[0013] 为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。 DETAILED DESCRIPTION OF THE INVENTION [0013] In order to more clearly understand the technical features, objects and advantages of the present invention, the embodiments of the present invention are described in detail with reference to the accompanying drawings.

[0014] 如图 1所示，本发明一实施例的显示面板，包括面板基板 10、设置在面板基板 1[0014] As shown in FIG. 1, a display panel according to an embodiment of the present invention includes a panel substrate 10 and is disposed on the panel substrate 1

0上的显示区 20、设置在面板基板 10上的两个 GOA驱动电路 30 (栅扫描线驱动电路）和一个 EOA驱动电路 40 (发光扫描线驱动电路）。The display area 20 on 0, two GOA drive circuits 30 (gate scan line drive circuit) and one EOA drive circuit 40 (light-emitting scan line drive circuit) provided on the panel substrate 10.

[0015] 显示区 20位于面板基板 10的中部位置，显示区 20外围与面板基板 10的边缘之间的区域形成边框区域。两个 GO A驱动电路 30分别设置在显示区 20相对两侧的边框区域内， EOA驱动电路 40设置在显示区 20另外一侧的边框区域内，从而 EOA 驱动电路 40和 GO A驱动电路 30位于显示区 20的不同侧，也位于不同的边框区域内，方便显示区 20相对两侧的边框区域宽度的减小设置，形成窄边框。[0015] The display area 20 is located at a central portion of the panel substrate 10, and a region between the periphery of the display area 20 and the edge of the panel substrate 10 forms a frame area. Two GO A driving circuits 30 are respectively disposed in the frame areas on opposite sides of the display area 20, and the EOA driving circuit 40 is disposed in the frame area on the other side of the display area 20, so that the EOA driving circuit 40 and the GO A driving circuit 30 are located. The different sides of the display area 20 are also located in different frame areas, which facilitates the reduction of the width of the frame area on opposite sides of the display area 20 to form a narrow frame.

[0016] GOA驱动电路 30与对应的面板基板 10边缘之间的间隔形成封装区 11， EOA驱动电路 40与对应的面板基板 10边缘之间的间隔也形成封装区 12。[0016] The spacing between the GOA driving circuit 30 and the edge of the corresponding panel substrate 10 forms a package area 11, and the space between the EOA driving circuit 40 and the edge of the corresponding panel substrate 10 also forms the package area 12.

[0017] 具体地，显示区 20包括多组平行排列的像素组 50，每一组像素组 50分别通过栅扫描线信号线 31与 GOA驱动电路 30连接，并且通过发光扫描信号线 41与 EOA驱动电路 40连接。[0017] Specifically, the display area 20 includes a plurality of sets of pixel groups 50 arranged in parallel, each of which is connected to the GOA driving circuit 30 through the gate scanning line signal line 31, and is driven by the illuminating scanning signal line 41 and EOA. Circuit 40 is connected.

[0018] 每一组像素组 50包括多个依次排布的像素单位 51 (即单个像素）。如图 1所示面板结构的放置方向，本实施例中，多组像素组 50沿着显示区 20自上而下顺序排布。多组像素组 50的多个像素单位 51—一对齐，从而形成多行多列排布的像素单位组合。两个 GOA驱动电路 30设置在显示区 20左右两侧的边框区域内， EO A驱动电路 40设置在显示区 20上侧的边框区域内。[0018] Each set of pixel groups 50 includes a plurality of pixel units 51 (ie, a single pixel) arranged in sequence. In the embodiment, the plurality of groups of pixel groups 50 are arranged in the order from top to bottom along the display area 20. A plurality of pixel units 51 of the plurality of sets of pixel groups 50 are aligned to form a plurality of rows and columns of images Prime unit combination. Two GOA driving circuits 30 are disposed in the frame area on the left and right sides of the display area 20, and the EO A driving circuit 40 is disposed in the frame area on the upper side of the display area 20.

[0019] 每一个 GOA驱动电路 30包括多个依次相接的 GOA驱动电路单元，多个 GOA驱动电路单元的排布方向与多组像素组 50的排布方向一致，如图 1所示的纵向排布；每一个 GOA驱动电路单元对应连接一组像素组 50。 EOA驱动电路 40包括多个依次相接的 EOA驱动电路单元，多个 EOA驱动电路单元的排布方向与像素组 50 中的多个像素单位 51的横向排布方向一致，每一个 EOA驱动电路单元也对应连接一组像素组 50。[0019] Each of the GOA driving circuits 30 includes a plurality of GOA driving circuit units that are sequentially connected, and the arrangement direction of the plurality of GOA driving circuit units is consistent with the arrangement direction of the plurality of groups of pixel groups 50, as shown in FIG. Arrangement; each GOA driving circuit unit is correspondingly connected to a group of pixel groups 50. The EOA driving circuit 40 includes a plurality of EOA driving circuit units that are sequentially connected, and the arrangement direction of the plurality of EOA driving circuit units is aligned with the lateral arrangement direction of the plurality of pixel units 51 in the pixel group 50, and each EOA driving circuit unit A set of pixel groups 50 is also connected.

[0020] 将 Y方向表示纵向方向， X方向表示横向方向，像素单位 51的高度和宽度均为 A [0020] The Y direction represents the longitudinal direction, the X direction represents the lateral direction, and the pixel unit 51 has both the height and the width A.

， X表示 X方向上像素单位 51的个数， y表示 Y方向上像素单位 51的个数。在像素单位组合中，当 Y方向的像素单位 51行数与 X方向像素单位 51的列数一致吋， GO A驱动电路单元的高度与 EOA驱动电路单元的宽度设置一致，均为 A; GOA驱动电路 30的总高度为 A*y， EOA驱动电路 40的总宽度为 A*x，两者数值一致。当 Y 方向的像素单位 51行数大于 X方向像素单位 51的列数吋， GOA驱动电路单元的高度为 A， GOA驱动电路 30的总高度为 A*y , X represents the number of pixel units 51 in the X direction, and y represents the number of pixel units 51 in the Y direction. In the pixel unit combination, when the number of pixel units 51 in the Y direction coincides with the number of columns in the X direction pixel unit 51, the height of the GO A driving circuit unit is the same as the width setting of the EOA driving circuit unit, both are A; GOA The total height of the drive circuit 30 is A*y, and the total width of the EOA drive circuit 40 is A*x, and the values are the same. When the pixel unit 51 line number in the Y direction is larger than the number of columns in the X direction pixel unit 51, the height of the GOA driving circuit unit is A, and the total height of the GOA driving circuit 30 is A*y

，而 EOA驱动电路单元的宽度为 A* (x/y) ， EOA驱动电路 40的总宽度设置为 A* χ/y* y=xA。 The width of the EOA driver circuit unit is A* (x/y), and the total width of the EOA driver circuit 40 is set to A* χ/y* y=xA.

[0021] 例如，在一个分辨率 720*1280的显示区 20中，像素单位 51的高度和宽度均为 A ，显示区 20的长和高分别为 X和 y， x=720A, y=1280A。一个 EOA驱动电路单元的宽度为 A* (720/1280) ， EO A驱动电路 40的总宽度则为 A* (720/1280) *1280 ，即为 720A。 [0021] For example, in a display area 20 of resolution 720*1280, the height and width of the pixel unit 51 are both A, and the length and height of the display area 20 are X and y, x=720A, y=1280A, respectively. The width of an EOA driver circuit unit is A* (720/1280), and the total width of the EO A driver circuit 40 is A* (720/1280) *1280, which is 720A.

[0022] 在每一组像素组 50中，栅扫描线信号线 31将多个像素单位 51串联，栅扫描线信号线 31的两端分别连接两个 GO A驱动电路 30。 [0022] In each of the sets of pixel groups 50, the gate scan line signal line 31 connects a plurality of pixel units 51 in series, and both ends of the gate scan line signal line 31 are connected to the two GO A drive circuits 30, respectively.

[0023] 在每一组像素组 50中，发光扫描信号线 41包括第一信号线 411和第二信号线 412[0023] In each group of pixel groups 50, the light-emission scanning signal line 41 includes a first signal line 411 and a second signal line 412.

。第一信号线 411将多个像素单位 51串联连接，第二信号线 412—端连接第一信号线 411，另一端连接 E0A驱动电路 40。. The first signal line 411 connects a plurality of pixel units 51 in series, the second signal line 412 is connected to the first signal line 411, and the other end is connected to the E0A driving circuit 40.

[0024] 进一步地，栅扫描线信号线 31和发光扫描信号线 41均由金属层形成。金属层为Further, the gate scanning line signal line 31 and the luminescent scanning signal line 41 are each formed of a metal layer. Metal layer is

Al、 Mo、 Cu、 Ti、 Mo合金、 GZ0、 ZIO等金属、合金、导体金属氧化物中至少一种制成。At least Al, Mo, Cu, Ti, Mo alloy, GZ0, ZIO, etc., metals, alloys, and conductor metal oxides One made.

[0025] 结合图 1-3所示，发光扫描信号线 41的第一信号线 411由第一金属层 100形成，发光扫描信号线 41的第二信号线 412由第二金属层 200形成，栅扫描线信号线 31 由第三金属层（未图示）形成。第二信号线 412在导电性能高于第一信号线 411 ，因此可采用导电性好的材料如 A1制成，而第一信号线 411可采用 Mo制成。当然，第一信号线 411也可采用与第二信号线 412相同的材料制成。 As shown in FIG. 1-3, the first signal line 411 of the light-emitting scanning signal line 41 is formed by the first metal layer 100, and the second signal line 412 of the light-emitting scanning signal line 41 is formed by the second metal layer 200. The scanning line signal line 31 is formed of a third metal layer (not shown). The second signal line 412 has a higher electrical conductivity than the first signal line 411, and thus may be made of a conductive material such as A1, and the first signal line 411 may be made of Mo. Of course, the first signal line 411 can also be made of the same material as the second signal line 412.

[0026] 第一信号线 411的第一金属层 100和栅扫描线信号线 31的第三金属层位于同一设置面上。在显示区 20中，第一信号线 411和栅扫描线信号线 31相平行间隔，两者不相交，因此不连接；第二信号线 412与第一信号线 411相垂直。第二金属层 200 叠设在第一金属层 100和第三金属层上，与第一金属层 100相接连通，与第三金属层相绝缘。 The first metal layer 100 of the first signal line 411 and the third metal layer of the gate scan line signal line 31 are located on the same setting surface. In the display area 20, the first signal line 411 and the gate scanning line signal line 31 are spaced apart in parallel, and the two do not intersect, and thus are not connected; the second signal line 412 is perpendicular to the first signal line 411. The second metal layer 200 is stacked on the first metal layer 100 and the third metal layer, is in communication with the first metal layer 100, and is insulated from the third metal layer.

[0027] 具体地，由于第二信号线 412的第二金属层 200—端延伸至连接 E0A驱动电路 40 ，跨过栅扫描线信号线 31的第三金属层，因此需要在两者间设置绝缘层进行隔离。作为选择，本实施例中，第二金属层 200与第一金属层 100和第三金属层之间设有绝缘层 300; 第二金属层 200和第一金属层 100之间的绝缘层部分设有通孔 301，第二金属层 200可填充至通孔 301内，通过通孔 301连接第一金属层 100。第二金属层 200和第三金属层之间则通过绝缘层 300实现相绝缘。 [0027] Specifically, since the second metal layer 200-end of the second signal line 412 extends to connect the E0A driving circuit 40 and cross the third metal layer of the gate scanning line signal line 31, it is necessary to provide insulation between the two. The layers are isolated. Optionally, in this embodiment, an insulating layer 300 is disposed between the second metal layer 200 and the first metal layer 100 and the third metal layer; and an insulating layer portion between the second metal layer 200 and the first metal layer 100 is disposed. There is a through hole 301, and the second metal layer 200 can be filled into the through hole 301, and the first metal layer 100 is connected through the through hole 301. Phase insulation is achieved between the second metal layer 200 and the third metal layer by the insulating layer 300.

[0028] 绝缘层 300可采用氮化硅、氧化硅等绝缘材料制成。 [0028] The insulating layer 300 may be made of an insulating material such as silicon nitride or silicon oxide.

[0029] 此外，在多组自上至下依次排列的像素组 50中，位于下方的像素组 50的第二信号线 412的一端需要向上延伸，跨过位于上方的像素组 50的发光扫描信号线 41直至连接 EOA驱动电路 40，绝缘层 300分布在不同像素组 50对应的发光扫描信号线 41之间，将位于下方的像素组 50的第二信号线 412与位于上方的像素组 50的发光扫描信号线 41相隔幵，实现了像素组 50之间的发光扫描信号线 41相绝缘。 [0029] Furthermore, in the plurality of sets of pixel groups 50 arranged in order from top to bottom, one end of the second signal line 412 of the pixel group 50 located below needs to extend upward, across the illuminating scan signal of the pixel group 50 located above. The line 41 is connected to the EOA driving circuit 40, and the insulating layer 300 is distributed between the corresponding scanning signal lines 41 of the different pixel groups 50, and the second signal line 412 of the pixel group 50 located below and the pixel group 50 located above The scanning signal lines 41 are spaced apart to realize the insulation of the light-emitting scanning signal lines 41 between the pixel groups 50.

[0030] 本发明的显示屏，包括上述的显示面板。在显示屏中，通过显示面板实现了显示屏的窄边框设计，整体上还可提高显示屏中显示区的占比。 [0030] The display screen of the present invention includes the above display panel. In the display, the narrow bezel design of the display panel is realized by the display panel, and the proportion of the display area in the display can be improved as a whole.
