Description

显示装置 技术领域
本发明涉及液晶显示技术领域，尤其涉及一种显示装置。
 背景技术
目前，很多触控屏需要设置扇出区将显示区的数据信号引出，由于扇出区相对显示区的区域较小，而需要引出的扇出区输出端信号线数量较多，在将显示区的数据信号线引出时，这对于扇出区布线工艺有很大的要求。
如图1至5所示，目前带触控功能的主流显示屏多采用异形设计来提高显示屏占整个面板的比率，由于拐角处、由于需要阶梯状摆级传电路，导致左右边框的级传电路输出信号端到显示区的栅极线（Gate Line）之间需要留出一部分空间用来将金属走线连接到栅极线，此部分金属走线为扇出走线（Gate Fanout），扇出走线通常会占用面板左右边框一部分空间，导致左右边框的电路向切割线靠近，影响到显示装置信赖性及防静电能力等特性。

所述显示面板包括显示区210与非显示区29，所述非显示区29围绕所述显示区210。所述非显示区29包括芯片区24和弯折区213。所述弯折区213连接在所述芯片区24和所述显示区210之间。
所述驱动芯片27对应分布于所述非显示区29中的所述芯片区24中。本实施例中，所述显示区29为方形，如长方形或正方形，其具有若干拐角（一般是4个拐角），因此，所述芯片区24对应的具有至少一拐角区41以及直条形区42（也可称为边框区），如图11和12所示，在所述拐角区，所述驱动芯片阶梯状分布于所述芯片区24中；在所述直条形区42，所述驱动芯片沿所述直条形区的直线方向层级排列。
如图7所示，所述显示装置还包括若干信号线28。所述信号线28分布于所述显示区210并延伸至所述弯折区213中，所述弯折区213中的所述信号线28用来与所述驱动芯片27相连接。
为了实现减少扇出线26所需排布空间的效果，因此，本发明将所述扇出线26从所述显示装置的弯折区213中引出，将引出部分或者全部的扇出线26设置在所述驱动芯片27的上方并与所述驱动芯片27连接。
本实施例中，所述扇出线26采用的是在所述显示装置的内部走线，如图8所示，其中，所述显示装置包括玻璃基板31、遮光层39、第一绝缘层32、第二绝缘层33、有源层310、栅极绝缘层34、第三绝缘层35、栅极走线311、源漏极走线312、有机层36。其中，所述遮光层39设于所述玻璃基板31上，所述第一绝缘层32覆于所述遮光层39和所述玻璃基板31上；所述第二绝缘层33覆于所述第一绝缘层32上；所述有源层310设于所述第二绝缘层33上且对应于所述显示区210，并与所述遮光层39对应。所述有源层310具有源极区310a和漏极区310b；所述栅极绝缘层34覆于所述有源层310和所述第二绝缘层33上；所述栅极走线311设于所述栅极绝缘层34上；所述第三绝缘层35覆于所述栅极走线311和所述栅极绝缘层34上；所述源漏极走线312设于所述第三绝缘层35上；其中在所述显示区210，所述源漏极走线312对应连接至所述源极区310a和所述漏极区310b。本实施例中，利用所述源漏极走线312作为与所述扇出线26连接的信号线28。具体实施时，将所述有机层36覆于所述第三绝缘层35上后，再开设对应的连接孔37，所述连接孔37对应于所述弯折区213，且从所述有机层36贯穿至所述源漏极走线312的表面。之后在所述有机层36上沉积一金属走线313，在所述弯折区213中，所述金属走线313对应地通过所述连接孔37并连接至所述源漏极走线312；之后所述第四绝缘层38覆于所述有机层36和所述金属走线313的上表面。本实施例中，所述扇出线即为显示装置内部的金属走线313及其延伸至驱动芯片上方的走线。
本实施例中，将所述扇出线26设置为对应所述弯折区213的所述金属走线313。通过将扇出线26全部或部分地设置于所述弯折区213内。在所述边框区42、以及拐角41和43处使用本发明的扇出区排线布局，可以有效地减少驱动芯片到切割线的距离；这样可以减小所述扇出线26的空间，提高显示装置的信赖性（RA）及防静电（ESD）特性能力。
在本实施例的所述显示装置中，与所述弯折区213的扇出线26连接的所述信号线28之间相互平行。所述信号线28为显示装置中弯折区213的源极走线312a或者漏级走线312b。本发明是通过将源漏极走线312电性连接栅极走线311作为显示区210的信号线，另外在其他实施例当中，可以用单独的源漏极走线312作为所述显示区210的信号线28，也可以单独的用栅极走线311作为所述显示区210的信号线28，这并不影响本发明的创新点。而在所述显示区的源漏极走线用于驱动显示区的显示作用。
所述显示装置弯折区210的源极走线互相平行设置，即为本发明所述显示区210的信号线28，信号线28包括多条数据线、多条扫描线，所述数据线相互平行设置，所述扫描线垂直于所述数据线并且平行设置，所述数据线与扫描线交错形成网状结构。驱动芯片27通过金属走线313连接弯折区213的源漏极走线312，所述显示区数据线连接弯折区的漏级走线312b，所述显示区的扫描线连接弯折区的栅极走线311，而所述显示区的源极312a连接像素电极，主要用于对显示屏驱动液晶显像作用，使显示区可以正常的呈像。
所述非显示区210包括芯片区24以及连接在所述芯片24区和所述显示区210之间的弯折区213；所述驱动芯片27分布于所述芯片区24中；信号线28延伸至所述弯折区213，所述扇出线26的一端对应连接至所述弯折区213的所述信号线28。这样可以使驱动芯片27的信号传送至显示区210，可以使显示区210正常工作显示。
如图9所示，所述驱动芯片27设有至少一信号输出端211；用于连接所述的扇出线26，将所述驱动芯片27的信号通过所述扇出线26传递至所述显示区210的所述信号线28。所述扇出线26一端对应连接至所述驱动芯片27的一信号输出端，其另一端对应连接至所述信号线28；所述扇出线26全部或部分地设置于所述驱动芯片27的上方。这样可以减少扇出线的空间，可以使驱动芯片27 远离切割线25，进一步提高显示装置的信赖性（RA）及防静电（ESD）特性能力，以及降低了实际制程的难度。
所述芯片区24的正上方具有所述扇出线26的走线区212，所述信号输出端211设于所述芯片区24朝向所述走线区212的一面。在所述驱动芯片27上，所述信号输出端211设于远离所述弯折区213的一侧。在所述走线区212，所述扇出线26呈“Z”字形来回排列。所述扇出线26“Z”字形排列，增加了扇出线的长度，这样有利于增加扇出线26的阻抗。
如图10、11所示，所述非显示区的边缘具有切割线，在所述芯片区，所述驱动芯片位于远离所述切割线的一侧。由于现很多屏幕都制作成不规则的屏幕，并带有特有的形状结构，一般都会带有多个拐角，其中，拐角41和42使用本发明的扇出区排线布局，驱动芯片27阶梯分布在拐角41处，使扇出线26部分或者全部设在驱动芯片27上，可以有效地减少边框距离；使驱动芯片27远离切割线25，也可以提高显示装置的RA 及ESD 特性能力。
如图12所示，边框区42使用本发明的扇出区排线布局，驱动芯片27线性分布在拐角41处，使扇出线26部分或者全部设在驱动芯片27上，可以有效地减少边框距离；使驱动芯片27远离切割线25，也可以增加提高显示装置的RA 及ESD 特性能力。
本发明的显示装置当然还可以包括如封装框等其他结构，由于本案的主要设计要点在所述扇出线的空间排布情况，即本实施例中的所述显示装置通过将扇出线26全部或部分地设置于所述驱动芯片27的上方。在所述边框区42、以及拐角41和43处使用本发明的扇出区排线布局，可以有效地减少边框距离；这样可以减小扇出线的空间，可以使驱动芯片27 远离切割线25，提高显示装置的RA 及ESD 特性能力。
以上对本发明实施例提供的显影方法以及金属层的图形化处理方法进行了详细介绍，本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明。同时，对于本领域的技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本发明的限制。
