Description

Technical Field

[0001] The present application relates to the field of display technologies, and particularly to a display device. Background Art

[0002] In a direct - type backlight module, the diffusion plate is relatively thin and there is a large space between the diffusion plate and the backplane. To prevent the diffusion plate from sagging in the middle due to its own weight and affecting the image quality, a diffusion plate support frame is provided in the middle of the diffusion plate. The diffusion plate support frame is respectively connected to the diffusion plate and the backplane to prevent the deformation of the diffusion plate.

[0003] In related technologies, the diffusion plate support frame usually includes a support portion perpendicular to the diffusion plate. Both the diffusion plate and the diffusion plate support frame are made of rigid materials. And in order to reduce light shielding, thereby preventing uneven light distribution and then forming a support shadow on the diffusion plate and affecting the overall viewing effect, the cross - sectional area of the end of the support portion in contact with the diffusion plate in the length direction is designed to be as small as possible, resulting in a relatively large pressure at the position on the diffusion plate corresponding to the top end of the support portion. However, when the diffusion plate is pressed or dropped and impacted, the diffusion plate will squeeze the diffusion plate support frame. Since the pressure at the position on the diffusion plate corresponding to the top end of the support portion is relatively large, it is easy to cause defects such as deformation, bending or fracture of the diffusion plate, further exacerbating support shadows, blue spots on the display, and screen jumping defects.

[0030] To make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0031] A display device provided by an embodiment of the present application includes a display panel and a backlight module. The display panel is configured to display an image. The display panel itself does not emit light and needs to rely on the light source provided by the backlight module to achieve brightness display. In other words, the backlight module is used to provide a light source for the display panel. The display panel is located on the light-emitting side of the backlight module. The shape and size of the display panel generally match the shape and size of the backlight module respectively. Usually, the display panel can be set as a rectangle. The display panel is a transmissive display panel, which can modulate the light transmittance but does not emit light itself. The display panel has a plurality of pixel units arranged in an array. Each pixel unit can independently control the light transmittance and color of the light incident on the pixel unit from the backlight module, so that the light transmitted through all the pixel units forms the displayed image.

[0032] Among them, the display panel has an opposite display side and a light-incident side, and the backlight module is disposed on the light-incident side of the display panel. The display side refers to the side of the display panel for displaying the picture, and the light-incident side refers to the other side opposite to the display side.

[0033] It should be noted that the backlight module can directly emit white light, and the white light is emitted to the display panel after being subjected to light homogenization processing. Or, the backlight module can also emit other color lights, and then emit them to the display panel after color conversion and light homogenization processing. Specific selection can be made according to actual situations, and the present disclosure does not make specific limitations thereto. In addition, the backlight module is usually located at the bottom of the display device, and its shape and size are adapted to the shape and size of the display device. When applied to fields such as televisions or mobile terminals, the backlight module usually adopts a rectangular shape.

[0034] The backlight module in the embodiment of the present utility model adopts a direct-lit backlight module, which is used to uniformly emit light within the entire light-emitting surface, and provide light with sufficient brightness and uniform distribution for the display panel, so that the display panel can normally display images.

[0035] Refer to Figure 1 And Figure 2 , Figure 1 FIG. shows a structural diagram of the diffusion plate support frame 14 in the backlight module 10 of the display device according to an embodiment of the present application in an uncompressed state. Figure 2 FIG. shows a structural diagram of the diffusion plate support frame 14 in the backlight module 10 of the display device according to an embodiment of the present application in a compressed state. The backlight module 10 includes a back plate 11, a substrate 12, a diffusion plate 13, and a diffusion plate support frame 14.

[0036] The back plate 11 is located at the bottom of the backlight module 10 and has a supporting and carrying function. The back plate 11 is disposed on the light-incident side of the display panel. The back plate 11 is generally a square structure. Of course, when applied to a special-shaped display device, its shape is adapted to the shape of the display device.

[0037] The material of the back plate 11 includes but is not limited to aluminum, iron, aluminum alloy, or iron alloy, etc.

[0038] The back plate 11 is used to support the substrate 12, and support and fix the edge positions of components such as the diffusion plate 13 and optical films. The back plate 11 also plays a role in dissipating heat from the substrate 12.

[0039] In this embodiment, the backlight module 10 is a direct-lit backlight module 10, and the substrate 12 is located above the back plate 11. The substrate 12 can be in a strip shape or a rectangular shape as a whole. The length is, for example, in the range of 200 mm - 1200 mm, and the width is, for example, in the range of 100 mm - 600 mm. When the substrate 12 is in a strip shape, it is also called a lamp strip.

[0040] Multiple substrates 12 can be set according to the size of the display device, and the multiple substrates 12 jointly provide backlight. Each substrate 12 can either be arranged on the backplane 11 at intervals. In this case, there is an interval between two adjacent substrates 12, and the diffusion plate support frame 14 can be arranged at the interval position between two adjacent substrates 12 and directly connected to the backplane 11. Of course, it can also be directly connected to the substrate 12 and thus indirectly connected to the backplane 11. Each substrate 12 can also be connected to each other in a splicing manner and arranged on the backplane 11. In this case, for example, two adjacent substrates 12 are seamlessly spliced. The diffusion plate support frame 14 is connected to the substrate 12 and thus indirectly connected to the backplane 11.

[0041] The substrate 12 is arranged on the first side of the backplane 11, and the first side of the backplane 11 is the side of the backplane 11 close to the display panel. The substrate 12 serves as the backlight source 122. Compared with using a light bar as the backlight source 122 in the side-in type backlight module 10, the substrate 12 has higher brightness. With the cooperation of zoned dynamic control, the dynamic contrast ratio of the display device can be improved.

[0042] The number of substrates 12 is not limited to one, but is, for example, multiple, specifically, for example, 2, 3, 4, 5, 6 or other numbers, and can be specifically set according to actual needs.

[0043] Specifically, the substrate 12 includes a circuit board 121 and a light source 122.

[0044] The circuit board 121 is located above the backplane 11, and the shape of the circuit board 121 is the same as the overall shape of the substrate 12.

[0045] The circuit board 121 can generally adopt a printed circuit board (Printed Circuit Board, abbreviated as PCB). According to actual needs, the circuit board 121 can adopt a single-layer board, a double-layer board or a multi-layer board, which is not limited here.

[0046] In the embodiment, the light source 122 can adopt an LED or a Mini LED. Different from an ordinary light-emitting diode, the Mini LED specifically refers to a micro light-emitting diode chip. Since the size of the Mini LED is very small, it is beneficial to control the dynamic light emission of the backlight module 10 into smaller zones and improve the dynamic contrast ratio of the picture. In this embodiment, the unilateral size of a single Mini LED is less than 500 μm.

[0047] In practical applications, the substrate 12 can include only one color of light source 122 or can include multiple colors of light sources 122, which is not limited here.

[0048] The diffusion plate 13 is disposed between the substrate 12 and the display panel. The diffusion plate 13 is located on the light-emitting side of the substrate 12 and is spaced apart from the substrate 12 by a certain distance. The setting of this distance is to enable sufficient light mixing between the light sources 122 on the substrate 12. The function of the diffusion plate 13 is to scatter the incident light so that the light passing through the diffusion plate 13 is more uniform.

[0049] The diffusion plate 13 is provided with a scattering particle material. When light is incident on the scattering particle material, refraction and reflection occur continuously, thereby achieving the effect of scattering the light and realizing the function of light homogenization. The thickness of the diffusion plate 13 is usually set to 0.5 mm - 3 mm. The greater the thickness of the diffusion plate 13, the greater the haze and the better the uniform effect.

[0050] The diffusion plate 13 can usually be processed by an extrusion process. The material used for the diffusion plate 13 is generally selected from at least one of polymethyl methacrylate (PMMA), polycarbonate (PC), polystyrene-based material (PS), and polypropylene (PP).

[0051] In this embodiment, the substrate 12 can be used to emit blue light. At this time, the diffusion plate 13 can be a quantum dot diffusion plate for realizing color conversion and diffusion functions.

[0052] The optical film is located on the side of the diffusion plate 13 facing away from the substrate 12. The size of the optical film is adapted to the display device, slightly smaller than the display device, and is usually set to be rectangular.

[0053] In specific implementation, the optical film includes one or a combination of a fluorescent film, a quantum dot film, a prism sheet, a brightness enhancement film, etc., which are set according to specific needs and are not limited herein.

[0054] To prevent the diffusion plate 13 from being recessed in the middle due to its own weight and affecting the image quality, a diffusion plate support frame 14 is provided in the middle of the diffusion plate 13. The diffusion plate support frame 14 is connected to the diffusion plate 13 and the back plate 11 respectively to prevent the deformation of the diffusion plate 13. Specifically, the diffusion plate support frame 14 can be connected between the first side of the back plate 11 and the diffusion plate 13, as shown in Figures 1 to 3 any one of the figures; or it can be connected between the first side of the substrate 12 and the diffusion plate 13. The first side of the substrate 12 refers to the side of the substrate 12 close to the display panel; or a part of the diffusion plate support frame 14 can be disposed on the first side of the back plate 11, and another part of the diffusion plate support frame 14 can be disposed on the first side of the substrate 12.

[0055] Optionally, the diffusion plate support frame 14 includes a base 141 and a support portion 142.

[0056] Please refer to Figures 1 to 5, in the first embodiment, the base 141 is disposed on the first side of the backplane 11. The base 141 includes a first mounting surface 1411 and a second mounting surface 1412. The first mounting surface 1411 is the side of the base 141 close to the backplane 11, and the first mounting surface 1411 is disposed on the first side of the backplane 11. The second mounting surface 1412 is the side of the base 141 away from the backplane 11. The support portion 142 is disposed on the base 141 and extends from the base 141 towards the diffusion plate 13. The first end of the support portion 142 is in contact with the diffusion plate 13, and the second end of the support portion 142 is disposed on the base 141.

[0057] Wherein, the extending direction 1421 of the support portion 142 is not perpendicular to the first mounting surface 1411, and the extending direction 1421 of the support portion 142 is perpendicularly disposed with respect to the second mounting surface 1412.

[0058] Since the extending direction 1421 of the support portion 142 is not perpendicular to the first mounting surface 1411 and the extending direction 1421 of the support portion 142 is perpendicularly disposed with respect to the second mounting surface 1412, it can be made that the extending direction 1421 of the support portion 142 is not perpendicular to the side surface of the diffusion plate 13 facing the backplane 11. In other words, the extending direction 1421 of the support portion 142 is inclined with respect to the side surface of the diffusion plate 13 facing the backplane 11, and is also inclined with respect to the first side of the backplane 11. In this way, when an external force is applied to the diffusion plate 13, the support portion 142 can elastically deform in a direction perpendicular to the diffusion plate 13 to buffer the external force, thereby effectively preventing defects such as deformation, bending or fracture of the diffusion plate 13.

[0059] In addition, in the second embodiment, the difference from the first embodiment is that the second mounting surface 1412 is, for example, disposed at an angle with respect to the first side of the backplane 11, that is, the two are not parallel. The relationship between the extending direction 1421 of the support portion 142 and the first mounting surface 1411 is not limited and can be flexibly adjusted and set according to actual needs. The extending direction 1421 of the support portion 142 is not perpendicular to the first side of the backplane 11. Thus, when an external force is applied to the diffusion plate 13, the support portion 142 can elastically deform in a direction perpendicular to the diffusion plate 13 to buffer the external force, thereby effectively preventing defects such as deformation, bending or fracture of the diffusion plate 13.

[0060] Of course, in the third embodiment, please refer to Figure 6, different from the first embodiment in that the base 141 is not limited to being disposed on the first side of the back plate 11, but is, for example, disposed on the first side of the substrate 12, and the first mounting surface 1411 is correspondingly disposed on the first side of the substrate 12. Thus, when an external force is applied to the diffusion plate 13, the support portion 142 can elastically deform in a direction perpendicular to the diffusion plate 13 to buffer the external force, thereby effectively preventing defects such as deformation, bending or fracture of the diffusion plate 13.

[0061] Similarly, in the fourth embodiment, different from the second embodiment in that the base 141 is not limited to being disposed on the first side of the back plate 11, but is, for example, disposed on the first side of the substrate 12, and the first mounting surface 1411 is correspondingly disposed on the first side of the substrate 12.

[0062] For the embodiment in which the first mounting surface 1411 is directly disposed on the first side of the substrate 12, in the actual production process, the diffusion plate support frame 14 can be installed on the first side of the substrate 12, and then the first side of the substrate 12 can be installed on the first side of the back plate 11. Compared with the method of installing each diffusion plate support frame 14 separately on the first side of the back plate 11, it is beneficial to improve the assembly efficiency. Among them, the first mounting surface 1411 includes but is not limited to being fixed to the first side of the substrate 12 by adhesive bonding, or by welding, or by using fasteners such as pins, rivets, and snap connectors to be fixed to the first side of the substrate 12, and can be specifically selected flexibly according to actual needs and is not limited herein.

[0063] In this embodiment, the first mounting surface 1411 is specifically fixed to the first side of the substrate 12 by adhesive bonding. In addition, all regions of the first mounting surface 1411 are adhesively connected to the first side of the substrate 12. In order to bond each position of the first mounting surface 1411 to the first side of the substrate 12, the first mounting surface 1411 is arranged at the middle position in the width direction along the first side of the substrate 12, and the width W1 of the first mounting surface 1411 is smaller than the width W2 of the first side of the substrate 12. Optionally, W1 / W2 is 0.5 to 0.9, specifically, for example, 0.5, 0.6, 0.7, 0.8 or 0.9, etc.

[0064] On the basis of any of the foregoing embodiments, specifically, the number of the diffusion plate support frames 14 is not limited to one, but is, for example, multiple, specifically, for example, 2, 3, 4, 5, 6 or other numbers, and can be flexibly adjusted and set according to actual needs. The multiple diffusion plate support frames 14 are spaced apart and arranged on the first side of the back plate 11 and are in contact with multiple different positions of the diffusion plate 13, so as to play a better supporting role for the diffusion plate 13 and effectively prevent defects such as deformation, bending or fracture of the diffusion plate 13.

[0065] On the basis of any of the foregoing embodiments, when the diffusion plate support frame 14 is in an uncompressed state, such asFigure 1 As shown, the extending directions 1421 of the supporting portions 142 of the plurality of diffusion plate support frames 14 are not perpendicular to the first side of the back plate 11 or the side of the diffusion plate 13 facing the back plate 11, that is, the plurality of supporting portions 142 are all inclined with respect to the first side of the back plate 11 or the side of the diffusion plate 13 facing the back plate 11.

[0066] Specifically, the inclination directions of the plurality of supporting portions 142 are the same when in the uncompressed state. For example, they all incline to the left side, or the right side, or the front side, or the rear side, etc. of the first side of the back plate 11, or even all incline with the same inclination angle with respect to the first side of the back plate 11 or the side of the diffusion plate 13 facing the back plate 11. More specifically, the extending directions 1421 of the plurality of supporting portions 142 are the same when in the uncompressed state. Thus, during the process of the diffusion plate 13 being subjected to a squeezing force, it will cause the plurality of supporting portions 142 to incline in the same direction, as Figure 2 shown. Furthermore, the forces exerted by each diffusion plate support frame 14 on the diffusion plate 13 are basically the same, and the forces at different positions of the diffusion plate 13 are relatively more uniform. Since it will not incline in different directions, the elastic deformation is more controllable.

[0067] Of course, as some alternative solutions, the inclination directions of the plurality of supporting portions 142 can be only partially the same or each can be different when in the uncompressed state, and can be flexibly adjusted and set according to actual requirements, which will not be limited herein. As an example, in the left-to-right direction, the first and the second supporting portions 142 both incline to the left side of the first side of the back plate 11, and the third supporting portion 142 inclines to the right side of the first side of the back plate 11. During the process of the diffusion plate 13 being subjected to a squeezing force, it will cause the first supporting portion 142 and the second supporting portion 142 to both incline and bend to the left side of the first side of the back plate 11, and the third supporting portion 142 to incline and bend to the right side of the first side of the back plate 11. The inclination directions of each supporting portion 142 are as Figure 2 shown.

[0068] As a specific example, the number of the substrates 12 is set to be plural, specifically, for example, 3 as Figure 4 shown. A plurality of diffusion plate support frames 14 are arranged between any two adjacent substrates 12 on the first side of the back plate 11. All the diffusion plate support frames 14 between two adjacent substrates 12 are arranged at intervals in the length direction of the substrate 12. Thus, not only can the forces at different positions of the diffusion plate 13 be relatively uniform, thereby preventing cracking defects, but also it can prevent the light path from being blocked due to being too close to the substrate 12.

[0069] Optionally, when all the diffusion plate support frames 14 located between two adjacent substrates 12 are arranged, they can be arranged at intervals in sequence along a direction parallel to or substantially parallel to the length direction of the substrate 12, that is, the connection lines of the centers of the respective diffusion plate support frames 14 are on the same straight line and parallel to or substantially parallel to the length direction of the substrate 12; or they can be arranged in a direction not parallel to the length direction of the substrate 12, that is, the connection lines of the centers of the respective diffusion plate support frames 14 do not need to be on the same straight line, for example, arranged in an S shape, an arc shape, a trigonometric function line shape, etc. The specific arrangement method can be flexibly adjusted and set according to actual needs. When arranging, for example, try to avoid the light path as much as possible to prevent blocking the light path, and at the same time, it can support multiple different parts of the diffusion plate 13.

[0070] It should be noted that substantially parallel means that it appears parallel to the naked eye of a person, and it is not strictly parallel in the mathematical sense, allowing a deviation of ±5° from the length direction of the substrate 12.

[0071] As a specific example, the number of substrates 12 is set to one, specifically for example as Figure 5 shown, a plurality of diffusion plate support frames 14 are respectively arranged on the opposite sides of the substrate 12 on the first side of the back plate 11. In this way, under the support of the diffusion plate support frames 14 on the opposite sides of the substrate 12, not only can the different positions of the diffusion plate 13 be stressed more evenly, thereby preventing cracking defects, but also the defect of blocking the light path due to being too close to the substrate 12 can be prevented.

[0072] In one embodiment, the number of substrates 12 is set to one or more, the diffusion plate support frames 14 are set to one or more, and the diffusion plate support frames 14 are arranged on the first side of the substrate 12. Specifically, one diffusion plate support frame 14 is correspondingly located between two adjacent light sources 122 on the first side of the substrate 12.

[0073] In some embodiments, the first mounting surface 1411 is, for example, set as a plane, and the first mounting surface 1411 is attached and fixed to the back plate 11. In this way, not only is it beneficial to stably install and fix the base 141 on the back plate 11, but also because the shape of the base 141 is relatively regular, it is beneficial to achieve mass production and the production efficiency is relatively high.

[0074] Of course, in some other embodiments, the first mounting surface 1411 can also be set as one or more arbitrary combinations of an arc surface, a stepped surface, a Z-shaped surface, an S-shaped surface, and a broken line surface, which can be set as a regular shape or an irregular shape. Specifically, it can be flexibly adjusted and set according to actual needs, as long as the second mounting surface 1412 forms an angle with the back plate 11 after the first mounting surface 1411 is connected and fixed to the back plate 11.

[0075] Please refer to Figures 7 to 9, in one embodiment, the included angle α between the second mounting surface 1412 and the surface of the back plate 11 facing the diffusion plate 13 is such that 1° ≤ α ≤ 5°. Specifically, α includes but is not limited to 1°, 3°, or 5°, etc. In this way, the included angle α is large enough and not too small, enabling the support portion 142 mounted on the second mounting surface 1412 to be inclined relative to the back plate 11, so that the support portion 142 can play an annular buffering role when the diffusion plate 13 is subjected to external force; in addition, especially when the first mounting surface 1411 is set as a plane and is fixedly attached to the back plate 11, since the included angle α is small and not too large, that is, the included angle α between the second mounting surface 1412 and the first mounting surface 1411 is small, the thickness of each part of the base 141 is relatively uniform and does not vary greatly, which is conducive to increasing the structural strength of the base 141 and improving the mounting stability of the base 141 on the back plate 11.

[0076] Of course, in some alternative solutions, α can also be set to any value greater than 5°, such as 10°, 15°, 20°, 30°, or 45°, etc.

[0077] In one embodiment, the included angle β between the side of the second mounting surface 1412 closest to the back plate 11 and the extending direction 1421 of the support portion 142 satisfies 0° < β - α < 90°, or 90° < β - α < 180°. In this way, β - α, that is, the included angle formed by the extending direction 1421 of the support portion 142 and the diffusion plate 13, is greater than 0° and less than 180°, and not equal to 90°. The extending direction 1421 of the support portion 142 is inclined relative to the diffusion plate 13, so that when an external force is applied to the diffusion plate 13, the support portion 142 can elastically deform in a direction perpendicular to the diffusion plate 13 to buffer the external force.

[0078] In one embodiment, 0° < β ≤ 90°. In this way, the support portion 142 is inclined towards the side of the second mounting surface 1412 closest to the back plate 11. Specifically, it is inclined towards the side of the base 141 with a smaller thickness, having better elastic deformation ability and better elastic effect.

[0079] In a specific embodiment, 60° ≤ β ≤ 85°. In this way, on the one hand, the value of β is small, making the value of β - α small. Then, when an external force is applied to the diffusion plate 13, the support portion 142 can elastically deform in a direction perpendicular to the diffusion plate 13 to buffer the external force; on the other hand, the value of β is large, making the value of β - α large. Then, the extending direction 1421 of the support portion 142 approaches perpendicular to the diffusion plate 13, which is beneficial to reducing light shielding and improving the viewing effect.

[0080] Of course, in some alternative solutions, 90° < β < 180°, and β - a is not equal to 90°, that is, the support portion 142 is inclined towards the side of the second mounting surface 1412 that is farther away from the back plate 11. Similarly, when an external force is applied to the diffusion plate 13, the support portion 142 can elastically deform in a direction perpendicular to the diffusion plate 13 to buffer the external force.

[0081] Please refer to Figure 7 and Figure 8 , in an embodiment, both the first mounting surface 1411 and the second mounting surface 1412 are set as planes, the distance between the first mounting surface 1411 and the second mounting surface 1412 gradually changes along the width direction x of the first mounting surface 1411, and the distance between the first mounting surface 1411 and the second mounting surface 1412 remains unchanged along the length direction y of the first mounting surface 1411. Specifically, the cross-sectional profile of the base 141 along the length direction y is trapezoidal. In this way, not only is it beneficial to stably mount and fix the base 141 on the back plate 11, but also because the shape of the base 141 is relatively regular, it is beneficial to achieve mass production with high production efficiency.

[0082] Please refer to Figure 8 and Figures 10 to 12 , Figure 8 and Figures 10 to 12 respectively show the structural diagrams when the shape of the support portion 142 is different. The support portion 142 includes but is not limited to regular shapes such as sheet-like, plate-like, cone-like, or column-like shapes and other irregular shapes, and can be specifically adjusted and set flexibly according to actual needs.

[0083] Among them, when the support portion 142 is set as a cone shape, the cross-sectional profile of the support portion 142 along its extending direction 1421 includes but is not limited to various regular shapes such as circular, elliptical, or polygonal shapes and other irregular shapes. The polygon can be a triangle, quadrilateral, pentagon, or hexagon, etc.

[0084] Please refer to Figure 1 and Figure 2 and Figure 7 and Figure 8 , in a specific embodiment, the support portion 142 is a support sheet or a support plate, and both opposite surfaces of the support portion 142 along its thickness direction are, for example, inclined towards the thinner side of the base 141. In other words, the support portion 142 is inclined towards the side of the second mounting surface 1412 that is closest to the back plate 11, thereby having better elastic deformation ability and better elastic effect. Of course, both opposite surfaces of the support portion 142 along its thickness direction can also be, for example, inclined towards the thicker side of the base 141. In other words, the support portion 142 is inclined towards the side of the second mounting surface 1412 that is farther away from the back plate 11, and can also play a role in buffering external forces.

[0085] It should be noted that the inclined setting of the supporting portion 142 in this embodiment specifically refers to the case where the plane where the diffusion plate 13 or the back plate 11 is located is used as the horizontal plane as a reference, and the extending direction 1421 of the supporting portion 142 is not perpendicular to the horizontal plane.

[0086] In a specific embodiment, when a plurality of diffusion plate support frames 14 are provided, the supporting portions 142 of the plurality of diffusion plate support frames 14 are provided as support sheets or support plates, and the thickness directions of the respective supporting portions 142 are all, for example, along the Figure 8 X-axis direction as shown. In this way, when an external force is applied to the diffusion plate 13, the supporting portions 142 of the respective diffusion plate support frames 14 can all be inclined and deformed in the same direction. Specifically, they are all inclined along the X-axis direction toward the thinner side of the base 141 or toward the thicker side of the base 141 to buffer the external force, thereby effectively preventing defects such as deformation, bending, or fracture of the diffusion plate 13.

[0087] In an embodiment, a rounded corner 1422 is provided at one end of the supporting portion 142 for abutting against the diffusion plate 13. In this way, when the diffusion plate 13 is extruded by an external force, during the process of the diffusion plate 13 coming into contact with the top end of the supporting portion 142, the arc surface of the rounded corner 1422 abuts against the diffusion plate 13, which can prevent the diffusion plate 13 from being punctured.

[0088] It should be noted that the base 141 and the supporting portion 142 in this embodiment include but are not limited to an integrated structure or a detachable connection. Among them, the base 141 and the supporting portion 142 include but are not limited to forming an integrated structure by means of bonding, welding, or integral injection molding. In addition, the base 141 and the supporting portion 142 can also be, for example, fixed by snap connection or connected and fixed by fasteners, thereby realizing a detachable connection.

[0089] In a specific embodiment, the base 141 and the supporting portion 142 are integrally injection molded. In this way, mass production can be achieved, the production efficiency is relatively high, and the diffusion plate support frame 14 has good elasticity.

[0090] In some embodiments, the base 141 includes but is not limited to being fixed to the back plate 11 by bonding, welding, or snap connection, and can also be fixed to the back plate 11 by using fasteners. Specifically, it can be flexibly adjusted and set according to actual needs and is not limited herein.
