Description

拼接显示装置 技术领域
本发明涉及拼接显示技术领域，尤其涉及一种拼接显示装置。
背景技术
随着大尺寸LCD(Liquid Crystal Display，即液晶显示器)/AMOLED(Active-matrix organic light emitting diode，即有源矩阵有机发光二极体)等面板的迅速发展，LCD/AMOLED显示器以其超薄、重量轻、无辐射、性能稳定等诸多优势逐渐成为显示技术的主流。目前的大尺寸LCD/AMOLED已经可以做到60寸至100寸，但仍然难满足某些特殊场合(如监控、调度等)的需求，而且超大尺寸LCD/AMOLED面板的良率难以保证。
现有的LCD/AMOLED面板由于周围电路走线布置、框胶或封装设计等的需求，显示图像周围不可避免地出现了不可显示区域，该不可显示区别称为边框，边框的存在导致在拼接时画面被分割，破坏了图像的连续性和完整性，严重影响拼接的效果。
发明内容
鉴于现有技术存在的不足，本发明提供了一种拼接显示装置，具有相对较窄的拼接缝隙，在一定程度上保证了显示画面的图像连续性和完整性。
为了实现上述的目的，本发明采用了如下的技术方案：
一种拼接显示装置，包括多个拼接设置的显示面板，每个所述显示面板包括显示区域和非显示区域，拼接显示装置包括至少一个第一显示面板和至少一个第二显示面板，所述第一显示面板的一端在其显示区域与非显示区域的交界处背向显示面弯折设置，所述第二显示面板的端部与所述第一显示面板相邻，且与所述第一显示面板弯折后的非显示区域正对并相对固定。
作为其中一种实施方式，位于所述第一显示面板和/或所述第二显示面板底部的基板为柔性基板。
作为其中一种实施方式，所述第一显示面板为有机发光显示面板，包括所述基板、设于所述基板上的有机发光层和将所述有机发光层封装于所述基板表面的封装层。
作为其中一种实施方式，所述有机发光层设于所述第一显示面板的显示区域内，所述第二显示面板的端部与所述第一显示面板的弯折后的所述封装层正对。
作为其中一种实施方式，所述第一显示面板的弯折端的所述封装层与所述基板的粘附面积大于所述第一显示面板的非弯折端。
作为其中一种实施方式，所述第二显示面板与所述第一显示面板相邻的一端在其显示区域与非显示区域的交界处也背向显示面弯折设置，且所述第一显示面板、所述第二显示面板在各自弯折后的非显示区域相互正对并相对固定。
或者，所述第二显示面板的显示区域和非显示区域共面，所述第一显示面板一端的非显示区域弯折两次后形成台阶部，所述第二显示面板搭接在所述台阶部且端部与所述台阶部的侧壁正对。
作为其中一种实施方式，所述的拼接显示装置还包括导电件，拼接设置的两个所述显示面板的所述基板的弯折端相对设置且分别设有第一绑定端，所述导电件电连接在相邻的两个所述基板的所述第一绑定端之间。
作为其中一种实施方式，所述的拼接显示装置还包括设于外围的所述显示面板的所述基板上远离拼接部位的第二绑定端，位于同一行和/或同一列的所述显示面板之间均设有所述导电件。
作为其中一种实施方式，所述第二绑定端设于拼接显示装置的两相邻边上。
本发明的拼接显示装置中至少有一个显示面板的非显示区域弯折设置而与其它显示面板拼接，拉近了相邻两个显示面板之间的显示区域的距离，可以达到缩窄甚至消除拼接显示装置中的拼接缝、改善画面分隔感的目的。

具体实施方式
需要说明的是，在本发明中，术语“上”、“下”、“内”、“外”、“竖直”、“水平”等指示的方位或位置关系为基于附图所示的方位或位置关系。这些术语主要是为了更好地描述本发明及其实施例，并非用于限定所指示的装置、结构件或组成部分必须具有特定方位，或以特定方位进行构造和操作。
并且，上述部分术语除了可以用于表示方位或位置关系以外，还可能用于表示其他含义，例如术语“上”在某些情况下也可能用于表示某种依附关系或连接关系。对于本领域普通技术人员而言，可以根据具体情况理解这些术语在本发明中的具体含义。
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
实施例1
参阅图1～图3，本实施例的拼接显示装置包括多个拼接设置的显示面板10，每个显示面板10包括显示区域A和非显示区域B，拼接后，所有的显示面板10的显示区域A共面。拼接显示装置包括至少一个第一显示面板11和至少一个第二显示面板12，第一显示面板11的一端在其显示区域A与非显示区域B的交界 处背向显示面弯折设置，第二显示面板12的端部与第一显示面板11相邻，且与第一显示面板11弯折后的非显示区域B正对并相对固定。
由于至少有一个显示面板的非显示区域弯折设置而与其它显示面板拼接，拉近了相邻两个显示面板之间的显示区域的距离，可以达到缩窄甚至消除拼接显示装置中的拼接缝、改善画面分隔感的目的。
为方便描述，本实施例中，以所有的显示面板10为OLED(有机发光显示)面板为例进行说明，可以理解的是，显示面板10也可以为其它非柔性显示面板与柔性显示面板的拼接。
如图2和图3所示，图2为图1中a-a向的剖视图，图3是第一显示面板11未弯折前的结构示意图。第一显示面板11包括基板111、设于基板111上的有机发光层112和将有机发光层112封装于基板111表面的封装层113。可以理解的是，第一显示面板11内部结构并不仅限于上述结构，例如，还具有阴极、阳极等。图2中，在弯折部位虽然显示面板11的部分有机发光层112设于拼接缝之下，此时弯折部位的有机发光层112宽度是可预设的，以使不影响拼接显示器画面显示。或者，此弯折部位有机发光层112是可以通过驱动系统预设的非显示区，此部位不会导致拼接显示器显示画面缺失或其他影响。
这里，第二显示面板12的结构与第一显示面板11完全相同，即第二显示面板12与第一显示面板11相邻的一端在其显示区域A与非显示区域B的交界处也背向显示面弯折设置，且第一显示面板11、第二显示面板12在各自弯折后的非显示区域B相互正对并相对固定。
位于第一显示面板11、第二显示面板12底部的基板111为柔性基板，使得第一显示面板11、第二显示面板12均可以根据需要进行弯折。基板111具有耐高热性和持久性，其由聚乙烯乙醚苯二甲酸、聚萘二甲酸乙二醇酯、聚碳酸酯、聚芳酯、聚醚酰亚胺、聚醚砜或聚酰亚胺的其中一种或多种制作而成。
如图3，在第一显示面板11未被弯折前，部分有机发光层112的边缘位于非显示区域B内，第一显示面板11被弯折后，与弯折后的第二显示面板12拼接，第一显示面板11的弯折部的封装层113与第二显示面板12的弯折部的封装层113正对，然后固定在一起。此时，二者构成的拼接缝宽度为第一显示面板11的有机发光层112厚度、封装层113厚度与第二显示面板12的有机发光层112厚度、封装层113厚度之和。
如图4和图5所示，与图2和图3所示的显示面板的结构不同，本实施方式中，有机发光层112设于第一显示面板11的显示区域A内，第一显示面板11、第二显示面板12弯折后拼接时，第二显示面板12弯折后的封装层113与第一显示面板11的弯折后的封装层113正对。此时，二者构成的拼接缝宽度为第一显示面板11的封装层113厚度与第二显示面板12的封装层113厚度之和。与前一种实施方式相比，该拼接缝宽度大幅降低。为防止弯折部位弯折后破坏封装层113与基板111的接触性和粘着性，第一显示面板11的弯折端的封装层113与基板111的粘附面积大于第一显示面板11的非弯折端，例如，该弯折侧的封装层113的粘附宽度或边框宽度大于其他部位。
实施例2
如图6a和图6b所示，与实施例1不同的是，本实施例的第二显示面板12的显示区域A和非显示区域B共面，第一显示面板11一端的非显示区域B弯折两次后形成台阶部，第二显示面板12搭接在台阶部且端部与台阶部的侧壁正对。与实施例1相比，本实施例仅缩窄了第一显示面板11侧的缝隙。
该实施方式可应用于柔性显示面板与非柔性显示面板的拼接过程中，第一显示面板11作为柔性显示面板，第二显示面板12作为非柔性显示面板，提高了拼接方式的多样化程度。二者构成的拼接缝宽度为第一显示面板11的有机发光层112厚度、封装层113厚度与第二显示面板12的边框宽度之和。
实施例3
如图7和图8，与实施例1不同的是，在实施例1的基础上，本实施例的第一显示面板11、第二显示面板12的基板111的弯折端长度大于边框部位的封装层113覆盖的宽度，拼接设置的第一显示面板11、第二显示面板12的基板111的弯折端相对设置后，端部分别设有第一绑定端B1，第一绑定端B1绑定有用于对应导通相应的扫描线、数据线、电源线等信号线的绑定端子，用以输入、输出和传递这些信号线的信号，导电件P电连接在相邻的两个基板111的第一绑定端B1之间，可以传递显示信号。该导电件P为异方性导电胶，只在Z轴方向上，即导电件P厚度方向上导通，避免不同的端子之间短路。
由于显示面板10之间采用异方性导电胶将信号端导通，可以减少拼接显示器电信号输入端和集成电路的数量，简化拼接显示器的线路。
如图9和图10所示，该实施例在每两个相邻的显示面板10之间均设置有 导电件P，用以连接相邻的两个显示面板10的第一绑定端B1，拼接显示装置的外围的显示面板10的基板111上远离拼接部位还设有第二绑定端B2，第二绑定端B2设于拼接显示装置的两相邻边上，上方的第二绑定端B2作为数据信号驱动端，左侧的第二绑定端B2作为扫描信号驱动端。通过将所有的屏幕的分辨率设计为相同，像素大小设计为相近或相同。水平方向上的第二绑定端B2为扫描信号驱动，水平方向上的同一行显示面板10具有相同根数的扫描线并共用扫描驱动信号，同一行显示面板10，扫描线一一对应并通过导电件P连通；竖直方向上的第二绑定端B2为数据信号驱动，竖直方向上的同一列显示面板10具有相同根数的数据线并共用数据驱动信号，且数据线一一对应并通过导电件P连通，拼接完成后，拼接显示装置可以看做一个完整的显示屏。当输入数据驱动信号和扫描驱动信号时，一帧画面内自下而上或者自上而下依次驱动，同一行显示面板10同时驱动。
如图11所示，也可以将第二绑定端B2仅设于拼接显示装置一侧，例如，设于图示的上方，集成的驱动芯片设置在拼接显示装置同一侧，可以同时控制扫描线、数据线等信号的输入与终止，可以进一步缩窄拼接显示装置的边框。
如图12所示，该拼接显示装置中，第二绑定端B2仅设于拼接显示装置一侧，且仅在竖直方向上的两显示面板10之间设置有导电件P连接两显示面板10的第一绑定端B1，此时第二绑定端B2为集成的驱动芯片，同时控制扫描线、数据线等信号的输入与终止，导致竖直方向上的同一列的显示面板10共用同一个信号输入和第二绑定端B2，而同一行的显示面板10分别使用不同的扫描驱动信号。当输入数据驱动信号和扫描驱动信号时，同一列的显示面板10显示和驱动为一个整体，不同列的显示面板10分别独立显示和驱动。
本发明的拼接显示装置中至少有一个显示面板的非显示区域弯折设置而与其它显示面板拼接，拉近了相邻两个显示面板之间的显示区域的距离，可以达到缩窄甚至消除拼接显示装置中的拼接缝、改善画面分隔感的目的。同时，显示面板之间还可通过将绑定端利用异方性导电胶电性连接，可以减少拼接显示器电信号输入端和集成电路的数量，简化拼接显示器的线路。
以上所述仅是本申请的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
