Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display panel and display device. Background Technology

[0002] Currently, display devices such as smartphones, tablets, and smart TVs have become an indispensable part of people's work and life. To improve the user experience and meet the demand for high screen-to-body ratios, slots or holes are usually made in the display panel to accommodate components such as cameras and sensors, resulting in notch screens, waterdrop screens, and punch-hole screens. Among these, punch-hole screens are the most widely used, offering advantages such as a large screen-to-body ratio, minimal disruption to the overall screen integrity, high aesthetic appeal, and strong display capabilities. They are favored by manufacturers and consumers and have a promising future. However, in related technologies, when the display area of ​​the panel is lit, some lateral light shines towards the opening. Due to limitations in the coverage width and thickness of the inkjet printing (IJP) layer around the opening, light leakage is prone to occur at the edge of the opening, thus reducing the display effect. Summary of the Invention

[0003] In view of the above, this application aims to provide a display panel and display device to solve the aforementioned technical problems.

[0004] For the purposes described above, this application provides a display panel, including:

[0014] Optionally, the display panel further includes:

[0015] A dam is disposed on the side of the substrate near the light-absorbing layer. Its orthographic projection on the substrate is covered by the orthographic projection of the light-absorbing layer on the substrate. The distance between the dam and the opening is less than the distance between the inkjet printing layer and the opening.

[0016] Optionally, the height of the dam is greater than or equal to the thickness of the inkjet printed layer.

[0017] Optionally, the display panel further includes:

[0018] An isolation structure is disposed on the side of the substrate near the light-absorbing layer, and the orthogonal projection of the light-absorbing layer on the substrate is covered by the orthogonal projection of the light-absorbing layer on the substrate.

[0023] Optionally, the display panel includes:

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0044] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains.

[0045] In related technologies, OLED (Organic Light-Emitting Diode) display panels are common and widely used in display devices such as smartphones, tablets, and smart TVs. For a display panel, it mainly includes the display area A / A and the non-display area N / A. The punch-hole area on the display panel is a typical non-display area N / A, which includes the transition boundary 220 and the opening 210. (See [link to relevant documentation]). Figure 1The display area A / A of the display panel is the working area of ​​the display panel. The larger the display area A / A is, the higher the screen ratio and the better the visual effect. The opening 210 in the non-display area N / A is used to accommodate electronic components such as cameras and sensors in the display device, and is usually located at the top of the display panel. The transition boundary 220 is set between the display area and the opening 210, which can block the display area A / A of the display panel from entering the display area A / A through the opening 210, thereby extending the service life of the display panel.

[0046] During use, the display area A / A of the display panel is in an active state, i.e., the display area A / A is lit. At this time, the side light generated by the display area A / A shines towards the opening 210. To prevent light leakage at the edge of the opening 210, an inkjet printed layer 420 is usually provided on the transition boundary 220 to block the side light. However, since the width of the transition boundary 220 is relatively narrow and the inkjet printed layer 420 is in a fluid state, light leakage is prone to occur at the edge of the opening 210 due to the limited coverage width and thickness of the inkjet printed layer 420 around the opening 210. In addition, when side light from the outside shines on the edge of the opening 210, i.e., near the transition boundary 220, the side light passes through the surface of the display panel and shines on the TFTs (Thin Film Transistors) distributed on the substrate 100. On the thin-film transistor (TFT, not shown in the figure), due to the reflective effect of the TFT, side light will reflect at the edge area of ​​the opening 210, resulting in a more obvious color deviation at the edge area of ​​the opening 210, thereby reducing the display effect of the display panel.

[0047] To achieve the above objectives, this application provides a display panel including a substrate 100; an opening 210 disposed on the substrate 100; and a light-absorbing layer 300 disposed around the opening 210, the orthogonal projection of which is located within the substrate 100 and configured to absorb lateral light irradiated on the edge region of the opening 210.

[0048] Specifically, please refer to Figures 2A-4CIn this application, the substrate 100 is used to support and protect the various components and film structures in the display panel, and to give the back of the display panel good water and oxygen barrier capabilities, ensuring the normal use of the display panel; an opening 210 is provided in the non-real area N / A of the display panel, which can accommodate electronic components such as cameras and sensors in the display device; a light-absorbing layer 300 is disposed around the opening 210 and within the transition boundary 220. Therefore, when the display panel is working, the display area A / A of the display panel is lit up, and some of the side light generated by the display area A / A will shine towards the opening 210. Since the light-absorbing layer 300 is disposed around the opening 210, and its orthogonal projection on the substrate 100 is located within the substrate 100, it can absorb the side light shining towards the opening 210, thereby avoiding light leakage in the edge area of ​​the opening 210 and ensuring the display effect of the display panel.

[0049] Furthermore, since the light-absorbing layer 300 is arranged around the opening 210 and its orthographic projection on the substrate 100 is located within the substrate 100, it can cover the transition boundary 220. When external side light shines on the transition boundary 220, the side light will pass through the surface of the display panel and shine on the light-absorbing layer 300. Since the light-absorbing layer 300 has a light-absorbing effect, the side light cannot pass through the light-absorbing layer 300 and shine on the TFT on the substrate 100. Therefore, no reflection phenomenon will occur inside the display panel, thereby avoiding the color deviation problem in the edge area of ​​the opening 210. The light-absorbing layer 300 can be formed by adding organic materials such as carbon black light absorbers, which can not only absorb the side light of the display panel and the side light from the outside, but also play a planarizing role on the surface of the substrate 100.

[0050] In some embodiments, the substrate 100 may include a first substrate layer 110, an inorganic layer 120, and a second substrate layer 130, which are stacked sequentially from top to bottom. (See also...) Figures 2A-4C The first substrate layer 110 serves as a support for the display panel, supporting and protecting the film structure and various components arranged on the substrate 100. The inorganic layer 120 can be formed on the upper surface of the first substrate layer 110, which can improve the water and oxygen barrier capability of the substrate 100 and extend the service life of the display panel. The second substrate layer 130 can be formed on the upper surface of the inorganic layer 120, which can further enhance the strength of the substrate 100. In addition, it should be noted that the first substrate layer 110 and the second substrate layer 130 in the substrate 100 can be formed using at least one of inorganic materials such as imide polymers and amide polymers, and the inorganic layer 120 can be formed using at least one of organic materials such as silicon, silicon oxide, silicon nitride, silicon oxynitride, and aluminum oxide, to ensure that the substrate 100 has good load-bearing capacity and barrier effect.

[0051] In some embodiments, the light-absorbing layer 300 includes a first light-absorbing surface 300a disposed on a side close to the substrate 100 and a second light-absorbing surface 300b disposed on a side away from the substrate 100; wherein the first light-absorbing surface 300a is configured to absorb lateral light irradiated toward the opening 210; and the second light-absorbing surface 300b is configured to absorb lateral light irradiated toward the second light-absorbing surface 300b.

[0052] Specifically, since the light-absorbing layer 300 is disposed around the opening 210, it can absorb side light illuminating towards the opening 210, preventing light leakage from the display panel at the edge of the opening 210. Simultaneously, the light-absorbing layer 300 can also absorb side light illuminating the surface of the display panel, reducing the reflective effect at the edge of the opening 210 and lowering the color deviation in that area. The light-absorbing layer 300 may include a first light-absorbing surface 300a and a second light-absorbing surface 300b. (See also...) Figure 2A-4C For the first light-absorbing surface 300a, when the display area A / A of the display panel is lit, some of the side light generated will irradiate towards the opening 210. By setting the light-absorbing layer 300 in the edge area of ​​the opening 210 and setting the second light-absorbing surface 300b of the light-absorbing layer 300 close to the substrate 100, the second light-absorbing surface 300b can absorb the side light irradiated towards the opening 210, so that the side light cannot be emitted from the edge area of ​​the opening 210, thus avoiding light leakage from the display panel.

[0053] As for the second light-absorbing surface 300b of the light-absorbing layer 300, the second light-absorbing surface 300b is disposed on the side away from the substrate 100. Therefore, when external side light shines on the display panel, the side light passes through the surface of the display panel and shines on the second light-absorbing surface 300b of the light-absorbing layer 300. The second light-absorbing surface 300b absorbs the external side light shining on its surface, so that the side light does not shine on the TFT of the substrate 100. Therefore, the TFT will not emit light, thereby reducing the color deviation in this area and ensuring the display effect of the display panel.

[0054] In some embodiments, the display panel further includes a first encapsulation layer 410 disposed on the side of the substrate 100 near the light-absorbing layer 300, with its orthographic projection on the substrate 100 located within the substrate 100; an inkjet printing layer 420 disposed on the side of the first encapsulation layer 410 near the light-absorbing layer 300, with its orthographic projection on the first encapsulation layer 410 located within the first encapsulation layer 410; and a second encapsulation layer 430 disposed on the side of the inkjet printing layer 420 near the light-absorbing layer 300, with its orthographic projection on the first encapsulation layer 410 covering the orthographic projection of the inkjet printing layer 420 on the first encapsulation layer 410.

[0055] Specifically, please refer to Figure 2A , Figure 3A and Figure 4A An inkjet-printed layer 420 is disposed on the side of the substrate 100 near the light-absorbing layer 300, and the inkjet-printed layer 420 is located between the substrate 100 and the light-absorbing layer 300. By disposing of the inkjet-printed layer 420 between the display area A / A and the opening 210 of the display panel, a portion of the lateral light generated by the display area A / A can be absorbed, reducing the light leakage of the opening 210 area. It can also encapsulate the edge area of ​​the opening 210 to prevent external water and oxygen from entering the display area A / A of the display panel through the opening 210. The inkjet-printed layer 420 can be prepared on the substrate 100 using inkjet coating technology. Since the material of the inkjet-printed layer 420 is in a fluid state, in order to prevent the ink in the inkjet-printed layer 420 from flowing out, the inkjet-printed layer 420 can be encapsulated by the first encapsulation layer 410 and the second encapsulation layer 430 to form a corresponding film encapsulation structure, ensuring the stability of the inkjet-printed layer 420.

[0056] In some embodiments, the display panel further includes a dam 500 disposed on the side of the substrate 100 near the light-absorbing layer 300, the orthographic projection of the light-absorbing layer 300 on the substrate 100 being covered by the orthographic projection of the light-absorbing layer 300 on the substrate 100, and the distance between the dam 500 and the opening 210 being less than the distance between the inkjet printing layer 420 and the opening 210, wherein the height of the dam 500 is greater than or equal to the thickness of the inkjet printing layer 420.

[0057] Specifically, please refer to Figure 2A , 3A In this application, the first encapsulation layer 410 and the second encapsulation layer 430 can be used to seal the inkjet printing layer 420, so that the inkjet printing layer 420 has good water and oxygen barrier capabilities and good stability. In particular, by setting the distance between the baffle 500 and the opening 210 to be less than the distance between the inkjet printing layer 420 and the opening 210, and by setting the baffle 500 around the opening 210, the baffle 500 can be positioned between the opening 210 and the inkjet printing layer 420, thereby playing a certain blocking role for the inkjet printing layer 420 and preventing the inkjet printing layer 420 from flowing out towards the opening 210 after being pressed. Furthermore, by setting the height of the baffle 500 to be greater than the thickness of the inkjet printing layer 420, the outflow of the inkjet printing layer 420 can be blocked. When the surface of the display panel is pressed, the baffle 500 can share the pressure with the inkjet printing layer 420, further improving the blocking effect of the baffle 500 on the inkjet printing layer 420.

[0058] In some embodiments, the display panel further includes an isolation structure disposed on the side of the substrate 100 near the light-absorbing layer 300, wherein the orthographic projection of the light-absorbing layer 300 on the substrate 100 is covered by the orthographic projection of the light-absorbing layer 300 on the substrate 100; wherein the isolation structure includes at least one isolation groove 610, the distance between any isolation groove 610 and the opening 210 being less than the distance between the dam 500 and the opening 210; and / or at least one isolation pillar 620, the distance between any isolation pillar 620 and the opening 210 being less than the distance between the dam 500 and the opening 210.

[0059] Specifically, please refer to Figures 2A-4C An isolation structure is provided on the substrate 100, and this isolation structure can be distributed within the transition boundary 220, positioned between the dam 500 and the opening 210. By providing an isolation structure between the dam 500 and the opening 210, a barrier structure that blocks water and oxygen can be formed between the display area A / A of the display panel and the opening 210, improving the display panel's ability to block water and oxygen. In this application, the isolation structure can include isolation pillars 620 and / or isolation grooves 610, both of which can achieve water and oxygen blocking. At the same time, since the orthographic projection of the isolation structure on the substrate 100 is covered by the orthographic projection of the light-absorbing layer 300 on the substrate 100, external lateral light will be absorbed by the light-absorbing layer 300, thus preventing reflection and avoiding color deviation. Furthermore, by providing an isolation structure on the substrate 100, the connection effect between corresponding film layers in the display panel can be improved, resulting in better adhesion between the film layers.

[0060] For example, please see Figures 2A-2C When the isolation structure includes an isolation trench 610, the surface of the substrate 100 can be etched using an etching process to form a groove structure, i.e., the isolation trench 610, between the dam 500 and the opening 210. When forming other film layers of the display panel subsequently, through-holes can be created in other film layers using an etching process, and these through-holes can be connected to the isolation trench 610. When forming the light-absorbing layer 300, the light-absorbing layer 300 fills the through-hole and isolation trench 610, forming corresponding protrusion structures. Since the protrusion structures distributed on the light-absorbing layer 300 penetrate multiple... The membrane layer can improve the bonding strength between the various membrane layers, and also play a certain barrier role to prevent water and oxygen from entering the display area A / A of the display panel through the opening 210. As for the isolation groove 610, the isolation groove 610 can be set as multiple dots, and the multiple dotted isolation grooves 610 can be evenly distributed in the area between the dam 500 and the opening 210 to form a barrier zone between the two. In addition, the isolation groove 610 can also be set as parallel strips or rings, which can also play a good barrier effect against water and oxygen at the opening 210.

[0061] For example, please see Figures 3A-3C When the isolation structure includes isolation pillar 620, the isolation pillar 620 can utilize SD electrodes (Source and...) distributed on the substrate 100 near the light-absorbing layer 300. Drain (source / drain electrode) effectively reduces the cost of additionally fabricating isolation pillars 620. Since the isolation pillars 620 are protruding on the substrate 100, when the light-absorbing layer 300 and other films are formed on the substrate 100, each film fills the gaps between the isolation pillars 620, causing a corresponding protruding structure to form on the lower surface of the film in contact with the isolation pillars 620. This increases the friction between the film layers and improves the connection between them. The protruding structure at the bottom of the film and the isolation pillars 620 abut against each other, greatly improving the sealing performance and effectively preventing external water and oxygen molecules from entering the display area A / A of the display panel through the opening 210. Furthermore, when using SD electrodes as isolation pillars 620, annular grooves can be etched on the side of the isolation pillars 620 to increase the tightness between the film covering the isolation pillars 620 and the substrate 100, thereby further improving the interlayer adhesion of the display panel.

[0062] For example, please see Figures 4A-4C When the isolation structure employs both isolation pillars 620 and isolation grooves 610, an alternating barrier structure can be formed between the opening 210 and the display area A / A to improve the water and oxygen barrier capability of the display panel. Since the isolation structure has both isolation pillars 620 and isolation grooves 610, it can have the beneficial effects produced by both isolation pillars 620 and isolation grooves 610, which will not be elaborated here.

[0063] In some embodiments, the display panel includes a metal layer 710 disposed on the side of the substrate 100 near the light-absorbing layer 300, and has a connection hole corresponding to the isolation trench 610, the width of which is greater than the width of the isolation trench 610; and / or is disposed on the side of the isolation pillar 620 near the substrate 100.

[0064] Specifically, please refer to Figure 2A , Figure 3A and Figure 4AThe metal layer 710 can be disposed on the side of the display panel near the light-absorbing layer 300. When the isolation structure includes an isolation groove 610, the metal layer 710 and the corresponding film layer above the metal layer 710 are provided with connection holes. Each connection hole corresponds to an isolation groove 610, allowing the light-absorbing layer 300 formed later to pass through the connection hole and enter the groove to form a protrusion, thereby improving the connection strength between the film layers and enhancing the water and oxygen barrier capability of the display panel. Similarly, when the isolation structure includes an isolation pillar 620, the isolation pillar 620 is disposed on the metal layer 710 to allow the later-formed light-absorbing layer 300 to pass through the connection hole and enter the groove to form a protrusion, thereby improving the connection strength between the film layers and enhancing the water and oxygen barrier capability of the display panel. The formed film layers cover the isolation pillar 620, increasing the contact area with the isolation pillar 620, which can also improve the adhesion between the film layers and enhance the water and oxygen barrier ability of the display panel. Among them, the metal layer 710 can serve as the electrode layer of the display panel, and can be formed by transparent conductive materials such as indium tin oxide, indium zinc oxide, zinc oxide, and indium oxide, or by metals such as lithium, calcium, lithium fluoride / calcium, lithium fluoride / aluminum, aluminum, silver, magnesium, and gold. In addition, the metal layer 710 is also covered with a light-emitting layer 720, which serves as the light-emitting unit of the display panel and can be formed by electroluminescent materials, which will not be described in detail here.

[0065] In some embodiments, touch traces 810, detection traces 820, and ground traces 830 are respectively provided on the side of the light-absorbing layer 300 away from the substrate 100. The touch traces 810, detection traces 820, and ground traces 830 are all arranged around the opening 210.

[0066] Specifically, please refer to Figure 2A , 3A 4A and Figure 5 A touch trace 810, a detection trace 820, and a ground trace 830 are arranged on the side of the light-absorbing layer 300 away from the substrate 100. At least one touch trace 810, a detection trace 820, and a ground trace 830 are provided, and they all surround the opening 210. By arranging the touch trace 810 between the display area A / A and the opening 210, the touch area of ​​the display panel can be expanded, and the touch sensitivity around the opening 210 can be improved, allowing the user to better interact with the display panel opening 210. Touch operation is performed in the vicinity of the opening 210. Since the opening 210 is located on the display panel, detection traces 820 can be set around the opening 210 before the display panel leaves the factory to detect the circuit connection around the opening 210, thereby improving the yield rate of the display panel. In addition, grounding traces 830 are also distributed around the opening 210, which can conduct and transfer static electricity in the edge area of ​​the opening 210, avoiding static electricity accumulation in the edge area of ​​the opening 210 and damaging the display panel, thus effectively protecting the circuit around the display panel.

[0067] It should be noted that a trace encapsulation layer 840 can be formed on the side of the light-absorbing layer 300 away from the substrate 100. This layer can fix and protect the touch traces 810, detection traces 820, and ground traces 830, and can also prevent crosstalk between the traces. The touch traces 810, detection traces 820, and ground traces 830 can be set as metal traces and can be formed by opaque metals such as lithium, calcium, lithium fluoride / calcium, lithium fluoride / aluminum, aluminum, silver, magnesium, and gold. This can provide a certain light-shielding effect and reduce the amount of light entering the display panel to a certain extent.

[0068] Based on the same inventive concept, this application also provides a display device, including a display panel as described in any of the above embodiments; wherein, since the display device has the above-described display panel, the display device possesses all the advantages and beneficial effects of the above-described display panel; in addition, the display device in this application can be any product or component with display function, such as a mobile phone, computer, television, and multimedia display device, which will not be described in detail in this application.

[0069] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of this application (including the claims) is limited to these examples; within the framework of this application, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of the embodiments of this application as described above, which are not provided in the details for the sake of brevity.

[0070] Furthermore, to simplify the description and discussion, and to avoid obscuring the embodiments of this application, the apparatus may be shown in block diagram form in the provided drawings. This is to avoid making the embodiments of this application difficult to understand, and it also takes into account the fact that the details of the implementation of these block diagram apparatuses are highly dependent on the platform on which the embodiments of this application will be implemented (i.e., these details should be fully within the understanding of those skilled in the art).
