Description

一种拼接显示装置 技术领域
本申请涉及显示设备技术领域，尤其涉及一种拼接显示装置。
 背景技术
Micro LED（Micro Light Emitting Diode，微型发光二极管）显示技术相比现有的其他显示技术具有高亮度，高对比度，宽色域，大视角，低功耗，长寿命，超薄柔性显示等优点，是未来显示的终极技术。此外，各个显示应用场景对于大尺寸显示的需求也愈来愈烈，受限于玻璃基板原始尺寸及薄膜晶体管制造设备对基板流片尺寸的限制，目前大于110寸以上的显示器只能通过小尺寸显示单元拼接来实现。
 技术问题
LCD（Liquid Crystal Display，液晶显示器）因为需要框胶对液晶层的保护，拼接的过程中不可避免会有黑色拼接缝，同样Micro LED显示拼接也会存在拼接缝的问题，大屏拼接显示中，因拼接缝的存在产生不连续的问题，影响用户体验；因此，因拼接缝的存在产生不连续的问题亟待解决。
 技术解决方案
鉴于上述现有技术的不足，本申请的目的在于提供一种拼接显示装置，旨在解决现有拼接显示装置的拼接缝不连续影响用户体验的技术问题。
本申请提供了一种拼接显示装置，至少包括两个互相拼接的单元显示面板，各个所述单元显示面板包括第一拼接区、与所述第一拼接区连接的显示区以及与所述显示区连接的第二拼接区；在所述拼接显示装置的第一方向上，任意相邻的两个所述单元显示面板包括第一单元显示面板和第二单元显示面板；所述第一单元显示面板的第二拼接区与所述第二单元显示面板的第一拼接区连接。
在上述技术方案中，本申请的拼接显示装置由至少两个单元显示面板互相拼接组成，由于每个单元显示面板都包括有第一拼接区、显示区和第二拼接区，这样任意相邻的第一单元显示面板和第二单元显示面板拼接时，只需要将第一单元显示面板的第二拼接区与第二单元显示面板的第一拼接区连接就可以完成两个单元显示面板间的拼接，整个拼接的过程简单，且拼接后的单元显示面板结构紧凑，具有更好的显示效果。
可选地，各个用于拼接的所述单元显示面板包括第一基板和第二基板：所述第一基板包括第一拼接区与像素区；所述第二基板包括第二拼接区、以及与所述第二拼接区连接的走线区；其中，所述第一基板与所述第二基板相对设置，所述第二基板的走线区朝向所述第一基板的像素区，以形成显示区。
在上述技术方案中，各个单元显示面板由第一基板和第二基板相对设置形成，且第一拼接区和第二拼接区分别设置在第一基板和第二基板上，这种单元显示面板结构，第一单元显示面板的第二拼接区连接第一单元显示面板的第二拼接区时更加方便。
可选地，所述走线区至少包括部分透明走线。
在上述技术方案中，由于第二基板的走线区至少包括部分透明走线，这样走线区可以具有更好的透光效果，像素区发出的光线能够更好的穿过走线区，单元显示面板也就具有更好的显示效果。
可选地，各个用于拼接的所述单元显示面板包括第一基板和第二基板：所述第一基板包括第一拼接区域与像素区；所述第二基板包括第二拼接区、以及与所述第二拼接区连接的透光区；其中，所述第一基板与所述第二基板相对设置，所述第二基板的透光区朝向所述第一基板的像素区，以形成显示区。
在上述技术方案中，由于第一基板上的像素区对应第二基板上的区域为透光区，相较于第一基板上的像素区对应第二基板上的区域为走线区的实施方式而言，像素区发出的光线不会被走线遮挡，这样单元显示面板的显示的图像可以更加完整，显示效果更好。
可选地，一所述单元显示面板的所述第一拼接区呈“一”字形，所述第二拼接区远离所述第一拼接区设置且呈“一”字形。
在上述技术方案中，各个单元显示面板的两侧便可以用于拼接。
可选地，一所述单元显示面板的所述第一拼接区呈“L”字形，所述第二拼接区呈与所述第一拼接区对应的倒“L”字形。
在上述技术方案中，各个单元显示面板的四周均可以用于拼接。
可选地，所述第一基板的第一拼接区包括第一接线端子；所述像素区包括设置在所述第一基板的一侧的驱动阵列、设置在所述驱动阵列之上且与所述驱动阵列连接的发光单元；所述第一接线端子与所述驱动阵列连接；所述第二拼接区包括第二接线端子。
可选地，所述第一单元显示面板的第二拼接区的第二接线端子与所述第二单元显示面板的第一拼接区的第一接线端子连接。
在上述技术方案中，第一拼接区包括第一接线端子，第二拼接区包括第二接线端子，这样第二单元显示面板的第一拼接区和第一单元显示面板的第二拼接区拼接后，可以直接通过第一接线端子和第二接线端子实现线路导通，相邻两个单元显示面板之间的线路导通可以更加方便。
可选地，所述第一单元显示面板的第二拼接区的第二接线端子与所述第二单元显示面板的第一拼接区的第一接线端子通过导电胶连接；或者，所述第一单元显示面板的第二拼接区的第二接线端子与所述第二单元显示面板的第一拼接区的第一接线端子通过金属键合连接。
在上述技术方案中，第一单元显示面板的第二拼接区的第二接线端子与第二单元显示面板的第一拼接区的第一接线端子之间通过导电胶或金属键合来连接，导电胶或金属键合具有很好的电连接性能，且通过导电胶或金属键合进行电连接，过程无需用到走线，简化了连接步骤，操作简单。
可选地，所述的拼接显示装置还包括：驱动控制模块；所述驱动控制模块与至少一个所述单元显示面板的第一拼接区连接。
 有益效果
在本申请的技术方案中，由于单元显示面板之间是连通的，所以驱动控制模块只需要与至少一个所述单元显示面板的第一拼接区连接就可以完成整个整个拼接显示装置的发光控制，无需每一个单元显示面板通过单独的走线设计分别与一个驱动控制模块连接，减少了各个单元显示面板的边缘区域的走线占用空间，实现了拼接处画面连续的效果，且多个单元显示面板与一个驱动控制模块连接，减少了驱动控制模块的使用数量，节约了成本。

下面结合附图和实施例对本申请作进一步说明。
参见图1，本申请提供了一种拼接显示装置，至少包括两个互相拼接的单元显示面板10，参见图2，各个所述单元显示面板10包括第一拼接区20、与所述第一拼接区20连接的显示区30以及与所述显示区30连接的第二拼接区40。
参见图3，在所述拼接显示装置的第一方向上，任意相邻的两个所述单元显示面板包括第一单元显示面板50和第二单元显示面板60；所述第一单元显示面板50的第二拼接区40与所述第二单元显示面板60的第一拼接区20连接。
本申请的拼接显示装置由至少两个单元显示面板10互相拼接组成，由于每个单元显示面板10均包括有第一拼接区20、显示区30和第二拼接区40，这样任意相邻的第一单元显示面板50和第二单元显示面板60拼接时，只需要直接将第一单元显示面板50的第二拼接区40与第二单元显示面板60的第一拼接区20连接就可以完成两个单元显示面板10间的拼接，整个拼接的过程简单，且拼接后的单元显示面板10结构紧凑，具有更好的显示效果，实现了画面的连续显示。需要说明的是，本申请的拼接显示装置可以应用在Mini-LED拼接显示、OLED拼接显示或Micro-LED拼接显示技术中，具体应用在此不做限定。
参见图4，各个用于拼接的所述单元显示面板10包括第一基板70和第二基板120：在一些实施方式中，参见图5，所述第一基板70包括第一拼接区20与像素区80；所述第一基板70的第一拼接区20包括第一接线端子90；所述像素区80远离所述第一拼接区20的一侧设置有第一内部接线端子100。
所述像素区80包括设置在所述第一基板70的一侧的驱动阵列、设置在所述驱动阵列之上且与所述驱动阵列连接的发光单元110；所述第一接线端子90和所述第一内部接线端子100均与所述驱动阵列连接。
参见图6，所述第二基板120包括第二拼接区40、以及与所述第二拼接区40连接的透光区130；所述第二拼接区40包括第二接线端子140；所述透光区130靠近所述第二拼接区40的一侧设置有第二内部接线端子150，所述第二内部接线端子150与所述第二接线端子140走线连接，由于所述第二内部接线端子150靠近所述第二接线端子140，所以第二内部接线端子150与第二接线端子140之间的走线不用经过透光区130。
参见图2，所述第一基板70与所述第二基板120相对设置，所述第二基板120的透光区130朝向所述第一基板70的像素区80，以形成显示区30。所述第二内部接线端子150用于与所述第一内部接线端子100相连，以使所述第二接线端子140建立与所述驱动阵列的电连接，所述第一接线端子90和所述第二接线端子140主要用于所述发光单元110的信号传输，多个上述单元显示面板10拼接后的状态如图7所示。
参见图4，各个用于拼接的所述单元显示面板包括第一基板70和第二基板120：在另一些实施方式中，参见图8，所述第一基板70包括第一拼接区20与像素区80；所述第一基板70的第一拼接区20包括第一接线端子90；所述像素区80靠近所述第一拼接区20的一侧设置有第一内部接线端子100；所述像素区80包括设置在所述第一基板70的一侧的驱动阵列、设置在所述驱动阵列之上且与所述驱动阵列连接的发光单元110；所述第一接线端子90和所述第一内部接线端子100均与所述驱动阵列连接。
所述像素区80包括设置在所述第一基板70的一侧的驱动阵列、设置在所述驱动阵列之上且与所述驱动阵列连接的发光单元110；所述第一接线端子90和所述第一内部接线端子100与所述驱动阵列连接；所述驱动阵列与所述第一接线端子90和所述第一内部接线端子100之间的连接线包括数据信号线，电源线和扫描信号线等，为改善视效及保护发光元件不从驱动轴阵列上掉落，发光元件上面设置有封胶层或其他光学膜贴附。
参见图9，所述第二基板120包括第二拼接区40、以及与所述第二拼接区40连接的走线区160；所述第二拼接区40包括第二接线端子140；所述走线区160远离所述第二拼接区40的一侧设置有第二内部接线端子150，所述第二内部接线端子150与所述第二接线端子140走线连接，所述第二内部接线端子150与所述第二接线端子140之间的走线经过所述走线区160。
参见图10，所述第一基板70与所述第二基板120相对设置，所述第二基板120的走线区160朝向所述第一基板70的像素区80，以形成显示区30，所述第二内部接线端子150用于与所述第一内部接线端子100相连，以使所述第二接线端子140建立与所述驱动阵列的电连接，所述第一接线端子90和所述第二接线端子140主要用于所述发光单元110的信号传输，多个上述单元显示面板10拼接后的状态如图11所示。
参见图8，在某些实施方式中，所述走线区160至少包括部分透明走线170。由于第二基板120的走线区160至少包括部分透明走线170，即在第二基板120上，部分第二接线端子140和部分第二内部接线端子150之间采用透明走线170相连，部分第二接线端子140和部分第二内部接线端子150之间采用金属走线180相连，这样走线区160也能够具有很好的透光效果，像素区80发出的光线能够更好的穿过走线区160，技术方案的实施成本低。
在某些实施方式中，所述透明走线170包括氧化铟锡（ITO）透明走线170。氧化铟锡具有很好的导电性和透明性，用于第二接线端子140和第二内部接线端子150之间连接，能够起到很好的电连接的效果，且几乎不会影响显示。
参见图12，在某些实施方式中，一所述单元显示面板的所述第一拼接区20呈“一”字形，所述第二拼接区40远离所述第一拼接区20设置且呈“一”字形。各个单元显示面板10的两侧便可以用于拼接。
参见图4，在某些实施方式中，一所述单元显示面板10的所述第一拼接区20呈“L”字形，所述第二拼接区40呈与所述第一拼接区20对应的倒“L”字形。各个单元显示面板10的四周均可以用于拼接。
在某些实施方式中，本申请的单元显示面板10的整体结构可以理解成是在第一基板70上层叠第二基板120，且第一基板70和第二基板120至少在一个方向上是错位设置的，这样就能够在第一基板70的表面的边缘形成第一拼接区20以及在第二基板120的底面的边缘形成第二拼接区40，当第一基板70和第二基板120只在一个方向上错位时，第一拼接区20和第二拼接区40呈“一”字形，当第一基板70和第二基板120在两个相互垂直的方向上均错位时，此时，第一拼接区20和第二拼接区40呈“L”字形。
在某些实施方式中，所述第一单元显示面板50和所述第二单元显示面板60拼接时，所述第一单元显示面板50的第二拼接区40的第二接线端子140与所述第二单元显示面板60的第一拼接区20的第一接线端子90连接。第一拼接区20包括第一接线端子90，第二拼接区40包括第二接线端子140，这样第二单元显示面板60的第一拼接区20和第一单元显示面板50的第二拼接区40拼接后，可以直接通过第一接线端子90和第二接线端子140实现线路导通，相邻两个单元显示面板10之间的线路导通可以更加方便。
在某些实施方式中，所述第一单元显示面板50的第二拼接区40的第二接线端子140与所述第二单元显示面板60的第一拼接区20的第一接线端子90通过导电胶连接；或者，所述第一单元显示面板50的第二拼接区40的第二接线端子140与所述第二单元显示面板60的第一拼接区20的第一接线端子90通过金属键合连接。
第一单元显示面板50的第二拼接区40的第二接线端子140与第二单元显示面板60的第一拼接区20的第一接线端子90之间通过导电胶或金属键合来连接，导电胶或金属键合具有很好的电连接性能，且通过导电胶或金属键合进行电连接，过程无需用到走线，简化了连接步骤，操作简单。
在某些实施方式中，所述导电胶包括ACF（Adhesive Conductive Film，异向导电膜）胶，ACF胶的粘接性和导电性能好，且固化速率快；所述金属键合包括具有凸点下金属化层的金属共晶键合，比如铜（Cu）-锡（Sn），铟（In）-金（Au）等共晶架构的金属键合，导电胶和金属键合具体可以根据实际需要进行选择，本技术方案在此不做限定。
在某些实施方式中，所述的拼接显示装置还包括：驱动控制模块；所述驱动控制模块与至少一个所述单元显示面板10的第一拼接区20连接。
由于单元显示面板10之间是连通的，所以驱动控制模块只需要与至少一个所述单元显示面板10的第一拼接区20连接就可以完成整个整个拼接显示装置的发光控制。
在某些实施方式中，所述驱动控制模块包括电路板以及设置在所述电路板上的驱动IC芯片，所述驱动IC芯片的型号包括DM13C，DM13C 是可以应用在发光二极管(light emitting diode,LED)显示所设计的恒流驱动芯片,并且具有过温断电的功能，可以避免芯片在高温环境使用下而毁损。
综上所述，本申请提供了一种拼接显示装置，至少包括两个互相拼接的单元显示面板，各个单元显示面板包括第一拼接区、与第一拼接区连接的显示区以及与显示区连接的第二拼接区；在拼接显示装置的第一方向上，任意相邻的两个单元显示面板包括第一单元显示面板和第二单元显示面板；第一单元显示面板的第二拼接区与第二单元显示面板的第一拼接区连接。本申请的拼接显示装置由于各个单元显示面板都包括第一拼接区、显示区和第二拼接区，这样任意相邻的两个单元显示面板拼接时，只需将一个单元显示面板的第二拼接区与另一个单元显示面板的第一拼接区连接就可以完成拼接，拼接的过程简单，且得到的拼接显示装置结构紧凑，具有更好的显示效果。
此外，由于单元显示面板之间是连通的，所以驱动控制模块只需要与至少一个所述单元显示面板的第一拼接区连接就可以完成整个整个拼接显示装置的发光控制，无需每一个单元显示面板通过单独的走线设计分别与一个驱动控制模块连接，减少了各个单元显示面板的边缘区域的走线占用空间，实现了拼接处画面连续的效果，且多个单元显示面板与一个驱动控制模块连接，减少了驱动控制模块的使用数量，节约了成本。
应当理解的是，本申请的应用不限于上述的举例，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，所有这些改进和变换都应属于本申请所附权利要求的保护范围。
