Description

Technical Field

[0001] The present application relates to the technical field of display devices, and in particular to a Micro-LED display module and a display device. Background Art

[0002] In order to improve the comfort of users watching mobile devices such as mobile phones, the screens of mobile devices tend to be larger. However, a screen that is too large will limit its portability. In order to solve the problem of large screens being easy to watch and easy to carry, some mobile devices use folding screens. Folding screens use flexible display screens to fold. After folding, the screen size is reduced, which improves portability. When in use, the screen can be unfolded to achieve a large-size display effect.

[0003] The existing folding screens are folded toward the light emitting side of the screen or toward the backlight side of the screen. Among them, the folding screen folded toward the light emitting side of the screen will have obvious creases on the light emitting side of the screen after being folded multiple times. Summary of the invention

[0004] In order to avoid obvious creases on the light-emitting side of the screen as much as possible, the present application provides a Micro-LED display module and a display device.

[0005] A Micro-LED display module and a display device provided in this application adopt the following technical solutions:

[0006] In a first aspect, the present application provides a Micro-LED display module, comprising:

[0007] A display panel, wherein the middle portion of the display panel is a flexible folding area; and

[0008] an abutting layer, fixed to the backlight side of the display panel, the abutting layer comprising a bending section and two non-bending sections connected to the bending section, the bending section is opposite to the folding area, and the two non-bending sections are respectively located on both sides of the bending section;

[0009] The bending section is a flexible airbag, and a plurality of pairs of mounting plates are fixed in the flexible airbag, each of the mounting plates extends in the transverse direction, and the two mounting plates in a pair are spaced apart in the longitudinal direction, and the plurality of pairs of mounting plates are spaced apart in the transverse direction, and are all located in the middle of the bending section, and a plurality of through holes are opened on a side of the flexible airbag facing away from the display panel, and each of the through holes is located between each pair of mounting plates;

[0010] Each pair of the mounting plates is provided with a corresponding covering plate, and each pair of the mounting plates includes a first mounting plate and a second mounting plate, one end of the covering plate is fixedly connected to the first mounting plate, and the other end of the covering plate is connected to the flexible airbag and the second mounting plate through a telescopic film, and the telescopic film has a reset state and a stretched state;

[0011] When the abutment layer is in the unfolded state, the telescopic membrane is in the reset state, and the covering plate abuts against the second mounting plate to block the through hole; when the abutment layer is in the folded state, the telescopic membrane is in the stretched state, and the covering plate is away from the second mounting plate.

[0012] By adopting the above technical solution, since the folding area of ​​the display panel is flexible, the bending section against the top layer is opposite to the folding area, and multiple mounting plates in the bending section extend laterally. The mounting plates are rigid and can provide lateral support for the flexible folding area, thereby reducing screen damage.

[0013] On the other hand, the mounting plate is used to mount the cover plate. Folding of the display panel will cause squeezing of the flexible airbag. When the display panel and the abutment layer are in the folding process, the first mounting plate rotates to drive the cover plate away from the second mounting plate, so that the expansion membrane between the cover plate and the second mounting plate is gradually stretched, so that the gas squeezed out of the flexible airbag can enter the expansion membrane, thereby reducing the pressure in the flexible airbag and avoiding stress concentration to damage the display panel as much as possible.

[0014] During the unfolding process of the display panel and the top layer, the covering plate continuously approaches the second mounting plate and finally covers the through hole, and the telescopic film returns to a reset state. The covering plate can press the gas in the telescopic film into the flexible airbag, and the flexible airbag can push the folding area of ​​the display panel, so that the crease in the middle of the folding area is lifted up, so that the crease stretches and recovers, thereby achieving the effect of improving the crease.

[0015] Optionally, when the abutment layer is in the unfolded state, the covering plate, the first mounting plate, and the second mounting plate are flush with one another on a side facing away from the display panel.

[0016] By adopting the above technical solution, the thickness of the display module can be reduced, thereby reducing the thickness of the display device and achieving a thinner display device.

[0017] Optionally, the covering plate and the first mounting plate are integrally formed.

[0018] By adopting the above technical solution, the connection strength between the covering plate and the first mounting plate can be enhanced, thereby ensuring the stability of the covering plate rotating with the first mounting plate.

[0019] Optionally, the second mounting plate is provided with a support notch, and the end of the covering plate is located in the support notch.

[0020] By adopting the above technical solution, when the abutment layer is in the unfolded state, the second mounting plate acts as a limiter for the covering plate, thereby preventing the abutment layer from continuing to bend toward the side facing away from the display panel and affecting the display panel.

[0021] Optionally, the second mounting plate is provided with a receiving notch at the supporting notch, and when the abutting layer is in the unfolded state, the telescopic membrane is located in the receiving notch.

[0022] By adopting the above technical solution, when the telescopic film returns to the reset state, it is located in the accommodating notch, which can avoid the telescopic film being clamped between the covering plate and the second mounting plate as much as possible, so that the covering plate can push the gas of the flexible airbag to lift the folding area of ​​the display panel.

[0023] Optionally, the second mounting plate is provided with a first magnetic attraction portion, and the covering plate is provided with a second magnetic attraction portion that magnetically cooperates with the first magnetic attraction portion.

[0024] By adopting the above technical solution, the first magnetic attraction part and the second magnetic attraction part cooperate with each other to promote the closing of the covering plate on the second mounting plate, thereby ensuring the driving force of the covering plate on the gas in the flexible airbag and restoring the fold.

[0025] Optionally, a mounting groove is formed on the inner bottom wall of the flexible airbag, and one end of the first mounting plate and the second mounting plate facing away from the covering plate are fixed in the mounting groove.

[0026] By adopting the above technical solution, the connection between the mounting plate and the flexible airbag is facilitated, and the stability of the mounting plate in the flexible airbag is improved.

[0027] Optionally, it also includes multiple rows of support plates, each of which extends in the transverse direction and is fixed in the flexible airbag to support the flexible airbag. Multiple support plates in each row of the support plates are spaced apart in the longitudinal direction, and multiple rows of the support plates are spaced apart in the transverse direction.

[0028] By adopting the above technical solution, the flexible folding area can be supported laterally, thereby reducing screen damage.

[0029] Optionally, a row of the support plates is provided between every two adjacent pairs of the mounting plates.

[0030] By adopting the above technical solution, a uniform supporting effect and a uniform pressure pushing effect can be provided to the display panel, so that the creases at various locations in the folding area of ​​the display panel are improved.

[0031] In a second aspect, the present application also provides a display device, comprising the Micro-LED display module as described above.

[0032] By adopting the above technical solution, the supporting effect on the folding area of ​​the display panel can be improved, the screen damage phenomenon can be reduced; the impact of stress concentration on the display panel can be reduced; the crease can be stretched and restored, thereby achieving the effect of improving the crease.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] 1. When the display panel and the abutment layer are unfolded, the cover plate squeezes the gas in the telescopic film into the flexible airbag, increasing the pressure in the flexible airbag, which can push the folding area of ​​the display panel, lift up the crease in the middle of the folding area, stretch and restore the crease, and achieve the effect of improving the crease.

[0035] 2. When the display panel and the top layer are bent, the cover plate is away from the second mounting plate, the telescopic film is in a stretched state, and the gas in the flexible airbag is squeezed into the telescopic film, which can reduce the pressure in the flexible airbag and avoid stress concentration to damage the display panel.

[0036] 3. Multiple mounting plates and support plates are provided in the flexible airbag, which can provide lateral support for the flexible folding area of ​​the display panel and reduce screen damage.

[0037] 4. The cover plate and the second mounting plate cooperate with each other through magnetic attraction, which can enhance the connection stability between the cover plate and the second mounting plate when the display panel and the top layer are unfolded, ensure the driving force of the cover plate on the gas in the flexible airbag, and make the crease stretch and recover.

[0049] The present application may repeat reference numerals and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0050] The embodiments of the present application disclose a Micro-LED display module and a display device. The display device includes a Micro-LED display module. The innovation lies in the Micro-LED display module. The Micro-LED display module is described in detail below.

[0051] Example 1

[0052] Reference Figure 1, the Micro-LED display module includes a display panel 100 and an abutment layer 200. The middle of the display panel 100 is a flexible folding area 101, and the two ends are non-folding areas 102.

[0053] The supporting layer 200 is fixed to the backlight side of the display panel 100, and the supporting layer 200 includes a bending section 201 and two non-bending sections 202 connected to the bending section 201, the bending section 201 is opposite to the folding area 101, and the two non-bending sections 202 are respectively located on both sides of the bending section 201, and the non-bending sections 202 are opposite to the non-folding area 102.

[0054] Reference Figure 2 The bending section 201 is a flexible airbag 1, and multiple pairs of mounting plates 2 are fixed in the flexible airbag 1. Each mounting plate 2 extends in the transverse direction. The two mounting plates 2 in a pair are spaced in the longitudinal direction. The spacing direction of the two non-folding areas 102 is in the longitudinal direction. The multiple pairs of mounting plates 2 are spaced in the transverse direction (combined with Figure 1 and Figure 4 , Figure 1 The X direction is the horizontal direction, and the Y direction is the longitudinal direction), both are located in the middle of the bending section 201, and each pair of mounting plates 2 includes a first mounting plate 21 and a second mounting plate 22.

[0055] Since the folding area 101 of the display panel 100 is flexible, the bending section 201 of the top layer 200 is opposite to the folding area 101, and multiple mounting plates 2 in the bending section 201 extend laterally. The mounting plates 2 are rigid and can provide lateral support for the flexible folding area 101, thereby reducing screen damage.

[0056] Reference Figure 2 In order to improve the stability of the mounting plate 2 in the flexible airbag 1, a mounting groove 1a is opened on the inner bottom wall of the flexible airbag 1, and the ends of the first mounting plate 21 and the second mounting plate 22 facing away from the covering plate 3 are fixed in the mounting groove 1a, so as to facilitate the installation of the mounting plate 2 in the flexible airbag 1. The mounting plate 2 and the flexible airbag 1 can be connected by gluing or other means.

[0057] A plurality of through holes (not shown) are provided on the side of the flexible airbag 1 facing away from the display panel 100, each through hole being located between each pair of mounting plates 2, and the side walls of the flexible airbag 1 at the locations where the through holes are provided are fixedly connected to the mounting plates 2, and the flexible airbag 1 except for the through holes is sealed in other areas.

[0058] Reference Figure 2 Each pair of mounting plates 2 is provided with a corresponding cover plate 3, one end of the cover plate 3 is fixedly connected to the first mounting plate 21 (combined with Figure 3), the other ends of the covering plate 3 are connected to the flexible airbag 1 and the second mounting plate 22 through the telescopic film 4. The covering plate 3 can be in a square, circular or other shape. Taking the present embodiment as an example, the covering plate 3 is square, and the covering plate 3 has four ends, which are the first end, the second end, the third end and the fourth end in sequence, wherein the first end and the third end are opposite, the second end and the fourth end are opposite, the first end is fixedly connected to the first mounting plate 21, the third end is connected to the second mounting plate 22 through the telescopic film 4, and the second end and the fourth end are both connected to the flexible airbag 1 through the telescopic film 4, so the telescopic film 4 is U-shaped in cross section, the telescopic film 4 can be accordion-shaped, or the telescopic film 4 can be flexible. Therefore, the through hole of the flexible airbag 1 is sealed by the telescopic film 4 and the covering plate 3.

[0059] Reference Figure 2 When the display panel 100 and the abutting layer 200 are in the unfolded state, the telescopic film 4 is in the reset state, and the covering plate 3 abuts against the second mounting plate 22 to block the through hole.

[0060] In an optional embodiment, when the support layer 200 is in the unfolded state, the cover plate 3, the first mounting plate 21, and the second mounting plate 22 are flush with each other on the side facing away from the display panel 100, which can reduce the thickness of the display module, thereby reducing the thickness of the display device and achieving a thin display device. The cover plate 3 is flush with the side of the flexible airbag 1 facing away from the display panel 100. In other embodiments, in order to arrange the telescopic film 4, the cover plate 3, the first mounting plate 21, and the second mounting plate 22 can also be arranged to protrude from the flexible airbag 1.

[0061] Reference Figure 5 The second mounting plate 22 is provided with a support notch 22a, and the end of the cover plate 3 is located in the support notch 22a (combined with Figure 2 ), when the abutting layer 200 is in the unfolded state, the second mounting plate 22 acts as a limiter for the covering plate 3, which can prevent the abutting layer 200 from continuing to bend toward the side facing away from the display panel 100 and affecting the display panel 100. In other embodiments, the covering plate 3 can also abut against the end surface of the second mounting plate 22.

[0062] Reference Figure 5 The second mounting plate 22 is provided with a support notch 22a and a receiving notch 22b. When the top layer 200 is in the unfolded state, the telescopic membrane 4 is located in the receiving notch 22b (combined with Figure 2 ), when the telescopic film 4 returns to the reset state, it is located in the accommodating notch 22b, which can avoid the telescopic film 4 being clamped between the covering plate 3 and the second mounting plate 22 as much as possible, so that the covering plate 3 can push the gas of the flexible airbag 1 to lift the folding area 101 of the display panel 100.

[0063] It can be understood that when the display panel 100 and the abutment layer 200 are in the unfolded state, the telescopic film 4 is in the reset state, and the position where the telescopic film 4 is connected to the flexible airbag 1 can be located inside the flexible airbag 1 .

[0064] In an optional embodiment, the second mounting plate 22 is provided with a first magnetic portion, and the covering plate 3 is provided with a second magnetic portion that magnetically cooperates with the first magnetic portion. The magnetic cooperation between the first magnetic portion and the second magnetic portion can promote the covering plate 3 to cover the second mounting plate 22, promote the display panel 100 and the support layer 200 to return to the unfolded state, and at the same time ensure that the covering plate 3 has a driving force on the gas in the flexible airbag 1, so that the crease can stretch and recover.

[0065] Reference Figure 3 The display panel 100 and the abutment layer 200 are folded from an unfolded state to a bent state. The folding of the display panel 100 will cause squeezing of the flexible airbag 1. When the display panel 100 and the abutment layer 200 are in the folding process, the cover plate 3 rotates with the first mounting plate 21 and moves away from the second mounting plate 22, so that the telescopic film 4 is in a stretched state from the reset state, so that the gas squeezed out of the flexible airbag 1 can enter the telescopic film 4, thereby reducing the pressure in the flexible airbag 1 and avoiding stress concentration to damage the display panel 100 as much as possible.

[0066] To enhance the connection strength between the cover plate 3 and the first mounting plate 21 and ensure the stability of the cover plate 3 rotating with the first mounting plate 21, the cover plate 3 and the first mounting plate 21 are integrally formed. In other embodiments, the cover plate 3 and the first mounting plate 21 may also be independent and connected by bonding or other means.

[0067] The implementation principle of a Micro-LED display module in the embodiment of the present application is:

[0068] The flexible airbag 1 is provided with a mounting plate 2, which can provide lateral support for the flexible folding area 101 of the display panel 100, thereby reducing screen damage. During the folding process of the display panel 100 and the abutting layer 200, the gas in the flexible airbag 1 enters the telescopic film 4, which can reduce the pressure in the flexible airbag 1 and avoid stress concentration from damaging the display panel 100. During the unfolding process of the display panel 100 and the abutting layer 200, the covering plate 3 continuously approaches the second mounting plate 22 and finally covers the through hole, and the telescopic film 4 returns to the reset state. The covering plate 3 can press the gas in the telescopic film 4 into the flexible airbag 1, and the flexible airbag 1 can push the folding area 101 of the display panel 100, so that the crease in the middle of the folding area 101 is lifted up, so that the crease is stretched and restored, thereby achieving the effect of improving the crease.

[0069] Example 2

[0070] Reference Figure 6The difference between Example 2 and Example 1 is that multiple rows of support plates 5 are further provided in the flexible airbag 1, each support plate 5 extends in the transverse direction, is fixed in the flexible airbag 1, and is used to support the flexible airbag 1. Multiple support plates 5 in each row of support plates 5 are spaced in the longitudinal direction, and multiple rows of support plates 5 are spaced in the transverse direction, which can provide transverse support for the flexible folding area 101 (combined with Figure 7 and Figure 8 ), reducing screen damage. Specifically, in an optional embodiment, a row of support plates 5 is provided between each two adjacent pairs of mounting plates 2, which can provide uniform support and uniform pressure pushing effect on the display panel 100, so that the folds at various locations of the folding area 101 of the display panel 100 are improved.

[0071] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
