Due to their superior characteristics, including self-emissive organic light-emitting diodes, no need for a backlight, high contrast, thinness, wide viewing angle, fast response speed, applicability to flexible panels, wide operating temperature range, and simpler construction and manufacturing processes, they are considered the next generation of emerging flat panel display technologies.

[0003] However, in existing OLED displays, the voltage drop between the portion of the cathode layer near the bonding region and the portion far from the bonding region is too large, resulting in uneven display. Summary of the Invention

[0006] A cathode layer extending from the display area to the non-display area;

[0008] The overlapping metal includes a metal segment extending along the bonding area toward the display area, and the metal segment is provided with at least one gap; wherein the gap is located on the side of the overlapping area away from the display area.

[0009] Optionally, the metal segment includes a first end close to the bonding area and a second end away from the bonding area;

[0010] The metal segment includes a slit that extends from a first end of the metal segment to a second end of the metal segment.

[0018] Optionally, along the arrangement direction of the first metal segment and the display area, the width ratio of the portion of the first metal segment located on one side of the first gap to the portion of the first metal segment located on the other side of the first gap ranges from 0.2 to 5; and / or,

[0019] The width ratio of the portion of the second metal segment located on one side of the second gap to the portion of the second metal segment located on the other side of the second gap ranges from 0.2 to 5.

[0020] Optionally, along the arrangement direction of the first metal segment and the display area, the portion of the first metal segment located on one side of the first gap and the portion of the first metal segment located on the other side of the first gap are disposed in the same layer or in different layers; and / or,

[0021] The portion of the second metal segment located on one side of the second gap is disposed in the same layer or in a different layer from the portion of the second metal segment located on the other side of the second gap.

Furthermore, the technical solution of this application directly creates gaps in the metal segment of the overlapping metal, eliminating the need to widen the bezel. This reduces the voltage drop between the first end of the bonding area and the second end away from the bonding area on the cathode layer metal segment without increasing the width of the metal segment, thereby reducing losses and improving display uniformity.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0035] As mentioned in the background section, existing display panels suffer from excessive voltage drop between the portion of the cathode layer near the bonding area and the portion far from the bonding area, leading to uneven display. After careful research, the applicant discovered that the cause of this technical problem is: existing display panels are bonded to the cathode layer via a bonding metal, which extends to the bonding area of ​​the display panel to bond with the driver chip. This allows the driver chip to transmit the power signal required by the cathode layer to the cathode layer. However, the excessive resistance of the bonding metal results in an excessive voltage drop between the portion of the bonding metal near the bonding area and the portion far from the bonding area, which in turn leads to an excessive voltage drop between the portion of the cathode layer near the bonding area and the portion far from the bonding area, causing uneven display in the display panel.

[0036] To address the aforementioned technical problems, the present invention proposes the following solutions:

[0037] This embodiment provides a display panel. Figure 1 This is a schematic diagram of a display panel provided in an embodiment of the present invention. Figure 2 This is a cross-sectional view along the A1A2 direction of a display panel provided in an embodiment of the present invention. See also... Figure 1 and Figure 2 The display panel 100 has a display area 110 and a non-display area 120. The non-display area 120 includes a bonding area 121. The display panel 100 includes: a cathode layer 130 extending from the display area 110 to the non-display area 120; and an overlapping metal 140 located in the non-display area 120 and overlapping with the cathode layer 130 in the overlapping area. The overlapping metal 140 includes a metal segment 141 extending along the bonding area 121 toward the display area 110, and at least one gap 142 is provided on the metal segment 141. The gap 142 is located on the side of the overlapping area away from the display area.

[0038] The display area 110 is used to display the image, and the non-display area 120 includes a bonding area 121, which is used to connect a driver chip. The driver chip provides the voltage signal required by the cathode layer 130 to the bonding metal 140. The cathode layer 130 can be a single layer and extends from the display area 110 to the non-display area 120. The bonding metal 140 overlaps with the cathode layer 130 at the bonding area. The bonding area refers to the area where the bonding metal 140 and the cathode layer 130 overlap, and the bonding area is the area on the bonding metal 140. The bonding area only covers a portion of the bonding metal 140 near the cathode layer 130, and the bonding area cannot completely cover the bonding metal 140. The bonding metal 140 includes a metal segment 141 extending along the bonding area 121 toward the display area 110. At least one gap 142 is provided on the metal segment 141, located on the side of the bonding area away from the display area, i.e., outside the bonding area. The cathode layer 130 can extend to the gap 142. For example, if the metal segment 141 has a gap 142, the gap 142 divides the metal segment 141 into two segments: a first segment closer to the display area and a second segment farther from the display area. The second segment is outside the bonding area, and the cathode layer 130 cannot extend to the second segment. Assuming that before the gap 142 is provided, the resistance of the metal segment 141 is R, the current flowing through the metal segment 141 is I, and the current direction is from the second end B of the metal segment 141 to the first end A of the metal segment 141, then the voltage drop from the first end A to the second end B of the metal segment 141 is RI. In this design, the first end A of the metal segment 141 is the end closest to the bonding area 121, and the second end B of the metal segment 141 is the end opposite to the first end A and away from the bonding area. The direction of the gap 142 can be, for example, along the first end A to the second end B, or other directions, and is not limited here. After setting the gap 142, the metal segment 141 is divided into a first segment close to the display area 110 and a second segment away from the display area 110. The first segment is connected to the cathode layer, and the second segment is not connected to the cathode layer. The worst voltage drop point is located on the first segment of the metal segment 141. The current on the metal segment 141 becomes the pixel current located below the worst voltage drop point, which passes through the first segment below the worst voltage drop point and goes directly down to the first end A of the metal segment 141. The pixel current located above the worst voltage drop point first passes through the first segment at the worst voltage drop point and goes up to the second end B of the metal segment 141, and then from the second end B of the metal segment 141, it passes through the second segment and goes down to the first end A of the metal segment 141. By setting the parameters of gap 142, the worst voltage drop point is changed from the second terminal B in the prior art to a point between the first terminal A and the second terminal B, located on the first segment of metal segment 141. For example, by setting the position and size of the gap so that the distance from the worst voltage drop point C to the first terminal A is two-thirds of the distance of the first segment of metal segment 141, the resistance R1 from point C of the first segment of metal segment 141 to the first terminal A is... The sum of the resistances R2 from point C of the first segment of metal segment 141 to the second end B, and then from the second end B of the second segment of metal segment 141 to the first end A, is: Two-thirds of the current in metal segment 141 flows directly from point C (where the voltage drop is worst) to terminal A of metal segment 141. The remaining one-third of the current flows from point C of the first segment of metal segment 141 to terminal B, and then from terminal B back to terminal A of the second segment of metal segment 141. Therefore, the voltage drop from point C to terminal A of the first segment of metal segment 141 is... The voltage drop from point C of the first segment of metal segment 141 to the second end B, and then from the second end B of the second segment of metal segment 141 back to the first end A of metal segment 141, is also... Therefore, after setting the gap 142, the voltage drop at the second end B of the metal segment 141 is approximately 90% of the original value. Thus, by setting the gap 142, the voltage drop can be reduced, achieving the effect of reducing power consumption. Furthermore, the technical solution of this embodiment can directly create the gap in the metal segment of the overlapping metal without widening the frame, thereby reducing the voltage drop between the first end of the bonding area and the second end away from the bonding area on the cathode layer metal segment without increasing the width of the metal segment.

[0039] The technical solution of this embodiment solves the problem of excessive voltage drop between the portion of the cathode layer near the bonding area and the portion far from the bonding area by creating a gap in the metal segment that overlaps with the cathode layer. This reduces the voltage drop between the second end of the metal segment away from the bonding area and the first end of the metal segment near the bonding area, thus improving the display panel's unevenness and reducing power consumption. Furthermore, this technical solution allows for direct creation of the gap within the metal segment of the overlapping metal, eliminating the need to widen the bezel. This reduces the voltage drop between the first end of the bonding area and the second end far from the bonding area on the cathode layer metal segment without increasing the width of the metal segment, thereby reducing losses and improving display uniformity.

[0040] Optionally, Figure 3 This is a schematic diagram of another display panel provided in an embodiment of the present invention. See also: Figure 3 The metal segment 141 includes a first end A near the binding area 121 and a second end B away from the binding area; the metal segment 141 includes a gap 142 extending from the first end A of the metal segment 141 to the second end B of the metal segment 141.

[0041] Specifically, by extending the gap 142 from the first end A of the metal segment 141 to the second end B of the metal segment 141, the gap 142 is easier to implement in terms of manufacturing process, and the uniformity of current distribution on the metal segment 141 is ensured, which can better improve the problem of uneven display on the display panel.

[0042] For example, see Figure 3 The display area 110 includes a first display area 111 and a second display area 112, the second display area 112 being a transparent display area; wherein, the second display area 112 is located at the end of the display area away from the binding area 121.

[0043] Specifically, the second display area 112 can be, for example, an under-display camera (UDC) area. Since the second display area 112 is transparent and the underlying layer is non-reflective, it requires higher brightness. Therefore, the second display area 112 needs a larger single-point current. When a gap 142 is provided in the metal segment 141, the voltage drop at the second end B of the metal segment 141, which is farther from the bonding area 121, is smaller than that at the first end A of the bonding area 121. This allows the second display area 112 to obtain a higher single-point current, improving the display effect.

[0044] Optionally, see Figure 3 The metal segment 141 includes a first metal segment 141a and a second metal segment 141b located on both sides of the display area 110, respectively; at least one gap 142 includes a first gap 142a and a second gap 142b located on the first metal segment 141a and the second metal segment 141b, respectively.

[0045] For details, see Figure 3 , Figure 3 The X and Y directions are defined. The X direction is, for example, the arrangement direction of the first metal segment 141a and the display area 110, and the Y direction is, for example, the direction from the bonding area to the display area. The X and Y directions are perpendicular. Because there are overlapping metals on both sides of the display area 110, the metal segment 141 includes a first metal segment 141a and a second metal segment 141b located on both sides of the display area 110. A first gap 142a is provided on the first metal segment 141a, and a second gap 142b is provided on the second metal segment 141b. This makes the voltage drop at the second end B of the first metal segment 141a and the second metal segment 141b away from the bonding area 121 lower than the voltage drop at the first end A of the metal segment 141b near the bonding area 121. This makes the voltage and current of the metal segments on both sides of the display area 110 that are on the same straight line in the X direction consistent or closer, making the pixel display in the same row more uniform, reducing power consumption, and improving the problem of uneven display on the display panel.

[0046] Optionally, see Figure 3 The first slit 142a and the second slit 142b are symmetrical about the center line 170 of the display area 110.

[0047] Specifically, the first metal segment 141a and the second metal segment 141b are symmetrical about the center line 170 of the display area 110, and the first gap 142a and the second gap 142b are symmetrical about the center line 170 of the display area 110, so that the voltage and current of the metal segments on both sides of the display area 110 are consistent or closer in the X direction, thus ensuring the uniformity of the display in the display area 110.

[0048] For example, see Figure 3 There are multiple first gaps 142a and second gaps 142b; the first gaps 142a are evenly distributed on the first metal segment 141a; the second gaps 142b are evenly distributed on the second metal segment 142b.

[0049] For example, multiple first gaps 142a are uniformly distributed on the first metal segment 141a, and can be vertically distributed, horizontally distributed, or distributed in other ways; multiple second gaps 142b are uniformly distributed on the second metal segment 141b, and can be vertically distributed, horizontally distributed, or distributed in other ways. The number of second gaps 142b can be the same as the number of first gaps 142a, or different, and the distribution of the multiple second gaps 142b on the second metal segment 141b can be the same as or different from the distribution of the multiple first gaps 142a on the first metal segment 141a. For example, see [link to example]. Figure 4 , Figure 4 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Three first gaps 142a are evenly distributed on the first metal segment 141a, and three second gaps 142b are evenly distributed on the second metal segment 141b. Other distribution configurations are also possible in other embodiments, for example... Figure 5 , Figure 5 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Three first gaps 142a with a certain angle are evenly distributed on the first metal segment 141a, and three second gaps 142b are evenly distributed on the second metal segment 141b. In summary, the shape, number, and distribution pattern of the plurality of first gaps 142a and the plurality of second gaps 142b can be various, and no specific limitation is made here.

[0050] Optionally, see Figure 3 Along the arrangement direction of the first metal segment 141a and the display area 110, the width ratio of the portion of the first metal segment 141a located on one side of the first gap 142a to the portion of the first metal segment 141a located on the other side of the first gap 142a ranges from 0.2 to 5; and / or, the width ratio of the portion of the second metal segment 141b located on one side of the second gap 142b to the portion of the second metal segment 141b located on the other side of the second gap 142b ranges from 0.2 to 5.

[0051] Specifically, along the arrangement direction of the first metal segment 141a and the display area 110, i.e. along the X direction, the first gap 142a divides the first metal segment 141a into two parts. The two parts are located on both sides of the first gap 142a. The width ratio between the part on one side of the first gap 142a (which can be understood as the first segment of the first metal segment 141a) and the part on the other side of the first gap 142a (which can be understood as the second segment of the first metal segment 141a) is in the range of 0.2 to 5. The second slit 142b divides the second metal segment 141b into two parts, which are located on both sides of the second slit 142b. The width ratio of the part on one side of the second slit 142b (which can be understood as the first segment of the second metal segment 141b) to the part on the other side of the second slit 142b (which can be understood as the second segment of the second metal segment 141b) is in the range of 0.2 to 5. This is easier to achieve in terms of manufacturing process. By controlling the width ratio of the parts on both sides of the slit, it is possible to avoid the manufacturing process being difficult due to the metal segment on one side being too small. This makes it easier to manufacture the first slit 142a and the second slit 142b, and it also prevents the current from being unable to flow due to the excessive resistance caused by the metal segment on one side being too small.

[0052] Optionally, Figure 6 This is a schematic diagram of another display panel provided in an embodiment of the present invention, see below. Figure 2 and Figure 6 Along the arrangement direction of the first metal segment 141a and the display area 110, the portion of the first metal segment 141a located on one side of the first gap 142a and the portion of the first metal segment 141a located on the other side of the first gap 142a are disposed in the same layer or in different layers; and / or, the portion of the second metal segment 141b located on one side of the second gap 142b and the portion of the second metal segment 141b located on the other side of the second gap 142b are disposed in the same layer or in different layers.

[0053] For details, see Figure 2 Along the arrangement direction of the first metal segment 141a and the display area 110, the first segment and the second segment can be arranged on the same layer. In this case, the portion located on one side of the first gap 142a and the portion of the first metal segment 141a located on the other side of the first gap 142a belong to the same metal layer. This co-layer arrangement can reduce manufacturing processes, lower costs, and facilitate wiring and connection. Furthermore, the co-layer arrangement results in a smaller voltage drop. See also... Figure 6Along the arrangement direction of the first metal segment 141a and the display area 110, the portion of the first metal segment 141a located on one side of the first gap 142a and the portion of the first metal segment 141a located on the other side of the first gap 142a can be configured as separate layers. In this case, the portion located on one side of the first gap 142a and the portion of the first metal segment 141a located on the other side of the first gap 142a do not belong to the same metal layer. The two metal layers can be connected through vias. This separate layer configuration can also reduce voltage drop and improve the problem of uneven display. See also Figure 2 Along the arrangement direction of the second metal segment 141b and the display area 110, the portion of the second metal segment 141b located on one side of the second gap 142b and the portion of the second metal segment 141b located on the other side of the second gap 142b can be arranged in the same layer. In this case, the portion located on one side of the second gap 142b and the portion of the second metal segment 141b located on the other side of the second gap 142b belong to the same metal layer. This same-layer arrangement can reduce the manufacturing process, decrease costs, and facilitate wiring and connection. Furthermore, the same-layer arrangement results in a smaller voltage drop. See also... Figure 6 Along the arrangement direction of the second metal segment 141b and the display area 110, the portion of the second metal segment 141b located on one side of the second gap 142b and the portion of the second metal segment 141b located on the other side of the second gap 142b can be set in different layers. In this case, the portion located on one side of the second gap 142b and the portion of the second metal segment 141b located on the other side of the second gap 142b do not belong to the same metal layer. The two metal layers can be connected through vias. Setting in different layers can also reduce voltage drop and improve the problem of uneven display.

[0054] Optionally, see Figure 6 Along the thickness direction of the display panel 100, the display panel 100 includes a first metal layer 150 near the cathode layer 130 and a second metal layer 160 away from the cathode layer 130; along the arrangement direction of the first metal segment 141a and the display area 110, the portion of the first metal segment 141a located on the side of the first gap 142a near the display area 110 is disposed in the same layer as the first metal layer 150 and overlaps with the cathode layer 130, and the portion of the first metal segment 141a located on the side of the first gap 142a away from the display area 110 is disposed in the same layer as the second metal layer 160; and / or, along the arrangement direction of the first metal segment 141a and the display area 110, the portion of the second metal segment 141b located on the side of the second gap 142b near the display area 110 is disposed in the same layer as the first metal layer 150 and overlaps with the cathode layer 130, and the portion of the second metal segment 141b located on the side of the second gap 142b away from the display area 110 is disposed in the same layer as the second metal layer 160.

[0055] Specifically, the portion of the first metal segment 141a located on the side of the first gap 142a near the display area 110 is co-layered with the first metal layer 150 and overlaps with the cathode layer 130. The portion of the first metal segment 141a located on the side of the first gap 142a away from the display area 110 is co-layered with the second metal layer 160. The first metal layer 150 and the second metal layer 160 are connected through vias. Thus, the portions on both sides of the first gap 142a are arranged in different layers, which can also reduce the voltage drop of the second end B on the metal segment away from the bonding area 121 relative to the first end A near the bonding area 121. The portion of the second metal segment 141b located on the side of the second gap 142b near the display area 110 is co-layered with the first metal layer 150 and overlaps with the cathode layer 130. The portion of the second metal segment 141b located on the side of the second gap 142b away from the display area 110 is co-layered with the second metal layer 160. The first metal layer 150 and the second metal layer 160 are connected through vias.

[0056] The technical solution of this embodiment solves the problem of excessive voltage drop between the first end near the bonding area and the second end far from the bonding area on the metal segments of the cathode layer metal segments on both sides of the display area by setting gaps in the metal segments that overlap with the cathode layer. This reduces the voltage drop between the first end near the bonding area and the second end far from the bonding area on the metal segments of the cathode layer, thus improving the problem of uneven display on the display panel and reducing power consumption. Furthermore, the technical solution of this application directly creates gaps in the existing metal segments without widening the bezel, thereby reducing the voltage drop between the portion of the cathode layer near the bonding area and the portion far from the bonding area without increasing the width of the metal segments.
