When the signal lines are data lines extending along the column direction and arranged along the column direction, the special-shaped non-display area is positioned on at least one side edge of the left side and the right side of the display panel in the row direction. Or the display panel is provided with irregular non-display areas near the upper end, the lower end, the left side and the right side of the display panel, the data lines comprise conventional data lines and non-conventional data lines, the non-conventional data lines comprise first non-conventional signal lines, connecting lines and second non-conventional data lines, the grid lines comprise conventional grid lines and non-conventional grid lines, and the non-conventional grid lines comprise first non-conventional grid lines, connecting lines and second non-conventional grid lines. For example, the following may be set: the display panel comprises two special-shaped non-display areas, namely a first special-shaped non-display area and a second special-shaped non-display area, the first special-shaped non-display area is positioned at least one end of the display panel in the column direction, the second special-shaped non-display area is positioned at least one side of the display panel in the row direction, and the signal line comprises a plurality of grid lines extending in the row direction and arranged in the column direction and a plurality of data lines extending in the column direction and arranged in the row direction.
Fig. 10 is a partial schematic view of another display panel provided in the embodiment of the present invention, and the structure of the display panel provided in the embodiment is substantially similar to that of the display panel provided in the foregoing embodiment, except that: the line width of the connection line 21 is larger than the line width of the signal line 11. Specifically, taking the signal line 11 extending in the row direction as an example, the width of the signal line 11 in the column direction is the line width of the signal line 11, the width of the portion of the connection line 21 extending in the column direction in the row direction is greater than the line width of the signal line 11, the width of the portion of the connection line 21 extending in the row direction in the column direction is greater than the line width of the signal line 11, and the width of the portion of the connection line 21 extending in the column direction in the row direction is equal to the width of the portion of the connection line 21 extending in the row direction in the column direction, which is defined as the line width of the connection line 21.
In the display panel, since the regular signal lines 111 extend straight through the entire regular display region from left to right (or from right to left) along the row direction, and the first irregular signal line and the second irregular signal line are electrically connected by a connection line 21 bent around the irregular non-display region 110 to form a complete irregular signal line 112 extending through the entire display region from left to right (or from right to left), the length of each irregular signal line 112 is greater than that of each regular signal line 111. In the embodiment, by widening the line width of the connection line 21, it is ensured that the impedance of each unconventional signal line 112 is approximately equal to that of each conventional signal line 111 under the condition that the length of the unconventional signal line 112 is greater than that of each conventional signal line 111, so that the impedance of the signal lines on the whole display panel is uniformly set, and the problem of poor display of the display panel caused by unequal impedance of the signal lines is solved.
In other embodiments, the impedance of the signal lines on the entire display panel may be uniformly set by changing the material of the connection lines. For example, the following may be set: the resistivity of the material forming the connecting line is smaller than that of the material forming the signal line, so that the impedance of each unconventional signal line is approximately equal to that of each conventional signal line under the condition that the length of each unconventional signal line is larger than that of each conventional signal line.
