[0046] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0047] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0048] With the development of technology, users have increasingly higher requirements for the performance of display devices, such as screen-to-body ratio. To achieve a high screen-to-body ratio, HIAA (Hole-In Active Area) technology is commonly used. HIAA technology places the phone's camera below the display panel, and this area is not displayed, which is the punch-hole screen commonly seen on the market today.

[0049] Reference Figure 1 , Figure 2As shown, in related technologies, the display panel 100 includes an aperture area 101, a transition area 102, and a display area 103 (Active Area, abbreviated as AA area). The aperture area 101 is located within the display area 103, and the transition area 102 is located between the aperture area 101 and the display area 103. A dummy pixel is disposed within the aperture area 101. The dummy pixel has the same circuit structure as the normal pixel in the display area; for example, the dummy pixel includes a driving circuit layer, which includes transistors, capacitors, and signal lines. Since the dummy pixel does not directly participate in image display, its driving circuit layer is usually not connected to a power supply voltage. Therefore, the dummy pixel located in the aperture area is in a floating state, which is not conducive to static electricity discharge and may cause electrostatic discharge damage, leading to defects. In other words, because the dummy pixel in the aperture area 101 is in a floating state, static electricity is easily accumulated during the manufacturing process, which can damage the circuits and components.

[0050] Based on this, this application provides a display panel that uses a fixed voltage signal to avoid damage to circuits and components caused by static electricity during manufacturing. See the following embodiments for details.

[0051] Reference Figure 3 , Figure 4 , Figure 5 As shown, some embodiments of this application provide a display panel 100, which includes an opening area 101, a transition area 102 and a display area 103. The display area 103 at least partially surrounds the opening area 101, and the transition area 102 is located between the opening area 101 and the display area 103.

[0052] The display panel 100 also includes a plurality of virtual pixels 11 located in the opening area 101, and the virtual pixels 11 are configured with fixed voltage signals.

[0053] The display panel 100 provided in this application, by configuring a fixed voltage signal on the virtual pixel 11, makes the potential of the virtual pixel stable after receiving the fixed voltage signal, avoids the virtual pixel being in a floating state, thereby avoiding static electricity accumulation in the process, and thus improving circuit stability and display reliability, and improving product yield.

[0054] Specifically, the display panel 100 may include multiple pixel driving circuits located in the display area 103. The pixel driving circuits may include multiple transistors and capacitors, forming various forms such as 2T1C (i.e., 2 transistors and 1 capacitor), 3T1C, or 7T1C.

[0055] Taking 7T1C as an example, refer to Figure 5As shown, the pixel driving circuit includes a first transistor T1, a second transistor T2, a third transistor T3, a fourth transistor T4, a fifth transistor T5, a sixth transistor T6, and a seventh transistor T7. The pixel driving circuit also includes a light-emitting module (OLED) and a capacitor Cst. Specifically, the first terminal of the first transistor T1 is connected to the first power supply signal ELVDD; the control terminals of the fifth transistor T5 and the sixth transistor T6 are connected to the light emission control signal EM; and the cathode of the OLED is connected to the second power supply signal ELVSS. The first terminal of the second transistor T2 is connected to the data voltage signal Vdata; the second terminal of the second transistor T2 is connected to the first terminal of the first transistor T1; and the control terminal of the second transistor T2 is connected to the second scan signal SCAN2. The first terminal of the third transistor T3 is connected to the second terminal of the first transistor T1; the second terminal of the third transistor T3 is connected to the control terminal of T1; and the control terminal of the third transistor T3 is connected to the second scan signal SCAN2. The first terminal of the fourth transistor T4 is connected to the control terminal of the first transistor T1; the second terminal of the fourth transistor T4 is connected to the reference signal Vref; and the control terminal of the fourth transistor T4 is connected to the first scan signal SCAN1. The first terminal of the fifth transistor T5 is connected to the first power supply signal ELVDD, and the second terminal of the fifth transistor T5 is connected to the first terminal of the first transistor T1. The first terminal of the sixth transistor T6 is connected to the second terminal of the first transistor T1, and the second terminal of the sixth transistor T6 is connected to the anode of the OLED module. The first terminal of the seventh transistor T7 is connected to the reference signal Vref, the second terminal of the seventh transistor T7 is connected to the anode of the OLED module, and the control terminal of the seventh transistor T7 is connected to the first scan signal SCAN1.

[0056] The fixed voltage signal in this application is the first power supply signal ELVDD. In the display area 103, the corresponding pixel driving circuit can control the display state of the OLED module through the first power supply signal ELVDD.

[0057] Specifically, the opening area 101 refers to the HIAA (Hole-In Active Area) region, which can be located anywhere in the display area 103. Functional components such as cameras and sensors can be installed within the opening area 101 to enable the display panel 100 to take pictures or perform other sensing functions. During the manufacturing process, the display panel 100 is cut at a predetermined location to form the opening area 101. Multiple isolation pillars can be provided in the transition area 102, spaced apart from each other and surrounding the opening area 101 at least once, to isolate the opening area 101 from the display area 103 and prevent moisture intrusion. Additionally, signal wiring can be installed in the transition area 102.

[0058] In this embodiment, the outline shape of the opening area 101 is circular, such as... Figure 4 As shown. It is understood that in other embodiments, the outline shape of the opening area 101 is not limited to this, and may also be an ellipse, a square, a rhombus, or other polygons or any other arbitrary shape.

[0059] In this embodiment, the entire aperture area 101 is located within the display area 103, that is, the aperture area 101 is surrounded by the transition area 102 and the display area 103. In other embodiments, the aperture area 101 may also be partially located within the display area 103, that is, the boundary of the aperture area 101 coincides with a portion of the boundary of the display area 103, and the aperture area 101 is partially surrounded by the transition area 102 and the display area 103.

[0060] Reference Figure 6 As shown, in some embodiments, the display panel 100 further includes a first signal line 12 for providing a fixed voltage signal, and the virtual pixel 11 is connected to the first signal line 12.

[0061] The first signal line 12 is used to input a fixed voltage signal to the virtual pixel 11. By connecting the fixed voltage signal, the floating state of the virtual pixel and the problem of static electricity in the manufacturing process can be effectively avoided, the stability of the electrical connection can be enhanced, and the reliability of the display panel 100 and the stability of the manufacturing process can be improved.

[0062] Specifically, the first signal line 12 is a first power supply line that provides voltage to the pixel driving circuit. Power supply voltage can be transmitted to the pixel driving circuit in the display area 103 through the first signal line 12.

[0063] Specifically, the first signal line 12 can be located in the border area outside the display area 103, and both the border area and the opening area 101 belong to the non-display area.

[0064] Reference Figure 6 As shown, in some embodiments, the display panel 100 further includes a substrate 10 and an electrostatic shielding layer 13. The electrostatic shielding layer 13 is located on one side of the substrate 10 and is connected to the first signal line 12. The virtual pixel 11 includes a driving circuit layer 15, which is located on the side of the electrostatic shielding layer 13 away from the substrate 10 and is electrically connected to the electrostatic shielding layer 13.

[0065] Preferably, the electrostatic shielding layer 13 is electrically connected to at least one first signal line 12 in the drive circuit layer 15.

[0066] Preferably, the electrostatic shielding layer 13 is electrically connected to all the first signal lines 12 in the drive circuit layer 15.

[0067] The electrostatic shielding layer 13 is located between the substrate 10 and the driving circuit layer 15. The signal lines in the driving circuit layer 15 are electrically connected to the first signal line 12 through the electrostatic shielding layer 13, so that the signal lines of the virtual pixel 11 have the same potential as the first power supply signal ELVDD, such as a high-level fixed potential. By fixing the potential, the floating of the ports of the peripheral virtual pixels 11 can be avoided, which can improve the anti-static capability of the corresponding virtual pixels 11, thereby reducing the impact of static charge on the performance of the display panel 100.

[0068] Specifically, a display function layer is provided on the side of the driving circuit layer 15 away from the substrate 10. The display function layer may include a pixel definition layer and a plurality of light-emitting devices defined by the pixel definition layer. The light-emitting devices include an anode, a light-emitting function layer and a cathode stacked sequentially on the driving circuit layer 15. For example, the light-emitting function layer may include a light-emitting layer, and may further include one or more of hole injection layer, hole transport layer, organic light-emitting layer, electron transport layer, electron injection layer, etc. For example, it may further include one or more of hole blocking layer, electron blocking layer, etc.

[0069] Preferably, the display panel further includes an insulating layer 14, which is located between the electrostatic shielding layer 13 and the driving circuit layer 15, and the driving circuit layer 15 and the electrostatic shielding layer 13 are electrically connected through a via in the insulating layer 14.

[0070] Preferably, the electrostatic shielding layer 13 is electrically connected to at least one signal line in the drive circuit layer 15 through a via in the insulating layer 14.

[0071] Preferably, the electrostatic shielding layer 13 is electrically connected to all signal lines in the drive circuit layer 15 through vias in the insulating layer 14.

[0072] Specifically, since the driving circuit layer 15 and the electrostatic shielding layer 13 are disposed in different layers, the driving circuit layer 15 and the electrostatic shielding layer 13 located in the aperture area 101 can be electrically connected using a wire-swapping technique. This also reduces the area of ​​the non-display area projected onto the substrate 10, effectively reducing the screen-to-body ratio of the non-display area and helping to improve the visual experience.

[0073] Reference Figure 7 , Figure 8 As shown, in some embodiments, the electrostatic shielding layer 13 includes a first connection structure 131, a second connection structure 132, and a third connection structure 133. The first connection structure 131 is located in the opening area 101, and the outermost virtual pixels 11 are connected through the first connection structure 131. The second connection structure 132 is located in the display area 103 and is connected to the first signal line 12. The third connection structure 133 is located in the transition area 102 and connects the first connection structure 131 and the second connection structure 132.

[0074] Preferably, the electrostatic shielding layer 13 includes a metal layer, and the first connection structure 131, the second connection structure 132, and the third connection structure 133 are located in the metal layer.

[0075] Specifically, the virtual pixel 11 is connected to the first connection structure 131. The first connection structure 131 forms a continuous conductive network of conductive metals from all the virtual pixels 11, increasing conductivity throughout the aperture area 101 and ensuring electrical connection stability. By providing vias in the film layer (e.g., the insulating layer) between the electrostatic shielding layer 13 and the layer containing the first signal line 12, the connection between the electrostatic shielding layer 13 and the first signal line 12 is achieved. The first power signal on the first signal line 12 is transmitted to the second connection structure 132, the third connection structure 133, and the first connection structure 131 in the electrostatic shielding layer 13, reaching the virtual pixel 11, thus forming a complete conductive loop. This provides a stable electrical connection for the virtual pixel 11 in the aperture area 101, preventing the virtual pixel 11 from floating and thus avoiding process electrostatic problems.

[0076] Reference Figure 8 As shown, in some embodiments, the first connection structure 131 connects the outermost virtual pixels 11 to form a first ring structure.

[0077] Correspondingly, the aperture area 101 is entirely located in the display area 103, and the metal lines of all virtual pixels 11 within the aperture area 101 are electrically connected through the first connection structure 131 to form a grid-like structure.

The second connection structure 132 is arranged around the opening area 101 and the transition area 102. The second connection structure 132 can form a ring-shaped conductive path to receive the first power signal and transmit the signal to the connected virtual pixel.

[0080] Reference Figure 8 As shown, in some embodiments, the third connection structure 133 includes a connecting wire, one end of which is connected to the first connection structure 131 and the other end of which is connected to the second connection structure 132.

[0081] Reference Figure 8As shown, in some embodiments, a plurality of third connection structures 133 are provided between the first connection structure 131 and the second connection structure 132.

[0082] Preferably, a plurality of third connecting structures 133 are distributed circumferentially at intervals on the first connecting structure 131.

[0083] In some embodiments, a plurality of third connection structures 133 are evenly distributed circumferentially in the first connection structure 131.

[0084] Specifically, multiple third connection structures 133 are arranged around the first connection structure 131 in the transition region 102 and connected to the second connection structure 132, jointly accessing a continuous conductive network.

[0085] Other embodiments of this application provide a display device including the display panel 100 described in the above embodiments. Specifically, the display panel 100 includes an opening area 101, a transition area 102, and a display area 103, wherein the display area 103 at least partially surrounds the opening area 101, and the transition area 102 is located between the opening area 101 and the display area 103. The display panel 100 also includes a plurality of virtual pixels 11 located within the opening area 101, and each virtual pixel 11 is configured with a fixed voltage signal.

[0086] The display device provided in this application has a display panel 100 that has a fixed voltage signal configured on the virtual pixels 11. This makes the virtual pixels have a stable potential after receiving the fixed voltage signal, avoiding them from being in a floating state. This avoids the accumulation of static electricity in the manufacturing process, thereby improving circuit stability and display reliability, and increasing product yield.

[0087] In some embodiments, the display panel 100 further includes a first signal line 12 for providing a fixed voltage signal, and the virtual pixel 11 is connected to the first signal line 12.

[0088] In some embodiments, the display panel 100 further includes a substrate 10 and an electrostatic shielding layer 13, the electrostatic shielding layer 13 being located on one side of the substrate 10 and connected to the first signal line 12. The virtual pixel 11 includes a driving circuit layer 15, the driving circuit layer 15 being located on the side of the electrostatic shielding layer 13 away from the substrate 10, and the driving circuit layer 15 being connected to the electrostatic shielding layer 13.

[0089] The electrostatic shielding layer 13 is located between the substrate 10 and the driving circuit layer 15. The electrostatic shielding layer 13 is electrically connected to the first signal line 12, so that the electrostatic shielding layer 13 has the same potential as the first power signal ELVDD, thereby reducing the impact of static charge on the performance of the display panel 100.

[0090] Preferably, the display panel 100 further includes an insulating layer 14, which is located between the electrostatic shielding layer 13 and the driving circuit layer 15, and the driving circuit layer 15 and the electrostatic shielding layer 13 are connected through a via in the insulating layer 14.

[0091] Specifically, since the driving circuit layer 15 and the electrostatic shielding layer 13 are arranged in different layers, the driving circuit layer 15 and the electrostatic shielding layer 13 located in the opening area 101 are electrically connected by a wire-swapping technique.

[0092] In some embodiments, the electrostatic shielding layer 13 includes a first connection structure 131, a second connection structure 132, and a third connection structure 133.

The third connection structure 133 is located in the transition area 102, and the third connection structure 133 connects the first connection structure 131 and the second connection structure 132.

[0093] Specifically, the virtual pixel 11 is connected to the first connection structure 131. The first connection structure 131 forms a continuous conductive network of conductive metals from all the virtual pixels 11, increasing conductivity throughout the opening area 101 and ensuring the stability of the electrical connection. By providing vias in the film layer (e.g., the insulating layer) between the electrostatic shielding layer 13 and the layer containing the first signal line 12, the connection between the electrostatic shielding layer 13 and the first signal line 12 is achieved. The first power signal on the first signal line 12 is transmitted to the second connection structure 132, the third connection structure 133, and the first connection structure 131 in the electrostatic shielding layer 13, reaching the virtual pixel 11, thus forming a complete conductive loop. This prevents the virtual pixel 11 from floating and avoids process electrostatic problems.

[0094] In some embodiments, the first connection structure 131 connects the outermost virtual pixels 11 to form a first ring structure. The second connection structure 132 is a second ring structure surrounding the first connection structure 131. That is, the first ring structure is located inside the second ring structure.
