Description

Technical Field

[0001] The present disclosure relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] Oxide thin-film transistor technology has excellent performance with lower leakage current and higher device switching ratio. When applied to liquid crystal display products that use low-frequency liquid crystal materials, it can maintain pixel voltage for an extremely long time and suppress the gate effect of the device. It not only ensures high-definition display and high refresh rate, but also can achieve ultra-long battery life through dynamic frequency modulation, meeting users' demand for high-end notebooks.

[0003] While achieving ultra-low frequency refresh, it is also necessary to control the flicker (JEITA method flicker) within -55dB.

[0057] In the following, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present disclosure, and different embodiments may be combined in any manner without conflict. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0058] Figure 1 FIG. 1 is a partial plan view of a display panel in a related art. Figure 1 As shown, the display panel includes a display area AA, a fan-shaped routing area FA and an intermediate routing area MA. The fan-shaped routing area FA is located on the lower side of the display area AA, and the intermediate routing area MA is located between the display area AA and the fan-shaped routing area FA. In the related art, the display area AA is not only provided with multiple data lines D, but also with multiple touch signal lines TX. The display panel also includes a binding area (not shown in the figure) located on the lower side of the fan-shaped routing area FA, and the binding area is provided with a control module. The data line D is connected to the control module through a data adapter line, and the touch signal line TX is connected to the control module through a touch adapter line. Therefore, both the data adapter line and the touch adapter line pass through the fan-shaped routing area FA, that is, at least part of the data adapter line is located in the fan-shaped routing area FA, and at least part of the touch adapter line is located in the fan-shaped routing area FA. This results in a relatively large number of signal lines in the fan-shaped routing area FA.

[0059] In related art, the fan-shaped routing area FA uses a double-layer wiring configuration, with a first metal layer M1 and a second metal layer M2, with a first insulating layer 21 disposed between the two metal layers. The touch interface cables are all disposed on the second metal layer M2, while some data interface cables are disposed on the first metal layer M1 and some on the second metal layer M2.

[0060] For example, in Figure 1In the example, four columns of data lines D form a connection cycle. The data transfer line corresponding to the first column of data lines D1 is located in the first metal layer M1, the data transfer line corresponding to the second column of data lines D2 is located in the second metal layer M2, the data transfer line corresponding to the third column of data lines D3 is located in the first metal layer M1, and the data transfer line corresponding to the fourth column of data lines D4 is located in the first metal layer M1. Therefore, the film layer positions of the data transfer lines corresponding to these four columns of data lines are M1 / M2 / M1 / M1, respectively. In other words, for every four columns of data lines D, the data transfer line corresponding to one even-numbered data line D is located in the second metal layer M2. In other words, for every four columns of data lines D, one even-numbered data line D is driven by the second metal layer M2.

[0061] Assuming that the data lines D are all located in the second metal layer M2, the data transfer lines located in the first metal layer M1 are connected to the corresponding data lines D through vias in the middle routing area MA. Figure 1 In the example, the first column of data lines D1, the third column of data lines D3, and the fourth column of data lines D4 are connected to corresponding data patch cables through vias. The second column of data lines D2 and the corresponding data patch cables are located on the same metal layer, so the second column of data lines D2 and the corresponding data patch cables are directly connected on the second metal layer M2. Every four columns of data lines D are connected to the corresponding data patch cables using the same connection cycle.

[0062] Figure 1 In FIG, the film layer positions of the data transfer wires corresponding to the eight adjacent columns of data lines D are M1 / M2 / M1 / M1|M1 / M2 / M1 / M1.

[0063] The display panel can be driven by half-frequency. In one frame, a positive voltage + is provided to the odd-numbered data lines DO and a negative voltage is provided to the even-numbered data lines DE; alternatively, a positive voltage + is provided to the even-numbered data lines DE and a negative voltage is provided to the odd-numbered data lines DO. The positive and negative voltages herein are both relative to the common electrode voltage. A positive voltage is greater than the common electrode voltage, and a negative voltage is less than the common electrode voltage. The absolute value of the difference between the positive voltage and the common electrode voltage is a first absolute value, and the absolute value of the difference between the negative voltage and the common electrode voltage is a second absolute value. The first absolute value and the second absolute value are equal.

[0064] Figure 1 When the data lines D in the middle 8 columns are driven at half frequency, the voltage signals corresponding to the data lines D are shown in Table 1.

[0065] Table 1

[0066] Number of columns D1 D2 D3 D4 D5 D6 D7 D8 Voltage + - + - + - + -

[0067] As can be seen in Table 1, the odd-numbered data lines DO are supplied with a positive voltage (+), while the even-numbered data lines DE are supplied with a negative voltage (-). Among the even-numbered data lines DE, the data adapter lines corresponding to the second and sixth data lines D2 and D6 are located in the second metal layer M2, while the data adapter lines corresponding to the remaining data lines D are located in the first metal layer M1. Among the odd-numbered data lines DO, the data adapter lines corresponding to all data lines D are located in the first metal layer M1. In other words, among the even-numbered data lines DE, the second and sixth data lines D2 and D6 are driven by the data adapter lines in the second metal layer M2, while the remaining data lines D are driven by the data adapter lines in the first metal layer M1. All the odd-numbered data lines DO are driven by the data adapter lines in the first metal layer M1.

[0068] Differences in film layer processing in the display panel result in different resistances of the data adapter lines in different metal layers, and different connection resistances between different data adapter lines and data lines D. Therefore, when the second column data line D2 and the sixth column data line D6 are driven by the data adapter lines of the second metal layer M2, and the other data lines D are driven by the data adapter lines of the first metal layer M1, the data adapter lines of the second metal layer M2 have an uneven effect on the even column data lines DE and the odd column data lines DO, which results in uneven driving of the odd column data lines DO and the even column data lines DE, or in other words, uneven pulling of the odd and even columns. In addition, the line width of the data adapter lines of the second metal layer M2 and the line width of the data adapter lines of the first metal layer M1 cannot meet the design requirements in terms of process control, further resulting in uneven pulling of the odd and even columns, resulting in poor half-frequency flicker results and failure to meet the half-frequency flicker requirements.

[0069] In order to solve some problems in the prior art, an embodiment of the present disclosure provides a display panel.

[0070] It should be noted that in this document, different data lines in the same figure are distinguished by Arabic numerals, for example, D1, D2, D3, .... Odd Arabic numerals indicate that the data line is an odd-numbered data line, and even Arabic numerals indicate that the data line is an even-numbered data line. Different touch signal lines in the same figure are distinguished by Arabic numerals, for example, TX1, TX2, .... Different first adapter cables in the same figure are distinguished by lowercase English letters, for example, 11a, 11b, 11c, ...; different second adapter cables in the same figure are distinguished by lowercase English letters, for example, 12a, 12b, 12c, ....

[0071] Figure 2-Figure 10 They are partial plan views of display panels in different embodiments of the present disclosure, Figure 2-Figure 10 The data lines D and the corresponding data transfer lines in a part of the display panel are shown. Figure 2-Figure 10As shown, the display panel includes a display area AA and a fan-shaped routing area FA located on one side of the display area AA along a first direction. The display panel includes multiple data lines D and multiple data transfer lines. The data lines D extend along the first direction in the display area AA, and the multiple data lines D are arranged in sequence along the second direction in the display area AA. The second direction intersects the first direction, for example, the second direction can be perpendicular to the first direction. Figure 2-Figure 10 In the embodiment, the first direction is the vertical direction, and the second direction is the horizontal direction. Multiple data transfer lines are connected to multiple data lines D in a one-to-one correspondence, and at least a portion of the data transfer lines is located in the fan-shaped routing area FA. In the fan-shaped routing area FA, the multiple data transfer lines can be routed in a fan-shaped shape.

[0072] The multiple data transfer lines may include multiple first transfer lines 11 and multiple second transfer lines 12. The display panel includes a first metal layer M1 and a second metal layer M2, with a first insulating layer 21 disposed between the first metal layer M1 and the second metal layer M2. The first transfer lines 11 are data transfer lines located in the second metal layer M2, and the second transfer lines 12 are data transfer lines located in the first metal layer M1. The number of first transfer lines 11 is less than or equal to half the number of data transfer lines.

[0073] At least one of the plurality of first adapter lines 11 is connected to the even-numbered data lines DE, and at least one is connected to the odd-numbered data lines DO. The plurality of first adapter lines 11 are connected to the corresponding plurality of data lines D in a one-to-one correspondence, and the remaining data lines D are all connected to the corresponding second adapter lines 12.

[0074] Exemplarily, the first adapter line 11 and the data line D may be provided at the same layer, or the second adapter line 12 and the data line D may be provided at the same layer.

[0075] The display panel may further include an intermediate routing area MA located between the display area AA and the fan-shaped routing area FA. Data transfer lines on the same layer as the data lines D may be connected to the data lines D in the intermediate routing area MA through metal on the same layer. Data transfer lines on different layers from the data lines D may be connected to the data lines D in the intermediate routing area MA through vias.

[0076] In related technologies, such as Figure 1 As shown, part of the even-numbered data lines DE are connected to the data transfer lines located on the second metal layer M2, and the other part is connected to the data transfer lines located on the first metal layer M1; while the odd-numbered data lines DO are all connected to the data transfer lines located on the first metal layer M1, resulting in poor half-frequency flicker results.

[0077] The technical solution of the disclosed embodiment, by providing at least one first adapter line 11 connected to the even-numbered data lines DE and at least one first adapter line 11 connected to the odd-numbered data lines DO, allows at least one of the odd-numbered data lines DO to be connected to the first adapter line 11 located in the second metal layer M2, and at least one of the even-numbered data lines DE to be connected to the first adapter line 11 located in the second metal layer M2. This avoids the situation where only the even-numbered data lines DE are connected to the first adapter line 11 located in the second metal layer M2, or only the odd-numbered data lines DO are connected to the first adapter line 11 located in the second metal layer M2. Compared to the related art, the technical solution of the disclosed embodiment improves the uneven influence of the first adapter line 11 on the odd-numbered data lines DO and the even-numbered data lines DE. Thus, when half-frequency driving is adopted, the uneven driving of the odd-numbered data lines DO and the even-numbered data lines DE can be improved, the uneven pulling of the odd and even columns can be improved, the problem of poor half-frequency flicker results can be improved, the half-frequency flicker effect can be improved, and the display quality of the display panel at low frequencies can be enhanced.

[0078] It should be noted that in the present disclosure Figure 2-Figure 10 In order to clearly show the film layer position relationship of each routing line in the drawings, each drawing provides one or two cross-sectional views in the plan view, and also uses a table to show the corresponding relationship between the data line and the data adapter line, and the table also shows the film layer where the adapter line is located. For example, Figure 2 Not only is a planar schematic diagram of the connection relationship between the data line and the data adapter line in the display panel provided, but also a corresponding BB cross-sectional diagram is provided, and a table is also provided. It can be seen from the table that the data adapter line corresponding to the data line D1 is the second adapter line 12a, and the second adapter line 12a is located in the first metal layer M1. The data adapter line corresponding to the data line D2 is the first adapter line 11a, and the first adapter line 11a is located in the second metal layer M2.

[0079] In one embodiment, the number of first adapter lines 11 can be an even number, with half of the multiple first adapter lines 11 connected to the even-numbered column data lines DE, and the other half connected to the odd-numbered column data lines DO. With this arrangement, the number of even-numbered column data lines DE and odd-numbered column data lines DO connected to the first adapter lines 11 is the same, further alleviating the uneven impact of the first adapter lines 11 on the odd-numbered column data lines DO and the even-numbered column data lines DE. When half-frequency driving is employed, this can further alleviate the uneven driving of the odd-numbered column data lines DO and the even-numbered column data lines DE, improve the uneven pulling of the odd and even columns, and improve the problem of poor half-frequency flicker results.

[0080] In order to facilitate the connection design between the data line D and the data adapter line, in one embodiment, the display panel is provided with at least one connection period along the second direction. For example, the display panel is provided with multiple connection periods along the second direction. Figure 2FIG. 1 shows a connection cycle in one embodiment, Figure 3 FIG. 1 shows a connection cycle in another embodiment, Figure 4-Figure 7 A connection cycle in different embodiments is shown respectively. Figures 8-10 It is understood that the display panel can be provided with a connection period along the second direction, for example, all data lines D and all data transfer lines in the display panel belong to the same connection period.

[0081] like Figure 2-Figure 10 As shown, the connection period includes M data lines D and M data transfer lines arranged in sequence along the second direction, and the M data transfer lines are connected to the M data lines D in a one-to-one correspondence. The M data transfer lines include N first transfer lines 11, at least one of the N first transfer lines 11 is connected to the even-numbered data lines DE among the M data lines D, and at least one is connected to the odd-numbered data lines DO among the M data lines D. M can be an even number greater than or equal to 4. For example, M can be a multiple of 4. N is a positive integer greater than or equal to 2, and N is less than or equal to half of M. The data transfer lines other than the N first transfer lines 11 among the M data transfer lines are second transfer lines 12, and the second transfer lines 12 are connected to the corresponding data lines D.

[0082] The display panel is set to at least one connection cycle along the second direction. When there are multiple connection cycles, the connection relationship between the data transfer lines and the corresponding data lines in different connection cycles is the same, the film layer where the corresponding data transfer lines are located in different connection cycles is the same, and the wiring method of the middle routing area MA is the same. Therefore, when setting up connection wiring for a large number of data lines D and data transfer lines, it is only necessary to repeat the connection cycle, and there is no need to separately set the wiring of each data line D and the data transfer line in the middle routing area MA, which facilitates the connection wiring of a large number of data lines D and data transfer lines and improves the efficiency of wiring design.

[0083] It should be noted that the connection cycle in this article mainly refers to the wiring method of the middle wiring area MA, specifically including the film layer position of the data transfer line in the middle wiring area MA and the connection relationship between the data line D and the data transfer line. In the two connection cycles, the film layer position of the corresponding data transfer line is the same, and the connection method between the corresponding data line D and the data transfer line is the same. For example, Figure 2 In the embodiment, the middle routing area MA of different connection periods can all adopt Figure 2The wiring method of the middle routing area in the . For example, in the first connection cycle, the data transfer line corresponding to the second column of data line D is located on the second metal layer M2, and in the second connection cycle, the data transfer line corresponding to the second column of data line D is also located on the second metal layer M2; in the first connection cycle, the third column of data line D is connected to the data transfer line through a via, and in the second connection cycle, the third column of data line D is also connected to the data transfer line through a via.

[0084] By providing N first adapter lines 11, and at least one of the N first adapter lines 11 is connected to the even-numbered data lines DE among the M data lines D, and at least one is connected to the odd-numbered data lines DO among the M data lines D, it is possible to achieve that in each connection cycle, at least one even-numbered data line DE is connected to the first adapter line 11, and at least one odd-numbered data line DO is coupled to the first adapter line 11. This can improve the uneven impact of the first adapter line 11 on the odd-numbered data lines DO and the even-numbered data lines DE in the corresponding area of ​​each connection cycle, improve the uneven driving of the odd-numbered data lines DO and the even-numbered data lines DE, and improve the problem of poor half-frequency flicker results in the corresponding area of ​​each connection cycle. When multiple connection cycles are repeated, the problem of poor half-frequency flicker results in the full-screen area can be further improved.

[0085] In one embodiment, N is an even number, half of the N first switching lines 11 are connected to the even-numbered data lines DE among the M data lines D, and the other half are connected to the odd-numbered data lines DO among the M data lines D.

[0086] For example, Figure 2 In one connection cycle, M=8, N=2, and the eight data transfer lines include two first transfer lines 11. Of the two first transfer lines 11, first transfer line 11a is connected to data line D2 in the second column, which is an even-numbered column data line DE. Another first transfer line 11b is connected to data line D7 in the seventh column, which is an odd-numbered column data line DO. The data transfer lines other than first transfer lines 11 are second transfer lines 12. For example, second transfer lines 12 include second transfer lines 12a, 12b, 12c, 12d, 12e, and 12f. These second transfer lines 12 are connected to data lines D1, D3, D4, D5, D6, and D8, respectively.

[0087] For example, Figure 3In the example, M=16, N=4. Two first adapter lines 11a and 11c are connected to the first and eleventh data lines D11, respectively. These lines are odd-numbered data lines DO. The other two first adapter lines 11b and 11c are coupled to the sixth and sixteenth data lines D6, respectively. These lines are even-numbered data lines DE. The data adapter lines other than the first adapter lines 11 are second adapter lines 12, which are connected one-to-one with corresponding data lines D.

[0088] Figure 4-10 The corresponding embodiments are also the same and will not be listed here one by one.

[0089] In this way, in each connection cycle, the number of odd-numbered data lines DO connected to the first adapter line 11 and the number of even-numbered data lines DE connected to the first adapter line 11 are the same, which further improves the uneven influence of the first adapter line 11 on the odd-numbered data lines DO and the even-numbered data lines DE in the corresponding area of ​​one connection cycle, improves the uneven driving of the odd-numbered data lines DO and the even-numbered data lines DE, and improves the problem of poor half-frequency Flicker results in the corresponding area of ​​each connection cycle.

[0090] In one embodiment, the data lines D corresponding to the first adapter lines 11 are arranged symmetrically among the M data lines D. For example, Figure 2 In the figure, a connection cycle includes two first adapter lines 11. The first adapter line 11a corresponds to the data line D2, and the first adapter line 11b corresponds to the data line D7. The data line D2 and the data line D7 are arranged symmetrically among the eight data lines. The data adapter lines corresponding to the data line D2 and the data line D7 are both first adapter lines 11, and the other data adapter lines are second adapter lines 12. The first adapter line 11 is located in the second metal layer M2, and the second adapter line 12 is located in the first metal layer M1. Therefore, the film layer arrangement position of the eight data adapter lines is M1 / M2 / M1 / M1|M1 / M1 / M2 / M1. From this arrangement position, it can also be seen that the data lines D corresponding to the two first adapter lines 11 are arranged in the 2nd and 7th columns among the M data lines D, respectively, and the two arrangement positions are symmetrical.

[0091] In the embodiment of the present disclosure, the arrangement positions of the first adapter lines 11 in the M data lines D are set to be symmetrical, so that within the corresponding area of ​​the connection period, the influence of the first adapter lines 11 on the odd-column data lines DO and the even-column data lines DE is also symmetrical. Therefore, the influence of the first adapter lines 11 on the odd-column data lines DO and the even-column data lines DE is balanced, which can greatly improve the problem of poor half-frequency Flicker results in the corresponding area of ​​each connection period.

[0092] It should be noted that, in this article, the arrangement positions are symmetrical, which can be understood as, for M=8, the 1st and 8th positions are symmetrical, the 2nd and 7th positions are symmetrical, the 3rd and 6th positions are symmetrical, and the 4th and 5th positions are symmetrical.

[0093] Figure 3 In the embodiment, the arrangement positions of the 16 data adapter lines in the 16 data lines D are M2 / M1 / M1 / M1|M1 / M2 / M1 / M1|M1 / M1 / M2 / M1|M1 / M1 / M1 / M2. From the arrangement positions, it can be seen that the four first adapter lines 11 are located at the 1st position, the 6th position, the 11th position and the 16th position, respectively, wherein the arrangement positions of the 1st position and the 16th position are symmetrical, and the arrangement positions of the 6th position and the 11th position are symmetrical.

[0094] Figure 7 In this embodiment, a connection cycle includes four data lines D and four data adapter lines. The four data adapter lines are arranged in the order M2 / M1 / M1 / M2 within the four data lines D. As can be seen from this arrangement, the two first adapter lines 11 are located at the first and fourth positions, respectively, and the two positions are symmetrically arranged.

[0095] Figure 4 and Figure 9 In the corresponding embodiment, in one connection cycle, the arrangement positions of the first adapter wires 11 among the M data lines D are also symmetrical, which will not be listed one by one for explanation.

[0096] In one embodiment, in order to facilitate the setting of at least one first transfer line 11 connected to the odd-numbered data line DO, at least one first transfer line 11 connected to the even-numbered data line DE, and at least two first transfer lines 11 among the N first transfer lines 11 are correspondingly connected to at least two adjacent data lines D among the M data lines D.

[0097] In the second direction, multiple data lines D are arranged in sequence, and one of the two adjacent data lines D must be an even-numbered column data line DE and the other is an odd-numbered column data line DO. At least two first adapter lines 11 are set to be connected to the corresponding at least two adjacent data lines D, so that at least one first adapter line 11 can be connected to the odd-numbered column data line DO, and at least one first adapter line 11 can be connected to the even-numbered column data line DE, which facilitates wiring design.

[0098] For example, Figure 4 In the embodiment, the data transfer lines corresponding to the data lines D2 and D3 are both first transfer lines 11, and the two first transfer lines 11 are connected to the adjacent second column data lines D and third column data lines D in a one-to-one correspondence. Figure 5In the embodiment, the data adapter lines corresponding to the data lines D1 and D2 are two first adapter lines 11 , and the two first adapter lines 11 are connected to the adjacent first column data lines D1 and second column data lines D2 in a one-to-one correspondence. Figure 6 In the embodiment, the data adapter wires corresponding to the data lines D3 and D4 are two first adapter wires 11 , and the two first adapter wires 11 are connected to the adjacent third column data lines D3 and fourth column data lines D4 in a one-to-one correspondence.

[0099] Figure 8 In the embodiment, the data adapter wires corresponding to the data lines D2 and D3 are both first adapter wires 11 , and the two first adapter wires are connected to the adjacent second column data lines D2 and third column data lines D3 in a one-to-one correspondence.

[0100] In one embodiment, the connection period may include at least two connection units arranged along the second direction, wherein the connection unit includes P data lines D arranged sequentially along the second direction and P data patch lines corresponding to the P data lines D. The P data patch lines include W first patch lines 11. The data line D corresponding to at least one first patch line 11 in each connection unit has a different arrangement position among the P data lines D, where W is a positive integer greater than or equal to 1 and less than or equal to half of P.

[0101] For example, Figure 2 In this embodiment, the connection cycle includes two connection units, with P = 4 and W = 1. In the first connection unit, the second column of data line D2 is connected to the first patch line 11a; in the second connection unit, the third column of data line D3 is connected to the first patch line 11b. The data lines D corresponding to the first patch line 11 in the two connection units are in the second and third columns, respectively, and are arranged in different positions.

[0102] It should be noted that when the connection cycle includes two or more connection units, in each connection unit, the data lines are arranged in sequence. For example, Figure 2 In the embodiment, the data lines D5, D6, D7 and D8 are located in the second connection unit. In the connection unit, the data lines D5, D6, D7 and D8 are arranged in the first column, the second column, the third column and the fourth column, respectively.

[0103] Figure 3In this embodiment, the connection cycle includes four connection units, with P=4 and W=1. In the first connection unit, the first column of data line D1 is connected to the first adapter line 11a; in the second connection unit, the second column of data line D6 is connected to the first adapter line 11b; in the third connection unit, the third column of data line D11 is connected to the first adapter line 11c; and in the fourth connection unit, the fourth column of data line D16 is connected to the first adapter line 11d. Data line D1 is arranged in the first column in the corresponding connection unit, data line D6 is arranged in the second column in the corresponding connection unit, data line D11 is arranged in the third column in the corresponding connection unit, and data line D16 is arranged in the fourth column in the corresponding connection unit. The data lines D corresponding to the first adapter line 11 in the four connection units are arranged in the first, second, third, and fourth columns, respectively, and their arrangement positions are different.

[0104] Figure 8 In this embodiment, the connection cycle includes two connection units, with P = 4 and W = 2. In the first connection unit, the data lines D in the second and third columns are both connected to the first patch line 11; in the second connection unit, the data lines D in the first and fourth columns are both connected to the first patch line 11. The data lines D corresponding to the first patch line 11 in the two connection units are arranged in different positions: the first and third columns, and the first and fourth columns, respectively.

[0105] Figure 9 In this embodiment, the connection cycle includes two connection units, with P = 4 and W = 2. In the first connection unit, the data lines D in the third and fourth columns are both connected to the first patch line 11; in the second connection unit, the data lines D in the first and second columns are both connected to the first patch line 11. The data lines D corresponding to the first patch line 11 in the two connection units are arranged in different positions: the third and fourth columns, and the second and third columns, respectively.

[0106] Figure 10 In this embodiment, the connection cycle includes four connection units, with P=4 and W=2. In the first connection unit, the data lines D in the second and third columns are both connected to the first adapter line 11; in the second connection unit, the data lines D in the first and fourth columns are both connected to the first adapter line 11; in the third connection unit, the data lines D in the third and fourth columns are both connected to the first adapter line 11; and in the fourth connection unit, the data lines D in the first and second columns are both connected to the first adapter line 11. The data lines D corresponding to the first adapter line 11 in the four connection units are, respectively, the second and third columns, the first and fourth columns, the third and fourth columns, and the first and second columns. The arrangement positions of the data lines D corresponding to at least one first adapter line 11 in each of the four connection units are different.

[0107] It should be noted that Figure 8 、 Figure 9 、 Figure 10 The arrangement positions of the multiple connection units can be set as needed and are not limited to the arrangement shown in the figure. Figure 8 The positions of the two connection units can be swapped. Figure 10 The arrangement positions of the four connection units can be set as needed.

[0108] This setting method divides the connection period into at least two connection units. By setting the data line D corresponding to at least one first adapter line 11 in each connection unit to have different arrangement positions among the P data lines D, the influence of the first adapter line 11 on the corresponding areas of different connection units can be improved, thereby further improving the uneven influence of the first adapter line 11 on the odd-column data lines DO and the even-column data lines DE, improving the problem of poor half-frequency flicker results, and reducing the flicker difference between odd and even columns.

[0109] For example, for the connection unit, W can be an even number, half of the W first transfer lines 11 are connected to the even-numbered data lines DE among the P data lines D, and the other half are connected to the odd-numbered data lines DO among the P data lines D. Figure 8 、 Figure 9 and Figure 10 In the embodiment, each connection unit has two first transfer lines 11 , wherein one first transfer line 11 is connected to the even-numbered data lines DE, and the other first transfer line 11 is connected to the odd-numbered data lines DO.

[0110] In one embodiment, the connection period includes a first portion and a second portion along the second direction, wherein the number of connection units in the first portion and the second portion is the same. The data lines D corresponding to the first patch lines 11 in each connection unit in the first portion are arranged in different positions within the connection unit. The data lines D corresponding to the first patch lines 11 in each connection unit in the second portion are arranged in different positions within the connection unit.

[0111] When the number of the connection units in the first part and the second part is 1, the arrangement position of the data line D corresponding to the first patch line 11 in the connection unit in the first part is different from the arrangement position of the data line D corresponding to the first patch line 11 in the connection unit in the second part. Figure 8 and Figure 9 shown.

[0112] For example, Figure 8In the embodiment, the first part includes one connection unit, and the second part includes one connection unit. In the connection unit of the first part, the data lines D corresponding to the first adapter lines 11a and 11b are arranged in the second and third columns, respectively. In the connection unit of the second part, the data lines D corresponding to the first adapter lines 11c and 11d are arranged in the first and fourth columns, respectively.

[0113] Figure 9 In the first part of the connection unit, the data lines D corresponding to the first adapter lines 11a and 11b are arranged in the third and fourth columns respectively. In the second part of the connection unit, the data lines D corresponding to the first adapter lines 11c and 11d are arranged in the first and second columns respectively.

[0114] When the number of connection units in the first part and the second part is greater than or equal to 2, the arrangement position of the data line D corresponding to the first patch line 11 in each connection unit of the first part is the same as the arrangement position of the data line D corresponding to the first patch line 11 in each connection unit of the second part. Figure 10 shown.

[0115] exist Figure 10 In the embodiment, the first part includes two connection units CU1 and CU2, and the second part includes two connection units CU3 and CU4. The data lines D corresponding to the first adapter lines 11 in the two connection units in the first part are arranged in the second and third columns, and the first and fourth columns, respectively. The data lines D corresponding to the first adapter lines 11 in the two connection units are arranged in different positions in the connection units.

[0116] In the second part, the data lines D corresponding to the first adapter lines 11 in the two connection units are arranged in the 3rd and 4th columns, and the 1st and 2nd columns respectively. The arrangement positions of the data lines D corresponding to the first adapter lines 11 in the two connection units are different.

[0117] Thus, it can be seen that the data lines D corresponding to the first patch cable 11 in the first section are arranged in the second and third columns, and the first and fourth columns in the connection unit; and the data lines D corresponding to the first patch cable 11 in the second section are arranged in the third and fourth columns, and the first and second columns in the connection unit. The arrangement positions of the data lines D corresponding to the first patch cable 11 in the first section and the data lines D corresponding to the first patch cable 11 in the second section are the same, namely, the first, second, third, and fourth columns.

[0118] It should be noted that, in the first part, the connection units CU1 and CU2 can be interchanged, and in the second part, the connection units CU3 and CU4 can be interchanged; the first part and the second part can be interchanged, and both can achieve the same effect.

[0119] In one embodiment, reference Figure 2 When the data lines D corresponding to the first adapter lines 11 are arranged symmetrically among the M data lines D, for the case of M=8 and N=2, among the 8 data lines D, the first column data line D1 and the eighth column data line D8 can both be connected to the first adapter line 11; or, the second column data line D2 and the seventh column data line D7 can both be connected to the first adapter line 11, as shown in FIG. Figure 2 As shown; or, the 3rd column data line D3 and the 6th column data line D6 are both connected to the first adapter line 11; or, the 4th column data line D4 and the 5th column data line D5 are both connected to the first adapter line 11.

[0120] In one embodiment, for M=4, N=2, among the four data lines D, the first column data line D1 and the second column data line D2 are both connected to the first adapter line 11, and the third column and the fourth column data line D are both connected to the second adapter line 12. Figure 5 Alternatively, the 2nd column data line D2 and the 3rd column data line D3 are connected to the first adapter line 11, and the 1st column and the 4th column data line D are connected to the second adapter line 12, as shown Figure 4 Alternatively, the 3rd column data line D and the 4th column data line D are connected to the first adapter line 11, and the 1st column and the 2nd column data line D are connected to the second adapter line 12, as shown Figure 6 or, the 4th column data line D4 and the 1st column data line D1 are connected to the first adapter line 11, and the 2nd and 3rd column data lines D are connected to the second adapter line 12, as shown. Figure 7 shown.

[0121] In one embodiment, reference Figure 8 The connection cycle includes two connection units. The connection unit includes P data lines D arranged in sequence along the second direction and P data transfer lines corresponding to the P data lines D. The P data transfer lines include W first transfer lines 11, where P=4 and W=2. In one connection unit, the second column data line D2 and the third column data line D3 are both connected to the first transfer line 11; in the other connection unit, the first column data line D5 and the fourth column data line D8 are both connected to the first transfer line 11. The other data lines D are all connected to the second transfer line 12. The arrangement order of the two connection units in the second direction can be set as needed, for example, Figure 8 The two connection units in the figure can be interchanged to achieve the same effect.

[0122] In another embodiment, reference Figure 9 The connection cycle includes two connection units, each of which includes P data lines D arranged in sequence along the second direction and P data transfer lines corresponding to the P data lines D. The P data transfer lines include W first transfer lines 11, where P=4 and W=2. In one connection unit, the third column data line D3 and the fourth column data line D4 are both connected to the first transfer line 11; in the other connection unit, the first column data line D5 and the second column data line D6 are both connected to the first transfer line 11, and the other data lines D are all connected to the second transfer line 12. The arrangement order of the two connection units in the second direction can be set as needed, for example, Figure 9 The two connection units in the figure can be interchanged to achieve the same effect.

[0123] In another embodiment, reference Figure 3 The connection cycle includes four connection units, P = 4, W = 1. The first column data line D1 in the first connection unit CU1 is connected to the first patch line 11a; the second column data line D6 in the second connection unit CU2 is connected to the first patch line 11b; the third column data line D11 in the third connection unit CU3 is connected to the first patch line 11c; and the fourth column data line D16 in the fourth connection unit CU4 is connected to the first patch line 11d. The arrangement of the four connection units in the second direction can be set as needed.

[0124] For example, refer to Figure 3 , the first connection unit CU1, the second connection unit CU2, the third connection unit CU3 and the fourth connection unit CU4 may be arranged in sequence along the second direction.

[0125] In one embodiment, reference Figure 10 , the connection period includes a first part and a second part along the first direction, and the number of connection units in the first part and the second part is the same. The connection period may include four connection units, P=4, W=2. The first part includes two connection units, and the second part includes two connection units. In one of the first part and the second part, the second column data line D2 and the third column data line D3 in one connection unit CU1 are both connected to the first transfer line 11, and the first column data line D5 and the fourth column data line D8 in another connection unit CU2 are both connected to the first transfer line 11; in the other of the first part and the second part, the third column data line D11 and the fourth column data line D12 in one connection unit CU3 are both connected to the first transfer line 11, and the first column data line D13 and the second column data line D14 in another connection unit CU4 are both connected to the first transfer line 11.

[0126] The positions of the connection unit CU1 and the connection unit CU2 in the first part can be interchanged, and the positions of the connection unit CU3 and the connection unit CU4 in the second part can be interchanged.

[0127] In one embodiment, the connection unit CU1, the connection unit CU2, the connection unit CU3, and the connection unit CU4 can be arranged in sequence along the first direction, so that the second column data line D2 and the third column data line D3 in the first connection unit CU1 are both connected to the first adapter line 11, the first column data line D5 and the fourth column data line D8 in the second connection unit CU2 are both connected to the first adapter line 11, the third column data line D11 and the fourth column data line D12 in the third connection unit CU3 are both connected to the first adapter line 11, and the first column data line D13 and the second column data line D14 in the fourth connection unit CU4 are both connected to the first adapter line 11. The remaining data lines D are all connected to the second adapter line 12.

[0128] Figure 11 for Figure 4 The schematic diagram of the planar structure of the technical solution in one embodiment is shown. Figure 11 Only the first metal layer M1 and the second metal layer M2 are shown. Figure 11 As shown, the data line D and the first adapter line 11 can be arranged on the same layer, and both the data line D and the first adapter line 11 can be located in the second metal layer M2, and the second adapter line 12 can be located in the first metal layer M1. The display panel can include thin film transistors, and the data line D and the first adapter line 11 can be arranged on the same layer as the source and drain electrodes of the thin film transistors, and the second adapter line 12 can be arranged on the same layer as the gate electrode of the thin film transistor.

[0129] In other embodiments, the data line D may be provided on the same layer as the second adapter line 12. For example, the data line D and the second adapter line 12 may both be provided on the first metal layer M1. The data line D and the second adapter line 12 may be provided on the same layer as the source and drain of the thin film transistor, and the first adapter line 11 may be provided on the same layer as the gate of the thin film transistor.

[0130] Figure 11 for Figure 4 The partial schematic diagram of the technical solution shown in the actual product is Figure 4 The technical solution product shown is tested and compared with the product using the M1 / M2 / M1 / M2 related technology (i.e. the first adapter cable is only connected to the even-numbered column data lines). The half-frequency flicker of the product using the M1 / M2 / M1 / M2 related technology (i.e. the first adapter cable is only connected to the even-numbered column data lines) is 40dB at L63 grayscale and -46dB at L127 grayscale. Figure 4The half-frequency flicker of the products of the solution is 51dB at the L63 grayscale and -66dB at the L127 grayscale. It can be seen that the solution of the present disclosure improves the problem of poor half-frequency flicker results, and the improvement effect of half-frequency flicker is obvious.

[0131] like Figure 2-Figure 11 As shown, the display panel may further include an intermediate routing area MA located between the display area AA and the fan-shaped routing area FA. The data line D is located on the second metal layer M2, arranged on the same layer as the first adapter line 11, and on a different metal layer from the second adapter line 12. Therefore, the second adapter line 12 can be connected to the corresponding data line D through a first via located in the intermediate routing area MA.

[0132] like Figure 2-Figure 10 As shown, the display panel may further include multiple touch signal lines TX and multiple touch adapter lines. The touch signal lines TX extend along a first direction in the display area AA, and the multiple touch signal lines TX are sequentially arranged along a second direction in the display area AA. At least a portion of the touch adapter lines is located in the fan-out area FA.

[0133] refer to Figure 2-Figure 10 As shown in the cross-sectional view in FIG, the display panel further includes a first conductive layer M3, which is located on the same side as the first metal layer M1 and the second metal layer M2. A second insulating layer 22 is provided between the first conductive layer M3, the first metal layer M1, and the second metal layer M2. The touch signal line TX and the touch adapter line are both located in the first conductive layer M3. The touch adapter line is connected to two adjacent touch signal lines TX among the multiple touch signal lines TX; alternatively, the multiple touch adapter lines are connected to the multiple touch signal lines TX in a one-to-one correspondence. For example, the first metal layer M1 can be formed on a side surface of the substrate 20.

[0134] Figure 12 FIG. 1 is a schematic diagram of a display area in a display panel according to an embodiment of the present disclosure. Figure 12 As shown, the number of touch signal lines TX and data lines D is the same, and each touch signal line TX and a data line D are located between two adjacent columns of sub-pixels SP. Two adjacent touch signal lines TX can be connected to the same touch adapter line, such as Figure 2-Figure 10 As shown, in the middle wiring area MA, a touch signal line TX is provided between every two adjacent data lines D, and a data line D is provided between every two adjacent touch signal lines TX.

[0135] It should be noted that, in the embodiment of the present disclosure, the touch signal line TX and the touch adapter line adopt a separate conductive layer, and are no longer arranged on the same layer as the data line D, so the touch adapter line can be arranged more flexibly.

[0136] Figure 13FIG. 1 is a schematic diagram of a display area in a display panel according to another embodiment of the present disclosure. Figure 13 As shown, the ratio of the number of touch signal lines TX to the number of data lines D is 1:3, that is, one touch signal line TX is set for every three data lines D, and the touch signal line TX can be set with one data line D among the corresponding three data lines D between two adjacent columns of sub-pixels SP. Figure 13 In the embodiment, the touch signal line TX and the third data line D among the corresponding three data lines D are arranged between two adjacent columns of sub-pixels Sp.

[0137] Exemplarily, the material of the first conductive layer M3 may be a metal material, or may be a transparent conductive material, such as at least one of indium tin oxide (ITO) and indium zinc oxide (IZO).

[0138] Figure 14 for Figure 11 AA cross-sectional schematic diagram in one embodiment, as Figure 14 As shown, the first conductive layer M3 may further include a connecting line 231. The first via hole K1 includes a first portion and a second portion. The first portion penetrates the second insulating layer 22 to expose the data line D1, and the second portion penetrates the second insulating layer 22 and the first insulating layer 21 to expose the second patch line 12a. The connecting line 231 is connected to the data line D1 through the first portion of the first via hole K1, and is connected to the second patch line 12a through the second portion of the first via hole K1. Thus, the data line D1 and the second patch line 12a are connected via the connecting line 231.

[0139] In an exemplary embodiment, the first insulating layer 21 and the second insulating layer 22 may be made of any one or more of silicon oxide (SiOx), silicon nitride (SiNx), and silicon oxynitride (SiON), and may be a single layer, a multilayer, or a composite layer. The first metal layer M1, the second metal layer M2, and the first conductive layer M3 may be made of metal materials, such as any one or more of silver (Ag), copper (Cu), aluminum (Al), titanium (Ti), and molybdenum (Mo), or alloys of the above metals, such as aluminum neodymium alloy (AlNd) or molybdenum niobium alloy (MoNb), and may be a single layer structure or a multilayer composite structure, such as Ti / Al / Ti.
