背景技术
近年来，随着显示技术的飞速发展，触控显示技术、三维显示技术、电致变色显示技术也随之迅速发展。一般地，通常需要在现有显示装置中的触控器件、三维器件、电致变色器件等外挂器件上设置柔性电路板(Flexible Printed Circuit board，FPC)，其与显示面板上的柔性电路板电性连接，从而实现外挂器件与外接信号的导通，并且最终实现显示装置的正常显示功能。
然而，在某些情况下，连接到显示装置中的外挂器件的柔性电路板所需的信号通道较少。例如参照图1，以一种裸眼三维液晶显示器为例。显示器的显示面板主要包括第一基板01、第二基板02以及夹于第一基板01和第二基板02之间的液晶层(图中未示出)。作为显示器外挂器件的液晶光栅主要包括第三基板03、第四基板04以及夹于第三基板03和第四基板04之间的液晶层(图中未示出)。另外，在显示面板和外挂器件上均设置有各自的FPC，即如图1中所示的与第一基板01电性连接的FPC1以及与第三基板03电性连接的FPC2。然而，对于这种外挂式液晶光栅，为了实现黑白显示效果，通常只需要两个电极信号通道，就可以获得明暗交替的条纹，从而实现三维显示效果。但是，如图1中所示的显示器结构，其需要额外制作连接到三维液晶光栅的FPC2，这样将会导致显示器的制作成本的提高，而且也不利于简化外挂器件的结构。
因此，在保证显示装置中外挂器件与外接信号导通的前提下，如何简化外挂器件的结构并且降低显示装置的制作成本，是本领域技术人员亟待解决的问题。

具体实施方式
下面结合附图，对本发明实施例提供的显示装置及其制作方法的具体实施方式进行详细地说明。
本发明实施例提供了一种显示装置，如图2所示，其具体可以包括：显示器件1、外挂器件2以及用于连接到外接信号的柔性电路板3；其中，
显示器件1的绑定区域中具有第一类引线和第二类引线；
外挂器件2的绑定区域中具有预留引线，预留引线与第二类引线电性连接(在图1所示的实施例中，通过导电胶D1电性连接)；并且
柔性电路板3具有第一类管脚和第二类管脚，第一类引线与第一类管脚电性连接，并且第二类引线与第二类管脚电性连接。
本发明实施例提供的上述显示装置，包括显示器件1、外挂器件2以及用于连接到外接信号的柔性电路板3；其中，显示器件1的绑定区域(虚线框A标注的区域)中具有第一类引线和第二类引线(图中未示出)；外挂器件2的绑定区域(虚线框B标注的区域)中具有预留引线(图中未示出)，预留引线与第二类引线电性连接(在图1所示的实施例中，通过导电胶D1电性连接)；并且柔性电路板3具有第一类管脚和第二类管脚，第一类引线与第一类管脚电性连接，并且第二类引线与第二类管脚电性连接。这样，外挂器件2的预留引线通过导电胶与显示器件1的第二类引线电性连接，而第二类引线又与柔性电路板3的第二类管脚电性连接，由此可以实现外挂器件2与外接信号的导通。相对于现有技术中在外挂器件与显示器件上分别设置各自的柔性电路板，本发明实施例提供的显示装置省去了单独制作外挂器件的柔性电路板的步骤，从而降低了显示装置的生产成本，同时还简化了显示装置的外挂器件的结构。
在具体实施时，本发明实施例提供的上述显示装置中，如图3a和图3b所示，在显示器件的绑定区域中，第一类引线L1和第二类引线L2可以平行排列，并且第二类引线L2位于第一类引线L1的两侧或一侧。即，可以将第二类引线L2如图3a所示设置于第一类引线L1的两侧，也可以将第二类引线L2如图3b所示设置于第一类引线L1一侧。 具体地，第一类引线L1和第二类引线L2还可以以任何其它适合的方式排列，在此不作限定。这样，通过将第一类引线L1与第二类引线L2平行排列且将第二类引线L2设置于第一类引线L1的两侧或一侧，有利于区分这两类引线，并且有利于实现导电胶的涂布。即，在第二类引线L2上涂布导电胶时，比较容易找到第二类引线L2的位置并且有利于实施导电胶的涂布。
在具体实施时，本发明实施例提供的上述显示装置中，为了防止导电胶在显示装置的后续制作工艺中的意外脱落，从而影响外挂器件与外接信号之间的导通，一般地，如图2所示，在导电胶D1上还覆盖有一层保护胶D2。这样，通过在导电胶D1上覆盖一层保护胶D2，可以防止在显示装置的制作工艺中由于直接接触导电胶D1而引起的导电胶D1的意外脱落，从而保证了外挂器件的预留引线和显示器件的第二类引线之间的电性连接，以及由此外挂器件与外接信号之间的导通。
在具体实施时，本发明实施例提供的上述显示装置中，为了实现外挂器件与外接信号之间的导通，需要将外挂器件的预留引线与显示器件的第二类引线电性连接。但是，可以存在实现这样的电性连接的多种方式，在此不作限定。在本发明实施例提供的一种实现方式中，通过导电胶涂布技术将外挂器件的预留引线与显示面板的第二类引线电性连接。然而，要指出的是，导电胶为可以实现导电胶涂布技术的金属胶中的一种，但本发明的范围并不仅限于此。优选地，导电胶可以为银胶，这是因为银胶具有良好的导电性并且有利于引线之间的信号传输。
在具体实施时，本发明实施例提供的上述显示装置中，外挂器件可以为三维器件、触控器件或电致变色器件。对于不同类型的外挂器件均可以设置预留引线。然后，通过导电胶将外挂器件上的预留引线与显示器件的第二类引线电性连接，可以实现外挂器件与外接信号的导通。相对于现有技术中在外挂器件与显示器件分别设置各自的柔性电路板，本发明实施例提供的显示装置省去了单独制作外挂器件的柔性电路板的步骤，从而降低了显示装置的生产成本，同时还简化了显示装置的外挂器件的结构。
在具体实施时，本发明实施例提供的上述显示装置可以为三维显示器，而对应的三维器件可以为液晶光栅(LC barrier)、电致变色光 栅或液晶透镜(LC lens)。本发明实施例提供的上述显示装置也可以应用于手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等具有显示功能的任何产品或部件中，即，可以根据实际需要应用于各类显示产品中，在此不作限定。
在具体实施时，本发明实施例提供的上述显示装置中，外挂器件包括透明电极，该透明电极可以为插指结构或叠层结构。具体地，下面以外挂器件是电致变色光栅为例进行说明。如图4a所示，电致变色光栅包括形成插指结构的两个透明梳状电极201和202，以及填充于两个梳状电极的间隙中的电致变色材料203。具体地，两个分立的梳状电极的两端P1和P2可以用作外挂器件的预留引线端。通过导电胶将该预留引线端与显示器件的第二类引线电性连接，可以实现外挂器件与外接信号的导通。通过对两个分立的梳状电极的两端P1和P2施加正负电压信号，在梳状电极之间形成电场，从而使填充于两个梳状电极的间隙中的电致变色材料可以在电场的作用下发生颜色变化，由此实现不同的颜色显示并且最终实现电致变色光栅的正常显示功能。
具体地，电致变色光栅也可以是如图4b所示的叠层结构，其中电致变色光栅包括第一透明电极204和第二透明电极205，以及填充于两个透明电极间的电致变色材料203。两个分立的透明电极的两端P3和P4可以用作外挂器件的预留引线端。通过导电胶将该预留引线端与显示器件的第二类引线电性连接，可以实现外挂器件与外接信号的导通。通过对两个分立的透明电极的两端P3和P4施加正负电压信号，在两个透明电极之间形成电场，从而使填充于两个透明电极间的电致变色材料可以在电场的作用下发生颜色变化，由此实现不同的颜色显示并且最终实现电致变色光栅的正常显示功能。另外，与插指结构的透明电极不同，在叠层结构的透明电极中，为了实现第一透明电极204的预留引线端P3和第一透明电极204的导通，需要在两个透明电极间的电致变色材料203上形成过孔206。在图4c中示出沿图4b所示的AB切割方向的叠层结构的透明电极层的截面图。
本发明实施例提供了一种上述显示装置的制作方法，如图5所示，具体可以包括以下步骤：
S101、在显示器件的绑定区域中形成第一类引线和第二类引线；
S102、在外挂器件的绑定区域中形成预留引线；
S103、将外挂器件的预留引线与显示器件的第二类引线电性连接；以及
S104、将显示器件的第一类引线与柔性电路板的第一类管脚电性连接，并且将显示器件的第二类引线与柔性电路板的第二类管脚电性连接。
在具体实施时，本发明实施例提供的上述显示装置的制作方法中，可以通过导电胶实现外挂器件的预留引线与显示器件的第二类引线的电性连接。
本发明实施例提供的上述显示装置的制作方法中，在显示器件的绑定区域中设置第一类引线和第二类引线；在外挂器件的绑定区域中设置预留引线；将外挂器件的预留引线与显示器件的第二类引线电性连接(在具体实施例时，可以采用导电胶实现该电性连接)；以及将显示器件的第一类引线与柔性电路板的第一类管脚电性连接，并且将显示器件的第二类引线与柔性电路板的第二类管脚电性连接。这样，外挂器件的预留引线通过导电胶与显示器件的第二类引线电性连接，而第二类引线又与柔性电路板的第二类管脚电性连接，由此可以实现外挂器件与外接信号的导通。相对于现有技术中在外挂器件与显示器件上分别设置各自的柔性电路板，本发明实施例提供的显示装置省去了单独制作外挂器件的柔性电路板的步骤，从而降低了显示装置的生产成本，同时还简化了显示装置的外挂器件的结构。
在具体实施时，本发明实施例提供的上述显示装置的制作方法中，为了防止导电胶在显示装置的后续制作工艺中的意外脱落，从而影响外挂器件与外接信号的导通，还可以包括以下步骤：在采用导电胶将外挂器件的预留引线与显示器件的第二类引线电性连接之后，在导电胶上涂布一层保护胶。这样，通过在导电胶上覆盖一层保护胶，可以防止在显示装置的制作工艺中由于直接接触导电胶而引起的导电胶的意外脱落，从而保证了外挂器件的预留引线和显示器件的第二类引线之间的电性连接，以及由此外挂器件与外接信号之间的导通。
本发明实施例提供了一种显示装置及其制作方法。该显示装置包括显示器件、外挂器件以及用于连接到外接信号的柔性电路板；其中，显示器件的绑定区域中具有第一类引线和第二类引线；外挂器件的绑定区域中具有预留引线，预留引线与第二类引线电性连接；并且柔性 电路板具有第一类管脚和第二类管脚，第一类引线与第一类管脚电性连接，并且第二类引线与第二类管脚电性连接。这样，外挂器件的预留引线与显示器件的第二类引线电性连接，而第二类引线又与柔性电路板的第二类管脚电性连接，由此可以实现外挂器件与外接信号的导通。相对于现有技术中在外挂器件与显示器件上分别设置各自的柔性电路板，本发明实施例提供的显示装置省去了单独制作外挂器件的柔性电路板的步骤，从而降低了显示装置的生产成本，同时还简化了显示装置的外挂器件的结构。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
