Description

Technical Field

[0001] This application relates to the field of display technologies, and in particular, to a display device. Background Art

[0002] Competition in current display products is becoming increasingly fierce. In the industry, an F-shaped bent backplane structure is generally adopted to achieve the advantages of an ultra-narrow appearance and low cost.

[0003] In the structure of the F-shaped bent backplane, the panel is pasted on the stress-bearing surface of the backplane through a panel tape. During the assembly, turnover, and use of the TV, under the action of an external force perpendicular to the panel, the overall structure is ensured to be stable and reliable through the support of the stress-bearing surface of the backplane. In the industry, the backplane is formed by cold stamping, and the width of the stress-bearing surface is within 8 mm. The stress-bearing surface of the backplane is obtained by bending, which easily leads to insufficient strength of the stress-bearing surface. The strength of the stress-bearing surface of the backplane is a key factor affecting the reliability of the overall structure. When the strength of the stress-bearing surface is insufficient, local depression or collapse occurs under the action of an external force, resulting in abnormal problems such as tape cracking or panel light leakage.

[0056] It should be noted that the directional indications (such as up, down, left, right, front, back...) in the present invention are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0057] The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0058] In the description of the present application, it should be noted that, unless otherwise clearly specified and defined, the terms "connected" and "connected" should be understood in a broad sense.

Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0060] As Figure 1 shown, the display device includes:

[0061] A display panel 2 for displaying image information; the display panel 2 itself does not generate light sources, but receives the light from the backlight module to form an image. When external image information is input to the main control board, the main control board controls the display panel 2. After the display panel 2 receives an electrical signal, the liquid crystals inside the display panel 2 are deflected, so that the liquid crystal layer is in a state where it can allow the backlight light to pass through or block the light, and can convert the light into tiny pixel points to generate images of points, lines, and planes.

[0062] A backplane 1 provided on the rear side of the display panel 2 for supporting the display panel 22;

[0063] A rear case 5 provided on the rear side of the back side;

[0064] A middle frame 7;

[0065] A front case assembly 6 provided on the front side of the display panel 2, and the edge of the front case assembly 6 is fixedly connected to the edge of the rear case 5;

[0066] A backlight module provided between the display panel 2 and the backplane 1. The backlight module can make the brightness of the display panel 2 more uniform, reduce power consumption, and make the appearance thinner and lighter. The backlight module includes a light bar that emits light sources and an optical component 4. The optical component 4 includes a reflector, a diffuser plate, and a film. The light bar is provided on the front side of the backplane 1, and the diffuser plate is provided on the front side of the light bar. When the light bar is powered on and emits light, the light enters the diffuser plate. The diffuser plate can randomly refract the light in all directions, so that the light on the light-emitting surface of the backlight module is as uniform as possible to solve the problem of uneven light from the light-emitting sources in the light bar.

[0067] In the display device structure, in order to achieve the effects of an ultra-narrow appearance and low cost, the backplane 1 is generally thinned. However, since the backplane 1 also needs to play a role in supporting the display panel 2, in traditional display devices, the minimum thickness that the backplane 1 can achieve is 8 mm. When an external force perpendicular to the direction of the display panel 2 is applied, the strength of the stress surface of the backplane 1 is insufficient, and local depressions or collapses are likely to occur, resulting in abnormal problems such as the cracking of the tape 3 or the light leakage of the display panel 2.

[0068] An embodiment of the present application proposes a display device to solve the problem of insufficient strength of the force-bearing surface of the backplane 1 and local depression, and the display device mainly improves the structure of the backplane 1.

[0069] Among them, as Figures 2 to 5 shown, the backplane 1 includes:

[0070] A backplane body 10, the backplane body 10 is a flat plate-like structure, and is arranged at an interval behind the display panel 2 during installation;

[0071] Side plates 11, arranged on the front side of the backplane body 10, formed by protruding forward from the edge of the backplane body 10. Specifically, the side plates 11 are formed on the top, left, and right sides of the backplane body 10;

[0072] A support plate 13, arranged opposite to the backplane 1, the support plate 13 has a first end 13a and a second end 13b arranged opposite to each other, and the first end 13a of the support plate 13 is connected to the inner wall of the side plate 11. The second end 13b of the support plate 13 is a free end. A tape 3 for fixing the display panel 2 is provided on the side surface of the support plate 13 facing away from the backplane body 10. The top, left, and right sides of the display panel 2 are respectively fixedly connected to the support plates 13 on the top, left, and right sides of the backplane 1 through the tape 3, and the support plate 13 plays a supporting role for the display panel 2.

[0073] On the left side of the display device, the first end 13a of the support plate 13 is located on the left side of the second end 13b; the support plate 13 is bent forward or backward at least once between the first end 13a and the second end 13b to form a first support portion 131 and at least one second support portion 132 stacked with the first support portion 131.

[0074] Exemplarily, in combination with Figure 3 and Figure 4 , when the support plate 13 is bent once, a first support portion 131 and a second support portion 132 are formed. When the support plate 13 is bent twice, a first support portion 131 and two second support portions 132 are formed. As shown in combination with Figure 2 , when the support plate 13 is bent n times, a first support portion 131 and n second support portions 132 are formed, where n is a positive number greater than 0.

[0075] The bending direction of the support plate 13 can be forward bending or backward bending. When the support plate 13 is bent backward, the second support portion 132 is formed at the rear side of the first support portion 131, and the tape 3 is arranged on the front side surface of the first support portion 131; when the support plate 13 is bent forward, the second support portion 132 is formed at the front side of the first support portion 131, and the tape 3 is arranged on the front side surface of the foremost second support portion 132.

[0076] Exemplarily, in combination with Figure 3 As shown, the bending direction of the support plate 13 is backward, and the second support portion 132 is formed at the rear side of the first support portion 131; in combination with Figure 4 As shown, the bending direction of the support plate 13 is forward, and the second support portion 132 is formed at the front side of the first support portion 131.

[0077] It should be noted that the first support portion 131 is formed between the first end 13a of the support plate 13 and the first bending point from the first end 13a to the second end 13b, and the second support portion 132 is formed between the first bending point from the first end 13a to the second end 13b to the second end 13b, that is, between any two bending points between the first bending point and the second end 13b, and between the last bending point and the second end 13b.

[0078] In order to ensure that when an external force acts, the back plate 1 is recessed, resulting in the cracking and failure of the tape 3, and further causing the phenomenon of light leakage. In some embodiments of the present application, the width of the second support portion 132 needs to be set according to the position of the tape 3 and the width of the tape 3. Specifically, at least part of the projection of the tape 3 on the back plate body 10 coincides with the projection of the second support portion 132 on the back plate body 10, so as to enhance the strength of the support plate 13 corresponding to the tape 3 and avoid the cracking and complete failure of the tape 3 due to the depression of the support plate 13.

[0079] That is to say, at least part of the support plate 13 at the position opposite to the tape 3 is thickened. This part of the support plate 13 is not easily recessed under the action of an external force. Even if other positions are recessed or collapsed, it does not affect the overall sealing effect of the tape 3.

[0080] Furthermore, in some embodiments of the present application, in order to further improve the strength of the support plate 13, the bending angles of all the bending points formed between the first end 13a and the second end 13b of the support plate 13 are all 180°, so that the second support portion 132 is attached to the first support portion 131, thereby forming a support plate 13 with double thickness and achieving the effect of the strength of the support plate 13.

[0081] Furthermore, in combination with Figure 5 As shown, in some embodiments of the present application, the width of the second support portion 132 is A1, and the width of the tape 3 is C. To meet the strength requirements of the support plate 13, the value of A1 should be at least not less than C / 3, so as to truly strengthen the strength of the support plate 13.

[0082] Exemplarily, taking the left side of the display device as an example, when the value of A1 is too small, the overlapping surface of the second support portion 132 and the first support portion 131 is small and concentrated at the free end of the support plate 13. In this way, only the strength of the free end of the support plate 13 can be enhanced. When an external force acts on the display panel 2, the thickness of the support plate 13 on the left side of the second support portion 132 is not increased, and the support strength is still insufficient, which is likely to cause local depression, and further lead to phenomena such as cracking and light leakage of the tape 3.

[0083] Further, in some embodiments of the present application, the projection of the tape 3 on the backplane body 10 is located within the projection of the second support portion 132 on the backplane body 10. That is to say, the second support portion 132 is provided at a position corresponding to the tape 3, so as to thicken the support plate 13 at the position corresponding to the tape 3, thereby improving the strength of the support plate 13 at the position corresponding to the tape 3, and avoiding the depression of the support plate 13 at the position corresponding to the tape 3 when subjected to an external force, which affects the sealing effect of the tape 3.

[0084] Further, in the embodiments of the present application, in order to improve the strength of the support plate 13 at various positions, the width of the second support portion 132 is preferably as large as possible, but the width of the second support portion 132 needs to be smaller than the width of the first support portion 131. In the most preferred embodiment, the width of the second support portion 132 is infinitely close to the width of the first support portion 131, but the second support portion 132 and the side plate 11 can be in contact without requiring fixation.

[0085] Specifically, the minimum distance between the second support portion 132 and the side plate 11 is x, and 0 < x < C / 3. When x > C / 3, the overall width of the second support portion 132 is small, which will affect the strength of the support plate 13.

[0086] Further, since the support plate 13 is bent to form a first support portion 131 and at least one second support portion 132, which is equivalent to doubling the thickness of the support plate 13. Therefore, the overall thickness of the backplane 1 can be thinned. In some embodiments of the present application, the material of the backplane 1 is galvanized steel sheet, and the thickness of the backplane 1 is less than or equal to 0.6 mm. Even if the thickness of the backplane 1 is thinned, due to the doubling of the thickness at the support plate 13, it can still enhance the support strength and can also avoid the layout depression.

[0087] Further, in some preferred embodiments of the present application, the support plate 13 is bent backward between the first end 13a and the second end 13b to form a first support portion 131 and a second support portion 132 located between the first support portion 131 and the backplane body 10, and there is a gap between the second support portion 132 of the layer far from the first support portion 131 and the backplane body 10, that is, there is a gap between the rearmost second support portion 132 and the backplane body 10, which does not affect the fixed installation of the backlight assembly.

[0088] Considering the installation of the backlight assembly and the overall thickness of the display device comprehensively, in some embodiments of the present application, it is only necessary to bend the support plate 13 backward once to form a layer of the first support portion 131 and a layer of the second support portion 132. The bending angle of the support plate 13 bent backward is 180°, so that the second support portion 132 is attached to the rear side of the first support portion 131, achieving an effective effect of improving the strength.

[0089] The support plate 13 can be separately provided from the backplane body 10 and the side plate 11 and fixed together by welding or other fixing means, or it can also be formed by bending the backplane body 10 by a stamping process. The backplane 1 formed by bending the backplane body 10 is an F-shaped backplane.

[0090] Exemplarily, in some embodiments of the present application, the side plate 11 is formed by bending forward the top side, the left side and the right side of the backplane body 10, and the side plate 11 is bent inward by 180 degrees to form a connecting plate 12. The connecting plate 12 is attached to the inner wall of the side plate 11, and the connecting plate 12 is bent by 90° to form a support plate 13. The support plate 13 is formed at one end of the connecting plate 12 close to the backplane body 10, and there is a certain distance between the support plate 13 and the foremost end of the side plate 11 to form an installation groove for placing the display panel 2 on the front side of the backplane 1.

[0091] In some embodiments of the present application, after bending the support plate 13 to form the first support portion 131 and the second support portion 132, it is also necessary to flatten the second support portion 132 so that the first support portion 131 and the second support can be attached.

[0092] In addition, to solve the problem of local depression of the support plate 13 after being stressed, it can also be achieved without the above-mentioned bending method.

[0093] Specifically, in some other embodiments of the present application,

[0094] As Figure 11 shown, in order to strengthen the structural strength of the support plate 13, a reinforcing plate 14 is provided on the side of the support plate 13 facing the backplane 1, that is, a reinforcing plate 14 is provided on the rear side of the support plate 13, and the reinforcing plate 14 is fixedly attached to the rear side of the support plate 13.

[0095] Among them, the projection of the tape 3 on the backplane body 10 at least partially coincides with the projection of the reinforcing plate 14 on the backplane body 10.

[0096] Specifically, the projection of the tape 3 on the backplane body 10 includes a first side 301 and a second side 301 which are oppositely arranged, and both the first side 301 and the second side 301 are parallel to the side plate 11. The projection of the reinforcing plate 14 on the backplane body 10 includes a third side 141 and a fourth side 142, and the third side 141 and the fourth side 142 are parallel to the side plate 11.

[0097] Combined with Figure 12 As shown, the first side 301 coincides with the third side 141, and the second side 301 coincides with the fourth side 142. At this time, the projection of the tape 3 on the backplane body 10 completely coincides with the projection of the reinforcing plate 14 on the backplane body 10;

[0098] Or, one of the first side 301 and the second side 301 is located between the third side 141 and the fourth side 142, and the other coincides with the third side 141 or the fourth side 142. At this time, one side of the projection of the tape 3 on the backplane body 10 coincides with the projection of the reinforcing plate 14 on the backplane body 10, and the other side falls within the projection of the reinforcing plate 14 on the backplane body 10;

[0099] Or, combined with Figure 14 and Figure 15 As shown, one of the first side 301 and the second side 301 is located between the third side 141 and the fourth side 142, and the other is located outside the third side 141 or the fourth side 142. That is to say, one side of the projection of the tape 3 on the backplane body 10 is located within the projection of the reinforcing plate 14 on the backplane body 10, and the other side is located outside the projection of the reinforcing plate 14 on the backplane body 10;

[0100] Or, combined with Figure 13 As shown, both the first side 301 and the second side 301 are located between the third side 141 and the fourth side 142. That is to say, the projection of the tape 3 on the backplane body 10 completely falls within the projection of the reinforcing plate 14 on the backplane body 10

[0101] In addition, there is another implementation manner. Combined with Figure 16 As shown, both the third side 141 and the fourth side 142 are located between the first side 301 and the second side 301.

[0102] In the above several possible embodiments, the tape 3 and the reinforcing plate 14 partially or completely overlap. At the position where the reinforcing plate 14 is provided, the supporting strength of the back plate 1 for the display panel 2 is increased. Since the reinforcing plate 14 and the tape 3 partially overlap, at the overlapping portion, the support plate 13 is not easily recessed, and the tape 3 at the overlapping portion is not easily cracked, thereby avoiding the problem of complete failure of the tape 3 and solving the problem of light leakage of the display device caused by cracking of the tape 3.

[0103] Further, in some embodiments, the width of the reinforcing plate 14 is less than or equal to the width of the support plate 13.

[0104] Furthermore, the side surface of the reinforcing plate 14 away from the side plate 11 does not protrude beyond the side surface of the support plate 13 away from the side plate 11. To avoid the reinforcing plate 14 affecting the backlight assembly in the display device, the reinforcing plate 14 blocks the backlight assembly and affects the use effect of the backlight assembly.

[0105] Further, in some embodiments of the present application, the distance between the side surface of the reinforcing plate 14 facing the side plate 11 and the inner wall of the side plate 11 is y, y≥0, that is to say, the side surface of the reinforcing plate 14 facing the side plate 11 can abut against the inner wall of the side plate 11 or form a gap with the inner wall of the side plate 11. Whether the reinforcing plate 14 abuts against the inner wall of the side plate 11 or not does not affect the function of the reinforcing plate 14.

[0106] The material of the back plate 1 is also galvanized steel sheet, and the thickness of the back plate 1 is less than or equal to 0.6 mm. Even if the thickness of the back plate 1 is thinned, since the reinforcing plate 14 is provided at the support plate 13, it can still enhance the support strength and can also avoid the effect of local depression.

[0107] In the above embodiments, the two solutions for improving the local depression of the support plate 13, whether the support plate 13 is bent or the reinforcing plate 14 is provided on the support plate 13, are both to thicken the support plate 13. By thickening the support plate 13, the strength of the support plate 13 is improved, and local depression is avoided when subjected to external force, thereby avoiding the problem of light leakage caused by cracking of the tape 3.

[0108] In addition, in order to solve the problem of insufficient strength of the stress surface of the back plate 1 and tilting and collapse, the embodiments of the present application also provide a display device.

[0109] The structure of this display device is similar to that of the display device in the above embodiments, and the same parts will not be described in detail. The difference lies in the support plate 13.

[0110] In some embodiments, in combination with Figures 6 to 10, the second end 13b of the support plate 13 is disposed opposite to the first end 13a. The support plate 13 is bent at least once between the first end 13a and the second end 13b to form a first support portion 131 and at least one second support portion 132, and the second support portion 132 abuts against the inner wall of the side plate 11 and is fixedly connected to the side plate 11.

[0111] In this way, the structure of the support plate 13 is strengthened at the first end 13a (i.e., the root of the support plate 13), the strength of the connection between the support plate 13 and the side plate 11 is improved, and the problem that the support plate 13 inclines and collapses due to the small connection strength between the support plate 13 and the side plate 11 under the action of external force is avoided.

[0112] Specifically, the second support portion 132 and the first support portion 131 may be disposed in a fitting manner or at an angle.

[0113] Exemplarily, as Figures 6 to 8 shown, in some embodiments of the present application, the bending angles of all the bending points formed between the first end 13a and the second end 13b of the support plate 13 are all 180°. That is, the formed second support portion 132 and the first support portion 131 are stacked, and each layer of the second support portion 132 is fixedly connected to the side plate 11. Among them Figure 6 the support plate 13 in is bent backward twice, Figure 7 the support plate 13 in is bent backward once, Figure 8 the support plate 13 in is bent forward once. And Figures 6 to 7 the angles of the bending points in are all 180°.

[0114] Further, in some embodiments of the present application, the support plate 13 is bent backward between the first end 13a and the second end 13b to form a first support portion 131 and a second support portion 132 located between the first support portion 131 and the back plate body 10. The second support portion 132 is formed on the rear side surface of the first support portion 131. The first support portion 131 is parallel to the back plate body 10, and the second support portion 132 may be parallel to the first support portion 131 or may be disposed at an angle with respect to the first support portion 131.

[0115] Exemplarily, as Figures 9 to 10 , the included angle between the first support portion 131 and an adjacent layer of the second support portion 132 is α, and 0° ≤ α ≤ 45°. Among them Figure 9 the support plate 13 in is bent backward multiple times, Figure 10 the support plate 13 in is bent backward once. When α increases, the strength of the support plate 13 is improved, but subject to requirements such as the assembly relationship and production process of the display device, through comprehensive mechanical calculation and verification, it is required that α is not greater than 15°. When α is not greater than 15°, the optimal support strength and the thickness of the display panel 2 can be obtained.

[0116] Further, the adjacent two layers of the second support portions 132 form an included angle β therebetween, where α ≤ β ≤ 2α. When β = α, from the first end 13a to the second end 13b of the self-supporting plate 13, the odd-numbered layers of the second support portions 132 formed are inclined with respect to the first support portion 131, and the even-numbered layers of the second support portions 132 are parallel to the first support portion 131. When β = 2α, the included angles between all the formed second support portions 132 and the first support portion 131 are the same.

[0117] In some preferred embodiments, as Figure 7 and 10 shown, the self-supporting plate 13 is bent backward once between the first end 13a and the second end 13b to form one layer of the first support portion 131 and one layer of the second support portion 132, and the second end 13b of the self-supporting plate 13 is in abutting connection and fixed with the inner wall of the side plate 11. As Figures 6 to 8 shown, the first support portion 131 can be arranged in parallel with the second support portion 132. Or, as Figure 9 and Figure 10 shown, the included angle between the second support portion 132 and the first support portion 131 is α, and the second end 13b of the self-supporting plate 13 is in abutting connection and fixed with the inner wall of the side plate 11, which improves the connection strength of the self-supporting plate 13 at the root and prevents the self-supporting plate 13 from tilting and collapsing.

[0118] The back plate 1 is also an F-shaped back plate 1 formed by a stamping process.

[0119] In addition, as Figure 17 shown, the scheme of arranging the reinforcing plate 14 on the self-supporting plate 13 can also solve the problem that the self-supporting plate 13 has low strength and tilts and collapses.

[0120] Specifically, the reinforcing plate 14 is also arranged at the rear side of the self-supporting plate 13 and fixedly connected to the self-supporting plate 13, and the third end 14a of the reinforcing plate 14 extends to the inner wall of the side plate 11 and is fixedly connected to the inner wall of the side plate 11. By abutting and fixing the reinforcing plate 14 against the inner wall of the side plate 11, the connection strength between the overall support structure formed by the self-supporting plate 13 and the reinforcing plate 14 and the side plate 11 is improved. When subjected to an external force, the problem that the self-supporting plate 13 tilts and collapses is avoided, and further, the problems of cracking and light leakage of the tape 3 are avoided.

[0121] To ensure the overall strength of the support structure, it is required that the width of the reinforcing plate 14 be as close as possible to the width of the support plate 13. That is to say, the fourth end 14b of the reinforcing plate 14 is as close as possible to the side of the support plate 13 away from the side plate 11. The fourth end 14b of the reinforcing plate 14 is the end of the reinforcing plate 14 away from the side plate 11. The projection of the fourth end 14b of the reinforcing plate 14 on the backplate body 10 is the fourth side 142, and the projection of the third end 14a of the reinforcing plate 14 on the backplate body 10 is the third side 141. However, considering the assembly effect and the use effect of the backlight assembly, in the preferred embodiment, the fourth end 14b of the reinforcing plate 14 does not protrude from the side of the support plate 13 away from the side plate 11, that is, the fourth section of the reinforcing plate 14 does not protrude from the second end 13b of the support plate 13.

[0122] Furthermore, at least part of the projection of the tape 3 on the backplate body 10 coincides with the projection of the reinforcing plate 14 on the backplate body 10. Taking the left side of the display device as an example, the fourth end 14b of the reinforcing plate 14 extends at least to a position flush with the left side of the tape 3. In this way, the support structure corresponding to the tape 3 is thickened, and thus the strength is improved. Even when subjected to an external force, the support plate 13 will not collapse entirely. At least it is not easy to collapse between the third end 14a and the fourth end 14b of the reinforcing plate 14. Even if partial inclination occurs, it will not cause the tape 3 to fail completely, avoiding the problem of light leakage of the display device.

[0123] In some preferred embodiments, the projection of the tape 3 on the backplate body 10 is located within the projection of the reinforcing plate 14 on the backplate body 10. Taking the left side of the display device as an example, the second end 13b of the reinforcing plate 14 extends to a position flush with the right side edge of the tape 3, or extends to the right side of the right side edge of the tape 3, so that the projection of the tape 3 on the backplate body 10 is completely located within the projection of the reinforcing plate 14 on the backplate body 10. This not only strengthens the structure at the connection position of the support plate 13 and the side plate 11, but also strengthens the position where the tape 3 is arranged, avoiding the inclination and collapse of the support plate 13.

[0124] The wider the width of the reinforcing plate 14, the greater the strengthening degree of the support plate 13, and the less likely the support plate 13 is to incline and dent. When the third end 14a of the reinforcing plate 14 abuts and is fixed to the side plate 11, since the fourth end 14b of the reinforcing plate 14 does not protrude from the side of the support plate 13 away from the side plate 11, therefore, the closer the second end 13b of the reinforcing plate 14 is to being flush with the side of the support plate 13 away from the side plate 11, the greater the support strength. In the most preferred solution, the third end 14a of the reinforcing plate 14 abuts and is fixed to the side plate 11, and the fourth end 14b of the reinforcing plate 14 is flush with the side of the support plate 13 away from the side plate 11. That is to say, the width of the reinforcing plate 14 is the same as the width of the support plate 13.

[0125] In some embodiments of the present application, the reinforcing plate 14 and the support plate 13 are fixed together by welding.

[0126] In summary, in the embodiments of the present application, in order to solve the problem that the force-bearing surface of the back plate 1 has insufficient force-bearing strength, resulting in depression or inclination and collapse of the force-bearing surface, and further resulting in cracking of the tape 3 or light leakage of the panel, the support plate 13 in the embodiments of the present application is thickened. The thickening method includes bending the support plate 13 to form a first support portion 131 and a second support portion 132 arranged in a stacked manner, or arranging a reinforcing plate 14 on the rear side surface of the support plate 13. To solve the problem of depression, it is only necessary to thicken the positions that are prone to depression during force-bearing, especially the positions where the tape 3 is arranged. That is to say, the second support portion 132 or the reinforcing plate 14 is arranged at these positions. To solve the problem of inclination and collapse, the second support portion 132 or the reinforcing plate 14 needs to abut against the bottom wall of the side plate 11 and be fixedly connected to the inner wall of the side plate 11.

[0127] In the embodiments of the present application, by bending the support plate 13 or arranging a reinforcing plate 14 on the rear side surface of the support plate 13, the strength of the structure of the support plate 13 is enhanced, and the problems of depression or inclination and collapse of the support plate 13 when subjected to external forces can be avoided, and the abnormal problems such as cracking of the tape 3 and light leakage of the panel caused by the depression or collapse of the support plate 13 are solved. And since the structure at the support plate 13 meets the force-bearing requirements after being strengthened, the overall thickness of the back plate 1 can be thinned. After the back plate 1 is thinned, due to the structural strengthening at the support plate 13, the support plate 13 can still play a good supporting role, which is more conducive to the ultra-thinning of the display device and reduces the production cost.

[0128] The above are only the specific embodiments of the present application, enabling those skilled in the art to understand or implement the present application. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments described herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
