具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明，本申请实施例中所有方向性指示（诸如上、下、左、右、前、后……）仅用于解释在某一特定姿态（如附图所示）下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
在本申请中，除非另有明确的规定和限定，术语“连接”、“固定”等应做广义理解，例如，“固定”可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
另外，在本申请中如涉及“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本申请要求的保护范围之内。
显示面板包括包含有多个画素的主动区以及主动区外围的外部引线结合区，主动区内设置的多个画素用以画面显示，外部引线结合区设有驱动芯片，驱动芯片需要通过走线连接至主动区，以驱动主动区的显示。由于驱动芯片传输信号部分与对应的主动区传输信号部分在宽度上有差异，因此这部分走线形成扇形走线的结构。
具体为，主动区包括多条扫描线和多条数据线，多条所述扫描线和多条所述数据线相交设置在主动区内，以形成多个画素单元。驱动芯片的引脚需要通过扇形的走线连接至扫描线或数据线。一般而言，扇形走线中，处于中心的走线的长度最短，位于两侧的走线的长度最大，长度的差异导致了各走线之间的阻抗存在差异，而且走线的长度差异越大，阻抗的差异也越大。因此为了减少各走线的长度的差异，需要对每条走线的形状/结构进行更改，以便使得各走线的长度趋向一致，以保证各走线的阻抗差异最小。但是，改变了走线的形状，走线所占据的面积也同时增大，在空间受限的情况下，不利于各走线的布置，从而难以确保各走线的阻抗差异达到最小，甚至消失。
因此，本申请提出一种扇出走线结构。
在本申请一实施例中，参照图1至图4所示，所述扇出走线结构包括：
第一扇出层100和第二扇出层200；以及，
绝缘层300，所述绝缘层300设于所述第一扇出层100和所述第二扇出层200之间，所述第一扇出层100、所述绝缘层200和所述第二扇出层300由上而下排布；
所述第一扇出层100包括多条第一走线110，多条所述第一走线110间隔排列；所述第二扇出层200包括多条第二走线210，多条所述第二走线210间隔排列；
所述第一走线110和所述第二走线210交替设置，相邻的所述第一走线110和所述第二走线210部分重叠。
在本实施例中，所述第一扇出层100包括多条第一走线110，所述第二扇出层200包括多条第二走线210，所述第一走线110和所述第二走线210通过所述绝缘层300实现绝缘，保证所述第一走线110和所述第二走线210之间不会短路，从而避免信号传输受到干扰。
所述绝缘层300为采用绝缘材质制备而成，绝缘材质可根据实际需求进行选择。所述绝缘层300和所述第一扇出层100、所述第二扇出层200可结合为一体，更保证所述第一走线110和所述第二走线210结构稳定，防止所述第一走线110和所述第二走线210的断裂。所述第一扇出层100、所述绝缘层300和所述第二扇出层200结合为一体可以为先制备出所述第二走线210形成所述第二扇出层200，再于所述第二扇出层200上制备成型出所述绝缘层300，再于所述绝缘层300上制备所述第一走线110形成所述第一扇出层100，如此，将所述第一扇出层100、所述绝缘层300和所述第二扇出层200结合为一体。
具体为，该扇出走线结构可成型于基板上。先于基板上成型出所述第二走线210，再于所述第二走线210上成型出所述绝缘层300，最后于所述绝缘层300上成型出所述第一走线110。如此，所述第一走线110、所述绝缘层300、所述第二走线210和所述基板结合为一体，所述扇出走线结构附着于所述基板上。
多条所述第一走线110间隔排列，以保证相邻的所述第一走线110之间的绝缘，相邻的所述第一走线110的距离可以根据实际需求而设定，本实施例不做限定。与多条所述第一走线110间隔排列类似，多条所述第二走线210间隔排列，以保证相邻的所述第二走线210之间的绝缘，相邻的所述第二走线210的距离可以根据实际需求而设定，本实施例不做限定。
所述第一走线110和所述第二走线210交替设置，相邻的所述第一走线110和所述第二走线210部分重叠。如此，通过所述第一扇出层100和所述第二扇出层200这两层的结构，相邻的所述第一走线110和所述第二走线210部分重叠，因此可以缩小扇出走线结构所占据的长度方向的空间（该长度方向即为所述第一走线110或所述第二走线210由中间向两侧布置的方向）。
也即，在扇出走线结构所占据的长度方向的空间不变的情况下，相当于将所述扇出走线结构的走线分为所述第一走线110和所述第二走线210，并将所述第一走线110和所述第二走线210置于两层结构中。因此，在沿所述扇出走线结构的长度方向，不同的所述第一走线110和所述第二走线210可以具有更多的空间进行走线的形状设计，从而可以调节不同的所述第一走线110和所述第二走线210的阻抗差异。即使对于每条所述第一走线110和所述第二走线210所占据的空间有所增大，但是通过两层结构以及重叠设置，也能降低所述扇出走线结构的占用空间。
本实施例中通过扇出走线结构包括所述第一走线110和所述第二走线210，所述第一走线110和所述第二走线210交替设置，相邻的所述第一走线110和所述第二走线210部分重叠，且所述第一走线110和所述第二走线210相互绝缘。如此，通过至少两层的结构设置，即所述第一扇出层100和所述第二扇出层200，在空间受到压缩的时候，由于所述第一扇出层100和所述第二扇出层200是叠合设置，所述第一走线110和所述第二走线210设计空间得到大大增加，从而由中心到侧边，可以调整不同的所述第一走线110和所述第二走线210的长度达到一致，从而保证所述第一走线110和所述第二走线210的阻抗差异达到最低，甚至消失，保证信号传输的稳定。
在本申请一实施例中，参照图1和图2所示，所述第一走线110包括绕线段111和直线段112，多条所述第一走线110呈中间向两侧布置，且沿中间至两侧的方向，所述第一走线110的绕线段111的延伸长度逐渐减小，所述第一走线110的直线段112的延伸长度逐渐增大。
在本实施例中，所述第一走线110包括绕线段111和直线段112，所述第一走线的绕线段111设置为与驱动电路的针脚电连接，其直线段112设置为与主动区内的数据线或者信号线电连接。所述第一走线的绕线段111可以绕制不同的形状，如绕制呈折线形，或绕制呈弓形，所述第一走线的直线段112对应为直线。在本实施例中，各所述第一走线的绕线段111所绕制的形状一致，如此，提高所述第一走线110的制备效率。
多条所述第一走线110由中间向两侧布置，且沿中间至两侧的方向，所述第一走线的绕线段111的延伸长度逐渐减小，也即对应的走线长度逐渐减小，所述第一走线的直线段112的延伸长度逐渐增大，也即对应的走线长度逐渐增大。在有限的空间中，所述第一走线的绕线段111的延伸程度逐渐减小，对应的第一走线的直线段112的延伸长度也同步增大。如此，通过所述第一走线的绕线段111的走线长度调整和所述第一走线的直线段112的走线长度调整，以保证各所述第一走线110的走线长度趋向于一致，从而减小各所述第一走线110的阻抗差异。
在本申请一实施例中，参照图1至图3所示，所述第二走线210包括绕线段211和直线段212，多条所述第二走线210呈中间向两侧布置，且沿中间至两侧的方向，所述第二走线的绕线段211的延伸长度逐渐减小，所述第二走线的直线段212的延伸长度逐渐增大。
在本实施例中，如同所述第一走线110，所述第二走线210包括绕线段211和直线段212，所述第二走线的绕线段211设置为与驱动电路的针脚电连接，其直线段212设置为与主动区内的数据线或者信号线电连接。所述第二走线的绕线段211可以绕制不同的形状，如绕制呈折线形，或绕制呈弓形，所述第二走线的直线段212对应为直线。在本实施例中，各所述第二走线的绕线段211所绕制的形状一致，如此，提高所述第二走线210的制备效率。
多条所述第二走线210由中间向两侧布置，且沿中间至两侧的方向，所述第二走线的绕线段211的延伸长度逐渐减小，也即对应的走线长度逐渐减小，所述第二走线的直线段212的延伸长度逐渐增大，也即对应的走线长度逐渐增大。在有限的空间中，所述第二走线的绕线段211的延伸程度逐渐减小，对应的第二走线的直线段212的延伸长度也同步增大。如此，通过所述第二走线的绕线段211的走线长度调整和所述第二走线的直线段212的走线长度调整，以保证各所述第二走线210的走线长度趋向于二致，从而减小各所述第二走线210的阻抗差异。
在本申请一实施例中，参照图1至图3所示，所述第一走线的绕线段111的延伸长度大于与之相邻的所述第二走线的绕线段211的延伸长度；所述第一走线的直线段112的延伸长度小于与之相邻的所述第二走线的直线段212的延伸长度；
或，所述第一走线的绕线段111的延伸长度小于与之相邻的所述第二走线的绕线段211的延伸长度；所述第一走线的直线段112的延伸长度大于与之相邻的所述第二走线的直线段212的延伸长度。
在本实施例中，通过如上设置，即在中间向两侧的方向上，所述第一走线的绕线段111对应的走线长度和所述第二走线的绕线段211对应的走线长度依次减小，所述第一走线的直线段112对应的走线长度和所述第二走线的直线段212对应的走线长度依次增大。也即，对于所述第一走线的绕线段111和所述第二走线的绕线段111，越靠近中间，相应的绕线段的延伸长度越大（即绕线段对应的走线长度越长）；对于所述第一走线的直线段112和所述第二走线的直线段212，越靠近中间，相应的直线段的延伸长度越小（即直线段对应的走线长度越小）。如此，保证了各所述第一走线110和各所述第二走线210的阻抗差异达到最小。
在本申请一实施例中，参照图1所示，所述第一走线的绕线段111的延伸方向垂直于所述第一扇出层100的长度方向，所述第一走线的直线段112的延伸方向倾斜于所述第一扇出层100的长度方向；
所述第二走线的绕线段211的延伸方向垂直于所述第二扇出层200的长度方向，所述第二走线的直线段212的延伸方向倾斜于所述第二扇出层200的长度方向。
在本实施例中，所述第一扇出层100的长度方向即为所述第一走线110一侧至另一侧的方向。如此，将所述第一走线的绕线段111的延伸方向垂直于所述第一扇出层100的长度方向，以在占用最小空间的前提下延长相应的走线长度，将所述第一走线的直线段112的延伸方向倾斜于所述第一扇出层100的长度方向，以便于与数据线或信号线连接。
对于所述第二走线210，与所述第一走线110类似，不再重复赘述。
在本申请一实施例中，参照图1至图3所示，所述第一走线的绕线段111的宽度与所述第二走线的绕线段211的宽度相同。
在本实施例中，所述第一走线的绕线段111的宽度和所述第二走线的绕线段211的宽度相同时，也即当所述第一走线的绕线段111的延伸长度和所述第二走线的绕线段211的延伸长度发生变化时，阻抗即随之变化。因此在固定所述第一走线绕线段111和所述第二走线绕线段211的宽度时，通过调整相应绕线段的延伸长度即可调节阻抗，而不必同时调整所述第一走线的绕线段111和所述第二走线的绕线段211的宽度和延伸长度，以提高生产效率。
在本申请一实施例中，参照图1至图3所示，所述第一走线的绕线段111形成有引脚101，所述第二走线的绕线段211形成有引脚201，相邻的所述第一走线的引脚101与所述第二走线的引脚201的距离为P，相邻的所述第一走线的绕线段111之间的距离和相邻的所述第二走线的绕线段211之间的距离分别为S，所述第一走线的绕线段111的宽度和所述第二走线的绕线段211的宽度分别为W，且满足p＜w≤2p-s。
若相邻的所述第一走线110和所述第二走线210非重叠，那么宽度W则满足W=P-S。在本实施例中，通过相邻的所述第一走线110和所述第二走线210部分重叠，使得所述第一走线的绕线段111的宽度和所述第二走线的绕线段211的宽度W满足p＜w≤2p-s，相对于非重叠设置，宽度W大大增加，因此能增加所述第一走线的绕线段111和所述第二走线的绕线段211的走线路径，以更好地调节阻抗。而且，通过宽度W满足p＜w≤2p-s，以降低电容负荷，通过降低电容负荷，从而降低了信号延时。
在本申请一实施例中，所述绝缘层300为氮硅化合物层。
在本实施例中，氮硅化合物层（SiNx）能提供良好的绝缘性能，确保第一扇出层和所述第二扇出层的相互绝缘。
本申请还公开了一种显示面板。
在本申请一实施例中，所述显示面板包括如上所述的扇出走线结构。
在一实施例中，该显示面板包括驱动芯片和包含画素的主动区，所述扇出走线结构分别电连接所述驱动芯片和所述主动区。该扇出走线结构的具体结构参照上述实施例，由于本实施例中的所述显示面板的扇出走线结构采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有效果，在此不再一一赘述。

以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
