During the etching of the isolation material layer, the etching liquid or etching gas can be more uniformly distributed in the first and second display areas.

Consequently, the connection impedance between the isolation layer and the first electrode in the first and second display areas is similar, with minimal difference, thereby reducing the possibility of brightness inhomogeneity (Mura) or color inconsistency in the display panel.

However, this disclosure may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0092] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0093] In each embodiment, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in each embodiment according to the specific circumstances.

[0094] It should be understood that when an element or layer is referred to as "on," "adjacent to," or "connected to" other elements or layers, it may be directly on, adjacent to, or connected to other elements or layers, or there may be intervening elements or layers. Conversely, when an element is referred to as "directly on," "directly adjacent to," or "directly connected to" other elements or layers, there are no intervening elements or layers. It should be understood that although the terms first, second, third, etc., may be used to describe various elements, components, areas, layers, and / or portions, these elements, components, areas, layers, and / or portions should not be limited by these terms. These terms are only used to distinguish one element, component, area, layer, or portion from another element, component, area, layer, or portion. Therefore, without departing from the teachings of this embodiment, the first element, component, area, layer, or portion discussed below may be referred to as a second element, component, area, layer, or portion.

[0095] Spatial relation terms such as “below,” “under,” “below,” “below,” “above,” “above,” etc., are used herein to describe the relationship between one element or feature shown in the figure and other elements or features. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms also include different orientations of the device in use and operation. For example, if the device in the figure is flipped, an element or feature described as “below,” “below,” or “below” will be oriented “above” the other element or feature. Therefore, the exemplary terms “below” and “under” can include both above and below orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.

[0096] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that when the terms “comprise” and / or “comprising” are used in this specification, the presence of the stated feature, integer, step, operation, element, and / or part is established, but the presence or addition of one or more other features, integers, steps, operations, elements, parts, and / or groups is not excluded.

Variations in the illustrated shapes due to, for example, manufacturing techniques and / or tolerances are to be expected. Therefore, embodiments of this specification should not be limited to the specific shapes of the regions shown herein, but rather include shape deviations due to, for example, manufacturing techniques. The regions shown in the figures are substantially schematic, and their shapes do not represent the actual shapes of regions of the device, nor do they limit the scope of this embodiment.

[0098] In one embodiment, see Figure 1 and Figure 2 The display panel 100 may have a display area 110 and a non-display area 120, with the non-display area 120 surrounding the display area 110. The display area 110 may have a first display area 111 and a second display area 112. Exemplarily, the first display area 111 may be a normal display area 110, and the second display area 112 may be an ambient light aperture area. This embodiment does not impose specific limitations on the area, distribution, and shape of the first display area 111 and the second display area 112.

[0099] In one embodiment, see Figure 3 A method for manufacturing a display panel 100 is provided, applicable to the aforementioned display panel 100. The method for manufacturing the display panel 100 may include the following steps:

[0100] Step S100: Provide substrate 130.

[0101] Step S400: An isolation material layer is formed on one side of the substrate 130.

[0102] Step S500: Pattern the isolation material layer, forming a plurality of first openings 200 and second openings 210 in the isolation material layer within the first display area 111 and the second display area 112. The first opening 200 includes a light-emitting opening, and the second opening 210 includes a virtual light-transmitting opening 211 located in the first display area 111 and a light-transmitting opening 212 located in the second display area 112. The remaining isolation material layer forms an isolation layer 140.

[0103] Step S600: A light-emitting unit 150 is formed in the first opening 200 located in the first display area 111 and the second display area 112.

[0104] In step S100, please refer to Figure 4 The substrate 130 can be a packaging substrate 130. As an example, multiple film layers can be provided on the substrate 130. For example, a first planarization layer 131 and a second planarization layer 132 can be provided on the substrate 130. Multiple wiring layers can be provided within the first planarization layer 131 and the second planarization layer 132.

[0105] In one possible example, after step S100, the following may be included:

[0106] Step S200: A photosensitive device is formed on the substrate 130 within the second display area 112.

[0107] A photosensitive device is used to receive light. As an example, the photosensitive device can adjust the brightness of the display panel 100 according to the light intensity. For example, the photosensitive device may include a photosensor, etc. Of course, the photosensitive device can be electrically connected to the wiring layer. The display panel 100 may include multiple photosensitive devices, which can be evenly distributed within the second display area 112. This embodiment does not specifically limit the number or distribution of the photosensitive devices.

[0108] In step S400, an isolation material layer can be formed on the entire surface of the substrate 130. At this time, the isolation material layer can be formed not only in the display area 110, but also in the non-display area 120.

[0109] In one possible example, the isolation material layer may comprise a multilayer conductive film. For instance, the isolation material layer may comprise a titanium layer and an aluminum layer, etc.

[0110] In step S500, please refer to Figure 5 After patterning the isolation material layer, the remaining isolation material layer forms the isolation layer 140. The first opening 200 of the isolation layer 140 includes multiple light-emitting openings. These multiple light-emitting openings can be evenly distributed in the first display area 111 and the second display area 112. Each light-emitting unit 150 has a corresponding light-emitting opening, and the light emitted by the light-emitting unit 150 can exit through the first opening 200. The second opening 210 includes multiple virtual light-transmitting openings 211 and multiple light-transmitting openings 212. The virtual light-transmitting openings 211 are located in the first display area 111. The virtual light-transmitting openings 211 may not have a light-transmitting function. The light-transmitting openings 212 are located in the second display area 112 and can be used to expose photosensitive devices, etc.

[0111] The composition and preparation of the isolation layer 140 mentioned in this application are further described in patents CN118251982A, 202410864269.8, PCT / CN2024 / 098407, PCT / CN2024 / 102783, PCT / CN2024 / 098217, PCT / CN2024 / 100935, PCT / CN2024 / 102785, PCT / CN2024 / 099419, PCT / CN2024 / 099072, and CN116685174A, for reference.

[0112] This embodiment does not impose specific limitations on the distribution, area, and shape of the first opening 200 and the second opening 210. In a first possible example, the second openings 210 have the same arrangement within the first display area 111 and the second display area 112. In a second possible example, multiple second openings 210 are arranged around the periphery of the first opening 200. Further, at least one second opening 210 is provided between adjacent first openings 200. In a third possible example, the orthographic projection of the virtual light-transmitting opening 211 onto the substrate 130 has the same area as the orthographic projection of the light-transmitting opening 212 onto the substrate 130. In a fourth possible example, the orthographic projection of the virtual light-transmitting opening 211 onto the substrate 130 has the same shape as the orthographic projection of the light-transmitting opening 212 onto the substrate 130. In a fifth possible example, the opening density of the first display area 111 is the same as the opening density of the second display area 112. In a sixth possible example, the orthographic projection area of ​​the second opening 210 onto the substrate 130 is smaller than the orthographic projection area of ​​the first opening 200 onto the substrate 130.

[0113] As an example, a patterned mask layer can be formed first on the isolation material layer, and then the isolation material layer can be etched using dry etching or wet etching based on the patterned mask layer, with the remaining isolation material layer forming the isolation layer 140. For example, dry etching can include at least one of reactive ion etching, inductively coupled plasma etching, or high-concentration plasma etching. It is understood that the light-emitting opening (first opening 200), the virtual light-transmitting opening 211, and the light-transmitting opening 212 can be formed simultaneously.

[0114] In step S600, please refer to Figure 6 A light-emitting unit 150 is formed within each of the first openings 200. As an example, the light-emitting unit 150 may include a red light unit 151, a green light unit 153, and a blue light unit 152. The red light unit 151, green light unit 153, and blue light unit 152 may be formed within the plurality of first openings 200 in a predetermined order. Of course, the light-emitting unit 150 may also include a white light unit, etc.

[0115] For further details, please refer to Figure 7 Furthermore, after forming the light-emitting unit 150, a first electrode 160 may be formed within each first opening 200. The first electrode 160 may include a cathode. Exemplarily, the first electrode 160 may be formed by a method such as vapor deposition.

[0116] For related technologies, please refer to Figure 8 , Figure 8In the related technology shown, the first display area 111 does not have a virtual light-transmitting opening 211. In this case, the opening density of the first display area 111 is less than that of the second display area 112, which leads to different etching load effects between the first display area 111 and the second display area 112. As an example, please refer to... Figure 9 Along a direction perpendicular to the substrate 130, the insulating layer 140 may include a top 141 and a support 142 sequentially disposed therein. The orthographic projection of the support 142 onto the substrate 130 lies within the orthographic projection of the top 141 onto the substrate 130. The edge of the orthographic projection of the top 141 onto the substrate 130 and the edge of the orthographic projection of the support 142 onto the substrate 130 have a difference ( ). Figure 12 (Mid-distance W). In related technologies, when etching the isolation material layer, the etching liquid is uniformly distributed on the isolation material layer. At this time, the amount of isolation material layer removed in different areas is different, resulting in different distances W between the isolation layers 140 in different areas. Therefore, when the first electrode (cathode) is formed by vapor deposition, the vapor deposition of the first electrode shows differences in overlap with the isolation material layer in different areas, which will cause uneven brightness (Mura) or inconsistent colors in the display panel.

[0117] In this embodiment, by adding a virtual light-transmitting opening 211 to the first display area 111, the opening density of the first display area 111 is increased, thereby narrowing the gap between the opening density of the first display area 111 and the opening density of the second display area 112. During the etching of the isolation material layer, the etching liquid or etching gas can be more uniformly distributed in the first display area 111 and the second display area 112. Furthermore, the etching liquid or etching gas can also be more uniformly distributed within each opening, which can reduce the etching load effect, making the volume of the isolation material layer removed within the first opening 200 of the first display area 111 and the second display area 112 similar, that is, the morphology (depth or width, or distance W) of the first opening 200 of the first display area 111 and the second display area 112 is similar. Furthermore, when light-emitting units 150 and first electrodes 160 are formed in each first opening 200, the light-emitting units 150 and first electrodes 160 in different first openings 200 have similar structures and small differences, thereby reducing the possibility of uneven brightness or inconsistent colors appearing in the display panel 100.

[0118] As an example, the similar morphologies of the first opening 200 of the first display area 111 and the second display area 112 provided in this embodiment may include: on the side of the first display area 111 near the first opening 200, the top 141 of the isolation layer 140 has a first edge line projected onto the substrate 130 (e.g., Figure 9 (AA'), the orthographic projection of the support portion 142 onto the substrate 130 has a second edge line (e.g., Figure 9(BB'), the first edge line and the second edge line have a first distance D1, and on the side of the second display area 112 near the first opening 200, the orthographic projection of the top 141 on the substrate 130 has a third edge line (e.g., BB'). Figure 9 (CC'), the orthographic projection of the support portion 142 onto the substrate 130 has a fourth edge line (e.g., CC'), Figure 9 (DD'), the third edge line and the fourth edge line have a second distance D2, and the first distance D1 and the second distance D2 are equal.

[0119] In one embodiment, see Figure 10 and Figure 11 Before step S400, the following are included:

[0120] Step S300: A pixel circuit layer 170 is formed on the substrate 130.

[0121] Accordingly, after step S500, the method for preparing the display panel 100 may further include:

[0122] Step S600: Form a shielding structure 180 corresponding to the virtual light-transmitting opening 211.

[0123] Step S700: A touch layer 171 is formed on the side of the isolation layer 140 facing away from the substrate 130.

[0124] In step S300, the pixel circuit layer 170 can be electrically connected to the photosensitive device, the light-emitting unit 150, etc. As an example, the pixel circuit layer 170 may include multiple wiring layers. The pixel circuit layer 170 can extend from the display area 110 to the non-display area 120. The non-display area 120 may also be provided with a circuit board or chip, which is electrically connected to the pixel circuit layer 170, thereby driving the photosensitive device and the light-emitting unit 150.

[0125] After forming the pixel circuit layer 170, a pixel definition layer 190 and a plurality of second electrodes 161 can be formed. The second electrodes 161 can be anodes. The second electrodes 161 are disposed corresponding to the first opening 200, meaning that there are no second electrodes 161 below the virtual light-transmitting openings 211 and 212 in the thickness direction of the display panel 100. The pixel definition layer 190 has pixel openings that expose the second electrodes 161. The orthographic projection of the pixel opening onto the substrate 130 can at least partially overlap with the orthographic projection of the first opening 200 onto the substrate 130, so that the pixel opening communicates with the first opening 200, thereby allowing the light-emitting unit 150 to contact the second electrodes 161 exposed by the pixel definition layer 190.

[0126] In step S600, the shielding structure 180 can be used to shield signal interference or signal crosstalk. As an example, the material of the shielding structure 180 may include a metallic material. The shielding structure 180 can be formed across the entire surface at the position corresponding to the virtual light-transmitting opening 211, and the shielding structure 180 can also be patterned to resemble a mesh, etc.

[0127] The shielding structure 180 is correspondingly disposed with respect to the virtual light-transmitting opening 211. In one possible example, the shielding structure 180 may cover the virtual light-transmitting opening 211 near the bottom of the pixel circuit layer 170. In another possible example, the shielding structure 180 may also cover the virtual light-transmitting opening 211 near the upper surface of the touch layer 171. In yet another possible example, the shielding structure 180 may fill the virtual light-transmitting opening 211, in which case the top surface of the shielding structure 180 may be flush with the top surface of the isolation layer 140. In the above three possible examples, the shielding structure 180 may be electrically connected to the isolation layer 140 surrounding the virtual light-transmitting opening 211. Of course, the shielding structure 180 may also be spaced apart from the isolation layer 140 surrounding the virtual light-transmitting opening 211.

[0128] The shielding structure 180 may include a single-layer structure. For example, the shielding structure 180 may include a single metal layer. The shielding structure 180 may also include a multi-layer structure. In this case, for example, one metal layer may cover the virtual light-transmitting opening 211 near the bottom of the pixel circuit layer 170, and another metal layer may cover the virtual light-transmitting opening 211 near the upper surface of the touch layer 171.

[0129] This embodiment does not limit the material of the shielding structure 180. For example, the material of the shielding structure 180 may include conductive materials such as titanium and aluminum.

[0130] In step S700, the touch layer 171 can be used to implement touch functionality. As an example, the touch layer 171 may include touch electrodes.

[0131] Please see Figure 7 The touch layer 171 may emit high-frequency signals, which may be transmitted from the virtual light-transmitting opening 211 to the pixel circuit layer 170. This high-frequency signal affects the pixel circuit layer 170 and thus the sensing accuracy of the touch layer 171, potentially impacting the display effect of the display panel 100. Therefore, please refer to... Figure 10 and Figure 11 In this embodiment, by setting a shielding structure 180 corresponding to the virtual light-transmitting opening 211, the shielding structure 180 shields the high-frequency signals emitted by the touch layer 171, thereby reducing the impact of the touch layer 171 on the pixel circuit layer 170.

[0132] For example, please refer to Figure 10The shielding structure 180 can be formed simultaneously with the formation of the first electrode 160. In this case, step S600 includes:

[0133] Step S620: A conductive material layer is formed on the side of the isolation layer 140 opposite to the substrate 130.

[0134] Step S621: Pattern the conductive material layer. The conductive material layer located in the first opening 200 and the virtual light-transmitting opening 211 forms a conductive layer, and the conductive layer located in the first opening 200 forms a first electrode 160, and the conductive layer located in the virtual light-transmitting opening 211 forms a shielding electrode.

[0135] In steps S620 to S621, the conductive material layer can be deposited over the entire surface of the isolation layer 140 on the side facing away from the substrate 130. At this time, the conductive material layer can be located at each opening and on the upper surface of the isolation layer 140 facing away from the substrate 130.

[0136] After patterning the conductive material layer, the conductive material layer inside the non-target first opening and the conductive material layer above the isolation layer 140 are removed, leaving a conductive layer. At this point, the conductive layer inside the target first opening 200 forms the first electrode 160, and the conductive layer inside the virtual light-transmitting opening 211 forms the shielding electrode. The first electrode 160 overlaps with the isolation layer 140, and the shielding electrode can also be connected to the isolation layer 140. It can be understood that the overlap between the shielding electrode and the isolation layer 140 can achieve electrical connection of multiple first electrodes 160.

[0137] In this example, firstly, by forming the first electrode 160 and the shielding electrode simultaneously in one process, the manufacturing process steps of the display panel 100 are saved. Secondly, the shielding structure 180 can overlap with the isolation layer 140 surrounding the virtual light-transmitting opening 211, thereby realizing the electrical connection of multiple first electrodes 160, and thus enabling the shielding structure 180 to have a stable potential, shielding the crosstalk between the touch layer 171 and the pixel circuit layer 170.

[0138] In addition, in other cases, please refer to Figure 11 When forming the virtual light-transmitting opening 211, the insulating material layer at the bottom of the virtual light-transmitting opening 211 can be retained, and the insulating material layer at the bottom of the virtual light-transmitting opening 211 can be used as a shielding structure 180. In this case, step S500 includes:

[0139] Step S510: Etch the isolation material layer to form a first opening 200, a light-transmitting opening 212, and a virtual light-transmitting opening 211. The first opening 200 and the light-transmitting opening 212 have a first depth, and the virtual light-transmitting opening 211 has a second depth, which is less than the first depth. The isolation layer 140 located at the bottom of the virtual light-transmitting opening 211 serves as a shielding structure 180.

[0140] If the material of the insulating material layer has a shielding function, the insulating material layer at the bottom of the virtual light-transmitting opening 211 can be retained. In this case, the insulating material layer at the bottom of the virtual light-transmitting opening 211 can be used as a shielding structure 180. Furthermore, if the material of the insulating material layer has a conductive function, the insulating material layer at the bottom of the virtual light-transmitting opening 211 can be used as a shielding electrode.

[0141] Furthermore, step S400 may include: sequentially forming a second isolation material layer and a first isolation material layer on one side of the substrate 130.

[0142] Accordingly, step S500 may include: sequentially etching the first isolation material layer and the second isolation material layer to form the first isolation sub-part 1421 and the second isolation sub-part 1422 of the support portion 142, and the second isolation material layer retained at the bottom of the virtual light-transmitting opening 211 includes a shielding structure 180. As an example, the orthographic projection of the second isolation sub-part 1422 onto the substrate 130 can cover the orthographic projection of the first isolation sub-part 1421 onto the substrate 130.

[0143] Of course, during the etching of the isolation material layer, the isolation material layer at the bottom of the first opening 200 and the light-transmitting opening 212 is completely etched away. At this time, the first opening 200 and the light-transmitting opening 212 expose the film layer below the isolation material layer (for example, the layer below the isolation material layer can be the pixel definition layer 190). This embodiment does not limit the difference between the first depth and the second depth. Exemplarily, the difference between the first depth and the second depth can range from 1 mm to 5 mm. The above data is only an example, and in actual embodiments, the difference between the first depth and the second depth is not limited to the above data.

[0144] In this embodiment, the insulating material layer at the bottom of the virtual light-transmitting opening 211 is retained, and the insulating material layer at the bottom of the virtual light-transmitting opening 211 serves as the shielding structure 180. This eliminates the need for a separate step to form the shielding structure 180, saving on the manufacturing process steps of the display panel 100. Furthermore, the shielding structure 180 in this embodiment can also realize the function of electrically connecting multiple first electrodes 160.

[0145] In one example, see Figure 10 Step S600 includes:

[0146] Step S610: A light-emitting material layer is formed on the side of the isolation layer 140 away from the substrate 130, and the light-emitting material layer located in the virtual light-transmitting opening 211 forms a virtual light-emitting unit 151.

[0147] It is understood that a light-emitting material layer is also formed within the first opening 200, and this light-emitting material layer can form a light-emitting unit 150. However, the virtual light-emitting unit 151 may not emit light, while the light-emitting unit 150 may emit light normally. In this case, the virtual light-emitting unit 151 may only be used to cover the bottom of the virtual light-transmitting opening 211.

[0148] Simultaneously with step S610, a light-emitting material layer is also formed within the light-transmitting opening 212, forming a sacrificial unit. Correspondingly, in step S620, the conductive material layer within the light-transmitting opening 212 can form a sacrificial electrode. It can be understood that after step S600, the sacrificial unit and sacrificial electrode within the light-transmitting opening 212 need to be removed to improve the light transmittance of the light-transmitting opening 212. Further, in step S610, multiple layers of sacrificial units can be formed within the light-transmitting opening 212. In step S620, multiple layers of sacrificial electrodes can be formed within the light-transmitting opening 212. The multiple layers of sacrificial units and multiple layers of sacrificial electrodes can be removed in a single etching process or in stages.

[0149] In this embodiment, a luminescent material layer is also formed within the virtual light-transmitting opening 211, thereby rapidly forming the virtual light-emitting unit 151 and saving fabrication process steps. Furthermore, in this embodiment, the sacrificial unit and sacrificial electrode located within the light-transmitting opening 212 are removed, thereby increasing the light transmittance of the light-transmitting opening 212.

[0150] The following exemplifies the fabrication process of the virtual light-emitting unit 151, the sacrificial unit, and the sacrificial electrode. It should be noted that the following process is for illustrative purposes only, and specific embodiments are not necessarily based on the following process. The virtual light-emitting unit 151, the sacrificial unit, and the sacrificial electrode provided in this application are also not limited to the following process.

[0151] The first opening 200 may include a first sub-opening, a second sub-opening, and a third sub-opening for setting different light-emitting units 150. The light-emitting unit 150 includes a first light-emitting unit, a second light-emitting unit, and a third light-emitting unit with different light-emitting colors. For example, the first light-emitting unit, the second light-emitting unit, and the third light-emitting unit may be a red light unit 151, a green light unit 153, and a blue light unit 152, respectively.

[0152] As an example, step S610 may include:

[0153] Step S611: While forming the first light-emitting unit in the first sub-opening, a first virtual light-emitting unit is formed in the virtual light-transmitting opening 211, and a first sacrificial unit is formed in the light-transmitting opening 212.

[0154] Step S612: While forming a second light-emitting unit in the second sub-opening, a second virtual light-emitting unit is formed in the virtual light-transmitting opening 211, and a second sacrificial unit is formed in the light-transmitting opening 212.

[0155] Step S613: Form a third light-emitting unit only in the third sub-opening, remove the second virtual light-emitting unit in the virtual light-transmitting opening 211, and remove the first sacrificial unit and the second sacrificial unit in the light-transmitting opening 212.

[0156] In step S611, for example, first light-emitting units can be formed within the first sub-opening, the second sub-opening, the third sub-opening, the virtual light-transmitting opening 211, and the light-transmitting opening 212. Then, the first light-emitting units located within the second and third sub-openings can be removed, while the first light-emitting units located within the first sub-opening, the virtual light-transmitting opening 211, and the light-transmitting opening 212 are retained. Furthermore, the first light-emitting unit located within the virtual light-transmitting opening 211 forms a first virtual light-emitting unit, and the first light-emitting unit located within the light-transmitting opening 212 forms a first sacrificial unit.

[0157] In step S612, for example, a second light-emitting unit may be formed on the side of the first light-emitting unit facing away from the substrate 130, the second sub-opening, the third sub-opening, the side of the first virtual light-emitting unit facing away from the substrate 130, and the side of the first sacrificial unit facing away from the substrate 130. Then, the second light-emitting units located on the side of the first light-emitting unit facing away from the substrate 130 and in the third sub-opening may be removed. Furthermore, the second light-emitting unit located in the virtual light-transmitting opening 211 forms a second virtual light-emitting unit, and the second light-emitting unit located in the light-transmitting opening 212 forms a second sacrificial unit.

[0158] In step S613, a third light-emitting unit can be formed within the third sub-opening using a mask or the like. At this point, the first, second, and third light-emitting units are complete. Afterward, the second virtual light-emitting unit within the virtual light-transmitting opening 211 can be removed, while the first virtual light-emitting unit remains. The first and second sacrificial units within the light-transmitting opening 212 can also be removed to ensure the transmittance of the light-transmitting opening 212. As an example, the second virtual light-emitting unit within the virtual light-transmitting opening 211 can be removed simultaneously with the second sacrificial unit within the light-transmitting opening 212. Then, the first sacrificial unit is removed separately.

[0159] In this embodiment, by simultaneously fabricating a virtual light-emitting unit and a sacrificial light-emitting unit during the fabrication of the light-emitting unit 150, the isolation layer 140 can be protected. This prevents the light-transmitting opening 212 and the isolation layer 140 at the virtual light-transmitting opening from being affected by the etching process, thus avoiding the need for a separate step of fabricating the virtual light-emitting unit. Furthermore, the virtual light-emitting unit 151 does not have a light-emitting function and will not affect the display effect of the display panel 100.

[0160] Furthermore, while removing the second virtual light-emitting unit within the virtual light-transmitting opening 211, the second sacrificial unit within the light-transmitting opening 212 can also be removed to further accelerate the manufacturing efficiency of the display panel 100.

[0161] Furthermore, after removing the second sacrificial unit within the light-transmitting opening 212, the first sacrificial unit within the light-transmitting opening 212 also needs to be removed, while retaining the first virtual light-emitting unit within the virtual light-transmitting opening 211 and the shielding electrode located on the side of the first virtual light-emitting unit away from the substrate to form a shielding structure.

[0162] Furthermore, in the exemplary process described above, an encapsulation unit 191 is formed on each light-emitting unit 150. The encapsulation unit 191 can be formed using methods such as chemical vapor deposition. Moreover, the encapsulation unit 191 can cover the virtual light-emitting unit 151. As an example, the encapsulation unit 191 located on the encapsulation unit 191 can form a shielding encapsulation unit. The orthographic projection of the shielding encapsulation unit onto the substrate 130 can cover the orthographic projection of the virtual light-emitting unit 151 onto the substrate 130. As an example, the pixel definition layer does not have pixel openings within the virtual light-transmitting opening 211, which results in the top surface of the shielding encapsulation unit being higher than the top surface of the encapsulation unit in the thickness direction of the display panel 100.

[0163] Of course, a protective layer 192 can then be formed over the entire surface to protect the underlying structures. The protective layer 192 can be made flat using methods such as chemical mechanical polishing or mechanical polishing. In this embodiment, whether excessive polishing has occurred can be determined by whether the top surface of the higher shielding encapsulation unit is exposed.

[0164] It should be understood that, although Figure 3 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 3At least some of the steps in the process may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but may be executed at different times. The execution order of these steps or stages is not necessarily sequential, but may be executed in turn or alternately with other steps or at least some of the steps or stages in other steps.

[0165] Based on the same inventive concept, please refer to Figure 1 and Figure 10 This embodiment also provides a display panel 100, which can be manufactured using the manufacturing method of the display panel 100 provided in any one or a combination of the above embodiments.

[0166] The display panel 100 may have a display area 110 and a non-display area 120, with the non-display area 120 surrounding the display area 110. The display area 110 may have a first display area 111 and a second display area 112. For example, the first display area 111 may be a normal display area 110, and the second display area 112 may be an ambient light aperture area. The light transmittance of the first display area 111 may be less than the light transmittance of the second display area 112. This embodiment does not specifically limit the light transmittance of the first display area 111 and the light transmittance of the second display area 112.

[0167] The display panel 100 includes a substrate 130, an insulating layer 140, and a light-emitting unit 150.

[0168] The substrate 130 can be a packaging substrate 130. As an example, the substrate 130 may have multiple film layers. For example, the substrate 130 may have multiple wiring layers.

[0169] Please see Figure 5 An isolation layer 140 is located on one side of the substrate 130. The isolation layer 140 has a first opening 200 and a second opening 210 in both the first display area 111 and the second display area 112. The first opening 200 includes a light-emitting opening. Multiple light-emitting openings can be evenly distributed in the first display area 111 and the second display area 112. Each light-emitting unit 150 has a corresponding light-emitting opening, and the light emitted by the light-emitting unit 150 can be emitted from the light-emitting opening. The second opening 210 includes a virtual light-transmitting opening 211 and a light-transmitting opening 212. The virtual light-transmitting opening 211 is located in the first display area 111, and the light-transmitting opening 212 is located in the second display area 112. The virtual light-transmitting opening 211 may not have a light-transmitting function. The light-transmitting opening 212 is located in the second display area 112 and can be used to expose a photosensitive device, which can receive ambient light incident from the light-transmitting opening 212. As an example, the photosensitive device can adjust the brightness of the display panel 100 according to the light intensity. For example, photosensitive devices can include photosensors, etc.

[0170] This embodiment does not impose specific limitations on the distribution, area, and shape of the first opening 200 and the second opening 210. In a first possible example, the second openings 210 have the same arrangement within the first display area 111 and the second display area 112. In a second possible example, multiple second openings 210 are arranged around the periphery of the first opening 200. Further, at least one second opening 210 is provided between adjacent first openings 200. In a third possible example, the orthographic projection of the virtual light-transmitting opening 211 onto the substrate 130 has the same area as the orthographic projection of the light-transmitting opening 212 onto the substrate 130. In a fourth possible example, the orthographic projection of the virtual light-transmitting opening 211 onto the substrate 130 has the same shape as the orthographic projection of the light-transmitting opening 212 onto the substrate 130. In a fifth possible example, the opening density of the first display area 111 is the same as the opening density of the second display area 112. In a sixth possible example, the insulating layer 140 may have an interconnected top 141 and a support 142, with the support 142's orthographic projection onto the substrate 130 located within the orthographic projection of the top 141 onto the substrate 130. Further, on the side of the first display area 111 near the first opening 200, the orthographic projection of the top 141 of the insulating layer 140 onto the substrate 130 has a first edge line (e.g., Figure 9 (AA'), the orthographic projection of the support portion 142 onto the substrate 130 has a second edge line (e.g., Figure 9 (BB'), the first edge line and the second edge line have a first distance, and on the side of the second display area 112 near the first opening 200, the orthographic projection of the top 141 on the substrate 130 has a third edge line (e.g., BB'). Figure 9 (CC'), the orthographic projection of the support portion 142 onto the substrate 130 has a fourth edge line (e.g., CC'), Figure 9 (DD'), the third edge line and the fourth edge line have a second distance, and the first distance and the second distance are equal.

[0171] Please see Figure 6 Each first opening 200 contains a light-emitting unit 150. As an example, the light-emitting unit 150 may include a red light unit 151, a green light unit 153, and a blue light unit 152. The red light unit 151, green light unit 153, and blue light unit 152 may be formed in a preset order within multiple first openings 200. Of course, the light-emitting unit 150 may also include a white light unit, etc.

[0172] In this embodiment, by adding a virtual light-transmitting opening 211 to the first display area 111, the opening density of the first display area 111 is increased, narrowing the gap between the opening density of the first display area 111 and the opening density of the second display area 112. Consequently, during the etching of the isolation material layer, the etching liquid or etching gas can be more uniformly distributed in the first display area 111 and the second display area 112. Furthermore, the etching liquid or etching gas can be more uniformly distributed within each opening, which reduces the etching load effect, resulting in similar volumes of isolation material removed from the light-emitting openings in the first and second display areas 111 and 112. That is, the morphology (depth or width, etc.) of the light-emitting openings in the first and second display areas 111 and 112 are similar. Furthermore, when forming light-emitting units 150 and first electrodes 160 within each light-emitting opening, the structures of the light-emitting units 150 and first electrodes 160 within different light-emitting openings are similar with minimal differences, thereby reducing the possibility of uneven brightness (Mura) or inconsistent color in the display panel 100.

[0173] In one embodiment, the display panel 100 includes a touch layer 171, a pixel circuit layer 170, and a shielding structure 180. The touch layer 171 is located on the side of the isolation layer 140 away from the substrate 130, the pixel circuit layer 170 is located on the side of the isolation layer 140 close to the substrate 130, and the shielding structure 180 is located between the touch layer 171 and the pixel circuit layer 170, and is correspondingly disposed to the second opening 210. For example, the orthographic projection of the second opening 210 on the substrate 130 is within the orthographic projection range of the shielding structure 180 on the substrate 130.

[0174] The pixel circuit layer 170 can be electrically connected to the photosensitive device, the light-emitting unit 150, etc. As an example, the pixel circuit layer 170 may include multiple wiring layers. The pixel circuit layer 170 can extend from the display area 110 to the non-display area 120. The non-display area 120 may be provided with a circuit board or chip, which is electrically connected to the pixel circuit layer 170 to drive the photosensitive device and the light-emitting unit 150.

[0175] The touch layer 171 can be used to implement touch functionality. As an example, the touch layer 171 may include touch electrodes.

[0176] The shielding structure 180 can be used to shield signal interference or signal crosstalk. As an example, the material of the shielding structure 180 may include a metallic material. The shielding structure 180 can be formed on an entire surface at a position opposite to the virtual light-transmitting opening 211, in which case the orthographic projection of the shielding structure 180 on the substrate 130 covers the orthographic projection of the virtual light-transmitting opening 211 on the substrate 130. The shielding structure 180 can also be patterned to resemble a mesh or the like.

[0177] In one possible example, the shielding structure 180 may be located within the virtual light-transmitting opening 211; for example, the shielding structure 180 may cover the virtual light-transmitting opening 211 near the bottom of the pixel circuit layer 170. In another possible example, the shielding structure 180 may also cover the virtual light-transmitting opening 211 near the upper surface of the touch layer 171. In both of these possible examples, the shielding structure 180 may be electrically connected to the isolation layer 140 surrounding the virtual light-transmitting opening 211. In the first example, along a direction perpendicular to the substrate 130, the isolation layer 140 includes a top 141 and a support portion 142 arranged sequentially, and the shielding structure 180 connects to the adjacent top 141. In the second example, the shielding structure 180 may fill the virtual light-transmitting opening 211, in which case the top surface of the shielding structure 180 is flush with the top 141. Of course, the shielding structure 180 may also be spaced apart from the isolation layer 140 surrounding the virtual light-transmitting opening 211.

[0178] The touch layer 171 may emit high-frequency signals, which may be transmitted from the virtual light-transmitting opening 211 to the pixel circuit layer 170, affecting the pixel circuit layer 170 and potentially impacting the display effect of the display panel 100. Therefore, in this embodiment, a shielding structure 180 is provided opposite to the virtual light-transmitting opening 211. This shielding structure 180 blocks the high-frequency signals emitted by the touch layer 171, thereby reducing the impact of the touch layer 171 on the pixel circuit layer 170.

[0179] Of course, no shielding structure 180 is provided at the position opposite to the light-transmitting opening 212, thereby improving the light transmittance of the light-transmitting opening 212.

[0180] In one possible example, please see Figure 10 The first electrode 160 and the shielding structure 180 are disposed on the same layer. At this time, the display panel 100 includes a conductive layer, which includes the shielding structure 180 and the first electrode 160. The first electrode 160 is located within the first opening 200, and the orthogonal projection of the first electrode 160 on the substrate 130 covers the orthogonal projection of the light-emitting unit 150 on the substrate 130. The first electrode 160 is electrically connected to the isolation layer 140 surrounding the first opening 200.

[0181] The shielding structure 180 may include shielding electrodes. The first electrode 160 and the shielding structure 180 may be formed simultaneously, in which case at least a portion of the shielding electrode and the first electrode 160 are located in the same conductive layer. The first electrode 160 overlaps with the isolation layer 140, and the shielding structure 180 is also connected to the isolation layer 140. It is understood that the shielding structure 180 and the isolation layer 140 can achieve electrical connections between multiple first electrodes 160.

[0182] In another possible example, see Figure 11When forming the virtual light-transmitting opening 211, an insulating material layer at the bottom of the virtual light-transmitting opening 211 can be retained, serving as a shielding structure 180. As an example, the light-emitting opening and the light-transmitting opening 212 have a first depth, and the virtual light-transmitting opening 211 has a second depth, which is less than the first depth. This embodiment does not limit the difference between the first depth and the second depth. Exemplarily, the difference between the first depth and the second depth can range from 1 mm to 5 mm. The above data is only an example; in actual embodiments, the difference between the first depth and the second depth is not limited to the above data.

[0183] Furthermore, the support portion 142 of the isolation layer 140 includes a first isolation sub-portion 1421 and a second isolation sub-portion 1422. In one example, the orthographic projection of the second isolation sub-portion 1422 onto the substrate 130 can cover the orthographic projection of the first isolation sub-portion 1421 onto the substrate 130. In this case, when forming the first isolation sub-portion 1421 and the second isolation sub-portion 1422, the second isolation sub-portion 1422 retained at the bottom of the virtual light-transmitting opening 211 includes a shielding structure 180. In another example, the shielding structure 180 includes a third isolation sub-portion located within the virtual light-transmitting opening 211, and the third isolation sub-portion and the second isolation sub-portion 1422 are fabricated in the same layer. In addition, the display panel 100 also includes a first electrode 160 within the first opening 200 and covering the light-emitting unit 150, at least a portion of the first electrode 160 overlapping the sidewall of the first isolation sub-portion 1421 near the first opening. For example, the material of the first isolation sub-portion 1421 may include aluminum, etc., and the material of the second isolation sub-portion 1422 may include molybdenum, etc. By setting the first electrode 160 to overlap with the side wall of the first isolation sub-part 1421 near the first opening 200, the overlap resistance of the first electrode 160 in the first display area 111 is consistent with the overlap resistance in the second display area 111, so that the brightness of each light-emitting unit 150 is consistent and the display is uniform.

[0184] In one embodiment, the display panel 100 further includes a virtual light-emitting unit 151.

[0185] The virtual light-emitting unit 151 is located within the virtual light-transmitting opening 211. The orthographic projection of the virtual light-emitting unit 151 onto the substrate 130 lies within the orthographic projection range of the shielding electrode onto the substrate 130. The virtual light-emitting unit 151 may have the same color as any of the light-emitting units 150. For example, the light-emitting units 150 may include at least a first light-emitting unit, a second light-emitting unit, and a third light-emitting unit with different emission colors, and the emission color of the virtual light-emitting unit 151 may be the same as the color of any one of the first, second, or third light-emitting units.

[0186] In this embodiment, a virtual light-emitting unit 151 is provided within the virtual light-transmitting opening 211, thereby increasing the shielding effect. Moreover, the virtual light-emitting unit 151 can be fabricated in the same process as the light-emitting unit 150, eliminating the need for a removal step, thus improving the fabrication efficiency of the display panel 100.

[0187] In one embodiment, the display panel 100 further includes an encapsulation unit 191.

[0188] The packaging unit 191 may include a plurality of spaced-apart packaging units, each packaging unit being disposed on the side of the first electrode 160 facing away from the substrate 130. Each packaging unit includes a first packaging portion 1911 located within the first opening 200 and a second packaging portion 1912 located on the side of the isolation layer 140 facing away from the substrate 130. Adjacent second packaging portions 1912 are spaced apart on the side of the isolation layer 140 facing away from the substrate 130.

[0189] At this time, the shielding structure 180 also includes a shielding encapsulation unit 181, which is at least partially located within the virtual light-transmitting opening 211 and covers the shielding electrode. The orthogonal projection of the shielding electrode onto the substrate 130 is within the orthogonal projection range of the shielding encapsulation unit 181 onto the substrate 130. It is understood that the shielding encapsulation unit 181 may have the same shape, material, etc., as the encapsulation unit 191. Moreover, the shielding encapsulation unit 181 may be fabricated in the same process as the encapsulation unit 191. Furthermore, the height of the shielding encapsulation unit 181 may be greater than that of the encapsulation unit 191.

[0190] In one possible example, the shielding encapsulation unit includes a first shielding encapsulation portion 1811 located within the virtual light-transmitting opening 211 and a second shielding encapsulation portion 1812 located on the side of the isolation layer 140 facing away from the substrate 130. The second shielding encapsulation portion 1812 and the second encapsulation portion 1912 are spaced apart on the side of the isolation layer 140 facing away from the substrate 130.

[0191] In another possible example, two stacked shielding structures 180 are disposed within the virtual light-transmitting opening 211, with at least one shielding electrode of the shielding structure 180 in contact with the isolation layer 140 surrounding the virtual light-transmitting opening 211. The virtual light-emitting units 151 of the two shielding structures have different emission colors. This example does not impose specific limitations on the color of the virtual light-emitting unit 151.

[0192] In this embodiment, by setting up the encapsulation unit 191 and the shielding encapsulation unit 181, the protection of the light-emitting unit 150 and the virtual light-emitting unit 151 is improved.

[0193] Furthermore, the display panel 100 also includes a protective layer 192, which covers not only the encapsulation unit 191 and the shielding encapsulation unit 181, but also the remaining structures. If the protective layer 192 is an inorganic material, the encapsulation unit 191 and the shielding encapsulation unit 181 can be organic materials. Alternatively, if the protective layer 192 is an organic material, the encapsulation unit 191 and the shielding encapsulation unit 181 can be inorganic materials. The protective layer 192 may have a flat surface on the side facing away from the substrate 130, allowing structures such as polarizers to be formed on this flat surface.

[0194] In one embodiment, the display panel 100 further includes structures such as a second electrode layer and a pixel definition layer 190.

[0195] The second electrode layer is located on the side of the light-emitting unit 150 near the substrate 130. The second electrode layer may include a plurality of spaced-apart second electrodes 161. The second electrodes 161 may include anodes. The second electrodes 161 are correspondingly disposed with the first opening 200, and the first opening 200 exposes at least a portion of the second electrodes 161.

[0196] The pixel definition layer 190 is located on the side of the isolation layer 140 near the substrate 130. The pixel definition layer 190 has a pixel opening that exposes a portion of the second electrode 161. The pixel opening communicates with the first opening 200, and the orthographic projection of the second electrode 161 on the substrate 130 covers the orthographic projection of the pixel opening on the substrate 130, thereby facilitating the emission of light emitted by the light-emitting unit 150.
