[0039] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] In the embodiments of the present application, words such as "first", "second", "third", and "fourth" are used to distinguish between identical or similar items with basically the same functions and effects. This is only for the purpose of clearly describing the technical solutions of the embodiments of the present application, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0041] In the embodiments of the present application, “a plurality of” means two or more, and “at least one” means one or more, unless otherwise clearly defined.

[0042] In the embodiments of the present application, the terms "upper" and "lower" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0043] like Figures 1 to 8As shown, the embodiment of the present application provides a display device. The display device can be a mobile phone, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), a wearable device, a virtual reality device, or a mobile computing device, and other devices having a display panel 100. The embodiment of the present application is not limited to this. For ease of description, the present application takes a smart watch as an example for explanation.

[0044] Figure 1 This is a schematic diagram of a display device provided in an embodiment of the present application. Figure 1 As shown, the display device may include a body 1 and a strap 2. The body 1 serves as the main structure of the display device and is used to implement the main functions of the display device (e.g., calls, exercise monitoring, health monitoring, etc.). The strap 2 is connected to the body 1 and is used to detachably wear the body 1 on the user's wrist. For example, Figure 1 As shown, the display device includes two straps 2, one of which is connected to the upper side of the body 1, and the other is connected to the lower side of the body 1. When worn, the two straps 2 are wrapped around the user's wrist and connected by a buckle structure (not shown in the figure). It is understood that in actual application, the body can also be worn on the user's wrist in other ways, and this embodiment of the application is not limited to this.

[0045] The main body includes a housing and a display panel 100 connected to the housing.

[0046] The housing serves as the skeleton of the body and is used to support and connect various components of the display device.

[0047] For example, the housing has a recess for housing components of the display device, such as the CPU, motherboard, memory, battery, sensor, and communication components. The display panel 100 covers the opening of the recess to seal the recess and protect the components housed therein.

[0048] For example, when the housing is provided with a groove, a watch strap is connected to the outer wall of the groove. The watch strap and the housing may be an integral structure, and the watch strap may also be detachably connected to the outer wall of the groove to facilitate maintenance and replacement of the watch strap.

[0049] Figure 2 This is a schematic diagram of a main body of a display device provided in an embodiment of the present application. Figure 3 This is a schematic diagram of a main body of another display device provided in an embodiment of the present application. Figure 4 This is a schematic diagram of another display device provided in an embodiment of the present application. Figure 2 、 Figure 3 and Figure 4As shown, the shape of the shell can be a rectangular parallelepiped, a cylinder, etc. Of course, the shape of the shell can also be a polygonal column, an elliptical column, a frustum, a pyramid, etc. The embodiment of the present application does not limit the shape of the shell.

[0050] The material of the shell can be metal or plastic, and can be flexibly selected according to needs during actual application.

[0051] The display panel 100 may be an electroluminescent display panel or a photoluminescent display panel. In the case where the display panel 100 is an electroluminescent display panel, the electroluminescent display panel may be an organic light-emitting diode (OLED) display panel, a quantum dot light-emitting diode (QLED) display panel, or an active-matrix organic light-emitting diode (AMOLED) display panel. Organic light-emitting diode display panels have been widely used in the display field due to their advantages such as self-luminescence, low driving voltage, high luminous efficiency, fast response speed, and flexible display. Therefore, in the embodiments of the present application, only the display panel 100 is described as an OLED display panel.

[0052] The display panel 100 can display images and present information to the user through displayed images. For example, the display panel 100 can present the user with the display device's call status, motion monitoring data, health monitoring data, and so on. The images displayed by the display panel 100 can be either static or dynamic, and the image content can be text, images, or both.

[0053] To increase the flexibility of the display panel 100 in displaying information, the display panel 100 may include a main screen 110 and a secondary screen 120. During operation of the display device, the main screen 110 and the secondary screen 120 may be controlled independently. For example, when the display panel 100 displays an image, the main screen 110 and the secondary screen 120 may display the image simultaneously, or either the main screen 110 or the secondary screen 120 may display the image. When the main screen 110 and the secondary screen 120 display an image simultaneously, the main screen 110 and the secondary screen 120 may display the same image or different images.

[0054] For example, Figure 2 As shown, the main body is a rectangular parallelepiped structure as a whole, the main screen 110 can be set on the top surface of the main body, and the sub-screen 120 can be set on the side of the main body.

[0055] For example, Figure 3 As shown, the main body is a cylindrical structure as a whole, the main screen 110 can be set on the top surface of the main body, and the sub-screen 120 can be set on the side of the main body.

[0056] For example, Figure 4 As shown, the main body is a cylindrical structure as a whole. The main screen 110 can be set on the top surface of the main body, and the sub-screen 120 can be set between the top surface and the side surface of the main body, and the light-emitting surface of the sub-screen 120 is at a certain angle to the light-emitting surface of the main screen 110.

[0057] It should be noted that in the above three examples, the secondary screen 120 surrounds the main screen 110, and the periphery of the main screen 110 is correspondingly provided with a secondary screen 120. In actual application, the secondary screen 120 can also partially surround the main screen 110. For example, in Figure 2 In the example shown, the secondary screen 120 may cover only one side surface, two side surfaces, or three side surfaces of the four side surfaces of the main body.

[0058] The names of the main screen 110 and the secondary screen 120 are merely used to distinguish the two display screens. There is no structural or functional relationship between the main screen 110 and the secondary screen 120, and the names of the two can be interchanged. For example, in some examples, the main screen 110 can also be called the secondary screen 120, and the secondary screen 120 can also be called the main screen 110.

[0059] When the main screen 110 and the secondary screen 120 display different images, for example, the main screen 110 can be used to display call status, exercise monitoring data, health monitoring data, etc., and the secondary screen 120 can be used to display Bluetooth connection status, remaining battery power, etc. This can increase the flexibility of the display device in displaying information.

[0060] The area of ​​the main screen 110 may be larger or smaller than the area of ​​the secondary screen 120, or the area of ​​the main screen 110 may be equal to the area of ​​the secondary screen 120. The embodiment of the present application does not limit the relative sizes of the main screen 110 and the secondary screen 120.

[0061] The main screen 110 and the secondary screen 120 are not two independent display screens, but belong to the same display panel 100 and are connected into an integrated structure via the connection area 130. That is, the display panel 100 is divided into three areas: the main screen 110, the secondary screen 120, and the connection area 130 located between the main screen 110 and the secondary screen 120.

[0062] Figure 5 A schematic diagram of a display panel provided in an embodiment of the present application. Figure 6 A schematic diagram of another display panel provided in an embodiment of the present application. Figure 5 and Figure 6Secondary screen 120 is a strip-shaped screen. This refers to a strip-shaped secondary screen 120 that is elongated, with its length significantly greater than its width. The strip-shaped screen includes a first edge 121 extending along its length. After secondary screen 120 is bent, first edge 121 at least partially surrounds the perimeter of primary screen 110.

[0063] For example, Figure 5 As shown, the display panel 100 includes a main screen 110 that is generally rectangular, a secondary screen 120 that is generally strip-shaped, and a connection area 130 that connects the main screen 110 and the secondary screen 120. During the preparation of the display device, the display panel 100 is bent along the common edge of the main screen 110 and the secondary screen 120 in the connection area 130, so that the light-emitting surface of the main screen 110 and the light-emitting surface of the secondary screen 120 form an angle of 270 degrees. Then, the secondary screen 120 is further bent along the periphery of the main screen 110, so that the first edge 121 surrounds the periphery of the main screen 110, and the two ends of the secondary screen 120 are connected to form a folded portion as shown in FIG. Figure 2 The structure of the display panel 100 is shown in the example shown.

[0064] For example, Figure 6 As shown, the display panel 100 includes a main screen 110 that is generally circular, a sub-screen 120 that is generally arc-shaped, and a connection area 130 connecting the main screen 110 and the sub-screen 120. During the preparation of the display device, the display panel 100 is bent along the common edge of the main screen 110 and the sub-screen 120 in the connection area 130, so that the light-emitting surface of the main screen 110 and the light-emitting surface of the sub-screen 120 form an angle of 225 degrees. Then, the sub-screen 120 is further bent along the periphery of the main screen 110, so that the first edge 121 surrounds the periphery of the main screen 110, so that the two ends of the sub-screen 120 are connected, so that the sub-screen 120 surrounds the main screen 110, forming a circle as shown in FIG. Figure 4 The structure of the display panel 100 in the example shown. Of course, the angle between the light emitting surface of the main screen 110 and the light emitting surface of the auxiliary screen 120 can also be other angles. For example, when the angle is 270 degrees, the following is formed: Figure 3 Display panel 100 in the example shown.

[0065] Figure 5 and Figure 6 In the example shown, the shape of the main screen 110 is different from the shape of the sub-screen 120. In actual application, the shape of the main screen 110 and the shape of the sub-screen 120 may also be the same.

[0066] The connection area 130 connects the main screen 110 and the secondary screen 120. The embodiment of the present application does not limit the shape and size of the connection area 130. For example, Figure 5 As shown, the connection area 130 can be the common edge of the main screen 110 and the secondary screen 120. Figure 6 As shown, the connection area 130 may be an area around the tangent point between the main screen 110 and the sub-screen 120 .

[0067] Since the main screen 110 and the auxiliary screen 120 are bent through the connection area 130, the smaller the connection area 130 is, the more conducive it is to the relative bending between the main screen 110 and the auxiliary screen 120. In particular, the shape of the display panel 100 is Figure 6 When the shape shown in FIG. 1 is a circular main screen 110 and the sub-screen 120 is an arc-shaped sub-screen 120, when the connection area 130 is too large, the connection area 130 is along the Figure 6 The horizontal dimension is relatively large, which causes wrinkles to easily form when the main screen 110 and the auxiliary screen 120 are bent relative to each other.

[0068] Of course, the main screen 110 and the sub-screen 120 of the display panel 100 may also be located on the same plane, in which case the connecting area 130 is not bent.

[0069] The display panel 100 may be connected to a driver chip 150 for driving the display panel 100. The driver chip 150 may provide data signals for driving the main screen 110 to display images, as well as data signals for driving the secondary screen 120 to display images. The driver chip 150 may be connected to either the main screen 110 or the secondary screen 120. For ease of description, the following description will only take the example of the driver chip 150 being connected to the main screen 110.

[0070] For example, continue to refer to Figure 6 The main screen 110 is provided with a driving region 140, and the driving chip 150 is connected to the driving region 140. In the display device, the driving region 140 and the driving chip 150 are bent along the common edge of the driving region 140 and the main screen 110, so that the driving region 140 and the driving chip 150 are located on the back of the main screen 110.

[0071] The main screen 110 includes a main display area 111. The main display area 111 includes a plurality of pixels arranged in an array. The plurality of pixels cooperate with each other to display an image. A pixel is a light-emitting unit, including a light-emitting device and a driving circuit for driving the light-emitting device.

[0072] The pixels arranged in an array in the main display area 111 form multiple pixel columns, each including multiple pixels. A plurality of first data lines are provided in the main display area 111. Each first data line is connected to a driving circuit of a pixel column to provide a data signal to the pixel column.

[0073] For example, Figure 6 As shown, the main screen 110 includes a circular main display area 111 and an annular first non-display area 112 surrounding the main display area 111. The multiple pixels in the main display area 111 form multiple pixel columns extending along the vertical direction shown in the figure, and the first data line also extends along the vertical direction shown in the figure.

[0074] A first connecting line is provided in the main screen 110 , one end of the first connecting line is connected to the driving chip 150 , and the other end of the first connecting line is connected to the first data line to transmit the data signal sent by the driving chip 150 to the first data line through the first connecting line.

[0075] A plurality of first data lines are provided in the main display area 111 , and correspondingly, a plurality of first connection lines may also be provided, and the first connection lines correspond to the first data lines one by one.

[0076] The number of the first connection lines may also be smaller than the number of the first data lines to reduce the border of the main screen 110 .

[0077] For example, a data selection circuit (Multiplexer, MUX) is provided between the driver region 140 and the main display area 111 of the main screen 110 (e.g., the first non-display area 112). The first connection line is connected to the first data line via the MUX. For example, if the data selection circuit is a 1:6 MUX, the number of first connection lines is equal to 1 / 6 of the number of first data lines. Furthermore, the provision of the data selection circuit can reduce the power consumption of the display device and reduce the requirement for the number of data signal output paths of the driver chip 150, thereby expanding the range of options available to the driver chip 150.

[0078] When a data selection circuit is provided in the main screen 110 , the data selection circuit may be located in the lower semicircular area of ​​the first non-display area 112 as shown.

[0079] In addition, a gate driving circuit 124 (Gate On Array, GOA for short), VDD, VSS, Vinit and other signal lines may be disposed in the first non-display area 112 .

[0080] In some examples, a test circuit (Cell Test, CT) may be provided in the first non-display area 112 to test the performance of the main screen 110. If the test passes, the driver chip 150 is bound to the driver area 140. The test circuit may be located in the upper semicircular area of ​​the first non-display area 112.

[0081] The secondary display 120 includes a secondary display area. The secondary display area includes multiple pixels arranged in an array, which work together to display images. The pixels arranged in the array within the secondary display area form multiple pixel columns, each of which includes multiple pixels. Multiple second data lines 122 are provided within the secondary display area. Each second data line 122 is connected to the driver circuit of a pixel column to provide a data signal for that pixel column.

[0082] A second connection line 123 is provided in the display panel 100. One end of the second connection line 123 is connected to the driving chip 150, and the other end of the second connection line 123 passes through the connection area 130 and is connected to the second data line 122, so that the data signal emitted by the driving chip 150 is transmitted to the second data line 122 through the second connection line 123.

[0083] In the embodiment of the present application, the second connection line 123 for providing data signals to the pixels in the secondary screen 120 passes through the connection area 130 and enters the main screen 110, so that the first connection line providing data signals to the pixels in the main screen 110 can merge with the second connection line 123 and then connect to the driver chip 150. In other words, the main screen 110 and the secondary screen 120 can share the driver chip 150. Compared with providing separate driver chips 150 for the main screen 110 and the secondary screen 120, the number of driver chips 150 is reduced, and power consumption is also reduced.

[0084] Exemplarily, the display device includes a driver chip 150 that provides data signals to both the primary screen 110 and the secondary screen 120. For example, the output port located in the middle of the driver chip 150 is connected to the first connection line, and the output ports located on both sides of the driver chip 150 are connected to the second connection line 123.

[0085] When the secondary screen 120 is a strip-shaped screen, the multiple pixels included in a pixel column are arranged along the extension direction of the first side 121. The second data line 122 extends along the direction of the pixel column, and is configured so that one second data line 122 provides data signals to the pixels in a pixel column. The pixels in the pixel column are arranged along the extension direction of the first side 121, which means that the arrangement direction of the pixels is substantially the same as the extension direction of the first side 121. This includes both the arrangement direction of the pixels being parallel to the extension direction of the first side 121 and the arrangement direction of the pixels forming a certain angle with the extension direction of the first side 121.

[0086] Because the secondary screen 120 is a strip-shaped screen, the dimension of the secondary screen 120 along the direction extending from the first side 121 is much greater than the dimension perpendicular to the first side 121. This means that more pixels are arranged along the direction extending from the first side 121, while fewer pixels are arranged perpendicular to the first side 121. Pixel columns extend along the direction of the first side 121, resulting in a larger number of pixels within a pixel column and a smaller number of pixel columns. Consequently, fewer second data lines 122 are provided corresponding to the pixel columns.

[0087] On the one hand, the smaller number of second data lines 122 can result in a smaller number of second connection lines 123 connected to the second data lines 122. Furthermore, the smaller number of second connection lines 123 can reduce the size of the connection area 130, thereby facilitating relative bending of the main screen 110 and the auxiliary screen 120. When the second connection lines 123 are routed within the first non-display area 112 of the main screen 110, the smaller number of second connection lines 123 can reduce the area of ​​the first non-display area 112, thereby reducing the border of the main screen 110 and improving the screen-to-body ratio of the main screen 110.

[0088] On the other hand, a smaller number of second data lines 122 can result in a smaller number of second connection lines 123 connected to the second data lines 122, and a smaller number of second connection lines 123 can reduce the restrictions on the number of output paths of the driver chip 150, so that one driver chip 150 can be used to drive the main screen 110 and the sub-screen 120 at the same time, thereby reducing power consumption.

[0089] Figure 7 for Figure 6 1 is a partial enlarged view of I. For example, Figure 7 As shown in the figure, a circle represents a pixel, and the pixels in the dotted box are part of a pixel column C. Figure 7 It can be seen that when the pixels in the pixel column C are arranged along the extension direction of the first side 121 , the number of pixel columns is relatively small.

[0090] The multiple pixels in the secondary screen 120 can also form multiple pixel rows, and the multiple pixels in the pixel rows are arranged along the second direction. The second direction intersects with the extension direction of the first side 121. For example, the second direction is perpendicular to the extension direction of the first side 121. Figure 7 In the figure, along the direction perpendicular to the first side 121, every three pixels form a pixel row.

[0091] When the secondary screen 120 is bent to form a circular screen, the pixels in the pixel row may be arranged along the radial direction of the circular ring.

[0092] in, Figure 7 The figure shows a case where the secondary screen 120 includes three pixel columns. In actual applications, the number of pixel columns can be greater than three. For example, the resolution of the secondary screen 120 is 72*1260, that is, the secondary screen 120 includes 72 pixel columns and 1260 pixel rows.

[0093] In actual applications, when a pixel column contains a large number of pixels, the display brightness of different pixels in the same pixel column varies, resulting in uneven display brightness on the secondary screen 120. Furthermore, due to the driving capabilities of the driver chip 150, when the pixel column contains a large number of pixels, some driver chips 150 may not be able to drive normally.

[0094] Figure 8 for Figure 6 The enlarged view of the part II in the figure is as follows: Figure 8 As shown, the second data line 122 can be disconnected at the first position to form a first sub-data line 122a and a second sub-data line 122b, wherein part of the second connection line 123 is connected to the first sub-data line 122a, and part of the second connection line 123 is connected to the second sub-data line 122b.

[0095] The first sub-data line 122a is connected to a portion of the pixels in a pixel column, while the second sub-data line 122b is connected to the remaining pixels in the same pixel column. This ensures that the number of pixels connected to the first sub-data line 122a and the number of pixels connected to the second sub-data line 122b are both less than the number of pixels in a pixel column. The first sub-data line 122a is connected to an output port of the driver chip 150 via a second connection line 123, and the second sub-data line 122b is connected to another output port of the driver chip 150 via another second connection line 123. This improves the uneven display of the secondary screen 120 and enables the driver chip 150 to properly drive the pixels connected to the first sub-data line 122a and the second sub-data line 122b.

[0096] That is, the secondary display area of ​​the secondary screen includes a first area and a second area, and the first area and the second area are driven separately. Figure 9 As shown, the resolution of the main display area 111 is 384*384, the resolution of the secondary screen is 24*1260, the resolution of the first area 120a of the secondary screen is 24*630, and the resolution of the second area 120b is 24*630. The driving chip drives the main display area 111, the first area 120a and the second area 120b at the same time.

[0097] Each second data line 122 can be disconnected at a certain position to form a first sub-data line 122a and a second sub-data line 122b. The disconnected positions of different second data lines 122 can be the same or different.

[0098] Furthermore, the first position can be the center position of the second data line 122, and is disconnected from the center position of the second data line 122, so that the lengths of the first sub-data line 122a and the second sub-data line 122b are equal, so that the number of pixels connected to the first sub-data line 122a is roughly equal to the number of pixels connected to the second sub-data line 122b, so that the display uniformity of the secondary screen 120 is better.

[0099] Of course, the first position may also be a non-center position of the second data line 122 , as long as the driving chip 150 can normally drive the pixels connected to the first sub-data line 122 a and the second sub-data line 122 b .

[0100] Continue to refer Figure 8 The second data line 122 forms a first end located at the first sub-data line 122a and a second end located at the second sub-data line 122b at the break; the first position is arranged adjacent to the connection area 130, wherein part of the second connection line 123 is connected to the first end, and wherein part of the second connection line 123 is connected to the second end.

[0101] Since the second connecting line 123 passes through the connecting area 130 and enters the sub-screen 120, and is then connected to the second data line 122 in the sub-screen 120, the disconnection position is set close to the connecting area 130, which makes it more convenient to connect the second connecting line 123 and the first sub-data line 122a and the second sub-data line 122b.

[0102] In actual use, the secondary screen 120 also includes a second non-display area surrounding the secondary display area. The second connecting line 123 can also enter the secondary screen 120 from the connecting area 130, run within the second non-display area, and then connect to the first sub-data line 122a and the second sub-data line 122b at appropriate locations. For example, the first sub-data line 122a and the second sub-data line 122b are connected at both ends of the secondary screen 120.

[0103] The secondary screen 120 includes a substrate, a driving circuit, and a light-emitting device stacked sequentially on the substrate. The driving circuit includes a first conductive layer and a second conductive layer arranged in different layers. The second data line 122 is located in the first conductive layer, and part of the second connecting line 123 is located in the second conductive layer. The second connecting line 123 and the second data line 122 are connected by a via. This makes the connection between the second connecting line 123 and the second data line 122 more convenient.

[0104] For example, the display panel 100 includes a substrate, and a driving circuit layer and a light-emitting device layer sequentially stacked on the substrate. The driving circuit may have a dual SD layer structure, including a first SD layer and a second SD layer (first conductive layer). The second data line 122 is located in the second SD layer. The display panel 100 may further include a third SD layer (second conductive layer), located on a side of the second SD layer facing away from the first SD layer. The second connection line 123 is located in the third SD layer.

[0105] Since the main screen 110 and the sub-screen 120 are both part of the display panel 100, the film structure of the main screen 110 and the sub-screen 120 can be the same. That is, the main screen 110 also includes a substrate and a drive circuit and light-emitting devices sequentially stacked on the substrate. The substrates of the main screen 110 and the sub-screen 120 are an integrated structure. The drive circuit layer of the main screen 110 and the drive circuit layer of the sub-screen 120 are arranged on the same layer, and the light-emitting device layer of the main screen 110 and the light-emitting device layer of the sub-screen 120 are arranged on the same layer.

[0106] The driving circuit includes a third conductive layer, and a portion of the second connecting line 123 is located in the third conductive layer. The third conductive layer of the main screen 110 and the second conductive layer of the auxiliary screen 120 can be a coextensive layer. That is, the driving circuit within the main screen 110 also has a dual-SD layer structure, including a first SD layer and a second SD layer, with the first data line located in the second SD layer. The display panel 100 may also include a third SD layer (third conductive layer), located on the side of the second SD layer facing away from the first SD layer, with the second connecting line 123 located in the third SD layer.

[0107] This allows the second connection line 123 to pass through the main display area 111 of the main screen 110 and into the connection area 130, shortening the routing of the second connection line 123 and reducing losses. Furthermore, since the line does not need to be routed within the first non-display area 112, the screen-to-body ratio of the main screen 110 is increased.

[0108] Of course, part of the second connection line 123 may also be located in the first non-display area 112. This can make the wiring in the main display area 111 simpler.

[0109] A data selection circuit (MUX) may be provided within the connection area 130, and the second connection line 123 is connected to the second data line 122 via the data selection circuit. The provision of a data selection circuit can reduce the power consumption of the display device and reduce the number of data signal output paths required by the driver chip 150, thereby expanding the range of driver chip 150 options. For example, the provision of a data selection circuit can enable a single driver chip 150 to simultaneously drive both the main screen 110 and the secondary screen 120.

[0110] When part of the second connection lines 123 are located in the first non-display area 112 , setting a data selection circuit can reduce the number of second connection lines 123 , thereby reducing the area of ​​the first non-display area 112 , thereby increasing the screen-to-body ratio of the main screen 110 .

[0111] Continue to refer Figure 7 The second non-display area is provided with a gate drive circuit 124, which is located on the second side of the secondary screen 120, opposite the first side 121. Placing the gate drive circuit 124 on the first side 121 increases the size of the border on the first side 121, thereby increasing the distance between the primary display area of ​​the primary screen and the secondary display area of ​​the secondary screen, resulting in a larger border. Placing the gate drive circuit 124 on the side opposite the first side 121 reduces the distance between the primary and secondary display areas, resulting in a better visual effect.

[0112] The second conductive layer also includes a signal line, one end of which is configured to be connected to the driver chip 150, and the other end of which is connected to the gate driver circuit 124 through the connection area 130 and the auxiliary display area. Exemplarily, the driver circuit has a dual SD layer structure, including a first SD layer and a second SD layer, with the second data line located in the second SD layer. The display panel 100 may further include a third SD layer (second conductive layer), which is located on a side of the second SD layer facing away from the first SD layer, and the signal line is located in the third SD layer.

[0113] The VSS line of the main screen 110 can be set in the first annular non-display area 112. The VSS line needs to be connected to the cathode of the light-emitting device. Since the display panel is a special-shaped screen, in order to prevent the mask from deforming when the cathode is connected, the connection structure may be poor. Figure 6 Cathode bonding is performed in the lower half of the annular first non-display area 112 .

[0114] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
