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 the excellent performance of 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-quality display and high refresh rate, but also can achieve ultra-long battery life through dynamic frequency modulation, meeting users' demand for high-end notebooks.

[0057] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, 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 arbitrarily without conflict. Therefore, the drawings and descriptions are considered to be 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 at 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 a plurality of data lines D, but also provided with a plurality of touch signal lines TX. The display panel also includes a binding area (not shown in the figure) located at 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 more signal lines in the fan-shaped routing area FA.

[0059] In the related art, the fan-shaped wiring area FA adopts a double-layer wiring setting, and the fan-shaped wiring area FA is provided with a first metal layer M1 and a second metal layer M2, and a first insulating layer 21 is provided between the two metal layers. The touch switch wires are all provided in the second metal layer M2, a part of the data switch wires are provided in the first metal layer M1, and a part of the data switch wires are provided in the second metal layer M2.

[0060] For example, in Figure 1In the example, four columns of data lines D are used as 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 the four columns of data lines are M1 / M2 / M1 / M1 in sequence. In other words, among every four columns of data lines D, there is an even-numbered data line D corresponding to the data transfer line located in the second metal layer M2, or, among every four columns of data lines D, there is an even-numbered data line D 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 wiring area MA. Figure 1 In the embodiment, the first column data line D1, the third column data line D3 and the fourth column data line D4 are connected to the corresponding data adapter line through vias respectively; the second column data line D2 and the corresponding data adapter line are located in the same metal layer, so the second column data line D2 and the corresponding data adapter line are directly connected in the second metal layer M2. Every four columns of data lines D are connected to the corresponding data adapter line in the manner described in the above connection cycle.

[0062] Figure 1 In the figure, 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 line DO, and a negative voltage is provided to the even-numbered data line DE; or a positive voltage + is provided to the even-numbered data line DE, and a negative voltage is provided to the odd-numbered data line DO. The positive voltage and the negative voltage here are both relative to the common electrode voltage. The positive voltage is greater than the voltage of the common electrode, and the negative voltage is less than the voltage of the common electrode. 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 from Table 1, the odd-numbered data lines DO are provided with a positive voltage +, and the even-numbered data lines DE are provided with a negative voltage -. Among the even-numbered data lines DE, the data transfer lines corresponding to the second-numbered data lines D2 and the sixth-numbered data lines D6 are located in the second metal layer M2, and the data transfer lines corresponding to the other data lines D are located in the first metal layer M1; among the odd-numbered data lines DO, the data transfer lines corresponding to all the data lines D are located in the first metal layer M1. That is to say, among the even-numbered data lines DE, the second-numbered data lines D2 and the sixth-numbered data lines D6 are driven by the data transfer lines of the second metal layer M2, and the other data lines D are driven by the data transfer lines of the first metal layer M1, while the odd-numbered data lines DO are all driven by the data transfer lines of the first metal layer M1.

[0068] The difference in film layer process in the display panel leads to different resistances of data adapters in different metal layers, and different connection resistances between different data adapters 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 of the second metal layer M2, and other data lines D are driven by the data adapter of the first metal layer M1, the influence of the data adapter of the second metal layer M2 on the even column data line DE and the odd column data line DO is unbalanced, which leads to uneven driving of the odd column data line DO and the even column data line DE, or uneven pulling of the odd and even columns. In addition, the line width of the data adapter of the second metal layer M2 and the line width of the data adapter of the first metal layer M1 cannot meet the design requirements in terms of process control, which further leads to 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, ..., an odd Arabic numeral indicates that the data line is an odd-numbered data line, and an even Arabic numeral indicates 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 Both show the data line D and the corresponding data transfer line in a part of the display panel. Figure 2-Figure 10As shown, the display panel includes a display area AA and a fan-shaped wiring area FA located on one side of the display area AA along a first direction. The display panel includes a plurality of data lines D and a plurality of data transfer lines. The data lines D extend along a first direction in the display area AA, and the plurality of data lines D are arranged in sequence along a second direction in the display area AA. The second direction intersects the first direction, for example, the second direction may 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. The plurality of data transfer lines are connected to the plurality of data lines D in a one-to-one correspondence, and at least part of the data transfer lines is located in the fan-shaped routing area FA. In the fan-shaped routing area FA, the plurality of data transfer lines can be routed in a fan-shaped shape.

[0072] The plurality of data transfer lines may include a plurality of first transfer lines 11 and a plurality of second transfer lines 12. The display panel includes a first metal layer M1 and a second metal layer M2, and a first insulating layer 21 is provided 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 the first transfer lines 11 is less than or equal to one half of the number of the 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 one by one, and the other data lines D are connected to the corresponding second adapter lines 12.

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

[0075] The display panel may further include an intermediate wiring area MA between the display area AA and the fan-shaped wiring area FA. The data transfer line on the same layer as the data line D may be connected to the data line D through the same layer of metal in the intermediate wiring area MA, and the data transfer line on a different layer from the data line D may be connected to the data line D through a via in the intermediate wiring area MA.

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

[0077] The technical solution of the embodiment of the present disclosure is to set at least one first adapter line 11 to be connected to the even-numbered data lines DE, and at least one first adapter line 11 to be connected to the odd-numbered data lines DO, so that at least one of the odd-numbered data lines DO is 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 is connected to the first adapter line 11 located in the second metal layer M2, thereby avoiding that 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 with the related art, the technical solution of the present disclosure improves the problem of uneven influence of the first adapter line 11 on the odd-numbered data lines DO and the even-numbered data lines DE, so that when half-frequency driving is adopted, uneven driving of the odd-numbered data lines DO and the even-numbered data lines DE can be improved, 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 effect of the display panel at low frequency can be improved.

[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 plan 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 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 the first adapter lines 11 can be an even number, and one half of the multiple first adapter lines 11 are connected to the even-numbered column data lines DE, and the other half are connected to the odd-numbered column data lines DO. In this configuration, the number of the even-numbered column data lines DE and the odd-numbered column data lines DO connected to the first adapter lines 11 is the same, which further improves the problem of 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 adopted, the uneven driving of the odd-numbered column data lines DO and the even-numbered column data lines DE can be further improved, the uneven pulling of the odd and even columns can be improved, and the problem of poor half-frequency Flicker results can be improved.

[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 a plurality of connection periods along the second direction. Figure 2A connection cycle in one embodiment is shown in FIG. Figure 3 A connection cycle in another embodiment is shown in FIG. Figure 4-Figure 7 A connection cycle in different embodiments is shown respectively. Figure 8-Figure 10 A connection period in different embodiments is shown respectively. It can be understood that the display panel can be set 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, and illustratively, 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 one-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 adapter lines and the corresponding data lines in different connection cycles is the same, the film layer where the corresponding data adapter 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 the connection wiring for a large number of data lines D and data adapter 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 adapter line in the middle routing area MA, which facilitates the connection wiring of a large number of data lines D and data adapter lines and improves the wiring design efficiency.

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

[0084] By setting 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 can be achieved that at least one even-numbered data line DE is connected to the first adapter line 11 in each connection cycle, and at least one odd-numbered data line DO is coupled to the first adapter line 11, so as to improve the problem of 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 ​​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 better 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 8 data transfer lines include two first transfer lines 11. The first transfer line 11a of the two first transfer lines 11 is connected to the second column data line D2, and the second column data line D2 is the even column data line DE; the other first transfer line 11b of the two first transfer lines 11 is connected to the seventh column data line D7, and the seventh column data line D7 is the odd column data line DO. The data transfer lines other than the first transfer lines 11 are second transfer lines 12, for example, the second transfer lines 12 include second transfer lines 12a, 12b, 12c, 12d, 12e, and 12f, and these second transfer lines 12 are connected to the data lines D1, D3, D4, D5, D6, and D8 in a one-to-one correspondence.

[0087] For example, Figure 3In the embodiment, M=16, N=4, two first adapters 11a and 11c are respectively connected to the 1st column data line D1 and the 11th column data line D11, which are odd-numbered column data lines DO; the other two first adapters 11b and 11c are respectively coupled to the 6th column data line D6 and the 16th column data line D16, which are even-numbered column data lines DE. The data adapters other than the first adapters 11 are second adapters 12, which are connected one by one to the corresponding data lines D.

[0088] Figure 4-Figure 10 The same is true for the corresponding embodiments, which are not listed one by one here.

[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 problem of 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 switching lines 11 are arranged symmetrically among the M data lines D. For example, Figure 2 In the figure, one connection cycle includes two first adapters 11, the first adapter 11a corresponds to the data line D2, the first adapter 11b corresponds to the data line D7, and the data line D2 and the data line D7 are arranged symmetrically in the 8 data lines. The data adapters corresponding to the data line D2 and the data line D7 are both the first adapters 11, and the other data adapters are the second adapters 12. The first adapter 11 is located in the second metal layer M2, and the second adapter 12 is located in the first metal layer M1. Therefore, the film layer arrangement positions of the 8 data adapters are M1 / M2 / M1 / M1|M1 / M1 / M2 / M1. It can also be seen from the arrangement position that the data lines D corresponding to the two first adapters 11 are arranged in the 2nd column and the 7th column in the M data lines D, respectively, and the two arrangement positions are symmetrical.

[0091] In the embodiment of the present disclosure, by setting the arrangement position of each first adapter line 11 in the M data lines D to be symmetrical, the influence of the first adapter line 11 on the odd-column data lines DO and the even-column data lines DE in the corresponding area of ​​the connection period is also symmetrical. Therefore, the influence of the first adapter line 11 on the odd-column data lines DO and the even-column data lines DE is balanced, which can improve the problem of poor half-frequency Flicker results in the corresponding area of ​​each connection period to a greater extent.

[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 respectively located at the 1st position, the 6th position, the 11th position and the 16th position, 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 the embodiment, one connection cycle includes 4 data lines D and 4 data adapter lines. The arrangement positions of the 4 data adapter lines in the 4 data lines D are M2 / M1 / M1 / M2. From the arrangement positions, it can be seen that the two first adapter lines 11 are respectively located at the 1st position and the 4th position, and the arrangement positions of these two positions are symmetrical.

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

[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 is connected to the even-numbered data line DE, and at least two of 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 is connected to the odd-numbered column data line DO, and at least one first adapter line 11 is connected to the even-numbered column data line DE, which facilitates the wiring design.

[0098] For example, Figure 4 In the embodiment, the data adapter wires corresponding to the data line D2 and the data line D3 are both first adapter wires 11, and the two first adapter wires 11 are connected to the adjacent second column data line D and third column data line D in one-to-one correspondence. Figure 5In the embodiment, the data adapter wires corresponding to the data lines D1 and D2 are two first adapter wires 11, and the two first adapter wires 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 the data lines 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 the data lines 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, and 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. The data lines D corresponding to at least one first transfer line 11 in each connection unit have different arrangement positions 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 the embodiment, the connection cycle includes two connection units, P=4, W=1. In the first connection unit, the second column data line D2 is connected to the first adapter line 11a; in the second connection unit, the third column data line D3 is connected to the first adapter line 11b. The data lines D corresponding to the first adapter line 11 in the two connection units are the second column and the third column, respectively, and the arrangement positions are different.

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

[0104] Figure 8 In the embodiment, the connection cycle includes two connection units, P=4, 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. The data lines D corresponding to the first adapter line 11 in the two connection units are arranged in different positions, namely, the first and third columns, and the first and fourth columns.

[0105] Fig. 9 In the embodiment, the connection cycle includes two connection units, P=4, W=2. In the first connection unit, the data lines D in the 3rd and 4th columns are both connected to the first adapter line 11; in the second connection unit, the data lines D in the 1st and 2nd columns are both connected to the first adapter line 11. The data lines D corresponding to the first adapter line 11 in the two connection units are arranged in different positions, namely, the 3rd and 4th columns, and the 2nd and 3rd columns.

[0106] Fig.10 In the embodiment, the connection cycle includes four connection units, P=4, 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; 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 the second and third columns, the first and fourth columns, the third and fourth columns, and the first and second columns, respectively, and the arrangement positions of the data lines D corresponding to at least one first adapter line 11 in the four connection units are different.

[0107] It should be noted that Figure 8 , Fig. 9 , Fig.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. Fig.10 The arrangement positions of the four connection units can be set as needed.

[0108] Such a setting 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 unbalanced 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 may be an even number, and one half of the W first switching 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 , Fig. 9 and Fig.10 In the embodiment, each connection unit has two first switching lines 11 , wherein one first switching line 11 is connected to the even-numbered data lines DE, and the other first switching line 11 is connected to the odd-numbered data lines DO.

[0110] In one embodiment, the connection period includes a first part and a second part along the second direction, and the number of connection units in the first part and the second part is the same. The data lines D corresponding to the first adapter lines 11 in each connection unit of the first part are arranged in different positions in the connection unit. The data lines D corresponding to the first adapter lines 11 in each connection unit of the second part are arranged in different positions in 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 adapter 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 adapter line 11 in the connection unit in the second part. Figure 8 and Fig. 9 shown.

[0112] For example, Figure 8In the embodiment, the first part includes a connection unit, and the second part includes a 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 column and the third column 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 column and the fourth column respectively.

[0113] Fig. 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. The data lines D corresponding to the first adapter lines 11c and 11d in the second part of the connection unit 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 adapter 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 adapter line 11 in each connection unit of the second part. Fig.10 shown.

[0115] exist Fig.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 column and the third column, and in the first column and the fourth column, respectively, and 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 data lines D corresponding to the first adapter lines 11 in the two connection units are arranged in different positions in the connection units.

[0117] It can be seen that the data lines D corresponding to the first adapter line 11 in the first part are arranged in the second and third columns, and the first and fourth columns in the connection unit; the data lines D corresponding to the first adapter line 11 in the second part 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 adapter line 11 in the first part and the data lines D corresponding to the first adapter line 11 in the second part are the same, which are 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.

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 another 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.

The arrangement order of the two connection units in the second direction can be set as needed, for example, for example, Fig. 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 adapter line 11a; the second column data line D6 in the second connection unit CU2 is connected to the first adapter line 11b; the third column data line D11 in the third connection unit CU3 is connected to the first adapter line 11c; the fourth column data line D16 in the fourth connection unit CU4 is connected to the first adapter line 11d. The arrangement positions of the four connection units in the second direction can be set as needed.

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

[0125] In one embodiment, reference Fig.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 adapter 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 adapter line 11; in another 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 adapter 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 adapter 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 other data lines D are all connected to the second adapter line 12.

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

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

[0130] Fig.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 was tested and compared with the product using the M1 / M2 / M1 / M2 (i.e. the first adapter cable is only connected to the even-numbered data lines) technology. The half-frequency flicker of the product using the M1 / M2 / M1 / M2 (i.e. the first adapter cable is only connected to the even-numbered data lines) technology was 40dB for the L63 grayscale and -46dB for the 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 between the display area AA and the fan-shaped routing area FA. The data line D is located in the second metal layer M2, and is arranged in the same layer as the first adapter line 11, and is located in 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 hole, and the first via hole is located in the intermediate routing area MA.

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

The touch adapter line is connected to two adjacent touch signal lines TX among the multiple touch signal lines TX; or, the multiple touch adapter lines are connected to the multiple touch signal lines TX in a one-to-one correspondence. Exemplarily, the first metal layer M1 can be formed on a surface of one side of the substrate 20.

[0134] Fig.12 FIG. 1 is a schematic diagram of a display area in a display panel according to an embodiment of the present disclosure. Fig.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.

[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 in the same layer as the data line D, so the touch adapter line can be arranged more flexibly.

[0136] Fig.13FIG. 1 is a schematic diagram of a display area in a display panel according to another embodiment of the present disclosure. Fig.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 provided for every three data lines D, and the touch signal line TX can be provided with one data line D among the corresponding three data lines D between two adjacent columns of sub-pixels SP. Fig.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).

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 adapter line 12a through the second portion of the first via hole K1, so that the data line D1 and the second adapter line 12a are connected through 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 alloy materials 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, etc.
