Display panel and display device

Abstract

This application provides a display panel and a display device. The display panel includes a display area, a first non-display area, and a second non-display area. The display area at least partially surrounds the first non-display area, and the second non-display area surrounds the display area. In a direction perpendicular to the plane of the display panel, the display panel includes a substrate and a touch layer, with the touch layer disposed on one side of the substrate. Along the direction from the display area toward the first non-display area, the projection of the edge of the touch layer onto the substrate does not overlap with the edge of the substrate. That is, the edge of the touch layer near the first non-display area is not flush with the edge of the substrate near the first non-display area. Therefore, when the first non-display area of ​​the display panel is cut, the touch layer experiences less stress release due to the non-flushness of its edge with the substrate edge. This reduces the probability of gaps appearing between different film layers in the display panel due to stress release during cutting, thereby improving the performance of the display panel.

Description

Technical Field

[0001] This invention relates to the field of display technology, and in particular to a display panel and display device. Background Technology

[0002] Current display technology is mainly divided into liquid crystal display (LCD), organic light-emitting diode (OLED), and micro-LED displays. Different types of display panels can be applied in a variety of fields; for example, all three types of display panels mentioned above can be used in terminal devices.

[0003] The display panel includes an area for mounting cameras, requiring it to be cut to create space for the cameras. However, during the actual cutting process, stress release issues arise between the different film layers in the display panel after cutting, leading to gaps and a decrease in display panel performance. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a display panel and display device that can reduce the gaps between different film layers in the display panel and improve the performance of the display panel.

[0005] This application provides a display panel, which includes a display area, a first non-display area, and a second non-display area. The display area at least partially surrounds the first non-display area, and the second non-display area surrounds the display area.

[0006] In the direction perpendicular to the plane of the display panel, the display panel includes a substrate and a touch layer, the touch layer being disposed on one side of the substrate; along the direction from the display area toward the first non-display area, the projection of the edge of the touch layer onto the substrate does not overlap with the edge of the substrate.

[0007] This application provides a display device, including a display panel as described in the above embodiments.

[0008] The display panel provided in this application embodiment includes a display area, a first non-display area, and a second non-display area. The display area at least partially surrounds the first non-display area, and the second non-display area surrounds the display area. Specifically, the first non-display area is the area where a camera can be installed. In the direction perpendicular to the plane of the display panel, the display panel includes a substrate and a touch layer, with the touch layer disposed on one side of the substrate. Along the direction from the display area toward the first non-display area, the projection of the edge of the touch layer onto the substrate does not overlap with the edge of the substrate. That is, the edge of the touch layer near the first non-display area is not flush with the edge of the substrate near the first non-display area. Therefore, when the first non-display area of ​​the display panel is cut, the touch layer experiences less stress release due to the non-flushness of its edge with the substrate edge. This reduces the probability of gaps appearing between different film layers in the display panel due to stress release during cutting, thereby improving the performance of the display panel.

[0018] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0020] Secondly, this application provides a detailed description in conjunction with schematic diagrams. When detailing the embodiments of this application, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this application. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0021] Current display technology is mainly divided into liquid crystal display (LCD), organic light-emitting diode (OLED), and micro-LED displays. Different types of display panels can be applied in a variety of fields; for example, all three types of display panels mentioned above can be used in terminal devices.

[0022] The display panel includes a cutout area 101 for mounting the camera; the display panel needs to be cut to create space for the camera. (Reference) Figure 1 The diagram shown is a cross-sectional view of a display panel. The display panel includes a substrate 10, an encapsulation film layer 20, and a touch film layer 30 stacked sequentially. When the display panel is cut, the substrate 10, the encapsulation film layer 20, and the touch film layer 30 are all cut to obtain space for setting the camera.

[0023] However, during the actual cutting of the display panel, the touch film layer 30 is under great stress, and there is a problem of stress release after the touch film layer 30 is cut. This causes the encapsulation film layer 20 to peel away from the substrate 10, that is, a gap appears between the encapsulation film layer 20 and the substrate 10, which in turn leads to a decrease in the performance of the display panel.

[0024] Based on this, embodiments of this application provide a display panel including a display area, a first non-display area, and a second non-display area. The display area at least partially surrounds the first non-display area, and the second non-display area surrounds the display area. That is, the first non-display area is an area where a camera can be installed. In the direction perpendicular to the plane of the display panel, the display panel includes a substrate and a touch layer, with the touch layer disposed on one side of the substrate. Along the direction from the display area toward the first non-display area, the projection of the edge of the touch layer onto the substrate does not overlap with the edge of the substrate. In other words, the edge of the touch layer near the first non-display area is not flush with the edge of the substrate near the first non-display area. Therefore, when the first non-display area of ​​the display panel is cut, the touch layer experiences less stress release due to the non-flushness of its edge with the substrate edge. This reduces the probability of gaps appearing between different film layers in the display panel due to stress release during cutting, thereby improving the performance of the display panel.

[0025] To better understand the technical solution and effects of this application, the specific embodiments will be described in detail below with reference to the accompanying drawings.

[0026] refer to Figure 2 The diagram shown is a structural schematic of a display panel 100 provided in an embodiment of this application. Figure 3 It is along Figure 2 A schematic diagram of the cross-sectional structure of the display panel taken from the direction where BB is located.

[0027] The display panel 100 provided in this application embodiment can be a rigid display panel or a flexible display panel. A rigid display panel is hard and not easily bent or folded, while a flexible display panel is flexible and can be easily bent, folded, or rolled up. For example, the display panel 100 can be a foldable display panel that can be folded and unfolded, a curved display panel with a curved display surface, a curved display panel with an area other than the curved display surface, a rollable display panel that can be rolled up and / or unfolded, or a stretchable display panel that can be stretched and / or not stretched, etc.

[0028] The display panel 100 provided in this application embodiment includes a display area AA and a non-display area NA. The non-display area NA includes a first non-display area NA1 and a second non-display area NA2. The display area AA at least partially surrounds the first non-display area NA1. Specifically, the first non-display area NA1 may be located within the display area AA. For example, the first non-display area NA1 may be a camera area used to house a camera. The second non-display area NA2 surrounds the display area AA. The second non-display area NA2 may be, for example, a border area. The display area AA is the area used for display, and the second non-display area NA2 is the area used to house the circuit structure that drives the display panel to display. The display area AA may occupy most of the display panel area and may be located at the center of the display panel, for example, the central area. The second non-display area NA2 is the area outside the display area AA and may be defined as the edge area of ​​the display panel, for example, the peripheral area.

[0029] The display panel 100 provided in this application embodiment includes a substrate 110. The substrate 110 may include an insulating material (e.g., it may be made of an insulating material), which may be glass, quartz, or polymer resin. The substrate 110 may be a flexible substrate that can be bent, folded, and / or rolled. As an example, the substrate 110 may include polyimide.

[0030] Specifically, substrate 110 may include a first substrate, a second substrate, and an inorganic barrier layer. In this configuration, each of the first and second substrates may include at least one polymer resin, such as polyethersulfone, polyacrylate, polyetherimide, polyethylene naphthalate, polyethylene terephthalate, polyphenylene sulfide, polyarylate, polyimide, polycarbonate, or cellulose acetate propionate. The first and second substrates may be made of the same material or different materials. The structure of substrate 110, including the polymer resin and the inorganic barrier layer, allows the display panel to be bent, folded, and / or rolled. It also enhances the flatness and temperature stability of substrate 110, facilitating the subsequent fabrication of other film layers on its surface and enabling it to withstand subsequent processing steps. Simultaneously, it further reduces the risk of film peeling during bending of the display panel and blocks the influence of mobile charges on the thin-film transistor channels, thereby improving display quality.

[0031] The display panel 100 provided in this embodiment includes a touch layer 150, which is located on one side of a substrate 110. The touch layer 150 includes touch electrodes, which can be disposed in the display area AA for receiving touch signals from the user. The touch electrodes include a first touch electrode and a second touch electrode. When the first touch electrode is a sensing electrode, the second touch electrode is a driving electrode; when the first touch electrode is a driving electrode, the second touch electrode is a sensing electrode. Touch detection based on the mutual capacitance principle is achieved through the first and second touch electrodes.

[0032] When cutting the first non-display area NA1 of the display panel 100, both the substrate 110 and the touch layer 150 need to be cut to create space for the camera. To reduce stress on the touch layer 150 during cutting, the projection of the edge of the touch layer 150 onto the substrate 110 along the direction from the display area AA towards the first non-display area NA1 does not overlap with the edge of the substrate 110. (Refer to...) Figure 3 As shown. That is to say, along the direction from the display area AA toward the first non-display area NA1, the edge of the touch layer 150 is not flush with the edge of the substrate 110. This way, the touch layer 150 will not be cut when the substrate 110 is cut, the stress release is small, and the probability of gaps between different film layers in the display panel due to stress release when the touch layer 150 is cut is avoided, thereby improving the performance of the display panel.

[0033] Specifically, the first non-display area NA1 may include a punch-hole area 101, which may be used to house a light-sensing device, such as a camera. (See reference...) Figure 2 and Figure 3 As shown. The punch-hole area 101 includes a cut line along the direction from the display area AA toward the first non-display area NA1. The cut line is used to divide the punch-hole area 101 and the area in the first non-display area NA1 containing the substrate 110. The cut line of the punch-hole area 101 is used to form the punch-hole area 101 so that a photosensitive device can be disposed in the punch-hole area 101.

[0034] The projection of the edge of the touch layer 150 onto the substrate 110 does not overlap with the cutting line, thus avoiding stress release when the display panel 100 is cut to form the punched area 101. The projection of the edge of the touch layer 150 onto the substrate 110 can be positioned on the side of the cutting line closer to the display area AA. That is, along the direction from the display area AA toward the first non-display area NA1, the cutting line is further away from the display area AA than the edge of the touch layer 150.

[0035] Along the direction from the display area AA toward the first non-display area NA1, the distance between the projection of the edge of the touch layer 150 onto the substrate 110 and the edge of the substrate 110 can be determined according to the actual situation. For example, the distance between the projection of the edge of the touch layer 150 onto the substrate 110 and the edge of the substrate 110 that minimizes the gap between different film layers after cutting can be set as the optimal distance.

[0036] In embodiments of this application, the touch layer 150 includes an inorganic layer, in which a plurality of grooves 152 may be formed, as shown in the reference. Figure 4 As shown, Figure 4 Yes Figure 3 The C region is obtained by performing a partial cross-section. The inorganic layer material may include silicon nitride and silicon oxynitride. The groove 152 can help release the stress of the touch layer 150, further reducing the gaps between film layers caused by the stress release of the touch layer 150 when cutting the display panel 100. The groove 152 can be set in the first non-display area NA1, specifically between the cutting line of the perforated area 101 and the display area AA.

[0037] Specifically, the groove 152 can penetrate the touch layer 150, which can cut the touch layer 150 located in the first non-display area NA1 into multiple unconnected segments, further assisting the touch layer 150 in releasing stress.

[0038] In embodiments of this application, a driving circuit layer 120, a light-emitting layer 130, and an encapsulation layer 140 may be sequentially stacked between the substrate 110 and the touch layer 150, as shown in the reference. Figure 3 As shown, multiple driving transistors can be disposed in the driving circuit layer 120, multiple light-emitting devices can be disposed in the light-emitting layer 130, and the encapsulation layer 140 is used to protect the light-emitting devices or driving transistors thereunder from the influence of water vapor or oxygen in the air.

[0039] The driving circuit layer 120 includes an active layer 21, a first metal layer 22, a second metal layer 24, and insulating layers between adjacent conductive layers, such as a buffer layer, a gate insulating layer, a first interlayer insulating layer, a second interlayer insulating layer, and a planarization layer. The driving circuit layer 120 may also include a third metal layer 25 and a fourth metal layer, and an insulating layer between them, not shown in the figure. Specifically, the channel of the driving transistor is located in the active layer 21, the gate of the driving transistor is located in the first metal layer 22, and the source and drain electrodes of the driving transistor are located in the second metal layer 24.

[0040] The light-emitting layer 130 includes an anode metal layer (including multiple anodes), an organic light-emitting layer, a cathode metal layer, and an insulating layer between adjacent conductive layers (such as a pixel definition layer 301). It may also include an organic material common layer 302, such as a hole injection layer, a hole transport layer, an organic light-emitting layer, an electron transport layer, and an electron injection layer.

[0041] The encapsulation layer 140 includes at least one inorganic encapsulation layer and at least one organic encapsulation layer. Figure 3 The encapsulation layer 140 shown includes a first inorganic encapsulation layer 141, a second inorganic encapsulation layer 143, and an organic encapsulation layer 142 disposed between the first inorganic encapsulation layer 141 and the second inorganic encapsulation layer 143. The first inorganic encapsulation layer 141 and the second inorganic encapsulation layer 143 may include at least one inorganic material, such as alumina, titanium oxide, tantalum oxide, hafnium oxide, zinc oxide, silicon oxide, silicon nitride, and silicon oxynitride. The organic encapsulation layer 142 may include monomeric organic materials or polymeric materials (i.e., organic encapsulation materials). Examples of polymeric materials may include acrylic resins, epoxy resins, polyimides, and polyethylene.

[0042] The first non-display area NA1 includes a retaining wall 50, see reference. Figure 3 As shown. The projection of the groove 152 on the substrate 110 can be located between the cut line of the perforation area 101 and the projection of the barrier 50 on the substrate 110. The barrier 50 is used to prevent material from spilling out of the encapsulation layer 140.

[0043] It should be noted that, Figure 3 In the diagram, some film layers are depicted using simplified methods. For example, insulating layer 20a may include a buffer layer, a gate insulating layer, a first interlayer insulating layer, and a second interlayer insulating layer; insulating layer 20b is an inorganic insulating layer; insulating layer 20c is a planarization layer; and insulating layer 20d may be an organic insulating layer. The barrier portion 50 may include insulating layer 20c, insulating layer 20d, and a pixel definition layer 301. In some optional embodiments, the barrier 50 may also include other film layers (metallic or non-metallic film layers).

[0044] As described above, when cutting the display panel 100, the encapsulation layer 140, the light-emitting layer 130, the driving circuit layer 120, and the substrate 110 are cut. The edge of the touch layer 150 does not overlap with the cutting line, thus reducing the gap between the encapsulation layer 140 and the substrate 110 when cutting the display panel 100.

[0045] In the embodiments of this application, reference is made to Figure 3As shown, the barrier 50 and the cutting line also include multiple isolation pillars 60, wherein the isolation pillars 60 are disposed in the first non-display area NA1. In the direction perpendicular to the plane of the display panel 100, the isolation pillars 60 include a first metal layer 22, a second metal layer 24, and a third metal layer 25. The isolation pillars 60 are covered by the light-emitting layer 130 and the encapsulation layer 140.

[0046] The projection of the groove 152 on the substrate 110 can overlap with the projection of the isolation post 60 on the substrate 110, see reference. Figure 4 As shown, in the direction perpendicular to the plane of the display panel 100, the groove 152 and the isolation pillar 60 overlap, with the groove 152 located above the isolation pillar 60. The isolation pillar 60 also experiences stress. By placing the groove 152 above the isolation pillar 60, the stress on the isolation pillar 60 can be released, further reducing the gap between the encapsulation layer 140 and the substrate 110 caused during the cutting of the display panel 100.

[0047] In the embodiments of this application, along the direction from the display area AA toward the first non-display area NA1, the width of the groove 152 is smaller than the width of the isolation post 60, as shown in the reference. Figure 4 As shown. At this time, the distance between the edge of the touch layer 150 and the cutting line can also be equal to the width of the groove 152. That is, by using the groove 152 or recess with a consistent width, the stress on the touch layer 150 can be uniformly released, thereby further improving the performance of the display panel.

[0048] refer to Figure 3 As shown, the distance between the edge of the touch layer 150 and the cutting line can be greater than the distance between the isolation pillar 60 closest to the cutting line and the cutting line. Specifically, in the direction perpendicular to the plane of the display panel 100, the projection of the edge of the touch layer 150 onto the substrate 110 can lie between adjacent isolation pillars 60. This results in a greater distance between the edge of the touch layer 150 and the cutting line, minimizing the impact of the stress of the touch layer 150 on the display panel during cutting at the cutting line. Furthermore, since some isolation pillars 60 are not covered by the touch layer 150, stress relief in these isolated pillars 60 also helps to reduce the gap between the encapsulation layer 140 and the substrate 110.

[0049] In the embodiments of this application, reference is made to Figure 4 As shown, along the direction from the display area AA toward the first non-display area NA1, the distance between two adjacent isolation pillars 60 is D1, and the distance between two adjacent grooves 152 is D2, where D2 > D1. That is, the distance between the grooves 152 is greater than the distance between the isolation pillars 60.

[0050] In the embodiments of this application, in a direction parallel to the plane of the display panel 100, the isolation posts 60 are arranged in a ring around the perforated area 101. The positions of the isolation posts 60 and the groove 152 overlap, therefore, the groove 152 is also ring-shaped. (Refer to...) Figure 5 As shown. The annular groove 152 can cut the touch layer 150 around the cutout area 101 into annular segments, thereby fully releasing the stress of the touch layer 150.

[0051] In embodiments of this application, a plurality of connecting slots 153 may also be provided in the touch layer 150, along the direction from the display area AA toward the first non-display area NA1, the connecting slots 153 connecting two adjacent recesses 152, as shown in the reference. Figure 5 As shown. By connecting two adjacent grooves 152 through the connecting groove 153, the touch layer 150 can be further assisted in stress relief, ultimately improving the performance of the display panel 100.

[0052] In embodiments of this application, the plurality of isolation pillars 60 include a first isolation pillar 61 and a second isolation pillar 62. The first isolation pillar 61 is located between the cutting line and the second isolation pillar 62, and the second isolation pillar 62 is located between the first isolation pillar 61 and the display area AA. The plurality of grooves 152 include a first groove 152-1 and a second groove 152-2. In a direction perpendicular to the plane of the display panel, the first groove 152-1 overlaps with the first isolation pillar 61, and the second groove 152-2 overlaps with the second isolation pillar 62. That is, the first groove 152-1 and the first isolation pillar 61 overlap, and the second groove 62 and the second isolation pillar 152-2 overlap. The height of the first isolation pillar 61 is greater than the height of the second isolation pillar 62, and the width of the first groove 152-1 is greater than the width of the second groove 152-2. (Refer to...) Figure 6 As shown, by setting the height of the first isolation pillar 61, which is closer to the first non-display area NA1, to be higher, and setting the width of the first groove 152-1, which is closer to the first non-display area NA1, to be larger, the stress release of the isolation pillar 60 and the touch layer 150 can be satisfied.

[0053] As one possible implementation, refer to Figure 5 As shown, along the direction from the display area AA toward the first non-display area NA1, the height of the isolation pillar 60 gradually increases, and the width of the groove 152 gradually increases. Since the isolation pillar 60 is taller closer to the cutting line, the stress on the isolation pillar 60 and the touch layer 150 is also greater. Therefore, by increasing the width of the groove 152, the stress release of the isolation pillar 60 and the touch layer 150 can be achieved, thereby improving the performance of the display panel 100.

[0054] Therefore, the display panel provided in this application embodiment includes a display area, a first non-display area, and a second non-display area. The display area at least partially surrounds the first non-display area, and the second non-display area surrounds the display area. That is, the first non-display area is the area where a camera can be installed. In the direction perpendicular to the plane of the display panel, the display panel includes a substrate and a touch layer, with the touch layer disposed on one side of the substrate. Along the direction from the display area toward the first non-display area, the projection of the edge of the touch layer onto the substrate does not overlap with the edge of the substrate. In other words, the edge of the touch layer near the first non-display area is not flush with the edge of the substrate near the first non-display area. Thus, when the first non-display area of ​​the display panel is cut, the touch layer experiences less stress release due to the non-flushness between its edge and the substrate edge. This reduces the probability of gaps appearing between different film layers in the display panel due to stress release during cutting, thereby improving the performance of the display panel.

[0055] Based on the display panel provided in the above embodiments, this application also provides a method for manufacturing a display panel, see reference. Figure 7 The diagram shown is a flowchart illustrating a method for manufacturing a display panel according to an embodiment of this application. The manufacturing process of the display panel provided in this embodiment includes the following steps:

[0056] The display panel provided in this application embodiment includes a display area AA and a non-display area NA. The non-display area NA includes a first non-display area NA1 and a second non-display area NA2. The display area AA at least partially surrounds the first non-display area NA1. Specifically, the first non-display area NA1 can be located within the display area AA. For example, the first non-display area NA1 can be a camera area used to house a camera. The second non-display area NA2 surrounds the display area AA. The second non-display area NA2 can be, for example, a border area. The display area AA is the area used for display, and the second non-display area NA2 is the area used to house the circuit structure that drives the display panel to display. The display area AA can occupy most of the display panel area and can be located at the center of the display panel, for example, the central area. The second non-display area NA2 is the area outside the display area AA and can be defined as the edge area of ​​the display panel, for example, the peripheral area.

[0057] S101, a touch layer is formed on one side of the substrate.

[0058] In the embodiments of this application, before forming the touch layer, a driving circuit layer, a light-emitting layer, and an encapsulation layer are sequentially stacked on one side of the substrate. The touch layer can be formed on the surface of the encapsulation layer away from the substrate, specifically using a chemical vapor deposition (CVD) process.

[0059] The touch layer includes an inorganic layer, and the material of the inorganic layer may include silicon nitride and silicon oxynitride.

[0060] S102, the touch layer is etched so that the projection of the edge of the touch layer on the substrate does not overlap with the edge of the substrate along the direction from the display area toward the first non-display area.

[0061] In the embodiments of this application, after the touch layer is formed, the touch layer can be etched so that the projection of the edge of the touch layer on the substrate along the direction from the display area toward the first non-display area does not overlap with the edge of the substrate.

[0062] The touch layer can also be etched to form grooves. These grooves can help release stress in the touch layer, further reducing gaps between film layers caused by stress release during display panel cutting. The grooves can be located in the first non-display area NA1, specifically between the cutting line of the perforated area and the display area AA.

[0063] Specifically, the groove can penetrate the touch layer, thus cutting the touch layer located in the first non-display area NA1 into multiple unconnected segments, which can further help the touch layer release stress.

[0064] In practical applications, the inorganic layer includes a buffer layer and a passivation layer. The buffer layer can be formed first using CVD technology, followed by the formation of the first touch electrode within it. Then, the passivation layer is formed using CVD, and finally, the second touch electrode is formed within it. During the formation of the second touch electrode, a groove penetrating both the buffer and passivation layers can be formed simultaneously. This integrates the groove formation process into the conventional touch electrode formation process, reducing manufacturing costs.

[0065] This application also provides a display device, including the display panel described in the above embodiments.
