[0052] This application provides a display panel, which may be an organic light-emitting diode (OLED) display panel, or other types of display panels, such as micro light-emitting diode (Micro-LED) or quantum light-emitting diode (QLED) display panels.

[0053] Please refer to the following: Figure 1 and Figure 2 The first aspect of this application provides a display panel 100, which includes a substrate 10, an isolation structure 40, a light-emitting unit layer 20, and a touch layer 50. The isolation structure 40 is disposed on one side of the substrate 10 and forms a light-transmitting opening 42 and a plurality of isolation openings 41. The light-emitting unit layer 20 is disposed on one side of the substrate 10 and includes a plurality of spaced light-emitting units 21. The orthographic projection of the light-emitting units 21 on the substrate 10 is located within the orthographic projection of the isolation openings 41 on the substrate 10. The touch layer 50 is disposed on the side of the light-emitting unit layer 20 away from the substrate 10 and includes touch electrodes 51. At least a portion of the outer periphery of the orthographic projection of the light-emitting units 21 on the substrate 10 is surrounded by the orthographic projection of the touch electrodes 51 on the substrate 10. The orthographic projection of the light-transmitting opening 42 on the substrate 10 is located between the orthographic projection of the light-emitting units 21 on the substrate 10 and the orthographic projection of the touch electrodes 51 on the substrate 10.

[0054] The substrate 10 includes a substrate 11 and a driving circuit layer 12 disposed on the substrate 11. The substrate 11 can be a rigid substrate 11 made of materials such as glass or plastic, or a flexible substrate 11 made of materials such as polyethersulfone (PES), polyacrylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyarylate, polyimide (PI), polycarbonate (PC), or cellulose acetate propionate (CAP). The driving circuit layer 12 contains a driving circuit for controlling the light emission of the light-emitting unit layer 20. The driving circuit layer 12 is generally composed of inorganic film layers such as a metal layer, a semiconductor layer (active layer), and an insulating layer 127. By patterning these inorganic film layers, a driving circuit for controlling the light emission of the light-emitting unit layer 20 can be formed. There are various ways to implement the specific circuit structure, which will not be described in detail here.

[0055] Because of the isolation structure 40, the precision mask can be eliminated when depositing the light-emitting layer 212. However, when fabricating light-emitting units 21 of different colors, it is necessary to first deposit light-emitting units 21 of a specific color across the entire surface of the display panel 100, and then etch the isolation openings 41 in the display panel 100 used to set other colored light-emitting units 21 to remove the light-emitting material and encapsulation material of the other colored light-emitting units 21. This process is then repeated for different colored light-emitting units 21 to form light-emitting units 21 of different colors.

[0056] It should be noted that in some embodiments, as shown in the figure, the orthographic projection of the isolation structure 40 onto the substrate 10 in the top view of the display panel 100 is annular. The presence of the isolation structure 40 allows the light-emitting layers 212 of different light-emitting units 21 to be separated during the fabrication of the display panel 100. Specifically, during the fabrication of the display panel 100, the isolation structure 40 is typically formed first, and then the light-emitting layers 212 are deposited directly without the aid of a precision mask. During this process, due to the presence of the isolation structure 40, some light-emitting material is deposited within the isolation opening 41, and some light-emitting material is deposited on the side of the isolation structure 40 facing away from the substrate 10. This results in the light-emitting material on different sides of the isolation structure 40 in the direction parallel to the plane of the substrate 10 being discontinuous, thus achieving the separation of the light-emitting layers 212 of each light-emitting unit 21 without the need for a precision mask. Since the evaporation of the light-emitting layer 212 does not require a precision mask, the cost is reduced. Furthermore, the shadowing effect of evaporating the light-emitting layer 212 with a precision mask is avoided, allowing for a reduction in the spacing between the light-emitting units 21, thereby improving the brightness of the display surface. Moreover, since the electron transport layer, electron injection layer, hole transport layer, and hole injection layer of the light-emitting layer 212 are all isolated by the isolation structure 40, crosstalk between the light-emitting units 21 can be prevented, improving the display effect of the display panel 100.

[0057] The light-emitting unit layer 20 may include multiple light-emitting units 21 arranged at intervals, and may include light-emitting units 21 of different colors. For example, it may include blue light-emitting units 21, red light-emitting units 21, and green light-emitting units 21 arranged at intervals. In addition, each pixel unit may also have four or more light-emitting units 21, in addition to the above three colors of light-emitting units 21, plus light-emitting units 21 of other colors such as white. Each light-emitting unit 21 includes a first electrode 211, a light-emitting layer 212, and a second electrode 213 stacked in sequence, with the first electrode 211 disposed on the substrate 10. The light-emitting layer 212 includes a light-emitting material layer, a hole transport layer, and an electron transport layer, etc. When the first electrode 211 and the second electrode 213 are energized, electrons and holes migrate from the electron transport layer and the hole transport layer to the light-emitting material layer, respectively, and meet in the light-emitting material layer to form excitons, which excite the light-emitting molecules, thereby generating visible light to achieve the purpose of display. One of the first electrode 211 and the second electrode 213 can serve as the anode of the light-emitting layer 212, and the other as the cathode of the light-emitting layer 212. In this embodiment, the first electrode 211 is used as the anode of the light-emitting layer 212 and the second electrode 213 is used as the cathode of the light-emitting layer 212 for illuminating purposes.

[0058] The light-transmitting opening 42 on the isolation structure 40 corresponds to the camera, fingerprint sensor, and other related components, providing a channel for light transmission for these functional components. Taking a camera as an example, when the display panel 100 is used in electronic devices (such as mobile phones), the camera needs to capture image information through the display panel 100. The presence of the light-transmitting opening 42 allows light to reach the camera and other sensors smoothly without being excessively blocked by other structures on the display panel 100, ensuring their normal operation. For fingerprint sensors, which may involve light emission and reflection, the light-transmitting opening 42 also provides a path for the propagation of relevant light, thereby enabling functions such as fingerprint recognition.

[0059] The primary function of the touch layer 50 is to detect touch operations. When a user touches the display panel 100, the touch layer 50 detects the touch location, pressure, and other information, and transmits this information to the relevant circuitry for processing, thereby enabling human-computer interaction, such as clicking, swiping, and zooming on a mobile phone. The touch layer 50 achieves its touch detection function through its internal touch electrodes 51 and other structures. The main function of the touch electrodes 51 is to sense touch signals. When a user touches the display panel 100, it causes changes in physical quantities such as the electric field around the touch electrodes 51. By detecting these changes, information such as the touch location can be determined.

[0060] At least a portion of the outer periphery of the orthographic projection of each light-emitting unit 21 onto the substrate 10 is surrounded by the orthographic projection of the touch electrode 51 onto the substrate 10. The orthographic projection of the light-transmitting opening 42 onto the substrate 10 is located between the orthographic projection of the light-emitting unit 21 onto the substrate 10 and the orthographic projection of the touch electrode 51 onto the substrate 10. That is, the originally larger light-transmitting opening 42 is divided into smaller light-transmitting openings 42, so that the touch electrode 51 can be arranged around the periphery of each light-emitting unit 21, and the arrangement of the light-transmitting opening 42 does not affect the arrangement of the touch electrode 51. In the display panel 100 of this application, this distribution of touch electrodes 51 around the light-emitting unit 21 ensures that each light-emitting unit 21 has a touch electrode 51 on its outer periphery. In this way, at a wide viewing angle, the degree of brightness reduction caused by the touch electrode 51 blocking the light of each light-emitting unit 21 is about the same, thereby reducing the degree of brightness attenuation of each light-emitting unit 21 at a wide viewing angle, reducing the color shift phenomenon of the display panel 100, and optimizing the display effect while realizing the touch detection function. It should be noted that a large angle of view refers to a side angle that deviates significantly from the direct angle of view, such as 30° to 89°.

[0061] The light-emitting unit 21 suffers from brightness reduction due to light blocking at large viewing angles. If the touch electrodes 51 are unevenly distributed, for example, fewer touch electrodes 51 are provided around the light-emitting units 21 of certain colors, while more touch electrodes 51 are provided around the light-emitting units 21 of other colors, color shift is likely to occur at large viewing angles. In this embodiment, a light-transmitting opening 42 and an isolation opening 41 are provided in the isolation structure 40. At least a portion of the outer periphery of the light-emitting unit 21 in the orthographic projection of the substrate 10 is surrounded by the orthographic projection of the touch electrodes 51 in the substrate 10. The orthographic projection of the light-transmitting opening 42 in the substrate 10 is located between the orthographic projection of the light-emitting unit 21 in the substrate 10 and the orthographic projection of the touch electrodes 51 in the substrate 10. This ensures that each light-emitting unit 21 has a touch electrode 51 on its outer periphery. The degree of brightness reduction caused by the touch electrodes 51 blocking the light of each light-emitting unit 21 at large viewing angles is approximately the same, reducing the degree of brightness attenuation of each light-emitting unit 21 at large viewing angles and reducing the color shift phenomenon of the display panel 100.

[0062] In some embodiments, the light-emitting unit layer 20 further includes a pixel definition layer 22, which includes a pixel defining portion 221 and a pixel opening 222 formed by the pixel defining portion 221, with the light-emitting unit 21 located within the pixel opening 222. The pixel defining layer can reduce crosstalk between the light-emitting units 21 and improve the display effect of the display panel 100.

[0063] The isolation opening 41 is provided in a one-to-one correspondence with the pixel opening 222, and the orthographic projection of the pixel opening 222 on the substrate 10 is located within the orthographic projection of the isolation opening 41 on the substrate 10. That is to say, an isolation unit is provided between every two adjacent light-emitting layers 212 in the display panel 100, which can prevent mutual interference between adjacent light-emitting units 21.

[0064] Alternatively, the isolation opening 41 may be correspondingly arranged with at least two pixel openings 222, and the orthographic projections of the at least two pixel openings 222 on the substrate 10 are all located within the orthographic projections of the corresponding isolation opening 41 on the substrate 10. The isolation opening 41 defined by the isolation structure 40 is correspondingly arranged with at least two pixel openings 222, meaning that multiple spaced-apart light-emitting layers 212 are disposed within the isolation opening 41, and no isolation structure 40 is disposed between two adjacent light-emitting layers 212 within this portion of the isolation opening 41. This design allows the density of the isolation structure 40 to be flexibly adjusted according to usage requirements. The size of the isolation opening 41 defined by the isolation structure 40 is larger than the size of the pixel opening 222; this design prevents the isolation structure 40 from blocking the light emitted by the light-emitting layers 212 in the pixel opening 222.

[0065] Preferably, the pixel definition layer 22 includes inorganic materials. For example, inorganic materials such as zinc oxide, indium tin oxide, silicon dioxide, and silicon can be used. The small molecule substances remaining after the film formation process using organic materials are prone to generating impurities, which is reflected in the increased out gas emission value. Inorganic materials have more stable chemical properties. Therefore, the pixel definition layer 22 in this embodiment can improve the stability of the display panel 100.

[0066] Optionally, the display panel 100 may further include an encapsulation layer 30, which is disposed on the side of the light-emitting unit layer 20 facing away from the substrate 10. The encapsulation layer 30 may include a first encapsulation sub-layer 31, a second encapsulation sub-layer 32, and a third encapsulation sub-layer 33 arranged sequentially in a direction away from the substrate 10. The first encapsulation sub-layer 31 and the third encapsulation sub-layer 33 may include inorganic materials such as silicon oxide, silicon nitride, or silicon oxynitride, while the second encapsulation sub-layer 32 may include organic materials. The first encapsulation sub-layer 31 can protect each light-emitting unit 21 from the influence of the external environment (such as air and water), preventing air and moisture from penetrating into the interior of the display panel 100, and extending the lifespan and stability of the light-emitting unit 21. The first encapsulation sub-layer 31 can also prevent impurities and harmful substances from entering the display panel 100, thereby ensuring the performance and quality of the display panel 100. The organic material of the second encapsulation sub-layer 32 has unique flexibility and good adhesion. Compared with inorganic materials, organic materials can better adapt to the slight deformations that the display panel 100 may undergo in different environments, and will not crack due to bending or thermal expansion and contraction of the panel. The combination of multiple encapsulation film layers, namely the first encapsulation sublayer 31, the second encapsulation sublayer 32, and the third encapsulation sublayer 33, further improves the encapsulation effect of the display panel 100.

[0067] like Figure 3 As shown, in some embodiments, the touch electrode 51 includes a plurality of touch sub-electrodes 511 extending in different directions.

[0068] Multiple touch sub-electrodes 511 extending in different directions can form an interlaced sensing network. When a user performs a touch operation, regardless of the touch direction, this network can capture the changes in physical quantities caused by the touch signal from multiple dimensions, such as changes in electric field and capacitance. Compared to electrode layouts with a single or fewer directions, this multi-directional design can more accurately locate the touch point, greatly improving the accuracy of touch detection. At the same time, since the various touch sub-electrodes 511 are interconnected, they form an integrated signal transmission system, which can effectively integrate and transmit the weak signals generated by the touch, thereby enhancing the sensitivity of touch detection. Even slight touch operations can be detected quickly and accurately.

[0069] The touch sub-electrodes 511 extending in different directions and interconnected can be more evenly distributed around the light-emitting unit 21. When viewed from a wide angle, this uniform distribution can make the degree of shading of each light-emitting unit 21 by the touch electrodes 51 more consistent, avoiding excessive differences in brightness attenuation of some light-emitting units 21 due to uneven distribution of the touch electrodes 51.

[0070] Please refer to the following: Figures 4-6 The display panel 100 includes a plurality of first converging regions H1, each of which includes touch sub-electrodes 511 extending in different directions and interconnected with each other. Each first converging region H1 includes a plurality of first converging sub-regions H11, each of which is the region between two adjacent touch sub-electrodes 511. At least one first converging sub-region H11 is provided with a light-transmitting opening 42.

[0071] A light-transmitting opening 42 can be provided in each of the first converging sub-regions H11 of the first converging region H1, or it can be provided in one or more of the first converging sub-regions H11. For example, if the first converging region H1 includes four first converging sub-regions H11, then a light-transmitting opening 42 can be provided in all four first converging sub-regions H11, that is, a total of four light-transmitting openings 42; or a light-transmitting opening 42 can be provided in one, two, or three of the first converging sub-regions H11.

[0072] Since the touch electrode 51 is composed of multiple touch sub-electrodes 511 extending in different directions and interconnected, the places where these touch sub-electrodes 511 intersect form a first confluence region H1. The first confluence region H1 can be further subdivided into multiple first confluence sub-regions H11, that is, local areas between adjacent connected touch sub-electrodes 511. "At least one first confluence sub-region H11 is provided with a light-transmitting opening 42" means that in the specific area formed by the intersection of these touch sub-electrodes 511, a portion of space is reserved as a light-transmitting opening 42. These light-transmitting openings 42 can provide a channel for light transmission, so that they can meet the light transmission requirements of functional components such as cameras and fingerprint sensors, and also balance the light blocking effect of the touch electrodes 51 during the display process.

[0073] In this embodiment, the light-transmitting opening 42 is set in the first confluence sub-region H11, so that the touch sub-electrode 511 can completely cover the outer periphery of the light-emitting unit 21 in other areas, maintaining uniform touch sensing and brightness attenuation control; on the other hand, setting the light-transmitting opening 42 in the first confluence sub-region H11 avoids openings directly above the light-emitting unit 21 or other key display areas, preventing problems such as dark areas and light leakage in the display screen caused by openings, and achieving a good balance between touch function and display effect.

[0074] Preferably, the orthographic projection of the light-transmitting opening 42 onto the substrate 10 is located within the orthographic projection of the first confluence region H11 onto the substrate 10, which can prevent the touch sub-electrode 511 from blocking the light-transmitting opening 42.

[0075] In some embodiments, the display panel 100 includes a first region and a second region, an isolation opening 41 is located at least in the first region, a light-transmitting opening 42 is located in the second region, and the light transmittance of the second region is greater than that of the first region.

[0076] Since the first region where the isolation opening 41 is located has low light transmittance requirements, the isolation opening 41 can be set in this region to better separate the light-emitting layers 212 of different light-emitting units 21, prevent crosstalk between light-emitting units 21, and improve the purity and color accuracy of the displayed image. Meanwhile, the high light transmittance of the second region ensures that light can pass smoothly through the light-transmitting opening 42, providing sufficient light transmission channels for functional components such as cameras and fingerprint sensors, ensuring their normal operation.

[0077] In some embodiments, the second region includes a plurality of light-transmitting units S11, each light-transmitting unit S11 including at least one light-transmitting opening 42, and the plurality of light-transmitting units S11 are respectively located in different first confluence regions H1.

[0078] By setting light-transmitting units S11 in different first confluence regions H1, the number of light-transmitting openings 42 can be increased, and more space in the second region can be used to set light-transmitting openings 42, thereby improving the light transmittance of the second region.

[0079] Preferably, each light-transmitting unit S11 includes a plurality of light-transmitting openings 42, and the plurality of light-transmitting openings 42 of each light-transmitting unit S11 are arranged in a one-to-one correspondence with the plurality of first converging sub-regions H11 of each first converging region H1.

[0080] Each first confluence sub-region H11 is provided with a light-transmitting opening 42, which increases the number of light-transmitting openings 42, improves the space utilization of the second region, and further improves the light transmittance of the second region.

[0081] Preferably, each light-transmitting unit S11 includes multiple light-transmitting openings 42, which are arranged at uniform intervals, so that light can pass through each light-transmitting opening 42 evenly and then reach the photosensitive element, thereby improving the uniformity and stability of light transmission.

[0082] Preferably, a plurality of light-transmitting units S11 are arranged at intervals around the outer periphery of the light-emitting unit 21.

[0083] Multiple first confluence regions H1 can be set along the outer periphery of each light-emitting unit 21. Each first confluence region H1 can be set with a corresponding light-transmitting unit S11. Multiple light-transmitting units S11 are arranged at intervals along the outer periphery of the light-emitting unit 21, which can increase the number of light-transmitting units S11 in a limited space, thereby improving the light transmittance of the second region.

[0084] like Figure 7 As shown, in some embodiments, the display panel 100 further includes a virtual electrode 512, which is insulated from the touch electrode 51.

[0085] The touch electrode 51 and the virtual electrode 512 can be formed using the same material and through the same process. The touch electrode 51 is connected to the touch signal, but the virtual electrode 512 is not connected to the touch signal. In locations where the touch electrode 51 must be removed, a virtual electrode 512 can be provided, ensuring that each light-emitting unit 21 has an electrode on its outer periphery. This guarantees that the light occlusion of different light-emitting units 21 is as uniform as possible at a wide viewing angle, meaning that the difference in brightness attenuation between different light-emitting units 21 is not significant, reducing color shift at wide viewing angles.

[0086] Preferably, the touch electrode 51 includes a first electrode 513 and a second electrode 514 that are disconnected, with a first gap X1 between the first electrode 513 and the second electrode 514, and the virtual electrode 512 is located in the first gap X1.

[0087] One of the first electrode 513 and the second electrode 514 can be a driving electrode, and the other can be a sensing electrode. The first electrode 513 and the second electrode 514 are insulated from each other by a first gap X1. The virtual electrode 512 is set in the first gap X1, making full use of the empty space of the first gap X1, so that the outer periphery of each light-emitting unit 21 can be evenly surrounded by the touch electrode 51 and the virtual electrode 512, thereby further reducing the color shift phenomenon at a large viewing angle.

[0088] In some embodiments, there is a gap between the orthographic projection of the virtual electrode 512 onto the substrate 10 and the orthographic projection of the light-transmitting opening 42 onto the substrate 10. The virtual electrode 512 does not block the light-transmitting opening 42 and does not affect the light transmittance of the light-transmitting opening 42.

[0089] Preferably, the orthographic projection of the virtual electrode 512 onto the substrate 10 does not overlap with the orthographic projection of the isolation opening 41. The virtual electrode 512 does not block the isolation opening 41 and does not affect the light emission efficiency of the light-emitting unit 21.

[0090] Preferably, the orthographic projection of the light-transmitting opening 42 onto the substrate 10 is located between the orthographic projection of the light-emitting unit 21 onto the substrate 10 and the orthographic projection of the virtual electrode 512 onto the substrate 10.

[0091] The setting of the light-transmitting opening 42 does not affect the arrangement space of the virtual electrode 512, so that each light-emitting unit 21 has a touch electrode 51 and a virtual electrode 512 on its outer periphery. Under a large viewing angle, the brightness reduction caused by the touch electrode 51 and the virtual electrode 512 blocking the light of each light-emitting unit 21 is about the same, which reduces the brightness attenuation of each light-emitting unit 21 under a large viewing angle and reduces the color shift phenomenon of the display panel 100.

[0092] In some embodiments, the virtual electrode 512 includes a plurality of virtual sub-electrodes 515 that extend in different directions and are interconnected.

[0093] The virtual sub-electrodes 515 extending in different directions and interconnected can have the same shape as the virtual touch sub-electrodes 511, so that the virtual electrodes 512 located in the gaps between the touch electrodes 51 are more evenly distributed on the outer periphery of the light-emitting unit 21. When viewed from a wide angle, this evenly distributed virtual electrodes 512 and touch electrodes 51 can make the degree of electrode occlusion of each light-emitting unit 21 tend to be consistent, avoiding excessive differences in brightness attenuation of some light-emitting units 21 due to uneven electrode distribution.

[0094] Preferably, the display panel 100 includes a second confluence region H2, which includes the confluence region of virtual sub-electrodes 515 extending in different directions. The second confluence region H2 includes a plurality of second confluence sub-regions H21, which are the regions between adjacent virtual sub-electrodes 515. At least one second confluence sub-region H21 is provided with a light-transmitting opening 42.

[0095] Similar to the first confluence region H11 of the touch electrode 51, the second confluence region H21 formed by the intersection of the virtual sub-electrodes 515 reserves some space as a light-transmitting opening 42. These light-transmitting openings 42 provide a channel for light transmission, satisfying the light transmission requirements of functional components such as the camera and fingerprint sensor, while also balancing the light-blocking effect of the touch electrode 51 during display. The second confluence region H21 allows the virtual sub-electrodes 515 to completely cover the outer periphery of the light-emitting unit 21 in other areas, maintaining uniform brightness attenuation control.

[0096] Preferably, the orthographic projection of the light-transmitting opening 42 onto the substrate 10 is located within the orthographic projection of the second confluence region H21 onto the substrate 10, which can prevent the virtual sub-electrode 515 from blocking the light-transmitting opening 42.

[0097] like Figure 8As shown, in some embodiments, the touch electrode 51 includes a first touch sub-electrode 516 and a second touch sub-electrode 517, and the virtual electrode 512 includes a first virtual sub-electrode 518 and a second virtual sub-electrode 519 arranged in a cross configuration. A second gap X2 is formed between the first touch sub-electrode 516 and the first virtual sub-electrode 518, and a second gap X2 is formed between the second touch electrode 517 and the second virtual sub-electrode 519.

[0098] The second gap X2 ensures good insulation between the touch electrode 51 and the virtual electrode 512, effectively avoiding signal crosstalk and preventing touch failure, accidental touch and other problems caused by signal interference between electrodes.

[0099] Preferably, the first virtual sub-electrode 518 extends in the same direction as the first touch sub-electrode 516.

[0100] When the first virtual sub-electrode 518 extends in the same direction as the corresponding first touch sub-electrode 516, they can be more evenly distributed around the outer periphery of the light-emitting unit 21. When viewing the display panel 100 at a wide viewing angle, the degree to which each light-emitting unit 21 is blocked by the electrodes will be more consistent. This effectively avoids excessive brightness decay of some light-emitting units 21 due to irregular electrode distribution, thereby reducing the difference in brightness decay of different light-emitting units 21 at wide viewing angles and reducing color shift of the display panel 100.

[0101] Preferably, the second virtual sub-electrode 519 extends in the same direction as the second touch sub-electrode 517.

[0102] Similarly, when the second virtual sub-electrode 519 and the second touch sub-electrode 517 extend in the same direction, they can be more evenly distributed around the outer periphery of the light-emitting unit 21. When viewing the display panel 100 at a wide viewing angle, the degree to which each light-emitting unit 21 is blocked by the electrodes will be more consistent. This effectively avoids excessive brightness decay of some light-emitting units 21 due to irregular electrode distribution, thereby reducing the difference in brightness decay of different light-emitting units 21 at wide viewing angles and reducing color shift of the display panel 100.

[0103] In some embodiments, the virtual electrode 512 includes a first virtual sub-electrode 518 and a second virtual sub-electrode 519 arranged in a cross configuration. The projection of a portion of the light-transmitting opening 42 onto the substrate 10 is located between the projection of the first virtual sub-electrode 518 onto the substrate 10 and the projection of the light-emitting unit 21 onto the substrate 10. The projection of a portion of the light-transmitting opening 42 onto the substrate 10 is located between the projection of the second virtual sub-electrode 519 onto the substrate 10 and the projection of the light-emitting unit 21 onto the substrate 10.

[0104] Neither the first virtual sub-electrode 518 nor the second virtual sub-electrode 519 will affect the light transmittance of the light-transmitting opening 42, and the setting of the light-transmitting opening 42 will not affect the setting of the virtual sub-electrode 515. This makes the electrode arrangement on the periphery of each light-emitting unit 21 more uniform. The degree of brightness reduction caused by blocking the light of each light-emitting unit 21 at a large viewing angle is about the same, which reduces the degree of brightness attenuation of each light-emitting unit 21 at a large viewing angle and reduces the color shift phenomenon of the display panel 100.

[0105] like Figure 9 As shown, preferably, the virtual electrode 512 further includes a third virtual sub-electrode 520, the orthographic projection of the third virtual sub-electrode 520 on the substrate 10 being located between the orthographic projection of the light-transmitting opening 42 on the substrate 10 and the orthographic projection of the light-emitting unit 21 on the substrate 10.

[0106] This embodiment further utilizes the gap between the light-transmitting opening 42 and the light-emitting unit 21 to increase the area of ​​the virtual electrode 512, which can further homogenize the electrode distribution around the light-emitting unit 21. When viewed from a wide viewing angle, the degree of electrode occlusion of each light-emitting unit 21 becomes more consistent, effectively reducing the difference in brightness attenuation caused by insufficient local electrode coverage. The setting of the third virtual sub-electrode 520 cleverly utilizes the gap between the light-transmitting opening 42 and the light-emitting unit 21, increasing the electrode area without obstructing the light transmission path of the light-transmitting opening 42. This allows light to efficiently pass through the display panel 100 to reach functional components such as the camera and fingerprint sensor.

[0107] Preferably, the third virtual sub-electrode 520 is arranged around the outer periphery of the first virtual sub-electrode 518 and the second virtual sub-electrode 519.

[0108] The third virtual sub-electrode 520 is arranged around the first virtual sub-electrode 518 and the second virtual sub-electrode 519, which can further improve the coverage of the virtual electrode 512 on the periphery of the light-emitting unit 21, forming a denser and more uniform electrode network. When viewed from a wide viewing angle, the degree of electrode occlusion of each light-emitting unit 21 becomes more consistent, avoiding differences in brightness attenuation caused by uneven electrode distribution and reducing color shift in the display panel 100. While increasing the area of ​​the virtual electrode 512, it does not obstruct the light-transmitting opening 42, ensuring that light can pass smoothly through the display panel 100 to reach functional components such as the camera and fingerprint sensor.

[0109] In some embodiments, the light-emitting unit 21 includes a first light-emitting unit 214, a second light-emitting unit 215, and a third light-emitting unit 216, each emitting a different color. At least a portion of the outer periphery of the first light-emitting unit 214, the second light-emitting unit 215, and the third light-emitting unit 216 projected onto the substrate 10 is surrounded by the touch electrode 51 projected onto the substrate 10. The fact that the three light-emitting units 21 with different colors are all surrounded by the touch electrode 51 ensures that the degree of electrode occlusion of each light-emitting unit 21 is similar at a wide viewing angle.

[0110] In some embodiments, as the viewing angle increases, the brightness decay rate of the light emitted by the first light-emitting unit 214 is less than that of the light emitted by the second light-emitting unit 215 and the third light-emitting unit 216, respectively. The projected area of ​​the touch electrode 51 on the substrate 10 of the outer periphery of the first light-emitting unit 214 is greater than that of the projected area of ​​the touch electrode 51 on the substrate 10 of the outer periphery of the second light-emitting unit 215 and the third light-emitting unit 216, respectively.

[0111] As the viewing angle increases, the brightness decay rate of the light emitted by the first light-emitting unit 214 is less than that of the light emitted by the second light-emitting unit 215 and the third light-emitting unit 216. In other words, at a large viewing angle, the decay rate of the first light-emitting unit 214 is smaller, while the decay rates of the second and third light-emitting units 215 and 216 are larger. This results in the first light-emitting unit 214 having higher brightness, while the second and third light-emitting units 215 and 216 have relatively lower brightness. Consequently, for a white light emitted at a normal viewing angle, the user sees a greater intensity of light emitted by the first light-emitting unit 214 than light emitted by the second and third light-emitting units 215 at the same large viewing angle. That is, a white image appears more biased towards the color emitted by the first light-emitting unit 214 at a large viewing angle.

[0112] For example, the first light-emitting unit 214 is a green light-emitting unit that emits green light, the second light-emitting unit 215 is a blue light-emitting unit that emits blue light, and the third light-emitting unit 216 is a red light-emitting unit that emits red light. Because the materials of the green light-emitting unit in this embodiment are different from those of the blue and red light-emitting units, the green light-emitting unit has the slowest brightness decay rate as the viewing angle increases, resulting in a greenish tint on the display panel 100 at wide viewing angles.

[0113] This application embodiment addresses the differences in brightness decay rates among different light-emitting units 21 by increasing the projected area of ​​the touch electrode 51 on the periphery of the first light-emitting unit 214 (e.g., the green light-emitting unit 21), which has a slower brightness decay, thereby increasing its light-blocking effect. Simultaneously, it reduces the projected area of ​​the touch electrode 51 on the periphery of the second light-emitting unit 215 and the third light-emitting unit 21 (e.g., the blue and red light-emitting units 21), which have faster brightness decay, thereby reducing light-blocking. This differentiated design effectively balances the brightness output of each light-emitting unit 21 at wide viewing angles, preventing a single color light-emitting unit 21 from excessively dominating the image color due to its brightness advantage, thus correcting the color shift problem of white images at wide viewing angles.

[0114] like Figure 10 As shown, in some embodiments, the shape of the light-transmitting opening 42 projected onto the substrate 10 is circular, triangular, or elliptical.

[0115] The circular light-transmitting opening 42 has a symmetrical edge structure in all directions, resulting in relatively uniform refraction and scattering of light as it passes through, minimizing light loss and ensuring stable and sufficient light for functional components such as cameras and fingerprint sensors. The triangular light-transmitting opening 42, with its sharp corners, guides the direction of light, enabling directional light transmission in specific optical designs and improving light utilization efficiency. The elliptical light-transmitting opening 42, with its different characteristics along its major and minor axes, can flexibly adapt to the light acquisition angle and range requirements of different functional components, allowing light to reach the photosensitive element more accurately and improving the performance of these components.

[0116] Secondly, this application embodiment also provides a display panel 100, including a substrate 10, an isolation structure 40, a light-emitting unit layer 20, and a touch layer 50; the isolation structure 40 is disposed on one side of the substrate 10 and has a light-transmitting opening 42 and an isolation opening 41, the isolation opening 41 being at least located in a first region, and the light-transmitting opening 42 being located in a second region; the light-emitting unit layer 20 is disposed on one side of the substrate 10, and the light-emitting unit layer 20 includes a plurality of spaced light-emitting units 21, the orthographic projection of the light-emitting units 21 on the substrate 10 being located within the orthographic projection of the isolation opening 41 on the substrate 10; the touch layer 50 is disposed on the side of the light-emitting unit layer 20 away from the substrate 10, and the touch layer 50 includes touch electrodes 51, at least a portion of the outer periphery of the orthographic projection of each light-emitting unit 21 on the substrate 10 is surrounded by the orthographic projection of the touch electrodes 51 on the substrate 10. The display panel 100 includes a plurality of first confluence regions H1, each of which includes touch sub-electrodes 511 extending in different directions and interconnected with each other. Each first confluence region H1 includes a plurality of first confluence sub-regions H11, and each first confluence region H11 is the area between two adjacent touch sub-electrodes 511. At least one first confluence sub-region H11 is provided with a light-transmitting opening 42.

[0117] Thirdly, this application embodiment also provides a method for manufacturing a display panel 100, including the following steps:

[0120] S30. A touch layer 50 is formed on the side of the light-emitting unit layer 20 away from the substrate 10. The touch layer 50 includes a touch electrode 51.

The orthographic projection of the light-transmitting opening 42 onto the substrate 10 is located between the orthographic projection of the light-emitting unit 21 onto the substrate 10 and the orthographic projection of the touch electrode 51 onto the substrate 10.
