In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
Fig. 2 is a schematic structural diagram of a display panel according to an embodiment of the invention. As shown in fig. 2, the display panel includes a display area B and a non-display area C.
The display region B is provided with a plurality of data lines 21 and a plurality of sub-pixels 22 arranged in an array, wherein one data line 21 is electrically connected with one column of sub-pixels 22.
The display region B includes a first display region B1 and a second display region B2 in a first direction, which is a row direction (i.e., a horizontal direction shown in fig. 2) of the plurality of sub-pixels 22. The first display region B1 includes a first edge in a second direction, which is a column direction (i.e., a vertical direction shown in fig. 2) of the plurality of sub-pixels 22, the first edge being recessed toward the inside of the first display region B1, the recessed portion forming a notch, and the irregular region a being formed on a side of the notch away from the first display region B1. Due to the presence of the irregular area a, the number of sub-pixels 22 in any column of sub-pixels 22 in the first display area B1 is less than the number of sub-pixels 22 in any column of sub-pixels 22 in the second display area B.
An integrated circuit 23 and a lead 24 corresponding to the data line 21 are provided in the non-display area C on the side of the display area B away from the notch. Each data line 21 in the display area B is electrically connected to the integrated circuit 23 in the integrated circuit bonding area D through its corresponding lead line 24.
The plurality of data lines 21 in the display region B include a plurality of first data lines 211 disposed in the first display region B1, and a plurality of second data lines 212 disposed in the second display region B2. Wherein the sum of the lengths of each first data line 211 and its corresponding lead line 24 in the at least one first data line 211 is greater than or equal to the sum of the lengths of each second data line 212 and its corresponding lead line 24 in the at least one second data line 212.
In the display panel provided by the embodiment of the invention, when the display region B includes the first display region B1 and the second display region B2, and the number of sub-pixels 22 in one column in the second display region B2 is less than the number of sub-pixels 22 in one column in the second display region B2, the data lines in the first display region B1 and/or the lead lines corresponding to the data lines in the first display region B1 are subjected to the length extension processing, so that the sum of the lengths of each first data line 211 in at least one first data line 211 in the first display region B1 and the lead line 24 corresponding thereto is greater than or equal to the sum of the lengths of each second data line 212 in at least one second data line 212 in the second display region B2 and the lead line 24 corresponding thereto, thereby increasing the load of each extended data line, that is, in other words, of the data lines 211 in the at least one first data line 211, and the load difference of each data line in the at least one first data line 211 and the data line in the second display region B2 can be reduced, the current of each data line in the at least one first data line 211 is similar to or even equal to the current of each data line in the second display area B2, thereby improving the problem of uneven display brightness of the display panel.
Optionally, in the display panel provided in the embodiment of the present invention, a length of each data line and/or lead line corresponding to each column of sub-pixels in the first display area B1 may be extended, so that a sum of a length of any one first data line 211 and a corresponding lead line 24 in the first display area B1 is greater than or equal to a length of any one second data line 212 and a corresponding lead line 24 in the second display area B2. Thus, the current of each data line in the first display area B1 can be made to be similar to or even equal to the current of the data line in the second display area B2, and the problem of uneven display brightness of the display panel caused by different loads of the data lines in the first display area B1 and the data lines in the second display area B2 is further improved.
In the following embodiments, the technical solution of the present invention is mainly described in detail by taking the length extension process of the data line and/or the lead line corresponding to each column of sub-pixels in the first display area B1 as an example.
Optionally, in order to improve flexibility of the solution, in the display panel provided in the embodiment of the present invention, when the sum of the lengths of each first data line 211 in the at least one first data line 211 in the first display region B1 and the corresponding lead wire 24 is greater than or equal to the sum of the lengths of each second data line 212 in the at least one second data line 212 in the second display region B2 and the corresponding lead wire 24, the length extension processing may be performed on only the data line in the first display region B1, may be performed on only the lead wire corresponding to the data line in the first display region B1, may be performed on both the data line in the first display region B1 and the lead wire corresponding to the data line in the first display region B1, which is not limited in this implementation of the present invention.
Next, a scheme of performing the length extension processing on the data lines in the first display region B1 will be described.
Optionally, fig. 3 is another schematic structural diagram of the display panel in the embodiment of the present invention. As shown in fig. 3, in the display panel provided by the embodiment of the invention, the length of each first data line 211 in the at least one first data line 211 is greater than or equal to the length of each second data line 212 in the at least one second data line 212. That is, by performing the length extension processing on the data lines in the first display area B1, the load of the data lines in the first display area B1 is increased, and the difference between the load of the data lines in the second display area B2 is reduced, so that the current of the data lines in the first display area B1 is close to or equal to the current of each data line in the second display area B2, and thus the problem of uneven display brightness of the display panel can be improved. In addition, since the length of the data line 21 is extended, the width of the bonding region D of the integrated circuit in the second direction does not need to be increased, which is more beneficial to the narrow frame design of the display panel.
Optionally, in the display panel provided in the implementation of the present invention, as shown in fig. 3, each of the at least one first data line 211 includes a portion extending along a first direction and a portion extending along a second direction, where the second direction is a column direction of the plurality of sub-pixels 22. In this way, by winding and routing the data lines in the first display area B1, the load of the data lines in the first display area B1 can be increased, the difference between the load of the data lines in the second display area B2 can be reduced, and the problem of uneven display brightness of the display panel can be solved.
Optionally, in the display panel provided in the embodiment of the present invention, since the increased data line portion occupies a part of the display panel space, in order to reduce or even avoid the influence of the increased data line portion on the aperture ratio of the sub-pixels as much as possible, as shown in fig. 3, each first data line 211 in the at least one first data line 211 is routed along the spacing region between adjacent sub-pixels 22. By the method, the problem of uneven display brightness of the display panel can be improved, meanwhile, the influence on the aperture opening ratio of the sub-pixels is reduced, and the display effect of the display panel is better guaranteed.
Optionally, in order to improve flexibility of the solution, in the display panel provided in the embodiment of the present invention, a portion of each first data line 211 in the at least one first data line 211, which extends along the first direction, may pass through one column of sub-pixels 22, or may pass through multiple columns of sub-pixels 22, which is not limited in this embodiment of the present invention.
For example, as shown in fig. 3, the portions of the data lines a, b, and c extending in the first direction pass through a column of sub-pixels 22.
For example, fig. 4 is a schematic structural diagram of another display panel in the embodiment of the present invention. As shown in fig. 4, a portion of the data line a extending in the first direction passes through two columns of sub-pixels 22. It should be noted that, in fig. 4, for convenience of illustrating the routing manner of the data line a, the data lines of the sub-pixels in other columns in the first display area B1 are not illustrated, and the routing manner of the data lines of the sub-pixels in other columns may refer to the routing manner of the data line a, which is not necessarily illustrated in the embodiment of the present invention.
Of course, in a specific implementation, the first data line 211 may extend in the first direction in other implementations besides the above two implementations, for example, a portion of the data line a extending in the first direction passes through three columns of sub-pixels 22, four columns of sub-pixels 22, and the like.
This embodiment provides multiple routing ways for the first data line 211, which improves the flexibility of the scheme.
Optionally, in the display panel provided in the implementation of the present invention, a portion of each of the at least one first data line 211 extending along the first direction and a portion of each of the at least one first data line 211 extending along the second direction are alternately arranged in the second direction, so that each of the at least one first data line 211 is in a "bow" shaped routing structure, such as data lines a, b, and c shown in fig. 3 and data line a shown in fig. 4, which are all in a "bow" shaped routing structure.
By the embodiment, the first data line 211 can be extended in winding, and the problem of uneven display brightness of the display panel is solved.
Optionally, in the display panel provided in the embodiment of the present invention, the display panel includes at least two metal layers, and the at least two metal layers are insulated from each other.
Each of the at least one first data line 211 includes a first trace portion and a second trace portion all located in the same metal layer, such as in the second metal layer M2.
In the process of manufacturing the display panel, the bending and routing of the first data line 211 in the M2 layer can be realized by changing the Mask pattern design of the M2 process.
Through the embodiment, the process complexity of manufacturing the display panel can be reduced, and the manufacturing cost is reduced.
Optionally, in order to avoid the increased data line portion from occupying the aperture ratio of the sub-pixels as much as possible, each first data line 211 in the at least one first data line 211 includes a first trace portion and a second trace portion, where the first trace portion and the second trace portion are located in different metal layers, for example, the first trace portion is routed in the M2 layer, and the second trace portion is routed in the third metal layer M3 (a newly added metal layer).
In the process of manufacturing the display panel, on the basis of manufacturing the M2 layer, a process is added to extend the data lines to the M3 layer and perform corresponding Mask pattern design, so that the data lines can be bent and wound in different metal layers, wherein the metal line parts of different layers can be communicated through punching.
Through the implementation mode, the first data line 211 is wound in different layers, so that the opening area of the sub-pixel occupied by the data line part of the first data line 211 can be effectively reduced or even avoided, and the display effect of the display panel is better ensured.
Next, a description will be given of a scheme of performing the length extension processing on the lead lines corresponding to the data lines in the first display region B1.
Optionally, fig. 5 is another schematic structural diagram of the display panel in the embodiment of the present invention. As shown in fig. 5, in the display panel provided by the embodiment of the present invention, each lead line 24 of the at least one lead line 24 electrically connected to the first data line 211 in the first display region B1 has a length greater than that of each lead line 24 of the at least one lead line 24 electrically connected to the second data line 212 in the second display region B2. That is, the length of the lead line corresponding to the data line in the first display area B1 is extended, so as to increase the load of the data line in the first display area B1 and reduce the difference between the load of the data line in the second display area B2, so that the current of the extended data line in the first display area B1 is similar to or even equal to the current of the data line in the second display area B2, thereby improving the problem of uneven display brightness of the display panel. Meanwhile, the length of the data line in the display panel is not required to be changed, so that the opening area of the sub-pixel in the display panel is not influenced.
Optionally, in the display panel provided in the embodiment of the present invention, the length of the lead line corresponding to each data line 211 in the first display region B1 may be extended, so that the length of any lead line 24 electrically connected to the first data line 211 in the first display region B1 is greater than the length of any lead line 24 electrically connected to the second data line 212 in the second display region B2. In this way, the load of each data line in the first display area B1 and the load of each data line in the second display area B are similar or even equal, and the problem of display brightness unevenness of the display panel due to the load of the data lines in the first display area B1 and the load of the data lines in the second display area B2 are different is further improved.
Optionally, in the display panel provided in the embodiment of the present invention, in order to facilitate the bonding of the extended lead 24 and the integrated circuit 23, the integrated circuit bonding region D may be extended along the extending direction of the lead 24, as shown in fig. 5, a shape of a portion of the integrated circuit bonding region D where the lead 24 electrically connected to the first data line 211 in the first display region B1 is located is a special shape (arc shape) matching with the shape of the notch.
The above description has been made of the scheme of performing the length extension process on the data lines in the first display region B1 and the scheme of performing the length extension process on the lead lines corresponding to the data lines in the first display region B1, respectively, and as described above, in specific implementation, the two schemes may be implemented in combination with each other, for example, as shown in fig. 2, the length extension process is simultaneously performed on the data lines in the first display region B1 and the lead lines corresponding to the data lines in the first display region B1. When the data lines in the first display region B1 and the leads corresponding to the data lines in the first display region B1 are subjected to the length extension processing at the same time, a specific implementation manner of performing the length extension processing on the data lines in the first display region B1 may refer to the embodiments shown in fig. 3 to 6, and a specific implementation manner of performing the length extension processing on the leads corresponding to the data lines in the first display region B1 may refer to the embodiment shown in fig. 5, which is not described again in the embodiments of the present invention.
Optionally, in order to improve flexibility of the solution, the special-shaped area in the display panel provided in the embodiment of the present invention may be in other positions besides the central position of the upper edge of the display panel shown in fig. 2 to 5, and the embodiment of the present invention is not limited in particular.
For example, fig. 6 is another schematic structural diagram of the display panel in the embodiment of the present invention, and in the display panel shown in fig. 6, the special-shaped area is at the upper left corner position of the display panel.
For another example, fig. 7 is another schematic structural diagram of the display panel in the embodiment of the present invention, and in the display panel shown in fig. 7, the display area B surrounds the special-shaped area a.
Optionally, in order to improve flexibility of the scheme, the special-shaped area a in the display panel provided in the embodiment of the present invention may be in a semicircular shape shown in fig. 2 to 6, or may be in another shape, and the embodiment of the present invention is not particularly limited.
For example, the irregular area a in the display panel shown in fig. 7 is a rounded rectangle.
For another example, fig. 8 to 10 are schematic structural diagrams of another display panel in an embodiment of the present invention, where the irregular area a in the display panel shown in fig. 8 is a right-angled rectangle, the irregular area a in the display panel shown in fig. 9 is an ellipse, and the irregular area a in the display panel shown in fig. 10 is a triangle.
Optionally, in order to improve flexibility of the scheme, the display panel provided by the embodiment of the invention is also suitable for a product in which the display area B has a rounded design, that is, the irregular area a may not exist in the display panel.
