Summary of the Invention

[0004] An embodiment of the present application provides a display panel and a terminal device, which can reduce the border width of the side of the display panel bound to the driver chip while sequentially changing the input first display data through the driver chip so that the second display data obtained after the change can be transmitted to the correct signal line.

[0005] In a first aspect, an embodiment of the present application proposes a display panel, which has a display area and a frame area surrounding the display area, the frame area including a fan-out area and a binding area, and the fan-out area is located between the binding area and the display area; the display area includes a first edge display area, a center display area, and a second edge display area, each of which is provided with a signal line extending along a first direction, and the first edge display area, the center display area, and the second edge display area are distributed in sequence along a second direction, and the first direction intersects with the second direction; a plurality of first connecting lines and a plurality of second connecting lines are further provided in the display area, one end of each first connecting line extends to the first edge display area and the other end extends to the center display area, and one end of each second connecting line extends to the second edge display area and the other end extends to the center display area; a plurality of fan-out leads are provided in the fan-out area, and a signal line bound to the fan-out leads is provided in the binding area. A driver chip, wherein signal lines in a first edge display area are connected to fan-out leads via first connecting lines, signal lines in a second edge display area are connected to fan-out leads via second connecting lines, and signal lines in a central display area are also connected to fan-out leads; wherein the driver chip includes a sequence change module, the sequence change module being configured to sequentially change first display data in a first display data sequence corresponding to each input signal line according to a first correspondence between an arrangement number of each fan-out lead and an arrangement number of a signal line connected thereto, thereby obtaining a second display data sequence, and outputting second display data in the second display data sequence to each fan-out lead; a second correspondence exists between the arrangement number of the signal line corresponding to the first display data and the arrangement number of the signal line corresponding to the second display data at the same position number, and the first correspondence is the same as the second correspondence.

[0006] The position number refers to the position number of the display data in the corresponding display data sequence, and the arrangement number refers to the order number of the signal line and the fan-out lead along the same direction. In this way, in the embodiment of the present application, one end of the first connecting line is connected to the signal line located in the first edge display area, and the other end of the first connecting line extends to the central display area, and one end of the second connecting line is connected to the signal line located in the second edge display area, and the other end of the second connecting line extends to the central display area, so that the fan-out leads are distributed in the area extending along the first direction of the central display area within the fan-out area, thereby reducing the border width of the first side of the display panel; in addition, the driver chip sequentially changes the input first display data according to the first corresponding relationship between the arrangement number of each fan-out lead and the arrangement number of the signal line connected to it, so that each second display data obtained after the change can be transmitted to the correct signal line, so that the display panel displays normally. In addition, the driver chip in the embodiment of the present application can be applied to different types of terminal devices. Therefore, the same driver chip can be used for different terminal devices, thereby improving the utilization rate of the driver chip and reducing the design cost of the driver chip.

[0007] In an optional embodiment, each second display data in the second display data sequence is divided into a first change data set, a second change data set, a third change data set and a fourth change data set in ascending order of position numbers, and the first change data set, the second change data set, the third change data set and the fourth change data set all include multiple second display data; the change pattern of the arrangement sequence numbers of the signal lines corresponding to each second display data in the first change data set is different from the change pattern of the arrangement sequence numbers of the signal lines corresponding to each second display data in the second change data set; the change pattern of the arrangement sequence numbers of the signal lines corresponding to each second display data in the fourth change data set is different from the change pattern of the arrangement sequence numbers of the signal lines corresponding to each second display data in the third change data set. In this way, the embodiment of the present application can insert the first display data in the first data set and the fourth data set between the starting insertion position number and the ending insertion position number to sequentially change the first display data in the first display data sequence corresponding to each input signal line to obtain the second display data sequence, so that the second display data sequence is divided into the first change data set, the second change data set, the third change data set and the fourth change data set according to the different change rules between each second display data.

[0008] In an optional implementation manner, the second display data in the first change data set is the first change data, and the arrangement sequence numbers of the signal lines corresponding to the respective first change data are increased in sequence according to the position sequence numbers of the respective first change data from small to large; the second change data set includes at least one first change data combination, and the second display data in each first change data combination are the second change data and the third change data, and the arrangement sequence numbers of the signal lines corresponding to the respective second change data are increased in sequence according to the position sequence numbers of the respective second change data from small to large. Within the same first change data combination, the arrangement sequence number of the signal line corresponding to the third change data is smaller than the arrangement sequence number of the signal line corresponding to the second change data, the second change data is the second display data input to the signal line in the central display area, and the third change data is the second display data input to the signal line in the first edge display area. display data; the third change data set includes at least one second change data combination, the second display data in each second change data combination being the fourth change data and the fifth change data, the arrangement sequence numbers of the signal lines corresponding to the respective fourth change data being incremented in ascending order of the position sequence numbers of the respective fourth change data, within the same second change data combination, the arrangement sequence numbers of the signal lines corresponding to the fifth change data being greater than the arrangement sequence numbers of the signal lines corresponding to the fourth change data, the fourth change data being the second display data input to the signal lines in the center display area, and the fifth change data being the second display data input to the signal lines in the second edge display area; the second display data in the fourth change data set being the sixth change data, the arrangement sequence numbers of the signal lines corresponding to the respective sixth change data being incremented in ascending order of the position sequence numbers of the respective sixth change data. In this way, the sequential change method for the driver chip to sequentially change the first display data sequence to obtain the second display data sequence is simplified, and accordingly, the signal lines corresponding to the first change data and the sixth change data only need to be connected to the corresponding fan-out leads in their arrangement order, thereby simplifying the connection relationship between the signal lines and the fan-out leads in the display panel.

[0009] In an optional embodiment, the absolute value of the difference between the arrangement numbers of the signal lines corresponding to two adjacent first change data is 1; and the absolute value of the difference between the arrangement numbers of the signal lines corresponding to two adjacent sixth change data is 1. In this case, the driver chip only needs to increase the arrangement numbers of the signal lines corresponding to each first change data in the first change data set in sequence according to the position number of the signal line, and increase the arrangement numbers of the signal lines corresponding to each sixth change data in the fourth change data set in sequence according to the position number of the signal line, thereby reducing the complexity of the driver chip in sequentially changing the first display data sequence.

[0010] In an optional implementation manner, the number of the first change data in the first change data set is equal to the number of the sixth change data in the fourth change data set.

[0011] In an optional implementation, the number of first change data combinations included in the second change data set is equal to the number of second change data combinations included in the third change data set; the number of second change data included in each first change data combination is equal, and the number of third change data included in each first change data combination is equal; the number of fourth change data included in each second change data combination is equal, and the number of fifth change data included in each second change data combination is equal; and the number of second change data included in the first change data combination is equal to the number of fourth change data included in the second change data combination, and the number of third change data included in the first change data combination is equal to the number of fifth change data included in the second change data combination. In this way, the number of first display data that needs to be inserted in the first data set and the fourth data set can be equal, that is, the number of signal lines in the first edge display area and the second edge display area is equal, so as to maximize the reduction of the border width on the first side of the display panel; if the number of signal lines in the first edge display area and the second edge display area is not equal, the border width on the first side of the display panel is mainly affected by the fan-out leads connected to the signal lines in the edge display area with a smaller number of signal lines. When the number of signal lines in the edge display area is smaller, the reduction in the border width on the first side of the display panel is lower, resulting in the inability to minimize the border width on the first side of the display panel.

[0012] In an optional embodiment, within the same first change data combination, the difference between the arrangement number of the signal line corresponding to the second change data and the arrangement number of the signal line corresponding to the third change data is greater than 1; within the same second change data combination, the difference between the arrangement number of the signal line corresponding to the fifth change data and the arrangement number of the signal line corresponding to the fourth change data is greater than 1.

[0013] In an optional embodiment, the second change data set includes multiple first change data combinations, and the difference between the arrangement number of the signal line corresponding to the second change data with the smallest position number in the m+1th first change data combination and the arrangement number of the signal line corresponding to the second change data with the largest position number in the mth first change data combination is 1; the third change data set includes multiple second change data combinations, and the difference between the arrangement number of the signal line corresponding to the fourth change data with the smallest position number in the m+1th second change data combination and the arrangement number of the signal line corresponding to the fourth change data with the largest position number in the mth second change data combination is 1; wherein m is a positive integer, the position number of each second change data in the m+1th first change data combination is greater than the position number of the second change data in the mth first change data combination, and the position number of each fourth change data in the m+1th second change data combination is greater than the position number of the fourth change data in the mth second change data combination. In this way, according to the order of the position numbers of each second change data from small to large, the arrangement numbers of the signal lines corresponding to each second change data are increased in sequence, and according to the order of the position numbers of each fourth change data from small to large, the arrangement numbers of the signal lines corresponding to each fourth change data are increased in sequence, which further makes it simpler for the driver chip to sequentially change the first display data sequence to obtain the second display data sequence.

[0014] In an optional embodiment, each first change data combination includes multiple second change data, and within the same first change data combination, the difference between the arrangement number of the signal line corresponding to the z+1th second change data and the arrangement number of the signal line corresponding to the zth second change data is 1; each second change data combination includes multiple fourth change data, and within the same second change data combination, the difference between the arrangement number of the signal line corresponding to the z+1th fourth change data and the arrangement number of the signal line corresponding to the zth fourth change data is 1; wherein z is a positive integer, the difference between the position number of the z+1th second change data and the position number of the zth second change data is 1, and the difference between the position number of the z+1th fourth change data and the position number of the zth fourth change data is also 1. In this way, within the same first change data combination, the arrangement numbers of the signal lines corresponding to the second change data are incremented in ascending order according to the position numbers thereof. Within the same second change data combination, the arrangement numbers of the signal lines corresponding to the fourth change data are also incremented in ascending order according to the position numbers thereof. This further simplifies the sequential change method for the driver chip to sequentially change the first display data sequence to obtain the second display data sequence.

[0015] In an optional embodiment, each first change data combination includes multiple third change data, and within the same first change data combination, the difference between the arrangement sequence number of the signal line corresponding to the rth third change data and the arrangement sequence number of the signal line corresponding to the r+1th third change data is 1; each second change data combination includes multiple fifth change data, and within the same second change data combination, the difference between the arrangement sequence number of the signal line corresponding to the rth fifth change data and the arrangement sequence number of the signal line corresponding to the r+1th fifth change data is 1; wherein r is a positive integer, the difference between the position sequence number of the r+1th third change data and the position sequence number of the rth third change data is 1, and the difference between the position sequence number of the r+1th fifth change data and the position sequence number of the rth fifth change data is also 1. In this way, the embodiment of the present application provides a distribution method of the arrangement sequence numbers of the signal lines corresponding to the third change data in the same first change data combination from large to small, and a distribution method of the arrangement sequence numbers of the signal lines corresponding to the fifth change data in the same second change data combination from large to small.

[0016] In an optional embodiment, each first change data combination includes multiple third change data, and within the same first change data combination, the difference between the arrangement sequence number of the signal line corresponding to the r+1th third change data and the arrangement sequence number of the signal line corresponding to the rth third change data is 1; each second change data combination includes multiple fifth change data, and within the same second change data combination, the difference between the arrangement sequence number of the signal line corresponding to the r+1th fifth change data and the arrangement sequence number of the signal line corresponding to the rth fifth change data is 1; wherein r is a positive integer, the difference between the position sequence number of the r+1th third change data and the position sequence number of the rth third change data is 1, and the difference between the position sequence number of the r+1th fifth change data and the position sequence number of the rth fifth change data is also 1.

[0017] In an optional embodiment, the second change data set includes multiple first change data combinations, and the difference between the minimum value of the arrangement sequence number of the signal line corresponding to each third change data in the mth first change data combination and the maximum value of the arrangement sequence number of the signal line corresponding to each third change data in the m+1th first change data combination is 1; the third change data set includes multiple second change data combinations, and the difference between the minimum value of the arrangement sequence number of the signal line corresponding to each fifth change data in the mth second change data combination and the maximum value of the arrangement sequence number of the signal line corresponding to each fifth change data in the m+1th second change data combination is 1; wherein m is a positive integer, the position sequence number of each third change data in the m+1th first change data combination is greater than the position sequence number of the third change data in the mth first change data combination, and the position sequence number of each fifth change data in the m+1th second change data combination is greater than the position sequence number of the fifth change data in the mth second change data combination.

[0032] To facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. For example, the first chip and the second chip are merely used to distinguish different chips and do not limit their order. Those skilled in the art will understand that the words "first" and "second" do not limit the quantity or execution order, and the words "first" and "second" do not necessarily mean that they are different.

[0033] It should be noted that in the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0034] In the embodiments of the present application, "at least one" refers to one or more, and "more" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, c can be single or multiple.

[0035] In related technologies, such as Figure 1 As shown, the display panel 10 includes a display area 11 and a frame area 12 surrounding the display area 11 . The frame area 12 includes a fan-out area and a binding area arranged on a first side of the display area 11 . The fan-out area is located between the binding area and the display area.

[0036] Signal lines 111 extending in a first direction Y are provided within the display area 11. These signal lines 111 are data lines. A driver chip 122 is provided within the bonding area. Because the driver chip 122 is smaller in a second direction X than the display area 11, and the second direction X is the row direction of the display panel 10, multiple fan-out leads 121 are provided within the fan-out area to connect the driver chip 122 to the signal lines 111.

[0037] In some products, the driver chip 122 is bound to the binding area of ​​the display panel 10 using a chip on film (COF) 123. A connecting trace is provided on the COF 123, one end of which is connected to the pin of the driver chip 122, and the other end of which is connected to the binding terminal (not shown) of the COF 123. The fan-out lead 121 is actually connected to the binding terminal of the COF 123, thereby realizing the connection between the fan-out lead 121 and the driver chip 122 based on the COF 123. Therefore, the display data provided by the driver chip 122 is output from the pin of the driver chip 122, transmitted to the signal line 111 through the connecting trace of the COF 123, the binding terminal of the COF 123, and the fan-out lead 121, and then transmitted to the pixel driving circuit in the same column through the signal line 111.

[0038] Of course, it is understandable that the driver chip 122 is not limited to being bound to the binding area of ​​the display panel using COF. It can also use COG (chip on glass) or COP (chip on plastic). COG refers to the use of anisotropic conductive adhesive to directly bind the driver chip to the display panel, and the substrate of the display panel is a glass substrate, while COP refers to directly fixing the driver chip to the display panel using a plastic substrate, which is suitable for flexible display panels.

[0039] In practice, the display area 11 includes a first edge, a second edge, a third edge, and a fourth edge, which are sequentially connected end to end. The first edge and the second edge are disposed opposite each other, and the third edge and the fourth edge are disposed opposite each other. The third edge is disposed adjacent to the first and second edges, respectively, and the fourth edge is also disposed adjacent to the first and second edges, respectively. The first edge refers to the edge of the display area 11 facing the driver chip 122. In practice, the first corner CNT1 connects the first edge to the third edge, and the second corner CNT2 connects the first edge to the fourth edge. Both the first corner CNT1 and the second corner CNT2 are arc-shaped.

[0040] Therefore, when the signal line 111 is connected to the binding terminal of the chip-on-chip film 123 through the fan-out lead 121, the fan-out lead 121 connected to the signal line 111 near the third edge of the display area 11 needs to be routed from the first corner CNT1 to the position of the chip-on-chip film 123, and the fan-out lead 121 connected to the signal line 111 near the fourth edge of the display area 11 needs to be routed from the second corner CNT2 to the position of the chip-on-chip film 123.

[0041] Since the fan-out lead 121 has a certain line width and there is a certain distance between two adjacent fan-out leads 121, the arrangement of the fan-out lead 121 connected to the signal line 111 near the third edge of the display area 11 and the fan-out lead 121 connected to the signal line 111 near the fourth edge of the display area 11 will cause the border width d1 on the first side of the display panel 10 to be larger, and will also affect the rounded radii of the corners corresponding to the first corner CNT1 and the second corner CNT2 in the border area 12 of the display panel 10 (that is, the lower left corner of the border area 12 and the lower right corner of the border area 12), resulting in the inability to design the corner positions of the display panel 10 to the required radii.

[0042] In order to reduce the border width of the first side of the display panel 10 and improve the influence of the fan-out lead 121 on the rounded arc at the corner position of the border area 12, as shown in FIG. Figure 2 and Figure 3 As shown, the display panel 20 includes a display area 21 and a frame area 22 surrounding the display area 21. The display area 21 includes a first edge display area 212, a central display area 211 and a second edge display area 213 distributed in sequence along the second direction X. The central display area 211 is located between the first edge display area 212 and the second edge display area 213. The first edge display area 212 is located between the central display area 211 and the third edge of the display area 21. The second edge display area 213 is located between the central display area 211 and the fourth edge of the display area 21.

[0043] A signal line 31 extending along a first direction Y and a plurality of sub-pixels 32 distributed in an array are provided in the display area 21. Each sub-pixel 32 includes a pixel driving circuit and a light-emitting device connected to the pixel driving circuit. The pixel driving circuits in the same column are connected to the same signal line 31, which is a data line.

[0044] In practice, signal lines extending along a first direction Y are disposed in the first edge display area 212, the central display area 211, and the second edge display area 213 included in the display area 21. The first direction Y intersects with the second direction X. In some embodiments, the first direction Y and the second direction X are perpendicular to each other. The first direction Y is the column direction of the display panel 20, and the second direction X is the row direction of the display panel 20.

[0045] A first connecting line 33a and a second connecting line 33b are also provided in the display area 21 of the display panel 20. One end of the first connecting line 33a extends to the first edge display area 212 and is connected to the signal line 31 located in the first edge display area 212. The other end of the first connecting line 33a extends to the boundary of the first side of the central display area 211. One end of the second connecting line 33b extends to the second edge display area 213 and is connected to the signal line 31 located in the second edge display area 213. The other end of the second connecting line 33b extends to the boundary of the first side of the central display area 211.

[0046] The frame area 22 includes a fan-out area and a binding area located on the first side of the display area 21. The fan-out area is located between the binding area and the display area 21. A plurality of fan-out leads 41 are provided in the fan-out area. A driver chip 42 is provided in the binding area. The driver chip 42 is bound to the binding area through a chip-on-film 43. The fan-out leads 41 are connected to the driver chip 42 through the chip-on-film 43. Of course, the driver chip 42 can also be bound to the binding area of ​​the display panel 20 using COG or COP. For a detailed description, please refer to Figure 1 The description of the driver chip binding is not repeated here to avoid repetition.

[0047] The other end of the first connecting line 33a extends to the boundary of the first side of the central display area 211, and is connected to the fan-out lead 41 located in the fan-out area at the boundary of the first side of the central display area 211, that is, the signal line 31 in the first edge display area 211 is connected to the fan-out lead 41 through the first connecting line 33a; the other end of the second connecting line 33b extends to the boundary of the first side of the central display area 211, and is connected to the fan-out lead 41 located in the fan-out area at the boundary of the first side of the central display area 211, that is, the signal line 31 in the second edge display area 213 is connected to the fan-out lead 41 through the second connecting line 33b; and the signal line 31 in the central display area 211 is directly connected to the fan-out lead 41.

[0048] Therefore, the fan-out lead 41 can be distributed only in the area after the central display area 211 in the fan-out area extends along the first direction Y, and the fan-out lead 41 does not need to go around from the first corner CNT1 or the second corner CNT2 of the display area 21 to the position of the chip-on-film 43, thereby reducing the border width of the first side of the display panel 20; and the fan-out lead 41 will not excessively affect the radius of the corners corresponding to the first corner CNT1 and the second corner CNT2 in the border area 22 of the display panel 20, so that the corner position of the display panel 20 can be designed according to the required radius.

[0049] Among them, the first connecting line 33a and the second connecting line 33b can both include a first sub-segment, a second sub-segment and a third sub-segment connected in sequence, the first sub-segment extends along the first direction Y and is connected to the signal line 31, the second sub-segment extends along the second direction X, and the third sub-segment extends along the first direction Y and is connected to the fan-out lead 41. The first direction Y and the second direction X can be perpendicular to each other.

[0050] It is understood that the specific structures of the first connecting line 33a and the second connecting line 33b are not limited to Figure 2 The structure shown, as long as one end of the first connecting line 33a can extend to the first edge display area 212 and be connected to the signal line 31 located in the first edge display area 212, and the other end of the first connecting line 33a extends to the boundary of the first side of the central display area 211, and, one end of the second connecting line 33b can extend to the second edge display area 213 and be connected to the signal line 31 located in the second edge display area 213, and the other end of the second connecting line 33b extends to the boundary of the first side of the central display area 211.

[0051] For example, the first connecting line 33a and the second connecting line 33b may only include a second sub-segment and a third sub-segment that are connected to each other, the second sub-segment in the first connecting line 33a extends along the second direction X and is directly connected to the signal line 31 in the first edge display area 212, the third sub-segment in the first connecting line 33a extends along the first direction Y and extends to the boundary of the first side of the central display area 211, the second sub-segment in the second connecting line 33b extends along the second direction X and is directly connected to the signal line 31 in the second edge display area 213, and the third sub-segment in the second connecting line 33b extends along the first direction Y and extends to the boundary of the first side of the central display area 211.

[0052] Alternatively, the first connection line 33a and the second connection line 33b may include a fourth sub-segment and a fifth sub-segment connected to each other, the fourth sub-segment in the first connection line 33a is connected to the signal line 31 in the first edge display area 212, the fifth sub-segment in the first connection line 33a extends to the boundary of the first side of the central display area 211, and in the first connection line 33a, the fourth sub-segment and the fifth sub-segment each have an angle that is not zero with the first direction Y and the second direction X, that is, the fourth sub-segment in the first connection line 33a intersects the first direction Y and the second direction X, and the fifth sub-segment in the first connection line 33a intersects the first direction Y and the second direction X. The line segment also intersects with both the first direction Y and the second direction X; accordingly, the fourth sub-line segment in the second connecting line 33b is connected to the signal line 31 in the second edge display area 213, and the fifth sub-line segment in the second connecting line 33b extends to the boundary of the first side of the central display area 211, and in the second connecting line 33b, the fourth sub-line segment and the fifth sub-line segment each have a non-zero angle with the first direction Y and the second direction X, that is, the fourth sub-line segment in the second connecting line 33b intersects with both the first direction Y and the second direction X, and the fifth sub-line segment in the second connecting line 33b also intersects with both the first direction Y and the second direction X.

[0053] In addition, in the display area 21, the first connecting line 33a and the second connecting line 33b are arranged in the same layer, and the film layer where the signal line 31 is located is different from the film layer where the first connecting line 33a and the second connecting line 33b are located, that is, the signal line 31 and the first connecting line 33a are located in different film layers, and the signal line 31 and the second connecting line 33b are also located in different film layers; and, the film layer where the first connecting line 33a and the second connecting line 33b are located and the film layer where the signal line 31 is located are separated by at least one insulating layer, that is, at least one insulating layer is provided between the film layer where the first connecting line 33a and the second connecting line 33b are located and the film layer where the signal line 31 is located, and the first connecting line 33a and the second connecting line 33b are respectively connected to the signal line 31 through vias penetrating the insulating layer.

[0054] For example, in some embodiments, the first sub-segment in the first connecting line 33a is connected to the signal line 31 located in the first edge display area 212 through a via penetrating the insulating layer, and the first sub-segment in the second connecting line 33b is connected to the signal line 31 located in the second edge display area 213 through a via penetrating the insulating layer; in other embodiments, the fourth sub-segment in the first connecting line 33a is connected to the signal line 31 located in the first edge display area 212 through a via penetrating the insulating layer, and the fourth sub-segment in the second connecting line 33b is connected to the signal line 31 located in the second edge display area 213 through a via penetrating the insulating layer.

[0055] When the signal line 31 located in the first edge display area 212 is connected to the fan-out lead 41 through the first connecting line 33a, and the signal line 31 located in the second edge display area 213 is connected to the fan-out lead 41 through the second connecting line 33b, along the same direction, such as the direction from the third edge to the fourth edge, the distribution order of the column numbers of the signal lines 31 connected to each fan-out lead 41 is different from the distribution order of the column numbers of each signal line 31 in the display area 21.

[0056] For example, in the direction from the third edge to the fourth edge, the columns in which the signal lines 31 in the display area 21 are located are the 1st column, the 2nd column, the 10th column, the 7th column, the 8th column, the 9th column, the 10th column, and the 10th column. Assuming that the signal line in the 1st column is connected to the 5th fan-out lead via the first connecting line 33a, the signal line in the 10th column is connected to the 6th fan-out lead via the second connecting line 33b, and the signal lines in the other columns are directly connected to the fan-out lead 41 in the corresponding order, the column number distribution order of the signal lines 31 connected to these 10 fan-out leads 41 is 2-3-4-5-1-10-6-7-8-9. Therefore, it can be seen that, along the same direction, the column number distribution order of the signal lines 31 connected to each fan-out lead 41 is different from the column number distribution order of the signal lines 31 in the display area 21.

[0057] The column number of the signal line 31 actually refers to the arrangement number of the signal line 31 in the display area 21. The column number of the signal line 31 connected to each fan-out lead 41 actually refers to the arrangement number of the signal line 31 connected to the fan-out lead 41. For the sake of convenience of description, the arrangement number of the signal line 31 is used below to represent the column number of the signal line 31. For example, for the j-th column signal line 31, its corresponding arrangement number is j, where j is a positive integer.

[0058] In addition, in the direction from the third edge to the fourth edge of the display panel 20 (i.e., from left to right), the column numbers of the signal lines 31 are 1, 2, 3...K, respectively, where K represents the total number of columns (i.e., quantity) of the signal lines 31 in the display panel 20, which is a positive integer greater than 1; correspondingly, in the direction from the third edge to the fourth edge of the display panel 20, the column numbers of the fan-out leads 41 are also 1, 2, 3...K, respectively, and the number of fan-out leads 41 is equal to the number of signal lines 31.

[0059] exist Figure 1In the related art shown, if the display panel does not include first and second connecting lines, and each signal line is directly connected to a fan-out lead, the arrangement sequence of the signal line and the arrangement sequence of the fan-out lead to which it is connected are the same. Then, for the first display data input to the driver chip, the driver chip does not need to change the order of the first display data and directly transmits each first display data to the signal line via the fan-out lead. For example, the driver chip transmits the i-th first display data Di in the first display data sequence to the fan-out lead with arrangement sequence i, and then transmits it to the signal line with arrangement sequence i via the fan-out lead with arrangement sequence i.

[0060] Typically, the position number of the first display data within the first display data sequence input to the driver chip 42 is the same as the arrangement number of the signal line 31 to which it is to be transmitted. The position number refers to the position number of the first display data within the first display data sequence. For example, the i-th first display data Di within the first display data sequence has a corresponding position number of i, and the first display data Di with position number i is to be transmitted to the i-th column signal line 31.

[0061] However, when the signal lines 31 located in the first edge display area 212 are connected to the fan-out leads 41 via the first connection lines 33a, and the signal lines 31 located in the second edge display area 213 are connected to the fan-out leads 41 via the second connection lines 33b, there may be a situation where the arrangement number of the fan-out leads 41 differs from the arrangement number of the signal lines connected to the fan-out leads 41 in the direction from the third edge to the fourth edge of the display panel 20. For example, if the fan-out lead 41 with arrangement number i is connected to the signal line with arrangement number j, and i and j are different, if the driver chip 42 does not change the sequence of the input first display data, the i-th first display data Di in the first display data sequence will be transmitted to the fan-out lead 41 with arrangement number i, and then transmitted to the j-th column signal line 31 through the fan-out lead 41 with arrangement number i. However, in reality, the i-th first display data Di should be transmitted to the i-th column signal line 31, thus causing display abnormality.

[0062] Therefore, when the distribution order of the arrangement numbers of the signal lines 31 connected to each fan-out lead 41 along the same direction is different from the distribution order of the arrangement numbers of each signal line 31 in the display area 21, that is, the arrangement number of each fan-out lead 41 is different from the arrangement number of the signal line 31 connected to it, in order to ensure that the driver chip 42 can transmit display data to the correct signal line 31, it is necessary to separately manufacture driver chips according to the relationship between the arrangement number of the fan-out lead 41 and the arrangement number of the signal line 31 connected to it, so as to use different driver chips 42 to provide display data in the correct order to the signal line 31.

[0063] For different models of terminal devices, if the number and distribution positions of the signal lines 31 connected by the first connecting line 33a and the second connecting line 33b are different, different driver chips 42 are required to output display data, that is, different terminal devices need to be equipped with different driver chips 42, resulting in a higher design cost of the driver chip 42.

[0064] Based on this, an embodiment of the present application provides a display panel that, by providing a sequence change module within a driver chip 42, changes the order of display data input to the driver chip 42. For all display data of each row of sub-pixels, a first mapping relationship exists between the order of the display data after the sequence change and the order of the display data before the sequence change. Along the same direction, a second mapping relationship exists between the order of the arrangement numbers of the signal lines 31 within the display area 21 and the order of the arrangement numbers of the fan-out leads 41 to which they are connected. If the first mapping relationship is the same as the second mapping relationship, the sequence change module can be used to enable the driver chip 42 to input display data to the correct signal line 31. Therefore, when targeting different models of terminal devices, only the parameters input to the driver chip 42 need to be changed. Based on the sequence change algorithm designed within the driver chip 42, the driver chip 42 can input the second display data to the correct signal line 31. In other words, the driver chip in the embodiment of the present application is applicable to different types of terminal devices.

[0065] Hereinafter, the display data before the order change is referred to as the first display data, and the display data after the order change is referred to as the second display data. Since the driver chip transmits display data to each signal line 211 within the display area 21 simultaneously to all signal lines 211 of a column of sub-pixels, the display data before the order change for each row of sub-pixels can be referred to as the first display data sequence, and the display data after the order change for each row of sub-pixels can be referred to as the second display data sequence. Therefore, the number of first display data in the first display data sequence is equal to the number of signal lines 211, and the number of second display data in the second display data sequence is also equal to the number of signal lines 211. Compared to the first display data sequence, the second display data sequence differs only in the order of the individual display data.

[0066] In addition, there is a first mapping relationship between the sorting of the display data after the sequence change and the sorting of the display data before the sequence change, that is, there is a first mapping relationship between the arrangement number of the signal line corresponding to the second display data at the same position number and the arrangement number of the signal line corresponding to the first display data. For the convenience of subsequent description, the relationship between the arrangement number of the signal line corresponding to the first display data at the same position number and the arrangement number of the signal line corresponding to the second display data is referred to as a second corresponding relationship, and the second corresponding relationship is the opposite relationship of the first mapping relationship.

[0067] Correspondingly, there is a second mapping relationship between the arrangement number of the signal lines 31 in the display area 21 and the arrangement number of the fan-out leads 41 connected thereto, that is, there is a second mapping relationship between the arrangement number of each signal line 31 and the arrangement number of the fan-out lead 41 connected thereto. For the convenience of subsequent description, the relationship between the arrangement number of each fan-out lead 41 and the arrangement number of the signal line 31 connected thereto is referred to as a first corresponding relationship, and the first corresponding relationship and the second mapping relationship are opposite relationships to each other.

[0068] The following uses the first correspondence to describe the relationship between the arrangement number of each fan-out lead 41 and the arrangement number of the signal line 31 connected thereto, and uses the second correspondence to describe the relationship between the arrangement number of the signal line corresponding to the first display data and the arrangement number of the signal line corresponding to the second display data at the same position number.

[0069] Therefore, the arrangement sequence number of the signal line 31 corresponding to the i-th first display data Di in the first display data sequence is i. After the first display data Di is sequenced by the driver chip 42, the arrangement sequence number of the signal line 31 corresponding to the i-th second display data in the second display data sequence is j, that is, the i-th second display data is Dj, and the second corresponding relationship is ij. The i-th second display data Dj in the second display data sequence is output from the i-th pin of the driver chip 42 and then transmitted to the fan-out lead 41 with the arrangement sequence number i, that is, transmitted to the i-th fan-out lead 41. The fan-out lead with the arrangement sequence number i is connected to the signal line 31 with the arrangement sequence number j (directly or through the connecting line 33), that is, the first corresponding relationship is ij. The first corresponding relationship is the same as the second corresponding relationship, so that the i-th second display data Dj in the second display data sequence obtained after the sequence change can be correctly transmitted to the j-th column signal line 31.

[0070] Therefore, for different models of terminal devices, the same driver chip 42 can be used, and a sequence change module is set in the driver chip 42. When the first correspondence between the arrangement number of each fan-out lead 41 and the arrangement number of the signal line 31 connected to it is equivalent to the second correspondence between the arrangement number of the signal line 31 corresponding to the first display data at the same position number and the arrangement number of the signal line 31 corresponding to the second display data, the same driver chip 42 can be used to apply to different models of terminal devices, thereby improving the utilization rate of the driver chip 42 and reducing the design cost of the driver chip 42.

[0071] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above technical problems. The following specific embodiments can be implemented independently or in combination with each other. For the same or similar concepts or processes, some embodiments may not be described in detail.

[0072] For example, Figure 4 This is a schematic diagram of the structure of the driver chip in the embodiment of this application. Figure 4 As shown, for the driver chip 42 set in the binding area of ​​the display panel 20, the driver chip 42 includes a compensation module 421, a first cache module 422, a second cache module 423, a sequence change module 424, a third cache module 425, a fourth cache module 426, a level conversion module 427, a digital-to-analog conversion module 428 and an amplification module 429 connected in sequence.

[0073] During the actual driving process, when display data is input into the driver chip 42, the compensation module 421 within the driver chip 42 first performs different algorithmic compensation processing on each input display data (Data_in) at each display position. The display data input into the compensation module 421 of the driver chip 42 can be referred to as initial display data, and the display data after the compensation module 421 compensates the initial display data can be referred to as first display data.

[0074] Exemplarily, the compensation module 421 performs demura compensation or IR drop compensation on each input initial display data, which may be any one of the display data of the red sub-pixel, the display data of the green sub-pixel, and the display data of the blue sub-pixel.

[0075] Demura compensation is an external compensation method that mainly uses automated optical inspection (AOI) equipment to detect mura (brightness and darkness unevenness) on the display panel 20 and performs demura compensation after the mura is detected to reduce the mura phenomenon of the display panel 20.

[0076] Because each column of pixel driver circuits within the display panel 20 needs to be connected to an ELVDD signal line, and because the ELVDD signal line has a certain impedance, the power supply voltage signal transmitted on the ELVDD signal line inevitably has a certain voltage drop. This results in different voltage values ​​corresponding to the power supply voltage signal input from the same ELVDD signal line to each pixel driver circuit connected thereto. This, in turn, causes different drive currents input to the light-emitting devices from each pixel driver circuit connected to the same ELVDD signal line. These different drive currents can lead to uneven brightness on the display panel. Therefore, to improve the uneven brightness of the display panel caused by the impedance of the ELVDD signal line, different compensation voltage values ​​can be applied to the initial display data according to the position of each initial display data displayed.

[0077] After the compensation module 421 in the driver chip 42 performs algorithmic compensation on the input initial display data, the first display data obtained after the compensation is written into the first cache module 422. The first display data is then read from the first cache module 422 and written into the second cache module 423. The first display data is written into the first cache module 422, read from the first cache module 422, and written into the second cache module 423 in units of bits.

[0078] When all the first display data in the first display data sequence are written into the second buffer module 423 , all the first display data in the first display data sequence are read out from the second buffer module 423 and input into the sequence changing module 424 .

[0079] The first cache module 422 and the second cache module 423 in the driver chip 42 together constitute a first cache circuit, that is, the first cache circuit includes the first cache module 422 and the second cache module 423 connected in sequence.

[0080] like Figure 5 and Figure 6 As shown, for each row of sub-pixels, the first display data input to the sequence changing module 424 of the driver chip 42 is divided into a first data set Q1, a second data set Q2, a third data set Q3, and a fourth data set Q4. The signal lines 31 corresponding to the first display data in the first data set Q1 and the signal lines 31 corresponding to the first display data in the second data set Q2 are both located between the central axis and the third edge of the display panel 20, and the signal lines 31 corresponding to the first display data in the second data set Q2 are located between the signal lines 31 corresponding to the first display data in the first data set Q1 and the central axis of the display panel 20. The signal lines 31 corresponding to the first display data in the third data set Q3 and the signal lines 31 corresponding to the first display data in the fourth data set Q4 are both located between the central axis and the fourth edge of the display panel 20, and the signal lines 31 corresponding to the first display data in the third data set Q3 are located between the signal lines 31 corresponding to the first display data in the fourth data set Q4 and the central axis of the display panel 20.

[0081] Moreover, the signal lines 31 corresponding to the first display data in the first data set Q1 and the signal lines 31 corresponding to the first display data in the fourth data set Q4 are symmetrically distributed along the central axis of the display panel 20, that is, the number of first display data in the first data set Q1 is equal to the number of first display data in the fourth data set Q4; the signal lines 31 corresponding to the first display data in the second data set Q2 and the signal lines 31 corresponding to the first display data in the third data set Q3 are symmetrically distributed along the central axis of the display panel 20, that is, the number of first display data in the second data set Q2 is equal to the number of first display data in the third data set Q3, and the central axis extends along the first direction Y.

[0082] The first data set Q1 refers to a set of first display data that needs to be subsequently inserted into the second data set Q2, and the total number of first display data in the first data set Q1 is equal to the total number of columns of signal lines 31 in the first edge display area 212; the second data set Q2 and the third data set Q3 refer to sets of first display data that do not require data insertion, and the sum of the total number of first display data in the second data set Q2 and the total number of first display data in the third data set Q3 is equal to the total number of columns of signal lines 31 in the central display area 211; the fourth data set Q4 refers to a set of first display data that needs to be subsequently inserted into the third data set Q3, and the total number of first display data in the fourth data set Q4 is equal to the total number of columns of signal lines 31 in the second edge display area 213.

[0083] For example, Figure 5 and Figure 6 As shown, assuming that the total number of columns of signal lines in the display panel 20 is 5184, the number of first display data in the first display data sequence corresponding to each signal line 31 input into the driver chip 42 is 5184, namely, the first display data D1 of the 1st column signal line 31, the first display data D2 of the 2nd column signal line 31, to the first display data D5184 of the 5184th column signal line 31. Among them, the first data set Q1 refers to the set of the first display data D1 of the 1st column signal line 31 to the first display data D300 of the 300th column signal line 31, the second data set Q2 refers to the set of the first display data D301 of the 301st column signal line 31 to the first display data D2592 of the 2592nd column signal line 31, the third data set Q3 refers to the set of the first display data D2593 of the 2593rd column signal line 31 to the first display data D4884 of the 4884th column signal line 31, and the fourth data set Q4 refers to the set of the first display data D4885 of the 4885th column signal line 31 to the first display data D5184 of the 5184th column signal line 31.

[0084] Before using the sequence change module 424 to change the order of the input first display data, it is necessary to first determine the first display data at the starting insertion position and the first display data at the ending insertion position. In the following description, the starting insertion position is referred to as the starting insertion position sequence number, and the ending insertion position is referred to as the ending insertion position sequence number. The first display data at the starting insertion position sequence number can be located in the second data set Q2, and the first display data at the ending insertion position sequence number can be located in the third data set Q3. For example, in Figure 5 In the example, the starting insertion position number is 2218, that is, the first display data at the starting insertion position number is the display data D2218 of the 2218th column signal line, and the ending insertion position number is 2968, that is, the first display data at the ending insertion position number is the display data D2968 of the 2968th column signal line; Figure 6 The starting insertion position number is 2143, that is, the first display data at the starting insertion position number is the display data D2143 of the 2143th column signal line, and the ending insertion position number is 3043, that is, the first display data at the ending insertion position number is the display data D3043 of the 3043th column signal line.

[0085] After determining the first display data at the starting insertion position sequence number and the first display data at the ending insertion position sequence number, the first display data in the first data set Q1 is inserted starting from the first display data at the starting insertion position sequence number until all the first display data in the first data set Q1 are inserted before the critical position sequence number between the second data set Q2 and the third data set Q3; the first display data in the fourth data set Q4 is inserted starting from the critical position sequence number between the third data set Q3 and the second data set Q2 until all the first display data in the fourth data set Q4 are inserted before the ending insertion position sequence number. The critical position sequence number may also refer to the center position sequence number, i.e., 1 / 2 of the total number of columns K of the signal lines 31 of the display panel 20. For example, when the total number K of columns of the signal lines 31 in the display panel 20 is 5184, the center position sequence number is 2592.

[0086] Therefore, the embodiment of the present application inserts the first display data in the first data set Q1 and the fourth data set Q4 between the starting insertion position number and the ending insertion position number to sequentially change the first display data in the first display data sequence corresponding to each input signal line 31 to obtain a second display data sequence.

[0087] After the sequence changing module in the driver chip sequentially changes the first display data in the first display data sequence according to the above-mentioned insertion method to obtain the second display data sequence, the change patterns of the second display data in the second display data sequence are different. According to the different change patterns, the second display data in the second display data sequence can be divided into a first change data set, a second change data set, a third change data set, and a fourth change data set in ascending order of their position numbers, and the first change data set, the second change data set, the third change data set, and the fourth change data set all include multiple second display data.

[0088] The set of second display data with position numbers less than the starting insertion position number is referred to as the first change data set. Assuming the starting insertion position number is s, the position number i of each second display data item within the first change data set satisfies 0<i<s. In other words, in the embodiment of the present application, the position number of each second display data item within the first change data set is a positive integer greater than 1 and less than s, and the minimum position number of each second display data item within the first change data set is 1, and the maximum position number of each second display data item within the first change data set is s-1. The second display data item within the first change data set can be referred to as the first change data item.

[0089] For example, in Figure 5 In the first change data set, the second display data refers to the first second display data to the 2217th second display data in the second display data sequence; Figure 6 In the first change data set, the second display data refers to the first second display data to the 2142nd second display data in the second display data sequence.

[0090] The set of second display data whose position number is greater than or equal to the starting insertion position number and less than or equal to the center position number is called the second change data set. Assuming that the starting insertion position number is s and the center position number is K / 2, the position number i of each second display data in the second change data set satisfies s≤i≤K / 2. That is, the position number of each second display data in the second change data set in the embodiment of the present application is a positive integer greater than or equal to s and less than or equal to K / 2, and the minimum value of the position number of each second display data in the second change data set is equal to s, and the maximum value of the position number of each second display data in the second change data set is equal to K / 2.

[0091] For example, in Figure 5 In the second display data set, the second display data in the second change data set refers to the 2218th second display data to the 2592nd second display data in the second display data sequence; Figure 6 In the second display data set, the second display data in the second changed data set refers to the 2143rd second display data to the 2592nd second display data in the second display data sequence.

[0092] The set of second display data whose position number is greater than the center position number and less than the ending insertion position number is called the third change data set. Assuming that the center position number is K / 2 and the ending insertion position number is e, the position number i of each second display data in the third change data set satisfies K / 2<i<e. That is, the position number of each second display data in the third change data set in the embodiment of the present application is a positive integer greater than K / 2 and less than e, and the minimum value of the position number of each second display data in the third change data set is 1+K / 2, and the maximum value of the position number of each second display data in the third change data set is e-1.

[0093] For example, in Figure 5 In the third change data set, the second display data refers to the 2593rd second display data to the 2967th second display data in the second display data sequence; Figure 6 In the third change data set, the second display data refers to the 2593rd second display data to the 3042nd second display data in the second display data sequence.

[0094] The set of second display data having position numbers greater than or equal to the terminating insertion position number and less than or equal to the total number of columns of signal lines 31 in the display panel 20 is referred to as a fourth change data set. Assuming that the terminating insertion position number is e and the total number of columns of signal lines 31 in the display panel 20 is K, the position number i of each second display data in the fourth change data set satisfies e≤i≤K. In other words, the position number of each second display data in the fourth change data set in the embodiment of the present application is a positive integer greater than or equal to e and less than or equal to K, and the minimum value of the position number of each second display data in the fourth change data set is equal to e, and the maximum value of the position number of each second display data in the fourth change data set is equal to K. The second display data in the fourth change data set can be referred to as sixth change data.

[0095] For example, in Figure 5 In the fourth change data set, the second display data refers to the 2968th second display data to the 5184th second display data in the second display data sequence; Figure 6 In the fourth change data set, the second display data refers to the 3043rd second display data to the 5184th second display data in the second display data sequence.

[0096] In an embodiment of the present application, when inserting the first display data in the first data set Q1 into the second data set Q2, I first display data in the first data set Q1 can be inserted between every two adjacent first display data in the second data set Q2; when inserting the first display data in the fourth data set Q4 into the third data set Q3, I first display data in the fourth data set Q4 can be inserted between every two adjacent first display data in the third data set Q3.

[0097] like Figure 5 As shown, the first display data at the starting insertion position sequence number is the display data D2218 of the 2218th column signal line, and the first display data at the ending insertion position sequence number is the display data D2968 of the 2968th column signal line. Then, after 4 (i.e., I=4) first display data in the first data set Q1 are inserted between two adjacent first display data in the second data set Q2, in the second display data sequence, the first second display data is the second display data D301 of the 301st column signal line, the second second display data D302 is the second display data of the 302nd column signal line, and so on. The 2217th second display data D2517 is the second display data of the 2517th column signal line. That is, the first changed data set in the second display data sequence includes the second display data D301 of the 301st column signal line to the second display data of the 2517th column signal line.

[0098] In the second display data sequence, the 2218th second display data D2518 is the second display data of the 2518th column signal line, the 2219th second display data D300 is the second display data of the 300th column signal line, the 2220th second display data D299 is the second display data of the 299th column signal line, the 2221st second display data D298 is the second display data of the 298th column signal line, the 2222nd second display data D297 is the second display data of the 297th column signal line, the 2223rd second display data D2519 is the second display data of the 2519th column signal line, and so on. The 2592nd second display data D1 is the second display data of the 1st column signal line.

[0099] Correspondingly, in the second display data sequence, the 2593rd second display data D2593 is the second display data of the 2593rd column signal line, the 2594th second display data D5184 is the second display data of the 5184th column signal line, the 2595th second display data D5183 is the second display data of the 5183rd column signal line, the 2596th second display data D5182 is the second display data of the 5182nd column signal line, the 2597th second display data D5181 is the second display data of the 5181st column signal line, the 2598th second display data D2594 is the second display data of the 2594th column signal line, and so on. The 2967th second display data D4885 is the second display data of the 4885th column signal line.

[0100] In the second display data sequence, the 2968th second display data D2668 is the second display data of the 2668th column signal line, the 2969th second display data D2669 is the second display data of the 2669th column signal line, and so on. The 5184th second display data D4884 is the second display data of the 4884th column signal line.

[0101] Figure 5 The order of display data change shown is that four first display data in the first data set Q1 are inserted between every two adjacent first display data in the second data set Q2, and four second display data in the fourth data set Q4 are inserted between every two adjacent first display data in the third data set Q3, and the signal line 31 corresponding to the first display data at the starting insertion position number and the signal line 31 corresponding to the first display data at the ending insertion position number are symmetrically arranged along the central axis of the display panel 20.

[0102] For example, in Figure 5 In the second display data sequence shown, the 2218th second display data is the second display data D2518 on the 2518th column signal line, the 2223rd second display data is the second display data D2519 on the 2519th column signal line, and the second display data D300 on the 300th column signal line, the second display data D299 on the 299th column signal line, the second display data D298 on the 298th column signal line, and the second display data D297 on the 297th column signal line are inserted between the 2218th second display data and the 2223rd second display data; and, between the inserted second display data D297 on the 297th column signal line and the inserted second display data D296 on the 296th column signal line, there is only one first display data in the second data set Q2, which is the second display data D2519 on the 2519th column signal line.

[0103] It is understandable that the number of first display data in the first data set Q1 inserted between every two adjacent first display data in the second data set Q2 is not limited to 4, and can also be 3, 5, etc., and when inserting the first display data in the first data set Q1, as shown in FIG. Figure 5 As shown, the first display data in the first data set Q1 can be inserted every time one first display data in the second data set Q2 is inserted, or the first display data in the first data set Q1 can be inserted every time two, three, or other numbers of first display data in the second data set Q2 are inserted. Accordingly, the number of first display data in the fourth data set Q4 inserted between every two adjacent first display data in the third data set Q3 is not limited to four, and can also be three, five, or other numbers. When inserting the first display data in the fourth data set Q4, as shown in FIG. Figure 5 As shown, the first display data in the fourth data set Q4 can be inserted every time one first display data in the third data set Q3 is inserted, or the first display data in the fourth data set Q4 can be inserted every time two or three first display data in the third data set Q3 are inserted.

[0104] For example, Figure 6 As shown, in the second display data sequence, the first display data in the first data set Q1 is inserted every two first display data in the second data set Q2, and the first display data in the fourth data set Q4 is inserted every two first display data in the third data set Q3, i.e., N = 2. For example, in the second display data sequence, the 2148th second display data is the second display data D297 on the 297th column signal line, and the 2151st second display data is the second display data D296 on the 296th column signal line. Between the inserted second display data D297 on the 297th column signal line and the inserted second display data D296 on the 296th column signal line, there are two first display data originally in the second data set Q2: the second display data D2445 on the 2445th column signal line and the second display data D2446 on the 2446th column signal line.

[0105] It should be noted that the first display data and the second display data are only used to distinguish the display data before and after the sequence change. The first display data and the second display data corresponding to the same arrangement number are actually the same, but their position numbers within each data sequence are different. For example, the first display data D2446 of the 2446th column signal line is actually the same as the second display data D2446 of the 2446th column signal line, but the position number of the first display data D2446 of the 2446th column signal line in the first display data sequence is 2446. Figure 6As shown, the position number of the second display data D2446 of the 2446th column signal line in the second display data sequence is 2150.

[0106] In summary, for a certain display panel 20, the total number of columns of signal lines 31 in the display panel 20 is K columns, and the number of first display data in the first data set Q1 and the fourth data set Q4 is C, that is, the total number of columns of signal lines 31 in the first edge display area 212 and the second edge display area 213 is C columns. The number of first display data in the first data set Q1 inserted between every two adjacent first display data in the second data set Q2 is I, and the number of first display data in the fourth data set Q4 inserted between every two adjacent first display data in the third data set Q3 is also I. Moreover, in the second display data sequence obtained after inserting the first display data in the first data set Q1 and the first display data in the fourth data set Q4, the number of first display data in the second data set Q2 between two adjacent first display data in the first data set Q1 is N, and the number of first display data in the third data set Q3 between two adjacent first display data in the fourth data set Q4 is also N. Among them, K, C, I and N are all positive integers, the first display data corresponding to the starting insertion position number is Ds, the starting insertion position number s = K / 2-(I+N)×(C / I)+1, the first display data corresponding to the ending insertion position number is De, the ending insertion position number e = K / 2+(I+N)×(C / I)+1, s represents the starting insertion position number, and e represents the ending insertion position number.

[0107] according to Figure 5 and Figure 6 As shown in the second display data sequence, it can be seen that for the first change data set and the fourth change data set within the second display data sequence, since within the first display data sequence, the arrangement sequence numbers of the signal lines corresponding to the respective first display data are sequentially increased in ascending order of the position sequence numbers of the respective first display data, therefore, when the order of the respective first display data within the first display data sequence is changed by inserting the first display data within the first data set Q1 between the first display data within the second data set Q2, and by inserting the first display data within the fourth data set Q4 between the first display data within the third data set Q3, in the second display data sequence obtained, the arrangement sequence numbers of the signal lines corresponding to the respective first change data are also sequentially increased in ascending order of the position sequence numbers of the respective first change data, and the arrangement sequence numbers of the signal lines corresponding to the respective sixth change data are also sequentially increased in ascending order of the position sequence numbers of the respective sixth change data.

[0108] In some embodiments, if, when the order of the first display data in the first display data sequence is changed, only the first display data in the first data set Q1 is inserted between the first display data in the second data set Q2, and the first display data in the fourth data set Q4 is inserted between the first display data in the third data set Q3, and the order of the remaining first display data is not changed, then the absolute value of the difference between the arrangement sequence numbers of the signal lines corresponding to two adjacent first change data is 1, and the absolute value of the difference between the arrangement sequence numbers of the signal lines corresponding to two adjacent sixth change data is 1.

[0109] That is, in ascending order of the position numbers of the first change data, the arrangement numbers of the signal lines corresponding to the first change data are incremented by 1 at equal intervals. Since the difference between two adjacent position numbers is also 1, if the arrangement numbers of the signal lines corresponding to the first change data are incremented by 1 at equal intervals, then for any two first change data, the difference between the arrangement numbers of the signal lines corresponding to them is equal to the difference between their corresponding position numbers. Correspondingly, in ascending order of the position numbers of the sixth change data, the arrangement numbers of the signal lines corresponding to the sixth change data are incremented by 1 at equal intervals. Since the difference between two adjacent position numbers is also 1, if the arrangement numbers of the signal lines corresponding to the sixth change data are incremented by 1 at equal intervals, then for any two sixth change data, the difference between the arrangement numbers of the signal lines corresponding to them is equal to the difference between their corresponding position numbers.

[0110] For the second change data set in the second display data sequence, since the first display data in the first data set Q1 is inserted between the starting insertion position number and the center position number, the second change data set will include the first display data originally belonging to the first data set Q1 and the first display data originally belonging to the second data set Q2. Therefore, the second change data set can be divided into at least one first change data combination according to the insertion position of the first display data in the first data set Q1, and the second display data in each first change data combination is respectively the second change data and the third change data. Among them, the second change data refers to the first display data in the second data set Q2, that is, the second change data is the second display data of the signal line input to the central display area 211 (that is, the central display area with the central axis of the display panel 20 facing the first edge display area 212); the third change data refers to the first display data in the first data set Q1, that is, the third change data is the second display data of the signal line input to the first edge display area 212.

[0111] In some embodiments, after the first display data in the first data set Q1 is inserted between two adjacent first display data in the second data set Q2, the position sequence numbers corresponding to the first display data in the second data set Q2 adjacent to all the first display data in the first data set Q1 are the same. That is, in the second display data sequence, there is no first display data in the second data set Q2 between any two adjacent first display data in the first data set Q1. At this time, the second change data set can include a first change data combination.

[0112] In other embodiments, when inserting the first display data in the first data set Q1, the first display data in the first data set Q1 may be split into C / I parts, where C represents the total number of columns of the signal lines 31 in the first edge display area 212, I represents the number of first display data in the first data set Q1 that need to be inserted between two adjacent first display data in the second data set Q2, and C / I is a positive integer greater than 1. Each portion of the first display data in the first data set Q1 is inserted between two adjacent first display data with different position numbers in the second data set Q2. That is, in a second display data sequence obtained after inserting the first display data in the first data set Q1, first display data in the second data set Q2 may exist between some adjacent first display data in the first data set Q1. In this case, the second changed data set includes multiple first changed data combinations.

[0113] In summary, the second change data set may include at least one first change data combination, and the second display data within each first change data combination are respectively the second change data and the third change data. If the order of the first display data within the second data set Q2 is not changed when the first display data within the first data set Q1 is inserted, then the arrangement sequence numbers of the signal lines corresponding to the respective second change data increase in sequence according to the position sequence numbers of the respective second change data from small to large. Furthermore, since the third change data is actually the first display data within the first data set Q1, and the second change data is actually the first display data within the second data set Q2, within the same first change data combination, the arrangement sequence numbers of the signal lines corresponding to the third change data are smaller than the arrangement sequence numbers of the signal lines corresponding to the second change data. Therefore, according to the position sequence numbers of the respective second display data within the second change data set from small to large, the arrangement sequence numbers of the signal lines corresponding to the respective second display data within the second change data set may partially increase and partially decrease.

[0114] For the third change data set in the second display data sequence, since the first display data in the fourth data set Q4 is inserted between the center position sequence number and the end insertion position sequence number, the third change data set will include the first display data originally belonging to the fourth data set Q4 and the first display data originally belonging to the third data set Q3. Therefore, the third change data set can be divided into at least one second change data combination according to the insertion position of the first display data in the fourth data set Q4, and the second display data in each second change data combination is respectively the fourth change data and the fifth change data. Among them, the fourth change data refers to the first display data in the third data set Q3, that is, the fourth change data is the second display data of the signal line input to the central display area 211 (that is, the central display area with the central axis of the display panel 20 facing the second edge display area 213); the fifth change data refers to the first display data in the fourth data set Q4, that is, the fifth change data is the second display data of the signal line input to the second edge display area 213.

[0115] In some embodiments, after the first display data in the fourth data set Q4 is inserted between two adjacent first display data in the third data set Q3, the position sequence numbers corresponding to the first display data in the third data set Q3 adjacent to all the first display data in the fourth data set Q4 are the same. That is, in the second display data sequence, there is no first display data in the third data set Q3 between any two adjacent first display data in the fourth data set Q4. At this time, the third change data set can include a second change data combination.

[0116] In other embodiments, when inserting the first display data in the fourth data set Q4, the first display data in the fourth data set Q4 may be split into C / I parts, where C represents the total number of columns of the signal lines 31 in the second edge display area 213, I represents the number of first display data in the fourth data set Q4 that need to be inserted between two adjacent first display data in the third data set Q3, and C / I is a positive integer greater than 1. Each portion of the first display data in the fourth data set Q4 is inserted between two adjacent first display data with different position numbers in the third data set Q3. That is, in a second display data sequence obtained after inserting the first display data in the fourth data set Q4, first display data in the third data set Q3 may exist between some adjacent first display data in the fourth data set Q4. In this case, the third changed data set may include multiple second changed data combinations.

[0117] In summary, the third change data set may include at least one second change data combination, and the second display data within each second change data combination is respectively the fourth change data and the fifth change data. If the order of the first display data within the third data set Q3 is not changed when the first display data within the fourth data set Q4 is inserted, then the arrangement sequence numbers of the signal lines corresponding to the respective fourth change data are sequentially increased in ascending order of the position sequence numbers of the respective fourth change data. Furthermore, since the fifth change data is actually the first display data within the fourth data set Q4, and the fourth change data is actually the first display data within the third data set Q3, within the same second change data combination, the arrangement sequence number of the signal line corresponding to the fifth change data is greater than the arrangement sequence number of the signal line corresponding to the fourth change data. Therefore, in ascending order of the position sequence numbers of the respective second display data within the third change data set, the arrangement sequence numbers of the signal lines corresponding to the respective second display data within the third change data set may partially increase and partially decrease.

[0118] The above analysis shows that, according to the ascending order of the position numbers of the respective second display data within the second display data sequence, the arrangement numbers of the signal lines corresponding to the respective first change data within the first change data set increase successively, while the arrangement numbers of the signal lines corresponding to the respective second display data within the second change data set may partially increase and partially decrease. Therefore, the changing pattern of the arrangement numbers of the signal lines corresponding to the respective second display data within the first change data set is different from the changing pattern of the arrangement numbers of the signal lines corresponding to the respective second display data within the second change data set.

[0119] Correspondingly, according to the ascending order of the position numbers of the respective second display data in the second display data sequence, the arrangement numbers of the signal lines corresponding to the respective second display data in the fourth change data set also increase in sequence, while the arrangement numbers of the signal lines corresponding to the respective second display data in the third change data set may partially increase and partially decrease. Therefore, the changing pattern of the arrangement numbers of the signal lines corresponding to the respective second display data in the fourth change data set is different from the changing pattern of the arrangement numbers of the signal lines corresponding to the respective second display data in the third change data set.

[0120] It should be noted that, in some embodiments, when inserting the first display data in the first data set Q1 between the first display data in the second data set Q2, the order of the first display data in the second data set Q2 may be swapped so that the absolute value of the difference between the arrangement numbers of the signal lines corresponding to two adjacent first change data is not limited to 1. For example, the absolute value of the difference between the arrangement numbers of the signal lines corresponding to two adjacent first change data may be 2 or 3. Correspondingly, when inserting the first display data in the fourth data set Q4 between the first display data in the third data set Q3, the order of the first display data in the third data set Q3 may be swapped so that the absolute value of the difference between the arrangement numbers of the signal lines corresponding to two adjacent sixth change data is not limited to 1. For example, the absolute value of the difference between the arrangement numbers of the signal lines corresponding to two adjacent sixth change data may be 2 or 3.

[0121] The following is for Figure 5 and Figure 6 The sequence change rule shown schematically introduces a specific calculation method for the arrangement sequence numbers of the signal lines corresponding to each second display data in the second display data sequence at the same position number and each first display data in the first display data sequence.

[0122] For the i-th first display data in the first display data sequence, if its position number is less than the starting insertion position number, that is, in the first display data sequence, the i-th first display data is located before the first display data Ds corresponding to the starting insertion position number, that is, 0<i<s. For example, s can be 2218 or 2143, the i-th display data Di in the first display data sequence is sequenced. Assuming that the i-th second display data in the second display data sequence obtained after the sequence change is Dj, that is, at position number i, the sequence change module in the driver chip changes the first display data Di of the i-th column signal line to the second display data Dj of the j-th column signal line. In this case, j=i+C.

[0123] For the i-th first display data in the first display data sequence, if its position number is greater than or equal to the starting insertion position number and less than or equal to the center position number, that is, in the first display data sequence, the i-th first display data is located between the first display data Ds corresponding to the starting insertion position number and the first display data of the signal line at the center axis of the display panel 20, that is, s≤i≤K / 2, the position numbers between the starting insertion position number and the center position number are divided into C / I position number groups. The position numbers can also be called sequence numbers, and the position number groups can also be called sequence groups, such as the first position number group L1, the second position number group L2 to the 75th position number group L75. The combination of the second display data in each position number group before the center position number is called a first changed data combination.

[0124] After sequentially changing the i-th first display data Di in the first display data sequence, the first change data combination corresponding to each position number group includes I third change data and N second change data. For the second change data Dj in the m-th first change data combination in the second change data set, j=i+CI(m-1) can be obtained. For the r-th third change data Dj in the m-th first change data combination in the second change data set, j=CI(m-1)-(r-1) can be obtained, 1≤r≤I, 1≤m≤C / I.

[0125] For example, for Figure 5 The second change data D2518 in the first change data combination corresponding to the first position sequence number group L1 in the , at this time i = 2218, C = 300, I = 4, m = 1, then j = 2218 + 300 - 4 (1 - 1) = 2518; for Figure 5 The first (ie, r=1) third change data D300 in the first change data combination corresponding to the first position sequence number group L1, then j=300-4(1-1)-(1-1)=300.

[0126] For the i-th first display data in the first display data sequence, if its position number is greater than the center position number and less than the terminating insertion position number, that is, in the first display data sequence, the i-th first display data is located between the first display data of the signal line at the center axis of the display panel 20 and the first display data De corresponding to the terminating insertion position number, that is, K / 2<i<e. For example, e can be 2968 or 3043. The position numbers between the center position number and the terminating insertion position number are divided into C / I position number groups, such as the first position number group R1 to the 75th position number group R75. The combination of the second display data in each position number group after the center position number is called the second changed data combination.

[0127] After sequentially changing the i-th first display data Di in the first display data sequence, the second change data combination corresponding to each position number group includes I fifth change data and N fourth change data. For the fourth change data Dj in the m-th second change data combination in the third change data set, j=i+CI(C / I+m-1) can be obtained; for the r-th fifth change data Dj in the m-th second change data combination in the third change data set, j=KI(m-1)-(r-1), 1≤r≤I, 1≤m≤C / I.

[0128] For example, for Figure 5 The fourth change data D2593 in the first position sequence group R1, at this time i = 2593, C = 300, I = 4, m = 1, then j = 2593 + 300 - 4 (300 / 4 + 1 - 1) = 2593; for Figure 5 The first (i.e. r=1) fifth change data D4888 in the 75th position number group R75, then j=5184-4(75-1)-(1-1)=4888.

[0129] For the i-th first display data in the first display data sequence, if its position number is greater than or equal to the terminating insertion position number, that is, in the first display data sequence, the i-th first display data is located after the first display data De corresponding to the terminating insertion position number, that is, e≤i≤K, the i-th first display data Di in the first display data sequence is reordered. Assuming that the i-th second display data in the second display data sequence obtained after the reordering is Dj, then j=iC.

[0130] After insertion according to the above method, when the starting insertion position number and the ending insertion position number are symmetrically arranged along the center position number, the number of first change data in the first change data set can be equal to the number of sixth change data in the fourth change data set, which are both s-1.

[0131] When the number of first display data in the first data set Q1 and the number of first display data in the fourth data set Q4 are both C, and the number I of first data sets Q1 inserted between every two adjacent first display data in the second data set Q2 is equal to the number I of fourth data sets Q4 inserted between every two adjacent first display data in the third data set Q3, the number of first change data combinations included in the second change data set is equal to the number of second change data combinations included in the third change data set, which are both C / I.

[0132] Furthermore, the number of second change data included in each first change data combination is equal, which is N, and the number of third change data included in each first change data combination is equal, which is 1. The number of fourth change data included in each second change data combination is equal, which is N, and the number of fifth change data included in each second change data combination is equal, which is 1. In other words, the number of second change data included in the first change data combination is equal to the number of fourth change data included in the second change data combination, and the number of third change data included in the first change data combination is equal to the number of fifth change data included in the second change data combination.

[0133] like Figure 5 and Figure 6 As shown, within the same first change data combination, the difference between the arrangement sequence number of the signal line corresponding to the second change data and the arrangement sequence number of the signal line corresponding to the third change data is greater than 1; within the same second change data combination, the difference between the arrangement sequence number of the signal line corresponding to the fifth change data and the arrangement sequence number of the signal line corresponding to the fourth change data is greater than 1. For example, Figure 5 In the first first change data combination shown, the arrangement sequence number of the signal line corresponding to the second change data is 2518, and the arrangement sequence numbers of the signal lines corresponding to the third change data are 300, 299, 298 and 297 respectively. Then, the difference between the arrangement sequence number of the signal line corresponding to the second change data and the arrangement sequence number of the signal line corresponding to the third change data in the first first change data combination is greater than 1.

[0134] When the second change data set includes multiple first change data combinations, for example, Figure 5 and Figure 6 The second change data set shown includes 75 first change data combinations. The difference between the arrangement number of the signal line corresponding to the second change data with the smallest position number in the m+1th first change data combination and the arrangement number of the signal line corresponding to the second change data with the largest position number in the mth first change data combination is 1, that is, for two adjacent first change data combinations in the second change data set, the arrangement numbers of the signal lines corresponding to the second change data contained therein are from small to large.

[0135] Accordingly, when the third change data set includes multiple second change data combinations, for example, Figure 5 and Figure 6The third change data set shown includes 75 second change data combinations. The difference between the arrangement number of the signal line corresponding to the fourth change data with the smallest position number in the m+1th second change data combination and the arrangement number of the signal line corresponding to the fourth change data with the largest position number in the mth second change data combination is 1, that is, for two adjacent second change data combinations in the third change data set, the arrangement numbers of the signal lines corresponding to the fourth change data contained therein are from small to large.

[0136] Wherein, m is a positive integer, the position number of each second change data in the m+1th first change data combination is greater than the position number of the second change data in the mth first change data combination, and the position number of each fourth change data in the m+1th second change data combination is greater than the position number of the fourth change data in the mth second change data combination.

[0137] For example, if m is 1, Figure 6 In the example, the arrangement number of the signal line corresponding to the second change data with the smallest position number in the second first change data combination is 2445, and the arrangement number of the signal line corresponding to the second change data with the largest position number in the first first change data combination is 2444. Then, the difference between the arrangement number 2445 of the signal line corresponding to the second change data with the smallest position number in the second first change data combination and the arrangement number 2444 of the signal line corresponding to the second change data with the largest position number in the first first change data combination is 1.

[0138] In some embodiments, each first change data combination includes multiple second change data, that is, N is a positive integer greater than 1, and within the same first change data combination, the difference between the arrangement sequence number of the signal line corresponding to the z+1th second change data and the arrangement sequence number of the signal line corresponding to the zth second change data is 1, that is, within each first change data combination, the arrangement sequence numbers of the signal lines corresponding to two adjacent second change data increase in sequence at equal intervals of 1; each second change data combination includes multiple fourth change data, that is, N is a positive integer greater than 1, and within the same second change data combination, the arrangement sequence number of the signal line corresponding to the z+1th second change data is 1. The difference between the arrangement sequence number of the signal line corresponding to the z+1th fourth change data and the arrangement sequence number of the signal line corresponding to the zth fourth change data is 1, that is, within each second change data combination, the arrangement sequence numbers of the signal lines corresponding to two adjacent fourth change data increase in sequence at equal intervals of 1; wherein z is a positive integer less than N, the difference between the position sequence number of the z+1th second change data and the position sequence number of the zth second change data is 1, and the difference between the position sequence number of the z+1th fourth change data and the position sequence number of the zth fourth change data is also 1.

[0139] For example, in Figure 6In each first change data combination, the difference between the arrangement number of the signal line corresponding to the second second change data and the arrangement number of the signal line corresponding to the first second change data is 1, and in each second change data combination, the difference between the arrangement number of the signal line corresponding to the second fourth change data and the arrangement number of the signal line corresponding to the first fourth change data is 1.

[0140] It should be noted that the position where the first display data D1 of the first column signal line is inserted is the middle position of all the first display data of this row, that is, after the first display data D1 of the first column signal line is inserted, it becomes the K / 2th pixel of all the pixels in this row. Of course, it is understandable that the position where the first display data D1 of the first column signal line is inserted can also be changed to other positions, such as after the first display data D1 is inserted, it becomes the K / 4th pixel of all the pixels in this row or the 1+K / 2th pixel of all the pixels in this row, etc., and this embodiment of the application does not limit this. For example, for Figure 5 As shown in the sequential change rule of the display data, the first display data D1 of the first column signal line is sequentially changed from the first first display data in the first display data sequence to the 2592nd second display data in the second display data sequence. Of course, it can also be changed from the first first display data in the first display data sequence to the 2593rd second display data in the second display data sequence, and so on.

[0141] Correspondingly, the first display data D of the last column signal line K The inserted position can be close to the middle position of the second display data sequence, such as the first display data D of the last column of signal lines. K The inserted position is the K / 2+N+1th one in the second display data sequence; the first display data D of the last column signal line K The position after insertion may also deviate from the middle position of the second display data sequence, for example, the position after insertion becomes the 3K / 4th position of the second display data sequence, etc. This embodiment of the present application does not impose any limitation on this.

[0142] And, as Figure 5 and Figure 6 As shown, when inserting the first display data in the first data set Q1, the insertion is carried out in descending order according to the arrangement sequence number of the signal line corresponding to the first display data. When inserting the first display data in the fourth data set Q4, the insertion is also carried out in descending order according to the arrangement sequence number of the signal line corresponding to the first display data. Of course, it can be understood that the distribution pattern of the arrangement sequence number of the signal line corresponding to the first display data in the first data set Q1 and the first display data in the fourth data set Q4 inserted in the second display data sequence in the embodiment of the present application is not limited to Figure 5 and Figure 6 As shown, it can also be other ways.

[0143] In order to more clearly illustrate the distribution pattern of the arrangement sequence numbers of the signal lines corresponding to the first display data in the first data set Q1 and the fourth data set Q4 inserted in the second display data sequence in the embodiment of the present application, it can be explained from the distribution pattern of the arrangement sequence numbers of the signal lines corresponding to the third change data in each first change data combination and the fifth change data in each second change data combination, as well as from the distribution pattern of the arrangement sequence numbers of the signal lines corresponding to the third change data in two adjacent first change data combinations and the fifth change data in two adjacent second change data combinations.

[0144] In some embodiments, as Figure 5 and Figure 8 As shown, each first change data combination includes multiple third change data. Within the same first change data combination, the difference between the signal line sequence number corresponding to the rth third change data and the signal line sequence number corresponding to the r+1th third change data is 1, that is, the signal line sequence numbers corresponding to the third change data in each first change data combination are arranged from large to small. Each second change data combination includes multiple fifth change data. Within the same second change data combination, the difference between the signal line sequence number corresponding to the rth fifth change data and the signal line sequence number corresponding to the r+1th fifth change data is 1, that is, the signal line sequence numbers corresponding to the fifth change data in each second change data combination are arranged from large to small. Where r is a positive integer less than 1, the difference between the position sequence number of the r+1th third change data and the position sequence number of the rth third change data is 1, and the difference between the position sequence number of the r+1th fifth change data and the position sequence number of the rth fifth change data is also 1.

[0145] A situation such as Figure 5As shown, the second change data set includes multiple first change data combinations, and the difference between the minimum value of the arrangement sequence number of the signal lines corresponding to the third change data in the m-th first change data combination and the maximum value of the arrangement sequence number of the signal lines corresponding to the third change data in the m+1-th first change data combination is 1, that is, the arrangement sequence numbers of the signal lines corresponding to the third change data included in two adjacent first change data combinations are from large to small. The third change data set includes multiple second change data combinations, and the difference between the minimum value of the arrangement sequence number of the signal lines corresponding to the fifth change data in the m-th second change data combination and the maximum value of the arrangement sequence number of the signal lines corresponding to the fifth change data in the m+1-th second change data combination is 1, that is, the arrangement sequence numbers of the signal lines corresponding to the fifth change data included in two adjacent second change data combinations are from large to small. Wherein, m is a positive integer less than C / I, the position number of each third change data in the (m+1)th first change data combination is greater than the position number of the third change data in the (m)th first change data combination, and the position number of each fifth change data in the (m+1)th second change data combination is greater than the position number of the fifth change data in the (m)th second change data combination.

[0146] At this time, the difference between the arrangement sequence number of the signal line corresponding to the I-th third change data in the m-th first change data combination and the arrangement sequence number of the signal line corresponding to the I-th third change data in the m+1-th first change data combination is 1; the difference between the arrangement sequence number of the signal line corresponding to the I-th fifth change data in the m-th second change data combination and the arrangement sequence number of the signal line corresponding to the I-th fifth change data in the m+1-th second change data combination is 1.

[0147] That is, when inserting the first display data within the first data set Q1, the first display data can be inserted from largest to smallest according to the arrangement sequence number of the signal line corresponding to the first display data, i.e., inserted in reverse order. In this case, the first display data with smaller arrangement sequence numbers corresponding to the signal line of the first display data within the first data set Q1 will be closer to the center position of all the second display data in the second display data sequence after insertion. When inserting the first display data within the fourth data set Q4, the first display data can be inserted from largest to smallest according to the arrangement sequence number of the signal line corresponding to the first display data, i.e., inserted in reverse order. In this case, the first display data with larger arrangement sequence numbers corresponding to the signal line of the first display data within the fourth data set Q4 will be closer to the center position of all the second display data in the second display data sequence after insertion.

[0148] Another case, such as Figure 8As shown, the second change data set includes multiple first change data combinations, and the difference between the minimum value of the arrangement sequence number of the signal lines corresponding to the third change data in the m+1th first change data combination and the maximum value of the arrangement sequence number of the signal lines corresponding to the third change data in the mth first change data combination is 1, that is, the arrangement sequence numbers of the signal lines corresponding to the third change data included in two adjacent first change data combinations are from small to large. The third change data set includes multiple second change data combinations, and the difference between the minimum value of the arrangement sequence number of the signal lines corresponding to the fifth change data in the m+1th second change data combination and the maximum value of the arrangement sequence number of the signal lines corresponding to the fifth change data in the mth second change data combination is 1, that is, the arrangement sequence numbers of the signal lines corresponding to the fifth change data included in two adjacent second change data combinations are from small to large.

[0149] At this time, the difference between the arrangement sequence number of the signal line corresponding to the I-th third change data in the m+1-th first change data combination and the arrangement sequence number of the signal line corresponding to the 1-th third change data in the m-th first change data combination is 1; the difference between the arrangement sequence number of the signal line corresponding to the I-th fifth change data in the m+1-th second change data combination and the arrangement sequence number of the signal line corresponding to the 1-th fifth change data in the m-th second change data combination is 1.

[0150] Of course, it is understandable that when inserting the first display data in the first data set Q1, the arrangement numbers of the signal lines corresponding to the first display data inserted in each first change data combination are from large to small, while the arrangement numbers of the signal lines corresponding to the first display data inserted in two adjacent first change data combinations can be from small to large; correspondingly, when inserting the first display data in the fourth data set Q4, the arrangement numbers of the signal lines corresponding to the first display data inserted in each second change data combination are from large to small, while the arrangement numbers of the signal lines corresponding to the first display data inserted in two adjacent second change data combinations can be from small to large.

[0151] For example, the first display data inserted into the first first changed data combination are the first display data D4 of the 4th column signal line, the first display data D3 of the 3rd column signal line, the first display data D2 of the 2nd column signal line, and the first display data D1 of the 1st column signal line, while the first display data inserted into the second first changed data combination are the first display data D8 of the 8th column signal line, the first display data D7 of the 7th column signal line, the first display data D6 of the 6th column signal line, and the first display data D5 of the 5th column signal line.

[0152] In other embodiments, Figure 7 and Figure 9As shown, each first change data combination includes multiple third change data. Within the same first change data combination, the difference between the arrangement sequence number of the signal line corresponding to the r+1th third change data and the arrangement sequence number of the signal line corresponding to the rth third change data is 1, that is, the arrangement sequence numbers of the signal lines corresponding to the third change data in each first change data combination are arranged in ascending order. Each second change data combination includes multiple fifth change data. Within the same second change data combination, the difference between the arrangement sequence number of the signal line corresponding to the r+1th fifth change data and the arrangement sequence number of the signal line corresponding to the rth fifth change data is 1, that is, the arrangement sequence numbers of the signal lines corresponding to the fifth change data in each second change data combination are arranged in ascending order.

[0153] A situation such as Figure 7 As shown, the second change data set includes multiple first change data combinations, and the difference between the minimum value of the arrangement sequence number of the signal lines corresponding to the third change data in the m-th first change data combination and the maximum value of the arrangement sequence number of the signal lines corresponding to the third change data in the m+1-th first change data combination is 1, that is, the arrangement sequence numbers of the signal lines corresponding to the third change data included in two adjacent first change data combinations are from large to small. The third change data set includes multiple second change data combinations, and the difference between the minimum value of the arrangement sequence number of the signal lines corresponding to the fifth change data in the m-th second change data combination and the maximum value of the arrangement sequence number of the signal lines corresponding to the fifth change data in the m+1-th second change data combination is 1, that is, the arrangement sequence numbers of the signal lines corresponding to the fifth change data included in two adjacent second change data combinations are from large to small.

[0154] At this time, the difference between the arrangement sequence number of the signal line corresponding to the 1st third change data in the mth first change data combination and the arrangement sequence number of the signal line corresponding to the 1st third change data in the m+1th first change data combination is 1; the difference between the arrangement sequence number of the signal line corresponding to the 1st fifth change data in the mth second change data combination and the arrangement sequence number of the signal line corresponding to the 1st fifth change data in the m+1th second change data combination is 1.

[0155] That is to say, when inserting the first display data in the first data set Q1, the arrangement sequence numbers of the signal lines corresponding to the inserted first display data in the first data set Q1 can also be increased in each first change data combination in the second change data set. However, the closer the two adjacent first change data combinations are to the first change data combination with the center position number, the smaller the arrangement sequence numbers of the signal lines corresponding to the inserted first display data. For example, the first display data inserted in the first first change data combination are the first display data D297 of the 297th column signal line, the first display data D298 of the 298th column signal line, the first display data D299 of the 299th column signal line, and the first display data D300 of the 300th column signal line, while the first display data inserted in the second first change data combination are the first display data D293 of the 293rd column signal line, the first display data D294 of the 294th column signal line, the first display data D295 of the 295th column signal line, and the first display data D296 of the 296th column signal line. When inserting the first display data in the fourth data set Q4, in each second change data combination in the third change data set, the arrangement sequence number of the signal line corresponding to the inserted first display data in the fourth data set Q4 can also be increased from small to large, but for two adjacent second change data combinations, the closer to the second change data combination at the center position number, the larger the arrangement sequence number of the signal line corresponding to the inserted first display data.

[0156] Another case, such as Figure 9 As shown, the second change data set includes multiple first change data combinations, and the difference between the minimum value of the arrangement number of the signal line corresponding to each third change data in the m+1th first change data combination and the maximum value of the arrangement number of the signal line corresponding to each third change data in the mth first change data combination is 1, that is, the arrangement numbers of the signal lines corresponding to the third change data included in two adjacent first change data combinations are from small to large; the third change data set includes multiple second change data combinations, and the difference between the minimum value of the arrangement number of the signal line corresponding to each fifth change data in the m+1th second change data combination and the maximum value of the arrangement number of the signal line corresponding to each fifth change data in the mth second change data combination is 1, that is, the arrangement numbers of the signal lines corresponding to the fifth change data included in two adjacent second change data combinations are from small to large.

[0157] At this time, the difference between the arrangement sequence number of the signal line corresponding to the 1st third change data in the m+1th first change data combination and the arrangement sequence number of the signal line corresponding to the 1st third change data in the mth first change data combination is 1; the difference between the arrangement sequence number of the signal line corresponding to the 1st fifth change data in the m+1th second change data combination and the arrangement sequence number of the signal line corresponding to the 1st fifth change data in the mth second change data combination is 1.

[0158] That is to say, when inserting the first display data in the first data set Q1, the first display data can also be inserted in ascending order according to the arrangement sequence numbers of the signal lines corresponding to the first display data, that is, sequential insertion. At this time, the first display data with a larger arrangement sequence number of the signal line corresponding to the first display data in the first data set Q1 is closer to the center position of all the second display data in the second display data sequence after insertion; at this time, the first display data in the first data set Q1 inserted after the starting insertion position sequence number are the first display data D1 of the 1st column signal line, the first display data D2 of the 2nd column signal line, and up to the first display data D300 of the 300th column signal line. The first display data D300 of the 300th column signal line is the K / 2th first display data of all pixels in this row. When inserting the first display data in the fourth data set Q4, the first display data may be inserted in ascending order of the arrangement sequence numbers of the signal lines corresponding to the first display data, that is, sequentially inserted. In this case, the first display data with smaller arrangement sequence numbers of the signal lines corresponding to the first display data in the fourth data set Q4 is closer to the center position of all the second display data in the second display data sequence after insertion; for example, the first display data in the fourth data set Q4 inserted starting from the center position sequence number are, in sequence, the first display data D4885 of the 4885th column signal line, the first display data D4886 of the 4886th column signal line, and so on to the first display data D5184 of the 5184th column signal line.

[0159] Figures 7 to 9 The second display data sequence shown, with Figure 5 The difference of the second display data sequence shown is that the distribution pattern of the third change data in each first change data combination is different and the distribution pattern of the fifth change data in each second change data combination is different.

[0160] In addition, the start insertion position serial number and the end insertion position serial number may be symmetrically arranged along the center position serial numbers of all display data of a row of sub-pixels, or may be asymmetrically arranged.

[0161] Symmetrical setting means that the total amount of display data set from the starting insertion position number to the center position number is equal to the total amount of display data set from the position number after the center position number to the position number before the ending insertion position number; asymmetric setting means that the total amount of display data set from the starting insertion position number to the center position number is greater or less than the total amount of display data set from the position number after the center position number to the position number before the ending insertion position number.

[0162] When inserting the first display data in the first data set Q1 and the first display data in the fourth data set Q4, the insertion can be uniform or non-uniform. Uniform insertion means that the number I of first display data in the first data set Q1 inserted between two adjacent first display data in the second data set Q2 is equal, and the number I of first display data in the fourth data set Q4 inserted between two adjacent first display data in the third data set Q3 is equal. Non-uniform insertion means that the number I of first display data in the first data set Q1 inserted between two adjacent first display data in the second data set Q2 may be unequal, and / or the number I of first display data in the fourth data set Q4 inserted between two adjacent first display data in the third data set Q3 may be unequal. For example, four first display data in the first data set Q1 may be inserted between two first display data in the second data set Q2, and three first display data in the first data set Q1 may be inserted between another two first display data in the second data set Q2.

[0163] When inserting the first display data in the first data set Q1 and the first display data in the fourth data set Q4, the first display data originally belonging to the second data set Q2 and the third data set Q3 between the starting insertion position sequence number and the ending insertion position sequence number can be evenly distributed or unevenly distributed. Evenly distributed means that in the second display data sequence, the number N of second change data in each first change data combination is equal, and the number N of fourth change data in each second change data combination is equal; unevenly distributed means that in the second display data sequence, there are two first change data combinations with unequal numbers of second change data, and / or there are two second change data combinations with unequal numbers of fourth change data, for example, the number N of second change data in one first change data combination is 1, and the number N of second change data in another first change data combination is 2.

[0164] After the first display data in the first display data sequence is reordered using the sequence changing module 424, each second display data in the reordered second display data sequence is sequentially written into the third buffer module 425. The second display data is then read out of the third buffer module 425 and written into the fourth buffer module 426. Subsequently, the second display data is read out of the fourth buffer module 426 and input into the level conversion module 427.

[0165] The third cache module 425 and the fourth cache module 426 in the driver chip 42 together constitute a second cache circuit, that is, the second cache circuit includes the third cache module 425 and the fourth cache module 426 connected in sequence.

[0166] It should be noted that the number of cache modules between the order changing module 424 and the level conversion module 427 is not limited to two, that is, the number of cache modules included in the second cache circuit is not limited to two. When the write speed of the second display data to the cache module and the read speed of the second display data from the cache module are fast enough, a cache module can also be set between the order changing module 424 and the level conversion module 427. The embodiment of the present application does not limit the number of cache modules between the order changing module 424 and the level conversion module 427.

[0167] In addition, when writing the second display data obtained after the sorting process into the third cache module 425, the sequence changing module 424 writes each second display data obtained after processing into the third cache module 425; after the third cache module 425 caches all the second display data after processing in this row, all the second display data after processing in this row are written into the fourth cache module 426, and when reading the second display data from the fourth cache module 426, all the second display data in this row (that is, all the second display data in the second display data sequence) are also read out.

[0168] Since the level conversion module 427 also needs to be connected to the digital-to-analog conversion module 428, and the digital-to-analog conversion module 428 itself has a reference voltage, the digital-to-analog conversion module 428 can only recognize the second display data when the voltage of the second display data matches the reference voltage of the digital-to-analog conversion module 428. Therefore, the level conversion module 427 performs level conversion on the input second display data and inputs the converted second display data to the digital-to-analog conversion module 428.

[0169] For example, assuming that the second display data read from the fourth cache module 426 is data 1, its corresponding actual data voltage is 1.2V, but the reference voltage of the digital-to-analog conversion module 428 is 3.3V. Therefore, the level conversion module 427 needs to convert the input second data voltage 1.2V to 3.3V to ensure that the digital-to-analog conversion module 428 can correctly identify data 1.

[0170] Since the first display data input into the driver chip 42 is a digital signal, the second display data output from the level conversion module 427 is also a digital signal. Therefore, it is necessary to input the second display data output from the level conversion module 427 into the digital-to-analog conversion module 428, and perform digital-to-analog conversion on the input second display data after level conversion through the digital-to-analog conversion module 428, so as to convert the second display data of the digital signal into the second display data of the analog signal.

[0171] After the digital-to-analog conversion module 428 performs digital-to-analog conversion on the second display data, the second display data in the form of an analog signal is input to the amplification module 429. The amplification module 429 amplifies the input second display data after analog-to-digital conversion, and the amplified second display data (Data_out) is output from the pin of the driver chip 42.

[0172] The second display data outputted by the pin of the driver chip 42 is inputted to the binding terminal through the connection traces on the COF 43 and then transmitted to each fan-out lead 41 through the binding terminal. Each fan-out lead 41 transmits the display data to the signal line 31 connected thereto.

[0173] In some embodiments, all display data of sub-pixels in the same row are output from small to large according to the pin definition data of the driver chip 42, that is, the i-th display data in each row of sub-pixels is output from pin i of the driver chip 42, and pin i of the driver chip 42 is connected to the i-th fan-out lead.

[0174] Among all the display data of sub-pixels in each row, the i-th first display data in the first display data sequence is the display data Di of the i-th column signal line. The i-th second display data in the second display data sequence obtained after the order is changed is the display data Dj of the j-th column signal line. The i-th second display data Dj in the second display data sequence will be output from the i-th pin of the driver chip 42 and then output to the i-th fan-out lead 41. The i-th fan-out lead 41 is connected to the j-th column signal line 31 (directly or through the connecting line 33), so that the i-th second display data Dj in the second display data sequence can be correctly transmitted to the j-th column signal line 31.

[0175] After the sort order of all the first display data for each row of sub-pixels is changed, each piece of second display data obtained after the change is output from the corresponding pin of the driver chip 42 to the fan-out lead 41 according to the sort order. For example, the first piece of second display data is output from pin 1 of the driver chip 42 to the first fan-out lead 41, the second piece of second display data is output from pin 2 of the driver chip 42 to the second fan-out lead 41, and so on. The 5184th piece of second display data is output from pin 5184 of the driver chip 42 to the 5184th fan-out lead 41.

[0176] In adopting Figure 2 and Figure 3 In the display panel 20 shown, since the first corresponding relationship between the arrangement number of each fan-out lead 41 and the arrangement number of the signal line 31 connected thereto is equivalent to the second corresponding relationship between the arrangement number of the signal line 31 corresponding to the first display data at the same position number and the arrangement number of the signal line 31 corresponding to the second display data, the second display data obtained after the change can be transmitted to the correct signal line 31 through the fan-out lead 41.

[0177] For example, the first fan-out lead 41 is connected to the 301st column signal line 31, the second fan-out lead 41 is connected to the 302nd column signal line 31, the 2592nd fan-out lead 41 is connected to the 1st column signal line 31, and the 5184th fan-out lead 41 is connected to the 4884th column signal line. In this way, the first second display data D301 is output to the 301st column signal line 31 through the first fan-out lead 41, the second second display data D302 is output to the 302nd column signal line 31 through the second fan-out lead 41, the 2592nd second display data D1 is output to the 1st column signal line 31 through the 2592nd fan-out lead 41, and the 5184th second display data D4884 is output to the 4884th column signal line 31 through the 5184th fan-out lead 41.
