Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display panel and display device. 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 liquid crystal displays (LCDs), AMOLED display panels are easier to make flexible, making them a key technology for wearable and foldable products. With the development of AMOLED display technology, how to reduce bezels while ensuring the reliability of the display panel is a pressing problem that screen suppliers need to solve.

[0003] Currently, to avoid reliability issues in display panels, the wire-on-array (WOA) area typically uses high-low voltage differential grouping to separate signal traces and prevent corrosion. However, due to the limited space in the WOA area caused by the compression of display panel bezels, the distance between high- and low-voltage differential groups is insufficient. This results in electrochemical corrosion of the signal traces between high and low voltage signal traces, leading to reduced display panel reliability.

[0004] Therefore, it is necessary to provide a display panel and display device to improve this deficiency. Summary of the Invention

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0046] An embodiment of this application provides a display panel, which includes a display area and a frame area disposed on one side of the display area. The display panel also includes a substrate, at least two spaced signal trace groups, and an organic insulating layer. The signal trace groups are disposed on the substrate and located in the frame area. Each signal trace group includes multiple spaced signal traces. The signal types transmitted by any two adjacent signal trace groups are different. The organic insulating layer is disposed on the signal trace groups and has a linear insulating pattern disposed on the organic insulating layer. The linear insulating pattern is disposed between adjacent signal trace groups and insulatingly separates the signal trace groups.

[0047] In the embodiments of this application, by dividing the signal traces in the bezel area into at least two spaced signal trace groups that transmit different signal types, and by setting a linear insulating pattern on the organic insulating layer between adjacent signal trace groups, the adjacent signal trace groups are insulated and separated by the linear insulating pattern to prevent electrochemical corrosion between adjacent signal trace groups that transmit different signal types. This reduces the risk of corrosion of the signal traces in the bezel area and improves the reliability of the display panel.

[0048] Please see Figure 1 and Figure 2 , Figure 1 A top view of a display panel provided for an embodiment of this application. Figure 2 for Figure 1 The enlarged schematic diagram at point a shows that the display panel 100 includes a display area AA and a border area BA disposed on one side of the display area AA.

[0049] Please see Figure 3 and Figure 4 , Figure 3 for Figure 2 An enlarged view of point b in the middle. Figure 4The cross-sectional view of the display panel provided in the embodiment of this application along the A-A' direction shows that the display panel 100 includes a substrate 1, at least two spaced signal trace groups 2, and an organic insulating layer 3. The signal trace groups 2 are disposed on the substrate 1 and located in the bezel area BA. Each signal trace group 2 includes multiple spaced signal traces 20, and the signal types transmitted by any two adjacent signal trace groups 2 are different. The organic insulating layer 3 is disposed on the signal trace groups 2, and a linear insulating pattern 30 is disposed on the organic insulating layer 3. The linear insulating pattern 30 is disposed between adjacent signal trace groups 2 and isolates adjacent signal trace groups 2. This not only avoids signal crosstalk between signal traces transmitting different signal types, but also prevents electrochemical corrosion between adjacent signal trace groups transmitting different signal types, thereby reducing the risk of corrosion of signal traces in the bezel area and improving the reliability of the display panel.

[0050] It should be noted that the signal type can include the voltage level characteristics and directional characteristics of the signal. Each signal trace group 2 is used to transmit signals with corresponding characteristics in order to achieve accurate signal classification and efficient transmission.

[0051] In some embodiments, please refer to Figure 3 and Figure 4 The signal trace group 2 includes a first sub-signal trace group 21 and a second sub-signal trace group 22. The first sub-signal trace group 21 and the second sub-signal trace group 22 are spaced apart. The first sub-signal trace group 21 transmits DC high voltage signals, and the second sub-signal trace group 22 transmits DC low voltage signals. A linear insulation pattern 30 is provided between the first sub-signal trace group 21 and the second sub-signal trace group 22.

[0052] In some embodiments, please refer to Figure 3 and Figure 4 The linear insulating pattern 30 includes a groove 31 that extends along the extension direction of the signal trace 20. The groove 31 separates the organic insulating layer 3 above the first sub-signal trace group 21 from the organic insulating layer 3 above the second sub-signal trace group 22, preventing moisture from penetrating through the organic insulating layer 3 above the first sub-signal trace group 21 to the organic insulating layer above the second sub-signal trace group 22. This cuts off the electrochemical corrosion path between the first sub-signal trace group 21 and the second sub-signal trace group 22, thereby reducing the risk of electrochemical corrosion of the first sub-signal trace group 21 and the second sub-signal trace group 22.

[0053] In some embodiments, please refer to Figure 3The first sub-signal trace group 21 includes multiple first signal traces 211 arranged side by side with intervals. The line width of at least one first signal trace 211 is smaller than that of the other first signal traces 211. By compressing the line width of some of the first signal traces 211, the distance between the first sub-signal trace group 21 and the second sub-signal trace group 22 is increased. This not only reduces the risk of crosstalk between the first sub-signal trace group 21 and the second sub-signal trace group 22, but also facilitates the addition of grooves 31 on the organic insulating layer 3 between the first sub-signal trace group 21 and the second sub-signal trace group 22. The grooves 31 are used to isolate the organic insulating layer 3 above the first sub-signal trace group 21 from the organic insulating layer 3 above the second sub-signal trace group 22, thereby reducing the risk of electrochemical corrosion between the first sub-signal trace group 21 and the second sub-signal trace group 22.

[0054] In some embodiments, please refer to Figure 3 The first sub-signal trace group 21 includes a light-emitting control signal line 2111. The line width of the light-emitting control signal line 2111 is smaller than the line width of other first signal traces 211. By compressing the line width of the light-emitting control signal line 2111, the distance between the first sub-signal trace group 21 and the second sub-signal trace group 22 is increased. This not only reduces the risk of crosstalk between the first sub-signal trace group 21 and the second sub-signal trace group 22, but also facilitates the addition of a linear insulating pattern 30 on the organic insulating layer 3 between the first sub-signal trace group 21 and the second sub-signal trace group 22. The linear insulating pattern 30 is used to isolate the organic insulating layer 3 above the first sub-signal trace group 21 from the organic insulating layer 3 above the second sub-signal trace group 22, thereby reducing the risk of electrochemical corrosion between the first sub-signal trace group 21 and the second sub-signal trace group 22.

[0055] Please see Figure 2 The line width of the light emission control signal line 2111 is greater than or equal to 15 micrometers and less than or equal to 25 micrometers, and the line width of the other first signal traces 211 is greater than or equal to 40 micrometers and less than or equal to 85 micrometers.

[0056] In some embodiments, the first signal line 211 may include, but is not limited to, a gate high voltage signal line and an analog signal line, and the light emission control signal line 2111, the gate high voltage signal line and the analog signal line all transmit DC high voltage signals.

[0057] In some embodiments, please refer to Figure 3The second sub-signal trace group 22 includes multiple second signal traces 221, which are arranged side-by-side at intervals. At least one second signal trace 221 has a line width smaller than the other second signal traces 221. By compressing the line width of some of the second signal traces 221, the distance between the first sub-signal trace group 21 and the second sub-signal trace group 22 is increased. This not only reduces the risk of crosstalk between the first sub-signal trace group 21 and the second sub-signal trace group 22, but also facilitates the addition of a linear insulating pattern 30 on the organic insulating layer 3 between the first sub-signal trace group 21 and the second sub-signal trace group 22. The linear insulating pattern 30 separates the organic insulating layer 3 above the first sub-signal trace group 21 from the organic insulating layer 3 above the second sub-signal trace group 22, thereby reducing the risk of electrochemical corrosion between the first sub-signal trace group 21 and the second sub-signal trace group 22.

[0058] In some embodiments, the second sub-signal trace group 22 includes an initial light emission signal line 2211 and an output light emission signal line 2212, wherein the line width of at least one of the initial light emission signal line 2211 and the output light emission signal line 2212 is smaller than the line width of the other second signal traces 221.

[0059] Please see Figure 3 The linewidths of the initial light emission signal line 2211 and the light emission output signal line 2212 are greater than or equal to 15 micrometers and less than or equal to 25 micrometers, and the linewidths of other second signal lines 221 are greater than or equal to 40 micrometers and less than or equal to 85 micrometers.

[0060] In some embodiments, the second signal line 221 may include, but is not limited to, the gate low voltage signal line, and the light emission initial signal line 2211, the light emission output signal line 2212 and the gate low voltage signal line may all transmit a DC low voltage signal.

[0061] In some embodiments, please refer to Figure 3 The signal trace group 2 also includes a third sub-signal trace group 23, which transmits AC signals. The third sub-signal trace group 23 is located on the side of the first sub-signal trace group 21 away from the second sub-signal trace group 22. A linear insulation pattern 30 is provided between the first sub-signal trace group 21 and the third sub-signal trace group 23.

[0062] Please see Figure 2 and Figure 3The groove 31 separates the organic insulating layer 3 above the first sub-signal trace group 21 from the organic insulating layer 3 above the third sub-signal trace group 23, preventing moisture from penetrating through the organic insulating layer 3 above the first sub-signal trace group 21 to the organic insulating layer above the third sub-signal trace group 23. This cuts off the electrochemical corrosion path between the first sub-signal trace group 21 and the third sub-signal trace group 23, thereby reducing the risk of electrochemical corrosion between the first sub-signal trace group 21 and the third sub-signal trace group 23.

[0063] In some embodiments, please refer to Figure 3 The third sub-signal routing group 23 includes multiple third signal traces 231, and the line width of the third signal traces 231 is greater than or equal to the line width of the signal traces in the first sub-signal routing group 21 and the second sub-signal routing group 22.

The first routing area WOA1 is located between the display area AA and the bending area BA1, and the second routing area WOA2 is located between the bending area BA1 and the terminal area BA2. The first routing area WOA1 has at least two signal routing groups 2 and a linear insulation pattern 30 located between adjacent signal routing groups 2; and / or, the second routing area WOA2 has at least two signal routing groups 2 and a linear insulation pattern 30 located between adjacent signal routing groups 2.

[0065] In some embodiments, please refer to Figures 1 to 4 The second routing area WOA2 is provided with a first sub-signal routing group 21, a second sub-signal routing group 22 and a third sub-signal routing group 23. A linear insulation pattern 30 is provided between two adjacent signal routing groups 2, which can reduce the risk of electrochemical corrosion of the signal routing in the second routing area WOA2.

[0066] In other embodiments, the first routing area WOA1 may also be provided with at least two signal routing groups 2 and a linear insulation pattern 30 located between adjacent signal routing groups 2. The arrangement of the signal routing groups 2 and the linear insulation pattern 30 can be referred to Figure 3 The settings for the second routing area WOA2 shown are not described in detail here.

[0067] In some embodiments, please refer to Figure 3The display panel 100 also includes at least two connection line groups 4 corresponding one-to-one with the signal trace group 2. The connection line groups 4 are located between the bending area BA1 and the terminal area BA2. Each connection line group 4 includes multiple spaced connection lines 40. The connection line groups 4 and the signal trace group 2 are arranged on different layers. One end of the connection line 40 is used to connect to the integrated circuit chip 6, and the other end of the connection line 40 is connected to the corresponding signal trace 20. The other end of the signal trace 20 is connected to the terminal of the terminal area BA2, and the terminal of the terminal area BA2 is used for bonding to the flexible circuit board. In the second trace area WOA2, the signal trace 20 is connected to the connection line 40 through vias, thereby enabling trace switching in the second trace area WOA2.
