Technical Field

[0001] The present disclosure relates to the field of display technology, and in particular to a display module and a display device including the display module. Background Art

[0002] Currently, in the field of display technology, existing display modules will cause the display panel to warp during the sliding and rolling process. If the warped area is forcibly flattened, interlayer slippage will occur between the film layers, making it easy for the film layers to peel off, resulting in damage to the display panel.

[0003] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0016] Wherein, one end of the arc channel close to the rolling axis is the first supporting portion, and one end of the arc channel away from the rolling axis is the second supporting portion.

[0020] In an exemplary embodiment of the present disclosure, the orthographic projections of the first support member and the second support member in the second direction at least overlap, and the second support structure further includes:

[0021] The transmission member is located between the first support member and the second support member and is at least in contact with the first support member and the second support member. The transmission member can rotate relative to the first support member and the second support member.

[0045] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be comprehensive and complete and will fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0046] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of the illustration to another component, these terms are used in this specification only for convenience, such as according to the orientation of the examples described in the drawings. It is understood that if the device of the illustration is turned upside down, the component described as "upper" will become the component "lower". When a structure is "on" other structures, it may mean that the structure is formed integrally on the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure through another structure.

[0047] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusion and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first" and "second", etc. are used merely as labels and are not intended to limit the quantity of their objects.

[0048] The inventor of the present disclosure has found that in the prior art, the display panel used for the roll-up display module is usually a flexible display panel. The display panel usually has multiple film layers stacked and arranged, and the lengths of the multiple film layers can be the same. When the display panel is bent 180°, due to the different bending radii of each layer, the two ends of the outer film layer in any two adjacent film layers will be retracted relative to the two ends of the inner film layer, thereby causing interlayer displacement.

[0049] In addition, since an adhesive layer is usually provided in a real panel, the adhesive layer may be, for example, a pressure sensitive adhesive (PSA). Since PSA has fluidity, in an ideal case, after the display panel is bent 180°, the inner and outer surfaces of the PSA are in the same relative position as the two adjacent film layers, and since the length of the PSA is the same as the length of the two adjacent film layers, this also causes the inner and outer surfaces of the PSA to be pulled and deformed, and torque is generated at various points inside the PSA. In response to this, in order to reduce and balance the torque, the PSA and the two adjacent film layers will naturally bend outward to reduce the interlayer displacement, thereby reducing the torque generated inside the PSA, and ultimately forming the anti-warping phenomenon.

[0050] In reality, after the display panel is bent 180°, the inner and outer surfaces of the PSA often cannot maintain the same relative position with the adjacent film layer, and the PSA and the adjacent film layer will slide relative to each other. When the bonding force between the PSA and the adjacent film layer is equal to the internal deformation stress of the PSA, the sliding stops, which will also cause the display panel 1 to warp.

[0051] In the prior art, in order to enable the display panel to slide and roll normally, the warped portion of the display panel is usually forcibly flattened. However, the inventors of the present disclosure have found that after forcibly flattening the warped portion of the display panel, the displacement between the film layers will increase, and when the display panel bends and slides back and forth, the displacement between the film layers will occur cyclically, resulting in the film layer peeling phenomenon, which eventually causes damage to the display panel, thus shortening the service life of the existing display module.

[0052] In order to solve the above technical problems discovered by him, the inventor of the present disclosure has invented a new display module after spending a lot of creative work. The display module has a better sliding effect and a longer service life.

[0053] In one embodiment of the present disclosure, Figures 1 to 6 As shown, the display module may include: a display panel 1, a scroll shaft 2 and a first support structure 3. Among them, the display panel 1 may be a flexible display panel 1, which can be bent and has a planar display portion 11 and a roll-up display portion 12 that are connected to each other. The display panel 1 may have multiple film layers, and the multiple film layers may have an adhesive layer. The adhesive layer may be, for example, a pressure sensitive adhesive (PSA for short), but is not limited thereto. The adhesive layer may also be other materials with an adhesive effect, which may be selected and set according to actual needs, all of which are within the scope of protection of the present disclosure.

[0054] At least a portion of the scroll display portion 12 may be rolled up on the scroll shaft 2 , so that the scroll display portion 12 may scroll by rolling the scroll shaft 2 .

[0055] The first support structure 3 may be located on the side of the scroll axis 2 close to the plane display portion 11, and the first support structure 3 may have at least a first support portion 31 and a second support portion 32. The first support portion 31 is close to the scroll axis 2 relative to the second support portion 32 in the first direction X, and the second support portion 32 is close to the plane display portion 11 relative to the first support portion 31 in the second direction Y. Among them, the first direction X may be the direction in which the scroll axis 2 points to the first support structure 3, and the second direction Y may be perpendicular to the first direction X. That is, it can be understood that the height of the second support portion 32 may be higher than the height of the first support portion 31. Thus, when at least part of the scroll display portion 12 warps up during the scrolling process, the first support portion 31 and the second support portion 32 may be used to support the part so that it can maintain its naturally warped shape, and the scroll display portion 12 can be parallel to the plane display portion 11 after passing through the second support portion 32.

[0056] Thus, the present disclosure can make the sliding display part 12 include a section of anti-warping area by setting the first supporting structure 3, and can make the tail end of the sliding display part 12 parallel to the flat display part 11, so that it is no longer necessary to forcibly flatten the anti-warping area, and can prevent the problem of displacement between the film layers of the display panel 1 during the flattening process, and can prevent the film layers from peeling off during use, thereby reducing the probability of damage to the display panel 1, and can increase the service life of the display module. At the same time, since the present disclosure supports the anti-warping area, and the anti-warping area no longer needs to be forcibly flattened, it can make the display panel 1 smoother during the rolling process, so that the sliding effect of the display module is better.

[0057] In one embodiment of the present disclosure, Figure 1 and Figure 2 As shown, the first support structure 3 may include: a first pulley 33 and a second pulley 34. The first pulley 33 and the second pulley 34 may be arranged at intervals, and the first pulley 33 may be the first support portion 31, and the second pulley 34 may be the second support portion 32. When the scrolling display portion 12 is reversely warped, the first pulley 33 and the second pulley 34 may support the scrolling display portion 12 that is reversely warped, so as to ensure that the scrolling display portion 12 can maintain a naturally reversed shape.

[0058] The spacing and height difference between the first pulley 33 and the second pulley 34 can be set according to actual needs. For example, the first pulley 33 can be located at the starting position of the scrolling display part 12, that is, the first pulley 33 can support the starting position of the scrolling display part 12. The second pulley 34 can be located at the end position of the scrolling display part 12, that is, when the scrolling display part 12 is reversed, the end position of the reversed gradually becomes horizontal, so that the second pulley 34 can support the end position of the scrolling display part 12, so that the tail end of the scrolling display part 12 can be kept parallel to the plane display part 11.

[0059] In this embodiment, the first supporting structure 3 may further include: a third pulley 35. The third pulley 35 may be arranged opposite to the second pulley 34 in the second direction Y, and a first gap may be provided between the third pulley 35 and the second pulley 34. A portion of the scrolling display portion 12 may pass through the first gap, and the third pulley 35 and the second pulley 34 may be respectively attached to the light emitting side and the backlight side of the scrolling display portion 12.

[0060] Therefore, by providing the third pulley 35 so as to cooperate with the second pulley 34, the shape and movement position of the scroll display portion 12 can be limited to prevent the scroll display portion 12 from having position deviation when sliding, thereby making the scroll display portion 12 slide more smoothly and preventing the display panel 1 from being damaged due to deviation in the sliding position.

[0061] In this embodiment, the first pulley 33 can limit the angle of the scrolling display part 12 around the scrolling axis 2 to be greater than or equal to 200° and less than or equal to 240°, thereby preventing the problem that the first support structure 3 is not easy to set due to the scrolling display part 12 being too small or too large. However, it is not limited to this, and the angle of the scrolling display part 12 around the scrolling axis 2 can also be other values, which can be selected and set according to actual needs, which are all within the protection scope of the present disclosure.

[0062] In this embodiment, the material of the first pulley 33, the second pulley 34 and the third pulley 35 may be rubber, so that the first pulley 33, the second pulley 34 and the third pulley 35 can be ensured to have good support force for the scroll display part 12 while preventing them from causing damage to the scroll display part 12. However, it is not limited thereto, and the material of the first pulley 33, the second pulley 34 and the third pulley 35 may also be other materials, such as plastic, etc., which can be selected and set according to actual needs, which is within the protection scope of the present disclosure.

[0063] In this embodiment, the first pulley 33, the second pulley 34 and the third pulley 35 can each have a plurality, for example, the first pulley 33, the second pulley 34 and the third pulley 35 can have two, three, etc. respectively. By providing a plurality of first pulleys 33, the second pulley 34 and the third pulley 35, the supporting capacity of the scroll display portion 12 can be improved, so that the scroll display portion 12 can be more flat.

[0064] In other embodiments of the present disclosure, Figure 3 and Figure 4 As shown, the first support structure 3 may include: a first support block 36 and a second support block 37. The first support block 36 and the second support block 37 may be arranged opposite to each other along the second direction Y. There may be an arc channel between the first support block 36 and the second support block 37, and part of the scrolling display portion 12 may be located in the arc channel. The end of the arc channel close to the scroll axis 2 may be the first support portion 31, and the end of the arc channel away from the scroll axis 2 may be the second support portion 32.

[0065] When the rolling display part 12 is warped, the first support block 36 and the second support block 37 can support the warped rolling display part 12, so as to ensure that the rolling display part 12 can maintain a naturally warped shape, and the warped end position of the rolling display part 12 can gradually become horizontal. At the same time, the first support block 36 and the second support block 37 are less difficult to manufacture and more convenient to install than the pulley, so that the manufacturing difficulty and manufacturing cost of the display module can be reduced by using the first support block 36 and the second support block 37.

[0066] In this embodiment, the surface of the first support block 36 close to the second support block 37 may have a first curvature, and the surface of the second support block 37 close to the first support block 36 may have a second curvature, and the first curvature and the second curvature may be the same. In addition, the first support block 36 and the second support block 37 may be respectively fitted with the light-emitting side and the backlight side of the scrolling display unit 12. Specifically, the first curvature and the second curvature may be the same as the curvature of the reverse warping of the scrolling display unit 12, so that the first support block 36 and the second support block 37 can be used to limit the shape and movement position of the scrolling display unit 12, and prevent the scrolling display unit 12 from having position deviation when sliding, so that the scrolling display unit 12 can slide more smoothly, and the problem of damage to the display panel 1 due to deviation in the sliding position can be prevented.

[0067] In this embodiment, the material of the first support block 36 and the second support block 37 may be rubber, so that the first support block 36 and the second support block 37 can ensure that they have good support force on the scrolling display part 12 while preventing them from causing damage to the scrolling display part 12. However, it is not limited thereto, and the material of the first support block 36 and the second support block 37 may also be other materials, such as plastic, etc., which can be selected and set according to actual needs, which is within the protection scope of the present disclosure.

[0068] In one embodiment of the present disclosure, the first support block 36 and the second support block 37 can also limit the angle of the scrolling display unit 12 around the scroll axis 2 to be greater than or equal to 200° and less than or equal to 240°, thereby preventing the problem that the first support block 36 and the second support block 37 are not easy to set due to the scrolling display unit 12 being surrounded by too small or too large angles. However, it is not limited to this, and the angle of the scrolling display unit 12 around the scroll axis 2 limited by the first support block 36 and the second support block 37 can also be other values, which can be selected and set according to actual needs, which are all within the protection scope of the present disclosure.

[0069] In one embodiment of the present disclosure, Figures 1 to 6 As shown, the display module may further include: a second support structure 4. The second support structure 4 may include: a first support member 41 and a second support member 42. The first support member 41 may be connected to the plane display portion 11, and may be located on the backlight side of the plane display portion 11, so as to support the plane display portion 11 and prevent the plane display portion 11 from bending and deformation. The second support member 42 may be connected to at least one end of the roll-up display portion 12 away from the plane display portion 11, and may be located on the backlight side of the roll-up display portion 12. By providing the second support member 42, it can be used to fix the end of the roll-up display portion 12 away from the plane display portion 11, so that the end of the roll-up display portion 12 away from the plane display portion 11 can always remain parallel to the plane display portion 11.

[0070] In this embodiment, the orthographic projections of the first support member 41 and the second support member 42 in the second direction Y may at least overlap. The second support structure 4 may further include a transmission member 43. The transmission member 43 may be located between the first support member 41 and the second support member 42, and may at least fit with the first support member 41 and the second support member 42, and the transmission member 43 may rotate relative to the first support member 41 and the second support member 42. Thus, by providing the transmission member 43, it is possible to ensure that the first support member 41 and the second support member 42 can move synchronously.

[0071] For example, when the display panel 1 is rolled up and unfolded, the transmission member 43 can rotate clockwise, so that the first support member 41 can slide in the direction away from the rolling member, and the second support member 42 can simultaneously slide in the direction close to the rolling member, thereby increasing the area of ​​the display area without pulling, and preventing the display panel 1 from being damaged during the unfolding process; when the display panel 1 is retracted, the transmission member 43 can rotate counterclockwise, so that the first support member 41 can slide in the direction close to the rolling member, and the second support member 42 can simultaneously slide in the direction away from the rolling member, thereby reducing the area of ​​the display area without pulling, and preventing the display panel 1 from being damaged during the retraction process.

[0072] In this embodiment, a first tooth portion 44 may be provided on one side of the first support member 41 close to the second support member 42, a second tooth portion 45 may be provided on one side of the second support member 42 close to the first support member 41, and a third tooth portion 46 may be provided on the outer peripheral surface of the transmission member 43. The teeth on the first tooth portion 44 and the teeth on the second tooth portion 45 can both mesh with the teeth on the third tooth portion 46. By providing the first tooth portion 44, the second tooth portion 45 and the third tooth portion 46, the sliding stroke and sliding speed of the first support member 41 and the second support member 42 can be kept consistent during the relative sliding of the first support member 41 and the second support member 42.

[0073] In one embodiment of the present disclosure, the first support member 41 can be fixed to the backlight side of the flat display portion 11 through an adhesive layer, and the second support member 42 can also be fixed to the backlight side of the roll-up display portion 12 through an adhesive layer. The adhesive layer can be PSA, which can ensure the fixing strength between the first support member 41 and the flat display portion 11, and the second support member 42 and the roll-up display portion 12. However, it is not limited to this, and the adhesive layer can also be other materials with an adhesive effect, which can be selected and set according to actual needs, which is within the protection scope of the present disclosure.

[0074] In one embodiment of the present disclosure, Figures 1 to 4 As shown, the second support member 42 may include a main body 421 and an extension 422. The main body 421 may be connected to at least one end of the scrolling display portion 12 away from the plane display portion 11, and the extension 422 may extend in a direction away from the scrolling display portion 12. The display module may further include a drive circuit 5. The drive circuit 5 may be connected to one end of the scrolling display portion 12 away from the plane display portion 11, and the drive circuit 5 may be attached to a side of the extension 422 away from the first support member 41.

[0075] Therefore, the present disclosure arranges the driving circuit 5 on the side of the extension portion 422 away from the support member, so that it can be directly connected to the display panel 1 without affecting the light output of the display panel 1. Compared with the solution of arranging the driving circuit 5 on the backlight side of the display panel 1 using the bending process, the present embodiment no longer needs to perform the bending process, which can reduce the manufacturing difficulty and manufacturing cost of the display module.

[0076] In other embodiments of the present disclosure, Figure 5 and Figure 6 As shown, the driving circuit 5 can also be connected to the end of the flat display part 11 away from the sliding display part 12, and can be attached to the backlight side of the flat display part 11, and can be located on the side of the first support member 41 away from the rolling member. Specifically, the driving circuit 5 can be arranged on the backlight side of the flat display part 11 by using a bending process, so that the driving circuit 5 will not be bumped during transportation or installation of the whole machine, thereby preventing the driving circuit 5 from being damaged, and further preventing the entire display module from being damaged.

[0077] In one embodiment of the present disclosure, Figures 1 to 6 As shown, the driving circuit 5 may include: a driving chip 51 and a flexible circuit board 52. However, the present invention is not limited thereto, and the driving circuit 5 may also include other structural components, which may be selected and arranged according to actual needs.

[0078] In one embodiment of the present disclosure, the display module may further include: a housing (not shown in the figure). The rolling shaft 2, the first pulley 33, the second pulley 34, the third pulley 35 and the transmission member 43 may be connected to the housing in a rolling manner so that the rolling shaft 2, the first pulley 33, the second pulley 34, the third pulley 35 and the transmission member 43 can rotate relative to the housing and can remain relatively stationary with the housing in the first direction X. The above-mentioned first support member 41 and the second support member 42 may be fixedly connected to the housing so that there is no relative displacement between the first support member 41 and the second support member 42 and the housing. Thus, the present disclosure can prevent the rolling shaft 2, the first pulley 33, the second pulley 34, the third pulley 35, the transmission member 43, the first support member 41 and the second support member 42 from being displaced during the sliding of the display panel 1, thereby improving the smoothness of the sliding of the display panel 1 and preventing the display panel 1 from being damaged.

[0079] The inventor of the present disclosure has invented a display device based on the above-mentioned display module. The display device may include the above-mentioned display module, and the display device may have a better sliding effect, and the display panel 1 in the display device is not easily damaged during the sliding process, thereby extending the service life of the display device.
