Description

Technical Field

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

[0002] With the rapid development of display technology, the requirements for light transmission in the camera area of ​​the display panel are becoming increasingly stringent.

[0003] Blind holes can be incorporated into the camera area to improve its light transmittance. When blind holes are used, a light-transmitting adhesive can be filled into the holes to reduce light reflection at the substrate-gas interface, further increasing the light transmittance of the camera area. Simultaneously, a shielding layer can be placed below the encapsulation layer in the bezel area around the blind holes to reduce interference from external light and light emitted from the display area of ​​the display panel. However, the shielding layer and the light-transmitting layer overlap. Therefore, when the light-transmitting adhesive is cured by irradiating it with light, some of the adhesive is blocked and cannot cure. Summary of the Invention

[0004] The present invention provides a display panel and display device to achieve a fully solidified light-transmitting layer.

[0005] According to one aspect of the present invention, a display panel is provided, the display panel including a display area, a border area, and a light-transmitting area; the display area is disposed around the border area, and the border area is disposed around the light-transmitting area; the display panel further includes:

[0006] substrate;

[0007] A light-transmitting layer is disposed on the substrate and located in the light-transmitting area and at least a portion of the frame area;

[0008] A shielding layer is disposed on the side of the light-transmitting layer away from the substrate, and at least a portion of the shielding layer is located in the frame area; the orthographic projection of the shielding layer on the substrate overlaps with the orthographic projection of the light-transmitting layer on the substrate.

[0009] The shielding layer is used to block light with wavelengths in the visible spectrum and to allow light with wavelengths in the infrared spectrum to pass through to the light-transmitting layer; or, the border area further includes a light adjustment structure, which is used to adjust the light to the light-transmitting layer.

[0010] Optionally, the light adjustment structure includes at least one right-angle prism, at least a portion of which is disposed in the same layer as the light-transmitting layer and located on the side of the blocking layer away from the light-transmitting area; the hypotenuse of the right-angle prism is used to reflect light to the light-transmitting layer.

[0011] Optionally, the display panel further includes: an encapsulation layer disposed on the side of the shielding layer away from the substrate;

[0012] The first right-angled side of the right-angled prism is perpendicular to the film stacking direction of the display panel and is located away from the substrate. The second right-angled side of the right-angled prism is parallel to the film stacking direction of the display panel and is connected to the end of the first right-angled side near the light-transmitting area.

[0013] Alternatively, the first right-angled side of the right-angled prism is perpendicular to the film stacking direction of the display panel and located near the substrate, and the second right-angled side of the right-angled prism is parallel to the film stacking direction of the display panel and connected to the end of the first right-angled side away from the light-transmitting area.

[0014] Preferably, the first angle of the right-angle prism is greater than or equal to the critical angle for total internal reflection of the incident light; wherein, the first angle is the angle opposite to the second right-angle side.

[0015] Optionally, at least one of the right-angle prisms is disposed around the shielding layer.

[0016] Optionally, the light adjustment structure includes a plurality of right-angle prisms, which are spaced apart around the periphery of the shielding layer.

[0043] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0044] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0045] Figure 1 This is a schematic diagram of the structure of a display panel in the prior art, such as... Figure 1 As shown, the display panel includes a display area AA, a bezel area B1, and a blind aperture B2; the display area AA is at least partially disposed around the bezel area B1, and the bezel area B1 is disposed around the blind aperture B2; the display panel also includes a substrate 11; the display area AA is provided with a pixel circuit layer and a light-emitting device layer. Figure 1 (Not shown in the image) A pixel circuit layer is disposed on substrate 11, which can form a pixel driving circuit. A light-emitting device layer is disposed on the side of the pixel circuit layer away from substrate 11, which can form a light-emitting device. A camera is disposed below substrate 11 corresponding to blind hole B2. Blind hole B2 is filled with ultraviolet ray (UV) adhesive or thermosetting adhesive 12. UV adhesive or thermosetting adhesive 12 can reduce the reflection of light at the glass and gas interface and improve light transmittance. The frame area B1 is provided with multiple inorganic layers 15, which may include at least one inorganic layer extending from the display area AA. The frame area B1 is also provided with metal traces or light-shielding adhesive 13, which can block the light from the outside and the display area AA, reducing the interference of light on the camera. However, the metal traces or light-shielding adhesive 13 will overlap with the UV adhesive or thermosetting adhesive 12, which means that when the UV adhesive or thermosetting adhesive 12 is cured, the light cannot reach the overlapping area between the UV adhesive or thermosetting adhesive 12 and the metal traces 13, that is, the UV adhesive or thermosetting adhesive 12 cannot be completely cured.

[0046] To address the above problems, embodiments of the present invention provide a display panel. Figure 2 This is a schematic diagram of the structure of a display panel provided in an embodiment of the present invention. Figure 3 yes Figure 2 A sectional view along the C1-C2 direction. Figure 4 yes Figure 2 Another sectional view along the C1-C2 direction, see reference. Figure 2 , Figure 3 and Figure 4 The display panel includes a display area AA, a border area B1, and a light-transmitting area B2; the display area AA is at least partially disposed around the border area B1, and the border area B1 is disposed around the light-transmitting area B2; the display panel also includes: a substrate 101; a light-transmitting layer 102 disposed on the substrate 101 and located in the light-transmitting area B2 and at least part of the border area B1; a shielding layer 103 disposed on the side of the light-transmitting layer 102 away from the substrate 101, and at least part of the shielding layer 103 is located in the border area B1; the orthographic projection of the shielding layer 103 on the substrate 101 overlaps with the orthographic projection of the light-transmitting layer 102 on the substrate 101; wherein the shielding layer 103 is used to shield light with wavelengths in the visible spectrum range and to transmit light with wavelengths in the infrared spectrum range to the light-transmitting layer 102; or, the border area B1 further includes a light adjustment structure 105, which is used to adjust light to the light-transmitting layer 102.

[0047] Specifically, the display panel includes a display area AA, a bezel area B1, and a light-transmitting area B2; the display panel includes a substrate 101, which is, for example, a substrate substrate and has a supporting function; or the substrate 101 is an array substrate and is provided with pixel driving circuitry; the light-transmitting area B2 is provided with blind holes, which can improve the light transmittance of the light-transmitting area B2, and the portion of the light-transmitting layer 102 located in the light-transmitting area B2 fills the blind holes, which can reduce the light reflection phenomenon between the substrate 101 and the gas interface at the blind holes, further increasing the light transmittance of the light-transmitting area B2; a photosensitive device is provided below the substrate 101 corresponding to the light-transmitting area B2, such as a camera. The display area AA may be provided with a pixel circuit layer and a light-emitting device layer (…). Figure 3 and Figure 4(Not shown in the image) A pixel circuit layer is disposed on the substrate 101 to form a pixel driving circuit. Exemplarily, the pixel circuit layer may include multiple metal layers and insulating layers to form transistors, capacitors, and other devices, as well as interconnections between different devices, thereby forming the pixel driving circuit. A light-emitting device layer is disposed on the side of the pixel circuit layer away from the substrate 101 to form a light-emitting device. Exemplarily, the light-emitting device layer may include a stacked anode layer, an organic layer, and a cathode layer. The display area AA also has a pixel definition layer disposed between the pixel circuit layer and the light-emitting device layer to form a pixel definition area, in which a light-emitting device is formed. The border area B1 includes multiple inorganic layers 107, which may include at least one inorganic layer extending from within the display area AA. Exemplarily, the inorganic layer 107 may include metal layers and / or insulating layers from the pixel circuit layer. The border area B1 also includes a shielding layer 103, which can shield external light and light from the display area AA, reducing light interference with the photosensitive device. The display panel also includes an encapsulation layer 104, which covers the display area AA, the bezel area B1, and the light-transmitting area B2. The encapsulation layer 104 may include an inorganic layer, or a stack of inorganic and organic layers, for encapsulating and protecting the display panel. The display panel also includes support pillars 106 for supporting the encapsulation layer 104. The light-transmitting area B2 includes a light-transmitting layer 102 disposed on the substrate 101. The light-transmitting layer 102 can reduce the reflection of light through the light-transmitting area B2, improve the light transmittance of the light-transmitting area B2, and avoid problems such as Newton's rings in the light-transmitting area B2. The light-transmitting layer 102 may include an colloid, such as a UV adhesive, which can be cured by irradiation with appropriate light. The incident direction of the light is, for example, perpendicular to the encapsulation layer 104, which is the X-direction of the film layer stacking of the display panel, thereby fixing the light-transmitting layer 102 and ensuring the stability of the display panel.

[0048] For example, refer to Figure 3 The material of the light-transmitting layer can be a thermosetting adhesive, and the material of the light-shielding layer can be germanium. The shielding layer 103 can block light with wavelengths in the visible spectrum, blocking interference from visible light from the outside and the display area AA on the photosensitive device; the shielding layer 103 can transmit light with wavelengths in the infrared spectrum, so when the light-transmitting layer 102 is cured and irradiated with infrared light, the infrared light can pass through the shielding layer 103 and irradiate the light-transmitting layer 102, thereby irradiating the overlapping area of ​​the light-transmitting layer 102 and the shielding layer 103, so that the entire light-transmitting layer 102 can be irradiated by light, allowing the light-transmitting layer 102 to be completely cured.

[0049] Or, refer to Figure 4The shielding layer 103 is opaque and includes, for example, metal traces. The metal is molybdenum (Mo), which is a light-shielding material and is opaque. A light adjustment structure 105 is provided in the frame area B1. During the curing of the light-transmitting layer 102, the light between the shielding layer 103 and the display area AA can be adjusted by the light adjustment structure 105, for example, by reflection, changing the direction of the light so that the light can shine on the light-transmitting layer 102, thereby illuminating the overlapping area of ​​the light-transmitting layer 102 and the shielding layer 103. The entire light-transmitting layer 102 can be illuminated by light, thereby ensuring that the light-transmitting layer 102 can be completely cured.

[0050] In this embodiment, when the shielding layer is opaque, a light adjustment structure can be provided in the frame area. During the curing of the light-transmitting layer, when light is irradiated onto the light-transmitting layer, the light between the shielding layer and the display area can be adjusted by the light adjustment structure to change the direction of the light, allowing the light to irradiate the light-transmitting layer and the overlapping area of ​​the light-transmitting layer and the shielding layer. The entire light-transmitting layer can be irradiated, thus ensuring complete curing. Alternatively, the shielding layer can block light in the visible spectrum to prevent interference from visible light to the photosensitive device; if the shielding layer is translucent in the infrared spectrum, infrared light can be used to irradiate the light-transmitting layer during thermal curing. The infrared light can pass through the shielding layer and irradiate the overlapping area of ​​the light-transmitting layer and the shielding layer, allowing the light-transmitting layer to be completely cured. This embodiment solves the problem of the light-transmitting layer being blocked and unable to cure, achieving complete curing of the light-transmitting layer.

[0051] Based on the above implementation scheme, optionally, the material of the shielding layer 103 includes germanium.

[0052] Specifically, the shielding layer 103 may include germanium metal traces. Germanium metal is opaque in the visible spectrum, which can block visible light and prevent it from interfering with the photosensitive device. It has a wide transmission range in the infrared band, allowing infrared light to pass through the shielding layer 103. By using germanium material to prepare the shielding layer 103, infrared light can be used to irradiate the light-transmitting layer 102 during the thermosetting of the light-transmitting layer 102. The infrared light can pass through the shielding layer 103 and irradiate the light-transmitting layer 102, thereby irradiating the overlapping area of ​​the light-transmitting layer 102 and the shielding layer 103, and thermosetting the light-transmitting layer 102 below the shielding layer 103 to achieve complete curing of the light-transmitting layer 102.

[0053] Optionally, the light adjustment structure 105 includes at least one right-angle prism 1051, at least part of which is disposed in the same layer as the light-transmitting layer 102 and located on the side of the blocking layer 103 away from the light-transmitting area B3; the hypotenuse of the right-angle prism 1051 is used to reflect light to the light-transmitting layer 102.

[0054] Specifically, after light enters the right-angle prism 1051, it can be reflected by the hypotenuse of the right-angle prism 1051, thus reflecting the light to the light-transmitting layer 102; or it can undergo total internal reflection by the hypotenuse of the right-angle prism 1051, thus reflecting the light to the light-transmitting layer 102 and illuminating the overlapping area of ​​the light-transmitting layer 102 and the blocking layer 103; the entire light-transmitting layer 102 can be illuminated by light, thus ensuring that the light-transmitting layer 102 can be completely cured.

[0055] Figure 5 yes Figure 2 Another sectional view along the C1-C2 direction, Figure 6 yes Figure 5 A magnified view of a portion of the image, optionally, can be referenced. Figure 5 and Figure 6 The display panel also includes: an encapsulation layer 104 disposed on the side of the shielding layer 103 away from the substrate 101; the first right-angle side a of the right-angle prism 1051 is perpendicular to the film stacking direction of the display panel and located away from the substrate 101, and the second right-angle side b of the right-angle prism 1051 is parallel to the film stacking direction of the display panel and connected to the end of the first right-angle side a near the light-transmitting area B2.

[0056] Specifically, the right-angle prism 1051 includes a first right-angled side a, a second right-angled side b, and a hypotenuse. By setting the first right-angled side a of the right-angle prism 1051 to be perpendicular to the film layer stacking direction of the display panel and located on the side away from the substrate 101, and the second right-angled side b of the right-angle prism 1051 to be parallel to the film layer stacking direction of the display panel and connected to the end of the first right-angled side a near the light-transmitting area B2, light is reflected through the hypotenuse of the right-angle prism 1051, that is, the right-angle prism 1051 deflects the incident light and reflects the light to the light-transmitting layer 102, thereby irradiating the light-transmitting layer 102 and irradiating the overlapping area of ​​the light-transmitting layer 102 and the shielding layer 103. The entire light-transmitting layer 102 can be irradiated by light, thereby ensuring that the light-transmitting layer 102 can be completely cured.

[0057] It should be noted that in some other embodiments, the right-angle prism 1051 can be partially on the same layer as the shielding layer 103, and the inclined side of the right-angle prism 1051 can still adjust the light to the light-transmitting layer 102 and solidify the light-transmitting layer 102; when the encapsulation layer 104 is a rigid encapsulation, a groove needs to be provided in the encapsulation layer 104 so that the right-angle prism 1051 can be partially on the same layer as the shielding layer 103.

[0058] Preferably, refer to Figure 6 The first angle θ of the right-angle prism 1051 is greater than or equal to the critical angle for total internal reflection of the incident light; where the first angle θ is the angle opposite to the second right-angle side b.

[0059] Specifically, if the refractive index of right-angle prism 1051 is n1 and the refractive index of air is n2, then the critical angle for total internal reflection of right-angle prism 1051 is... When the first angle θ of the right-angle prism 1051 is greater than or equal to the critical angle of total internal reflection, the right-angle prism 1051 can cause total internal reflection of light, that is, the incident light can be completely reflected to the light-transmitting layer 102, and the incident light between the blocking layer 103 and the display area AA can be completely reflected to the light-transmitting layer 102. This can increase the intensity and quantity of light reflected to the light-transmitting layer 102, thereby achieving a greater degree of illumination of the light-transmitting layer 102, accelerating the curing of the light-transmitting layer 102, and ensuring that the light-transmitting layer 102 can be completely cured.

[0060] For example, the material of the right-angle prism 1051 is optical glass, with a refractive index n1 of 1.5-1.7 and an air refractive index n2 of 1. According to the formula for the critical angle of total internal reflection, the critical angle β of total internal reflection can be determined to be approximately 36°-42°. Thus, the first angle θ of the right-angle prism 1051 can be set to 45°-55°. Since the first angle θ of the right-angle prism 1051 is greater than the critical angle of total internal reflection, total internal reflection can occur, ensuring that light can illuminate the light-transmitting layer 102 to a greater extent.

[0061] or, Figure 7 yes Figure 2 Another sectional view along the C1-C2 direction, Figure 8 yes Figure 7 A magnified view of a portion of the image, optionally, can be referenced. Figure 7 and Figure 8 The first right-angled side a of the right-angled prism 1051 is perpendicular to the film stacking direction of the display panel and is located near the substrate 101. The second right-angled side b of the right-angled prism 1051 is parallel to the film stacking direction of the display panel and is connected to the first end of the first right-angled side a away from the light-transmitting area B2.

[0062] Specifically, by setting the first right-angled side a of the right-angled prism 1051 to be perpendicular to the film layer stacking direction of the display panel and located near the substrate 101, and the second right-angled side b of the right-angled prism 1051 to be parallel to the film layer stacking direction of the display panel and connected to the first end of the first right-angled side a away from the light-transmitting area B2, that is, the second right-angled side b is close to the display area AA, the hypotenuse of the right-angled prism 1051 can directly reflect the incident light; after the light is incident on the right-angled prism 1051, it can be reflected by the hypotenuse of the right-angled prism 1051, so that the light is reflected to the light-transmitting layer 102, thereby illuminating the overlapping area of ​​the light-transmitting layer 102 and the shielding layer 103; the entire light-transmitting layer 102 can be illuminated by light, thereby ensuring that the light-transmitting layer 102 can be completely cured.

[0063] It should be noted that when the first right-angled side a of the right-angled prism 1051 is perpendicular to the film stacking direction of the display panel and located near the substrate 101, and the second right-angled side b of the right-angled prism 1051 is parallel to the film stacking direction of the display panel and connected to the first end of the first right-angled side a away from the light-transmitting area B2, the hypotenuse of the right-angled prism 1051 can directly reflect light, and it is not necessary to limit the size of the first angle θ.

[0064] Optionally, at least one right-angle prism 1051 is disposed around the shielding layer 103.

[0065] Specifically, the right-angle prism 1051 is arranged around the shielding layer 103, that is, the orthographic projection of at least one right-angle prism 1051 on the substrate 101 surrounds the orthographic projection of the shielding layer 103 on the substrate 101; for example, when the right-angle prism 1051 is small in size or few in number, the right-angle prism 1051 partially surrounds the shielding layer 103; the right-angle prism 1051 can reflect part of the light to the light-transmitting layer 102, illuminating part of the overlapping area between the light-transmitting layer 102 and the shielding layer 103, thereby increasing the curing area of ​​the light-transmitting layer 102; and when the right-angle prism 1051 partially surrounds the shielding layer 103, it can prevent the light-transmitting layer 102 from flowing outward when it is not cured; it can also expel the air bubbles generated when pressing the light-transmitting layer 102 during the pressing and fixing of the display panel, thereby achieving the effect of assisting in air venting and making the pressing of the light-transmitting layer 102 more uniform. When the right-angled prism 1051 is large in volume or numerous, the right-angled prism 1051 can completely surround the shielding layer 103. The right-angled prism 1051 can reflect all the light between the shielding layer 103 and the display area AA to the light-transmitting layer 102, thereby illuminating the overlapping area of ​​the light-transmitting layer 102 and the shielding layer 103. The entire light-transmitting layer 102 can be illuminated by light, ensuring that the light-transmitting layer 102 can be completely cured. It can also prevent the light-transmitting layer 102 from flowing outward before curing, thus preventing the light-transmitting layer 102 from overflowing.

[0066] For example, Figure 9 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, for reference. Figure 9The display panel includes a right-angle prism 1051. The right-angle prism 1051 is relatively small in size and partially surrounds the shielding layer 103. The right-angle prism 1051 can reflect some light to the light-transmitting layer 102, illuminating part of the overlapping area between the light-transmitting layer 102 and the shielding layer 103, thereby increasing the curing area of ​​the light-transmitting layer 102. Furthermore, the right-angle prism 1051 can prevent the light-transmitting layer 102 from flowing outward when it is not cured. It can also expel air bubbles generated during the pressing and fixing of the display panel, thereby assisting in the degassing effect and making the pressing of the light-transmitting layer 102 more uniform. The display panel may also include two right-angle prisms 1051, which partially surround the shielding layer 103. These prisms can reflect some light to the light-transmitting layer 102, illuminating the overlapping area of ​​the light-transmitting layer 102 and the shielding layer 103, thereby increasing the curing area of ​​the light-transmitting layer 102. Furthermore, the gap between the two right-angle prisms 1051 can prevent the light-transmitting layer 102 from flowing outward before curing. Additionally, during the pressing and fixing of the display panel, air bubbles generated during the pressing of the light-transmitting layer 102 can be expelled, achieving the effect of assisting in air venting and making the pressing of the light-transmitting layer 102 more uniform. Figure 9 The example shown is only a right-angle prism 1051, but it is not limited.

[0067] or, Figure 10 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, for reference. Figure 10 The display panel includes a right-angle prism 1051. The right-angle prism 1051 is relatively large and is set completely around the shielding layer 103. The right-angle prism 1051 can reflect all the light between the shielding layer 103 and the display area AA to the light-transmitting layer 102, thereby illuminating the overlapping area of ​​the light-transmitting layer 102 and the shielding layer 103. The entire light-transmitting layer 102 can be illuminated, ensuring that the light-transmitting layer 102 can be completely cured. When the right-angle prism 1051 is completely around the shielding layer 103, it can not only reflect light to the light-transmitting layer 102, but also prevent the light-transmitting layer 102 from flowing outward before curing, thus preventing the light-transmitting layer 102 from overflowing.

[0068] Optionally, Figure 11 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, for reference. Figure 11 The light adjustment structure 105 includes a plurality of right-angle prisms 1051, which are spaced apart around the periphery of the shielding layer 103.

[0069] Specifically, the light adjustment structure 105 may include multiple right-angled prisms 1051, which partially surround the shielding layer 103. That is, the orthographic projection of the multiple right-angled prisms 1051 onto the substrate 101 surrounds the orthographic projection of the shielding layer 103 onto the substrate 101. This allows all light between the shielding layer 103 and the display area AA to be reflected to the light-transmitting layer 102, thereby illuminating the overlapping area of ​​the light-transmitting layer 102 and the shielding layer 103. The entire light-transmitting layer 102 can be illuminated, ensuring complete curing. The multiple right-angled prisms 1051 partially surrounding the shielding layer 103 also prevent the light-transmitting layer 102 from flowing outwards before curing. Furthermore, the multiple right-angled prisms 1051 are spaced apart, which can expel air bubbles generated during the pressing and fixing of the display panel, achieving an air venting effect and making the pressing of the light-transmitting layer 102 more uniform.

[0070] Furthermore, when multiple right-angle prisms 1051 are spaced apart, they can be evenly distributed or non-uniformly distributed; that is, the interval between two adjacent right-angle prisms 1051 can be the same or different, and the specific size of the interval can be determined according to the actual situation, and is not limited here.

[0071] Figure 12 yes Figure 2 Another sectional view along the C1-C2 direction, Figure 13 yes Figure 10 A magnified view of a portion of the image, optionally, can be referenced. Figure 12 and Figure 13 The display panel further includes: an encapsulation layer 104 disposed on the side of the shielding layer 103 away from the substrate 101; a frame area B1 is also provided with at least one support pillar 106, at least part of the support pillar 106 is disposed on the same layer as the light-transmitting layer 102 and is located on the side of the shielding layer 103 away from the light-transmitting area B3; the light adjustment structure 105 includes a reflective layer 1052, the reflective layer 1052 is disposed on the side of the support pillar 106 near the light-transmitting area, and the included angle δ between the reflective layer 1052 and the encapsulation layer 104 near the light-transmitting area B3 is less than 90°.

[0072] Specifically, the light adjustment structure 105 may also include a reflective layer 1052. The reflective layer 1052 may be prepared by silver plating on the support pillar 106, for example. The angle δ between the reflective layer 1052 and the encapsulation layer 104 near the light-transmitting layer 102 is less than 90°. When the light-transmitting layer 102 is cured, the incident light can be reflected by the reflective layer 1052 to the light-transmitting layer 102 and irradiate the overlapping area of ​​the light-transmitting layer 102 and the shielding layer 103, thereby achieving a greater degree of irradiation of the light-transmitting layer 102, which can accelerate the curing of the light-transmitting layer 102 and ensure that the light-transmitting layer 102 can be completely cured.

[0073] It should be noted that in some other embodiments, the support column 106 can be partially on the same layer as the shielding layer 103, that is, the reflective layer 1052 can be partially on the same layer as the shielding layer 103. The reflective layer 1052 can still reflect light to the light-transmitting layer 102 and cure the light-transmitting layer 102. When the encapsulation layer 104 is a rigid encapsulation, a groove needs to be provided in the encapsulation layer 104 so that the support column 106 can be partially on the same layer as the shielding layer 103.

[0074] Optionally, at least one support column 106 is disposed around the shielding layer 103.

[0075] Specifically, the support pillars 106 are arranged around the shielding layer 103, that is, the orthographic projection of at least one support pillar 106 on the substrate 101 surrounds the orthographic projection of the shielding layer 103 on the substrate 101; that is, the reflective layer 1052 is arranged at least partially around the shielding layer 103. When the support pillars 106 are large in volume or numerous, the reflective layer 1052 is also large in volume or numerous. The reflective layer 1052 can completely surround the shielding layer 103. The reflective layer 1052 can reflect all the light between the shielding layer 103 and the display area AA to the light-transmitting layer 102, thereby illuminating the overlapping area of ​​the light-transmitting layer 102 and the shielding layer 103; the entire light-transmitting layer 102 can be illuminated by light, ensuring that the light-transmitting layer 102 can be completely cured; it can also prevent the light-transmitting layer 102 from flowing outward when it is not cured, thus preventing the light-transmitting layer 102 from overflowing. When the support pillars 106 are small in size or few in number, the reflective layer 1052 is also small in size or few in number. The reflective layer 1052 can partially surround the shielding layer 103. The reflective layer 1052 can reflect some light to the light-transmitting layer 102, illuminating the overlapping area of ​​the light-transmitting layer 102 and the shielding layer 103, thereby increasing the curing area of ​​the light-transmitting layer 102. Furthermore, when the reflective layer 1052 partially surrounds the shielding layer 103, it can prevent the light-transmitting layer 102 from flowing outward before curing. It can also expel air bubbles generated during the pressing and fixing of the display panel, thereby assisting in the air venting effect and making the pressing of the light-transmitting layer 102 more uniform.

[0076] For example, Figure 14 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, for reference. Figure 14The frame area B1 is provided with a support column 106, that is, the frame area B1 includes a reflective layer 1052. The reflective layer 1052 is small in volume and partially surrounds the shielding layer 103. It can reflect some light to the light-transmitting layer 102 and illuminate the overlapping area of ​​the light-transmitting layer 102 and the shielding layer 103, thereby increasing the curing area of ​​the light-transmitting layer 102. In addition, the reflective layer 1052 can prevent the light-transmitting layer 102 from flowing outward when it is not cured. It can also expel the air bubbles generated when pressing the light-transmitting layer 102 during the pressing and fixing of the display panel, thereby achieving the effect of assisting in air venting and making the pressing of the light-transmitting layer 102 more uniform. The frame area B1 can also be provided with two support pillars 106, that is, the frame area B1 includes two reflective layers 1052. The two reflective layers 1052 partially surround the shielding layer 103, which can reflect some light to the light-transmitting layer 102 and illuminate the overlapping area of ​​the light-transmitting layer 102 and the shielding layer 103, thereby increasing the curing area of ​​the light-transmitting layer 102. In addition, the gap between the two reflective layers 1052 can prevent the light-transmitting layer 102 from flowing outward when it is not cured. It can also expel the air bubbles generated when pressing the light-transmitting layer 102 during the pressing and fixing of the display panel, thereby achieving the effect of assisting in air venting and making the pressing of the light-transmitting layer 102 more uniform. Figure 9 The example only shows the case of setting one reflective layer 1052, but does not limit it.

[0077] or, Figure 15 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, for reference. Figure 13 The frame area B1 is provided with at least one annular support column 106, which completely surrounds the shielding layer 103; that is, the reflective layer 1052 completely surrounds the shielding layer 103. The reflective layer 1052 can reflect all the light between the shielding layer 103 and the display area AA to the light-transmitting layer 102, thereby illuminating the overlapping area of ​​the light-transmitting layer 102 and the shielding layer 103; the entire light-transmitting layer 102 can be illuminated by light, ensuring that the light-transmitting layer 102 can be completely cured; when the reflective layer 1052 completely surrounds the shielding layer 103, it can not only reflect light to the light-transmitting layer 102, but also prevent the light-transmitting layer 102 from flowing outward before curing, thus preventing the light-transmitting layer 102 from overflowing.

[0078] Optionally, Figure 16 This is a schematic diagram of another display panel structure provided in an embodiment of the present invention, for reference. Figure 16 The border area B1 is provided with multiple support columns 106, which are spaced around the periphery of the shielding layer 103.

[0079] Specifically, the frame area B1 is provided with multiple support pillars 106, which are spaced apart around the periphery of the shielding layer 103. That is, the orthographic projection of the multiple support pillars 106 on the substrate 101 surrounds the orthographic projection of the shielding layer 103 on the substrate 101. The light adjustment structure 105 may include multiple reflective layers 1052, which partially surround the shielding layer 103. They can reflect all the light between the shielding layer 103 and the display area AA to the light-transmitting layer 102, thereby illuminating the overlapping area of ​​the light-transmitting layer 102 and the shielding layer 103. The entire light-transmitting layer 102 can be illuminated by light, ensuring that the light-transmitting layer 102 can be completely cured. The multiple reflective layers 1052 partially surround the shielding layer 103, which can also prevent the light-transmitting layer 102 from flowing outward before curing. Furthermore, the multiple reflective layers 1052 are spaced apart, which can expel the air bubbles generated during the pressing and fixing of the display panel, thereby assisting in the air venting effect and making the pressing of the light-transmitting layer 102 more uniform.

[0080] Furthermore, when multiple reflective layers 1052 are spaced apart, they can be evenly distributed or non-uniformly distributed; that is, the spacing between two adjacent reflective layers 1052 can be the same or different, and the specific size of the spacing can be determined according to the actual situation, and is not limited here.
