Description

Structural support and panel display module

technical field

The invention relates to a structural support and a display module, in particular to a structural support for being installed in a backlight module and a panel display module with the structural support.

Background technique

In the structure of the existing liquid crystal panel display device, the liquid crystal panel module and the backlight module are stacked and combined. In practice, the two can be combined with a structural frame. When the liquid crystal panel display device adopts a thin design, the combination of the above-mentioned additional structural frame makes it difficult to reduce the volume of the device and is not suitable for the thin design structure. In practice, the thinner liquid crystal panel display device usually attaches the liquid crystal panel directly to the structural frame of the backlight module to reduce the structural thickness in the vertical direction. In addition, the control circuit module of the liquid crystal panel is also displaced to the side of the aforementioned backlight module, so as to suppress the influence of the control circuit module on the thickness of the aforementioned structure. In addition, in order to stabilize the electrical connection between the control circuit module and the liquid crystal panel, the control circuit module adopts a fixed design. The common design is to cut and bend part of the structural frame of the backlight module (usually formed by bending a metal plate) to form a carrier platform, which is used to carry and fix the control circuit module. The structural strength of the structural frame is reduced due to the holes, and the overall structural strength of the backlight module is also reduced. The thinner design makes each structural part more or less elastically deformed, such as bent, during the assembly process. During the assembly process of the shell of the liquid crystal panel display device, the elastic deformation generated by the shell will transmit the external force used for assembly to the liquid crystal panel and the backlight module arranged inside the shell. When the overall structural strength of the backlight module is insufficient to resist the deformation force, A liquid crystal panel with a relatively high structural brittleness will be broken due to the inability to cooperate with deformation. In addition, in order to improve the airtightness of the liquid crystal panel display device, the casing and the liquid crystal panel are usually bonded with double-sided tape, but most of the force applied for the bonding is supported by the liquid crystal panel and the backlight module, so that the aforementioned backlight Insufficient strength of the module causes cracking of the liquid crystal panel to occur more easily.

The panel display module 1 includes a casing 12 (shown as a dashed box in FIG. 1 ), a backlight module 14 , a display panel 16 and a structural frame 18 . The backlight module 14, the display panel 16 and the structural support 18 are all arranged in the casing 12, the casing 12 has a window 122, and the display panel 16 is exposed through the window 122; wherein an adhesive member 15 can be arranged between the display panel 16 and the casing 12 (such as double-sided tape), which can keep the panel display module 1 in a certain degree of airtightness. The backlight module 14 includes a structural outer frame 142, a light guide plate 144, and a light source device 146. The structural outer frame 142 surrounds and fixes the light guide plate 144. and located inside the structural outer frame 142 . The display panel 16 is fixed on the outer frame 142 and located on the light guide plate 144 . The structural outer frame 142 has a side portion 1422 . The structural support 18 is mounted on the side portion 1422 .

Please refer to FIG. 3 , which is a schematic cross-sectional view of the structural support 18 . The structural support 18 includes a C-shaped clamp portion 182 and a support portion 184 . The C-shaped clamping portion 182 includes an upper clamping portion 1822 and a lower clamping portion 1824. The upper clamping portion 1822 and the lower clamping portion 1824 have a C-shaped cross-sectional structure and an opening 182a. The bracket part 184 is an elastic bending structure, and the elastic bending structure has an upper connection side 1842 and a lower connection side 1844 . One side 1842a of the upper connection side 1842 is connected with one side 1844a of the lower connection side 1844, and a gap 184a is formed between the other side 1842b of the upper connection side 1842 and the other side 1844b of the lower connection side 1844, so that The upper connection side 1842 and the lower connection side 1844 are relatively elastically deformable. The upper clamping portion 1822 and the lower clamping portion 1824 are fixedly connected to the side 1842b of the upper connecting side 1842 and the side 1844b of the lower connecting side 1844 respectively, so that the bracket portion 184 protrudes relative to the opening 182a. In this embodiment, the C-shaped clip portion 182 and the bracket portion 184 are integrally formed and made by bending a metal plate, but the present invention is not limited thereto, for example, it can be made by injection molding of engineering plastics.

See pages 1 to 3. The C-shaped clip portion 182 clips the side portion 1422 through the opening 182a. The side portion 1422 has an upper surface 1422a, a lower surface 1422b opposite to the upper surface 1422a, and a side surface 1422c adjacent to the upper surface 1422a and the lower surface 1422b. The upper clamping part 1822 is close to the upper surface 1422a and part of the side surface 1422c, and the lower clamping part 1824 is close to the lower surface 1422b and part of the side surface 1422c. It is supplemented that, in this embodiment, the C-shaped clip portion 182 is approximately closely attached to the side portion 1422 , but the present invention is not limited thereto. In practice, the aforesaid close contact is not limited to the situation of close contact. In principle, it is only necessary to make the C-shaped clip 182 clamp the side part 1422, and then the structural difference between the C-shaped clip 182 and the side part 1422 can be utilized. It only needs to intervene so that the C-shaped clip part 182 cannot be easily detached from the side part 1422 . Therefore, when the clamping force of the C-shaped clamp portion 182 to clamp the side portion 1422 is sufficient, even if there is a gap between the C-shaped clamp portion 182 and the side portion 1422, the C-shaped clamp portion 182 can still be stably clamped on the side. Section 1422 on. In addition, in the actual assembly operation, the width of the opening 182a of the C-shaped clip part 182 is slightly smaller than the thickness of the side part 1422. 1844) allows the C-shaped clamping portion 182 to clamp the side portion 1422 smoothly through the opening 182a. The structural elasticity of the C-shaped clip part 182 is not only beneficial to the assembly operation, but also allows the C-shaped clip part 182 to be suitable for the side part 1422 whose thickness is within a certain range, increasing the application range of the C-shaped clip part 182 . In addition, the bracket portion 184 is approximately located in the middle of the backlight module 14 in the vertical direction 142b. A circuit board module 19 (shown in thick dotted line in FIG. 2 ) of the panel display module 1 can be disposed on the support portion 184 . In this embodiment, the circuit board module 19 is used as a control module of the display panel 16, but the present invention is not limited thereto. In addition, in practice, the bracket part 184 can also be used to fix the backlight module 14 in the housing 12, for example, the inside of the housing 12 has a protruding screw hole post 124 (shown in dashed line in FIG. 2 ), the bracket part 184 The lower connection side 1844 of the bottom can be placed on the screw hole column 124, and the bracket part 184 can be locked on the screw hole column by using screws, thereby achieving the effect of fixing the backlight module 14.

In order to increase the degree of structural integration between the C-shaped clip portion 182 and the side portion 1422 , the contact range between the C-shaped clip portion 182 and the side portion 1422 can be increased in practice. In this embodiment, the side portion 1422 has an extending direction 142a, and the C-shaped clip portion 182 and the bracket portion 184 also extend a certain length along the extending direction 142a. The longer the length, the more beneficial the C-shaped clip portion 182 and the side portion 1422 bond strength. In addition, the C-shaped clamp portion 182 can be logically considered to include a top 1826, a bottom 1828, and a side portion 1830 connecting the top 1826 and the bottom 1828, all of which are shown in dotted lines in FIG. 3, wherein the top 1826 is close to the upper surface 1422a, the bottom 1828 is in close contact with the lower surface 1422b, the side 1830 is in close contact with the side surface 1422c, and the top 1826 and the bottom 1828 form an opening 182a. The lower surface 1422b has an edge 1422d away from the side surface 1422c, and the bottom 1828 is aligned with the edge 1422d, thereby increasing the degree of structural integration between the C-shaped clip portion 182 and the side portion 1422 . It is added that, in this embodiment, the display panel 16 is fixed on the upper surface 1422a of the side portion 1422 by an adhesive member 17 (such as double-sided tape), so the top 1826 is not aligned with the upper surface 1422a away from the side surface 1422c. An edge 1422e, but in order to increase the degree of structural integration between the C-shaped clamp portion 182 and the side portion 1422, the top 1826 is still disposed adjacent to the display panel 16, so as to increase the contact area between the top 1826 and the upper surface 1422a as much as possible.

It should be added that, in practice, the space above the top 1826 can be used to increase its thickness, so as to enhance its structural strength. Please refer to FIG. 4 , which is a partial cross-sectional view of a panel display module 2 according to another embodiment. The structure of the panel display module 2 is substantially the same as that of the panel display module 1, so the panel display module 2 still uses the component symbols of the panel display module 1. The main difference between the panel display module 2 and the panel display module 1 is that the top 2826 of the C-shaped clip part 282 of the panel display module 2 (shown in a dotted line box in FIG. The thickness is greater than the thickness of the bottom 1828 in the vertical direction 142b, and will not affect the overall thickness of the panel display module 2. This increase in thickness also helps to increase the moment of inertia of the C-shaped clamp portion 282 in the vertical direction 142b, which can help strengthen itself structural strength. In this embodiment, the top 2826 is implemented by folding a metal plate, but the invention is not limited thereto. For example, when the structural support is injection molded with engineering plastics, the thickness of the top 2826 can be directly realized by the cavity size of the mold.

Please refer to FIG. 5 , which is a partial cross-sectional view of a panel display module 3 according to another embodiment. The structure of the panel display module 3 is substantially the same as that of the panel display module 1, so the panel display module 3 still uses the component symbols of the panel display module 1. The main difference between the panel display module 3 and the panel display module 1 is that the top 3826 of the C-shaped clamp portion 382 of the panel display module 3 (shown in a dotted line frame in FIG. 5 ) is aligned with the edge 1422e of the upper surface 1422a. The degree of structural integration between the C-shaped clip portion 382 and the side portion 1422 is increased. In addition, since the side portion 1422 is already occupied by the C-shaped clip portion 382 , the display panel 16 is fixed on the top 3826 by an adhesive member 37 (such as double-sided tape).

In the foregoing embodiments, the structural supports 18 , 28 , 38 clamped on the side portion 1422 can not only avoid destroying the original structural strength of the side portion 1422 , but also help to reinforce the structural strength of the side portion 1422 . In the structure of the panel display module 2 shown in FIG. 4 , increasing the thickness of the top portion 2826 has the effect of further reinforcing the structural strength of the side portion 1422 , but the present invention is not limited to the method of increasing the thickness. Please refer to FIG. 6 , which is a partial cross-sectional view of a panel display module 4 according to another embodiment. The structure of the panel display module 4 is substantially the same as that of the panel display module 1, so the panel display module 4 still uses the component symbols of the panel display module 1. The main difference between the panel display module 4 and the panel display module 1 is that the C-shaped clamping part 482 of the structural support 48 of the panel display module 4 further includes two ribs 4826 on the upper clamping part 1822, extending in the extending direction 142a, with an increased C-shaped The moment of inertia of the clamping portion 482 in the vertical direction 142 b can also increase the structural strength of the C-shaped clamping portion 482 and can also reinforce the structural strength of the side portion 1422 . The ribs 4826 are disposed on the side of the display panel 16 and will not image the panel display module 4 . In addition, in practice, the ribs 4826 can be formed by stamping methods such as bending or pulling part of the plate of the upper clamping part 1822 , so the structural support 48 as a whole can still be integrally formed. It is supplemented that, in practice, the rib 4826 can also be provided on the bracket part 184, as shown by a dotted line in FIG. Extending in the direction 142a can increase the structural strength of the support portion 184 itself (and the structural support 48 as a whole), and can also reinforce the structural strength of the side portion 1422; wherein, if space permits, the height of the rib 1846 protruding from the lower connecting side 1844 can be increased. Increase.

In the foregoing embodiments, the support portion 184 is roughly disposed at the middle of the side portion 1422 in the vertical direction 142b, but the present invention is not limited thereto. Please refer to FIG. 7 , which is a partial cross-sectional view of a panel display module 5 according to another embodiment. The structure of the panel display module 5 is substantially the same as that of the panel display module 1, so the panel display module 5 still uses the component symbols of the panel display module 1. The main difference between the panel display module 5 and the panel display module 1 is that the bottom surface 1844c of the bracket part 184 of the structural bracket 58 of the panel display module 5 is coplanar with the bottom surface 582a of the C-shaped clip part 582 . This structure facilitates the side portion 1422 (or the structural outer frame 142) to be fixed in the casing 12 via the bracket portion 184, such as locking with screws 59 (shown in dotted lines in FIG. 7 ), but the present invention does not rely on this limit. For example, in practice, the bracket portion 184 of the structural bracket 58 is still used to carry a circuit board module, or is also used for fixing to the housing 12 .

In practice, if the internal space of the casing 12 permits, the installation position of the bracket part 184 in the panelless display module 1 can be further moved up. Please refer to FIG. 8 , which is a partial cross-sectional view of a panel display module 6 according to another embodiment. The structure of the panel display module 6 is substantially the same as that of the panel display module 1, so the panel display module 6 still uses the component symbols of the panel display module 1. The main difference between the panel display module 6 and the panel display module 1 is that the top surface 1842c of the bracket part 184 of the structural bracket 68 of the panel display module 6 is coplanar with the top surface 682a of the C-shaped clip part 682 . At this time, the circuit board module 19 (shown in dotted line in FIG. 8 ) can be arranged closer to the display panel 16 to facilitate the electrical connection between the circuit board module 19 and the display panel 16 .

In the foregoing embodiments, the structure of the support portion 184 of the structural support 18, 28, 38, 48, 58, 68 itself is elastic, so that the structural support 18, 28, 38, 48, 58, 68 as a whole presents an elastic The clip structure is used for clipping on the side portion 1422 of the structural outer frame 142 , but the present invention is not limited thereto. Please refer to FIG. 9 , which is a schematic cross-sectional view of a structural support 78 according to another embodiment. The support part 784 of the structural support 78 has no structural elasticity and is directly fixed on the C-shaped clamp part 782. The C-shaped clamp part 782 itself can be designed to have a little elasticity, so as to be clamped on the side part 1422, such as a C-shaped The cross-sectional structure itself has an elastic effect, and if a material with a large elastic strain is used to make it, the aforementioned elastic effect will be more obvious. In practice, the structural support 78 can be integrally formed directly by injection molding, or it can still be formed by bending a metal plate, wherein the middle part of the support part 784 can have a joint surface produced by the folding of the plate, and its cross-sectional position It is indicated by a dotted line in FIG. 9 .
