DETAILED DESCRIPTION

[0030] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0032] With the advent of many electronic products such as smart phones and tablets, people have higher and higher requirements for the experience and comfort of electronic products. OLED (Organic Light Emitting Diode) display technology is the mainstream display technology today. OLED display devices have excellent display performance, which is mainly reflected in the fact that OLED is an active light-emitting display with the characteristics of high brightness and high contrast, short response time, high color gamut, and can be used for flexible display.

[0033] Currently, OLED display devices have widely used padbending technology, which allows devices such as driver chips and flexible circuit boards to be bent to the back of the display panel, thereby achieving a narrow bezel effect and improving user experience. However, the bending area of ​​the panel is very fragile and can easily cause defects due to accidental touches during the manufacturing process. Therefore, a display device that can effectively protect the bending area is urgently needed.

[0034] In the process of implementing this application, it was found that the bending area has a large bending degree and an unfixed bending shape, there are many metal lines, and the bending stress is large. If it is accidentally touched at the factory stage, it is easy to cause the metal wire in the bending area to break, resulting in GDS (Growing Dark Spot), causing plane bright and dark line defects, thereby affecting the quality of the display screen, such as Figure 1 As shown, in the prior art, a bracket 12 is provided at the module stage to protect the bending zone 5. However, on the one hand, the bracket 12 does not completely cover the bending zone 5 and has limited protection capability. On the other hand, the bracket 12 needs to be removed at the stage of the entire machine. At this time, not only can the bending zone 5 not be protected, but because the bracket 12 is bonded to the display panel 1, tearing the bracket 12 may easily accidentally touch the bending zone 5, the control chip, the flexible circuit board, etc., or leave problems such as residual glue and mold imprint. Therefore, the protection structure needs to be improved.

[0035] Below, through specific embodiments and combined Figures 2 to 10 To describe the technical solution of this application in detail.

[0036] In some embodiments of the present application, a display device is provided, such as Figure 2 As shown, it includes a stacked display panel 1 and a cover plate 2, wherein the display panel 1 includes a first plane area 3, a second plane area 4, and a bending area 5 connecting the first plane area 3 and the second plane area 4, and the first plane area 3 is arranged close to the cover plate 2; a protective structure 7 includes a reserved area 7-1 and a protection area 7-2, the reserved area 7-1 is fixed to a side of the second plane area 4 away from the cover plate 2, and the orthographic projection of the reserved area 7-1 on the cover plate 2 is located inside the cover plate 2; one end of the protection area 7-2 is connected to the reserved area 7-1, and the other end is against the cover plate 2, and the protection area 7-2 covers the bending area 5.

[0037] like Figure 2 As shown, the display device includes a display panel 1 and a cover plate 2. The cover plate 2 is, for example, a glass plate, used to cover the display panel 1 for protection. The display panel 1 is, for example, an OLED flexible plate, used to display images. Usually, the size of the cover plate 2 is larger than that of the display panel 1.

[0038] The display panel 1 includes a first plane area 3, a second plane area 4 and a bending area 5 connecting the first plane area 3 and the second plane area 4. The first plane area 3 is a display area for displaying images, and the second plane area 4 is a non-display area. A driving chip 6, a flexible circuit board 8, etc. are provided for circuit control. The bending area 5 connects the first plane area 3 and the second plane area 4, and is used to bend the second plane area 4 to the back of the first plane area 3 to achieve a narrow frame effect.

[0039] A protection structure 7 is disposed on the outer side of the display panel 1 . The protection structure 7 may be a bendable layered structure, including a reserved area 7 - 1 and a protected area 7 - 2 .

[0040] The orthographic projection of the reserved area 7-1 on the cover plate 2 is located inside the cover plate 2, that is, the cover plate 2 is arranged to cover the reserved area 7-1, and the reserved area 7-1 is fixedly attached to the second plane area 4. This area does not have a spatial impact on the assembly, so it does not need to be removed during the whole machine stage. It plays the role of connecting the protection area 7-2, and can avoid problems such as panel damage or residual glue caused by removing the bracket 12 in the related technology.

[0041] By setting one end of the protection zone 7-2 to be connected to the reserved zone 7-1 and the other end to be against the cover plate 2, it is possible to cover the bending zone 5 of the display panel 1 and effectively protect the bending zone 5, and the protection zone 7-2 can be retained or removed as needed without affecting the devices in the second plane zone 4; there is a certain gap space between the protection zone 7-2 and the bending zone 5, which acts as a buffer.

[0042] The orthographic projection of the protection zone 7-2 on the cover plate 2 can be located inside the cover plate 2, or partially overlap with the cover plate 2. When the orthographic projection of the protection zone 7-2 on the cover plate 2 is located inside the cover plate 2, the protection zone 7-2 does not need to be removed; when the orthographic projection of the protection zone 7-2 on the cover plate 2 partially overlaps with the cover plate 2, the protection plate 7-2 has a separated state disconnected from the reserved zone 7-1, or the protection zone 7-2 has a folded state toward the reserved zone 7-1 so that the orthographic projection of the folded protection zone 7-2 on the cover plate 2 is located inside the cover plate 2.

[0043] The display device can be a product or component with display function such as a mobile phone, a tablet computer, a laptop computer, a digital camera, a navigator, etc. The display device has a simple structure and is easy to manufacture. It can effectively protect the bending area 5, avoid the generation of poor bright and dark lines, and ensure the display effect.

[0044] In some embodiments, Figure 3 and Figure 7As shown, a driving chip 6 and a flexible circuit board 8 are provided on the side of the second plane area 4 away from the cover plate 2, and the display device also includes a covering tape 11 covering the driving chip 6 and the flexible circuit board 8; the side of the covering tape 11 away from the cover plate 2 is adhered to the reserved area 7-1, or the covering tape 11 is the reserved area 7-1.

[0045] like Figure 6 As shown, it is a display device in the related art, in which the second plane area 4 is provided with devices such as a driver chip 6 and a flexible circuit board 8. Usually, a covering tape 11 is provided to cover the driver chip 6 and the flexible circuit board 8. The covering tape 11 is generally composed of insulating Mylar, conductive copper foil, and absorbing material, and plays a role in blocking, shielding, and heat dissipation.

[0046] like Figure 3 As shown, the reserved area 7 - 1 is attached to the covering tape 11 , that is, the protective structure 7 and the covering tape 11 are split structures, which are easy to manufacture. The protective structure 7 and the covering tape 11 can be attached to the second plane area 4 by bending once respectively.

[0047] like Figure 7 As shown, the reserved area 7-1 is set as the covering tape 11, that is, the protection area 7-2 and the covering tape 11 are directly connected, and the protective structure 7 and the covering tape 11 are an integrally formed structure, which can reduce the thickness of the film layer, improve space utilization, and save materials; the protective structure 7 cooperates with the covering tape 11 to be attached to the second plane area 4 after only one bending, thereby avoiding extending the production cycle.

[0048] In some embodiments, Figure 3 and Figure 8 As shown, one end of the protection zone 7 - 2 is attached to a side of the cover plate 2 close to the display panel 1 , and the orthographic projection of the protection zone 7 - 2 on the cover plate 2 is located inside the cover plate 2 .

[0049] like Figure 4The figure shows the unfolded schematic diagram of the protection structure 7. The protection structure 7 can be made of a single-layer PET (polyethylene terephthalate) or PE (polyethylene) film, or PU foam (polyurethane foam) or acrylic foam, or a composite structure with an introduced copper foil and insulating Mylar. A first adhesive layer 9 can be set in the protection area 7-2, and a second adhesive layer 10 can be set in the reserved area 7-1. The first adhesive layer 9 and the second adhesive layer 10 are set on different surfaces of the protection structure 7. The adhesive layers are used to connect the display panel 1 and the cover plate 2 of the protection structure 7. A base adhesive can be set on the first adhesive layer 9 and the second adhesive layer 10, which can be torn off when in use. The adhesiveness of the first adhesive layer 9 is greater than 1500 gf / inch, which ensures the stability of the connection between the protection area 7-2 and the cover plate 2, and the second adhesive layer 10 has an adhesiveness greater than 1000 gf / inch because it is attached to the covering tape 11, and mainly plays a fixing role.

[0050] like Figure 3 As shown, use Figure 4 The protective structure 7, one end of the protection zone 7-2 can be attached to the inner side of the cover plate 2, and the reserved area 7-1 can be attached to the second plane area 4, and the positive projection of the protection zone 7-2 on the cover plate 2 is located inside the cover plate 2, that is, the cover plate 2 is arranged to cover the protection zone 7-2, so that the protection zone 7-2 does not need to be dismantled during the whole machine stage, the protective structure 7 can be retained all the time, there will be no interference with the spatial structure, and the protection zone 7-2 is connected inside the cover plate 2 to improve the space utilization rate and reduce the material consumption of the protection zone 7-2.

[0051] The protective structure 7 in this embodiment does not need to be torn off at the whole machine end, which can protect all process ends of the module factory and the whole machine factory, and can reduce the poor light and dark lines of OLED electronic products caused by cracks in the bending area 5. It is suitable for automotive, NB (notebook), TPC (industrial display), game consoles and other wide border electronic products.

[0052] The manufacturing process of the display device in this embodiment is as follows Figure 5 As shown, first, a limiting groove 2-1 is set at a position of the cover plate 2 near the bending area 5 of the display panel 1, and then the protective structure 7 is attached to the limiting groove 2-1; then the unbent display panel 1 and the cover plate 2 are vacuum-laminated (d-lami), and at this time, the covering tape 11 is located above the protective structure 7; the PADBending process is first performed, and the covering tape 11 is bent onto the display panel 1, and then the bending process of the protective structure 7 is performed, and the reserved area 7-1 is bent onto the covering tape 11, thereby protecting the bending area 5.

[0053] like Figure 8 As shown, the protection zone 7-2 is also bonded to the inner side of the cover plate 2. Figure 3 The difference is Figure 8The reserved area 7-1 is the covering tape 11, that is, the protective structure 7 and the covering tape 11 are integrally formed. Figure 3 The reserved area 7-1 is arranged on the covering tape 11, and the protection structure 7 and the covering tape 11 are separate structures.

[0054] In some embodiments, Figure 3 and Figure 8 As shown, a limiting groove 2-1 is provided on one side of the cover plate 2 close to the display panel 1, one end of the reserved area 7-1 is bonded to the limiting groove 2-1 through a first adhesive layer 9, and the depth of the limiting groove 2-1 is equal to the sum of the thickness of the protection area 7-2 and the thickness of the first adhesive layer 9.

[0055] like Figure 3 As shown, a limiting groove 2-1 is provided on one side of the cover plate 2 close to the display panel 1. The depth of the limiting groove 2-1 is, for example, 0.1 mm to 0.2 mm, and is not specifically limited. The limiting groove 2-1 can be a through groove or a blind groove, and is not specifically limited. The thickness of the cover plate 2 can be reduced to accommodate the protection area 7-2.

[0056] Can be used Figure 4 The protective structure 7 is bonded to the cover plate 2, and the protection zone 7-2 is bonded to the limiting groove 2-1 through the first adhesive layer 9. The limiting groove 2-1 is set on the inner side of the cover plate 2 to limit the position of the protection zone 7-2 and facilitate the bonding of the protection zone 7-2; the depth of the limiting groove 2-1 is equal to the sum of the thickness of the protection zone 7-2 and the thickness of the first adhesive layer 9, that is, the protection zone 7-2 located in the limiting groove 2-1 is flush with the inner side of the cover plate 2, further improving the space utilization rate, and will not produce raised wear bending zone 5 or first plane zone 3, etc., thereby improving the protection effect; flushing here is an ideal setting. In actual production, due to process limitations, etc., a drop of ±0.1 mm is allowed.

[0057] In some embodiments, the protection area 7 - 2 is a transparent structure, and the first adhesive layer 9 is a transparent adhesive layer.

[0058] The first adhesive layer 9 is made of, for example, OCA (Optically Clear Adhesive, a special adhesive) for bonding transparent optical elements, the protection zone 7 - 2 is made of, for example, PE, and the second adhesive layer 10 is made of ordinary double-sided tape.

[0059] Because the first adhesive layer 9 and the protection zone 7-2 are both close to the light emitting side of the display panel 1, setting the protection zone 7-2 and the first adhesive layer 9 to be transparent materials will not affect the light emitting of the first plane area 3 and the cover plate 2, thereby improving the display effect; the second adhesive layer 10 is on the backlight side of the display panel 1, and no transparent material is needed.

[0060] In some embodiments, the orthographic projection of the first planar area 3 on the cover plate 2 partially overlaps with the limiting groove 2 - 1 .

[0061] On the basis of setting the protection zone 7-2 and the first adhesive layer 9 to be both made of transparent materials, the orthographic projection of the first plane area 3 on the cover plate 2 can be set to partially overlap with the limiting groove 2-1, that is, the protection zone 7-2 also covers part of the first plane area 3. This will not affect the light output and can further reduce the space occupied by the protection zone 7-2, thereby improving space utilization.

[0062] In some embodiments, Figure 7 As shown, one end of the protection zone 7-2 is detachably attached to the side of the cover plate 2 away from the display panel 1, and a weak zone 7-3 is provided at the connection between the protection zone 7-2 and the reserved zone 7-1. The weak zone 7-3 is used to disconnect the connection between the reserved zone 7-1 and the protection zone 7-2, or to fold the protection zone 7-2 toward the reserved zone 7-1.

[0063] like Figure 7 As shown, one end of the protection zone 7-2 is attached to the outer side of the cover plate 2, which facilitates the connection of the protection structure 7. However, in this way, part of the projection of the protection zone 7-2 is located on the outer side of the cover plate 2. The protection zone 7-2 needs to be adjusted during the whole machine stage to avoid affecting the assembly.

[0064] A weak area 7-3 is set at the connection between the protection area 7-2 and the reserved area 7-1. The weak area 7-3 can be a tearing line, so that the protection area 7-2 can be removed along the weak area 7-3 at the stage of the whole machine, and it will not affect the assembly operation; the weak area 7-3 can also be a bending line, so that the protection area 7-2 can be bent onto the second plane area 4 at the stage of the whole machine, and it will not affect the assembly of the whole machine.

[0065] The thickness of the weak area 7-3 can be set to be smaller than the thickness of other areas of the protection structure 7, so that the protection area 7-2 can be easily bent or torn off through the weak area 7-3.

[0066] The tearing line and the bending line can be realized by conventional tangent technology. The tangent line, for example, includes a plurality of through holes arranged at intervals along the width direction of the display panel 1. In this way, the strength of the part can be reduced without changing the thickness of the protective structure 7, making it easy to bend or break and convenient to manufacture.

[0067] The sizes of the through holes can be the same or different, and the shapes of the through holes can be rectangular, etc., which are not specifically limited; the spacings between the through holes can be the same or different, and the through holes can be arranged in one row or in multiple rows.

[0068] In some embodiments, Figure 3As shown, the protection zone 7 - 2 is a bending structure, and the bending radius of the protection zone 7 - 2 is greater than the bending radius of the bending zone 5 .

[0069] Both the protective structure 7 and the bending zone 5 are bending structures with more matching shapes, which makes it convenient for the protection zone 7-2 to wrap the bending zone 5, thereby achieving better protection effect and improving space utilization. The display device can first bend the display panel 1 to form the bending zone 5, and then bend the protective structure 7 to form the protection zone 7-2, or the protective structure 7 can be attached to the flexible circuit board 8, and the display panel 1 and the protective structure 7 can be bent synchronously through a single bending process to synchronously form the bending zone 5 and the protection zone 7-2.

[0070] The bending radius of the protection zone 7-2 is larger than the bending radius of the bending zone 5. For example, the bending radius of the protection zone 7-2 is 0.3mm to 0.7mm larger than the bending radius of the bending zone 5, so that a certain gap space is formed between the protection zone 7-2 and the bending zone 5, providing a buffer space while covering the bending zone 5 to avoid accidental touch.

[0071] In some embodiments, Fig. 9 As shown, the protection area 7-2 includes a support block 7-4, one side of the support block 7-4 is flush with the plane where the reserved area 7-1 is located, and the other side of the support block 7-4 is against the side of the cover plate 2 close to the display panel 1.

[0072] The protection zone 7-2 includes a support block 7-4. The material of the support block 7-4 can be PC (polycarbonate), ABS (acrylonitrile-butadiene-styrene copolymer), PET, etc. It has high strength and better protection effect on the bending zone 5. One side of the support block 7-4 is set flush with the plane where the reserved area 7-1 is located, and the other side of the support block 7-4 is against the cover plate 2, which can play a supporting role and will not cause the reserved area 7-1 to deform. The flush setting here is an ideal setting. In actual production, due to process limitations, etc., a drop of ±0.1mm is allowed. Through the flush setting, the side of the protection structure 7 away from the back plate is flat, which can accommodate other components and save space.

[0073] The support block 7 - 4 may be supported against the cover plate 2 by gravity, or a first adhesive layer 9 may be provided to connect the cover plate 2 and the support block 7 - 4 , and the specific details are not limited thereto.

[0074] In some embodiments, a limiting groove 2-1 is provided at one end of the cover plate 2 close to the bending zone 5, and the support block 7-4 is bonded to the limiting groove 2-1 through a first adhesive layer 9, and the orthographic projection of the support block 7-4 on the cover plate 2 is located inside the cover plate 2.

[0075] A limiting groove 2-1 can be set on the inner side of the cover plate 2, and the support block 7-4 can be bonded in the limiting groove 2-1 through the first adhesive layer 9, so as to reduce the thickness of the film layer, improve the space utilization rate, and limit the support block 7-4, which is convenient for manufacturing; the orthographic projection of the support block 7-4 on the cover plate 2 is located inside the cover plate 2, that is, the cover plate 2 is set to cover the support block 7-4, so that there is no need to dismantle the protective structure 7, and the assembly of the whole machine is not affected.

[0076] In some embodiments, Fig. 9 As shown, the support block 7-4 abuts against the cover plate 2 but is not connected, and a weak area 7-3 is provided at the connection between the protection area 7-2 and the reserved area 7-1, and the weak area 7-3 is used to disconnect the connection between the reserved area 7-1 and the support block 7-4, or to fold the support block 7-4 toward the reserved area 7-1.

[0077] When a portion of the projection of the support block 7 - 4 is located outside the cover plate 2 , the support block 7 - 4 needs to be adjusted to avoid affecting the assembly.

[0078] A weak area 7-3 is provided at the connection between the protection area 7-2 and the reserved area 7-1.
