Description

显示面板
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。
背景技术
随着液晶面板技术的不断更新,小尺寸面板,特别是4-7寸的手机面板,正逐渐朝着超窄边框乃至无边框化发展,传统显示面板技术通过压缩阵列基板行驱动(Gate DriverOn Array,GOA)电路尺寸、缩小应用触控与显示驱动集成芯片(Touch and Display DriverIntegration,TDDI)的IC芯片以及缩小走线间的距离等方式来达成缩小边框,目前边框的宽度已经接近了0.7mm至0.8mm,然而为了保证GOA有效工作、面板的信赖性测试及各种信号线之间相互隔断,边框(特别是侧向边框)的压缩已经接近了极限。
故,有必要提供一种窄边框显示面板,以解决现有技术所存在的问题。
发明内容
本发明的目的在于提供一种显示面板,不但可以进一步的缩小侧向边框的宽度,还可以与现行制程工艺相容,进而降低后续沿生的改造成本或生产成本。
为达成本发明的前述目的,本发明提供一种显示面板,所述显示面板包括:

多个数据线,设置于所述透光基板上的所述主动显示区上;
多个扫描线,设置于所述透光基板上的所述主动显示区上,幷且所述多个扫描线垂直于所述多个数据线;及

根据本发明一实施例,所述显示面板还包括一绝缘层及一上透明导电层,所述绝缘层设置于所述多个引线上,所述上透明导电层设置于所述绝缘层上幷且电性连接所述数据线。
根据本发明一实施例,所述多个引线及所述透明导电层是由一透明导电材料所制成。
根据本发明一实施例,多个引线的其中之一不与所述多个数据线之一重合。
本发明还提供一种显示面板,所述显示面板包括:
一透光基板,所述透光基板上具有一半导体膜层结构,所述半导体膜层结构形成一主动显示区;
多个数据线,设置于所述透光基板上的所述主动显示区上;
多个扫描线,设置于所述透光基板上的所述主动显示区上,幷且所述多个扫描线垂直于所述多个数据线;及
多个引线,电性连接对应的所述多个扫描线,幷且所述多个引线平行于所述多个数据线。
根据本发明一实施例,所述半导体膜层结构包括:一第一金属层、一层间绝缘层、一第二金属层及一平坦化层,所述层间绝缘层设置于所述第一金属层与所述第二金属层之间,所述平坦化层设置于所述第二金属层上,且所述平坦化层具有多个导电孔。

根据本发明一实施例,至少一个所述多个引线设置于相邻的两个所述数据线之间,幷且多个引线的其中之一不与所述多个数据线之一重合。
本发明的有益效果为:利用图形化的透明导电材料作为引线,传递扫描线的信号,透明导电的引线不需要额外绕至边框,进而实现缩小显示面板的侧向边框。而且与现行的制程工艺高度相容,不需要增加额外的光罩及相关的光刻工艺步骤,可以降低后续沿生的改造成本或生产成本。此外,引线不与数据线重合还可以有效地降低寄生电容。
