Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of display, and in particular, to a display panel and a display device. Background Art

[0002] Current display panels are developing towards full-screen displays. In full-screen displays, a transparent display area with relatively high light transmittance is required within the display area to accommodate structures such as cameras. To ensure the transmittance of the transparent display area, only light-emitting devices can be provided within the transparent display area, and pixel circuits can be provided in the transition area surrounding the transparent display area to provide drive signals for the light-emitting devices within the transparent display area. Pixel units are also provided within the transition area for display in the transition area, where the pixel units include light-emitting devices and pixel circuits. Due to manufacturing process limitations of display panels, the number of pixel circuits that can be provided in the transition area is limited when the area of ​​the transition area remains unchanged. When there are many light-emitting devices in the transparent display area, the number of pixel circuits required for the transparent display area is relatively large. In this case, multiple light-emitting devices in the transparent display area can be connected to a single pixel circuit in the transition area, so that one pixel circuit can drive multiple light-emitting devices to emit light, thereby reducing the number of pixel circuits required for the transparent display area. In this case, the multiple light-emitting devices in the transparent display area receive the same drive current, which is equivalent to merging multiple pixel units in the transparent display area. This reduces the actual pixel density of the transparent display area, resulting in a display effect in the transparent display area that differs from that in the conventional display area, thereby reducing the overall display quality of the display panel.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0030] Figure 1 This is a schematic diagram of the structure of a display panel provided by the prior art. Figure 1 As shown, the display panel includes a conventional display area 101, a transition area 102, and a transparent display area 103. The transition area 102 is arranged around the transparent display area 103, and the conventional display area 101 is arranged around the transition area 102. Because the conventional display area 101 surrounds the transparent display area 103, the display panel can form an offshore full-screen display panel. The transparent display area 103 is provided with a light-emitting device, the conventional display area 101 is provided with a pixel unit, and the transition area 102 is provided with a pixel unit and a pixel circuit for driving the light-emitting device in the transparent display area 103. The pixel unit includes a light-emitting device and a pixel circuit for driving the light-emitting device. Because the transition area 102 requires additional pixel circuits corresponding to the light-emitting device in the transparent display area 103, the area of ​​the transition area 102 used to set up the pixel circuits corresponding to the light-emitting device in the transparent display area 103 is relatively small when the area of ​​the transition area 102 remains unchanged. As a result, the number of pixel circuits corresponding to the light-emitting device in the transparent display area 103 that can be set up in the transition area 102 is relatively small.

[0031] The pixel density within the transparent display area 103 can be equal to the pixel density within the conventional display area 101. That is, the number of pixels per unit area within the transparent display area 103 is equal to the number of pixels within the conventional display area 101, thereby ensuring display consistency between the transparent display area 103 and the conventional display area 101. The pixel density of the transparent display area 103 can be the number of light-emitting devices per unit area within the transparent display area 103. In this case, there are many light-emitting devices within the transparent display area 103, and the number of pixel circuits required is also relatively large, resulting in insufficient space within the transition area 102 for arranging pixel circuits and signal lines. In this case, multiple light-emitting devices in the transparent display area 103 can be connected to a single pixel circuit in the transition area 102, allowing one pixel circuit to drive multiple light-emitting devices to emit light, thereby reducing the number of pixel circuits required within the transparent display area 103. When multiple light-emitting devices in the transparent display area 103 correspond to one pixel circuit, the multiple light-emitting devices correspond to the same driving current, which is equivalent to the multiple light-emitting devices in the transparent display area 103 and one pixel circuit forming a pixel unit, thereby reducing the actual pixel density of the transparent display area 103, resulting in different pixel densities between the transparent display area 103 and the conventional display area 101, thereby making the display effect of the transparent display area 103 different from that of the conventional display area 101, thereby reducing the overall display effect of the display panel.

[0032] In response to the above technical problems, an embodiment of the present invention provides a display panel. Figure 2 Schematic diagram of the structure of a display panel provided by an embodiment of the present invention. Figure 2 As shown, the display panel includes a first display area 110, a second display area 120 and a non-display area 130; the second display area 120 at least partially surrounds the first display area 110, and the non-display area 130 at least partially surrounds the second display area 120; the first display area 110 is provided with a plurality of first light-emitting units 111, the non-display area 130 is provided with at least one first pixel unit 131, the second display area 120 is provided with a second pixel unit 121 and a signal line 122, the first pixel unit 131 and at least one second pixel unit 121 include a first pixel P1; the first pixel P1 is connected to the first light-emitting unit 111, and the signal line 122 is connected to the first pixel P1 in the second pixel unit 121; at least one second pixel unit 121 includes a first virtual pixel P0, the first virtual pixel P0 includes a first connection line L1, and at least one signal line 122 is connected to the first pixel P1 in the first pixel unit 131 through the first connection line L1.

[0033] Specifically, the display panel may be a full-screen display panel. The second display area 120 may be a regular display area of ​​the display panel, or may be called the main screen of the display panel. The first display area 110 may be a sub-screen of the display panel. For example, the first display area 110 may be in a circular, teardrop, or U-shaped shape. Figure 2 The first display area 110 is exemplarily shown as a rectangle. In addition, the second display area 120 completely surrounds the first display area 110, so that the display panel forms an offshore full-screen display panel. Only the first light-emitting unit 111 can be set in the first display area 110 to ensure the transmittance of the first display area 110, so that a photosensitive element can be set at a position opposite to the first display area 110 to realize under-screen photosensitivity of the display panel, and then realize full-screen display of the display panel. Exemplarily, the photosensitive element can be a camera, which can realize under-screen photography of the display panel. The non-display area 130 can be the border area of ​​the display panel.

[0034] In addition, the first light-emitting unit 111 can be a light-emitting device. For example, the first light-emitting unit 111 can be an organic light-emitting diode (OLED). A first pixel unit 131 is provided in the non-display area 130. The first pixel unit 131 includes a first pixel P1. The first pixel P1 can be connected to the first light-emitting unit 111 in the first display 110 to drive the first light-emitting unit 111 to emit light. A plurality of second pixel units 121 are provided in the second display area 120, and at least two second pixel units 121 include different pixels. For example, at least one second pixel unit 121 includes a first pixel P1, and at least one second pixel unit 121 includes a first virtual pixel P0. The first virtual pixel P0 can be provided in the same layer as the first pixel P1. When the first pixel P1 is also provided in at least one second pixel unit 121, the first pixel P1 can also be connected to the first light-emitting unit 111 in the first display 110 to drive the first light-emitting unit 111 to emit light. The first display area 110 has a plurality of first light-emitting units 111, each of which is connected to a corresponding first pixel P1. The first pixels P1 can include first pixels P1 within the first pixel unit 131 and first pixels P1 within the second pixel unit 121, so that each first pixel P1 can independently drive a first light-emitting unit 111 to emit light. This allows the pixel density of the first display area 110 to be equal to the number of first light-emitting units 111 per unit area. By arranging some first pixels P1 in the non-display area 130, the space occupied by the first pixels P1 in the second display area 120 can be reduced. This allows the number of first pixels P1 to be adjusted based on display requirements, which helps improve the pixel density of the first display area 110 and thus improve the display consistency between the first and second display areas 110, thereby enhancing the overall display quality of the display panel. For example, the number of first light-emitting units 111 can be adjusted based on display requirements so that the pixel density of the first display area 110 is equal to the pixel density of the second display area 120. At the same time, the number of first pixels P1 corresponding to the first light-emitting units 111 is set in the non-display area 130 and the second display area 120 respectively, so that the number of first pixels P1 is equal to the number of first light-emitting units 111, thereby improving the consistency of the display effects of the first display area 110 and the second display area 120, and improving the overall display effect of the display panel.

[0035] At the same time, signal lines 122 are provided within the second display area 120. Signal lines 122 are used to provide operating signals to the pixels. For example, signal lines 122 may include data lines for providing data signals to a column of pixels. Signal lines 122 may also include scan lines for providing scan signals to a row of pixels. Signal lines 122 may also include light-emission control signal lines for providing light-emission control signals to a row of pixels. When a first pixel P1 is provided within the non-display area 130, signal lines 122 may be connected to first connection lines L1 within the first virtual pixel P0 and extend to the non-display area 130 via first connection lines L1 to provide operating signals to the first pixel units 131 within the non-display area 130. This ensures normal operation of the first pixel P1 within the first pixel units 131 within the non-display area 130 while avoiding changes in the driving mode. Furthermore, different second pixel units 121 may include either the first pixel P1 or the first virtual pixel P0, which helps improve the consistency of the aperture ratios of different second pixel units 121 and further improves the display consistency of the display panel. Furthermore, the first connection line L1 is disposed in the first virtual display P0 to prevent the signal line 122 from occupying the space between the second pixel units 121 when winding, thereby simplifying the arrangement of the second pixel units 121 in the second display area 120 .

[0036] It should be noted that when the first light-emitting unit 111 includes multiple light-emitting devices emitting different colors, the first pixel unit 131 and the second pixel unit 121 may include multiple first pixels P1, each of which corresponds to a light-emitting device. For example, if the first light-emitting unit 111 includes a red light-emitting device, a green light-emitting device, and a blue light-emitting device, the first pixel unit 131 and the second pixel unit 121 may include three first pixels P1, each of which corresponds to a light-emitting device of a corresponding color, for driving the light-emitting device to emit light.

[0037] The technical solution of this embodiment comprises a first pixel unit disposed in a non-display area, the first pixel unit comprising a first pixel, and a second pixel unit disposed in a second display area, at least one of the second pixel units also comprising a first pixel. The first pixel is connected to the first light-emitting unit to drive the first light-emitting unit to emit light. By locating some of the first pixels in the non-display area, the number of first pixels disposed in the second display area can be reduced, reducing the space occupied by the first pixels in the second display area. This allows the number of first pixels to be adjusted according to display requirements, thereby improving the pixel density in the first display area and thereby enhancing the consistency of the display effects between the first and second display areas, thereby improving the overall display quality of the display panel. Furthermore, at least one of the second pixel units comprises a first dummy pixel. The first connecting line within the first dummy pixel can extend the signal line into the non-display area, allowing the signal line to drive the first pixel in the non-display area to operate normally without changing the driving mode. Furthermore, different second pixel units can comprise either the first pixel or the first dummy pixel, thereby improving the consistency of the aperture ratios of different second pixel units and further enhancing the display consistency of the display panel. Furthermore, the signal line can be prevented from occupying the space between the second pixel units during routing, thereby simplifying the arrangement of the second pixel units in the second display area.

[0038] On the basis of the above technical solution, the display panel includes a driving circuit layer; the driving circuit layer includes at least one conductive layer, and the at least one conductive layer includes a first connecting line.

[0039] Specifically, Figure 3 Schematic diagram of the cross-sectional structure of a display panel provided by an embodiment of the present invention. Figure 3 As shown, the display panel includes a driving circuit layer 140, and may further include a substrate 150 and a light emitting device layer ( Figure 3 (not shown in the figure), the driving circuit layer 140 is provided on the substrate 150, and is used to form a first pixel and a signal line. The driving circuit layer 140 can also be used to form a first virtual pixel, and the first virtual pixel is used to set the first connection line. Therefore, the first virtual pixel can only include at least part of the film layer in the driving circuit layer 140. The light-emitting device layer is provided on the side of the driving circuit layer 140 away from the substrate 150, and is used to form a first light-emitting unit. The driving circuit layer 140 includes at least one conductive layer, which is used to form a transistor T1, a capacitor C1 and a signal line. The first pixel is formed by interconnecting multiple transistors T1 and capacitors C1. Figure 3The example in the figure shows that the driving circuit layer 140 includes three metal layers: a first metal layer M1 forming the gate of transistor T1, the first plate of capacitor C1, and the scan line and light control signal line; a second metal layer M2 forming the second plate of capacitor C1; and a third metal layer M3 forming the source, drain, and data line of transistor T1. At the corresponding position of the first virtual pixel on the substrate, at least one of the three metal layers is used to form the first connecting line. This avoids the need for an additional conductive layer for forming the first connecting line. Furthermore, the first connecting line can be formed simultaneously with the process of forming the first pixel and signal line, reducing the number of masks required for the display panel, saving the cost of the display panel, and simplifying the display panel process.

[0040] It should be noted that the driving circuit layer 140 can be used to form the first pixel and the first virtual pixel at the same time. Before the conductive layer is used to form the first connecting line at the corresponding position of the first virtual pixel, the driving circuit layer 140 may include other film layers. In this case, the other film layers can be synchronously formed with the same structure at the positions corresponding to the first pixel and the first virtual pixel, which is beneficial to simplify the process flow of the display panel. For example, when the first metal layer M1 is used to form the first connecting line, before the first connecting line is formed, the buffer layer and the semiconductor layer of the transistor T1 can be synchronously formed at the positions corresponding to the first pixel and the first virtual pixel. In this case, the first pixel and the first virtual pixel have the same structure. When the second metal layer M2 is used to form the first connecting line, before the first connecting line is formed, the buffer layer, the semiconductor layer of the transistor T1, the first metal layer M1 and the gate insulating layer can be synchronously formed at the positions corresponding to the first pixel and the first virtual pixel. In this case, the first pixel and the first virtual pixel also have the same structure. When the third metal layer M3 is used to form the first connecting line, before the first connecting line is formed, a buffer layer, a semiconductor layer of the transistor T1, a first metal layer M1, a gate insulating layer, a second metal layer M2 and an interlayer insulating layer can be synchronously formed at positions corresponding to the first pixel and the first virtual pixel. At this time, the first pixel and the first virtual pixel also have the same structure.

[0041] Based on the above technical solution, the first connecting line and the corresponding connected signal line are arranged on the same layer.

[0042] Specifically, the signal line may include at least one of a data line, a scan line, and a light-emission control signal line. When the signal line includes a scan line and / or a light-emission control signal line, the first connecting line may be disposed on the first metal layer. In this case, the first connecting line and the signal line are disposed on the same layer, and the signal line and the first connecting line can be formed in the same process, thereby simplifying the display panel manufacturing process. Furthermore, the signal line and the first connecting line can be formed as one, allowing them to be directly connected. When the signal line extends to the non-display area via the first connecting line, the connection process between the first connecting line and the signal line is simplified, further simplifying the display panel manufacturing process. Similarly, when the signal line includes a data line, the first connecting line may be disposed on the third metal layer, allowing them to be disposed on the same layer, and the signal line and the first connecting line can also be formed in the same process, thereby simplifying the display panel manufacturing process. Furthermore, the signal line and the first connecting line may be formed as one, allowing them to be directly connected. When the signal line extends to the non-display area via the first connecting line, the connection process between the first connecting line and the signal line is simplified, further simplifying the display panel manufacturing process. Alternatively, the signal line can include a scan line, a light-emitting control signal line and a data line at the same time. In this case, there are multiple first connecting lines, and the first connecting lines connected to the scan line and the light-emitting control signal line are set in the first metal layer, and the first connecting lines connected to the data line are set in the third metal layer, which can also simplify the process flow of the display panel.

[0043] Figure 4 FIG1 is a schematic diagram of another display panel structure provided by an embodiment of the present invention. Figure 4 As shown, the second display area 120 is provided with a second light-emitting unit 123, and the second pixel unit 121 also includes a second pixel P2, the second pixel P2 is connected to the second light-emitting unit 123, and the second light-emitting unit 123 and the first light-emitting unit 111 are arranged in an array; the signal line 122 includes a control signal line 1221; in the same row of light-emitting units, the second pixel P2 corresponding to the second light-emitting unit 123 is connected to the same control signal line 1221, and the first pixel P1 in the first pixel unit 131 corresponding to the first light-emitting unit 111 is connected to the same control signal line 1221 through the first connection line L1.

[0044] Specifically, the second light-emitting unit 123 can be arranged corresponding to the second pixel unit 121. If a second pixel P2 is also arranged in the second pixel unit 121, then at least one second pixel unit 121 includes a first pixel P1 and a second pixel P2, and at least one second pixel unit 121 includes a first virtual pixel P0 and a second pixel P2. The second pixel P2 is connected to the second light-emitting unit 123, so that the second pixel P2 in each second pixel unit 121 can be connected to the corresponding second light-emitting unit 123, driving the second light-emitting unit 123 to emit light, thereby realizing display in the second display area 120. In addition, different second pixel units 121 are respectively provided with the first pixel P1 and the first virtual pixel P0, which helps to improve the consistency of the aperture ratios of different second pixel units 121, and further helps to improve the display consistency of the display panel. When the second light-emitting units 123 and the first light-emitting units 111 are arranged in an array, the first light-emitting units 111 in the first display area 110 and the second light-emitting units 123 in the second display area 120 can be arranged in an array as a whole.

[0045] It should be noted that when the second light-emitting unit 123 includes light-emitting devices of multiple colors, each second pixel unit 121 may include multiple second pixels P2, with each second pixel P2 being connected to a corresponding light-emitting device. For example, if the second light-emitting unit 123 includes a red light-emitting device, a green light-emitting device, and a blue light-emitting device, the second pixel unit 121 may include three second pixels P2, each second pixel P2 being connected to a light-emitting device of a corresponding color, so that each light-emitting device can be independently driven.

[0046] The control signal line 1221 may include at least one of a scan line and a light emitting control signal line. The light emitting unit includes a first light emitting unit 111 and a second light emitting unit 123. In this case, the first light emitting unit 111 and at least part of the second light emitting unit 123 are arranged in the same row and / or in the same column. Figure 4 As shown, the control signal line 1221 extends along the row direction X of the light-emitting unit. There are multiple control signal lines 1221, each of which is arranged corresponding to a row of light-emitting units, and is used to connect to the pixels corresponding to a row of light-emitting units, and provide at least one of a scanning signal and a light-emitting control signal to the pixels corresponding to a row of light-emitting units, so that a row of pixels can drive a row of light-emitting units to emit light. When the second display area 120 is arranged at least partially around the first display area 110, at least one row of light-emitting units includes a first light-emitting unit 111 and a second light-emitting unit 123. The first pixel P1 corresponding to at least one first light-emitting unit 111 is arranged in the non-display area 130. At this time, the first pixel P1 arranged in the non-display area 130 is connected to the control signal line 1221 corresponding to the same row of light-emitting units through the first connection line L1, which can ensure that the driving mode of the light-emitting units in the same row remains unchanged.

[0047] For example, Figure 4 As shown, multiple rows and columns of first light-emitting units 111 are provided in the first display area 110, such that the multiple rows of light-emitting units include the first light-emitting units 111 and the second light-emitting units 123. In the first row of the multiple rows of light-emitting units, the second pixel P2 corresponding to the second light-emitting unit 123 is arranged in the same row as the second light-emitting unit 123, the first pixels P1 corresponding to the first light-emitting units 111 in some columns (for example, the fifth, sixth, and seventh columns in the first display area 110) are arranged in the non-display area 130, and the first pixels P1 corresponding to the first light-emitting units 111 in some columns (for example, the first to fourth columns in the first display area 110) are arranged in the same row as the second light-emitting unit 123. When the control signal line 1221 corresponding to the first row of light-emitting units in multiple rows of light-emitting units provides a scanning signal and / or a light-emitting control signal to the pixels corresponding to the row of light-emitting units, the control signal line 1221 is directly connected to the second pixel P2 and the first pixel P1 corresponding to the first light-emitting unit 111 in the first column, and then connected to the first pixel P1 corresponding to the first light-emitting unit 111 in some columns (for example, the fifth column, the sixth column and the seventh column in the first display area 110) through the first connection line L1, so that one control signal line 1221 can provide a scanning signal and / or a light-emitting control signal to the pixels corresponding to a row of light-emitting units, thereby ensuring that the driving mode of the light-emitting units in the same row remains unchanged.

[0048] Among them, the non-display area 130 can be provided with multiple rows of first pixel units 131, and a row of first pixel units 131 in the non-display area 130 can be connected to the same control signal line 1221. In this case, the first light-emitting units 111 corresponding to a row of first pixel units 131 are arranged in the same row. In other embodiments, a row of first pixel units 131 in the non-display area 130 can also be connected to different control signal lines 1221. In this case, the first light-emitting units 111 corresponding to a row of first pixel units 131 are arranged in different rows. For example, Figure 5 FIG1 is a schematic diagram of another display panel structure provided by an embodiment of the present invention. Figure 5 As shown, the control signal line 1221 corresponding to the first row of light-emitting units corresponding to the first display area 110 and the control signal line 1221 corresponding to the second row of light-emitting units are both connected to the first pixel units 131 in the same row through different first connection lines L1. At this time, the first pixel P1 connected to the control signal line 1221 corresponding to the first row of light-emitting units corresponding to the first display area 110 is connected to the first light-emitting unit 111 in the first row in the first display area 110, and the first pixel P1 connected to the control signal line 1221 corresponding to the second row of light-emitting units corresponding to the first display area 110 is connected to the first light-emitting unit 111 in the second row in the first display area 110, so as to realize that the pixels corresponding to the light-emitting units in the same row are provided with scanning signals or light-emitting control signals through the same control signal line 1221.

[0049] It should be noted that, in other embodiments, the same control signal line 1221 can also be connected to the first pixel units 131 in different rows. In this case, the first light-emitting units 111 corresponding to the first pixel units 131 in different rows are arranged in the same row. It is only necessary to ensure that the pixels corresponding to the light-emitting units in the same row are provided with scanning signals or light-emitting control signals through the same control signal line 1221. No limitation is made here.

[0050] In other embodiments, the signal line may also be a data line. Figure 6 FIG1 is a schematic diagram of another display panel structure provided by an embodiment of the present invention. Figure 6 As shown, the second display area 120 is provided with a second light-emitting unit 123, and the second pixel unit 121 also includes a second pixel P2, the second pixel P2 is connected to the second light-emitting unit 123, and the second light-emitting unit 123 and the first light-emitting unit 111 are arranged in an array; the signal line 122 includes a data line 1222, and in the same column of light-emitting units, the second pixel P2 corresponding to the second light-emitting unit 123 is connected to the same data line 1222, and the first pixel P1 in the first pixel unit 131 corresponding to the first light-emitting unit 111 is connected to the same data line 1222 through the first connection line L1.

[0051] Specifically, the signal line 122 can also be a data line 1222, and the data line 1222 extends along the column direction Y of the light-emitting unit. There can be multiple data lines 1222, each of which is arranged corresponding to a column of light-emitting units, and is used to connect to the pixels corresponding to a column of light-emitting units, and provide data signals to the pixels corresponding to a column of light-emitting units, so that a column of pixels can drive a column of light-emitting units to emit light. When the second display area 120 is arranged at least partially around the first display area 110, at least one column of light-emitting units includes a first light-emitting unit 111 and a second light-emitting unit 123 at the same time. The first pixel P1 corresponding to at least one first light-emitting unit 111 is arranged in the non-display area 130. At this time, the first pixel P1 arranged in the non-display area 130 is connected to the data line 1222 corresponding to the same column of light-emitting units through the first connection line L1, which can ensure that the driving mode of the light-emitting units in the same column remains unchanged.

[0052] For example, Figure 6As shown, multiple rows and columns of first light-emitting units 111 are disposed in the first display area 110, such that the multiple columns of light-emitting units include first light-emitting units 111 and second light-emitting units 123. In some columns of the multiple columns of light-emitting units (e.g., the first to fourth columns in the first display area 110), the first pixels P1 corresponding to the first light-emitting units 111 are disposed in the second display area 120 and are disposed in a different column from the corresponding columns of light-emitting units, for example, on one side of the first display area 110 along the row direction X. In some columns of the multiple columns of light-emitting units (e.g., the fifth, sixth, and seventh columns in the first display area 110), the second pixels P2 corresponding to the second light-emitting units 123 are disposed in a different column from the second light-emitting units 123. In some columns of the multiple columns of light-emitting units (e.g., the fifth, sixth, and seventh columns in the first display area 110), the first pixels P1 corresponding to the first light-emitting units 111 are disposed in the non-display area 130 and are disposed in a different column from the corresponding second light-emitting units 123. The second display area 120 is at least partially disposed around the first display area 110, allowing the data lines 1222 corresponding to some columns of the multiple columns of light-emitting units to be disposed around the first display area 110. This allows a single data line 1222 to provide data signals to pixels corresponding to some columns of the multiple columns of light-emitting units (e.g., the first to fourth columns within the first display area 110), thereby ensuring that the driving mode of the light-emitting units in the same column remains unchanged. The first display area 110 may also divide the data lines 1222 corresponding to some columns of the multiple columns of light-emitting units (e.g., the fifth, sixth, and seventh columns within the first display area 110) into two portions along the column direction Y. The first portion is used to connect to the second pixel P2 on one side of the first display area 110 along the column direction Y, and the second portion is used to connect to the second pixel P2 on the other side of the first display area 110 along the column direction Y and / or the first pixel P1 in the non-display area 130 via the first connection line L1. This allows a single data line 1222 to provide data signals to pixels corresponding to a single column of light-emitting units, thereby ensuring that the driving mode of the light-emitting units in the same column remains unchanged. When the data line 1222 is connected to the second pixel P2 on the other side of the first display area 110 along the column direction Y and the first pixel P1 in the non-display area 130 through the first connecting line L1, the data line 1222 can be avoided from being wound on both sides of the first display area 110 along the row direction X, which is beneficial to improving the wiring and display effects of the display panel.

[0053] Figure 7 FIG1 is a schematic diagram of another display panel structure provided by an embodiment of the present invention. Figure 7As shown, the signal line can include a control signal line 1221 and a data line 1222 at the same time. When a row of light-emitting units includes the first light-emitting unit 111 and the second light-emitting unit 123 at the same time, and a column of light-emitting units includes the first light-emitting unit 111 and the second light-emitting unit 123 at the same time, and the data line 1222 corresponding to the light-emitting unit in the first display area 110 is divided into two parts, the control signal line 1221 can be connected to the first pixel P1 in the non-display area 130 through a first connection line L1, and the data line 1222 can be connected to the first pixel P1 in the non-display area 130 through a first connection line L1, to ensure that the row and column driving mode of the light-emitting unit remains unchanged.

[0054] It should be noted that when different first connection lines L1 are respectively connected to a control signal line 1221 and a data line 1222, the different first connection lines L1 can be set within a first virtual pixel P0, which helps reduce the number of first virtual pixel P0 settings, thereby improving the consistency of the display panel during the manufacturing process and simplifying the manufacturing process of the display panel. In addition, when the first connection lines L1 corresponding to the control signal line 1221 and the data line 1222 are set within the same first virtual pixel P0, the first connection lines L1 corresponding to the control signal line 1221 and the data line 1222 can be set on different layers to avoid short circuiting of the first connection lines L1 corresponding to the control signal line 1221 and the data line 1222. For example, the first connection line L1 corresponding to the control signal line 1221 is set on the same layer as the control signal line 1221, and the first connection line L1 corresponding to the data line 1222 is set on the same layer as the data line 1221.

[0055] Figure 8 FIG1 is a schematic diagram of another display panel structure provided by an embodiment of the present invention. Figure 8 As shown, the display panel also includes a first transparent conductive line L11 and a second transparent conductive line L12. The first transparent conductive line L11 extends along the row direction X of the light-emitting unit, and the first pixel P1 in the second pixel unit 121 is connected to the first light-emitting unit 111 through the first transparent conductive line L11; the second transparent conductive line L12 extends along the column direction Y of the light-emitting unit, and the first pixel P1 in the first pixel unit 131 is connected to the first light-emitting unit 111 through the second transparent conductive line L12.

[0056] Specifically, the first transparent conductive line L11 and the second transparent conductive line L12 can be the anode lead of the first light-emitting unit 111. When the second display area 120 at least partially surrounds the first display area 110, the first pixel P1 in at least one second pixel unit 121 is arranged in the same row as the first light-emitting unit 111. At this time, the first pixel P1 in the second pixel unit 121 and the first light-emitting unit 111 in the same row can be connected through the first transparent conductive line L11, which is beneficial to reducing the length of the first transparent conductive line L11. At the same time, the first pixel P1 in at least one first pixel unit 131 is arranged in the same column as the first light-emitting unit 111. At this time, the first pixel P1 in the first pixel unit 131 and the first light-emitting unit 111 in the same column can be connected through the second transparent conductive line L12. When the first light-emitting unit 111 is simultaneously in the same row as the first pixel P1 in the second pixel unit 121 and in the same column as the first pixel P1 in the first pixel unit 131, the connection relationship can be determined according to the length of the first transparent conductive line L11 and the length of the second transparent conductive line L12. For example, Figure 8 It is exemplarily shown in the figure that the first display area includes multiple rows and columns of first light-emitting units 111, and the distance between the first light-emitting units 111 in some rows and columns (for example, the first to fourth columns of all rows in the first display area 110) and the first pixel P1 in the second pixel unit 121 on one side of the first display area 110 along the row direction X is smaller than the distance between the first light-emitting unit 111 in the first column and the first pixel P1 in the first pixel unit 131. At this time, the first light-emitting units 111 in some rows and columns (for example, the first to fourth columns of all rows in the first display area 110) can be connected to the first pixel P1 in the second pixel unit 121 through the first transparent conductive line L11. Similarly, the distance between the first light-emitting units 111 in some rows and columns (e.g., the fifth, sixth, and seventh columns of the first row in the first display area 110) and the first pixel P1 in the first pixel unit 131 is shorter than the distance between the first light-emitting units 111 in some rows and columns (e.g., the fifth, sixth, and seventh columns of the first row in the first display area 110) and the first pixel P1 in the second pixel unit 121 on one side of the first display area 1110 along the row direction X. In this case, the first light-emitting units 111 in some rows and columns (e.g., the fifth, sixth, and seventh columns of the first row in the first display area 110) can be connected to the first pixel P1 in the first pixel unit 131 via the second transparent conductive line L12. Furthermore, the connection relationship between other first light-emitting units 111 and the first pixel P1 can also be determined based on the distance to the first pixel P1 in the second pixel unit 121 on the one side of the first display area 1110 along the row direction X and the distance to the first pixel P1 in the first pixel unit 131.

[0057] Continue to refer Figure 8In the first direction X, the first pixel P1 in at least one second pixel unit 121 is arranged on a side of the first virtual pixel P0 close to the first display area 110; wherein the first direction X is the row direction in which the first light-emitting units 111 are arranged.

[0058] Specifically, the first pixel P1 is connected to the first light emitting unit 111 and is used to drive the first light emitting unit 111 to emit light. When the second pixel unit 121 includes the first pixel P1, by setting the first pixel P1 in at least one second pixel unit 121 to be located on the side of the first virtual pixel P0 close to the first display area 110, the first pixel P1 in the second pixel unit 121 can be set adjacent to the first display area 110, thereby reducing the length of the line connecting the first pixel P1 in the second pixel unit 121 to the first light emitting unit 111. Figure 8 It can be seen that the first pixels P1 in the second pixel unit 121 connected to the first light emitting unit 111 can all be located on a side of the first virtual pixel P0 close to the first display area 110 .

[0059] It should be noted that the number of first light-emitting units 111 is less than the number of second pixel units 121. This allows the second display area 120 to have multiple second pixel units 121 with vacant first pixels P1. In this case, the second pixel units 121 with vacant first pixels P1 can be arranged in an array within the second display area 120 to provide drive signals for the second light-emitting units 123 within the second display area 120. By providing vacant first pixels P1 within other second pixel units 121, the consistency of the aperture ratios of all second pixel units 121 within the second display area 120 is improved, which helps to improve the consistency of the pixel density within the second display area 120, thereby improving the display consistency of the display panel.

[0060] Figure 9 FIG1 is a schematic diagram of another display panel structure provided by an embodiment of the present invention. Figure 9 As shown, the first pixel unit 131 further includes a second virtual pixel P3, and the occupied area of ​​the second virtual pixel P3 is equal to the occupied area of ​​the first virtual pixel P0.

[0061] Specifically, the second pixel unit 121 can be provided with the second pixel P2, and can also be provided with the first pixel P1 or the first dummy pixel P0. The first pixel unit 131 is provided with the first pixel P1. When the first display area 110 and the second display area 120 are displayed as a whole, the first light emitting unit 111 and the second light emitting unit 123 have light emitting devices of the same light emitting color, so that the first pixel P1 in the first pixel unit 131 has the same number as the second pixel P2 in the second pixel unit 121. For example, the first light emitting unit 111 and the second light emitting unit 123 each have red light emitting devices, green light emitting devices and blue light emitting devices, so that the number of the first pixel P1 in the first pixel unit 131 is equal to the number of the second pixel P2 in the second pixel unit 121, both of which are three. At this time, the second dummy pixel P3 is arranged in the first pixel unit 131, and the occupied area of the second dummy pixel P3 is equal to the occupied area of the first dummy pixel P0, which can make the occupied area of the first pixel unit 131 similar to the occupied area of the second pixel unit 121, thereby facilitating the consistency of the aperture ratio of the first pixel unit 131 and the second pixel unit 121, facilitating the consistency of the pixel density in the first display area 110 and the second display area 120, and further improving the display consistency of the display panel.

[0062] On the basis of the above technical solution, the second dummy pixel is arranged in the same layer as the first pixel.

[0063] Specifically, the first pixel can be formed by a driving circuit layer. When the first pixel is formed, the second dummy pixel can be formed synchronously by the driving circuit layer, so that the second dummy pixel is arranged in the same layer as the first pixel, thereby the second dummy pixel and the first pixel can be formed simultaneously in the same process, and the process flow of the display panel is simplified.
