Description

Technical Field

[0002] With the continuous development of Mini-LED backlight modules, the advantages of glass-based light boards are becoming more and more obvious compared to printed circuit board (PCB)-based ones: the use of active matrix drive (AM: Active Matrix) eliminates screen tearing and truly achieves healthy eye protection without screen flicker; the glass-based light board simplifies the process, reduces the number of panels, and reduces the seams and color difference of panels; on the other hand, the glass-based light board has high flatness, is easy to fix the crystal, has a low risk of chip falling off, and has excellent quality.

[0003] However, glass itself is a brittle material and is easily broken, especially in TV products, where the defects of the material itself are more prominent: for TV Mini-LED backlight products, the industry's commonly used support structure (Supporter) material for supporting the diffuser to create the mixed light distance (OD) is polycarbonate (PC). The impact force of the entire device falling instantly acts on the Supporter through the diffuser, and is transmitted to the glass-based light board through the Supporter, causing the glass-based light board to break.

[0049] The present disclosure describes multiple embodiments, but the description is exemplary rather than restrictive, and it is apparent to those skilled in the art that there may be more embodiments and implementations within the scope of the embodiments described in the present disclosure. Although many possible feature combinations are shown in the drawings and discussed in the specific embodiments, many other combinations of the disclosed features are possible.

[0051] In addition, when describing representative embodiments, the specification may have presented the method and / or process as a specific sequence of steps. However, to the extent that the method or process does not rely on the specific order of the steps described in the present disclosure, the method or process should not be limited to the steps in the specific order described.

[0052] In the event of an accidental drop of a TV Mini-LED backlight product during use or during a mechanical test of the entire device, the impact force received by the entire device when it falls will act on the support structure 10' (Supporter) through the diffuser 10, and be transmitted to the glass-based light panel 20 through the support structure 10'. For example, when the front or back of the entire device falls vertically, the support structure 10' is subjected to an instantaneous impact force perpendicular to the back panel 30 transmitted from the diffuser 10; when the entire device falls vertically on a non-front or non-back side, the support structure 10' will also be subjected to an instantaneous lateral impact force, such as Figure 1 As shown. For TV Mini-LED backlight products, the back panels 30 commonly used in the industry are stamped back panels, aluminum-plastic panels and glass back panels. Among them, the aluminum-plastic panels and glass back panels are whole flat panels. After the glass-based light panel 20 is directly attached to the aluminum-plastic panels and the glass back panels, the back of the glass-based light panel 20 is not suspended, and the back panel 30 has good flatness. In this case, there is no risk of the glass-based light panel 20 being broken.

[0053] The inventors of the present disclosure have found that when the glass-based light panel 20 matches the stamped back panel, the stamped back panel itself has relatively poor flatness, and when the glass-based light panel 20 at the mounting position of the support structure 10' has an area suspended 100' or the stamped back panel has a local protrusion 20', such as Figure 2a and Figure 2b As shown. Since the existing support structure 10' is a solid structure made of white polycarbonate material, it has no elasticity. Figure 3 and Figure 4 As shown, in this case, the instantaneous impact force transmitted to the glass-based lamp panel 20 through the existing support structure 10' is likely to exceed the strength limit of the glass itself, causing the glass-based lamp panel 20 to break, affecting the normal use of the entire machine and causing the entire machine to fail the mechanical test (NG).

[0054] Please combine Figures 5 to 7 and Fig. 9 , the support assembly 40 provided in the embodiment of the present disclosure is now described. The support assembly 40 is supported between a first substrate and a second substrate that are arranged opposite to each other. The first substrate includes a back plate 30 and a glass-based light panel 20 arranged on the back plate 30. The second substrate includes a diffuser plate 10. The support assembly 40 includes a first support member 41 and a second support member 42. Among them, the first support member 41 is arranged on the first substrate. The first support member 41 includes a suspension portion 411 suspended on the first substrate, so that a portion of the first support member 41 is spaced apart from the first substrate to form a deformation space for the first support member 41.

[0055] The second support member 42 is a sheet-like planar structure, perpendicular to the first substrate and connected between the second substrate and the suspension portion 411 . The second support member 42 has a platform portion 421 at one end away from the suspension portion 411 , and the platform portion 421 is in contact with the second substrate.

[0056] In summary, the implementation of the disclosed embodiment will have the following beneficial effects: the support assembly 40 of the above-mentioned solution is applied to the backlight module. In addition to providing support for the diffuser plate 10 to prevent the diffuser plate 10 from bending and deformation, it can also reduce the risk of glass-based light panel 20 being broken when the flatness of the back panel 30 is poor. Specifically, the support assembly 40 includes a first support member 41 disposed on the first substrate and a second support member 42 in a sheet-like planar structure. The first support member 41 includes a suspension portion 411 suspended on the first substrate. The second support member 42 is perpendicular to the first substrate and connected between the second substrate and the suspension portion 411, so that when the second support member 42 is subjected to a lateral or oblique instantaneous impact force transmitted from the second substrate, the second support member 42 can bend and swing by utilizing the characteristics of its sheet-like planar structure, so that when the second support member 42 is subjected to an instantaneous impact force perpendicular to the first substrate transmitted from the second substrate, the second support member 42 can drive the suspension portion 411 to move toward the first substrate, so that the instantaneous impact force received by the backlight module in all directions can be partially absorbed by the support assembly 40, thereby comprehensively reducing the impact of instantaneous impact forces in all directions on the glass-based lamp panel 20, avoiding the occurrence of glass-based lamp panel 20 fragments, and the support assembly 40 can return to its original state after the external force is removed, thereby ensuring the support effect for the second substrate. The second support member 42 has a platform portion 421 at one end away from the suspension portion 411, and the platform portion 421 is attached to the second substrate. The arrangement of the platform portion 421 can increase the supporting area between the second support member 42 and the second substrate, improve the supporting stability, and thus improve the overall optical quality of the backlight module.

[0057] In an exemplary embodiment, please combine Figures 5 to 8 , the second support member 42 is an axisymmetric structure. The symmetry plane S of the second support member 42 is perpendicular to the second support member 42 and the first substrate, and equally divides the platform portion 421. The second support member 42 is an axisymmetric structure, so that the force exerted by the second substrate on the second support member 42 can be more evenly transmitted to the entire second support member 42, so that the bending and swinging of the second support member 42 is more stable.

[0058] The second support member 42 also has side portions 422 located on both sides of the symmetry plane S, that is, the second support member 42 has two side portions 422 symmetrically arranged about the symmetry plane S. The side portion 422 includes a straight section 4221 and a curved section 4222, the straight section 4221 is perpendicular to the first substrate and is arranged on the suspension portion 411, and the curved section 4222 is bent from the straight section 4221 to the symmetry plane S and connected to the platform portion 421. In this way, the second support member 42 forms a structure that gradually narrows from the straight section 4221 to the platform portion 421, so that the strength of the end of the second support member 42 close to the suspension portion 411 is greater, the structure is more stable, and it can ensure that there is a larger connection area between the second support member 42 and the suspension portion 411, and ensure the connection stability between the second support member 42 and the suspension portion 411. Furthermore, the second support member 42 is narrowed to the platform portion 421, so that the end of the second support member 42 close to the second substrate is easier to deform, the deformable space is larger, the response to the lateral or oblique instantaneous impact force is faster, and the lateral or oblique instantaneous impact force is absorbed faster, thereby reducing the impact of the lateral or oblique instantaneous impact force on the glass-based light board 20. In the embodiment of the present disclosure, the ratio of the distance from the end of the straight section 4221 away from the suspension portion 411 along the direction perpendicular to the first substrate to the suspension portion 411 to the distance from the platform portion 421 along the direction perpendicular to the first substrate to the suspension portion 411 is less than 0.5.

[0059] In an exemplary embodiment, please combine Figure 5 , Figure 7 and Figure 8 The thickness t2 of the second support member 42 may be about 0.5 mm to 0.8 mm. For example, the thickness t2 of the second support member 42 may be about 0.65 mm. The thickness t2 of the second support member 42 is the dimension of the second support member 42 in the direction parallel to the first substrate and parallel to the symmetry plane S.

[0060] In an exemplary embodiment, please combine Figure 5 and Figure 6 , the ratio of the maximum height h2 of the second support member 42 to the maximum length l2 of the second support member 42 can be about 1 to 2, for example, the ratio of the maximum height h2 of the second support member 42 to the maximum length l2 of the second support member 42 can be about 4 / 3. Among them, the maximum height h2 of the second support member 42 is the maximum dimension of the second support member 42 in a direction perpendicular to the first substrate, and the maximum length l2 of the second support member 42 is the maximum dimension of the second support member 42 in a direction parallel to the first substrate and perpendicular to the symmetry plane S. In the embodiment of the present disclosure, the maximum height h2 of the second support member 42 is the distance from the platform portion 421 to the suspension portion 411 along the direction perpendicular to the first substrate, and the maximum length l2 of the second support member 42 is the spacing dimension between the two straight sections 4221 along the direction parallel to the first substrate.

[0061] In an exemplary embodiment, please combine Figure 5 and Figure 6 The length l of the platform portion 421 may be about 0.5 mm to 1 mm, for example, the length l of the platform portion 421 may be about 0.75 mm. The length l of the platform portion 421 is the dimension of the platform portion 421 in a direction parallel to the first substrate and perpendicular to the symmetry plane S.

[0062] The above numerical ranges of the thickness t2 of the second support member 42 , the above numerical ranges of the ratio of the maximum height h2 of the second support member 42 to the maximum length l2 of the second support member 42 , and the above numerical ranges of the length l of the platform portion 421 can ensure the strength and workability of the second support member 42 .

[0063] In an exemplary embodiment, please combine Figures 5 to 9 The support assembly 40 further includes a bottom plate 43, which is disposed on the first substrate. The bottom plate 43 can increase the connection area between the support assembly 40 and the first substrate and improve the connection stability. The bottom plate 43 can be attached to the first substrate by hot melt adhesive and avoid the device area of ​​the first substrate. The device area can be installed with other devices such as light-emitting units, integrated circuits, and jumper resistors. The light-emitting unit can be, but is not limited to, a light-emitting diode.

[0064] The first support member 41 also includes two support walls 412, and the two ends of the suspension part 411 are connected to the bottom plate 43 through the support walls 412, and a suspension space 100 is formed between the suspension part 411 and the bottom plate 43. In this way, by setting the two support walls 412, the connection stability between the suspension part 411 and the bottom plate 43 can be guaranteed, and the deformation direction of the suspension part 411 can be limited when the suspension part 411 is deformed by force, thereby improving the deformation stability and deformation direction accuracy of the suspension part 411. In the embodiment of the present disclosure, the first support member 41 is an axisymmetric structure about the symmetry plane S. The bottom plate 43 is an axisymmetric structure about the symmetry plane S. In this way, the entire support assembly 40 is an axisymmetric structure, so that the force of the second substrate acting on the support assembly 40 can be more evenly transmitted to the entire support assembly 40, so that the bending and swinging of the second support member 42 is more stable, and the deformation of the suspension part 411 is more stable.

[0065] In an exemplary embodiment, please combine Figure 5 , Figure 6 and Fig. 9, the orthographic projection of the second support member 42 on the first substrate is located within the range of the orthographic projection of the suspension space 100 on the first substrate, so that the circumferential boundary of the position where the second support member 42 is set on the suspension portion 411 does not overlap with the support wall 412 in the direction perpendicular to the first substrate, so that the force transmitted to the suspension portion 411 through the second support member 42 can make the suspension portion 411 more easily deformed, thereby better absorbing the instantaneous impact force. In the embodiment of the present disclosure, the orthographic projection of the second support member 42 on the first substrate is located at the center of the orthographic projection of the suspension space 100 on the first substrate.

[0066] In an exemplary embodiment, please combine Figures 5 to 7 and Fig. 9 , the suspension portion 411 is parallel to the first substrate, and the support wall 412 is perpendicular to the first substrate.

[0067] The thickness t11 of the suspension portion 411 may be about 0.7 mm to 0.9 mm. For example, the thickness t11 of the suspension portion 411 may be about 0.8 mm. The thickness t11 of the suspension portion 411 is the dimension of the suspension portion 411 in a direction perpendicular to the first substrate and parallel to the symmetry plane S.

[0068] The thickness t12 of the support wall 412 may be about 0.7 mm to 0.9 mm. For example, the thickness t12 of the support wall 412 may be about 0.8 mm. The thickness t12 of the support wall 412 is the dimension of the support wall 412 in a direction parallel to the first substrate and perpendicular to the symmetry plane S. The thickness t11 of the suspension portion 411 and the thickness t12 of the support wall 412 are both relatively thin. During the bending and swinging process of the second support member 42, the suspension portion 411 will also be twisted to a certain extent, thereby reducing the risk of the connection between the second support member 42 and the suspension portion 411 being broken due to a large force.

[0069] In an exemplary embodiment, Figure 6As shown, when the light mixing distance is less than or equal to 6mm, the height h of the suspension space 100 can be about 0.4mm to 0.6mm. For example, the height h of the suspension space 100 can be about 0.5mm. When the light mixing distance is greater than 6mm and less than or equal to 15mm, the height h of the suspension space 100 can be about 0.8mm to 1.2mm. For example, the height h of the suspension space 100 can be about 1.0mm. When the light mixing distance is greater than 15mm, the height h of the suspension space 100 can be about 1.3mm to 1.8mm. For example, the height h of the suspension space 100 can be about 1.55mm. Among them, the height h of the suspension space 100 is the size of the suspension space 100 perpendicular to the first substrate. The smaller the light mixing distance, the higher the stability requirement for the light mixing distance, and therefore the more support components 40 are required to ensure the picture taste, the smaller the external force borne by a single support component 40, and the smaller the space for the support component 40 itself to be deformable, the smaller the height h of the suspension space 100. The larger the light mixing distance is, the fewer support components 40 are needed to ensure the optical quality, and the external force borne by a single support component 40 is also greater, the larger the space required for the support component 40 itself to be deformable is, and the greater the height h of the suspension space 100 is.

[0070] In an exemplary embodiment, please combine Figure 5 , Figure 7 and Figure 8 , the width w1 of the first support member 41 may be about 3 mm to 5 mm. For example, the width w1 of the first support member 41 may be about 4 mm. The width w1 of the first support member 41 is the dimension of the first support member 41 in a direction parallel to the first substrate and parallel to the symmetry plane S. The width of the suspension portion 411 is consistent with the width of the support wall 412, both being the width w1 of the first support member 41.

[0071] The length l1 of the first support member 41 and the length l3 of the bottom plate 43 are equal, and the length l1 of the first support member 41 and the length l3 of the bottom plate 43 are the dimensions of the first support member 41 and the bottom plate 43 in the direction parallel to the first substrate and perpendicular to the symmetry plane S.

[0072] In an exemplary embodiment, please combine Figures 5 to 7 The thickness t3 of the bottom plate 43 may be about 0.8 mm to 1.2 mm. The thickness t3 of the bottom plate 43 may be about 1.0 mm. The thickness t3 of the bottom plate 43 is the dimension of the bottom plate 43 in a direction perpendicular to the first substrate.

[0073] The shape of the bottom plate 43 may be, but is not limited to, a regular shape such as a triangle, a rectangle, a circle, or an ellipse, or may be any other irregular shape.

[0074] In the disclosed embodiment, the bottom plate 43 is in a rectangular shape. The width w3 of the bottom plate 43 may be approximately ±0.2 mm of the light mixing distance. For example, the width w3 of the bottom plate 43 may be approximately about the light mixing distance. The width w3 of the bottom plate 43 is the dimension of the bottom plate 43 in the direction parallel to the first substrate and parallel to the symmetry plane S.

[0075] The length l3 of the bottom plate 43 may be approximately 1.5*(light mixing distance ± 0.2 mm). For example, the length l3 of the bottom plate 43 may be approximately 1.5*light mixing distance. The length l3 of the bottom plate 43 is the dimension of the bottom plate 43 parallel to the first substrate and perpendicular to the symmetry plane S.

[0076] The ratio of the length l3 of the bottom plate 43 to the width w3 of the bottom plate 43 can be about 1.4 to 1.6. For example, the ratio of the length l3 of the bottom plate 43 to the width w3 of the bottom plate 43 can be about 1.5, wherein the length l3 of the bottom plate 43 can be about 1.5*the light mixing distance, and the width w3 of the bottom plate 43 can be about the light mixing distance. Considering that the support assembly 40 is subjected to a large instantaneous force during the falling process of the whole machine, the above-mentioned numerical ranges of the length l3 of the bottom plate 43 and the width w3 of the bottom plate 43 can ensure that the bottom plate 43 has a certain area, which can improve the adhesion between the support assembly 40 and the first substrate, avoid excessive local stress on the glass-based lamp panel 20 (under the same force, the larger the area of ​​the bottom plate 43, the smaller the local stress on the glass-based lamp panel 20), and can also avoid the area of ​​the bottom plate 43 being too large to avoid the device area.

[0077] In an exemplary embodiment, the ratio of the maximum height H of the support assembly 40 to the maximum width W of the support assembly 40 can be about 0.9 to 1.1, so that the structural stability of the support assembly 40 can be ensured. Among them, the maximum height H of the support assembly 40 is the maximum dimension of the support assembly 40 in the direction perpendicular to the first substrate, and the maximum width W of the support assembly 40 is the dimension of the support assembly 40 in the direction parallel to the first substrate and parallel to the symmetry plane S. In the embodiment of the present disclosure, the maximum height H of the support assembly 40 is the distance from the platform portion 421 to the first substrate along the direction perpendicular to the first substrate, H=h2+t11+h+t3. The maximum width W of the support assembly 40 is the width w3 of the bottom plate 43, W=w3. For example, the ratio of the maximum height H of the support assembly 40 to the maximum width W of the support assembly 40 can be about 1. Among them, the width w3 of the bottom plate 43 can be about the light mixing distance, then the maximum width W of the support assembly 40 can be about the light mixing distance, and the maximum height H of the support assembly 40 can be about the light mixing distance.

[0078] In an exemplary embodiment, the material of the support assembly 40 is white polycarbonate or transparent polycarbonate. The color of the support assembly 40 can be selected according to optical requirements. The materials of the first support member 41, the second support member 42 and the bottom plate 43 can be the same or different.

[0079] like Fig. 9 As shown, the embodiment of the present disclosure also provides a backlight module. The backlight module includes a first substrate, a second substrate and a plurality of support components 40. The first substrate includes a back panel 30 and a glass-based light panel 20 arranged on the back panel 30. The second substrate is arranged opposite to the first substrate, and the second substrate includes a diffuser plate 10. The support component 40 is supported between the glass-based light panel 20 and the diffuser plate 10. The support component 40 can be adhered to the glass-based light panel 20 by hot melt adhesive and abut against the diffuser plate 10. The back panel 30 can be a back panel 30 with relatively poor flatness such as a stamped back panel. Due to the design of the backlight module, the force conditions of the support components 40 at different positions may be different. The material, size, etc. of the support component 40 can be designed according to the specific situation to ensure that the mixed light distance is uniform.

[0080] Even if the glass-based light board 20 is partially suspended 100' or the back plate 30 is partially protruded 20' at the installation position, the support assembly 40 of the disclosed embodiment can partially absorb the instantaneous impact force in all directions by its own structural characteristics to avoid the glass-based light board 20 from being broken. This is helpful to avoid the shortcoming of the glass itself being fragile, making the advantages of the glass-based light board 20 more obvious.

[0081] The support assembly 40 of the disclosed embodiment can reduce the stress on the glass-based lamp panel 20 without sourcing new materials and series verification; at the same time, the existing support structure 10' can be used with the attachment equipment and attachment process, without the need to modify equipment and verify new processes, thus avoiding additional costs.

[0082] The embodiment of the present disclosure also provides a display device, including a backlight module and a display panel. The display device can be a non-self-luminous display device such as a liquid crystal display or a liquid crystal television, and the backlight module provided by the embodiment of the present disclosure is used to provide backlight for the display device.
