Description

显示面板及其走线结构
【技术领域】
本发明涉及显示技术领域,特别是涉及一种显示面板及其走线结构。
【背景技术】
为了提高显示面板的显示品质,在显示面板中会尽量缩小金属走线之间的阻抗,为实现这一目标,可以采用改变金属走线的线宽达到。
如图1所示,图1是现有技术中显示面板的走线结构示意图。在显示面板的框胶涂布区域12设置有多条金属走线,以第N+1条金属走线、第N条金属走线和第N-1条金属走线为例,由于从第1条金属走线往第N条金属走线的方向(如图1中的箭头所示的方向A),金属走线的路程增加,也就是说第N+1条金属走线的路程比第N条金属走线的路程长,第N条金属走线的路程又比第N-1条金属走线的路程长。为了缩小金属走线之间的阻抗差异,沿着图1中的方向A,金属走线的宽度也相对增加,即:第N+1条金属走线的线宽比第N条金属走线的线宽大,第N条金属走线的线宽比第N-1条金属走线的线宽大。在各条金属走线之间的线距D保持不变的情况下,由于金属走线的宽度增加,因此在框胶涂布区域12中,沿着图1中的方向A,金属覆盖率增大,使得框胶涂布区域12透光率会变化,从而导致框胶固化不均匀,影响液晶面板的显示品质。
【发明内容】
本发明主要解决的技术问题是提供一种显示面板及其走线结构,能够使得设置在框胶涂布区域中的金属走线的金属覆盖率不变。

其中,在n的取值为不同数值时,设置在第二走线区域上的线宽a的取值与线距b的取值保持不变。
其中,在n的取值为不同数值时,设置在第二走线区域上的线宽a的取值与线距b的取值保持等比例变化。
其中,沿着从第一条金属走线至最后一条金属走线的第一分布方向,线宽a的取值与线距b的取值保持等比例增加。
其中,比例为1:1。
其中,沿着从最后一条金属走线至第一条金属走线的第二分布方向,线宽a的取值与线距b的取值保持等比例减小。
其中,比例为1:1。
其中,相邻金属走线的阻抗值相差不超过10%。
其中,沿着从第一条金属走线至最后一条金属走线的分布方向,在第一走线区域和第三走线区域上,随着n的取值增加,线宽a的取值变大,线距b的取值保持不变。
为解决上述技术问题,本发明采用的又一个技术方案是:提供一种显示面板,显示面板包括设置在其内的走线结构,走线结构包括:多条金属走线,金属走线延伸设置在连续分布的第一走线区域、第二走线区域和第三走线区域上;其中,第一走线区域位于第二走线区域的内侧,第三走线区域位于第二走线区域的外侧,第二走线区域为显示面板的框胶涂布区域,设置在第二走线区域上的第n条金属走线的线宽为a,第n条金属走线与第n+1条金属走线之间的线距为b,其中,n≧1,且在n的取值为不同数值时,a / (a+b)的比值保持不变。
其中,在n的取值为不同数值时,设置在第二走线区域上的线宽a的取值与线距b的取值保持不变。
其中,在n的取值为不同数值时,设置在第二走线区域上的线宽a的取值与线距b的取值保持等比例变化。

其中,沿着从第一条金属走线至最后一条金属走线的分布方向,在第一走线区域和第三走线区域上,随着n的取值增加,线宽a的取值变大,线距b的取值保持不变。
本发明的有益效果是:区别于现有技术的情况,本发明的显示面板及其走线结构通过将显示面板的框胶涂布区域中各金属走线的线宽a与线距b设置成满足a / (a+b)的比值保持不变的关系,由此能够使得设置在框胶涂布区域上的金属覆盖率不变,避免框胶固化不均匀,增强显示面板的稳定性,有效提高显示面板的显示品质。

具体而言,请参阅图4所示,图4是本发明的显示面板的走线结构的第一实施例的示意图。
本实施例中,以n的取值为2、3、4、5四个不同数值为例进行说明,即:以第2条金属走线n 2 、第3条金属走线n 3 、第4条金属走线n 4 和第五条金属走线n 5 为例。
其中,第2条金属走线n 2 包括设置在第一走线区域21的金属走线221、设置在第二走线区域22的金属走线222和设置在第三走线区域23上的金属走线223,且第2条金属走线n 2 设置在第二走线区域22的线宽为a 2 ,与第3条金属走线n 3 的线距为b 2
第3条金属走线n 3 包括设置在第一走线区域21的金属走线231、设置在第二走线区域22的金属走线232和设置在第三走线区域23上的金属走线233,且第3条金属走线n 3 设置在第二走线区域22的线宽为a 3 ,与第4条金属走线n 4 的线距为b 3
第4条金属走线n 4 包括设置在第一走线区域21的金属走线241、设置在第二走线区域22的金属走线242和设置在第三走线区域23上的金属走线243,且第4条金属走线n 4 设置在第二走线区域22的线宽为a 4 ,与第5条金属走线n 5 的线距为b 4
其中,a 2 = a 3 = a 4 ,b 2 = b 3 = b 4 ,则可以得到a 2 / (a 2 + b 2 )= a 3 / (a 3 + b 3 )= a 4 / (a 4 + b 4 )。
进一步的,第2条金属走线n 2 设置在第一走线区域21的线宽为a 5 ,且与第3条金属走线n 3 的线距为b 5 。第3条金属走线n 3 设置在第一走线区域21的线宽为a 6 ,且与第4条金属走线n 4 的线距为b 6 。第4条金属走线n 4 设置在第一走线区域21的线宽为a 7 ,且与第5条金属走线n 5 的线距为b 7 。其中,b 5 = b 6 = b 7 ,且a 7 > a 6 > a 5
第2条金属走线n 2 设置在第三走线区域23的线宽为a 8 ,且与第3条金属走线n 3 的线距为b 8 。第3条金属走线n 3 设置在第三走线区域23的线宽为a 9 ,且与第4条金属走线n 4 的线距为b 9 。第4条金属走线n 4 设置在第三走线区域23的线宽为a 10 ,且与第5条金属走线n 5 的线距为b 10 。其中,b 8 = b 9 = b 10 ,且a 10 > a 9 > a 8
由此可得在n的取值为不同数值时,设置在第二走线区域22上的线宽a的取值与线距b的取值保持不变,也就是a / (a+b)的比值保持不变。沿着从第一条金属走线至最后一条金属走线的分布方向(如图4中的箭头所示的方向X 1 ),在第一走线区域21和第三走线区域23上,随着n的取值增加,线宽a的取值变大,线距b的取值保持不变。
进一步参考图5,图5是本发明的显示面板的走线结构的第二实施例的示意图。同样,本实施例中,以n的取值为2、3、4、5四个不同数值为例进行说明,即:以第2条金属走线N 2 、第3条金属走线N 3 、第4条金属走线N 4 和第5条金属走线N 5 为例。
其中,第2条金属走线N 2 、第3条金属走线N 3 、第4条金属走线N 4 和第5条金属走线N 5 设置在第一走线区域31和第三走线区域33的线宽A和线距B与上述所述的相同,这里就不再一一赘述。
与上述主要区别在于:第2条金属走线N 2 设置在第二走线区域32的金属走线322的线宽为A 2 ,且与第3条金属走线N 3 的线距为B 2 ;第3条金属走线N 3 设置在第二走线区域22的金属走线332的线宽为A 3 ,且与第4条金属走线N 4 的线距为B 3 ;第4条金属走线N 4 设置在第二走线区域22金属走线342的线宽为A 4 ,且与第5条金属走线N 5 的线距为B 4
其中,A 4 = m* A 3 ;A 3 = m* A 2 ;且B 4 = m* B 3 ;B 3 = m* B 2 ;其中m为正数,由于A 4 / (A 4 + B 4 )= m* A 3 / (m* A 3 + m* B 3 )= A 3 / (A 3 + B 3 );而A 3 / (A 3 + B 3 )= m* A 2 / (m* A 2 + m* B 2 )= A 2 / (A 2 + B 2 ),由此可得,A 2 / (A 2 + B 2 )= A 3 / (A 3 + B 3 )= A 4 / (A 4 + B 4 )。由上可得,在N的取值为不同数值时,设置在第二走线区域32上的线宽A的取值与述线距B的取值保持等比例变化。
当m取值为大于或等于1时,沿着从第一条金属走线至最后一条金属走线的第一分布方向(如图5中的箭头所示的方向X 1 ),设置在第二走线区域32上的线宽A的取值与线距B的取值保持等比例增加。
当m取值大于0且小于1时,沿着从第一条金属走线至最后一条金属走线的第一分布方向(如图5中的箭头所示的方向X 1 ),设置在第二走线区域32上的线宽A的取值与线距B的取值保持等比例减小。即:沿着从最后一条金属走线至第一条金属走线的第二分布方向(与图5中的箭头所示的方向X 1 相反的方向),设置在第二走线区域32上的线宽A的取值与线距B的取值保持等比例增加。
其中,在本实施例中,比例优选设置为1:1,但在其他实施例中,比例还可以设置成其他,如1:0.8或2:1等,具体需要根据实际情况而定。
综上所述,本发明的显示面板及其走线结构通过将显示面板的框胶涂布区域中各金属走线的线宽a与线距b设置成满足a / (a+b)的比值保持不变的关系,由此能够使得设置在框胶涂布区域上的金属覆盖率不变,避免框胶固化不均匀,增强显示面板的稳定性,有效提高显示面板的显示品质。
以上所述仅为本发明的实施方式,并非因此限制本发明的专利范围,凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。
