Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Embodiments of the present application provide a display panel, which will be described in detail below.
Referring to fig. 1-2, fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present disclosure. Fig. 2 is a partially enlarged view of a region a of a display panel provided in an embodiment of the present application. The display panel 100 includes a through hole 10, a non-display area 20, a display area 30, and a data line 40.
Wherein the non-display area 20 surrounds at least a portion of the through hole 10; the display area 30 surrounds at least a portion of the non-display area 20.
The data line 40 includes at least two first data lines 41, at least two second data lines 42, and at least two loop lines 43. The first data line 41 and the second data line 42 are located in the display area 30. The surrounding lines 43 are disposed in the non-display area 20 and around the through holes 10. The first data line 41 includes a first straight portion 411 and a second straight portion 422. The first linear portion 411 is connected to the second linear portion 412 via the surrounding line 43.
In the description of the present application, the terms "first", "second", "third", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, features defined as "first", "second", "third" may explicitly or implicitly include one or more of the described features.
In some embodiments, the adjacent surrounding lines 43 are arranged in different layers, so that the occupied area of the surrounding lines 43 is reduced, thereby reducing the size of the non-display area 20 and increasing the screen occupation ratio of the display panel 100.
In some embodiments, when the adjacent surrounding wires 43 are disposed in different layers, the adjacent surrounding wires 43 may be staggered, thereby reducing parasitic capacitance between the adjacent surrounding wires 43.
In some embodiments, the first straight portion 411 of at least two first data lines 41 is connected to the second straight portion 412 by one loop line 43. For example, as shown in fig. 3, the first straight portions 411 of the two first data lines 41 are connected to the second straight portion 412 through one loop line 43. For another example, the first straight portions 411 of the three first data lines 41 are connected to the second straight portion 412 through one surrounding line 43. Thereby reducing the number of the surrounding lines 43 within the non-display area 20, so that the size of the non-display area 20 is reduced, increasing the screen ratio of the display panel 100.
In order to reduce the difference in the number of data lines between the non-display area 20 and the display area 30, in the embodiment of the present application, the first straight portion 411 of at most 20 first data lines 41 is connected to the second straight portion 412 by one loop line 43.
In the embodiment of the present application, the surrounding line 43 is disposed in the same layer or different layers with respect to the first data line 41. When the surrounding line 43 is disposed in a different layer from the first data line 41, the first and second straight portions 411 and 412 of the first data line 41 are connected to the surrounding line 43 through a connection hole.
In the embodiment of the present application, the surrounding line 43 corresponding to the first data line 41 close to the center of the through hole 10 in the direction perpendicular to the first data line 41 is a first surrounding line, and the surrounding line 43 corresponding to the first data line 41 far from the center of the through hole 10 in the direction perpendicular to the first data line 41 is a second surrounding line.
In the embodiment of the present application, the sum of the resistance of the first loop winding and the resistance of the first data line 41 corresponding to the first loop winding is equal to the sum of the resistance of the second loop winding and the resistance of the first data line 41 corresponding to the second loop winding, so that the sum of the impedance of the first loop winding and the impedance of the first data line 41 corresponding to the first loop winding is equal to the sum of the impedance of the second loop winding and the impedance of the first data line 41 corresponding to the second loop winding.
Therefore, the problem that the display panel 100 has nonuniform display due to the fact that the length of the first data line 41 close to the center of the through hole 10 in the direction perpendicular to the first data line 41 is short, and the length of the first data line 41 away from the center of the through hole 10 in the direction perpendicular to the first data line 41 is long, so that the impedance of the first data line 41 close to the center of the through hole 10 in the direction perpendicular to the first data line 41 is smaller than the impedance of the first data line 41 away from the center of the through hole 10 in the direction perpendicular to the first data line 41, and the load of the first data line 41 close to the center of the through hole 10 in the direction perpendicular to the first data line 41 is smaller than the load of the first data line 41 away from the center of the through hole 10 in the direction perpendicular to the first data line 41 is solved.
Specifically, the length of the first data line 41 near the center of the via hole 10 in the direction perpendicular to the first data line 41 is shorter, and the length of the first data line 41 far from the center of the via hole 10 in the direction perpendicular to the first data line 41 is longer. Therefore, the resistance of the first data line 41 near the center of the via hole 10 in the direction perpendicular to the first data line 41 is smaller than the resistance of the first data line 41 far from the center of the via hole 10 in the direction perpendicular to the first data line 41.
In order to make the sum of the resistance of the first surrounding line and the resistance of the first data line 41 corresponding to the first surrounding line equal to the sum of the resistance of the second surrounding line and the resistance of the first data line 41 corresponding to the second surrounding line, the resistance of the first surrounding line is set to be greater than the resistance of the second surrounding line, so as to compensate the total load of the first surrounding line and the first data line 41 corresponding to the first surrounding line, and improve the display uniformity of the display panel 100.
In some embodiments, the first loop wire may be made of a high resistance material and the second loop wire may be made of a low resistance material, such that the resistance of the first loop wire is greater than the resistance of the second loop wire. That is, the resistivity of the material of the first loop wire is larger than the resistivity of the material of the second loop wire.
In the embodiment of the present application, when the first data line 41 and the surrounding line 43 corresponding to the first data line 41 are disposed in different layers, the first straight portion 411 and the second straight portion 412 of the first data line 41 are connected to the surrounding line 43 through a connection hole. Therefore, when the first data line 41 and the surrounding line 43 corresponding to the first data line 41 are arranged in different layers, the resistance of the connection hole can be adjusted by arranging the sectional area of the connection hole. Specifically, the sectional area of the connection hole corresponding to the first surrounding line may be set to be smaller than the sectional area of the connection hole corresponding to the second surrounding line, so as to increase the sum of the resistance of the first data line corresponding to the first surrounding line and the resistance of the first surrounding line, thereby compensating the total load of the first surrounding line and the first data line 41 corresponding to the first surrounding line, and improving the display uniformity of the display panel 100.
The closer the two surrounding wires 43 are, the larger the parasitic capacitance thereof will be. In some embodiments, the distance between the surrounding lines corresponding to two adjacent first data lines 41 close to the center of the through hole 10 in the direction perpendicular to the first data line 41 may be set smaller than the distance between the surrounding lines corresponding to two adjacent first data lines 41 far from the center of the through hole 10 in the direction perpendicular to the first data line 41, so as to increase the parasitic capacitance between the surrounding lines corresponding to two adjacent first data lines 41 close to the center of the through hole 10 in the direction perpendicular to the first data line 41, thereby increasing the total load of the first surrounding line and the first data line 41, and improving the display uniformity of the display panel 100.
When the line widths of the first and second loop windings are the same, the resistance of the first loop winding is greater than that of the second loop winding because the length of the first loop winding is greater than that of the second loop winding.
In order to avoid that the sum of the resistance of the first surrounding line and the resistance of the first data line 41 corresponding to the first surrounding line is greater than the sum of the resistance of the second surrounding line and the resistance of the first data line 41 corresponding to the second surrounding line due to the excessive resistance of the first surrounding line, in some embodiments, the line width of the first surrounding line may be set to be greater than the line width of the second surrounding line, so as to appropriately reduce the resistance of the first surrounding line, compensate the total load of the second surrounding line and the first data line 41 corresponding to the second surrounding line, and improve the display uniformity of the display panel 100.
In some embodiments, the through hole 10 area of the display panel 100 may be encapsulated by providing a barrier glue 50 surrounding at least a portion of the through hole 10 to prevent moisture or oxygen in the air from entering the inside of the display panel 100. The blocking glue 50 may be disposed on the surrounding line 43, or between the surrounding line and the through hole 10.
In the embodiment of the present application, the display panel 100 may further include another non-display area 60, and the non-display area 60 surrounds at least a portion of the display area 30. The non-display area 60 is used to set peripheral circuits of the display panel 100.
In view of the above, the display panel provided in the embodiment of the present application includes the through hole 10, the non-display area 20, the display area 30, and the data line 40; wherein the non-display area 20 surrounds at least a portion of the through hole 10; the display area 30 surrounds at least a portion of the non-display area 20; the data line 40 includes at least two first data lines 41, at least two second data lines 42, and at least two surrounding lines 43, the first data lines 41 and the second data lines 42 are located in the display region 30, the surrounding lines 43 are located in the non-display region 20 and are disposed around the through hole 10, the first data lines 41 include first straight portions 411 and second straight portions 412, and the first straight portions 411 are connected to the second straight portions 412 through the surrounding lines 43. According to the scheme, the first straight line parts 411 of at least two first data lines 41 are connected with the second straight line parts 412 through one surrounding line 43, so that the number of the surrounding lines 43 in the non-display area 20 is reduced, the size of the non-display area 20 is reduced, and the screen occupation ratio of the display panel 100 is increased.
In the foregoing embodiments, the descriptions of the respective embodiments have respective emphasis, and for parts that are not described in detail in a certain embodiment, reference may be made to related descriptions of other embodiments.
