Detailed Description
The present invention will be described in further detail with reference to specific examples, but the present invention is not limited thereto.
Example one
Please refer to fig. 1, fig. 1 is a schematic structural diagram of a fan-out area wiring structure provided by an embodiment of the present invention, the fan-out area wiring structure in fig. 1 is applied to the fan-out area wiring design before the exposure and etching are performed on the fan-out area, and a plurality of fan-out lines with the same resistivity can be obtained by exposing and etching the wiring structure of this embodiment.
The fan-out routing structure in fig. 1 includes: a plurality of fan-out lines 101 arranged in parallel; and at least one dummy fan-out line 102, wherein the dummy fan-out line 102 and the fan-out line 101 are arranged in parallel, and the dummy fan-out line 102 is positioned in an area with smaller line density in the fan-out area.
Wherein, the linear density means: a plurality of fan-out lines which are arranged according to a certain rule are designed in the fan-out area, a certain area in the fan-out area is appointed, and the density of the fan-out lines in the area is the linear density.
For example, for the nth fanout line of the plurality of fanout lines, a first linear density and a second linear density exist in left and right side areas (or upper and lower side areas) of the nth fanout line, and the first linear density and the second linear density may be equal or different; when the first line density and the second line density are not equal, the area with the smaller line density is called a pattern sparse area, and the area with the larger line density is called a pattern dense area. Referring to fig. 2, fig. 2 is a schematic diagram of a pattern dense area and a pattern sparse area provided in an embodiment of the present invention, when the nth line is located at an outermost side of a plurality of fan-out lines, there is no fan-out line in an area on one side of the nth line, the line density of the area on the side is 0, the area is the pattern sparse area, there is a fan-out line in an area on the other side of the nth line, the line density of the area on the side is 100%, and the area is the pattern dense area; when the line width of the fan-out line is equal and the line spacing is equal, the line density of the fan-out line is 100% in the region which is 1 line spacing away from the left side and the right side of the n-number line; comparing the area of the nth line with the area of the (n-1) th line, wherein when the areas of the nth line and the (n-1) th line are equal, the linear density of the area of the nth line is less than that of the area of the (n-1) th line.
For another example, referring to fig. 3, fig. 3 is a schematic diagram of another pattern dense area and pattern sparse area provided by an embodiment of the present invention, in a conventional fan-out line design, a fan-out line is generally formed by connecting a straight line portion and a diagonal line portion, and in an area formed by a plurality of diagonal line portions, because a certain angle exists at a connection point between the diagonal line portion and the straight line portion, a line density of the diagonal line portion near a connection point between the diagonal line portion and the straight line portion is less than a line density of the diagonal line portion far away from the connection point, an area formed by a plurality of diagonal line portions near the connection point is referred to as a pattern sparse area, and an area formed by a plurality of diagonal line portions far.
Therefore, the area with low linear density and the area with high linear density of the embodiment of the present invention are not fixed and can be located at any position in the fan-out area, but the two areas are relatively speaking, and the area with low linear density and the area with high linear density are two adjacent areas.
In an embodiment, if the fan-out lines are arranged in parallel in sequence, and the line widths of the fan-out lines are all equal, and the line pitches of two adjacent fan-out lines are all equal, for one fan-out line on the outermost side, the line density on one side is 0, and the line density on one side is 100%, at this time, the dummy fan-out line is disposed in the area on one side where the line density is 0, that is, the dummy fan-out line 102 is located outside the fan-out lines 101, as shown in fig. 1. In the actual layout design, dummy fanout lines 102 are designed in the blank areas on both sides of the fanout lines. In this case, a line pitch w2 between the dummy fanout line 102 and the outermost fanout line 101 is equal to a line pitch w1 between two adjacent fanout lines 101, a line width d2 of the dummy fanout line 102 is equal to a line width d1 of the fanout line 101, and at this time, the line densities of both side areas of the outermost fanout line 101 are equal. Further, the line width of the dummy fanout line 101 may also be designed as the sum of the line width of the fanout line and Wd, where Wd is the line width loss difference between the pattern dense area and the pattern sparse area after exposure and etching. After exposure and etching, the dummy fan-out line is completely etched, and the display panel obtained finally does not have the dummy fan-out line; or the dummy fanout line may become thinner; in any case, the influence on the line width of the fan-out line in the original design is avoided.
In a specific embodiment, if the fan-out lines 101 are sequentially arranged in parallel, the line widths of the fan-out lines 101 are not equal, or the line distances between two adjacent fan-out lines 101 are not equal, due to the difference in line density between the areas with unequal line widths or line distances, the dummy fan-out line 102 is designed in the area with smaller line density, i.e., the pattern sparse area, so that the line density in the pattern sparse area is equal to or close to the line density in the pattern dense area. In this case, the line spacing between the dummy fanout line 102 and the adjacent fanout line 101 is smaller than the line spacing between two adjacent fanout lines 101, the line width of the dummy fanout line 102 is smaller than the line width of the fanout line 101, the dummy fanout line is completely etched after exposure and etching, and the dummy fanout line does not exist in the finally prepared display panel; or the dummy fanout line may become thinner; in any case, the influence on the line width of the fan-out line in the original design is avoided.

It should be noted that the dummy fan-out line is not limited to a line having a certain line width, and may be a block having a certain area, for example, dummy fan-out blocks may be disposed between the second line segments, and the dummy fan-out blocks may be disposed in a specific triangle according to a connection angle between the diagonal line portion and the straight line portion, so that the line density of the diagonal line portion is maintained to be uniform or close. Also, after etching, the dummy fan-out blocks disappear or become smaller.
