Referring to
a display panel 100 including a support layer 110 and a panel body 120 disposed on the support layer 110;
an encapsulation protection assembly 200 including a protection layer 210 and a frame 220, wherein the frame 220 is disposed on one side of the support layer 110 away from the panel body 120, and the protection layer 210 is disposed on one side of the panel body 120 away from the support layer 110. Edges of the protection layer 210 surround a periphery of the display panel 100, extend to one side of the support layer 110 away from the panel body 120, and are connected to the frame 220.
It can be understood that, at present, signal lines such as gate signal lines, voltage signal lines, driving signal lines are disposed at edges of an organic light-emitting diode (OLED) display device. Usually, edges of the OLED display device are more likely to be damaged by external impact or scratching, especially in a flexible or foldable OLED display device. Therefore, a front frame structure is usually used to protect the OLED display device. However, when the front frame structure is assembled with the OLED display device, it occupies a certain space at the edges of the display device, which reduces a screen ratio and affects an overall visual experience provided by the display device. In the present embodiment, the protection layer 210 is disposed on the side of the panel body 120 away from the support layer 110. The edges of the protection layer 210 surround a periphery of the display panel 100, extend to one side of the support layer 110 away from the panel body 120, and are connected to the frame 220. As a result, the present application realizes encapsulation and provides protection for surfaces and the periphery of the panel body 120 without reducing a screen ratio of the display device.
It should be noted that, in the encapsulation protection assembly 200, the protection layer 210 is disposed on one side of the panel body 120 away from the support layer 110. That is to say, the protection layer 210 is used to protect a light emitting side of the panel body 120. The frame 220 is disposed at one side of the support layer 110 away from the panel body 120 and is used for connecting a connection sub-portion 2122 of the edge protection portion 212 without affecting the screen ratio of the display device. Accordingly, the present application ensures the support rigidity of the edge protection portion 212 encapsulating the periphery of the panel body 120. In the present embodiment, the connection sub-portion 2122 of the edge protection portion 212 can be fixedly connected to the frame 220 by means of thermoplastic molding or adhesive bonding. The protection layer 210 not only has better resistance to scratch and anti-wear properties, but also has high light transmittance. Specifically, the protection layer 210 can be made of one of flexible ultra-thin glass (UTG), colorless Polyimide (CPI), polyethylene terepthalate (PET). The frame 220 can be formed by a press forming process. A material of the frame 220 can include at least one of titanium alloy, magnesium alloy, and aluminum alloy.
It should be noted that, in the present embodiment, the display panel 100 can be a non-flexible display panel that cannot be bent, and the encapsulation protection assembly 200 can be used to encapsulate and protect the surface and side edges of the non-flexible display panel 100. Certainly, the encapsulation protection assembly 200 can also be used to encapsulate and protect a bendable or foldable flexible display panel 100. No matter whether the display panel 100 is a non-flexible display panel 100 or a flexible display panel 100, the encapsulation protection assembly 200 is connected to the display panel 100 through at least the main protection portion 211, so as to achieve encapsulation and provide protection for the surface and the periphery of the display panel 100 by using the encapsulation protection assembly 200.
In one embodiment, as shown in
The encapsulation protection assembly 200 is connected to the display panel 100 at least through the main protection portion 211.
It can be understood that by the protection layer 210 is divided into the main protection portion 211, disposed on one side of the panel body 120 away from the support layer 110, and an edge protection portion 212 disposed at a periphery of the main protection portion 211. In addition, the edge protection portion 212 includes the lateral side protection sub-portion 2121 disposed around the periphery of the display panel 100, and includes the connection sub-portion 2122 extending from one side of the lateral side protection sub-portion 2121 away from the main protection portion 211 to one side of the support layer 110 facing away from the panel body 120. The frame 220 is connected to the connection sub-portion 2122 and is located at one side of the support layer 110 away from the panel body 120. Accordingly, the present application can encapsulate and protect the surface and the periphery of the panel body 120 without affecting the screen ratio of the display device. At the same time, the frame 220 and the connection sub-portion 2122 are connected at one side of the support layer 110 away from the panel body 120, so the present application can ensure support rigidity of the edge protection portion 212 encapsulating the periphery of the panel body 120.
In one embodiment, the frame 220 is disposed between the connection sub-portion 2122 and the support layer 110. One side of the frame 220 is connected to the support layer 110, and another side of the frame 220 is connected to the connection sub-section 2122. It can be understood that when the display panel 100 is a non-flexible display panel 100, the support layer 110 can be directly and fixedly connected to the support layer 110, and the support layer 110 and the protection layer 210 can be integrated by means of the frame 220 to provide all-round encapsulation and protection for the panel body 120.
In one embodiment, please refer to
The frame 220 is spaced apart from the display panel 100, and the frame 220 includes a first opening 221 corresponding to the bending display portion 130.
The edge protection portion 212 is spaced apart from the display panel 100, and the edge protection portion 212 includes a second opening 2123 corresponding to the bending display portion 130.
It can be understood that when the display panel 100 is a flexible display panel, the display panel 100 includes the bending display portion 130, the display panel 100 can be bent at a position of the bending display portion 130, the frame 220 includes the first opening 221 at a position corresponding to the bending display portion 130, and the edge protection portion 212 includes the second opening 2123 at a position corresponding to the bending display portion 130. The frame 220 and the edge protection portion 212 are disconnected at a position corresponding to the bending display portion 130, so as to prevent the frame 220 or the edge protection portion 212 from interfering with the display panel 100 during a bending process of the display panel 100. In addition, the frame 220 is spaced apart from the display panel 100, and the edge protection portion 212 is spaced apart from the display panel 100. Obviously, the encapsulation protection assembly 200 is connected to the display panel 100 through only the main protection portion 211. The frame 220 and the display panel 100 are spaced apart, and the edge protection portion 212 and the display panel 100 are also spaced apart, so the present application prevents the frame 220 or the edge protection portion 212 from being affected by the display panel to cause the main protection portion 211 from peeling off from the display panel 100 during the bending process of the display panel 100.
It should be noted that the frame 220 includes the first opening 221 at a position corresponding to the bending display portion 130, and the edge protection portion 212 includes the second opening 2123 at a position corresponding to the bending display portion 130. On the premise that the frame 220 and the edge protection portion 212 do not affect the bending of the display panel 100, sizes of the first opening 221 and the second opening 2123 do not have a particular limitation.
In this embodiment, as shown in
Please refer to
each corner protection section 2126 is disposed between one of the first protection sections 2124 and one of the second protection sections 2125, and the corner protection section 2126 is spaced apart from the first protection section 2124 and the second protection section 2125;
the first protection section 2124 extends along the first direction 10, the bending display portion 130 includes a bending axis extending along the second direction 20, and a predetermined angle is included between the second direction 20 and the first direction 10. The second opening 2123 includes two sub-openings 21231 corresponding to the bending display portion 130, and the two sub-openings 21231 are defined in the two first protection sections 2124, respectively.
It can be understood that different functional film layers such as the support layer 110, the flexible substrate 121, the display functional layer 122, and the polarizer 123 undergo shifting and deformation during the bending process of the display panel 100, resulting in replacement between the different film layers. The edge protection portion 212 is configured to include two first protection sections 2124 respectively located on opposite side edges of the display panel 100 and two second protection sections 2125 respectively located at opposite ends of the display panel 100, and multiple corner protection sections 2126 respectively located at corners of the display panel 100. Furthermore, the corner protection sections 2126 are spaced apart from the first protection sections 2124 and the second protection sections 2125. Such configurations provide sufficient space for the shifting and deformation of the functional film layers during the bending process of the display panel 100. This way, the present application prevents the shifting and deformation of the functional film layers from interfering with the edge protection portion 212 and causing the main protection portion 211 to be peeled off from the display panel 100. Each corner protection section 2126 can be in the shape of a circular arc at a viewing angle perpendicular to the display panel 100, and the corner protection section 2126 can be used for the transition between the first protection section 2124 and the second protection section 2125, so as to encapsulate and protect the corner of the display panel 100.
It should be noted that the first protection section 2124 extends along the first direction 10, the bending display portion 130 includes the bending axis extending along the second direction 20, and a predetermined angle is included between the second direction 20 and the first direction 10. The second opening 2123 includes two sub-openings 21231 corresponding to the bending display portion 130, and the two sub-openings 21231 are defined in the two first protection sections 2124, respectively. In the present embodiment, a length of the first protection section 2124 is greater than a length of the second protection section 2125, and the sub-opening 21231 divides, at a position corresponding to the bending display portion 130, the first protection section 2124 into two parts. The included angle between the first direction 10 and the second direction 20 can be set to 90 degrees.
In one embodiment, please refer to
When the display panel 100 is in a bent state, at a side edge of the flat display portion 140 away from the bending display portion 130, a displacement distance from an end surface of the support layer 110 to a plane where an end surface of the main protection portion 211 is located is less than or equal to a predetermined distance a, and a distance between the first protection section 2124 and the corner protection section 2126 is greater than the predetermined distance a.
It can be understood that the display panel 100 can include a flat state and a bent state. When the display panel 100 is in a bent state, the display panel 100 is bent about the bending axis. At this point, different functional film layers such as the support layer 110, the flexible substrate 121, the display functional layer 122, and the polarizer 123 shift and deform during the bending process of the display panel 100, resulting in certain displacement between the different film layers. Obviously, compared with other functional film layers, the displacement distance between the support layer 110 and the main protection portion 211 which are located on opposite sides of the panel body 120 is relatively large. As shown in
In one embodiment, please refer to
In the two flat display portions 140, a flexible circuit board 150 is disposed at one end of one of the flat display portions 140 away from the bending display portion 130.

In the two sub-frames 222, one of the sub-frames 222 close to the flexible circuit board 150 is provided with a clearance opening 2221 at a position corresponding to the flexible circuit board 150.
It can be understood that, in the two flat display portions 140, one end of one of the flat display portions 140 away from the bending display portion 130 is provided with the flexible circuit board 150. Obviously, by bending a bonding terminal, the flexible circuit board 150 is bonded to one side of the flat display portion 140 away from the main protection portion 211. In the two sub-frames 222, one of the sub-frames 222 close to the flexible circuit board 150 is provided with the clearance opening 2221 at the position corresponding to the flexible circuit board 150. The clearance opening 2221 provides sufficient space for the bending and bonding of the flexible circuit board 150.

The clearance opening 2221 is defined in the sub-frame 222 at the position corresponding to the flexible circuit board 150. Under the premise of avoiding interference between the sub-frame 222 and the flexible circuit board 150, the size of the clearance opening 2221 do not have specific limitations.

In one embodiment, as shown in
It can be understood that the frame body 320 further includes the side frame portion 323 located on one side of the lateral side protection sub-portion 2121 away from the display panel 100.

Furthermore, the accommodating groove 322 is located between the connecting protrusion 321 and the side frame portion 323, and the lateral side protection sub-portion 2121 and the side frame portion 323 are spaced apart. Under the condition that the side frame portion 323 protects the periphery of the display panel 100, the lateral side protection sub-portion 2121 and the side frame portion 323 are arranged spaced apart, which also prevents the frame body 320 and the sub-frame 222 from interfering with each other to cause the main protection portion 211 to be peeled off from the display panel 100 during the bending process of the display device.
