In one embodiment, as shown with continued reference to fig. 2, the non-display area BA includes two second non-display areas BA2, and the number of the second connection lines M2 respectively disposed in the two second non-display areas BA2 is equal.

For example, the first connection line may be aligned with an extending direction of the conventional first signal line in the display area, or the first connection line may be routed around an edge of the through hole in the first non-display area. When the first connection line is routed around the edge of the through hole, a difference may occur between the total length of the first a signal line and the total length of the first b signal line which is conventionally arranged, and further, a difference may occur in resistance, which causes a difference in voltage drop when transmitting signals, and finally, a difference may occur in pixel display driven by the first a signal line and the first b signal line respectively.

The following examples will illustrate specific cases. It should be noted that the line widths referred to in the following embodiments all refer to the widths of lines, i.e., the widths in the direction perpendicular to the extending direction of the lines.

Fig. 3 also illustrates a case where the display panel includes the second connection line M2. Optionally, the display panel may not be provided with the second connection line.

The line width of the first a connection line M1a is d3, the line width of the first b signal line X1b is d2, and d3> d2. In this embodiment, the first a connection line is at least partially disposed around the through hole, which results in that the total length of the first a signal line jointly formed by the first a connection line and the first a sub-signal line becomes larger, that is, the total length of the first a signal line is larger than the total length of the first b signal line. Under the condition that the line width of the first A connecting line is not adjusted, the resistance of the first A signal line where the first A connecting line is located is increased, in the embodiment of the invention, the line width of at least part of line segments of the first A connecting line is larger than the line width of the first B signal line, and according to the resistance law: r = ρ L/S, where ρ is the resistivity of the material from which the wire is made, L is the wire length, S is the cross-sectional area of the wire, and R is the resistance value.

The respective line widths of the first connecting line M1a and the first second connecting line M1b are not shown in the drawing, and optionally, the line width of the first second connecting line M1b may be set to be equal to the line width of the first second signal line X1b, so that the resistance of the first signal line formed by the first second connecting line M1b and the first sub-signal line Z is ensured to be approximately equal to the resistance of the first second signal line; the line width of the first A connecting line M1a is set to be larger than the line width of the first B signal line X1b, the resistance of the first A connecting line M1a in unit length is reduced by increasing the line width of at least part of the line segment of the first A connecting line M1a, therefore, the resistance difference between the first A signal line and the first B signal line is balanced, and the resistance of the first A signal line formed by the first A connecting line and the first A sub signal line is ensured to be approximately equal to the resistance of the first B signal line. According to the embodiment, the voltage drop generated when the first A signal line and the first B signal line transmit signals can be approximately the same, and therefore the display brightness of the pixels driven by the first A signal line and the first B signal line is consistent.
Furthermore, the display panel further comprises a second signal line extending along the second direction and overlapping the first signal line in an insulating manner, so that a coupling capacitor exists at a position where the first signal line and the second signal line overlap in an insulating manner.

In this embodiment, the extending direction of the first second connecting line is the same as the extending direction of the first sub-signal line, and the line width of the first second connecting line is the same as the line width of the first second signal line, so that the resistance of the first signal line formed by the first second connecting line and the first sub-signal line can be ensured to be approximately equal to the resistance of the first second signal line, and further, the voltage drop generated when the first signal line and the first second signal line transmit signals can be ensured to be approximately equal. Further, the line width of the overlapped part of the first second connecting line in the second signal line is equal to the line width of the overlapped part of the first second signal line in the second signal line, and then the coupling capacitance generated by the insulated overlapping of the first second connecting line and the second signal line is approximately the same as the coupling capacitance generated by the insulated overlapping of the first second signal line and the second signal line, so that the display brightness consistency of pixels driven by the first signal line and the first second signal line is further ensured, and the display uniformity is ensured.
