Description

Technical Field

[0001] The present application relates to the field of display technologies, and particularly to a display panel and a display device. Background Art

[0002] OLED (Organic Light-Emitting Diode) display panels have characteristics such as self-luminescence, no need for a backlight module, high contrast, and high clarity, and thus are increasingly widely used in terminal products that require lightness, thinness, and portability, such as mobile phones, tablets, and laptop computers. Since OLED devices are very sensitive to moisture and oxygen, OLED devices are mostly encapsulated with a packaging structure to block moisture and oxygen. The commonly used packaging for OLEDs is in the form of Frit packaging. Specifically, glass frit is printed at a preset position on the packaging glass cover plate, and a laser beam is used to move and heat the glass frit to melt it, thereby forming an airtight Frit packaging layer between the packaging glass cover plate and the substrate. The Frit packaging layer surrounds the outside of the OLED light-emitting device.

[0003] However, since there is no support structure in the interval area between the inner side of the Frit packaging layer and the outside of the OLED light-emitting device, when the display panel drops, the part of the display panel corresponding to this interval area is easily subjected to an inward stress from the outside and breaks. Summary of the Invention

[0004] Based on this, it is necessary to provide a display panel and a display device to improve the anti-drop and anti-compression capabilities of the display panel.

[0005] According to one aspect of the present application, a display panel is provided, including:

[0006] A substrate having a display area and a border area disposed around the display area;

[0007] A packaging cover plate disposed opposite to the substrate;

[0008] A packaging layer disposed between the substrate and the packaging cover plate; and

[0009] An anti-drop component including a first magnetic layer disposed on the side of the packaging cover plate facing away from the substrate, and a second magnetic layer disposed on the side of the substrate facing away from the packaging cover plate; wherein, the orthographic projection of the packaging layer on the substrate surrounds the display area and has an interval area between it and the display area;

[0010] The magnetic pole surfaces of the first magnetic layer and the second magnetic layer with the same polarity face each other, and the orthographic projections of the first magnetic layer and the second magnetic layer on the substrate have an overlapping area, and at least part of the overlapping area is located in the interval area.

[0011] In the related art, since there is no support structure in the spacer region between the encapsulation layer and the display region, when the display panel drops, the portion of the display panel corresponding to this spacer region is vulnerable to the inward stress from the outside and crack. In the above solution of the present application, by providing a fall prevention component, a first magnetic layer is provided on the side of the encapsulation cover plate facing away from the substrate, and a second magnetic layer is provided on the side of the substrate facing away from the encapsulation cover plate, and the magnetic pole surfaces of the first magnetic layer and the second magnetic layer with the same polarity face each other. Thus, in the first magnetic layer and the second magnetic layer, the regions facing each other, that is, the regions whose orthographic projections on the substrate have overlapping portions, will generate repulsive forces against each other. And at least part of this overlapping portion is located within the spacer region, that is, the action range of the above-mentioned repulsive forces against each other is located on the portions of the encapsulation cover plate and the substrate corresponding to this spacer region. In other words, in the portions of the encapsulation cover plate and the substrate corresponding to this spacer region, the first magnetic layer and the encapsulation cover plate will be subject to the repulsive force away from the substrate applied by the second magnetic layer, and the second magnetic layer and the substrate will be subject to the repulsive force away from the encapsulation cover plate applied by the first magnetic layer. When the display panel drops or the like, this repulsive force can at least partially offset the stress received at the position of the display panel corresponding to this spacer region, reduce the degree of crack occurrence, and prevent the display panel from cracking.

[0012] In some embodiments, both the first magnetic layer and the second magnetic layer are electromagnet layers; the first magnetic layer and the second magnetic layer are configured to generate repulsive forces when powered on.

[0013] When the first magnetic layer and the second magnetic layer are electromagnetic layers, they generate magnetism only when powered on, which can avoid the possible adverse effects of the first magnetic layer and the second magnetic layer on the display of the display panel.

[0014] In some embodiments, the display panel further includes:

[0015] an acceleration sensor for detecting the acceleration information of the display panel;

[0016] a controller electrically connected to the acceleration sensor, the first magnetic layer, and the second magnetic layer respectively;

[0017] The controller is configured to determine whether the display panel is in a weightless state according to the acceleration information detected by the acceleration sensor, and control the first magnetic layer and the second magnetic layer to be powered on when it is determined that the display panel is in a weightless state.

[0018] Thus, the controller obtains the state of the display panel through the acceleration sensor. When it is determined that the display panel is in a weightless state such as falling, the first magnetic layer and the second magnetic layer are turned on, and repulsive forces are generated. In this way, when the display panel is in a weightless state, the first magnetic layer and the second magnetic layer are powered on, while when the display panel is in a normal use state, the first magnetic layer and the second magnetic layer are not powered on and do not generate magnetism.

[0019] Preferably, the controller is configured to determine that the display panel is in a weightless state when the acceleration information detected by the acceleration sensor is greater than a preset threshold.

[0020] In some embodiments, the first magnetic layer and the second magnetic layer are permanent magnetic layers. In this way, the display panel can be better protected when it is collided or extruded by an external force.

[0021] Preferably, the repulsive force between the first magnetic layer and the second magnetic layer is less than the adhesive force between the encapsulation cover plate and the substrate and the encapsulation layer. This can prevent the encapsulation cover plate and the substrate from being peeled off from the encapsulation layer respectively.

[0022] In some embodiments, the projection of the first magnetic layer on the substrate is located in the border area;

[0023] Preferably, a polarizer is provided on the surface of the encapsulation cover plate facing away from the substrate, and the orthographic projection of the polarizer on the substrate covers the display area; the first magnetic layer is arranged around the polarizer;

[0024] In this way, the first magnetic layer is formed into an annular structure, which can protect the spacer area within the entire circumference. The first magnetic layer surrounding the circumferential outer side of the polarizer can also avoid affecting the display area covered by the polarizer.

[0025] Preferably, the edge of the orthographic projection of the polarizer on the substrate is located in the spacer area; the inner edge of the first magnetic layer is adjacent to the outer edge of the polarizer.

[0026] In this way, the polarizer can cover the display area of the display panel as much as possible to avoid light leakage. And the area of the first magnetic layer above the spacer area is increased as much as possible.

[0027] In some embodiments, the projection of the second magnetic layer on the substrate is located in the border area; a support layer is provided on the surface of the substrate facing away from the encapsulation cover plate, and the second magnetic layer is arranged around the support layer. In this way, the second magnetic layer is also formed into an annular structure, which can protect the spacer area within the entire circumference.

[0028] In some embodiments, the inner edge of the orthographic projection of the second magnetic layer on the substrate completely coincides with the inner edge of the orthographic projection of the first magnetic layer on the substrate; and / or the outer edge of the orthographic projection of the second magnetic layer on the substrate completely coincides with the outer edge of the orthographic projection of the first magnetic layer on the substrate. In this way, the first magnetic layer and the second magnetic layer can be arranged opposite to each other in the thickness direction D.

[0029] In some embodiments, the second magnetic layer entirely covers the surface of the substrate facing away from the encapsulation cover plate, and a support layer is further provided on the surface of the second magnetic layer facing away from the substrate. In this way, the second magnetic layer can play an auxiliary supporting role for the display panel, and the design flexibility of the position of the first magnetic layer is also relatively high.

[0030] In some embodiments, the first magnetic layer is bonded to the encapsulation cover plate by an adhesive; and / or the second magnetic layer is bonded to the substrate by an adhesive. By bonding with an adhesive as described above, the first magnetic layer and the encapsulation cover plate can have good bonding properties. In this way, when the first magnetic layer is subjected to the repulsive force of the second magnetic layer, the repulsive force can be transmitted to the encapsulation cover plate. Similarly, the second magnetic layer and the substrate can have good bonding properties, so that when the second magnetic layer is subjected to the repulsive force of the first magnetic layer, the repulsive force can be transmitted to the substrate.

[0031] According to another aspect of the present application, there is also provided a display device including the above-mentioned display panel. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] With the development of technologies such as big data, cloud computing, and mobile Internet, humans have entered the intelligent era. Intelligent devices including intelligent mobile communication terminals, wearable devices, and smart homes have become an indispensable part of people's work and life. As an important window for human-computer interaction in the intelligent era, display panels are also undergoing major changes. Organic Light-Emitting Diode (OLED) display panels, which have advantages such as thin thickness, self-luminous performance, low power consumption, and good flexibility, have become the most promising display devices after thin-film transistor liquid crystal displays.

[0045] In an OLED display panel, the OLED device is very sensitive to water vapor and oxygen. Therefore, the OLED device is mostly encapsulated with a packaging structure to block water vapor and oxygen. The common packaging of OLEDs is in the form of thin-film packaging or glass frit (Frit) packaging. Usually, an OLED display panel includes a packaging glass cover plate, a substrate, and an OLED light-emitting device sandwiched between the packaging glass cover plate and the substrate. During packaging, first, the glass frit is printed at a preset position on the packaging glass cover plate, and a laser beam is used to move and heat the glass frit to melt it, so as to form an airtight Frit packaging layer between the packaging glass cover plate and the substrate. The Frit packaging layer surrounds the outside of the OLED light-emitting device and there is a spaced area between the Frit packaging layer and the OLED light-emitting device.

[0046] However, in the current OLED display panel using Frit packaging, there is no support structure in the spaced area between the Frit packaging layer and the OLED light-emitting device. When the OLED display panel drops, etc., the position of the OLED display panel corresponding to the spaced area is prone to cracking due to stress concentration, seriously affecting the service life of the display device.

[0047] In view of the above problems, the embodiments of the present application propose a display panel and a display device, by setting a first magnetic layer and a second magnetic layer capable of generating repulsive forces at positions corresponding to the inner side of the packaging layer on the display panel, reducing the stress concentration at the positions corresponding to the inner side of the packaging layer on the display panel, and preventing the display panel from cracking.

[0048] Figure 1 It is a schematic cross-sectional structure diagram of a display panel provided by an embodiment of the present application. Figure 2 It is a top view of a display panel provided by an embodiment of the present application.

[0049] Referring to Figure 1 、 Figure 2 , on the one hand, an embodiment of the present application provides a display panel 100, including a substrate 10, a packaging cover plate 20, a packaging layer 40, and an anti-drop component 42.

[0050] The substrate 10 has a display area A and a border area provided around the display area A. The packaging cover plate 20 is disposed opposite to the substrate 10; the packaging layer 40 is disposed between the substrate 10 and the packaging cover plate 20. The anti-drop component 42 includes a first magnetic layer 50 disposed on the side of the packaging cover plate 20 facing away from the substrate 10, and a second magnetic layer 60 disposed on the side of the substrate 10 facing away from the packaging cover plate 20; wherein, the orthographic projection of the packaging layer 40 on the substrate 10 surrounds the display area A, and there is a spaced area 41 between the packaging layer 40 and the display area A.

[0051] The magnetic pole faces of the first magnetic layer 50 and the second magnetic layer 60 with the same polarity face each other, and the orthographic projections of the first magnetic layer 50 and the second magnetic layer 60 on the substrate 10 have an overlapping area, and at least part of the overlapping area is located in the spacer area 41.

[0052] It should be noted that the display area A ( Figure 1 the area within the dashed box in ) of the substrate 10 refers to the area on the substrate 10 corresponding to the OLED light-emitting device 30. The OLED light-emitting device 30 is located between the substrate 10 and the encapsulation cover plate 20.

[0053] In the related art, since there is no support structure in the spacer area 41 between the encapsulation layer 40 and the display area A, when the display panel 100 drops, the part of the display panel 100 corresponding to this spacer area 41 is prone to crack due to the inward stress from the outside. In the embodiment of the present application, by providing a fall prevention component 42, the fall prevention component 42 includes a first magnetic layer 50 and a second magnetic layer 60. The first magnetic layer 50 is provided on the side of the encapsulation cover plate 20 facing away from the substrate 10, and the second magnetic layer 60 is provided on the side of the substrate 10 facing away from the encapsulation cover plate 20, and the magnetic pole faces of the first magnetic layer 50 and the second magnetic layer 60 with the same polarity face each other. Thus, in the first magnetic layer 50 and the second magnetic layer 60, the areas facing each other, that is, the areas having an overlapping part in the orthographic projection on the substrate 10, will generate repulsive forces against each other. And at least part of this overlapping part is located within the spacer area 41, that is, the acting range of the above-mentioned repulsive forces against each other is located between the encapsulation cover plate 20 and the part of the substrate 10 corresponding to this spacer area 41. In other words, in the part of the encapsulation cover plate 20 and the substrate 10 corresponding to this spacer area 41, the first magnetic layer 50 and the encapsulation cover plate 20 will be subjected to a repulsive force away from the substrate 10 applied by the second magnetic layer 60, and the second magnetic layer 60 and the substrate 10 will be subjected to a repulsive force away from the encapsulation cover plate 20 applied by the first magnetic layer 50. When the display panel 100 drops or the like, this repulsive force can at least partially offset the stress received at the position of the display panel 100 corresponding to this spacer area 41, reduce the degree of crack occurrence, and prevent the display panel 100 from cracking.

[0054] In addition, combined with Figure 1 、 Figure 2, it can be understood that in order to block the influence of oxygen and water vapor on the OLED light-emitting device 30, an encapsulation layer 40 for encapsulating the OLED light-emitting device 30 is provided around the display area A of the substrate 10, that is, on the outer side of the OLED light-emitting device 30. Exemplarily, the formation process of the encapsulation layer 40 is as follows: Printing frit on the encapsulation cover plate 20 and using a laser beam to move and heat the frit to melt the frit to form the encapsulation layer 40 on the substrate 10. One end of the thus formed encapsulation layer 40 is connected to the encapsulation cover plate 20, and the other end is connected to the border area of the substrate 10. And a spacing area 41 is formed between the projection of the encapsulation layer 40 on the substrate 10 and the display area A. Cracks and ruptures on the display panel 100 are likely to occur at positions corresponding to this spacing area 41. To facilitate the description of the relative positions of the first magnetic layer 50 and the second magnetic layer 60 with respect to this spacing area 41, here, the first magnetic layer 50 and the second magnetic layer 60 are also projected onto the substrate 10, in combination with Figure 1 , Figure 2 As shown, a spacing area 41 is defined between the projection of the encapsulation layer 40 on the substrate 10 and the display area A. The smaller dashed frame is the outer edge X of the display area A, and the larger dashed frame is the inner edge Y of the projection of the encapsulation layer 40 on the substrate 10. The outer edge X and the inner edge Y jointly define the above-mentioned spacing area 41.

[0055] The projections of the first magnetic layer 50 and the second magnetic layer 60 on the substrate 10 have an overlapping part, and the overlapping part is at least partially located within the spacing area 41. In other words, the first magnetic layer 50 and the second magnetic layer 60 have facing parts in the thickness direction D of the display substrate 10, and at least part of the structure of the facing parts is located on the upper and lower sides of the spacing area 41. In this way, a repulsive force can be generated between the facing parts of the first magnetic layer 50 and the second magnetic layer 60 in the thickness direction D, so that the encapsulation cover plate 20 and the substrate 10 connected to the facing parts are also subjected to a repulsive force towards the outside of the display panel 100.

[0056] In the embodiment of the present application, the substrate 10 may include a glass substrate and a thin film transistor (Thin Film Transistor, TFT) driving board. The TFT driving board is formed on the glass substrate and is used to drive each pixel of the OLED light-emitting device 30. The TFT driving board may be a low temperature polysilicon TFT (Low Temperature Polysilicon TFT, LTPSTFT) driving board, or an oxide TFT (Organic TFT, OTFT) driving board, etc.

[0057] In addition, a bonding area is also provided on the substrate 10, and a chip on film (COF) 82 is connected to the bonding area through a pad 81.

[0058] Figure 3Schematic diagram of the detailed structure of the OLED light-emitting device in the display panel provided by an embodiment of the present application.

[0059] Generally speaking, according to the different ways of coupling and extracting light of the device, OLED devices can be divided into top-emitting OLED devices and bottom-emitting OLED devices. Compared with bottom-emitting OLEDs, when top-emitting OLEDs are combined with TFT driving boards for active matrix displays, they do not affect the aperture ratio of the device. Therefore, this kind of top-emitting structure OLED is more suitable for application in active matrix displays.

[0060] In the embodiment of the present application, the OLED light-emitting device 30 is taken as an example of a top-emitting OLED device for illustration. As Figure 3 shown, the OLED light-emitting device 30 includes a plurality of functional layers stacked in sequence along the thickness direction D of the display panel 100. The plurality of functional layers include an anode 31, a light-emitting layer 32, an organic layer 33, a cathode 34, a pixel defining layer 35, etc., and the functional layers also include a light extraction layer 36. Among them, the anode 31 is disposed on the substrate 10, and the anode 31 is electrically connected to the drain or source of the thin-film transistor in the TFT driving board through a via hole disposed inside a flat layer (not shown) of the substrate 10 (not shown). The anode 31 provides holes in the OLED device. The light-emitting layer 32 is used to transport electrons and holes and recombine to form excitons, thereby generating light emission. The pixel defining layer 35 defines pixel regions, and a plurality of pixel regions together form the display region of the display panel 100. In each pixel region, the above-mentioned anode 31, light-emitting layer 32, organic layer 33, and cathode 34 are stacked in sequence.

[0061] In the embodiment of the present application, in combination with Figure 1 、 Figure 2 、 Figure 3 , the projection of the first magnetic layer 50 on the substrate 10 is located in the border region. A polarizer 70 is provided on the surface of the encapsulation cover plate 20 facing away from the substrate 10. The orthographic projection of the polarizer 70 on the substrate 10 covers the display region A. The first magnetic layer 50 is disposed around the polarizer 70. In this way, the first magnetic layer 50 is formed into an annular structure, which can protect the spacer region 41 within the entire circumference. The first magnetic layer 50 surrounding the circumferential outer side of the polarizer 70 can also avoid affecting the display region corresponding to the polarizer 70.

[0062] Preferably, the edge of the orthographic projection of the polarizer 70 on the substrate 10 is located in the spacer region 41; the inner edge of the first magnetic layer 50 is adjacent to the outer edge of the polarizer 70.

[0063] In this way, the polarizer 70 can cover the display region of the display panel 100 as much as possible to avoid light leakage. And the inner edge of the first magnetic layer 50 being adjacent to the outer edge of the polarizer 70 can increase the area of the first magnetic layer 50 above the spacer region 41 as much as possible.

[0064] In some other embodiments, a structure in which the inner edge of the first magnetic layer 50, which may also be part of it, covers the outer edge of the polarizer 70 can be adopted. In this way, the area of the first magnetic layer 50 above the spacer region 41 can be increased as much as possible, so that the protection effect on the display panel 100 is better.

[0065] In the embodiments of the present application, with continued reference to Figure 3 , the projection of the second magnetic layer 60 on the substrate 10 is located in the border region; a support layer 80 is provided on the surface of the substrate 10 on the side facing away from the encapsulation cover plate 20, and the second magnetic layer 60 is arranged around the support layer 80. In this way, the second magnetic layer 60 also forms an annular structure, which can protect the spacer region 41 within the entire circumference.

[0066] Exemplarily, the inner edge of the second magnetic layer 60 is adjacent to the outer edge of the support layer 80, so that the flatness of the back surface of the display panel 100 is better.

[0067] In some embodiments, the inner edge of the positive projection of the second magnetic layer 60 on the substrate 10 completely coincides with the inner edge of the positive projection of the first magnetic layer 50 on the substrate 10. And / or the outer edge of the positive projection of the second magnetic layer 60 on the substrate 10 completely coincides with the outer edge of the positive projection of the first magnetic layer 50 on the substrate 10. In this way, the first magnetic layer 50 and the second magnetic layer 60 can be arranged opposite to each other in the thickness direction D.

[0068] In the embodiments of the present application, exemplarily, the entire second magnetic layer 60 covers the surface of the substrate 10 facing away from the encapsulation cover plate 20, and a support layer is further provided on the surface of the second magnetic layer 60 facing away from the substrate 10. In this way, the second magnetic layer 60 can play an auxiliary supporting role for the display panel 100, and the design flexibility of the position of the first magnetic layer 50 is also relatively high. In other words, even if the setting position of the first magnetic layer 50 deviates due to processes or other reasons, it can be ensured that there is always a part that is opposite to the second magnetic layer 60.

[0069] In the embodiments of the present application, the first magnetic layer 50 and the second magnetic layer 60 can be permanent magnetic layers formed of permanent magnetic materials. Or the first magnetic layer 50 and the second magnetic layer 60 can also be both constructed as electromagnetic layers, and the first magnetic layer 50 and the second magnetic layer 60 are configured to generate a repulsive force when energized. Compared with permanent magnetic materials, when the first magnetic layer 50 and the second magnetic layer 60 are electromagnetic layers, they only generate magnetism when energized, which can avoid the possible adverse effects on the display of the display panel 100 caused by the first magnetic layer 50 and the second magnetic layer 60. In other words, the first magnetic layer 50 and the second magnetic layer 60 only generate magnetism when energized, and when not energized, they do not have magnetism, which can avoid affecting the normal display of the display panel 100.

[0070] It should be noted that the repulsive force between the first magnetic layer 50 and the second magnetic layer 60 is less than the adhesive force between the encapsulation cover plate 20, the substrate 10 and the encapsulation layer 40, so as to avoid the situation where the encapsulation layer 40 is peeled off from the encapsulation cover plate 20 and the substrate 10.

[0071] In the embodiment of the present application, the display panel 100 further includes an acceleration sensor and a controller (not shown). Among them, the acceleration sensor is used to detect the acceleration information of the display panel 100.

[0072] The controller is electrically connected to the acceleration sensor, the first magnetic layer 50 and the second magnetic layer 60 respectively. The controller is configured to judge whether the display panel 100 is in a weightless state according to the acceleration information detected by the acceleration sensor, and when it is judged that the display panel 100 is in a weightless state, control the first magnetic layer 50 and the second magnetic layer 60 to be energized.

[0073] In this way, the controller obtains the state of the display panel 100 through the acceleration sensor. When it is judged that the display panel 100 is in a weightless state, the first magnetic layer 50 and the second magnetic layer 60 are turned on, and a repulsive force is generated. In this way, when the display panel 100 is in a weightless state, the first magnetic layer 50 and the second magnetic layer 60 are energized, while when the display panel 100 is in a normal use state, the first magnetic layer 50 and the second magnetic layer 60 are not energized and do not generate magnetism. In other words, the acceleration sensor functions as a switch for turning on and off the first magnetic layer 50 and the second magnetic layer 60.

[0074] Preferably, the controller is configured to judge that the display panel is in a weightless state when the acceleration information detected by the acceleration sensor is greater than a preset threshold.

[0075] It can be understood that the first magnetic layer 50 is bonded to the encapsulation cover plate 20 by an adhesive; and / or the second magnetic layer 60 is bonded to the substrate 10 by an adhesive. In this way, the first magnetic layer 50 and the encapsulation cover plate 20 can have good bonding properties, so that when the first magnetic layer 50 is subjected to the repulsive force of the second magnetic layer 60, the repulsive force can be transmitted to the encapsulation cover plate 20. Similarly, the second magnetic layer 60 and the substrate 10 can have good bonding properties, so that when the second magnetic layer 60 is subjected to the repulsive force of the first magnetic layer 50, the repulsive force can be transmitted to the substrate 10. Here, the adhesive can be an OCA optical adhesive. Or, in some embodiments, the first magnetic layer 50 can also be formed by printing a magnetic material on the encapsulation cover plate 20; and / or the second magnetic layer 60 can be formed by printing a magnetic material on the substrate 10. For the energization of the first magnetic layer 50 and the second magnetic layer 60, for example, the power supply can be connected by common methods such as ACF pressing or soldering to achieve the purpose of energization.

[0076] An embodiment of the second aspect of the present application provides a display device, including the display panel 100 in any of the embodiments of the first aspect above.
