LEDs of the two light-emitting units in a 180° rotation arrangement. This increases the number of LEDs per pixel, enhancing brightness and making it suitable for applications requiring high brightness. Furthermore, the LEDs at the top and bottom of each pixel are arranged in a consistent manner, ensuring a uniform light color effect regardless of whether the view is from above or below, thus avoiding color distortion issues.

[0049] See Figure 1 and Figure 2 One embodiment of this application provides a display device 100, which includes at least one control box 20 and at least two display units 10. The two display units 10 are assembled by end splicing, and the control box 20 is installed at the splicing point of the two display units 10 and is electrically connected to both display units 10.

[0050] For example, the display unit 10 has a rectangular structure. When splicing, one display unit 10 is assembled by connecting one end of its length or width direction to the other end of its length or width direction. The splicing method can be at least one of screw connection, snap connection, magnetic connection, etc., and can be flexibly selected according to actual needs.

[0051] It should be noted that when a larger display area is required, one control box 20 and two display units 10 constitute a display screen. Multiple display screens can then be assembled in an array structure to obtain a larger total display area. For example, Figure 1 The display device 100 shown is composed of two displays assembled together.

[0052] To facilitate the installation and fixing of each display screen, the display device 100 is also equipped with a mounting bracket or a wall mount mechanism. The mounting bracket is used to enable the display device 100 to be installed on the floor, and the wall mount mechanism is used to enable the display device 100 to be wall mounted.

[0053] Please continue reading. Figure 2 In one embodiment of this application, the display unit 10 includes a mounting frame 30 and a plurality of light-emitting elements 11, which are arranged side-by-side at intervals on the mounting frame 30. The mounting frame 30 is used to mount and fix the light-emitting elements 11 and the control box 20.

[0054] For example, the light-emitting element 11 can be, but is not limited to, a light strip.

[0055] In this application, the mounting bracket 30 can have various structural designs. For example, when the mounting bracket 30 is rectangular, multiple light strips can be installed side by side with intervals along the length of the mounting bracket 30, or they can be installed side by side with intervals along the width of the mounting bracket 30, which can be flexibly selected as needed.

[0056] Please continue reading. Figure 4 In one embodiment of this application, the light-emitting element 11 includes a lamp board 111, a first light-emitting unit 112, and a second light-emitting unit 113. For example, the lamp board 111 may be a circuit board, used to mount and integrate the first light-emitting unit 112 and the second light-emitting unit 113, and the lamp board 111 is electrically connected to the first light-emitting unit 112 and the second light-emitting unit 113.

[0057] The direction from top to bottom of the lamp panel 111 in the installation state is defined as the first direction, the direction from bottom to top of the lamp panel 111 is defined as the second direction, and the direction from left to right or from right to left of the lamp panel 111 is defined as the third direction.

[0058] Specifically, the first direction specifically refers to Figure 4 The direction pointed to by arrow S1 in the image, specifically refers to the second direction. Figure 4 The arrow S2 in the image points to a specific third direction. Figure 4 The direction of arrow S3 in the diagram.

[0059] It should be noted that the lamp panel 111 in the installed state is either in a vertical position or slightly tilted at a small angle (e.g., 5°~10°).

[0060] When the light panel 111 is rectangular, in the installed state, the length direction of the light panel 111 is located in the vertical direction, which corresponds to the up and down direction mentioned above; the width direction is located in the horizontal direction, which corresponds to the left and right direction mentioned above.

[0061] Please continue reading. Figure 4 The first light-emitting unit 112 and the second light-emitting unit 113 are sequentially disposed on the lamp panel 111 along a third direction S3. Both the first light-emitting unit 112 and the second light-emitting unit 113 include a first LED 114, a second LED 115, and a third LED 116. The first LED 114, the second LED 115, and the third LED 116 of the first light-emitting unit 112 are sequentially disposed along a first direction S1, and the first LED 114, the second LED 115, and the third LED 116 of the second light-emitting unit 113 are sequentially disposed along a second direction S2. The first LED 114, the second LED 115, and the third LED 116 emit different colors.

[0062] It is easy to understand that when the light-emitting element 11 is observed from the left or right, the first LED 114, the second LED 115 and the third LED 116 can be observed at the same time. Therefore, there will be no color distortion problem when viewed from the left or right.

[0063] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: The light-emitting element 11 of this solution is applied to the display unit 10 of the display device 100. More specifically, multiple light-emitting elements 11 are arranged side by side to form the display unit 10. In use, the display unit 10 is vertically installed and fixed by wall mounting or bracket support. At this time, the lamp panel 111 is also in a vertical installation posture. At this time, the direction of the lamp panel 111 from top to bottom is defined as the first direction S1, the direction from bottom to top is defined as the second direction S2, and the direction from left to right or from right to left is defined as the third direction S3. 3; By installing the first light-emitting unit 112 and the second light-emitting unit 113 on the lamp board 111 along the third direction S3, the two light-emitting units constitute a pixel. Since the first light-emitting unit 112 and the second light-emitting unit 113 both include the first LED 114, the second LED 115 and the third LED 116, the number of LEDs in the pixel of this solution is significantly increased compared with the traditional pixel which is composed of a single three-color LED. This can enhance the brightness of a single pixel, and also enable the light-emitting component 11 to obtain higher brightness capability, which can be applied to some high-brightness application scenarios.

[0064] It should be noted that, in order to obtain a larger light-emitting area and higher light-emitting brightness, each light-emitting element 11 is provided with multiple pixels arranged in close proximity. Each pixel is composed of a first light-emitting unit 112 and a second light-emitting unit 113. At this time, each pixel is a light-emitting point, and multiple pixels emit light simultaneously to form the surface-emitting effect required by the display unit 10.

[0065] Please continue reading. Figure 3 and Figure 4Furthermore, by sequentially arranging the first LED 114, second LED 115, and third LED 116 of the first light-emitting unit 112 along the first direction S1, and simultaneously arranging the first LED 114, second LED 115, and third LED 116 of the second light-emitting unit 113 along the second direction S2, on the one hand, regardless of whether the light-emitting element 11 is viewed from above or below, the first LED 114 and third LED 116 can be seen simultaneously, and the observed mixed light color is the same. Therefore, there is no visual distortion due to viewing angle, ensuring the display effect of the display device 100 and the user's viewing experience. On the other hand, because the LEDs of the first light-emitting unit 112 and the second light-emitting unit 113 are rotated 180°, The structural layout allows the display unit 10 to be installed either upright or upside down (in which case the arrangement of the LEDs in the first light-emitting unit 112 and the second light-emitting unit 113 in space will not be changed), making it more flexible to use. It can also meet the need for two display units 10 to share a single control box 20 at the same time (the connection terminals 12 of the display unit 10 are usually located at one end, so after rotating 180°, the connection terminals 12 of the two display units 10 face each other, making it easy for the control box 20 to connect to the connection terminals 12 of the two display units 10 at the same time). This allows a single control box 20 to connect more display units 10, improving the utilization rate of the control box 20, reducing the number of control boxes 20 used, and thus reducing costs.

[0066] Please continue reading. Figure 4 Based on the above embodiments, in one embodiment, the first LED 114 is a red LED 114a, the second LED 115 is a green LED 115a, and the third LED 116 is a blue LED 116a. It can also be understood that the first light-emitting unit 112 and the second light-emitting unit 113 are both RGB LEDs (R corresponds to Red, G corresponds to Green, and B corresponds to Blue), and a full-color display effect can be achieved by mixing these three primary colors.

[0067] The red LED 114a of the first light-emitting unit 112 and the blue LED 116a of the second light-emitting unit 113 are arranged at intervals along the third direction S3. The green LED 115a of the first light-emitting unit 112 and the green LED 115a of the second light-emitting unit 113 are arranged at intervals along the third direction S3. The blue LED 116a of the first light-emitting unit 112 and the red LED 114a of the second light-emitting unit 113 are arranged at intervals along the third direction S3.

[0068] Therefore, when using the light-emitting element 11, whether the user observes it from above or below, they can simultaneously see the mixed light emitted by the red LED 114a and the blue LED 116a, thus avoiding any visual distortion and ensuring a good visual experience. The LEDs arranged along the third direction S3 are spaced apart to avoid them being too close together and blocking each other's light, and also to prevent installation interference. Furthermore, this arrangement allows for sufficient heat dissipation between adjacent LEDs, ensuring effective heat dissipation.

[0069] like Figure 7 As shown and combined Figure 4 Furthermore, in yet another embodiment, the red LED 114a of the first light-emitting unit 112 and the blue LED 116a of the second light-emitting unit 113 are aligned or staggered along a third direction S3. The green LED 115a of the first light-emitting unit 112 and the green LED 115a of the second light-emitting unit 113 are aligned or staggered along a third direction S3. The blue LED 116a of the first light-emitting unit 112 and the red LED 114a of the second light-emitting unit 113 are aligned or staggered along a third direction S3.

[0070] For example, the accompanying drawings of this application show an embodiment in which the red LED 114a of the first light-emitting unit 112 and the blue LED 116a of the second light-emitting unit 113 are aligned along a third direction S3, the green LED 115a of the first light-emitting unit 112 and the green LED 115a of the second light-emitting unit 113 are aligned along a third direction S3, and the blue LED 116a of the first light-emitting unit 112 and the red LED 114a of the second light-emitting unit 113 are aligned along a third direction S3. The alignment arrangement can reduce the installation difficulty of each LED and make the arrangement of each LED more regular and orderly, so that the light emitted by each LED can be more effectively converged to obtain a better light effect.

[0071] By staggering the pairs of LEDs arranged along the third direction S3, it is possible to avoid mutual obstruction between the LEDs when viewed from the left or right, thus achieving a better light-emitting effect.

[0072] Please continue reading. Figures 5 to 7 Furthermore, in another embodiment, the red LED 114a, green LED 115a, and blue LED 116a of the first light-emitting unit 112 are aligned along the first direction S1, or at least two of the red LED 114a, green LED 115a, and blue LED 116a are misaligned along the first direction S1.

[0073] Similarly, the red LED 114a, green LED 115a, and blue LED 116a of the second light-emitting unit 113 are aligned along the second direction S2, or at least two of the red LED 114a, green LED 115a, and blue LED 116a are misaligned along the second direction S2.

[0074] For example, taking the first light-emitting unit 112 as an example, the red LED 114a may be offset a certain distance away from or closer to the second light-emitting unit 113, so that the red LED 114a and the aligned green LED 115a and blue LED 116a are misaligned along the first direction S1.

[0075] Alternatively, the red LED 114a and the green LED 115a can be simultaneously offset a certain distance away from or towards the second light-emitting unit 113, aligning the red LED 114a and the green LED 115a, and both being offset from the blue LED 116a along the first direction S1; or, one of the red LED 114a and the green LED 115a can be offset a certain distance towards the second light-emitting unit 113, while the other is offset a certain distance away from the second light-emitting unit 113, so that the red LED 114a, green LED 115a, and blue LED 116a are all offset along the first direction S1, and so on. This allows for different LED layout schemes and enables different product designs.

[0076] The staggered arrangement of each LED in the second light-emitting unit 113 can be set with reference to the first light-emitting unit 112. The staggered arrangement of each LED in the second light-emitting unit 113 and the first light-emitting unit 112 can be the same or different. The choice can be made flexibly according to actual needs, and will not be elaborated here.

[0077] In actual production, there are various ways to install the first light-emitting unit 112 and the second light-emitting unit 113 on the lamp board 111. For example, in one embodiment, the lamp board 111 has mounting holes, and the first lamp bead 114, the second lamp bead 115, and the third lamp bead 116 are all provided with solder feet. The solder feet are inserted into the mounting holes and welded to the lamp board 111. Inserting the solder feet into the mounting holes can achieve pre-positioning of the installation. On this basis, welding is then performed to reliably fix the first lamp bead 114, the second lamp bead 115, and the third lamp bead 116 on the lamp board 111, resulting in high connection strength and good stability. At this time, the solder feet contact the conductive structure (such as embedded wires, copper plating, etc.) on the inner side of the lamp board 111 to achieve electrical connection between the first lamp bead 114, the second lamp bead 115, and the third lamp bead 116 and the lamp board 111.

[0078] At this point, it can be understood that the first light-emitting unit 112 and the second light-emitting unit 113 are DIP (Dual In-line Package) LEDs.

[0079] Alternatively, in another embodiment, the first light-emitting unit 112 and the second light-emitting unit 113 are mounted on the lamp board 111 using a surface mount technology. Specifically, the first light-emitting unit 112 and the second light-emitting unit 113 can be mounted on the lamp board 111 using, but not limited to, SMT (Surface Mount Device) technology, which provides high connection reliability and good installation stability, helping to ensure that the first light-emitting unit 112 and the second light-emitting unit 113 obtain better light-emitting characteristics.

[0080] At this point, it can be understood that the first light-emitting unit 112 and the second light-emitting unit 113 are SMT LED beads.

[0081] Furthermore, based on any of the above embodiments, at least two of the first light-emitting unit 112 and the second light-emitting unit 113 are provided, and the first light-emitting unit 112 and the second light-emitting unit 113 are arranged alternately along the third direction S3. In this way, by configuring a larger number of first light-emitting units 112 and second light-emitting units 113 on a single pixel, the number of LED beads can be further increased to obtain higher luminous brightness, making the light-emitting element 11 suitable for use in higher brightness scenarios; in addition, by adopting the alternating arrangement of the first light-emitting unit 112 and the second light-emitting unit 113, it can also be ensured that when viewing the light-emitting element 11 from above or below, there are always the same number and type of LED beads in the field of view, thereby avoiding the problem of color distortion from the viewing angle.

[0082] For example, in one embodiment, the first light-emitting unit 112 and the second light-emitting unit 113 can be arranged in an alternating manner along the third direction S3.

[0083] Alternatively, in other optional embodiments, there may be a configuration of two first light-emitting units 112 and one second light-emitting unit 113. In this case, the second light-emitting unit 113 is located between the two first light-emitting units 112 and forms a pixel. At this time, the pixel is arranged with two red LEDs 114a and one blue LED 116a above it, and the pixel is also arranged with two red LEDs 114a and one blue LED 116a below it.

[0084] Alternatively, it can be configured with two first light-emitting units 112 and two second light-emitting units 113. In this case, the first light-emitting units 112 and the second light-emitting units 113 are alternately arranged to form a pixel. At this time, the top of the pixel is a combination of two red LEDs 114a and two blue LEDs 116a, and the bottom of the pixel is also a combination of two red LEDs 114a and two blue LEDs 116a, etc. The specific configuration can be flexibly selected according to actual needs.

[0085] In another embodiment, the colors of the first LED 114, second LED 115, and third LED 116 of the first light-emitting unit 112 are staggered with the colors of the first LED 114, second LED 115, and third LED 116 of the second light-emitting unit 113 along a third direction S3. For example, the first light-emitting unit 112 uses red LED 114a, green LED 115a, and blue LED 116a arranged along a first direction, while the second light-emitting unit 113 uses green LED 115a, red LED 114a, and blue LED 116a arranged along a second direction, and are staggered one-to-one with the red LED 114a, green LED 115a, and blue LED 116a of the first light-emitting unit 112 along a third direction S3. In this case, when an observer views the display device 100 from the left and right sides at an oblique angle, the same mixed light color display effect can be observed from both sides, avoiding the problem of color distortion from the viewing angle.

[0086] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0087] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
