[0002] Organic Light-Emitting Diode (OLED) display devices have been widely used in various electronic products as display components of electronic devices. Due to the bendability of OLED flexible display panels, more delicate display performance, and the technological and intelligent trends of future cars, OLED flexible display panels are very popular in automotive instrument center consoles and entertainment screen products. A car involves the installation and use of multiple display panels (PNL). Since the interior styling requires different forms of PNL, it is expensive to develop each form of PNL separately. Therefore, the bendability of the flexible PNL can be utilized to fold the flexible PNL part to match different form requirements. Since the folded part of the flexible PNL is not protected by a cover plate, it is easy to contact and collide during subsequent transportation and assembly with the back shell, resulting in PNL failure.

[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] In addition, this application may repeat reference numbers and / or reference letters in different examples. This 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. In addition, this application provides examples of various specific processes and materials, but those of ordinary skill in the art will recognize the application of other processes and / or the use of other materials.

[0031] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0032] The first aspect of the present application provides a display module, such as Figure 1 and Figure 2As shown, the display module includes a display module body 200 and a protective component 100. The display module body 200 includes a support plate 210, a protective film 220, a flexible display panel 230, a polarizer 240, an optical glue 250 and a cover plate 260 stacked in sequence, wherein the support plate 210, the protective film 220, the polarizer 240, the optical glue 250 and the cover plate 260 are corresponding special-shaped structures, the flexible display panel 230 is a rectangular structure, and the flexible display panel 230 exceeds the folding portion 231 of the support plate 210 and is folded to the back of the display module body 200. The protective component 100 is covered on the folding portion 231 and fixed to the back of the display module body 200.

[0033] In the display module of this embodiment, Figure 1 and Figure 2 As shown, given the diverse shapes of display panels required in fields such as in-vehicle display devices, and in order to reduce the cost of developing display panels of various shapes separately, the display module of this application utilizes the bendability of the flexible display panel 230 to configure the support plate 210, protective film 220, polarizer 240, optical adhesive 250, and cover plate 260 to corresponding special-shaped structures. A rectangular flexible display panel 230 is used, and the folded portion 231 of the flexible display panel 230, which extends beyond the support plate 210, is folded 180° to the back of the display module body 200, thereby forming a special-shaped structure corresponding to the support plate 210 and other structures, thereby meeting the requirements of display devices for display panels of different shapes. At the same time, to protect the folded portion 231 of the flexible display panel 230 where it folds to the back of the display module, a protective assembly 100 is provided on the folded portion 231 to prevent contact and collision between the folded portion 231 and the display module, thereby ensuring the effectiveness of the flexible display panel 230 and, therefore, the performance of the display module in situations such as when mounted in a vehicle.

[0034] In the display module of this embodiment, Figure 1 and Figure 2 As shown, according to the installation position and structural design of the display device, the display module body 200 in the display device needs to adopt a special-shaped structure with two corners of the rectangle removed to adapt to the installation position or structural design requirements of the display device, compared to the traditional rectangular display module. In this embodiment, the support plate 210, protective film 220, polarizer 240, optical adhesive 250 and cover plate 260 are designed as corresponding special-shaped structures. Accordingly, a flexible display panel 230 is selected to match the size of the special-shaped structure. At the same time, the portion of the flexible display panel 230 that protrudes from the special-shaped structure is used as a folding portion 231. The folding portion 231 is folded 180 degrees to the back of the display module body 200, so that the shape of the flexible display panel 230 on the front of the display module body 200 corresponds to the above-mentioned special-shaped structure. The two folding portions 231 are hidden on the back of the display module body 200.

[0035] In other embodiments, the folding position of the flexible display panel 230 and the size of the folding portion 231 may be different, which is basically the same as the setting principle of the folding portion 231 in the display module of this embodiment and will not be repeated here.

[0036] As an optional implementation, Figure 1 As shown, a support member 270 is disposed between the folding portion 231 and the back surface of the display module body 200 .

[0037] In the display module of this embodiment, in order to prevent the flexible display panel 230 from bending excessively at the folding point and causing failure of the flexible display panel 230, a support member 270 is provided between the folding portion 231 and the back of the display module body 200. The support member 270 supports the folding portion 231, so that the folding angle of the folding portion 231 changes slowly when it is folded from the front of the display module body 200 to the back of the display module body 200, forming an arc-shaped folding transition, so as to avoid damage to the folding connection and cause failure of the flexible display panel 230.

[0038] In the display module of this embodiment, the support member 270 may be foam. The foam is used as the support member 270 to flexibly support and cushion the folding portion 231 , thereby cushioning the impact force generated by a collision on the folding portion 231 and protecting the folding portion 231 .

[0039] The second aspect of the present application provides a protection component 100, such as Figure 3 and Figure 4 As shown, the protection component 100 is used to protect the flexible display panel 230 from extending beyond the display module body 200 and folded to the folding portion 231 on the back of the display module body 200. The protection component 100 includes:

[0040] The cover shell 110 is covered on the folding portion 231 and fixed to the back of the display module body 200 . The cover shell 110 is provided with an escape opening 111 , which is used to avoid the folding portion of the folding portion 231 .

[0041] In the protective component 100 of this embodiment, the cover shell 110 is arranged on the folded portion 231 folded to the back of the display module main body 200, so that the folded portion 231 can be protected by the cover shell 110 to avoid contact and collision during subsequent transportation, assembly with the rear shell, etc., thereby avoiding failure of the flexible display panel 230, ensuring the effectiveness of the flexible display panel 230, and ensuring the performance of the display module in situations such as vehicle-mounted.

[0042] In this embodiment, if Figure 1 and Figure 2As shown, the folding portion 231 is the portion of the flexible display panel 230 that is folded onto the back of the display module body 200, and is in a right-angled triangle structure. Therefore, correspondingly, the cover 110 is roughly in a corresponding right-angled triangle. The protective component 100 is provided on the folding portion 231 to provide comprehensive protection for the folding portion 231, thereby preventing the folding portion 231 from being contacted or collided. Among them, the structure of the cover 110 matches the structure of the folding portion 231. The cover 110 cannot be too small, otherwise interference may occur between the cover 110 and the folding portion 231. The cover 110 cannot be too large, otherwise it will occupy too much space on the back of the display module body 200, which may affect the installation and use of the display module body 200.

[0043] It should be noted that the projection area of ​​the cover 110 on the back of the display module body 200 should be larger than the folding portion 231, so that the cover 110 expands outward by a certain space relative to the folding portion 231, thereby preventing the edge of the folding portion 231 from hitting the inner wall of the cover 110, and preventing the cover 110 from causing collision damage to the folding portion 231.

[0044] As an optional implementation, Figure 3 and Figure 4 As shown, the height of the cover 110 matches the thickness of the folded portion 231 relative to the display module body 200 . An adhesive tape 120 is disposed in the cover 110 and is located between the cover 110 and the folded portion 231 .

[0045] In the protective assembly 100 of this embodiment, adhesive tape 120 is provided within the housing 110, positioned between the housing 110 and the folded portion 231. The adhesive tape 120 not only secures the folded portion 231 relative to the housing 110 but also prevents direct contact between the housing 110 and the folded portion 231. Thus, the adhesive tape 120 forms a buffer layer, cushioning the stress between the housing 110 and the folded portion 231 and preventing damage to the folded portion 231 caused by collisions and extrusions of the housing 110. Furthermore, adhesive tape 120 and foam are provided on opposite sides of the folded portion 231, forming a double-sided buffer structure. When subjected to collisions and extrusions, the foam can be compressed to offset the stress generated by the collisions and extrusions. The foam further cushions the stress on the folded portion 231, thus better protecting the folded portion 231.

[0046] As an optional implementation, the thickness of the tape 120 is 0.1 mm to 0.5 mm.

[0047] In the protective component 100 of this embodiment, the thickness of the tape 120 is preferably 0.1 mm to 0.5 mm. The tape 120 of this thickness can not only cushion and maintain the fixation of the folded portion 231, but also cooperate with the foam as the support member 270 to cushion the stress on the folded portion 231.

[0048] As an optional implementation, Figure 3 and Figure 4 As shown, the housing 110 of the protective assembly 100 includes a top plate, side plates, and an arc-shaped connecting plate. The top plate's projection on the back of the display module body 200 covers the folded portion 231. The side plates surround the sides of the top plate to form a storage space within the housing 110. The arc-shaped connecting plate connects the top and side plates.

[0049] In the protective assembly 100 of this embodiment, the top plate of the cover shell 110 is supported by the side plates, and the top plate is connected to the side plates through an arc-shaped connecting plate, thereby forming a certain deformation space between the top plate and the side plates, and a part of the collision stress can be buffered by the arc-shaped connecting plate between the top plate and the side plates.

[0050] As an optional embodiment, the cover 110 is made of metal material.

[0051] In the protective assembly 100 of this embodiment, the cover 110 is made of metal material. Metal material has corresponding supporting and protective functions, and has good thermal conductivity, which can be more conducive to heat dissipation of the display module body 200. In this embodiment, the metal material can be selected from aluminum, stainless steel, etc.

[0052] As an optional embodiment, the side panel is provided with a flange 130 , and the flange 130 is used to be fixed to the back side of the display module body 200 .

[0053] In the protective assembly 100 of this embodiment, by providing a flange 130 on the side panel, the flange 130 can be utilized to expand the contact area between the side panel and the back of the display module body 200, so that the cover 110 can be fixed more firmly on the back of the display module body 200 and the local pressure on the back of the display module body 200 can be reduced.

[0054] As a further optional embodiment, the flange 130 is folded toward the outside of the cover 110 .

[0055] In the protection assembly 100 of this embodiment, by folding the flange 130 toward the outside of the housing 110 , it is possible to prevent the flange 130 from extending toward the inside of the housing 110 and contacting and colliding with the folded portion 231 , thereby damaging the folded portion 231 .

[0056] As an optional implementation, the flange 130 is fixed to the back surface of the display module body 200 by adhesive.

[0057] In the protective component 100 of this embodiment, the flange 130 is fixed to the back of the display module body 200 by adhesive, which is equivalent to the protective component 100 as a whole being fixed to the back of the display module body 200 by adhesive. This fixing method is simple and convenient, has low cost, and will not damage the overall structure of the display module body 200.
