Description

一种柔性显示装置 技术领域
本发明涉及显示技术领域，尤其是，其中的一种柔性显示装置。
 背景技术
已知，窄边框显示屏由于具有高的屏占比受到用户的青睐，也成为显示面板企业研发的重点。然而，由于受到外围电路的布局的限制，显示面板内部分边框的窄化设计受到一定的限制。
具体来讲，例如在显示面板的显示区和驱动芯片之间存在连接像素控制电路电极和驱动芯片之间的金属走线，这些金属走线按图形大致可分为几个区域：第一扇形区：显示区域内讯号走线向外引出；第一直线区：第一扇形区走线的向下延伸，此区域为柔性弯折区，沿弯折线弯折，可将后续的第二扇形区、第二直线区、结合（Bonding）区以及柔性印刷电路板等向下弯曲，使上述至少一部分位于显示区下方，从而可以一定程度减小下部边框尺寸，其中所述显示面板的弯折状态的图示，请参阅图3所示。
如图中所示，这种结构下的所述第一扇形区110’仍然与显示区100’位于同一平面内，其还是增加了下边框的尺寸。因此，如何减小第一扇形区110’的宽度成为实现下部窄边框的难点所在。
进一步的，在传统的第一扇形区结构中，如图4所示，讯号走线由单层的第一金属层112’组成。而所述第一扇形区的宽度主要由第一金属层112’的讯号走线宽度W1及其相邻讯号线间距L1之和Pitch1决定。
而为了缩减所述第一扇形区的宽度，业界开发了一种双层金属的布线方式，具体请参阅图5所示。这种双层金属布线的方式减小了相邻两条讯号线的间距，因此，可以有效减小所述第一扇形区的有效宽度。但是另一方面，由于所述第一金属层112’和第二金属层114’之间有一层较薄的无机绝缘层（一般为SiNX）111’，因此为了避免临近的第一金属走线和第二金属走线之间的讯号串扰，不同层相邻走线之间必须保证一水平距离L3’，保证上下两层金属的任意两条走线在垂直方向上无重叠区。以此推算同层相邻讯号走线间距至少为：L1’=W2’+2L3’>L1。
具体的在一个实施方式中，其中典型值为：W1=W2=2.5μm，L1=2.1μm，L3=0.5μm，因此Pitch1’>Pitch1。从而不利于下部边框的进一步缩小。
因此，确有必要来研发一种新型的柔性显示装置，来克服现有技术中的缺陷。
 技术问题
本发明的一个方面是提供一种柔性显示装置，其能够通过缩小其第一扇形区的有效宽度，来进一步减小下部边框的宽度，从而实现超窄边框显示装置的设计。

进一步的，在不同实施方式中，其中所述第一绝缘层为设置在所述显示区内的绝缘层延伸到所述第一扇形区的部分。
进一步的，在不同实施方式中，其中所述第二绝缘层为有机材料构成的绝缘层。
进一步的，在不同实施方式中，其中所述有机材料为聚酰亚胺系列有机材料中的一种。
进一步的，在不同实施方式中，其中所述第二绝缘层的厚度为0.5~3.0μm。优选可以为1.2、1.5、1.8μm等等，具体可随需要而定，并无限定。
进一步的，在不同实施方式中，其中所述第二绝缘层为设置在所述显示区内的绝缘层延伸到所述第一扇形区的部分。
进一步的，在不同实施方式中，其中所述第一扇形区后还设置有第一直线区、第二扇形区、第二直线区和结合区，其中所述第一直线区、第二扇形区也采用上下分层设置的第一金属层和第二金属层的双层金属层布线结构，其中所述第一金属层和第二金属层之间也依次设置有第一绝缘层和第二绝缘层。

进一步的，在不同实施方式中，其中所述结合区采用第一金属层和第二金属层的双层金属层布线结构。
 有益效果
本发明涉及的一种柔性显示装置，其在双层金属层之间设置两个绝缘层，其中由于第二绝缘层的存在，使得双层金属层布线设置的第一金属层和第二金属层之间，即使两者是采用上、下正向相对重叠设置的方式，也不会使得讯号线在进行讯号传递时产生明显的寄生电容和讯号串扰现象，从而可以进一步的缩短下边框的宽度。

其中所述第二绝缘层113为有机材料构成的绝缘层，厚度为1.2~1.8μm，优选可以为1.5μm。其可以是设置在所述显示区100内的绝缘层延伸到所述第一扇形区110的部分，也可以是单独形成在所述第一扇形区110的绝缘层，具体可随需要而定，并无限定。其中涉及的所述有机材料为聚酰亚胺系列有机材料中的一种，具体材料可随需要而定，并无限定。
进一步的，其中所述第一直线区120、第二扇形区130，也采用上下分层设置的第一金属层112和第二金属层114的双层金属层布线结构，其中所述第一金属层112和第二金属层114之间依次设置有第一绝缘层111和第二绝缘层113。其中涉及的双层金属层和双层绝缘层，其涉及的结构和所选用的材料与所述第一扇形区110涉及的双层金属层和双层绝缘层一致，为避免不必要的重复，此处不再赘述。
其中所述第二直线区140可以采用第一金属层或是第二金属层的单层金属层布线结构，也可以采用如第一扇形区110所述的双层金属层布线结构，具体可随需要而定，并不限定。进一步的，其中涉及的金属层和绝缘层，其涉及的结构和所选用的材料与所述第一扇形区110的金属层和绝缘层一致，为避免不必要的重复，此处不再赘述。
进一步的，在不同实施方式中，其中所述结合区150可以是采用第一金属层或是第二金属层的单层金属层布线结构，也可以是采用双层金属层布线结构，具体可随需要而定，并无限定。其中涉及的金属层和绝缘层，其涉及的结构和所选用的材料与所述第一扇形区110的金属层和绝缘层一致，为避免不必要的重复，此处不再赘述。
本发明涉及的一种柔性显示装置，其在双层金属层之间设置两个绝缘层，其中由于第二绝缘层的存在，使得双层金属层布线设置的第一金属层和第二金属层之间，即使两者是采用上、下正向相对重叠设置的方式，也不会使得讯号线在进行讯号传递时产生明显的寄生电容和讯号串扰现象，从而可以进一步的缩短下边框的宽度。
本发明的技术范围不仅仅局限于上述说明中的内容，本领域技术人员可以在不脱离本发明技术思想的前提下，对上述实施例进行多种变形和修改，而这些变形和修改均应当属于本发明的范围内。
