Description

Display panels, display modules, and electronic devices

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on January 24, 2024, with application number 202410104536.1 and application name “Display panel, display module and electronic device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of semiconductors, and in particular to a display panel, a display module, and an electronic device. Background Art

[0003] With the rapid development of smartphones and other devices, bezels are shrinking. Gate driver on array (GDA) circuits are typically located on both sides of the active area (AA). This significantly limits the design of the bezels around the AA area, as they must include all gate driver units and output wiring.

[0004] For terminal devices with rounded corners (R), the output of the gate driver unit in the rounded corner often cannot be directly aligned with the end of its control row as in straight-edge designs. The placement of the gate driver is restricted by the rounded corner border and the upper and lower borders. The presence of the gate driver unit in the rounded corner area requires a certain amount of fanout wiring, which makes it impossible to further reduce the rounded corner border and achieve an extremely narrow rounded corner border.

[0005] Summary of the Invention

[0006] Embodiments of the present application provide a display panel, a display module, and an electronic device for achieving an extremely narrow bezel design.

[0007] To achieve the above objectives, the present invention adopts the following technical solutions:

[0008] In a first aspect of an embodiment of the present application, a display panel is provided, comprising a display area and a peripheral area disposed around the display area; the display panel further comprising: a plurality of scan signal lines and a plurality of gate drive units, the plurality of scan signal lines being disposed within the display area; the peripheral area comprising a first side edge and a second side edge, the first side edge and the second side edge being connected by a first rounded corner, the first side edge being perpendicular to an extension direction of the scan signal lines, and the second side edge being parallel to the extension direction of the scan signal lines; the plurality of scan signal lines comprising: a first scan signal line and a second scan signal line; the plurality of gate drive units comprising: a first gate drive unit and a second gate drive unit, the second gate drive unit being disposed within the second side edge and the first gate drive unit being disposed within the first rounded corner, the first scan signal line being connected to the first gate drive unit, and the second scan signal line being connected to the second gate drive unit. Thus, by moving a portion of the gate drive units within the first rounded corner from the first rounded corner to the second side edge, the space occupied by the gate drive circuit unit within the first rounded corner can be reduced, thereby reducing the width of the first rounded corner and achieving an extremely narrow bezel design.

[0009] In an optional implementation, the first gate drive unit and the second gate drive unit are of the same type. Thus, the gate drive units within the first rounded corner and the second side edge can be of the same type. The first gate drive unit includes at least one of a red sub-pixel gate drive unit, a blue sub-pixel gate drive unit, and a green sub-pixel gate drive unit, and the second gate drive unit includes at least one of a red sub-pixel gate drive unit, a blue sub-pixel gate drive unit, and a green sub-pixel gate drive unit.

[0010] In one optional implementation, the first gate drive unit includes: a red sub-pixel gate drive unit, a blue sub-pixel gate drive unit, and a green sub-pixel gate drive unit, and the second gate drive unit includes: at least one of the red sub-pixel gate drive unit, the blue sub-pixel gate drive unit, and the green sub-pixel gate drive unit. Thus, the gate drive units include multiple types, and some of one or more gate drive units can be moved from the first rounded corner to the second side, providing greater design flexibility.

[0011] In an optional implementation, the display panel includes: a first connection line and a second connection line, the first connection line being disposed within the rounded corner, the second connection line being disposed within the display area, the second scan signal line being connected to one end of the first connection line, the other end of the first connection line being connected to one end of the second connection line, and the other end of the second connection line being connected to the second gate drive unit. Thus, the second scan signal line can be connected to the second gate drive unit via the first connection line and the second connection line, wherein the first connection line can be connected to the end of the second scan signal line, thereby eliminating the need for a hole in the display area for connection and reducing the impact on pixel design within the display area.

[0012] In one optional implementation, the second connection line includes a first portion and a second portion, the first portion being parallel to the second scan signal line, the second portion being perpendicular to the second scan signal line, the first portion being connected to the first connection line, and the second portion being connected to the second gate drive unit. Thus, the second connection line can include multiple portions, connecting the first connection line and the second gate drive unit in the display area while being compatible with intra-pixel wiring design.

[0013] In one optional implementation, the second connecting line further includes a third portion, wherein the third portion is an irregular fold line. Thus, the second connecting line can include an irregular fold line, providing greater flexibility in routing. Optionally, the third portion is connected to the first portion, or the third portion is connected to the second portion, or the third portion is connected to the first portion and the second portion.

[0014] In one optional implementation, the display panel further includes a third connection line disposed within the display area, through which the second scan signal line is connected to the second gate drive unit. Thus, the third connection line can be connected via a hole in the display area, eliminating the need to pass through rounded corners, thereby reducing routing complexity.

[0015] In one optional implementation, the third connecting line includes a fourth portion and a fifth portion, the fourth portion being parallel to the second scan signal line, the fifth portion being perpendicular to the second scan signal line, the fourth portion being connected to the second scan signal line, and the fourth portion being connected to the second gate drive unit via the fifth portion. Thus, the third connecting line can include multiple portions, connecting the second scan signal line and the second gate drive unit in the display area while being compatible with intra-pixel wiring design.

[0016] In an optional implementation, the third connecting line further includes: a sixth portion connecting the fourth portion and the fifth portion, the sixth portion being an irregular fold line. Thus, the shape of the third connecting line can include an irregular fold line, making the routing more flexible.

[0017] In one optional implementation, the display panel further includes a fourth connecting line disposed within the rounded corner, through which the first scan signal line is connected to the first gate drive unit. Thus, the connecting line connecting the second scan signal line and the second gate drive unit is mostly disposed within the display area, while the fourth connecting line is disposed only within the rounded corner. This reduces the space occupied by the connecting line and can further reduce the size of the rounded corner.

[0018] In one optional implementation, the display area includes N rows of second scan signal lines, and the peripheral area includes N columns of second gate drive units, wherein the i-th row of second scan signal lines is electrically connected to the i-th column of second gate drive units, where N is a positive integer, i is greater than or equal to 1, and i is less than or equal to N. Thus, there is a one-to-one correspondence between the N rows of second scan signal lines and the N columns of second gate drive units, which reduces routing difficulty and avoids crossover and confusion between the connection lines between multiple second scan signal lines and multiple second gate drive units.

[0019] In one optional implementation, the display area includes N rows of second scan signal lines, and the peripheral area includes N columns of second gate drive units, wherein the second scan signal line in the i-th row is electrically connected to the second gate drive unit in the N-(i-1)th column, where N is a positive integer, i is greater than or equal to 1, and i is less than or equal to N. Thus, there is a one-to-one correspondence between the N rows of second scan signal lines and the N columns of second gate drive units, which reduces routing difficulty and avoids cross-connection between multiple second scan signal lines and multiple second gate drive units.

[0020] In an optional implementation, the second scan signal line is disposed inside the portion of the rounded corner adjacent to the second side. Thus, the second gate drive unit corresponding to the rounded corner adjacent to the second side is moved inside the second side, shortening the distance between the second scan signal line corresponding to the rounded corner adjacent to the second side and the second gate drive unit. This reduces the length of the connection line between the second gate drive unit and the second scan signal line.

[0021] In an optional implementation, the second scan signal lines are arranged alternately with the first scan signal lines. Thus, the second gate drive unit connected to the second scan signal lines arranged alternately with the first scan signal lines is moved to the inside of the second side edge, which can evenly reduce the number of connecting lines within the rounded corner, thereby reducing the space occupied by the connecting lines and further reducing the size of the rounded corner.

[0022] In an optional implementation, the peripheral area further includes: a third side and a fourth side, the third side being parallel to the first side, the fourth side being parallel to the second side, and the third side and the fourth side being connected by a second rounded corner; the plurality of scan signal lines including: a third scan signal line and a fourth scan signal line, the third scan signal line and the fourth scan signal line being arranged inside the second rounded corner; the plurality of gate drive units including: a plurality of third gate drive units and a fourth gate drive unit, the third gate drive unit being arranged at the second rounded corner, the fourth gate drive unit being arranged at the fourth side, the third scan signal line being connected to the third gate drive unit, and the fourth scan signal line being connected to the fourth gate drive unit. Thus, the display panel of the present application may include multiple rounded corners, and some gate drive units within the rounded corners may be moved to two sides parallel to the scan signal lines, thereby reducing the space occupied by the gate drive circuit unit within the rounded corners, thereby reducing the width of the rounded corners and reducing the size of the rounded corners.

[0023] According to a second aspect of the embodiments of the present application, a display panel is provided, comprising: a display area and a peripheral area arranged around the display area, the display panel further comprising: a plurality of scan signals and a plurality of gate drive units, the plurality of scan signal lines being arranged within the display area; the peripheral area comprising a first side and a second side, the first side being perpendicular to an extension direction of the scan signal lines, and the second side being parallel to the extension direction of the scan signal lines; the plurality of gate drive units comprising: a first gate drive unit and a second gate drive unit, the first gate drive unit being arranged within the first side, the second gate drive unit being parallel to the extension direction of the scan signal lines; The element is arranged in the second side; the multiple scan signal lines include: a first scan signal line and a second scan signal line, the first scan signal line is connected to the first gate drive unit, and the second scan signal line is connected to the second gate drive unit; the display panel also includes: a first connecting line and a second connecting line, the first connecting line is arranged in the peripheral area, the second connecting line is arranged in the display area, one end of the second scan signal line is connected to one end of the first connecting line, the other end of the first connecting line is connected to one end of the second connecting line, and the other end of the second connecting line is connected to the second gate drive unit. Therefore, by arranging part of the gate drive unit in the second side, the space occupied by the gate drive circuit unit in the first side can be reduced, thereby reducing the width of the first side and reducing the size of the first side. The first scan signal line can be connected to the first gate drive unit via a connecting line, wherein the connecting line can be connected to the end of the first scan signal line, thereby eliminating the need to dig a hole in the display area for connection, reducing the impact on the pixel design in the display area.

[0024] In an optional implementation, the first gate drive unit and the second gate drive unit are of the same type. Thus, the gate drive units on the first side and the second side can be of the same type. The first gate drive unit includes at least one of a red sub-pixel gate drive unit, a blue sub-pixel gate drive unit, and a green sub-pixel gate drive unit, and the second gate drive unit includes at least one of a red sub-pixel gate drive unit, a blue sub-pixel gate drive unit, and a green sub-pixel gate drive unit.

[0025] In one optional implementation, the first gate drive unit includes: a red sub-pixel gate drive unit, a blue sub-pixel gate drive unit, and a green sub-pixel gate drive unit, and the second gate drive unit includes: at least one of the red sub-pixel gate drive unit, the blue sub-pixel gate drive unit, and the green sub-pixel gate drive unit. Thus, the gate drive units include multiple types, and some of one or more gate drive units can be moved from the first side to the second side, providing greater design flexibility.

[0026] In one optional implementation, the second connecting line includes a first portion and a second portion, the first portion being parallel to the scan signal line and the second portion being perpendicular to the scan signal line, the first portion being connected to the first connecting line, and the second portion being connected to the first portion and the first gate driver unit. Thus, the second connecting line can include multiple portions, connecting the first connecting line and the first gate driver unit in the display area while being compatible with intra-pixel wiring design.

[0027] In one optional implementation, the second connecting line further includes a third portion, wherein the third portion is an irregular fold line. Thus, the second connecting line can include an irregular fold line, providing greater flexibility in routing. Optionally, the third portion is connected to the first portion, or the third portion is connected to the second portion, or the third portion is connected to the first portion and the second portion.

[0028] According to a third aspect of the embodiments of the present application, a display panel is provided, comprising: a display area and a peripheral area arranged around the display area, the display panel further comprising: a plurality of scanning signal lines and a plurality of gate driving units, the plurality of scanning signal lines being arranged in the display area; the peripheral area comprising a first side and a second side, the first side being perpendicular to an extension direction of the scanning signal lines, and the second side being parallel to an extension direction of the scanning signal lines; the plurality of gate driving units comprising: a first gate driving unit and a second gate driving unit, the first gate driving unit being arranged in the first side, and the second gate driving unit being arranged in the second side; the plurality of scanning signal lines comprising: a first scanning signal line and a second scanning signal line, the first scanning signal line being connected to the first gate driving unit, and the second scanning signal line being connected to the second gate driving unit; the display panel further comprising: a first connecting line, the first connecting line being arranged in the display area, the second scanning signal line being connected to the second gate driving unit via the first connecting line. Thus, by placing part of the gate drive unit within the second side, the space occupied by the gate drive circuit unit within the first side can be reduced, thereby reducing the width and size of the first side. The second scan signal line can be connected to the second gate drive unit via a connecting line, wherein the connecting line does not need to pass through the first side, thereby reducing routing complexity.

[0029] In one optional implementation, the first connecting line includes a first portion and a second portion, the first portion being parallel to the scan signal line, the second portion being perpendicular to the scan signal line, the first portion being connected to the second scan signal line, and the first portion being connected to the second gate driving unit via the second portion. Thus, the connecting line can include multiple portions, connecting the first scan signal line and the first gate driving unit in the display area while being compatible with intra-pixel wiring design.

[0030] In an optional implementation, the third connecting line further includes: a third portion connecting the first portion and the second portion, the third portion being an irregular fold line. Thus, the shape of the connecting line can include an irregular fold line, making the routing more flexible.

[0031] A fourth aspect of the present application provides a display module comprising a cover plate and the display panel described above, wherein the cover plate is disposed on the light-emitting side of the display panel. Thus, the display module employing the display panel described above can reduce the size of rounded corners or side edges, thereby achieving an extremely narrow bezel design.

[0032] According to a fifth aspect of the present application, an electronic device is provided, comprising the display panel described above. Thus, the electronic device employing the display panel can reduce the size of rounded corners or side edges, thereby achieving an extremely narrow frame design.

[0033] The present application provides a display panel, a display module, and an electronic device. In some embodiments of the present application, the display panel adopts a right-angle design, which can move the peripheral areas of some gate drive units in the peripheral areas on the left and right sides of the display area to the peripheral areas above and below the display area. This can reduce the space occupied by the gate drive circuit units in the peripheral areas on the left and right sides of the display area, thereby reducing the width of the peripheral areas on the left and right sides of the display area, which is conducive to achieving an extremely narrow frame design.

[0034] In other embodiments of the present application, the display panel adopts a rounded corner design, which can move part of the gate driving unit within the rounded corner to the peripheral areas on the upper and lower sides of the display area, thereby reducing the space occupied by the gate driving circuit unit within the rounded corner of the display area, and further reducing the width of the rounded corner of the display area, which is conducive to achieving an extremely narrow frame design.

[0035] The gate drive units moved to the peripheral areas above and below the display area are connected to the scan signal lines via connecting wires. These connecting wires can be located only in the display area, and holes can be drilled in the display area to connect directly to the main body of the scan signal lines, eliminating the need to pass through rounded corners, shortening routing distances and reducing routing complexity. Alternatively, these connecting wires can be partially located in the display area and partially located in the peripheral area, with the portion located in the peripheral area connecting to the end of the scan signal line. This eliminates the need to drill holes in the display area for connection, reducing the impact on pixel design within the display area. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0057] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified with "first," "second," etc., may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0058] In addition, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to changes in the orientation of the components in the drawings.

[0059] In this application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0060] The embodiments of the present application provide a terminal. The terminal can be a product with a display interface, such as a tablet computer, a mobile phone, an e-reader, a remote control, a personal computer (PC), a laptop computer, a personal digital assistant (PDA), a vehicle-mounted device, an Internet TV, a wearable device, a television, and a smart display wearable product, such as a smart watch and a smart bracelet. The embodiments of the present application do not impose any special restrictions on the specific form of the above-mentioned terminal. For the sake of convenience of explanation, the following embodiments are all illustrated by taking a mobile phone as an example.

[0061] As shown in FIG1 , the terminal 1 includes a display screen 2 , a middle frame 3 , a housing (or battery cover, rear housing) 4 , and a cover plate 5 .

[0062] The display screen 2 has a light-emitting surface a1 through which a display image can be seen and a back surface a2 opposite to the light-emitting surface a1 . The back surface a2 of the display screen 2 is close to the middle frame 3 , and the cover plate 5 is arranged on the light-emitting surface a1 of the display screen 2 .

[0063] In one possible embodiment of the present application, the display screen 2 is an organic light-emitting diode (OLED) display screen. Since each light-emitting sub-pixel in the OLED display screen is provided with an electroluminescent layer, the OLED display screen can achieve self-luminescence after receiving an operating voltage.

[0064] The cover plate 5 is located on a side of the display screen 2 away from the middle frame 3 . The cover plate 5 may be, for example, a cover glass (CG), which may have a certain toughness.

[0065] The middle frame 3 is located between the display screen 2 and the housing 4. The surface of the middle frame 3 facing away from the display screen 2 is used to mount internal components such as the battery, printed circuit board (PCB), camera, and antenna. When the housing 4 and middle frame 3 are closed, these internal components are located between the housing 4 and the middle frame 3.

[0066] Next, referring to FIG. 2 , as shown in FIG. 2 , the display screen 2 is divided into a display area A. FIG.

[0067] In some embodiments, the display screen 2 further includes a peripheral area B located around the display area A.

[0068] The relative positional relationship and shape of the display area A and the peripheral area B are not limited. In the embodiment of the present application, the peripheral area B surrounding the display area A is used as an example for illustration.

[0069] The display area is an area that can display images or an operable area AA area (Active Area), that is, a visible area or an operable area, and this application does not limit this.

[0070] In some embodiments, as shown in FIG3 , the display area A includes a plurality of light-emitting pixels, each of which includes at least three light-emitting sub-pixels for displaying three primary colors. For example, each light-emitting pixel includes one red (R) sub-pixel, one green (G) sub-pixel, and one blue (B) sub-pixel. Alternatively, each light-emitting pixel includes one red sub-pixel, two green sub-pixels, and one blue sub-pixel.

[0071] For the sake of convenience, the above-mentioned multiple light-emitting sub-pixels are described in this application as an example of a matrix arrangement. It should be understood that the shape and arrangement of the light-emitting sub-pixels illustrated in this application are only illustrative and not limiting.

[0072] The display panel further includes: a plurality of scanning signal lines and a plurality of gate driver on array (Gate Driver On Array, gate driver) units. The plurality of scanning signal lines are arranged in the display area A, and the plurality of gate driver units are arranged in the peripheral area B.

[0073] Multiple rows of pixel circuits are provided within display area A. Each row of pixel circuits includes multiple pixel units, which are arranged laterally. The multiple pixel units are connected by row scanning signal lines, which are arranged in a first direction, i.e., laterally. Each row of pixel units requires a gate driving unit to drive it.

[0074] Referring now to Figure 3 , a gate drive circuit is comprised of several gate drive units, each corresponding to a scan signal line (or multiple scan signal lines). Specifically, the output of each gate drive unit is connected to a scan signal line, and the output of each gate drive unit is connected to the input of the next gate drive unit. This means that the gate signal (for writing pixel data or resetting / resetting signals, etc.) for each row of pixels in the display screen can be outputted not by an external driver IC but by a gate drive integrated circuit based on a TFT (Thin Film Transistor) design, achieving a progressive scan drive function.

[0075] For example, as shown in FIG4 , the scan signal lines may include: a Gate1 line connected to the first sub-pixel, a Gate2 line connected to the second sub-pixel, and a Gate3 line connected to the third sub-pixel. The gate driving unit includes: a GOA1 unit connected to the Gate1 line, a GOA2 unit connected to the Gate2 line, and a GOA3 unit connected to the Gate3 line.

[0076] In the example, the first sub-pixel, the second sub-pixel, and the third sub-pixel may be a red sub-pixel, a green sub-pixel, and a blue sub-pixel, respectively. Accordingly, the GOA1 unit, the GOA2 unit, and the GOA3 unit may be a red sub-pixel gate driving unit, a green sub-pixel gate driving unit, and a blue sub-pixel gate driving unit, respectively.

[0077] In some embodiments, Gate1 lines, Gate2 lines, and Gate3 lines are spaced apart along a first direction, GOA1 units, GOA2 units, and GOA3 units are spaced apart along a second direction, and a plurality of GOA1 units are arranged along the first direction, a plurality of GOA2 units are arranged along the first direction, and a plurality of GOA3 units are arranged along the first direction. The first direction is a direction perpendicular to the scan signal lines, and the second direction is a direction parallel to the scan signal lines.

[0078] 2 , the peripheral region includes a first side A1 and a second side A2 , and the first side A1 and the second side A2 are connected. The first side A1 is perpendicular to the extending direction of the scan signal line, and the second side A2 is parallel to the extending direction of the scan signal line.

[0079] In some embodiments, the peripheral region further includes a third side A3 and a fourth side A4, wherein the third side A3 is opposite the first side A1, and the fourth side A4 is opposite the second side A2. That is, the third side A3 is perpendicular to the direction in which the scan signal lines extend, and the fourth side A4 is parallel to the direction in which the scan signal lines extend.

[0080] As shown in FIG2 , the gate driving units are distributed on both sides of the display area A, namely, the first side A1 and the third side A3, and include N gate driving units. The longitudinal widths of the gate driving units are set to be consistent, and the driving units correspond one-to-one with the row pixel circuits, so that wiring can be facilitated and can be directly connected to the scanning signal lines through horizontal wiring from the driving unit 30.

[0081] In this implementation, the peripheral areas on both sides of the display area A (the first side A1 and the third side A3 ) include gate drive circuits, which results in significant limitations on the frame design and makes it impossible to achieve a local ultra-narrow frame.

[0082] To this end, the present application provides an improved display panel, which can configure the gate driving units corresponding to the row pixel circuits in the display area A at other positions except the left and right sides of the display area A.

[0083] Part of the gate driving units may be moved to other locations other than the left and right sides of the display area A, such as to the second side A2 of the peripheral area B or to the fourth side A4 of the peripheral area B. Part of the gate driving units may also be moved to the second side A2 of the peripheral area B and part of the gate driving units may be moved to the fourth side A4 of the peripheral area B. All of these fall within the scope of protection of this application.

[0084] In some embodiments, as shown in FIG5 , M of the N driving units are located on the second side A2 of the peripheral area B, M≤N, and the N driving units correspond one-to-one to N rows of pixel circuits, and both N and M are positive integers.

[0085] In other embodiments, as shown in FIG6 , the gate driving units corresponding to the rows of pixel circuits within the display area A may be arranged on the fourth side A4 of the peripheral area B, and K of the N driving units are located on the fourth side A4, where K≤N, the N driving units correspond one-to-one to the N rows of pixel circuits, and K and M are both positive integers.

[0086] In other embodiments, as shown in FIG7 , the gate driving units corresponding to the row pixel circuits in the display area A may be arranged on the fourth side A4 of the peripheral area B, and the gate driving units corresponding to the row pixel circuits in the display area A may be arranged on the second side A2 of the peripheral area B. For example, K driving units out of the N driving units are located on the fourth side A4, and M driving units out of the N driving units are located on the second side A2, where K≤N and M≤N, the N driving units correspond one-to-one to the N rows of pixel circuits, and K, N, and M are all positive integers.

[0087] The display panel provided in the embodiment of the present application sets part of the gate driving unit within the second side A2 and / or the fourth side A4, which can reduce the space occupied by the gate driving circuit unit within the first side A1 and the third side A3, thereby reducing the width of the first side A1 and the third side A3, which is conducive to achieving an extremely narrow frame design.

[0088] In the above embodiment, some gate driving units are arranged within the second side A2 and / or the fourth side A4, so that the positions of some gate driving units are changed. Therefore, it is necessary to set connecting lines to connect the above-mentioned gate driving units with changed positions and the corresponding scanning signal lines.

[0089] In some embodiments, the gate drive unit includes: a plurality of first GOA units, a plurality of second GOA units, and a plurality of third GOA units. In the present application, some gate drive units are moved to positions other than the left and right sides of the display area A. In some embodiments, some GOA1 units may be moved to positions other than the left and right sides of the display area A. In other embodiments, some GOA2 units may be moved to positions other than the left and right sides of the display area A. In other embodiments, some GOA3 units may be moved to positions other than the left and right sides of the display area A. Of course, two or three gate drive units among some GOA1 units, some GOA2 units, and some GOA3 units may be moved to positions other than the left and right sides of the display area A. These all fall within the scope of protection of the present application.

[0090] For example, as shown in FIG8 , part of the GOA3 units may be moved to the second side A2 of the peripheral area B. As shown in FIG8 , FIG8 .

[0091] In other embodiments, the gate driving unit includes: multiple GOA units of the same type. In this application, some gate driving units are moved to positions other than the left and right sides of the display area A. It can be that some GOA units of the same type are moved to positions other than the left and right sides of the display area A.

[0092] In some embodiments of the present application, referring to FIG. 8 , the display panel further includes: a first connecting line 201 and a second connecting line 202 .

[0093] The plurality of gate driving units include: a first gate driving unit 21 and a second gate driving unit 22 . The first gate driving unit 21 is disposed in the first side A1 , and the second gate driving unit 22 is disposed in the second side A2 .

[0094] In some embodiments, the first gate driving unit 21 includes: a plurality of GOA1 units, a plurality of GOA2 units, and a plurality of GOA3 units, and the second gate driving unit 22 includes: at least one of the GOA1 unit, the GOA2 unit, and the GOA3 unit. Thus, the gate driving unit includes multiple types, and some of the one or more gate driving units can be moved from the first side to the second side, which makes the design more flexible.

[0095] For example, the second gate driving unit 22 may include multiple GOA3 units, and the first gate driving unit 21 may include: multiple GOA1 units, multiple GOA2 units, and multiple GOA3 units. That is, some GOA3 units are moved from the first side A1 to the second side A2 of the peripheral area B.

[0096] In other embodiments, the first gate driving unit 21 and the second gate driving unit 22 are gate driving units of the same type. For example, the first gate driving unit 21 may include at least one of a GOA1 unit, a GOA2 unit, and a GOA3 unit, and correspondingly, the second gate driving unit 22 may include at least one of a GOA1 unit, a GOA2 unit, and a GOA3 unit.

[0097] For example, the first gate driving unit 21 includes a plurality of GOA1 units, and the second gate driving unit 22 includes a plurality of GOA1 units. That is, the first gate driving unit 21 and the second gate driving unit 22 may be the same type of GOA units.

[0098] The plurality of scan signal lines include: a first scan signal line 23 and a second scan signal line 24 . The first scan signal line 23 is connected to the first gate driving unit 21 via a second connection line 202 , and the second scan signal line 24 is connected to the second gate driving unit 22 via a first connection line 201 .

[0099] The embodiments of the present application do not limit the structure of the first connecting lines 201 and the second connecting lines 202. In some embodiments, referring to Figure 8, the first connecting lines 201 are perpendicular to the scan signal lines. That is, they do not enter the display area A laterally through the peripheral area B, but instead directly enter the display area A longitudinally to connect with the corresponding scan signal lines. As a result, portions of the first side A1 and the third side A3 are not provided with gate drive units or corresponding wiring, allowing for an extremely narrow bezel. The vertical and parallel terms used in this application may have errors, with the error range being less than 30°.

[0100] Therefore, the first connecting line does not need to pass through the first side A1, which shortens the routing distance and reduces the routing complexity.

[0101] The second connection line 202 is, for example, disposed within the first side A1 and the third side A3 .

[0102] In this embodiment, the connecting line connecting the first scan signal line and the first gate driving unit is arranged in the display area, and only the second connecting line is arranged in the first side A1 and the third side A3, which reduces the space occupied by the connecting line and can further reduce the size of the first side A1 and the third side A3.

[0103] In other embodiments, as shown in Figure 9, the first connecting line 201 includes: a first part 2011 and a second part 2012, the first part 2011 is parallel to the first scanning signal line 23, the second part 2012 is perpendicular to the first scanning signal line 23, the first part 2011 is connected to the first scanning signal line 23, and the first part 2011 is connected to the first gate driving unit 21 through the second part 2012.

[0104] Thus, the first connection line may include a plurality of parts, and while connecting the first connection line and the first gate driving unit in the display area, it may be compatible with the intra-pixel wiring design.

[0105] In some examples of this embodiment, the first portion 2011 and the second portion 2012 are both disposed in the display area. In other examples of this embodiment, the first portion 2011 and / or the second portion 2012 may also extend into the peripheral area B.

[0106] In some other embodiments, as shown in Figure 10, the first connecting line 201 includes: a first part 2011, a second part 2012 and a third part 2013, the first part 2011 is parallel to the first scanning signal line 23, the second part 2012 and the third part 2013 are both perpendicular to the first scanning signal line 23, the third part 2013 is connected to the first scanning signal line 23, the first part 2011 is connected to the third part 2013, and the first part 2011 is connected to the first gate driving unit 21 through the second part 2012.

[0107] Thus, the first connecting line includes a third portion perpendicular to the scanning signal line, thereby preventing the first connecting line from overlapping with the scanning signal line and reducing interference between the scanning signal line and the first connecting line.

[0108] In addition, in other embodiments, the first connecting line 201 further includes: a fourth portion, and the fourth portion can be an irregular folded line structure.

[0109] In some embodiments, the fourth portion may be connected to the first portion 2011 , in other embodiments, the fourth portion may be connected to the second portion 2012 , and in other embodiments, the fourth portion may be connected to the first portion 2011 and the second portion 2012 .

[0110] Therefore, the shape of the first connecting line may include an irregular fold line, making the routing more flexible.

[0111] In other embodiments of the present application, as shown in Figure 11, referring to Figure 9, the display panel also includes: a third connecting line 203, the third connecting line 203 is arranged in the peripheral area, the first scanning signal line 23 is connected to one end of the third connecting line 203, the other end of the third connecting line 203 is connected to one end of the first connecting line 201, and the other end of the first connecting line 201 is connected to the gate driving unit.

[0112] Thus, the third connection line 203 can be connected to the end of the first scan signal line 23, thereby eliminating the need to dig a hole in the display area for connection, thereby reducing the impact on the pixel design in the display area.

[0113] The embodiment of the present application does not limit the types of the first connection lines 201, the second connection lines 202, and the third connection lines 203. In some embodiments, the first connection lines 201, the second connection lines 202, and the third connection lines 203 can be redundant metal lines already in the TFT design, or can be additional metal lines. The first connection lines 201, the second connection lines 202, and the third connection lines 203 can be introduced through the metal layer where the gate wiring is located in the display area A, or can enter the display area A through other layers other than the metal layer where the gate wiring is located, and then be connected to the corresponding scan signal lines through other methods such as punching.

[0114] The display panel provided in the embodiment of the present application can set part of the gate driving unit within the second side A2 and / or the fourth side A4, and connect the part of the gate driving unit and the corresponding scanning signal line through a connecting line, which can reduce the space occupied by the gate driving circuit unit within the first side A1 and the third side A3, thereby reducing the width of the first side A1 and the third side A3 and reducing the size of the first side A1 and the third side A3.

[0115] In the above embodiment, the display panel adopts a right-angle structure. In other embodiments, as shown in FIG12 , the display panel may adopt a rounded corner R design. For terminal devices with a rounded corner R design, the output end of the gate drive unit is located at the rounded corner R, and fanout wiring is required to connect the drive unit to the gate lines within the display area A, resulting in the border being unable to be further reduced.

[0116] To this end, the present application provides an improved display panel, which can configure some gate driving units within the rounded corner R at other positions except the left and right sides of the display area A and the rounded corner R.

[0117] Part of the gate driving units may be moved to other locations except the left and right sides of the display area A and the rounded corner R, such as to the second side A2 of the peripheral area B or to the fourth side A4 of the peripheral area B. Alternatively, part of the gate driving units may be moved to the second side A2 of the peripheral area B, and part of the gate driving units may be moved to the fourth side A4 of the peripheral area B. All of these fall within the scope of protection of this application.

[0118] The display panel provided in the present application moves part of the gate driving unit within the rounded corner R from the rounded corner R to the second side A2 and / or the fourth side A4, which can reduce the space occupied by the gate driving circuit unit within the rounded corner R, thereby reducing the width of the rounded corner R and reducing the size of the rounded corner R.

[0119] In some embodiments, the gate driving unit includes: a plurality of GOA1 units, a plurality of GOA2 units, and a plurality of GOA3 units. In the present application, some of the gate driving units are moved to positions other than the left and right sides of the display area A and the rounded corner R. In some embodiments, some of the GOA1 units may be moved to positions other than the left and right sides of the display area A and the rounded corner R. In other embodiments, as shown in FIG14 , some of the GOA2 units may be moved to positions other than the left and right sides of the display area A and the rounded corner R. In other embodiments, as shown in FIG17 , some of the GOA3 units may be moved to positions other than the left and right sides of the display area A and the rounded corner R. Of course, two or three gate driving units among some of the GOA1 units, some of the GOA2 units, and some of the GOA3 units may be moved to positions other than the left and right sides of the display area A and the rounded corner R. These all fall within the scope of protection of the present application.

[0120] In other embodiments, the gate driving unit includes: multiple GOA units of the same type. In this application, some gate driving units are moved to positions other than the left and right sides of the display area A. It can be that some GOA units of the same type are moved to positions other than the left and right sides of the display area A.

[0121] 13 and 14 , some GOA2 units may be moved to the second side A2 of the peripheral area B. Alternatively, some GOA3 units may be moved to the second side A2 of the peripheral area B as shown in FIG17 .

[0122] The following describes the circuits and wiring within the improved display panel, using Figures 13-20. As shown in Figure 13, the display panel includes a display area A and a peripheral area B surrounding the display area. The display panel also includes a plurality of scan signal lines disposed within the display area A and a plurality of gate drive units.

[0123] The peripheral area includes a first side A1 and a second side A2, and the first side A1 and the second side A2 are connected by a first rounded corner R1. The first side A1 is perpendicular to the extension direction of the scan signal line, and the second side A2 is parallel to the extension direction of the scan signal line.

[0124] In some embodiments, the peripheral area also includes: a third side A3 and a fourth side A4, the third side A3 is opposite to the first side A1, the fourth side A4 is opposite to the second side A2, the third side A3 and the fourth side A4 are connected by a second rounded corner R2, the first side A1 and the fourth side A4 are connected by a third rounded corner R3, and the third side A3 and the second side A2 are connected by a fourth rounded corner R4.

[0125] In some embodiments, when some gate driving units within the rounded corner R are configured at positions other than the left and right sides of the display area A and the rounded corner R, they can be moved to the sides relatively close to the rounded corner R, thereby reducing the difficulty of routing.

[0126] For example, as shown in FIG13 , part of the gate driving units in the first rounded corner R1 may be moved to the second side A2 , and / or part of the gate driving units in the fourth rounded corner R4 may be moved to the second side A2 .

[0127] Part of the gate driving units in the second rounded corner R2 may be moved to the fourth side A4, and / or part of the gate driving units in the third rounded corner R3 may be moved to the fourth side A4.

[0128] The following description takes the layout of the gate driving unit and the scanning signal line corresponding to the first rounded corner R1 as an example. The layout of the gate driving unit and the scanning signal line corresponding to other rounded corners can refer to the following description and will not be repeated here.

[0129] As shown in FIG14 , the plurality of gate driving units include a third gate driving unit 25 and a fourth gate driving unit 26 . The third gate driving unit 25 is disposed in the first rounded corner, and the fourth gate driving unit 26 is disposed in the second side A2 .

[0130] In some embodiments, the third gate driving unit 25 includes: a plurality of GOA1 units, a plurality of GOA2 units, and a plurality of GOA3 units, and the fourth gate driving unit 26 includes: at least one of the GOA1 unit, the GOA2 unit, and the GOA3 unit. Thus, the gate driving unit includes multiple types, and some of the one or more gate driving units can be moved from the first side to the second side, which makes the design more flexible.

[0131] For example, as shown in FIG17 , the fourth gate driving unit 26 includes a plurality of GOA3 units, and the third gate driving unit 25 includes a plurality of GOA1 units, a plurality of GOA2 units, and a plurality of GOA3 units. That is, some of the GOA3 units are moved from the first side A1 to the second side A2 of the peripheral area B.

[0132] In other embodiments, the third gate driving unit 25 and the fourth gate driving unit 26 are gate driving units of the same type. For example, the third gate driving unit 25 may include at least one of a GOA1 unit, a GOA2 unit, and a GOA3 unit, and correspondingly, the fourth gate driving unit 26 may include at least one of a GOA1 unit, a GOA2 unit, and a GOA3 unit.

[0133] 13 , the fourth gate driving unit 26 includes multiple GOA1 units, and the third gate driving unit 25 includes multiple GOA1 units. That is, the third gate driving unit 25 and the fourth gate driving unit 26 may be the same type of GOA units.

[0134] The plurality of scanning signal lines include a third scanning signal line 27 and a fourth scanning signal line 28 . The third scanning signal line 27 and the fourth scanning signal line 28 are disposed inside the first rounded corner.

[0135] As shown in FIG. 14 , the third scanning signal line 27 is connected to the third gate driving unit 25 , and the fourth scanning signal line 28 is connected to the fourth gate driving unit 26 .

[0136] The display panel provided in the embodiment of the present application moves part of the gate driving unit within the rounded corner from the rounded corner to the second side, which can reduce the space occupied by the gate driving circuit unit within the rounded corner, thereby reducing the width of the rounded corner and achieving an extremely narrow frame design.

[0137] In some embodiments, the fourth scan signal line 28 can be disposed inside the portion of the rounded corner adjacent to the second side A2. That is, the fourth gate driving unit corresponding to the rounded corner adjacent to the second side can be moved inside the second side. This reduces the distance between the fourth scan signal line and the fourth gate driving unit, thereby reducing the length of the connecting line between the fourth scan signal line and the fourth gate driving unit and simplifying the design.

[0138] In some embodiments of the present application, the fourth scan signal line 28 is alternately arranged with the third scan signal line 27. Thus, by moving the fourth gate driving unit to the second side, the number of connecting lines in the rounded corner can be evenly reduced, thereby reducing the space occupied by the connecting lines and further reducing the size of the rounded corner.

[0139] The wiring structure and circuit of the first rounded corner are used as an example for explanation below. The wiring structure and circuit of the second rounded corner can refer to the first rounded corner and will not be described in detail below.

[0140] The embodiment of the present application does not limit the corresponding relationship between the fourth scanning signal line 28 and the fourth gate driving unit 26 .

[0141] In some embodiments, as shown in Figures 14 and 17, the display area includes N rows of fourth scan signal lines 28, and the peripheral area includes N columns of fourth gate driving units 26. The fourth scan signal line 28 in the i-th row is electrically connected to the fourth gate driving unit 26 in the i-th column, where N is a positive integer, i is greater than or equal to 1, and i is less than or equal to N. Thus, when i = 1, the fourth scan signal line 28 in the first row is connected to the fourth gate driving unit 26 in the first column; when i = 2, the fourth scan signal line 28 in the second row is connected to the fourth gate driving unit 26 in the second column; and when i = N, the fourth scan signal line 28 in the N-th row is connected to the fourth gate driving unit 26 in the N-th column. This ensures a one-to-one correspondence between the N rows of fourth scan signal lines and the N columns of fourth gate driving units, reducing routing complexity and preventing crossover and confusion between the connecting lines between multiple fourth scan signal lines and multiple fourth gate driving units.

[0142] In other embodiments, as shown in FIG18 , the display area includes N rows of fourth scan signal lines 28, and the peripheral area includes N columns of fourth gate driving units 26, wherein the fourth scan signal line 28 in the i-th row is electrically connected to the fourth gate driving unit 26 in the N-(i-1)th column, where N is a positive integer, i is greater than or equal to 1, and i is less than or equal to N. Thus, when i=1, the fourth scan signal line 28 in the 1st row is connected to the fourth gate driving unit 26 in the Nth column; when i=2, the fourth scan signal line 28 in the 2nd row is connected to the fourth gate driving unit 26 in the (N-1)th column; and when i=N, the fourth scan signal line 28 in the Nth row is connected to the fourth gate driving unit 26 in the 1st column. Thus, there is a one-to-one correspondence between the N rows of fourth scan signal lines and the N columns of fourth gate driving units, which reduces routing difficulty and avoids crossover and confusion between the connecting lines between multiple fourth scan signal lines and multiple fourth gate driving units.

[0143] In other embodiments, any fourth scanning signal line 28 may be connected to any fourth gate driving unit 26, or, as shown in FIG19 , multiple fourth scanning signal lines 28 may be connected to one fourth gate driving unit 26, all of which fall within the scope of protection of the present application.

[0144] In the above embodiment, some gate driving units are arranged within the second side A2 and / or the fourth side A4, so that the positions of some gate driving units are changed. Therefore, it is necessary to set connecting lines to connect the above-mentioned gate driving units with changed positions and the corresponding scanning signal lines.

[0145] In some embodiments of the present application, referring to FIG. 14 , the display panel further includes a fourth connecting line 204 and a fifth connecting line 205 .

[0146] The third scan signal line 27 is connected to the third gate driving unit 25 via a fourth connection line 204 , and the fourth scan signal line 28 is connected to the fourth gate driving unit 26 via a fifth connection line 205 .

[0147] The present embodiment does not limit the structure of the fourth connection line 204 and the fifth connection line 205. In some embodiments, referring to Figure 14, the fifth connection line 205 is perpendicular to the scan signal line. That is, it does not enter the display area A laterally through the peripheral area B, but instead directly enters the display area A vertically and connects to the corresponding scan signal line. As a result, the area around the rounded corner R is not equipped with a gate drive unit and does not contain corresponding wiring, thus allowing for an extremely narrow bezel. The vertical and parallel terms in this application may have errors, with an error range of less than 30°.

[0148] Therefore, the fifth connecting line 205 does not need to pass through the rounded corner, which reduces the wiring length and simplifies the design.

[0149] The fourth connecting line 204 is disposed within the rounded corner R, for example.

[0150] In this embodiment, the connection line connecting the fourth scan signal line 28 and the fourth gate driving unit 26 is set in the display area, and only the fourth connection line 204 is set in the rounded corner, which reduces the space occupied by the connection line and can further reduce the size of the rounded corner.

[0151] In other embodiments, as shown in Figure 15, the fifth connecting line 205 includes: a first sub-portion 2051 and a second sub-portion 2052, the first sub-portion 2051 is parallel to the third scanning signal line 27, the second sub-portion 2052 is perpendicular to the third scanning signal line 27, the first sub-portion 2051 is connected to the third scanning signal line 27, and the first sub-portion 2051 is connected to the third scanning signal line 27, and the first sub-portion 2051 is connected to the third gate driving unit 25 through the second sub-portion 2052.

[0152] In some examples of this embodiment, the first sub-portion 2051 and the second sub-portion 2052 are both disposed in the display area. In other examples of this embodiment, the first sub-portion 2051 and / or the second sub-portion 2052 may also extend into the peripheral area B.

[0153] Therefore, the fifth connecting line may include multiple parts, connecting the fourth scanning signal line 28 and the fourth gate driving unit 26 in the display area, thereby reducing the difficulty of wiring.

[0154] In some other embodiments, as shown in Figure 16, the fifth connecting line 205 includes: a first sub-portion 2051, a second sub-portion 2052 and a third sub-portion 2053, the first sub-portion 2051 is parallel to the third scanning signal line 27, the second sub-portion 2052 and the third sub-portion 2053 are both perpendicular to the third scanning signal line 27, the third sub-portion 2053 is connected to the third scanning signal line 27, the first sub-portion 2051 is connected to the third sub-portion 2053, and the first sub-portion 2051 is connected to the third gate driving unit 25 through the second sub-portion 2052.

[0155] Therefore, the fifth connecting line 205 includes a third portion perpendicular to the scanning signal line, which prevents the fifth connecting line 205 from overlapping with the scanning signal line and reduces interference between the scanning signal line and the fifth connecting line 205 .

[0156] In addition, in other embodiments, the fifth connecting line 205 further includes: a fourth sub-portion, and the fourth sub-portion can be an irregular folded line structure.

[0157] In some embodiments, the fourth subsection may be connected to the first subsection 2051 , in other embodiments, the fourth subsection may be connected to the second subsection 2052 , and in other embodiments, the fourth subsection may connect the first subsection 2051 and the second subsection 2052 .

[0158] Therefore, the shape of the fifth connection line 205 may include an irregular fold line, making the routing more flexible.

[0159] In other embodiments of the present application, as shown in Figure 17, the display panel also includes: a sixth connecting line 206, which is arranged in the peripheral area, the fourth scanning signal line 28 is connected to one end of the sixth connecting line 206, the other end of the sixth connecting line 206 is connected to one end of the fifth connecting line 205, and the other end of the fifth connecting line 205 is connected to the gate driving unit.

[0160] Thus, the sixth connection line 206 can be connected to the end of the fourth scan signal line 28, thereby eliminating the need to dig a hole in the display area for connection, thereby reducing the impact on the pixel design in the display area.

[0161] The embodiment of the present application does not limit the types of the fourth connection line 204, the fifth connection line 205, and the sixth connection line 206. In some embodiments, the fourth connection line 204, the fifth connection line 205, and the sixth connection line 206 can be redundant metal lines already in the TFT design, or can be additional metal lines. The fourth connection line 204, the fifth connection line 205, and the sixth connection line 206 can be introduced through the metal layer where the gate wiring is located in the display area A, or can enter the display area A through other layers other than the metal layer where the gate wiring is located, and then be connected to the corresponding scan signal lines through other methods such as punching.

[0162] The display panel provided in the embodiment of the present application can set part of the gate driving unit within the second side A2 and / or the fourth side A4, and connect the part of the gate driving unit and the corresponding scanning signal line through a connecting line, which can reduce the space occupied by the gate driving circuit unit within the rounded corner R, thereby reducing the width of the rounded corner R and reducing the size of the rounded corner R.

[0163] In some embodiments, the present application further provides a display module, which includes at least a cover plate and the display panel as described above, wherein the cover plate is arranged on the light-emitting side of the display panel.

[0164] The present application provides a display panel, a display module, and an electronic device. In some embodiments of the present application, the display panel adopts a right-angle design, which can move the peripheral areas of some gate drive units in the peripheral areas on the left and right sides of the display area to the peripheral areas above and below the display area. This can reduce the space occupied by the gate drive circuit units in the peripheral areas on the left and right sides of the display area, thereby reducing the width of the peripheral areas on the left and right sides of the display area, which is conducive to achieving an extremely narrow frame design.

[0165] In other embodiments of the present application, the display panel adopts a rounded corner design, which can move part of the gate driving unit within the rounded corner to the peripheral areas on the upper and lower sides of the display area, thereby reducing the space occupied by the gate driving circuit unit within the rounded corner of the display area, and further reducing the width of the rounded corner of the display area, which is conducive to achieving an extremely narrow frame design.

[0166] The gate drive units moved to the peripheral areas above and below the display area are connected to the scan signal lines via connecting wires. These connecting wires can be located only in the display area, and holes can be drilled in the display area to connect directly to the main body of the scan signal lines. This connection eliminates the need to pass through rounded corners, shortening routing distances, reducing routing complexity, and simplifying the design. Alternatively, the connecting wires can be partially located in the display area and partially located in the peripheral area, with the portion located in the peripheral area connecting to the end of the scan signal line. This eliminates the need to drill holes in the display area for connection, reducing the impact on pixel design within the display area.

[0167] In the embodiments shown in Figures 14 to 18 above, one gate driving unit is connected to one scan signal line. In other embodiments, as shown in Figures 19 and 20, one gate driving unit can be connected to two scan signal lines. Of course, in other embodiments, one gate driving unit can also be connected to more than two scan signal lines. All of these fall within the scope of protection of this application.

[0168] The connection between a gate driving unit and two scanning signal lines is described below with reference to FIG19 and FIG20.

[0169] As shown in FIG19 , two scan signal lines (28a, 28b) are connected to a gate driving unit 26a via a fifth connecting line 205. The fifth connecting line 205 includes a first sub-connecting line 205a and a second sub-connecting line 205b. One scan signal line 28a is connected to the gate driving unit 26a via the first sub-connecting line 205a, and the other scan signal line 28b is connected to the gate driving unit 26a via the second sub-connecting line 205b.

[0170] In FIG19 , the fifth connection line 205 is divided into two connection lines within the second side A2B: a first sub-connection line 205a and a second sub-connection line 205b. Both connection lines pass through the second side A2B and the display area A, and are connected to the scan signal line 28a and the scan signal line 28b respectively.

[0171] That is, the gate driving unit 26a outputs two connecting lines (first sub-connecting line 205a and second sub-connecting line 205b) in the peripheral area B, and the two connecting lines (first sub-connecting line 205a and second sub-connecting line 205b) are respectively connected to two rows of scanning signal lines (scanning signal line 28a, scanning signal line 28b).

[0172] As shown in Figure 20, referring to Figure 19, the fifth connecting line 205 is a line within the second side A2B, and is divided into two connecting lines within the display area A: a first sub-connecting line 205a and a second sub-connecting line 205b. Both connecting lines pass through the display area A and are respectively connected to the scanning signal line 28a and the scanning signal line 28b.
