Description

[0001] This application is a divisional application of China, filed on May 7, 2020, with application number 202080000673.0, entitled "Support member, support assembly, display module and display device for display module". Technical Field

[0002] This invention relates to the field of display device technology, and more specifically, to a support member for a display module, a support assembly for a display module, a display module having the support member or the support assembly for the display module, and a display device having the display module. Background Technology

[0003] With the emergence of foldable devices, there is increasing exploration into the different shapes of the bending area. Currently, there are two main types of bending area shapes: U-shaped bending and water-drop bending. Water-drop bending is mainly used in the design of devices where the display folds inward. Compared to U-shaped bending, water-drop bending can provide more effective space for other components of the device, thus facilitating the thinning and lightening of inward-folding devices.

[0004] The teardrop-shaped bend is more complex in terms of geometry, and the distribution of strain and stress in the stacked structure of flexible display modules is also more complex. This shape itself places higher demands on the design of foldable display modules. For example, since the main bending area and the teardrop-shaped bending area are actually adjacent reverse bending areas, stress concentration is prone to occur at the boundary between the areas, causing the adhesive layer of the flexible display module to delaminate. Summary of the Invention

[0005] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a support member for a display module, which can achieve local bending reliability, stress dispersion in the bending area, improved support, and recovery capability after bending. Furthermore, while achieving deformation with different bending radii and opposite bending directions, it can effectively reduce horizontal stress concentration in the teardrop-shaped bending area, thus solving the problem of delamination in the laminated structure of the display module.

[0046] Display module 1, support member 10 for display module, elastic hole 11, transition area 12, first bending area 100, second bending area 200, flat area 300, flexible display panel 20, support component 30 for display module, reinforcing member 400, sub-reinforcing piece 401, first reinforcing piece 410, second reinforcing piece 420, flexible buffer layer 500. Detailed Implementation

[0047] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0048] The support member 10 for a display module according to a first aspect of the present invention is described below with reference to the accompanying drawings. The display module is switchable between a folded state and an unfolded state, and the support member 10 is located on the backlight side of the flexible display panel of the display module.

[0049] like Figures 1-5 and Figure 12 As shown, the support member 10 for display modules according to an embodiment of the present invention includes: a first bending area 100, a second bending area 200 and a flat area 300.

[0050] Specifically, there are multiple second bending areas 200, distributed on opposite sides of the first bending area 100. For example, there may be two second bending areas 200, located on the left and right sides of the first bending area 100, respectively. There are also multiple planar areas 300, distributed on the side of the second bending area 200 away from the first bending area 100. For example, there may be two planar areas 300, one located to the left of the left-hand second bending area 200 and the other to the right of the right-hand second bending area 200. It can be understood that the planar areas 300 here are relative to the bending areas.

[0051] When the display module is in a folded state, the bending direction of the first bending area 100 is opposite to that of the second bending area 200. That is, the bending direction of the first bending area 100 when bending is opposite to that of the second bending area 200 when bending. For example, the first bending area 100 bends inward, and the second bending area 200 bends outward. Here, "inward" can be understood as facing the interior of the display module in its folded state, and "outward" can be understood as facing the exterior of the display module in its folded state. For example, there are two second bending areas 200 and two planar areas 300. When the display module is folded, the left and right sides of the first bending area 100 (when folded) are opposite each other in the vertical direction, the two second bending areas 200 are opposite each other in the vertical direction, and the two planar areas 300 are opposite each other in the vertical direction. The space enclosed by the first bending area 100, the two second bending areas 200, and the two planar areas 300 constitutes the interior space of the display module. At this time, the bending axis of the first bending area 100 is located inside the display module, and the bending axis of the second bending area 200 is located outside the display module. The apex of the semicircular arc of the first bending area 100 (corresponding to the main bending area) corresponds to the bending axis of the display module, and the second bending area 200 corresponds to the teardrop-shaped bending area.

[0052] At least one of the first bending region 100, the second bending region 200, and the planar region 300 is provided with an elastic hole 11. Multiple sets of elastic holes 11 are provided, and these multiple sets of elastic holes 11 are arranged along a first direction (e.g., Figure 5 The arrangement shown is in direction A), each group includes multiple elastic holes 11, and the multiple elastic holes 11 in each group are arranged along a second direction (e.g., Figure 5The arrangement shown is in direction B), where the first and second directions are different, and the first and second directions can be perpendicular to each other or inclined to each other. For example, the elastic hole 11 is a through hole (through the support member) or a semi-through hole (e.g., a groove). That is, multiple elastic holes 11 can be provided in one of the regions of the first bending region 100, the second bending region 200, and the planar region 300, or multiple elastic holes 11 can be provided in two regions of the first bending region 100, the second bending region 200, and the planar region 300 respectively, or multiple elastic holes 11 can be provided in each region of the first bending region 100, the second bending region 200, and the planar region 300, and the multiple elastic holes 11 are arranged in a grid to achieve a patterned design. It can be understood that the patterned distribution design of the elastic holes 11 in different regions can be the same or different.

[0053] Therefore, the support member 10 used for the display module adopts a patterned design with regional design to adapt to the different support and bending resistance requirements of the main bending area, teardrop-shaped bending area and flat area 300, and to match different bending radii and different geometric shapes.

[0054] According to the embodiment of the present invention, the support member 10 for the display module can achieve local bending reliability by patterning the local area, thereby dispersing stress in the bending area, improving support, and enhancing recovery ability after bending. Furthermore, by matching the patterned designs of different areas with the patterned designs of adjacent areas, it is possible to achieve different bending radii and deformations in opposite bending directions while effectively reducing the horizontal stress concentration in the teardrop-shaped bending area and solving the problem of delamination in the stacked structure of the display module.

[0055] According to some embodiments of the present invention, such as Figure 12 As shown, a transition zone 12 is provided between the first bending zone 100 and the second bending zone 200. The transition zone 12 is a solid part, which can more effectively reduce the horizontal stress concentration in the teardrop-shaped bending area and solve the problem of delamination of the display module's laminated structure while achieving different bending radii and opposite bending directions. The shape, size, and arrangement of the elastic holes 11 in the first bending zone 100 are the same as those in the second bending zone 200.

[0056] According to some embodiments of the present invention, the first bending region 100, the second bending region 200, and the planar region 300 can be integral metal parts, thereby simplifying the structure, increasing support strength, and enhancing recovery capability after bending, thus better addressing stress concentration and the problem of delamination in the display module's laminated structure. Here, the support member 10 for the display module can be a hard metal, such as stainless steel, titanium, magnesium, aluminum, or alloys of other metals.

[0057] According to some embodiments of the present invention, the elastic hole 11 may be filled with a flexible element to reduce local stress concentration within the hole. The flexible element may be made of a polymer material, such as rubber, silicone, or PU.

[0058] In some specific embodiments of the present invention, the thickness of the flexible component is 0.001mm-0.5mm, so as to ensure surface flatness while ensuring a certain degree of elasticity.

[0059] According to some embodiments of the present invention, the shape of the elastic hole 11 can be any one of circular, elliptical, rectangular, arc-ended rectangular, and polygonal. Specifically, an arc-ended rectangular hole refers to an oblong hole, that is, the hole is elongated, with arc-shaped contours at both ends and a straight contour between the two ends. It is understood that the shapes of the elastic holes 11 in different regions can be the same or different, and the shapes of multiple elastic holes 11 in the same region can be the same or different. Those skilled in the art can make reasonable adjustments according to actual bending and support requirements.

[0060] In one specific embodiment of the present invention, such as Figure 5 As shown, the shape of the elastic hole 11 in the first bending region 100 is exactly the same as the shape of the elastic hole 11 in the second bending region 200, and both are rectangular through holes with rounded ends.

[0061] According to some embodiments of the present invention, the shapes of the first bending region 100, the second bending region 200 and the planar region 300 are respectively rectangular, elliptical and polygonal. It can be understood that the shapes of the first bending region 100, the second bending region 200 and the planar region 300 may be the same or different from each other, the shapes of multiple second bending regions 200 may be the same or different, and the shapes of multiple planar regions 300 may be the same or different.

[0062] like Figures 6-11 As shown, the support assembly 30 for a display module according to a second aspect embodiment of the present invention includes: a support member 10 and a reinforcing member 400 for a display module as described in the first aspect embodiment of the present invention.

[0063] Specifically, the reinforcing member 400 is located on the side of the support member 10 facing away from the flexible display panel of the display module, that is, the support member 10 is located between the reinforcing member 400 and the flexible display panel. The reinforcing member 400 includes a first reinforcing piece 410 and a second reinforcing piece 420, which are respectively connected to the back side of the support member 10.

[0064] like Figure 7As shown, when the display module is in the unfolded state, the side surface of the first reinforcing piece 410 facing the support member 10 and the side surface of the second reinforcing piece 420 facing the support member 10 are located in the same plane to at least support the first bending area 100. Here, "at least support the first bending area 100" means that when the display module is in the unfolded state, the support member 10 and the reinforcing piece 400 are flattened respectively. At this time, the horizontal projection of the first bending area 100 and the horizontal projection of the reinforcing piece 400 at least partially coincide, so that the reinforcing piece 400 provides support for the flattened first bending area 100. Of course, the reinforcing piece can also provide support for bending areas other than the first bending area 100, which can be achieved by adjusting the connection position between the reinforcing piece and the support member 10.

[0065] like Figure 6 As shown, when the display module is in the folded state, the first reinforcing piece 410 and the second reinforcing piece 420 are open, with the side surfaces of the first reinforcing piece 410 facing the support member 10 and the second reinforcing piece 420 facing the support member 10 opposite each other. Here, the opposite positions of the side surfaces of the first reinforcing piece 410 and the second reinforcing piece 420 facing the support member 10 include: the side surfaces of the first reinforcing piece 410 and the second reinforcing piece 420 facing the support member 10 are directly opposite each other; the side surfaces of the first reinforcing piece 410 and the second reinforcing piece 420 facing the support member 10 are offset; the side surfaces of the first reinforcing piece 410 and the second reinforcing piece 420 facing the support member 10 are parallel to each other; and the side surfaces of the first reinforcing piece 410 and the second reinforcing piece 420 facing the support member 10 are inclined to each other. For example, during the folding or flattening process, the support member 10 drives the first reinforcing piece 410 and the second reinforcing piece 420 to open or flatten, and the reinforcing pieces open when the support member 10 is folded.

[0066] According to the embodiment of the present invention, the support component 30 for the display module, using the support member 10 for the display module as described above, can achieve local bending reliability, stress dispersion in the bending area, improved support, and recovery capability after bending. Furthermore, while achieving deformation with different bending radii and opposite bending directions, it can effectively reduce horizontal stress concentration in the teardrop-shaped bending area and solve the problem of delamination of the display module's laminated structure. In addition, the first reinforcing sheet 410 and the second reinforcing sheet 420 can not only improve the flatness and support of the bending area, but also enhance the impact resistance of the bending area when flattened.

[0067] According to some embodiments of the present invention, such as Figure 6As shown, the connection between the reinforcing member 400 and the supporting member 10 is located between the first bending area 100 and the second bending area 200. That is, the connection between the first reinforcing piece 410 and the supporting member 10 is located between the first bending area 100 and the second bending area 200, and / or, the connection between the second reinforcing piece 420 and the supporting member 10 is located between the first bending area 100 and the second bending area 200. For example, the connection between the first reinforcing piece 410 and the supporting member 10, and the connection between the second reinforcing piece 420 and the supporting member 10, are arranged on opposite sides of the first bending area 100. When a transition area 12 is provided between the first bending area 100 and the second bending area 200, the first reinforcing piece 410 and the second reinforcing piece 420 can be connected to the transition areas 12 on both sides respectively to supplement the support and impact resistance of the bending area.

[0068] According to some embodiments of the present invention, such as Figure 9 and Figure 10 As shown, when the display module is in the unfolded state, the first reinforcing piece 410 and the second reinforcing piece 420 are shaped to match, that is, the first reinforcing piece 410 and the second reinforcing piece 420 are spliced ​​together, which facilitates folding and unfolding and improves support and impact resistance.

[0069] In some embodiments of the present invention, the fit gap between the first reinforcing piece 410 and the second reinforcing piece 420 is less than 10 mm when the display module is in the unfolded state, so as to ensure support and impact resistance. Further, the fit gap between the first reinforcing piece 410 and the second reinforcing piece 420 is less than or equal to 2 mm when the display module is in the unfolded state.

[0070] According to some embodiments of the present invention, the thickness of each of the first reinforcing sheet 410 and the second reinforcing sheet 420 is 0.05mm-0.5mm to ensure sufficient support and reduce the storage space occupied when folded.

[0071] According to some embodiments of the present invention, such as Figure 8 As shown, a flexible buffer layer 500 is provided between the reinforcing member 400 and the supporting member 10. That is, at least one of the first reinforcing piece 410 and the second reinforcing piece 420 is provided with a flexible buffer layer 500 between itself and the supporting member 10. For example, flexible buffer layers 500 are provided between the first reinforcing piece 410 and the supporting member 10, and between the second reinforcing piece 420 and the supporting member 10, respectively. The flexible buffer layer 500 is fixed to the back of the supporting member 10, and the flexible buffer layer 500 corresponds to the position of the first bending area 100, so as to fill the gap between the reinforcing member 400 and the supporting member 10 and improve reliability.

[0072] According to some embodiments of the present invention, such as Figure 11As shown, at least one of the first reinforcing piece 410 and the second reinforcing piece 420 is composed of a plurality of sub-reinforcing pieces 401 connected sequentially. It is understood that the plurality of sub-reinforcing pieces 401 can be connected to each other via a fixed shaft. For example, the first reinforcing piece 410 and the second reinforcing piece 420 are each composed of a plurality of sub-reinforcing pieces 401 connected sequentially, thus providing a smaller storage space in the folded state. In some specific embodiments of the present invention, the reinforcing member 400 and the support member 10 can be metal parts, such as stainless steel, aluminum alloy, magnesium alloy, or titanium alloy. The fixing method between the reinforcing member 400 and the support member 10 can be by adhesive bonding, metal riveting, or welding.

[0073] A display module 1 according to a third aspect embodiment of the present invention includes: a support member 10 for a display module and a flexible display panel 20 as described in a first aspect embodiment of the present invention. Alternatively, a display module 1 according to a third aspect embodiment of the present invention includes: a support component 30 for a display module and a flexible display panel 20 as described in a second aspect embodiment of the present invention.

[0074] Specifically, the flexible display panel 20 has a top-emitting structure, with the first bending region 100, the second bending region 200, and the planar region 300 respectively attached to the backlight surface (non-emitting surface) of the flexible display panel 20. For example, the flexible display panel 20 is an OLED panel. Therefore, the teardrop-shaped bending structure is patterned into sections (main bending region, teardrop-shaped bending region, and planar region 300) to match the bending states of different sections.

[0075] According to the present invention, the display module 1 can achieve local bending reliability by using the support member 10 for the display module as described above, thereby achieving stress dispersion, improved support and recovery capability in the bending area. Furthermore, while achieving deformation with different bending radii and opposite bending directions, it can effectively reduce the horizontal stress concentration in the teardrop-shaped bending area and solve the problem of delamination in the stacked structure of the display module.

[0076] Other configurations and operations of the display module 1 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0077] A display device according to a fourth aspect of the present invention includes a display module 1 as described in a third aspect of the present invention.

[0078] According to the display device of the present invention, by utilizing the display module 1 as described above, the bending reliability of local areas can be achieved, stress dispersion in the bending area can be realized, support can be improved and recovery ability after bending can be achieved, and while achieving different bending radii and opposite bending directions of deformation, the horizontal stress concentration in the teardrop-shaped bending area can be effectively reduced, thus solving the problem of delamination of the display module's laminated structure.
