Abstract
Description
Technical Field
[0001] The present application relates to the technical field of electronic devices, and particularly to a display device. Background Art
[0002] In a four-curved screen, the four edges of the rectangular screen are all bent downward, which can improve the screen-to-body ratio of the display in an electronic device. Therefore, the display panel in the four-curved screen needs to be bent in a direction away from the light-emitting surface. In order to protect the components in the display panel, a UV glue is provided on the light-emitting side of the bent area of the display panel. Before the display panel is bent, the UV glue is set on the light-emitting side of the display panel. The UV glue will abut against the polarizer provided on the light-emitting side of the display panel, and the UV glue will protrude from the polarizer, resulting in stress concentration when the polarizer and the display panel are attached to the cover plate and the display panel is bent, making the display panel prone to cracks. Summary of the Invention
[0003] The present application provides a display device for solving the problem that the display panel is prone to cracks.
[0004] An embodiment of the present application provides a display device. The display device includes:
[0005] A cover plate;
[0006] A display panel, the display panel is connected to the cover plate, and the display panel includes a bent area;
[0007] A polarizer, the polarizer is located between the display panel and the cover plate, and the edge of the polarizer overlaps with the bent area;
[0008] A protective glue, the protective glue is located on the side of the display panel facing the polarizer and overlaps with the bent area. Along the thickness direction of the display device, the protective glue protrudes from the side of the polarizer away from the display panel;
[0009] Wherein, a protective member is provided on the side of the polarizer away from the display panel. Along the thickness direction of the display device, the protective member overlaps with the bent area. The part of the protective glue protruding from the polarizer is connected to the protective member, and the thickness is the same as the thickness of the protective member.
[0010] A protective member is provided on the side of the polarizer away from the display panel, such that the protruding part of the protective adhesive from the polarizer is connected to the protective member and has the same thickness as the protective member. When the display panel is bent, the stress at the protruding position of the protective adhesive can be reduced, the force exerted by the protective adhesive on the corresponding part in the display panel at the protruding position is reduced, and thus the possibility of cracks appearing in the display panel is reduced. When the display panel is bent, it will pull the protective adhesive, causing the protective adhesive to separate from the polarizer. The stress on the position of the display panel corresponding to the separated gap is relatively large, making the display panel prone to cracks. The protective member is provided on the surface of the polarizer and connected to the protective adhesive, which can improve the connection reliability between the protective adhesive and the polarizer, reduce the possibility of the protective adhesive separating from the polarizer when the display panel is bent, and further reduce the possibility of cracks appearing in the display panel.

[0042] As Figure 1 , Figure 2 and Figure 3 shown, the embodiments of the present application provide a display device, including a cover plate 1, a display panel 2, and a polarizer 3. The display panel 2 is connected to one side of the cover plate 1, and the polarizer 3 is located between the display panel 2 and the cover plate 1. The display panel 2 includes a bending region 21, and the edge of the polarizer 3 overlaps with the bending region 21 of the display panel 2. A protective adhesive 4 is further provided on the side of the display panel 2 facing the polarizer 3, and the protective adhesive 4 overlaps with the bending region 21. Along the thickness direction of the display device, the protective adhesive 4 protrudes from the side of the polarizer 3 away from the display panel 2. A protective member 5 is provided on the side of the polarizer 3 away from the display panel 2. Along the thickness direction of the display device, the protective member 5 overlaps with the bending region 21, and the part of the protective adhesive 4 that protrudes from the polarizer 3 is connected to the protective member 5 and has the same thickness as the protective member 5.
[0043] Before connecting the display panel 2 to the cover plate 1, first connect the polarizer 3 to the display panel 2, and a protective adhesive 4 is provided on the side of the display panel 2 facing the polarizer 3. The protective adhesive 4 is connected to the edge of the polarizer 3. To protect the polarizer 3, a protective film is provided on the side of the polarizer 3 away from the display panel 2. The position where the protective adhesive 4 is connected to the polarizer 3 is between the protective film and the display panel 2. When connecting the polarizer 3 and the display panel 2 to the cover plate 1, the protective film needs to be torn off. Due to the siphon phenomenon of the protective film, the edge of the protective adhesive 4 will protrude from the side of the polarizer 3 away from the display panel 2. To increase the screen-to-body ratio of the electronic device equipped with the display device provided by the embodiment of the present application, the edge of the cover plate 1 is bent towards the side where the display panel 2 is provided. When the display panel 2 is connected to the cover plate 1, the bent area 21 of the display panel 2 corresponds to the bent part of the edge of the cover plate 1. The bent area 21 in the display panel 2 is bent away from the cover plate 1, so that the display panel 2 can be attached to the cover plate 1. The bent area 21 includes a folding area 211. The folding area 211 is located in the middle of the bent area 21. The middle part of the protective adhesive 4 overlaps with the folding area 211, and both ends of the protective adhesive 4 protrude from the folding area 211. After the display panel 2 is attached to the cover plate 1, the display panel 2 will be bent in the opposite direction in the folding area 211. The protective adhesive 4 covers the folding area 211 and can protect the components in the folding area 211 of the display panel 2.
[0044] The protective adhesive 4 protrudes from the side of the polarizer 3 away from the display panel 2. When the display panel 2 is attached to the cover plate 1, along the thickness direction of the display device, the stress received by the protruding part is relatively large, so that the acting force of the protective adhesive 4 on the display panel 2 is relatively large, resulting in cracks likely to appear at the position of the display panel 2 corresponding to the protruding part of the protective adhesive 4. A protective member 5 is provided on the side of the polarizer 3 away from the display panel 2, so that the part of the protective adhesive 4 protruding from the polarizer 3 is flush with the surface of the protective member 5 away from the polarizer 3, dispersing the stress of the protruding part of the protective adhesive 4 and reducing the acting force of the protective adhesive 4 on the display panel 2, which is beneficial to reducing the possibility of cracks in the display panel 2. When the folding area 211 in the display panel 2 is bent backward, the display panel 2 will be pulled, resulting in an acting force on the protective adhesive 4 along the direction away from the polarizer 3. If the protective adhesive 4 is separated from the polarizer 3, at the position of the display panel 2 corresponding to the separation area between the protective adhesive 4 and the polarizer 3, the stress generated by folding will increase, making the position of the display panel 2 corresponding to the separation area between the protective adhesive 4 and the polarizer 3 prone to cracks. A protective member 5 is provided on the polarizer 3, and the protective adhesive 4 is connected to the side wall of the protective member 5, increasing the reliability of the connection between the protective adhesive 4 and the polarizer 3 and reducing the possibility of separation between the protective adhesive 4 and the polarizer 3, which is beneficial to reducing the possibility of cracks in the display panel 2.
[0045] In a possible embodiment, the material of the protective glue 4 can be a shadowless glue (also known as UV glue). The UV glue can be quickly cured under the irradiation of ultraviolet light, which is beneficial to improving the production efficiency of the display device. After curing, the UV glue is completely transparent and can remain yellowing-free and whitening-free for a long time, reducing the influence of the protective glue 4 on the display effect. After curing, the UV glue has good flexibility, so the protection effect on the folding area 211 of the display panel 2 is good.
[0046] As Figure 4 shown, in a possible embodiment, along the length direction of the display device, a plurality of recesses 53 are provided on the side of the protector 5 facing the protective glue 4. Along the width direction of the display device, the plurality of recesses 53 are arranged at intervals.
[0047] A plurality of recesses 53 are arranged at intervals on the side wall of the protector 5, making the side wall of the protector 5 wavy. The protective glue 4 can extend into the recesses 53 and connect with the inner walls of the recesses 53, making the connection position between the protective glue 4 and the protector 5 wavy. When the display panel 2 is bent, the connection position between the protector 5 and the protective glue 4 is wavy, which can disperse the stress at the connection position between the protective glue 4 and the protector 5, further reducing the acting force of the protective glue 4 on the display panel 2, and thus reducing the possibility of cracks in the display panel 2. When the display panel 2 is bent, the protective glue 4 is easily separated from the polarizer 3, and cracks are likely to occur in the areas of the display panel 2 corresponding to the positions of the protective glue 4 and the polarizer 3. The recesses 53 are provided on the side wall of the protector 5, and the protective glue 4 is connected with the inner walls of the recesses 53, which can increase the contact area between the protective glue 4 and the protector 5, improve the reliability of the connection between the protective glue 4 and the protector 5. The protector 5 is arranged on the surface of the polarizer 3, thereby improving the reliability of the connection between the protective glue 4 and the polarizer 3, which is beneficial to reducing the possibility of separation between the protective glue 4 and the polarizer 3.
[0048] In a possible embodiment, along the thickness direction of the display device, the projection of the inner wall of the recess 53 on the polarizer can be in the shape of an arc, a triangle, etc., making the edge of the protector 5 wavy or serrated, etc., which can disperse the stress at the connection position between the protective glue 4 and the protector 5, and at the same time can increase the contact area between the protective glue 4 and the protector 5.
[0049] In a possible embodiment, the protective member 5 may include a multi-layer main body portion. Along the thickness direction of the display device, a plurality of main body portions are arranged in sequence, and along the direction away from the polarizer 3, the length of each main body portion gradually decreases. On the side of the protective member 5 facing the protective adhesive 4, the multi-layer main body portions form a multi-layer stepped structure. The portion of the protective adhesive 4 protruding from the polarizer 3 can slope towards the side close to the protective member 5 and cover the stepped structure, reducing the thickness of the portion of the protective adhesive 4 protruding from the polarizer 3. At the same time, the stress on the portion of the protective adhesive 4 protruding from the polarizer 3 is also reduced, thereby reducing the acting force of the protective adhesive 4 on the display panel 2, which is beneficial to reducing the possibility of cracks in the display panel 2.
[0050] As Figure 5 shown, in a possible embodiment, the protective member 5 includes a first main body portion 51 and a second main body portion 52. Along the direction away from the polarizer 3, the first main body portion 51 and the second main body portion 52 are arranged in sequence. Along the length direction of the display device, on the side of the protective member 5 close to the protective adhesive 4, the first main body portion 51 protrudes from the second main body portion 52.
[0051] The first main body portion 51 protrudes from the second main body portion 52, forming a step on the side of the protective member 5 close to the protective adhesive 4. The portion of the protective adhesive 4 protruding from the polarizer 3 will start to slope from the edge of the first main body portion 51 and flow towards the side wall close to the second main body portion 52, so that the side walls of both the first main body portion 51 and the second main body portion 52 are connected to the protective adhesive 4.
[0052] A step is provided on the side of the protective member 5 close to the protective adhesive 4, causing the portion of the protective adhesive 4 protruding from the polarizer 3 to flow towards the side close to the protective member 5, reducing the height of the portion of the protective adhesive 4 protruding from the polarizer 3. When bending, the stress concentrated on the protruding portion is reduced. At the same time, the protective adhesive 4 is respectively connected to the side wall of the first main body portion 51 and the side wall of the second main body portion 52. When the display panel 2 is bent, the stress received at the edge of the protective adhesive 4 can be dispersed to the two connection surfaces, reducing the possibility that the acting force of the protective adhesive 4 on the display panel 2 is concentrated at the same position, which is beneficial to reducing the possibility of cracks in the display panel 2.
[0053] As Figure 5 and Figure 6 shown, in a possible embodiment, the protective adhesive 4 covers the portion where the first main body portion 51 protrudes from the second main body portion 52 and is connected to the side wall of the second main body portion 52. Along the thickness direction of the display device, the protective adhesive 4 is flush with the side of the second main body portion 52 away from the first main body portion 51.
[0054] During the process of the part of the protective glue 4 protruding from the polarizer 3 flowing towards the side wall close to the second main body part 52, the protective glue 4 will cover the part of the first main body part 51 protruding from the second main body part 52. The side wall of the second main body part 52 will block the protective glue 4 from continuing to flow in the original direction, causing the protective glue 4 to accumulate at the side wall of the second main body part 52. The length of the part of the first main body part 51 protruding from the second main body part 52, the thickness of the first main body part 51, and the thickness of the second main body part 52 can all be adjusted according to the volume or height of the part of the protective glue 4 protruding from the polarizer 3, so that the upper surface of the protective glue 4 accumulated at the side wall of the second main body part 52 is flush with the surface of the second main body part 52 away from the first main body part 51.
[0055] The protective glue 4 covering the part of the first main body part 51 protruding from the second main body part 52 increases the contact area between the protective glue 4 and the protective part 5, and further reduces the possibility of the protective glue 4 separating from the polarizer 3. If the protective glue 4 protrudes from the side of the second main body part 52 away from the first main body part 51, when the display panel 2 is bent, the part of the protective glue 4 protruding from the second main body part 52 is subjected to greater stress. If the protective glue 4 is lower than the side of the second main body part 52 away from the first main body part 51, when the display panel 2 is bent, the part of the second main body part 52 is subjected to greater stress. The protective glue 4 is flush with the side of the second main body part 52 away from the first main body part 51, enabling the protective part 5 to disperse the stress of the part of the protective glue 4 protruding from the polarizer 3, reducing the acting force of the protective glue 4 on the display panel 2, and at the same time, it can also reduce the stress on the side wall of the second main body part 52, reducing the acting force of the protective part 5 on the polarizer 3.
[0056] As Figure 7 、 Figure 8 and Figure 9 shown, in a possible embodiment, along the length direction of the display device, a plurality of recessed parts 53 are provided on the side of the first main body part 51 facing the protective glue 4 and / or on the side of the second main body part 52 facing the protective glue 4. Along the width direction of the display device, the plurality of recessed parts 53 are arranged at intervals.
[0057] The plurality of recessed parts 53 are arranged at intervals, and the first main body part 51 and / or the second main body part 52 form a wavy side wall. The protective glue 4 can extend into the recessed parts 53 and be connected to the inner walls of the recessed parts 53, so that the surface of the protective glue 4 connected to the first main body part 51 and / or the second main body part 52 is wavy.
[0058] The surface of the protective adhesive 4 connected to the first main body portion 51 is wavy. When the display panel 2 is bent, it can disperse the stress at the connection between the protective adhesive 4 and the first main body portion 51, further reducing the force exerted by the protective adhesive 4 on the display panel, and thus reducing the possibility of cracks in the display panel 2. The surface of the protective adhesive 4 connected to the second main body portion 52 is wavy. When the display panel 2 is bent, it can disperse the stress at the connection between the protective adhesive 4 and the second main body portion 52, reducing the force exerted by the protective adhesive 4 and the second main body portion 52 on the first main body portion 51, and further reducing the force on the polarizer 3 and the display panel 2. At the same time, the wavy side wall can increase the contact area between the protective adhesive 4 and the first main body portion 51 and / or the second main body portion 52, which is beneficial to improving the connection reliability between the protective adhesive 4 and the protective member 5. The protective member 5 is connected to the polarizer 3, thereby reducing the possibility that the protective adhesive 4 is separated from the polarizer 3, and the stress at the position corresponding to the separation area of the display panel 2 from the protective adhesive 4 and the polarizer 3 is large, resulting in cracks.
[0059] In a possible embodiment, the thicknesses of both the first main body portion 51 and the second main body portion 52 are 8 mm to 10 mm.
[0060] The thickness of the first main body portion 51 can be 8 mm, 9 mm, 10 mm, etc., and the thickness of the second main body portion 52 can also be 8 mm, 9 mm, 10 mm, etc. At the same time, the thicknesses of the first main body portion 51 and the second main body portion 52 can be inconsistent. The thicknesses of the first main body portion 51 and the second main body portion 52 can be adjusted according to the thickness or volume of the part of the protective adhesive 4 protruding from the polarizer 3, so that the protective adhesive 4 can cover the part of the first main body portion 51 protruding from the second main body portion 52, and the upper surface of the protective adhesive 4 is flush with the surface of the second main body portion 52 away from the first main body portion 51.
[0061] As Figure 5 and Figure 6 shown, in a possible embodiment, along the length direction of the display device, the side wall of the first main body portion 51 facing the protective adhesive 4 is flush with the side wall of the polarizer 3.
[0062] The display panel 2 includes a light-emitting side and a backlight side. The cover plate 1, the polarizer 3, and the protective adhesive 4 are all located on the light-emitting side of the display panel 2. The polarizer 3 is located between the display panel 2 and the cover plate 1, and the edge of the polarizer 3 is located in the bending area 21 of the display panel 2 and will bend with the display panel 2. The bent part of the edge of the polarizer 3 will reflect the light transmitted by the cover plate 1. Therefore, on the light-emitting side of the display device, a white edge strip can be seen due to the reflection of the edge of the polarizer 3, which affects the display effect of the display device. The protective member 5 is located on the side of the polarizer 3 away from the display panel 2 and is flush with the side wall of the polarizer 3, which can block the edge of the polarizer 3 and is beneficial to improving the display effect of the display device.
[0063] In a possible embodiment, the material of the protection member 5 is ink.
[0064] The ink has a low light transmittance, which can improve the shielding effect on the edge of the polarizer 3, and further improve the display effect of the display device. At the same time, the ink printing process is relatively mature, which is convenient to control the position, shape and thickness of the first main body part 51 and the second main body part 52, and is beneficial to improving the position accuracy and printing efficiency of the protection member 5.
[0065] As Figure 1 shown, in a possible embodiment, an adhesive member 6 is provided between the polarizer 3 and the cover plate 1, and along the thickness direction of the display device, the adhesive member 6 overlaps with the polarizer 3 and the protection member 5.
[0066] The adhesive member 6 is used to connect the polarizer 3 and the cover plate 1. The adhesive member 6 can be an optically clear adhesive (OCA). The optically clear adhesive has the characteristics of being colorless, having a light transmittance of more than 95%, good bonding strength, being curable at room temperature, and having small curing shrinkage. The adhesive member 6 overlaps with the polarizer 3 and the protection member 5, and can bond the polarizer 3 and the protection member 5 to the cover plate 1. The light emitted from the display panel 2 can also pass through the optically clear adhesive, so that the display effect of the display device is better.
[0067] As Figure 5 shown, in a possible embodiment, along the length direction of the display device, on the side of the protection member 5 away from the protective glue 4, the first main body part 51 protrudes from the second main body part 52.
[0068] An adhesive member 6 is provided on the side of the polarizer 3 away from the display panel 2, and the adhesive member 6 overlaps with the polarizer 3 and the protection member 5. The side of the protection member 5 away from the protective glue 4 is connected to the adhesive member 6. If the first main body part 51 and the second main body part 52 are flush on the side of the protection member 5 connected to the adhesive member, the side wall thickness of the protection member 5 connected to the adhesive member 6 is relatively large, which makes it easy to generate air bubbles at the connection position between the adhesive member 6 and the protection member 5, affecting the display effect of the display device.
[0069] The first main body part 51 protrudes from the second main body part 52, so that the adhesive member 6 is respectively connected to the side wall of the first main body part 51 and the side wall of the second main body part 52. Compared with the protection member 5, the side wall thickness of the first main body part 51 and the side wall of the second main body part 52 is relatively small, reducing the possibility of generating air bubbles in the adhesive member 6, which is beneficial to improving the display effect of the display device.
[0070] As Figure 1As shown, in a possible embodiment, a support member 7 is provided on the side of the display panel 2 away from the polarizer 3. Along the length direction of the display panel 2, the support members 7 are located at both ends of the folding area 211. After the folding area 211 is folded, the two support members 7 at both ends of the folding area 211 are approximately parallel. The support member 7 is used to support the display panel 2, reducing the possibility of deformation of the display panel 2 and facilitating the improvement of the reliability of the display device.
[0071] As Figure 1 shown, in a possible embodiment, a filling member 8 is provided on the side of the display panel 2 away from the polarizer 3. After the folding area 211 of the display panel 2 is folded, the display panel has a U-shaped structure, and both ends of the folding area 211 are approximately parallel. The filling member 8 is located between the two support members 7 and is used to limit the distance between the two support members 7, thereby limiting the folding angle of the folding area 211 and facilitating the improvement of the stability of the display panel 2.
[0072] An embodiment of the present application provides a display device, including a cover plate 1, a display panel 2, a polarizer 3, and a protective adhesive 4. The display panel 2 is located on one side of the cover plate 1, the polarizer 3 is located between the cover plate 1 and the display panel 2, and the protective adhesive 4 is located on the side of the display panel 2 facing the polarizer 3. The display panel 2 includes a bending area 21. Along the thickness direction of the display device, the edges of the polarizer 3 and the protective adhesive 4 both overlap with the bending area 21, and the protective adhesive 4 protrudes from the side of the polarizer 3 away from the display panel 2. A protective member 5 is provided on the side of the polarizer 3 away from the display panel 2. The part of the protective adhesive 4 that protrudes from the polarizer 3 is connected to the protective member 5 and has the same thickness as the protective member 5. When the bending area 21 of the display panel 2 is bent, the protective member 5 can reduce the stress of the part of the protective adhesive 4 that protrudes from the polarizer 3, thereby reducing the possibility of the protective adhesive 4 pressing the display panel 2 to cause cracks. At the same time, it can reduce the possibility of the protective adhesive 4 separating from the polarizer 3, thereby reducing the possibility of cracks occurring at the position where the stress of the display panel 2 is concentrated at the separation of the protective adhesive 4 and the polarizer 3.
