The display panel 100 includes a display area AA disposed around the periphery of the first non-display area NA1 and a first non-display area NA 1. In some embodiments, the display panel 100 may further include a second non-display area NA2, the second non-display area NA2 being disposed around the periphery of the display area AA.
In some embodiments, the first non-display area NA1 may be configured as a light-permeable area, wherein the display panel 100 may be provided with an aperture structure at the first non-display area NA1, or each film layer of the display panel 100 at the first non-display area NA1 may be provided as a light-transmissive film layer. When the first non-display area NA1 is configured as a transparent area, the display panel 100 may integrate a photosensitive component on the back side (the side opposite to the display side) of the first non-display area NA1, so as to realize the under-screen integration of the photosensitive component such as a camera, and reduce the width of the other non-display area (the second non-display area NA2) at the periphery of the display area AA, thereby increasing the display area ratio of the display panel 100.
In the present embodiment, the first non-display area NA1 is illustrated as being square, but in other embodiments, the first non-display area NA1 may be other polygons such as a triangle, a rectangle, and a hexagon, or may be other shapes including curved boundaries such as a circle, an ellipse, and a fan. In this embodiment, the first non-display area NA1 is disposed near the corner area of the display panel 100, and in other embodiments, the first non-display area NA1 may be disposed near other areas, for example, near the midpoint of a side of the display panel 100.
As shown in fig. 2, the display panel 100 includes a plurality of first signal lines 110. The plurality of first signal lines 110 are disposed in the display area AA, and the first signal lines 110 are used for transmitting first signals. The display panel 100 is, for example, an OLED display panel, and the first signal is any one of a Scan (Scan) signal, an emission (Emit) signal, or a data (Date) signal. The plurality of first signal lines 110 include a plurality of first type signal lines 110a and a plurality of second type signal lines 110 b.
Each of the first-type signal lines 110a includes a first line segment 111a, a second line segment 112a, and a third line segment 113a electrically connected in sequence. The first line segment 111a and the third line segment 113a extend along the first direction and are respectively disposed on two sides of the first non-display area NA1 along the first direction X, and at least a part of the second line segment 112a is disposed around an outer periphery of the first non-display area NA 1. The second line segment 112a may be a polygonal line structure, and may also be a curved line structure in some embodiments.
Each second-type signal line 110b includes a fourth line segment 111b, a fifth line segment 112b, and a sixth line segment 113b electrically connected in sequence. The fourth line segment 111b, the fifth line segment 112b and the sixth line segment 113b all extend along the first direction X. The first line segments 111a of the first type signal lines 110a and the fourth line segments 111b of the second type signal lines 110b are arranged along a second direction Y, which intersects the first direction X. For example, in the present embodiment, the second direction Y is perpendicular to the first direction X. Accordingly, the third line segments 113a of the first type signal lines 110a and the sixth line segments 113b of the second type signal lines 110b are arranged along the second direction Y. The resistance per unit length of the fifth line segment 112b is greater than the resistance per unit length of the second line segment 112 a.
According to the display panel 100 of the embodiment of the invention, the fourth line segment 111b, the fifth line segment 112b, and the sixth line segment 113b of the second-type signal line 110b all extend along the first direction X, and at this time, the extension length of the second line segment 112a of the first-type signal line 110a is greater than the extension length of the fifth line segment 112b of the second-type signal line 110 b. Meanwhile, the resistance per unit length of the fifth line segment 112b is greater than that of the second line segment 112a in the embodiment of the present invention, so that the respective resistive loads of the fifth line segment 112b and the second line segment 112a tend to be consistent although the extension lengths thereof are different, and further, the total resistive load of the first-type signal line 110a and the total resistive load of the second-type signal line 110b tend to be consistent, thereby reducing the display difference caused by the difference between the two resistive loads.
In some embodiments, the length of the fifth line segment 112b of each second-type signal line 110b along the first direction X is the same as the span of the second line segment 112a of at least one first-type signal line 110a along the first direction X and corresponds to the position of the display panel 100 along the first direction X, so that the display effect of the display panel 100 in the corresponding area of the fifth line segment 112b is substantially the same as the display effect in the corresponding area of the second line segment 112a, and the uniformity of the display effect of the display panel 100 is improved. The span of the second line segment 112a of the first-type signal line 110a along the first direction X refers to the distance between two opposite ends of the second line segment 112a along the first direction X.
In some embodiments, in the second type signal line 110b, the resistance per unit length of the fifth line segment 112b is greater than the resistance per unit length of the fourth line segment 111b and the resistance per unit length of the sixth line segment 113 b.
As shown in fig. 2, in the embodiment, in the second-type signal line 110b, the fourth line segment 111b, the fifth line segment 112b, and the sixth line segment 113b are made of the same material, wherein the line width of the fifth line segment 112b is smaller than the line width of the fourth line segment 111b and the line width of the sixth line segment 113b, so that the fourth line segment 111b, the fifth line segment 112b, and the sixth line segment 113b of the second-type signal line 110b can be disposed on the same layer and simultaneously formed through the same patterning process, and the unit length resistance of the fifth line segment 112b is larger than the unit length resistance of the fourth line segment 111b and the unit length resistance of the sixth line segment 113b on the basis of saving process steps.
With continued reference to fig. 2, in some embodiments, the display panel 100 further includes a first capacitive coupling structure 130. The first capacitive coupling structures 130 are disposed at an insulating interval from the second type signal lines 110b, and the orthographic projection of the first capacitive coupling structures 130 on the display surface of the display panel 100 overlaps the orthographic projection of the fifth line segments 112b on the display surface of the display panel 100, so as to increase the capacitive load of the second type signal lines 110b at the fifth line segments 112b, thereby facilitating the configuration of the capacitive load of the second type signal lines 110b at the fifth line segments 112b to be substantially the same as the capacitive load of the first type signal lines 110a at the second line segments 112a, further enabling the display effect of the display panel 100 at the corresponding area of the fifth line segments 112b to be substantially the same as the display effect at the corresponding area of the second line segments 112a, and further improving the uniformity of the display effect of the display panel 100.
In some embodiments, the first capacitive coupling structure 130 is electrically connected to a fixed potential, so as to prevent the first capacitive coupling structure 130 from generating an electrostatic concentration phenomenon, thereby preventing a display problem and a problem of affecting a manufacturing yield caused by the electrostatic concentration at the first capacitive coupling structure 130.
In some embodiments, the display panel 100 includes a power supply signal structure, and the first capacitive coupling structure 130 is electrically connected to the power supply signal structure. Taking the display panel 100 as an example of an OLED, it includes an anode power supply signal structure for supplying a driving current (VDD) signal to a light emitting element of the OLED. The power supply signal structure of the display panel 100 may be a single-layer structure, or may be a double-layer or multi-layer structure. Since the power supply signal structure is usually at a fixed potential, the first capacitive coupling structure 130 is electrically connected to the power supply signal structure, so that the first capacitive coupling structure 130 is electrically connected to the fixed potential, and the electrostatic concentration phenomenon at the first capacitive coupling structure 130 is avoided by the convenient connection structure.
In some embodiments, the first capacitive coupling structure 130 includes at least one first redundant line segment 131 arranged at intervals along the first direction X, and a forward projection of each first redundant line segment 131 on the display surface of the display panel 100 overlaps with a forward projection of the fifth line segment 112b on the display surface of the display panel 100. Wherein, each of the first redundant line segments 131 and the fifth line segment 112b are coupled to form a capacitive load with a preset size. Therefore, when the capacitive load with the preset size needs to be increased, the first capacitive coupling structure 130 may include one first redundant line segment 131, and the first capacitive coupling structure 130 is configured into a plurality of first redundant line segments 131, so that the structure of the first capacitive coupling structure 130 can be accurately configured according to the required capacitive load, the accurate compensation of the capacitive load of the fifth line segment 112b is improved, and the uniformity of the display effect of the display panel 100 is further improved.

Each of the first-type signal lines 110a includes a first line segment 111a, a second line segment 112a, and a third line segment 113a electrically connected in sequence. The first line segment 111a and the third line segment 113a extend along the first direction and are respectively disposed on two sides of the first non-display area NA1 along the first direction X, and at least a part of the second line segment 112a is disposed around an outer periphery of the first non-display area NA 1.

The first line segments 111a of the first type signal lines 110a and the fourth line segments 111b of the second type signal lines 110b are arranged along a second direction Y, which intersects the first direction X. The resistance per unit length of the fifth line segment 112b is greater than that of the second line segment 112a, so that the respective resistive loads of the fifth line segment 112b and the second line segment 112a tend to be consistent although the extension lengths of the fifth line segment and the second line segment are different, and further, the total resistive load of the first-type signal line 110a and the total resistive load of the second-type signal line 110b tend to be consistent.

The first capacitive coupling structure 130 is disposed at an insulating interval from the second-type signal line 110b, and an orthographic projection of the first capacitive coupling structure 130 on the display surface of the display panel 100 overlaps an orthographic projection of the fifth line segment 112b on the display surface of the display panel 100, so as to increase a capacitive load of the second-type signal line 110b at the fifth line segment 112b, thereby facilitating configuration of the capacitive load of the second-type signal line 110b at the fifth line segment 112b to be substantially the same as the capacitive load of the first-type signal line 110a at the second line segment 112 a.
In order to clearly show the detailed structure of the display panel, only a portion of the first-type signal lines 110a and a portion of the second-type signal lines 110b are shown in fig. 3, and not all of the first signal lines 110 are shown.

In each group of the first-type signal lines 110a, along the arrangement direction in which the first line segments 111a of the plurality of first-type signal lines 110a are gradually away from the center of the first non-display area NA1, the extending lengths of the corresponding connected second line segments 112a are increased or decreased (for example, decreased in the present embodiment) so as to adapt to the boundary shape of the first non-display area NA1 for wiring the second line segments 112 a. Optionally, in each group of the first-type signal lines 110, the extension lengths of the second line segments 112a of the first-type signal lines 110a are different from each other.

In some embodiments, the extension lengths of the second line segments 112a of the plurality of first-type signal lines 110a are different, so that there is the first-type signal line 110a with the largest capacitive load of the second line segment 112a (for example, the first-type signal line 110a with the largest extension length of the second line segment 112 a), and the total capacitive load of the first-type signal line 110a is usually the largest. At this time, the second capacitive coupling structure 140 may be disposed at the second line segment 112a of the first-type signal line 110a except the first-type signal line 110a with the largest total capacitive load, and at the same time, the first capacitive coupling structure 130 is disposed at the fifth line segment 112b of the second-type signal line 110b, so that the capacitive loads of the second-type signal line 110b and the first-type signal line 110a except the first-type signal line 110a with the largest total capacitive load can be compensated by the same compensation value as that of the first-type signal line 110a with the largest total capacitive load, thereby improving the uniformity of the display of the entire display panel.

Wherein, each of the second redundant line segments 141 and the second line segment 112a are coupled to form a capacitive load of a preset size. Therefore, when the capacitive load with the preset size needs to be increased, the second capacitive coupling structure 140 may include one second redundant line segment 141, and the second capacitive coupling structure 140 is configured into a plurality of second redundant line segments 141, so that the structure of the second capacitive coupling structure 140 can be accurately configured according to the required capacitive load, and the accurate compensation of the capacitive load of the second line segment 112a is improved.
