[0029] As can be seen from the background technology, the display panel in the prior art has the problem of floating wiring. Now, the causes of the structural problem of the display panel are analyzed in combination with a display panel:

[0030] Figure 1 is a schematic diagram of a cross-sectional structure of a display panel in the prior art; Figure 2 This is a partial enlarged view of a display panel in the prior art.

[0031] Please refer to Figure 1 and Figure 2, the structure of the display panel includes:

[0032] A substrate, the substrate comprising: a display area 100, the display area 100 comprising a central portion I and an edge portion II, the edge portion II being located on both sides of the central portion I along a first direction X, the first direction X being parallel to a surface of the substrate;

[0033] A driving array, located on one side of the substrate;

[0034] A light emitting device, located on a side of the driving array away from the substrate;

[0035] The driving array comprises: an outer ring signal line 101, the outer ring signal line 101 is located at one side of the substrate, and the outer ring signal line 101 surrounds the display area 100;

[0036] The power signal line 102 extends along a second direction Y, and the power signal line 102 includes an edge signal line 103, and the edge signal line 103 is located at a position corresponding to the edge portion II. The second direction Y intersects with the first direction X, and the second direction Y is parallel to the surface of the substrate.

[0037] Specifically, the second direction Y is perpendicular to the first direction X.

[0038] The power signal line 102 also includes: a central signal line 104 and an incoming line segment 105, the central signal line 104 is located at a corresponding position of the central portion I, and one end of the central signal line 104 is electrically connected to the outer ring signal line 101 through the incoming line segment 105.

[0039] The inlet wire segment 105 is divided into a first inlet wire 106 and a second inlet wire 107, wherein the first inlet wire 106 is the first inlet wire segment close to the central axis of the central portion I along the first direction X, and the second inlet wire 107 is the remaining inlet wire segments except the first inlet wire 106. Specifically, in the prior art, the size of the first inlet wire 106 in the first direction X is 30 μm. There is no fixed specification for the number of the second inlet wires 107 and the size of the second inlet wires 107 in the first direction X.

[0040] In this embodiment, the edge signal line 103 extends along the second direction Y, and each edge signal line 103 has a first end and a second end along the second direction Y. Both ends of each edge signal line 103 are not fixedly connected to any circuit, which will cause the edge signal line 103 corresponding to the edge portion II of the display area 100 to be "floating". An effective solution is to short-circuit the edge signal line 103 corresponding to the edge portion II through a short-circuit wire, but a simple short-circuit will result in an excessively large current density of the short-circuit wire, which will cause a display panel burn problem in actual applications.

[0041] In addition, it is known from simulation experiments that when the size of the first inlet line 106 in the first direction X is 30 μm, the current density at the first inlet line 106 is approximately 5.85E+08 A / m 2 , the risk of burns is extremely high.

[0042] To solve the technical problem, the present invention provides a display panel, comprising: a substrate, the substrate comprising: a display area, the display area comprising a central portion and an edge portion, the edge portion being located on both sides of the central portion along a first direction, the first direction being parallel to the surface where the substrate is located; a driving array being located on one side of the substrate; a light-emitting device being located on a side of the driving array away from the substrate; the driving array comprising: an outer ring signal line, the outer ring signal line being located on one side of the substrate, the outer ring signal line surrounding the display area; a power signal line, the power signal line extending along a second direction, the power signal line comprising: an edge signal line, the edge signal line being located at a position corresponding to the edge portion, the second direction intersecting with the first direction, and the second direction being parallel to the surface where the substrate is located; a short-circuit wire, the short-circuit wire electrically connecting one end of the edge signal line and the outer ring signal line.

[0043] In the display panel of the technical solution of the present invention, the edge signal line is connected to the outer circle signal line through a short-circuit wire, which improves the suspension problem caused by the inability to fix the two ends of the edge signal line at the edge; and the light-emitting device is located on the side of the driving array away from the substrate, the power signal line is connected in parallel with the light-emitting device, and the value of the parallel resistance of the power signal line and the light-emitting device is smaller than the value of the resistance of the light-emitting device. The parallel mode of the power signal line and the light-emitting device reduces the voltage drop of the light-emitting device, thereby improving the brightness uniformity of the display panel; in addition, the cross-sectional area of ​​the first incoming line is large. When the current passing through the display panel is constant, the current density of the first incoming line is small, which solves the problem of a high risk of burns at the position of the first incoming line due to excessive current density of the first incoming line, and optimizes the structure of the display panel.

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0045] Figure 3 is a schematic top view of the structure of a display panel according to an embodiment of the present invention; Figure 4 yes Figure 3 A schematic cross-sectional structure diagram of a display panel at position AA1; Figure 5 yes Figure 3 Please refer to the enlarged view of the part. Figure 3 and Figure 4The structure of the display panel includes: a substrate, the substrate includes: a display area 200, the display area 200 includes a central portion I and an edge portion II, the edge portion II is located on both sides of the central portion I along a first direction X, and the first direction X is parallel to the surface where the substrate is located.

[0046] The display panel has an axisymmetric structure, the axis of symmetry of the display panel is perpendicular to the first direction X, and the axis of symmetry of the display panel is parallel to the surface where the substrate is located. Specifically, in some embodiments of the present invention, the structures of the two edge portions II of the display panel are completely identical.

[0047] The display area 200 has pixel units arranged in an array.

[0048] Specifically, in some embodiments of the present invention, the resolution of the display panel is 1200×2560. In other embodiments, the resolution of the display panel may also be other values.

[0049] Please refer to Figure 3 and Figure 4 The structure of the display panel includes: a driving array 201, located on one side of the substrate.

[0050] The driving array 201 includes an outer ring signal line 202 . The outer ring signal line 202 is located on one side of the substrate, and the outer ring signal line 202 surrounds the display area 200 .

[0051] The function of the outer ring signal line 202 is to provide a negative power signal to the pixel units on the display area 200 and provide light-emitting energy.

[0052] The structure of the display panel may include, for example, a substrate, an M0 layer located on the substrate, a semiconductor layer located on the M0 layer, an M1 layer located on the semiconductor layer, an MC layer located on the M1 layer, an M2 layer located on the MC layer, an M3 layer located on the M2 layer, and a light-emitting device located on the M3 layer. The light-emitting device includes an anode layer, a light-emitting material layer located on the anode layer, and a cathode layer located on the light-emitting material layer. Specifically, in some embodiments of the present invention, the outer ring signal line 202 is located in the M2 layer.

[0053] Please refer to Figure 3 and Figure 4The driving array 201 includes: a power signal line 203, the power signal line 203 extends along a second direction Y, the power signal line 203 includes: an edge signal line 204, the edge signal line 204 is located at a corresponding position of the edge portion II, the second direction Y intersects with the first direction X, and the second direction Y is parallel to the surface where the substrate is located.

[0054] The function of the power signal line 203 is that the power signal line 203 is connected to each pixel unit to control the pixel unit to be turned on or off.

[0055] The second direction Y intersects the first direction X, and the second direction Y and the first direction X are both parallel to the surface of the substrate. That is, the first direction X is not parallel to the second direction Y. Specifically, in some embodiments of the present invention, the second direction Y is perpendicular to the first direction X. In other embodiments, the angle between the first direction and the second direction may also be other angles.

[0056] Specifically, in some embodiments of the present invention, the power signal line 203 is located in the M2 layer.

[0057] Please refer to Figure 3 and Figure 4 , the edge signal line 204 is located at a position corresponding to the edge portion II, that is, the projection of the edge signal line 204 on the substrate surface is within the projection range of the edge portion II on the substrate surface.

[0058] The edge signal line 204 is connected to each pixel unit on the edge portion II to control the on or off of the pixel unit.

[0059] Please refer to Figure 5 Specifically, in this embodiment, along the first direction X from one side to the other side, the edge signal lines 204 are sequentially the first edge signal line, the second edge signal line, ... the nth edge signal line, the n+1th edge signal line, the n+2th edge signal line, ... the 2nth edge signal line, where n is a positive integer and n is greater than or equal to 20. The structure of the display panel is an axisymmetric structure, that is, each edge portion II has n edge signal lines, where n is a positive integer and n is greater than or equal to 20.

[0060] For details, please refer to Figure 5In some embodiments of the present invention, in a 2×4 pixel unit, the edge signal line 204 vertically runs through one column, that is, one edge signal line 204 connects the 2×4 pixel units located on the display area 200. In other embodiments, it also includes: in a 2×4 pixel unit, the edge signal line vertically runs through two columns, that is, two edge signal lines connect the 2×4 pixel units located on the display area 200. In a 2×4 pixel unit, the edge signal line 204 vertically runs through one column, which saves more layout space than the edge signal line 204 vertically runs through two columns.

[0061] Please refer to Figure 3 and Figure 5 The power signal line 203 also includes: a center signal line 205 and an incoming line segment 206, the center signal line 205 is located at a corresponding position of the center portion I, and one end of the center signal line 205 is electrically connected to the outer ring signal line 202 through the incoming line segment 206.

[0062] The central signal line 205 is connected to each pixel unit on the central portion I to control the on or off of the pixel unit.

[0063] The central signal line 205 is located at a position corresponding to the central portion I, that is, the projection of the central signal line 205 on the substrate surface is located within the projection range of the central portion I on the substrate surface.

[0064] The inlet segment 206 connects the central signal line 205 and the outer ring signal line 202, so that the negative power supply signal provided by the outer ring signal line 203 is transmitted to the central signal line 205 through the inlet segment 206, thereby controlling the opening or closing of each pixel unit.

[0065] The inlet line segment 206 is divided into a first inlet line 207 and a second inlet line 208. The first inlet line 207 is the first inlet line segment 206 close to the central axis 209 of the center portion I along the first direction X, and the second inlet line 208 is the remaining inlet line segments 206 except the first inlet line 207. The size of the first inlet line 207 along the first direction X is greater than the size of the second inlet line 208 along the first direction X.

[0066] For details, please refer to Figure 5 The central axis 209 is: a symmetry axis of the display panel extending along the second direction Y. The display panel is symmetrically distributed with the central axis 209 as the symmetry axis.

[0067] Please refer to Figure 5 , the size of the inlet line segment 206 along the first direction X is greater than 15 μm. That is, the size of the first inlet line 207 along the first direction X and the size of the second inlet line 208 along the first direction X are both greater than 15 μm.

[0068] Specifically, in some embodiments of the present invention, the size of the first inlet line 207 along the first direction X is greater than 100 μm. The diameter of the first inlet line 207 is greater than 100 μm. The larger diameter of the first inlet line 207 makes the cross-sectional area S of the first inlet line 207 larger. When the current transmitted to the power signal line 203 through the outer ring signal line 202 is constant, the cross-sectional area of ​​the first inlet line 207 is larger, which reduces the current density at the first inlet line 207 and reduces the risk of burns at the first inlet line 207.

[0069] For example, according to simulation experiments, when the size of the first inlet line 207 in the first direction X is 30 μm, the current density at the first inlet line 207 is about 5.85E+08 A / m 2 , the risk of burns is extremely high at the location of the first inlet line 207;

[0070] When the dimension of the first inlet line 207 in the first direction X is 90 μm, the current density at the first inlet line 207 is about 3.17E+08 A / m 2 , the risk of burns is reduced at the location of the first inlet line 207;

[0071] When the dimension of the first inlet line 207 in the first direction X is 100 μm, the current density at the first inlet line 207 is approximately 1.99E+08 A / m 2 There is basically no risk of burns at the location of the first inlet line 207.

[0072] In some embodiments of the present invention, the number of the second incoming lines 208 is greater than or equal to 60.

[0073] For example, through simulation experiments, it can be known that when the number of second inlet wires 208 is 73 and the size of each second inlet wire 208 along the first direction X is greater than 15 μm, the current density of the second inlet wire 208 is up to 3.28e+08 A / m 2 , the threshold of current density is 4.0E+08A / m 2， (That is, when the current density of the second incoming line 208 exceeds this threshold, the screen of the display panel will be burned). According to the proportional relationship, we can get

[0074] The number of second incoming wires 208 = (3.28E+08)*73 / (4.0E+08)≈60. That is, the number of second incoming wires 208 must be at least greater than 60 to ensure that the current density of the second incoming wires 208 does not exceed the current density threshold, so that the screen of the display panel is not burned.

[0075] In other embodiments, the current magnitude of the actual simulation experiment is used as a calculation standard to obtain the number of second incoming lines.

[0076] Please refer to Figure 3 and Figure 5 The driving array 201 includes a short-circuit wire 210 , and the short-circuit wire 210 is electrically connected to one end of the edge signal line 204 and the outer ring signal line 202 .

[0077] Specifically, in some embodiments of the present invention, the short-circuit wire 210 enables the negative power supply signal provided by the outer ring signal line 202 to be transmitted to the edge signal line 204 through the short-circuit wire 210 .

[0078] Specifically, in some embodiments of the present invention, the short-circuit line 210 is located in the M2 layer.

[0079] In some embodiments of the present invention, the outer ring signal line 202, the power signal line 203 and the short-circuit line 210 are all located in the same layer. Specifically, in some embodiments of the present invention, the outer ring signal line 202, the power signal line 203 and the short-circuit line 210 are all located in the M2 layer.

[0080] Please refer to Figure 3 The short-circuit wire 210 electrically connects one end of the edge signal line 204 and the outer ring signal line 202 , so that the edge signal line 204 is fixedly connected to the short-circuit wire 210 to prevent the edge signal line 204 from floating.

[0081] Please refer to Figure 3 , both ends of the edge signal line 204 are electrically connected to the outer ring signal line 202 through a short-circuit line 210. That is, along the second direction Y, the edge signal line 204 has a first end and a second end opposite to each other, the first end of the edge signal line 204 is connected to a short-circuit line 210, and the second end of the edge signal line 204 is connected to another short-circuit line 210. Both ends of the edge signal line 204 are fixedly connected to the short-circuit line 210 to prevent the edge signal line 204 from floating.

[0082] Please refer to Figure 3 and Figure 5 , one end of the plurality of edge signal lines 204 is electrically connected to the outer ring signal line 202 through the same short-circuit line 210. That is, the first end of the first edge signal line 204, the first end of the second edge signal line 204, ... the first end of the nth edge signal line 204 are electrically connected through the same short-circuit line 210, so that the plurality of edge signal lines 204 are fixed to prevent the edge signal lines 204 from floating.

[0083] For details, please refer to Figure 5In some embodiments of the present invention, the size of the short-circuit wire 210 connected to the first edge signal line 204, the second edge signal line 204, ... the nth edge signal line 204, and the n+1th edge signal line 204, the n+2th edge signal line 204, ... the 2nth edge signal line 204 along the second direction Y is greater than or equal to 14 μm. The size of the short-circuit wire 210 along the second direction Y is large, so that the current density at the location of the short-circuit wire 210 is reduced, thereby reducing the risk of burns at the location of the short-circuit wire 210.

[0084] Please refer to Figure 3 and 5 , the structure of the display panel includes: a central connecting line 211.

Figure 5 As shown), the central connecting line 211 extends along the first direction X, and the central signal line 205 and the incoming line segment 206 are both electrically connected to the central connecting line 211.

[0086] Please refer to Figure 3 The structure of the display panel includes: an extended short-circuit line 212 , and the extended short-circuit line 212 is electrically connected to the short-circuit lines 210 at both ends of an edge signal line 204 .

[0087] The extended short-circuit wire 212 is used to fix the two short-circuit wires 210 at both ends of any edge signal line 204, so that the two short-circuit wires 210 at both ends of any edge signal line 204 are electrically connected through the extended short-circuit wire 212 to prevent the short-circuit wire 210 from floating; and the extended short-circuit wire 212 reduces the current density of the display panel.

[0088] In a plane parallel to the substrate surface, the extended short-circuit wire 212 is located between the edge portion II and the outer ring signal line 202 along the first direction X.
