Abstract
Description
Technical Field
[0001] This invention relates to the field of display technology, and more particularly to a display panel and a display terminal. Background Technology
[0002] Active-matrix organic light-emitting diode (AMOLED) display panels are gradually becoming the next-generation display technology due to their high contrast, wide color gamut, and low power consumption. Compared with traditional LCD panels, AMOLED display panels are easier to make flexible, making them a key technology for wearable and foldable products. With the continuous development of display technology, narrow bezel technology has become a differentiating factor to attract users. Existing technologies achieve narrow bezels by compressing the linewidth of the fan-out area's traces.
[0003] In the fabrication process, a large area of metal needs to be etched away from the periphery of the fan-out region. The etchant concentration is higher at the periphery, posing a risk of breakage to the fan-out traces near the periphery. While ensuring the linewidth of the densely packed fan-out traces is within the process safety margin, due to the loading effect, the actual linewidth of the fan-out traces at the corners and angles is thinner than that of the inner densely packed trace areas, posing a risk of breakage. Therefore, it is necessary to improve this defect. Summary of the Invention
[0004] This invention provides a display panel to address the technical problem in existing display panels where the fan-out traces are actually thinner at the corners and diagonal lines, posing a risk of breakage.
[0005] This invention provides a display panel including a display area and a fan-out area located on one side of the display area. The fan-out area includes multiple fan-out traces that are insulated from each other. Each fan-out trace includes a straight section and an inclined section. The inclined section is electrically connected to the end of the straight section away from the display area, and the inclined section and the straight section are set at an obtuse angle. The display panel also includes multiple protective components, each of which corresponds one-to-one with the inclined section of the multiple fan-out traces. Each protective component is located close to the corresponding inclined section. The orthographic projection of each protective component on the plane where the fan-out trace is located is located in the area between two adjacent straight sections, and the angle between the protective component and the straight section is greater than 0 degrees and less than 180 degrees.
[0006] In the display panel provided in this embodiment of the invention, the tilted segment includes a first line segment and a second line segment. A first end of the first line segment is electrically connected to an end of the straight segment away from the display area, and a second end of the first line segment is electrically connected to the second line segment. The first line segment is located in the region between the straight segment electrically connected to the first line segment and an adjacent straight segment. Each of the protective members includes a widening portion. A first end of the widening portion is electrically connected to the straight segment, and a second end of the widening portion is electrically connected to the second line segment.
[0007] In the display panel provided in the embodiment of the present invention, the widened portion is fitted to the first line segment.
[0008] In the display panel provided in the embodiment of the present invention, the widening portion is disposed on the same layer as the first line segment, and the widening portion is located on the side of the first line segment closer to the display area.
[0009] In the display panel provided in the embodiments of the present invention, in the extension direction perpendicular to the inclined segment, the sum of the width of the first line segment and the width of the widened portion is greater than or equal to the width of the second line segment.
[0010] In the display panel provided in the embodiments of the present invention, in the extension direction perpendicular to the inclined segment, the sum of the width of the first line segment and the width of the widened portion is greater than or equal to 1.8 micrometers.
[0011] In the display panel provided in the embodiments of the present invention, the widened portion is stacked with the first line segment in the light-emitting side direction of the display panel.
[0012] In the display panel provided in the embodiment of the present invention, the widening portion is disposed separately from the first line segment, and the widening portion is located on the side of the first line segment close to the display area.
[0013] In the display panel provided in the embodiments of the present invention, each of the protective components includes a blocking part, the blocking part is separately disposed from the fan-out wiring, the blocking part is disposed on the same layer as the inclined section, and the blocking part is located on the side of the inclined section closer to the display area.
[0014] In the display panel provided in the embodiments of the present invention, the blocking part includes a plurality of blocking line segments, and the plurality of blocking line segments are separately arranged.
[0015] In the display panel provided in the embodiments of the present invention, the width of the blocking line segment is equal to the width of the inclined segment in the extension direction perpendicular to the inclined segment.
[0016] In the display panel provided in the embodiments of the present invention, in the extending direction of the straight segment, the distance between the blocking portion and the inclined segment is smaller than the distance between two adjacent inclined segments.
[0017] This invention also provides a display terminal, including a terminal body and the aforementioned display panel, wherein the terminal body and the display panel are integrated into one unit.
[0018] Beneficial Effects: The present invention provides a display panel including a display area and a fan-out area located on one side of the display area. The fan-out area includes multiple insulated fan-out traces, each fan-out trace including a straight section and an inclined section. The inclined section is electrically connected to the end of the straight section away from the display area, and the inclined section and the straight section are set at an obtuse angle. The display panel also includes multiple protective components, each corresponding to one of the inclined sections of the fan-out traces, and each protective component is positioned close to its corresponding inclined section. The orthographic projection of each protective component onto the plane where the fan-out trace is located... The region between two adjacent straight segments has an angle greater than 0 degrees and less than 180 degrees with the straight segments. This invention protects the corners of the fan-out routing lines by setting protective components corresponding to the inclined segments in the region between two adjacent straight segments. Each protective component is set close to the corresponding inclined segment, and the angle between the orthographic projection of each protective component on the plane where the fan-out routing line is located and the straight segment is greater than 0 degrees and less than 180 degrees. This enhances the stability of the fan-out routing lines and reduces the risk of line breakage at the corners of the fan-out routing lines, thereby achieving an ultra-narrow bezel.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. In the drawings, for clarity and ease of understanding and description, the dimensions and thicknesses of the components shown are not to scale.
[0030] Please see Figure 1 This is a basic structural diagram of a fan-out trace in the prior art, specifically a structural diagram of a fan-out trace actually fabricated in the prior art. It can be understood that after compressing the border, the linewidth of the fan-out trace is correspondingly compressed. Figure 1 It is quite obvious that the trace at the corner C of the fan-out trace is significantly thinner, posing a higher risk of breakage. The embodiments of the present invention can solve the above-mentioned defects.
[0031] like Figure 2 The diagram shows a basic structural schematic of a display panel provided in an embodiment of the present invention. The display panel includes a display area A1 and a fan-out area A2 located on one side of the display area A1. The fan-out area A2 includes multiple fan-out traces 10 that are insulated from each other. Each fan-out trace 10 includes a straight section 101 and an inclined section 102. The inclined section 102 is electrically connected to the end of the straight section 101 away from the display area A1. The inclined section 102 and the straight section 101 form an obtuse angle (the angle between the inclined section 102 and the straight section 101 is obtuse). The angle c between 01 and 01 is greater than 90 degrees and less than 180 degrees. The display panel also includes multiple protective components (not shown in the figure). Each of the multiple protective components corresponds one-to-one with the inclined segments 102 of the multiple fan-out routing lines 10. Each protective component is set close to the corresponding inclined segment 102. The orthographic projection of each protective component on the plane where the fan-out routing line 10 is located is in the area between two adjacent straight segments 101, and the angle between the protective component and the straight segment 101 is greater than 0 degrees and less than 180 degrees.
[0032] It is understandable that existing technologies achieve narrow bezels by compressing the linewidth of fan-out traces, but the actual linewidth at the corners of the fan-out traces is relatively thin, making them prone to breakage. This invention addresses this by providing protective components corresponding one-to-one with inclined segments 102 in the area between two adjacent straight segments 101. Each protective component is positioned close to its corresponding inclined segment 102, and the angle between the orthographic projection of each protective component onto the plane where the fan-out trace 10 is located and the straight segment 101 is greater than 0 degrees and less than 180 degrees. This protects the corners of the fan-out trace 10, enhancing its stability while compressing the linewidth and reducing the risk of breakage at the corners, thus achieving an ultra-narrow bezel.
[0033] In one embodiment, the display panel further includes an integrated circuit chip 20 located in the fan-out area A2. The integrated circuit chip 20 is used to provide the driving electrical signals required by the display area A1. The integrated circuit chip 20 transmits the driving electrical signals to the display area A1 through the fan-out trace 10.
[0034] Next, please refer to Figure 3 ,for Figure 2 In the first enlarged view at point B, specifically, the inclined segment 102 includes a first line segment 1021 and a second line segment 1022. The first end of the first line segment 1021 is away from the straight segment 101 and away from the display area A1 (e.g., Figure 1 One end of the first line segment 1021 is electrically connected to the second line segment 1022; the first line segment 1021 is located in the region between the straight section 101 electrically connected to the first line segment 1021 and an adjacent straight section 101; wherein, each of the protective members 30 includes a widening portion 301, the first end of the widening portion 301 is electrically connected to the straight section 101, and the second end of the widening portion 301 is electrically connected to the second line segment 1022.
[0035] It should be noted that, in combination Figure 3 The two dashed lines L1 and L2 on the fan-shaped line 10 further illustrate the division of the straight segment 101, the first line segment 1021, and the second line segment 1022. The dashed line L1 marks the boundary between the straight segment 101 and the first line segment 1021, while the dashed line L2 marks the boundary between the first line segment 1021 and the second line segment 1022. In other words, the first line segment 1021 lies in the area between the straight segment 101 on dashed line L1 and the straight segment 101 on dashed line L2.
[0036] It is understood that in this embodiment, by providing a widening portion 301 between the straight section 101 and the second line segment 1022, the widening portion 301 can widen the first line segment 1021, reduce the load effect on the wiring process due to the first line segment 1021 being too thin, reduce the risk of the first line segment 1021 breaking, and achieve the purpose of protecting the fan-out wiring 10.
[0037] In one embodiment, the widening portion 301 is fitted to the first line segment 1021. It is understood that this embodiment increases the width of the first line segment 1021 by fitting the widening portion 301 to the first line segment 1021, thereby compensating for the load on the first line segment 1021 and reducing the risk of breakage in the first line segment 1021.
[0038] It should be noted that when the widening portion 301 is attached to the first line segment 1021, the material of the widening portion 301 can be a conductive material or a non-conductive but corrosion-resistant material, which can reduce the impact of the etching solution on the first line segment 1021, protect the first line segment 1021, and improve the stability of the fan-out trace 10.
[0039] In one embodiment, the widening portion 301 is disposed on the same layer as the first line segment 1021, and the widening portion 301 is located on the side of the first line segment 1021 closer to the display area A1.
[0040] It is understood that the widening portion 301 and the first line segment 1021 are set in the same layer in this embodiment and can be formed in one exposure process. The first line segment 1021 is widened and compensated by the same layer of metal without adding any other process steps. The preparation method is simple and practical.
[0041] It should be noted that, in combination Figure 3 To understand this, by placing the widening portion 301 on the side of the first line segment 1021 close to the display area A1, this embodiment can prevent the spacing between the first line segment 1021 and the second line segment 1022 of the adjacent fan-out routing line 10 from changing, thereby preventing a short circuit between the first line segment 1021 and the second line segment 1022 of the adjacent fan-out routing line 10 and improving the stability of the fan-out routing line 10.
[0042] In one embodiment, in the extension direction perpendicular to the inclined segment 102, the sum of the width of the first segment 1021 and the width of the widened portion 301 is greater than or equal to the width of the second segment 1022.
[0043] Understandably, before the widening portion 301 was provided, the width of the first line segment 1021 was smaller than the width of the second line segment 1022 in the extension direction perpendicular to the inclined segment 102, making the first line segment 1021 prone to breakage. This embodiment addresses this by providing the widening portion 301, where the sum of the width of the first line segment 1021 and the width of the widening portion 301 is greater than or equal to the width of the second line segment 1022. In other words, the widening portion 301 increases the width of the first line segment 1021, thereby reducing the risk of breakage.
[0044] In one embodiment, in the extension direction perpendicular to the inclined segment 102, the sum of the width of the first segment 1021 and the width of the widened portion 301 is greater than or equal to 1.8 micrometers.
[0045] It should be noted that, in this embodiment, the widening part 301 specifically compensates for the portion of the first line segment 1021 whose line width is less than 1.8 micrometers, and compensates the line width of the first line segment 1021 to 1.8 micrometers or more.
[0046] In one embodiment, please refer to Figure 4 ,for Figure 3 The cross-sectional view along the D-D' direction shows the film stacking structure of the display panel in the fan-out region A2. It should be noted that... Figure 4 The illustration is given with the inclined segment 102 disposed on the same layer as the first gate metal layer and the second gate metal layer, respectively. In other embodiments, the inclined segment 102 may be disposed on the same layer as only the first gate metal layer or only the second gate metal layer.
[0047] Specifically, in this embodiment, the inclined segments 102 of the multiple fan-out traces 10 alternately run on the first gate metal layer and the second gate metal layer, that is, the inclined segments 102 of two adjacent fan-out traces 10 are located on the first gate metal layer and the second gate metal layer, respectively. Among them, the first segment 1021 of the inclined segment 102 near the display area A1 is thinner than the second segment 1022, and is prone to breakage. The present invention provides a protective member 30 at the first segment 1021. The protective member 30 includes a widening portion 301, which is disposed on the same layer as the first segment 1021 to increase the width of the first segment 1021 and reduce the risk of breakage of the first segment 1021, thereby achieving the purpose of protecting the fan-out traces 10.
[0048] It should be noted that, as Figure 4As shown, when the inclined segments 102 of two adjacent fan-out traces 10 are located in the first gate metal layer and the second gate metal layer respectively, that is, when the two adjacent inclined segments 102 are arranged in different layers, the widening portion 301 can also be arranged on the side of the first line segment 1021 away from the display area A1, that is, above the adjacent inclined segment 102. In this case, a short circuit will not occur.
[0049] In this embodiment, the display panel includes a substrate layer 40, an insulating layer 50, a planarization layer 60, a first passivation layer 70, and a second passivation layer 80. A first gate metal layer is located between the substrate layer 40 and the insulating layer 50, a second gate metal layer is located between the insulating layer 50 and the planarization layer 60, the first passivation layer 70 is located on the side of the planarization layer 60 away from the insulating layer 50, and the second passivation layer 80 is located on the side of the first passivation layer 70 away from the planarization layer 60.
[0050] In one embodiment, such as Figure 5a and Figure 5b The diagram shows the relative positional relationship between the widening portion and the first line segment provided in an embodiment of the present invention. In the light-emitting direction of the display panel, the widening portion 301 and the first line segment 1021 are stacked, and both the widening portion 301 and the first line segment 1021 are disposed on the substrate layer 40. It should be noted that in this embodiment, the widening portion 301 is positioned above the first line segment 1021 (e.g., ...). Figure 5a ) or below (e.g. Figure 5b This not only widens the first line segment 1021 in the light-emitting direction of the display panel, but also does not affect the original arrangement of the fan-out routing line 10.
[0051] Next, please refer to Figure 6 This is a basic structural diagram of the fan-out routing provided in the embodiment of the present invention, specifically a structural diagram of the fan-out routing 10 actually prepared by the present invention. The present invention widens and compensates at the first line segment 1021. After compensation, the line width of the exposed routing (first line segment 1021) is equivalent to that of the dense routing area inside (second line segment 1022), thereby reducing the risk of the first line segment 1021 breaking.
[0052] Next, please refer to Figure 7 ,for Figure 2 The second enlarged view at point B, specifically, shows that the inclined segment 102 includes a first line segment 1021 and a second line segment 1022, with the first end of the first line segment 1021 being away from the straight segment 101 and away from the display area A1 (e.g., Figure 1One end of the first line segment 1021 is electrically connected to the second line segment 1022; the first line segment 1021 is located in the area between the straight segment 101 electrically connected to the first line segment 1021 and an adjacent straight segment 101; wherein, each of the protective members 30 includes a widening portion 301, the first end of the widening portion 301 is electrically connected to the straight segment 101, and the second end of the widening portion 301 is electrically connected to the second line segment 1022. In this embodiment, the widening portion 301 is separately disposed from the first line segment 1021, and the widening portion 301 is located on the side of the first line segment 1021 near the display area A1.
[0053] It is understood that in this embodiment, the first end of the widening portion 301 is electrically connected to the straight section 101, and the second end of the widening portion 301 is electrically connected to the second line segment 1022. However, the widening portion 301 is separately disposed from the first line segment 1021. That is, the driving electrical signal on the second line segment 1022 can be transmitted to the straight section 101 through the first line segment 1021, and the driving electrical signal on the second line segment 1022 can also be transmitted to the straight section 101 through the widening portion 301. This is equivalent to the widening portion 301 being connected in parallel with the first line segment 1021. If the first line segment 1021 is broken, the driving electrical signal can still be transmitted through the widening portion 301, and will not cause abnormal display of the local screen on the display panel.
[0054] It should be noted that the material of the widened portion 301 in this embodiment is a conductive material.
[0055] Next, please refer to Figure 8 ,for Figure 2 The third enlarged view at point B shows that in this embodiment, each of the protective components 30 includes a blocking part 302. The blocking part 302 is separately disposed from the fan-out routing line 10. The blocking part 302 is disposed on the same layer as the inclined section 102. The blocking part 302 is located on the side of the inclined section 102 closer to the display area A1.
[0056] It is understood that in this embodiment, by providing a blocking part 302 on the side of the inclined segment 102 near the display area A1, the blocking part 302 can block the peripheral etching solution, preventing the etching solution from excessively etching the first line segment 1021 and causing the first line segment 1021 to break. It should be noted that the material of the blocking part 302 can be a corrosion-resistant non-conductive material or a conductive material.
[0057] In one embodiment, the blocking portion 302 includes a plurality of blocking line segments 3021, which are separately disposed. It should be noted that the blocking portion 302 is composed of a plurality of blocking line segments 3021, which are arranged parallel to the inclined section 102, and the spacing between the plurality of blocking line segments 3021 is along the axis away from the display area A1 (e.g., ...). Figure 1 The spacing between multiple blocking segments 3021 gradually decreases in the direction away from the display area A1. That is, the blocking segments 3021 near the inclined segment 102 are set more densely, which can improve the blocking effect and prevent the outer etching solution from over-etching the first segment 1021 and causing the first segment 1021 to break.
[0058] It should be noted that when the material of the blocking part 302 is a non-conductive material, the blocking part 302 will not cause a short circuit between two adjacent fan-out lines 10. In this case, the distance between the blocking part 302 and the straight sections 101 on the left and right sides can be further reduced to improve the blocking effect.
[0059] In one embodiment, the width of the blocking line segment 3021 is equal to the width of the inclined segment 102 in the extending direction perpendicular to the inclined segment 102. It should be noted that the blocking line segment 3021 and the inclined segment 102 can be fabricated using the same photomask to save production costs.
[0060] In one embodiment, in the extending direction of the straight segment 101, the distance between the blocking portion 302 and the inclined segment 102 is smaller than the distance between two adjacent inclined segments 102. It is understood that this embodiment improves the blocking effect by setting the distance between the blocking portion 302 and the inclined segment 102 to be smaller than the distance between two adjacent inclined segments 102.
[0061] In one embodiment, such as Figure 9 As shown, Figure 2 The fourth enlarged view at point B shows that each of the protective components 30 includes a widening portion 301 and a blocking portion 302. The first end of the widening portion 301 is electrically connected to the straight section 101, and the second end of the widening portion 301 is electrically connected to the second line segment 1022. The blocking portion 302 is separately disposed from the fan-out routing line 10. The blocking portion 302 is disposed on the same layer as the inclined section 102, and the blocking portion 302 is located on the side of the inclined section 102 closer to the display area A1.
[0062] It is understood that in this embodiment, the protective member 30 is divided into a widening part 301 and a blocking part 302. The widening part 301 can widen the first line segment 1021 and reduce the risk of the first line segment 1021 breaking. The blocking part 302 can block the etching solution and prevent the etching solution from over-etching the first line segment 1021, which can also reduce the risk of the first line segment 1021 breaking. This embodiment can further improve the stability of the fan-out trace 10.
[0063] In this embodiment, the widening portion 301 is fitted to the first line segment 1021. It can be understood that by fitting the widening portion 301 to the first line segment 1021, this embodiment increases the width of the first line segment 1021, compensates for the load on the first line segment 1021, and also reduces the risk of the first line segment 1021 breaking.
[0064] It should be noted that when the widening portion 301 is attached to the first line segment 1021, the material of the widening portion 301 can be a conductive material or a non-conductive but corrosion-resistant material, which can reduce the impact of the etching solution on the first line segment 1021, protect the first line segment 1021, and improve the stability of the fan-out trace 10.
[0065] In one embodiment, the widening portion 301 is disposed on the same layer as the first line segment 1021, and the widening portion 301 is located on the side of the first line segment 1021 closer to the display area A1.
[0066] It is understood that the widening portion 301 and the first line segment 1021 are set in the same layer in this embodiment and can be formed in one exposure process. The first line segment 1021 is widened and compensated by the same layer of metal without adding any other process steps. The preparation method is simple and practical.
[0067] It should be noted that, by placing the widening portion 301 on the side of the first line segment 1021 close to the display area A1, this embodiment can avoid changes in the spacing between the first line segment 1021 and the second line segment 1022 of the adjacent fan-out routing line 10, thereby preventing a short circuit between the first line segment 1021 and the second line segment 1022 of the adjacent fan-out routing line 10 and improving the stability of the fan-out routing line 10.
[0068] In one embodiment, in the extension direction perpendicular to the inclined segment 102, the sum of the width of the first segment 1021 and the width of the widened portion 301 is greater than or equal to the width of the second segment 1022.
[0069] Understandably, before the widening portion 301 was provided, the width of the first line segment 1021 was smaller than the width of the second line segment 1022 in the extension direction perpendicular to the inclined segment 102, making the first line segment 1021 prone to breakage. This embodiment addresses this by providing the widening portion 301, where the sum of the width of the first line segment 1021 and the width of the widening portion 301 is greater than or equal to the width of the second line segment 1022. In other words, the widening portion 301 increases the width of the first line segment 1021, thereby reducing the risk of breakage.
[0070] In one embodiment, in the extension direction perpendicular to the inclined segment 102, the sum of the width of the first segment 1021 and the width of the widened portion 301 is greater than or equal to 1.8 micrometers.
[0071] It should be noted that, in this embodiment, the widening part 301 specifically compensates for the portion of the first line segment 1021 whose line width is less than 1.8 micrometers, and compensates the line width of the first line segment 1021 to 1.8 micrometers or more.
[0072] In one embodiment, the widening portion 301 is stacked on top of the first line segment 1021 in the light-emitting direction of the display panel. It should be noted that, by placing the widening portion 301 above or below the first line segment 1021 in this embodiment, not only can the first line segment 1021 be widened in the light-emitting direction of the display panel, but the original arrangement of the fan-out traces 10 is not affected.
[0073] In one embodiment, the widening portion 301 is separately disposed from the first line segment 1021, and the widening portion 301 is located on the side of the first line segment 1021 closer to the display area A1. It is understood that in this embodiment, the first end of the widening portion 301 is electrically connected to the straight section 101, and the second end of the widening portion 301 is electrically connected to the second line segment 1022. However, the widening portion 301 is separately disposed from the first line segment 1021. That is, the driving electrical signal on the second line segment 1022 can be transmitted to the straight section 101 through the first line segment 1021, and the driving electrical signal on the second line segment 1022 can also be transmitted to the straight section 101 through the widening portion 301. This is equivalent to the widening portion 301 being connected in parallel with the first line segment 1021. If the first line segment 1021 is broken, the driving electrical signal can still be transmitted through the widening portion 301, preventing abnormal display of parts of the display panel.
