When the width of the conductive line is increased, that is, the area S of the conductive line is increased, the resistance R of the conductive line is inversely proportional to the area of the conductive line, that is, by increasing the width of the conductive line, the resistance of the conductive line can be reduced. In the fan-out wire group 210, the first wire 2110 is farther away from the center line 500 of the display portion 100 than the second wire 2120, so that the length of the wire is longer, and when other conditions are consistent, the impedance of the first wire 2110 will be greater than that of the second wire 2120. By setting the width W1 of the second wire segment of the first trace to be greater than or equal to the width W2 of the second wire segment of the second trace, and setting the width W2 of the second wire segment of the second trace to be greater than the widths of the first trace 2110 and the second trace 2120 in other segments, the impedance of the second wire segment 2002 of the first trace 2110 can be made smaller than the impedance of the second wire segment 2002 of the second trace 2120, so that the overall impedance of the first trace 2110 is further reduced, the impedance of the first trace 2110 is made smaller than the impedance of the second trace 2120, and the influence of the trace in the fan-out area on the transmission of signals is reduced.
In this embodiment, the width W1 of the second wire segment of the first trace is set to be greater than or equal to the width W2 of the second wire segment of the second trace, so as to realize a narrow frame and reduce the trace impedance of the fan-out area.
