Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present disclosure, unless otherwise specified, "plurality" means two or more.
[0046] When describing some embodiments, the expressions "coupled" and "connected" and their derivatives may be used. The term "connected" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. The term "coupled" indicates, for example, that two or more components are in direct physical or electrical contact. The term "coupled" or "communicatively coupled" may also refer to two or more components that are not in direct contact with each other, but still cooperate or interact with each other.

[0047] “At least one of A, B and C” has the same meaning as “at least one of A, B or C” and both include the following combinations of A, B and C: A only, B only, C only, the combination of A and B, the combination of A and C, the combination of B and C, and the combination of A, B and C.
[0048] “A and / or B” includes the following three combinations: A only, B only, and a combination of A and B.
[0049] As used herein, "about," "substantially," or "approximately" includes the stated value and an average value that is within an acceptable range of deviation from the particular value as determined by one of ordinary skill in the art taking into account the measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system).

[0051] It will be understood that when a layer or element is referred to as being on another layer or substrate, it can be directly on the other layer or substrate, or intervening layers may be present therebetween.
[0052] Exemplary embodiments are described herein with reference to cross-sectional and / or plan views that are idealized exemplary drawings. In the drawings, the thickness of layers and the area of regions are exaggerated for clarity. Therefore, variations in shape relative to the drawings due to, for example, manufacturing techniques and / or tolerances are contemplated. Therefore, the exemplary embodiments should not be construed as limited to the shapes of the regions shown herein, but rather include deviations in shape due to, for example, manufacturing. For example, an etched region shown as a rectangle will typically have curved features. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to illustrate the actual shape of regions of the device and are not intended to limit the scope of the exemplary embodiments.
[0053] With the development of AMOLED (Active-matrix Organic Light Emitting Diode) screens, the demand for screen light output effect, power consumption and thickness reduction has made COE (Color Film On Encapsulation, that is, making the color film directly on the encapsulation layer) technology gradually become a mainstream terminal device requirement.
[0054] COE technology uses color filters instead of external polarizers, significantly reducing production costs and providing greater productivity. Furthermore, AMOLEDs using COE technology offer higher light extraction efficiency and improved bending resistance, meeting product performance requirements.
[0055] Typically, if Figure 1 As shown, the display device 1000 ′ includes a display panel 100 ′ and other electronic components, such as a camera, etc. The display panel 100 ′ includes a display area AA and at least one opening area H, and the electronic components are arranged in the holes of the opening area H.
[0056] However, in COE technology, due to the lack of polarizer obstruction, the SCF (Super Clean Foam) composite film will be offset when attached to the screen opening area H. At the same time, due to the high light reflectivity in the area surrounding the opening area H, light leaks from the screen opening area H and a white edge appears, causing abnormal display around the screen opening area H. If BM (Black Matrix) is used to completely block the area surrounding the screen opening area H, although the light leakage problem can be effectively improved, since the area surrounding the screen opening area H is completely blocked, the EAC (Even After Cutting, changing the rigid glass backplane to a flexible product) process section and the module process section cannot meet the requirements of rainbow pattern detection.
[0057] It should be noted that both the EAC and module processes use a method of illuminating the product with a light source and detecting the rainbow pattern by receiving the reflected light. Because the BM layer is opaque, the BM coverage method will affect the success rate of rainbow pattern detection.
[0058] Based on this, Figure 2 As shown, some embodiments of the present disclosure provide a display panel 100, which includes: a display area AA, at least one opening area H, and a hole edge area F located between the opening area H and the display area AA, and the hole edge area F at least partially surrounds the opening area H.
[0059] In some examples, such as Figure 2 As shown, the display panel 100 includes an aperture area H. The aperture area H is, for example, circular or substantially circular such as an elliptical shape. The area between the aperture area H and the display area AA is a hole edge area F. The hole edge area F surrounds the aperture area H, meaning that the hole edge area F surrounds the aperture area H in a circle, and the display area AA surrounds the hole edge area F and the aperture area H. There may be multiple aperture areas H, each of which is surrounded by a hole edge area F. The number of aperture areas H is set as needed and is not limited here.
[0060] like Figure 3 As shown, the aperture edge region F includes: a first isolation region F1, an encapsulation region F2, and a second isolation region F3 arranged in sequence along a first direction X. The first direction X is the direction from the aperture region H to the display region AA. The display panel 100 includes: a substrate 1 and a light shielding layer 403 arranged on one side of the substrate 1.
[0061] It should be noted that Figure 3 and Figure 6 are cross-sectional views obtained along a cross-sectional line of the display panel 100 of the two structures respectively. Figure 3 and Figure 6 The position of the corresponding cross-section line in the display panel 100 is Figure 2The position of the cross-section line BB in the display panel 100 is shown to be the same.
[0062] For example, Figure 4 As shown, the first isolation region F1 , the packaging region F2 and the second isolation region F3 are annular structures surrounding the opening region H.
[0063] It should be noted that Figure 4 、 Figure 7 and Figure 10 are enlarged views of the display panels 100 of the three structures at one position, Figure 4 、 Figure 7 and Figure 10 The position in the display panel 100 is Figure 2 The position of C in the display panel 100 shown in FIG. 1 is the same.
[0064] It should be noted that, in order to clearly show the design of the light shielding layer 403 in the hole edge area F, Figure 4 and the following Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 In the example, the structure of the light shielding layer 403 is mainly used, and the design of other film layers can refer to Figure 3 、 Figure 6 and Figure 12 The cross-sectional view shown.
[0065] It is understandable that the substrate 1 has openings in the opening area H. Electronic devices, such as optical sensors, can be placed at the openings of the display panel 100. Therefore, the openings in the opening area H can penetrate the substrate 1, resulting in higher light transmittance.
[0066] For example, the substrate 1 may be a single-layer structure or a multi-layer structure. Figure 3 As shown, the substrate 1 may include a glass layer 101, a flexible base layer 102, and a waterproof layer 103 stacked in sequence. The flexible base layer 102 may be made of polyimide, and the waterproof layer 103 may be made of silicon nitride.
[0067] Exemplarily, the light shielding layer 403 includes BM (Black Matrix).
[0068] For example, Figure 3 、 Figure 6 and Figure 12As shown, the hole edge region F also includes a cutting line region F0 disposed near the first isolation region F1 and the opening region H. Cutting is performed at the boundary line L3 of the cutting line region F0 near the opening region H to form the opening region H for placing electronic components. Exemplarily, the size of the cutting line region F0 in the first direction X ranges from 10 μm to 20 μm.
[0069] Among them, such as Figure 3 、 Figure 6 and Figure 12 As shown, the ratio of the orthographic projection area of the portion of the light shielding layer 403 located in the first isolation region F1, the packaging region F2 and the second isolation region F3 on the substrate 1 to the sum of the areas of the first isolation region F1, the packaging region F2 and the second isolation region F3 is in the range of 30% to 62%.
[0070] For example, Figure 3 As shown, the ratio of the orthographic projection area of the portion of the light-shielding layer 403 located in the first isolation region F1, the packaging region F2 and the second isolation region F3 on the substrate 1 to the sum of the areas of the first isolation region F1, the packaging region F2 and the second isolation region F3 is 30%, 40%, 50%, 55%, 60% or 62%, etc., which is not limited here.
[0071] It should be noted that the first isolation region F1 , the encapsulation region F2 and the second isolation region F3 have different film layer structures. Please refer to the subsequent content for details, which will not be described here in detail.
[0072] That is, the light shielding layer 403 is provided in the first isolation region F1 , the encapsulation region F2 , and the second isolation region F3 , but the light shielding layer 403 does not completely cover the first isolation region F1 , the encapsulation region F2 , and the second isolation region F3 .
[0073] By setting a shading layer 403 around the opening area H, that is, the hole edge area F, and the shading layer 403 does not completely cover the first isolation area F1, the packaging area F2 and the second isolation area F3, the ratio of the positive projection area of the light shading layer 403 on the substrate 1 to the sum of the areas of the first isolation area F1, the packaging area F2 and the second isolation area F3 is in the range of 30% to 62%. This design can effectively reduce the reflection of light in the hole edge area H and improve the white edge problem caused by light leakage. At the same time, the area where the shading layer 403 is not set can meet the needs of rainbow pattern detection.
[0074] In some embodiments, as Figure 3 、 Figure 6 and Figure 12 As shown, the first isolation region F1 includes a first light shielding layer removal region Fa, which is disposed on a side of the first isolation region F1 close to the opening region H. The light shielding layer 403 is not disposed in the first light shielding layer removal region Fa.
[0075] For example, Figure 4 As shown, the first light shielding layer removal area Fa is an annular structure arranged around the opening area H.
[0076] For example, the light shielding layer 403 in the area of the first isolation region F1 close to the opening region H is removed, that is, the light shielding layer 403 is not provided in this area, thereby forming a first light shielding layer removed area Fa. The first light shielding layer removed area Fa is not blocked by the light shielding layer 403. For example, Figure 5 As shown, the first light-shielding layer removal area Fa is not provided with a light-shielding layer 403 on the side close to the opening area H, that is, the cutting line area F0 is not provided with a light-shielding layer 403. The first light-shielding layer removal area Fa and the cutting line area F0 are collectively referred to as the first region M1. The first region M1 is not provided with a light-shielding layer 403. Therefore, the first region M1 can be used for rainbow pattern detection.
[0077] In some embodiments, as Figure 3 As shown, a dimension d1 of the first light shielding layer removal area Fa along the first direction X ranges from 10 μm to 25 μm.
[0078] For example, Figure 3 As shown, the size d1 of the first light shielding layer removal area Fa along the first direction X is 10 μm, 13 μm, 15 μm, 18 μm, 20 μm, 23 μm or 25 μm, etc., which is not limited here.
[0079] That is, the size of the first light shielding layer removal area Fa along the radial direction of the opening area H ranges from 10 μm to 25 μm.
[0080] By setting a first light shielding layer removal area Fa with a dimension d1 ranging from 10 μm to 25 μm along the first direction X on the side of the first isolation area F1 close to the opening area H, the white edge problem caused by light leakage in the hole edge area F can be avoided while providing conditions for rainbow pattern detection.
[0081] In some embodiments, as Figure 3 、 Figure 6 and Figure 12 As shown, the first isolation region F1 includes: a plurality of first isolation pillars 50 spaced apart in the first direction X, each of the plurality of first isolation pillars 50 surrounding the opening region H. The first isolation region F1 includes: a first light-shielding layer-removed region Fa, the first light-shielding layer-removed region Fa covering the orthographic projection of one of the plurality of first isolation pillars 50 near the opening region H on the substrate 1.
[0082] For example, Figure 3 and Figure 5As shown, multiple first isolation pillars 50 are spaced apart radially along the opening region H. In other words, the multiple first isolation pillars 50 are annular structures surrounding the opening region H, and the diameters of the multiple first isolation pillars 50 increase sequentially. Providing multiple first isolation pillars 50 in the first isolation region F1 can improve the packaging capability of the hole edge region F and help isolate it from water vapor erosion.
[0083] For example, Figure 3 and Figure 5 As shown, along the first direction X, seven first isolation pillars 50 are provided in the first isolation region F1, and a first isolation pillar 50 close to the opening region H is the seventh first isolation pillar 507. That is, the first light shielding layer removal region Fa covers the orthographic projection of the seventh first isolation pillar 50 on the substrate 1.
[0084] That is to say, no light shielding layer 403 is provided on the side of the seventh first isolation column 507 away from the substrate 1 .
[0085] In some embodiments, as Figures 3 to 5 As shown, the first isolation region F1 includes a second light-shielding layer-removed region Fb, which is located on a side of the first isolation region F1 close to the encapsulation region F2. The second isolation region F3 includes a third light-shielding layer-removed region Fc, which is located on a side of the second isolation region F3 close to the encapsulation region F2. The second light-shielding layer-removed region Fb, the encapsulation region F2, and the third light-shielding layer-removed region Fb are not provided with a light-shielding layer 403. The second light-shielding layer-removed region Fb, the encapsulation region F2, and the third light-shielding layer-removed region Fb are sequentially connected in the first direction X.
[0086] For example, Figure 4 As shown, the second light shielding layer removal area Fb and the third light shielding layer removal area Fc are both annular structures arranged around the opening area H.
[0087] For example, Figures 3 to 5 As shown, the light shielding layer 403 is removed from the area on one side of the first isolation region F1 near the encapsulation region F2, i.e., no light shielding layer 403 is provided in this area, forming a second light shielding layer removed area Fb. The second light shielding layer removed area Fb is not blocked by the light shielding layer 403 and can be used for rainbow pattern detection.
[0088] The light shielding layer 403 is removed from the area on one side of the second isolation region F3 near the encapsulation region F2, i.e., no light shielding layer 403 is provided in this area, forming a third light shielding layer-removed region Fc. The third light shielding layer-removed region Fc is not blocked by the light shielding layer 403 and can be used for rainbow pattern detection. The light shielding layer 403 is not provided in the encapsulation region F2, i.e., the encapsulation region F2 is not blocked by the light shielding layer 403 and can be used for rainbow pattern detection.
[0089] For example, Figure 5As shown, the second light-shielding layer removal area Fb, the encapsulation area F2, and the third light-shielding layer removal area Fb are sequentially connected in the first direction X. That is, the second light-shielding layer removal area Fb is provided on one side of the encapsulation area F2 along the second direction Y, and the third light-shielding layer removal area Fc is provided on the other side of the encapsulation area F2 along the second direction Y, wherein the second direction Y is a direction surrounding the opening area H. The second light-shielding layer removal area Fb, the encapsulation area F2, and the third light-shielding layer removal area Fc form a whole second area M2 that is not covered by the light-shielding layer 403. The second area M2 can be used for rainbow pattern detection.
[0090] In some embodiments, as Figure 3 As shown, the sum of the dimensions of the second light shielding layer removal area Fb, the encapsulation area F2 and the third light shielding layer removal area Fc in the first direction X (the sum of the dimensions is expressed as d2) is greater than or equal to 60 μm, that is, d2 ≥ 60 μm.
[0091] For example, the sum of the dimensions d2 of the second light-shielding layer-removed area Fb, the encapsulation area F2, and the third light-shielding layer-removed area Fc in the first direction X is 60 μm, 62 μm, 65 μm, 68 μm, 70 μm, etc., although this is not a limitation. That is, the dimension of the second area M2 for rainbow pattern detection in the first direction X is greater than or equal to 60 μm.
[0092] When the sum d2 of the sizes of the second light-shielding layer removed area Fb, the encapsulation area F2 and the third light-shielding layer removed area Fc in the first direction X is greater than or equal to 60 μm, it can be ensured that the area meets the requirements of rainbow stripe detection.
[0093] In some embodiments, as Figure 3 As shown, the dimension d3 of the second light-shielding layer-removed area Fb in the first direction X ranges from 3 μm to 7 μm, i.e., 7 μm ≥ d3 ≥ 3 μm. The dimension d4 of the third light-shielding layer-removed area Fc in the first direction X ranges from 30 μm to 60 μm, i.e., 60 μm ≥ d4 ≥ 30 μm. The dimension d5 of the encapsulation area F2 in the first direction X ranges from 40 μm to 60 μm, i.e., 60 μm ≥ d5 ≥ 40 μm.
[0094] Exemplarily, a size d3 of the second light shielding layer removal area Fb in the first direction X is 3 μm, 4 μm, 5 μm, 6 μm or 7 μm, etc., which is not limited here.
[0095] By setting the size of the second light shielding layer removal area Fb in the first direction X to be in the range of 3 μm to 7 μm, it can be ensured that the size of the second region M2 in the first direction X meets the requirements of rainbow pattern detection.
[0096] like Figure 3As shown, the first isolation column 50 in the first isolation region F1 near the packaging region F2 is called the first first isolation column 501, and the second light-shielding layer removal region Fb is near the boundary line L1 of the first first isolation column 501, and the spacing d6 between the second light-shielding layer removal region Fb and the first first isolation column 501 in the first direction X is greater than or equal to 6μm, that is, d6 ≥ 6μm. This setting can prevent the light-shielding layer 403 in the first isolation region F1 from falling off. That is, by setting the size range of the second light-shielding layer removal region Fb in the first direction X to 3μm to 7μm, while ensuring that the requirements of rainbow pattern detection are met, it can be ensured that the second light-shielding layer removal region Fb is near the boundary line L1 of the first first isolation column 501, and the spacing d6 between the second light-shielding layer removal region Fb and the first first isolation column 501 in the first direction X is greater than or equal to 6μm, thereby avoiding the problem of the light-shielding layer 403 in the first isolation region F1 falling off.
[0097] Exemplarily, a size d4 of the third light shielding layer removal area Fc in the first direction X is 30 μm, 35 μm, 40 μm, 45 μm, 50 μm or 60 μm, etc., which is not limited here.
[0098] By setting the size d4 of the third light shielding layer removal area Fc in the first direction X to be in the range of 30 μm to 60 μm, the problem of the light shielding layer 403 in the second isolation area F3 falling off can be avoided while meeting the requirements of rainbow fringe detection.
[0099] Exemplarily, a dimension d5 of the encapsulation region F2 in the first direction X is 40 μm, 45 μm, 50 μm, 55 μm, or 60 μm, etc., which is not limited here.
[0100] By setting the dimension d5 of the packaging area F2 in the first direction X to be in the range of 40μm to 60μm, and respectively setting the third shading layer removal area Fc and the second shading layer removal area Fb on both sides of the packaging area F2 along the second direction Y, and the dimension d3 of the second shading layer removal area Fb in the first direction X to be in the range of 3μm to 7μm, and the dimension d4 of the third shading layer removal area Fc in the first direction X to be in the range of 30μm to 60μm, it is effectively ensured that the dimension d2 of the second area M2 in the first direction X where the shading layer 403 is not set is greater than or equal to 60μm, so that the design of the shading layer 403 in the hole edge area F meets the requirements of rainbow pattern detection.
[0101] In some embodiments, as Figure 6 As shown, the light shielding layer 403 is provided with a plurality of first light-transmitting holes K1 in the portion located in the first isolation region F1, the encapsulation region F2, and the second isolation region F3. The plurality of first light-transmitting holes K1 are arranged in an array along the first direction X and the second direction Y. The second direction Y is a direction surrounding the opening region H.
[0102] For example, Figure 6 and Figure 7 As shown, the first light-transmitting hole K1 is a light-transmitting area formed by removing part of the light-shielding layer 403 on the entire light-shielding layer 403. For example, the light-shielding layer 403 is removed in an array arrangement on the entire light-shielding layer 403 to form a light-shielding layer 403 provided with the first light-transmitting holes K1 arranged in an array.
[0103] For example, Figure 6 As shown, the first direction X and the second direction Y are perpendicular to each other.
[0104] By arranging a plurality of first light-transmitting holes K1 in an array on the light-shielding layer 403 of the first isolation region F1 , the packaging region F2 and the second isolation region F3 , the design of the light-shielding layer 403 in the hole edge region F meets the requirements of rainbow pattern detection.
[0105] For example, Figure 8 As shown, the light-shielding layer 403 having a plurality of first light-transmitting holes K1 and located in the first isolation region F1, the packaging region F2 and the second isolation region F3 has a ratio of an orthographic projection area on the substrate 1 to the sum of the areas of the first isolation region F1, the packaging region F2 and the second isolation region F3 in a range of 30% to 62%.
[0106] In some embodiments, as Figure 6 As shown, the size d7 of the region where the plurality of first light-transmitting holes K1 are provided on the light-shielding layer 403 in the first direction X ranges from 150 μm to 600 μm.
[0107] That is to say, if Figure 6 As shown, in the first isolation region F1, the packaging region F2 and the second isolation region F3, the first light-transmitting hole K1 is not set in the entire area of the first isolation region F1, the packaging region F2 and the second isolation region F3 connected in sequence. For example, a first light-shielding layer removal area Fa is set in the first isolation region F1, and multiple first light-transmitting holes K1 are set on the light-shielding layer 403 in the area of the first isolation region F1, the packaging region F2 and the second isolation region F3 and the first light-shielding layer removal area Fa is removed. This area is identified as the third area M3.
[0108] Illustratively, a size d7 of a region of the light shielding layer 403 where the plurality of first light transmission holes K1 are provided in the first direction X is 150 μm, 180 μm, 220 μm, 270 μm, 350 μm, 420 μm, 500 μm or 600 μm, etc., which is not limited here.
[0109] In some embodiments, as Figure 9As shown, the size d8 of each first light-transmitting hole K1 in the plurality of first light-transmitting holes K1 ranges from 15 μm to 40 μm, i.e., 40 μm ≥ d8 ≥ 15 μm. The spacing d9 between each adjacent first light-transmitting hole K1 in the plurality of first light-transmitting holes K1 in the first direction X ranges from 15 μm to 40 μm, i.e., 40 μm ≥ d9 ≥ 15 μm. The spacing d10 between each adjacent first light-transmitting hole K1 in the second direction Y ranges from 15 μm to 40 μm, i.e., 40 μm ≥ d10 ≥ 15 μm.
[0110] Exemplarily, the shape of the first light transmission hole K1 includes either a square or a circle. For example, the first light transmission hole K1 may be square along its axial direction, with the side length d8 of the first light transmission hole K1 ranging from 15 μm to 40 μm. Alternatively, the first light transmission hole K1 may be circular along its axial direction, with the diameter d8 of the first light transmission hole K1 ranging from 15 μm to 40 μm. The shape of the first light transmission hole K1 including either a square or a circle is merely an example and does not limit the shape of the first light transmission hole K1. The first light transmission hole K1 may also have other shapes.
[0111] Exemplarily, the size d8 of the first light-transmitting hole K1 is 15 μm, 20 μm, 25 μm, 30 μm, 35 μm or 40 μm, etc., which is not limited here.
[0112] For example, the distance d9 between two adjacent first light-transmitting holes K1 in the first direction X is 15 μm, 20 μm, 25 μm, 30 μm, 35 μm or 40 μm, etc., which is not limited here.
[0113] For example, the distance d10 between two adjacent first light-transmitting holes K1 in the second direction Y is 15 μm, 20 μm, 25 μm, 30 μm, 35 μm or 40 μm, etc., which is not limited here.
[0114] By designing the size d8 of the first light-transmitting holes K1 and the distance d9 between two adjacent first light-transmitting holes K1 in the first direction X and the distance d10 in the second direction Y, the design of the light-shielding layer 403 in the hole edge area F meets the requirements of rainbow pattern detection.
[0115] In some embodiments, as Figure 10 and Figure 11 As shown, a light shielding layer bridge region M4 is provided between the first isolation region F1 and the second isolation region F3. The portion of the light shielding layer M4 located in the light shielding layer bridge region M4 includes connecting bridges Q1 and second light-transmitting holes K2 alternately arranged in a second direction Y. The second direction Y is a direction surrounding the opening region H.
[0116] like Figure 12As shown, the light shielding layer bridge region M4 covers the encapsulation region F2 and a first portion F11 of the first isolation region F1 close to the encapsulation region F2 , and a second portion F31 of the second isolation region F3 close to the encapsulation region F2 .
[0117] For example, Figure 10 As shown, the second light-transmitting hole K2 is a light-transmitting area formed by removing part of the light-shielding layer 403 .
[0118] For example, Figure 11 As shown, the connecting bridges Q1 and the second light-transmitting holes K2 are alternately arranged to form a ring-shaped light-shielding layer bridging area M4, which is arranged around the opening area H. The connecting bridge Q1 of the light-shielding layer bridging area M4 connects the light-shielding layer 403 of the first isolation area F1 and the light-shielding layer 403 of the second isolation area F3.
[0119] It should be noted that Figure 10 The connecting bridge Q1 and the second light-transmitting hole K2 in Figure 11 The connecting bridge Q1 and the second light-transmitting hole K2 are not drawn in the same size as the example, for example, Figure 10 The connecting bridge Q1 and the second light-transmitting hole K2 are obviously larger than Figure 11 The sizes of the connecting bridge Q1 and the second light-transmitting hole K2 are large. This example does not limit the sizes of the connecting bridge Q1 and the second light-transmitting hole K2, but is only used to more clearly illustrate the positional relationship between the various structures.
[0120] By setting a light shielding layer bridge region M4 between the first isolation region F1 and the second isolation region F3 and providing a second light-transmitting hole K2 in the light shielding layer bridge region M4, the design of the light shielding layer 403 in the hole edge region F meets the requirements of rainbow pattern detection.
[0121] For example, Figure 10 As shown, the ratio of the orthographic projection area of the portion of the light-shielding layer 403 having multiple second light-transmitting holes K2 and located in the first isolation region F1, the packaging region F2 and the second isolation region F3 on the substrate 1 to the sum of the areas of the first isolation region F1, the packaging region F2 and the second isolation region F3 is in the range of 30% to 62%.
[0122] For example, Figure 12 As shown, the light shielding layer bridge area M4 includes three parts connected in sequence: a first part F11, a packaging area F2 and a second part F31, that is, the packaging area F2 and its two sides along the second direction Y are set as the light shielding layer bridge area M4.
[0123] In some embodiments, as Figure 12 As shown, a dimension d14 of the first portion F11 in the first direction X ranges from 3 μm to 7 μm. A dimension d15 of the second portion F31 in the first direction X ranges from 30 μm to 60 μm.
[0124] Exemplarily, a dimension d14 of the first portion F11 in the first direction X is 3 μm, 4 μm, 5 μm, 6 μm, or 7 μm, etc., which is not limited here.
[0125] For example, Figure 12 As shown, by setting the size d14 of the first portion F11 in the first direction X to be in the range of 3μm to 7μm, this setting can ensure that the first portion F11 is close to the boundary line L2 of the first first isolation column 501, and the distance d6 between the first portion F11 and the first first isolation column 501 in the first direction X is greater than or equal to 6μm, that is, d6≥6μm, which can effectively prevent the light shielding layer 403 of the first isolation area F1 from falling off.
[0126] For example, Figure 12 As shown, the dimension d15 of the second portion F31 in the first direction X is 30 μm, 35 μm, 40 μm, 45 μm, 50 μm or 60 μm, etc., which is not limited here.
[0127] By setting the size d14 of the first portion F11 in the first direction X to be 3 μm to 7 μm and the size d15 of the second portion F31 in the first direction X to be 30 μm to 60 μm, the problem of the light shielding layer 403 falling off can be avoided while meeting the requirements of rainbow pattern detection.
[0128] In some embodiments, as Figure 10 As shown, the ratio of the dimension d11 of the shortest point of the connecting bridge Q1 in the second direction Y to the sum of the shortest dimensions of the connecting bridge Q1 and the second light-transmitting hole K2 adjacent to the connecting bridge Q1 in the second direction (the sum of the dimensions is expressed as d12) ranges from 40% to 62%.
[0129] That is to say, the ratio of the dimension d11 of the shortest point of the connecting bridge Q1 in the second direction Y to the sum of the dimension d11 of the shortest point of the connecting bridge Q1 in the second direction Y and the dimension d12 of the shortest point of the second light-transmitting hole K2 adjacent to the connecting bridge Q1 in the second direction Y is in the range of 40% to 62%, that is, 62% ≥ d11 / (d11+d12) ≥ 40%.
[0130] For example, Figure 10 As shown, the ratio of the dimension d11 of the connecting bridge Q1 at the shortest point in the second direction Y to the sum of the dimensions d12 of the connecting bridge Q1 and the second light-transmitting hole K2 adjacent to the connecting bridge Q1 at the shortest point in the second direction Y, that is, the ratio d11 / (d11+d12) is 40%, 45%, 50%, 55% or 60%, etc., which is not limited here.
[0131] It should be noted that, for example, Figure 10As shown, since the light-shielding layer bridge region M4 is a circular ring structure, the second light-transmitting hole K2 can be configured as a fan-shaped hole. The size of the second light-transmitting hole K2 on the side close to the opening region H in the second direction Y is smaller than the size of the second light-transmitting hole K2 on the side away from the opening region H in the second direction Y. The size of the second light-transmitting hole K2 on the side close to the opening region H in the second direction Y is the size of its shortest point in the second direction Y. The sizes of the connecting bridges Q1 in the second direction Y can be equal.
[0132] For example, the connecting bridge Q1 may be configured to be fan-shaped or in other shapes, which is not limited here.
[0133] By setting the ratio of the dimension d11 of the shortest point of the connecting bridge Q1 in the second direction Y to the sum of the dimensions d12 of the shortest points of the connecting bridge Q1 and the second light-transmitting hole K2 adjacent to the connecting bridge Q1 in the second direction Y in the range of 40% to 62%, it can be ensured that the design of the light-shielding layer 403 in the hole edge area F meets the requirements of rainbow pattern detection, and can effectively prevent the light-shielding layer 403 from falling off.
[0134] In some embodiments, as Figure 10 As shown, the shortest dimension d11 of the connecting bridge Q1 in the second direction Y is greater than or equal to 30 μm, that is, d11 ≥ 30 μm, and the shortest dimension d12 of the second light-transmitting hole K2 in the second direction Y is less than or equal to 20 μm, that is, d12 ≤ 20 μm.
[0135] For example, when the ratio of the dimension d11 of the shortest portion of the connecting bridge Q1 in the second direction Y to the sum of the dimensions d12 of the connecting bridge Q1 and the second light-transmitting hole K2 adjacent to the connecting bridge Q1 at the shortest portions in the second direction is in the range of 40% to 62%, the dimension d11 of the shortest portion of the connecting bridge Q1 in the second direction Y is 30 μm, 35 μm, or 40 μm, etc., without limitation. The dimension d12 of the shortest portion of the second light-transmitting hole K2 in the second direction Y is 20 μm, 15 μm, or 10 μm, etc., without limitation.
[0136] In some embodiments, as Figure 11 and Figure 12 As shown, the dimension d13 of the light shielding layer bridge region M4 in the first direction X is greater than or equal to 60 μm, that is, d13 ≥ 60 μm.
[0137] Exemplarily, the dimension d13 of the light shielding layer bridge region M4 in the first direction X is 60 μm, 70 μm, or 80 μm, etc., which is not limited here.
[0138] For example, Figure 12As shown, the second light-transmitting hole K2 and the first light-shielding layer removal area Fa provided in the light-shielding layer 403 in the light-shielding layer bridge region M4 are both areas for rainbow detection. The requirement is met that the ratio of the orthographic projection area of the light-shielding layer 403 on the substrate 1 to the first isolation region F1, the encapsulation region F2, and the second isolation region F3 is in the range of 30% to 62%.
[0139] In some embodiments, as Figure 3 、 Figure 6 and Figure 12 As shown, the encapsulation region F2 is provided with an encapsulation dam 60, which surrounds the opening region H. The first isolation region F1 includes: a plurality of first isolation pillars 50 spaced apart in the first direction X, each of the plurality of first isolation pillars 50 surrounding the opening region H. The second isolation region F3 includes: a plurality of second isolation pillars 70 spaced apart in the first direction X, each of the plurality of second isolation pillars 70 surrounding the opening region H.
[0140] For example, Figure 3 、 Figure 6 and Figure 12 As shown, the encapsulation dam 60 and the second isolation pillars 70 are both annular structures surrounding the opening area H. The diameters of the plurality of second isolation pillars 70 increase sequentially along the first direction X. The provision of the encapsulation dam 60, the first isolation pillars 50, and the second isolation pillars 70 can improve the encapsulation capability of the opening edge area F and help isolate it from water vapor erosion.
[0141] In some embodiments, as Figure 3 、 Figure 6 and Figure 12 As shown, the display panel 100 further includes: at least one of a first source / drain metal layer 207 and a second source / drain metal layer 209, a first planarization layer 208, a second planarization layer 210, and a first support layer 305, disposed between the substrate 1 and the light shielding layer 403. The first source / drain metal layer 207 and at least one of the second source / drain metal layer 209, the first planarization layer 208, the second planarization layer 210, and the first support layer 305 are stacked in sequence along a third direction Z. The third direction Z is a direction from the substrate 1 to the light shielding layer 403. The first isolation pillar 50 and the second isolation pillar 70 are disposed in the same layer as at least one of the first source / drain metal layer 207 and the second source / drain metal layer 209. The encapsulation dam 60 includes a third portion 601 , a fourth portion 602 and a fifth portion 603 stacked in sequence along the third direction Z. The third portion 601 is disposed on the same layer as the first planarization layer 208 , the fourth portion 602 is disposed on the same layer as the second planarization layer 210 , and the fifth portion 603 is disposed on the same layer as the first support layer 305 .
[0142] Exemplarily, the materials of the first source / drain metal layer 207 and the second source / drain metal layer 209 include titanium / aluminum / titanium (Ti-Al-Ti). For example, the material of the first source / drain metal layer 207 is titanium / aluminum / titanium (Ti-Al-Ti) stacked along the third direction Z, and the material of the second source / drain metal layer 209 is titanium / aluminum / titanium (Ti-Al-Ti) stacked along the third direction Z. The materials of the first planarization layer 208, the second planarization layer 210, and the first supporting layer 305 include polyesterimide.
[0143] In some embodiments, as Figure 3 、 Figure 6 and Figure 12 As shown, the display panel 100 further includes: a first inorganic encapsulation film layer 306, an organic encapsulation film layer 401, a second inorganic encapsulation film layer 402, and a third planarization layer 404, which are disposed on a side of the first support layer 305 away from the substrate 1. The first inorganic encapsulation film layer 306, the organic encapsulation film layer 401, the second inorganic encapsulation film layer 402, the light shielding layer 403, and the third planarization layer 404 are stacked in sequence along a third direction Z. The third planarization layer 404 covers the first isolation region F1, the encapsulation region F2, and the second isolation region F3. In the second isolation region F3, the first inorganic encapsulation film layer 306, the organic encapsulation film layer 401, and the second inorganic encapsulation film layer 402 are sequentially disposed between the second isolation pillar 70 and the light shielding layer 403.
[0144] Exemplarily, the first inorganic encapsulation film layer 306 and the second inorganic encapsulation film layer 402 are formed by a chemical vapor deposition (CVD) process, and are used to encapsulate the hole edge region F, thereby isolating the hole edge region F from water vapor.
[0145] By arranging different film layer structures in the first isolation region F1 , the packaging region F2 and the second isolation region F3 , a better packaging effect is achieved in the hole edge region F.
[0146] In some embodiments, as Figure 3 、 Figure 6 and Figure 12 As shown, the display panel 100 further includes: a first gate conductive layer 203 and a second gate conductive layer 205 disposed between the substrate 1 and the first source / drain metal layer 207. The first gate conductive layer 203 and the second gate conductive layer 205 are stacked along a third direction Z. A first supporting portion 23A and a second supporting portion 25B are disposed on a side of the first spacer 50 and the second spacer 70 that is close to the substrate 1. The first supporting portion 23A is disposed on the same layer as the first gate conductive layer 203, and the second supporting portion 25B is disposed on the same layer as the second gate conductive layer 205.
[0147] For example, Figure 3 、 Figure 6 and Figure 12As shown, the first support portion 23A and the second support portion 25B are both annular structures surrounding the opening area H. The orthographic projections of the first isolation column 50, the first support portion 23A, and the second support portion 25B on the substrate 1 have a common overlapping area. The orthographic projections of the second isolation column 70, the first support portion 23A, and the second support portion 25B on the substrate 1 have a common overlapping area.
[0148] The provision of the first supporting portion 23A and the second supporting portion 25B can elevate the first isolation column 50 and the second isolation column 70 , thereby improving the packaging effect of the first isolation column 50 and the second isolation column 70 on the hole edge region F.
[0149] In order to facilitate understanding of the film layer stacking structure of the display panel 100, as shown in FIG. Figure 13 , which illustrates a film layer stacking structure of the display panel 100. It should be understood that this example is merely an example of the film layer stacking structure of the display panel 100, and does not limit the film layer stacking structure of the display panel 100.
[0150] like Figure 13 As shown, the display panel 100 includes: a substrate 1 and a driving circuit layer 2, a light-emitting device layer 3, and an encapsulation layer 4 stacked in sequence on the substrate 1. The driving circuit layer 2 includes: a first semiconductor layer 201, a first gate insulating layer 202, a first gate conductive layer 203, a second gate insulating layer 204, a second gate conductive layer 205, an interlayer dielectric layer 206, a first source / drain metal layer 207, a first planarization layer 208, a second source / drain metal layer 209, and a second planarization layer 210, stacked in sequence. The light-emitting device layer 3 includes: an anode layer 301, a pixel defining layer 302, a light-emitting layer 303, and a cathode layer 304, stacked in sequence. The encapsulation layer 4 includes: a first supporting layer 305, a first inorganic encapsulation film layer 306, an organic encapsulation film layer 401, a second inorganic encapsulation film layer 402, a light-shielding layer 403, and a third planarization layer 404, stacked in sequence.
[0151] In some embodiments, as Figure 3 、 Figure 6 and Figure 12 As shown, the hole edge area F also includes: a wiring area F4 arranged on the side of the second isolation area F3 close to the display area AA, and the size d16 of the light shielding layer 403 along the first direction X of the first isolation area F1, the packaging area F2, the second isolation area F3 and the wiring area F4 is greater than or equal to 580μm.
[0152] It should be noted that the dimension d16 of the light shielding layer 403 along the first direction X is the distance between the boundary line L4 of the light shielding layer 403 close to the display area AA and the boundary line L5 of the light shielding layer 403 close to the opening area H along the first direction X.
[0153] For example, Figure 3 、 Figure 6 and Figure 12 As shown, the aperture edge region F includes: a first isolation region F1, an encapsulation region F2, a second isolation region F3, and a wiring region F4, which are sequentially connected along a first direction X.
