包边胶带和显示装置 技术领域
本申请涉及显示技术领域，尤其涉及一种包边胶带和显示装置。
 背景技术
现有液晶显示（Liquid Crystal Display，LCD）模组一般是将LCD液晶屏与背光模组贴合后，通过包边胶带沿着产品边缘包起来，以防止产品侧面出现漏光，同时加强LCD液晶屏与背光模组的结合。但由于包边胶带制作尺寸公差和实际贴附公差等客观因素的存在，导致液晶显示模组角落位置无法被包裹完全，会有光从外漏的胶框、以及LCD液晶屏与背光模组结合面的缝隙里透出。为此可使液晶显示模组角落位置的包边胶带重叠以减缓漏光，但包边胶带重叠过多，会在模组角落外围不规则堆积，容易和整机角落干涉，影响组装效果。
因此，现有液晶显示模组的包边胶带存在性能不佳的技术问题需要解决。

针对现有液晶显示模组的包边胶带存在性能不佳的技术问题，发明人发现主要是由于包边胶带采用分段式设计，为了减少液晶显示模组的角落处漏光，分段式的包边胶带在液晶显示模组的角落处会存在交叠，且还不能完全避免角落处漏光。
具体地，请参照图1a、图1b以及图1c，图1a至图1c为现有液晶显示模组的包边胶带贴附方式示意图。如图1a所示，相邻的两段包边胶带1-1和1-2切齐偏光片2贴附，如此在液晶显示模组900的角落处3无胶带遮挡，使得液晶显示模组900的角落处3漏光。为了减少模组角落漏光，出现了如图1b的贴附方式，相邻的两段包边胶带1-3和1-4对切液晶显示模组900的外形贴附，如此虽然能够遮挡住液晶显示模组900的角落处3，减少角落漏光，但当液晶显示模组900的角落为圆角设计时，角落处3的包边胶带会存在过多的重叠，从而影响液晶显示模组900的外形尺寸。为了改善角落漏光及胶带堆叠，出现了如图1c所示的贴附方式，相邻的两段包边胶带1-5和1-6对切液晶显示模组900的外形贴附，且相邻的两段包边胶带1-5和1-6上分别设置有突出的细条胶带1-51和1-61，其中细条胶带1-51用于包裹模组侧边，如此设计虽然能一定程度改善角落漏光及胶带堆叠，但是细条胶带1-51的宽度比模组厚度小，通常在1mm左右，实际在侧边包角贴附时，因为细条胶带1-51窄和短，容易上下歪斜，故对贴附精度要求较高，同时在模组的侧边还是存在一定的胶带堆叠。
为此，本申请实施例提供一种一体式的包边胶带和显示装置以解决上述问题。请结合参照图2至图8，图2为本申请实施例提供的包边胶带的一种展开结构示意图，图3为图2中A处的放大示意图，图4为本申请实施例提供的包边胶带的另一种展开结构示意图，图5为图4中C处的放大示意图，图6为图5中第一切口的另一种结构示意图，图7为本申请实施例提供的包边胶带的又一种展开结构示意图，图8为本申请实施例提供的包边胶带的再一种展开结构示意图。如图2至图8示出的各所述包边胶带均包括一体式设置的第一胶体部10、第二胶体部20和第三胶体部30。其中第一胶体部10、第二胶体部20和第三胶体部30沿所述包边胶带的短边方向依次排布，所述包边胶带的短边是指包边胶带边长较短的边，相应地，所述包边胶带边长较长的边即为所述包边胶带的长边。
具体地，以图2和图3示出的包边胶带100为例，所述第一胶体部10上间隔设置有第一切口11，所述第一切口的纵截面形状为矩形。所述第三胶体部30远离所述第一胶体部10的一侧间隔设置有第二切口31，所述第二切口31与所述第一切口11相对设置。所述第二胶体部20位于所述第一胶体部10和所述第三胶体部30之间。所述第一切口11的深度H1等于所述第一胶体部10的宽度，所述第二切口31的深度H2等于所述第三胶体部30的宽度。所述第一切口11的中心线B-B’与所述第二切口31的中心线B-B’重合。且在沿所述包边胶带100的长边方向上，所述第二切口31的长度大于所述第一切口11的长度。
可选地，请结合参照图4和图5所示的包边胶带101，所述第一切口11’包括第一子切口，所述第一子切口包括第一侧边111和第二侧边112，所述第一侧边111和所述第二侧边112之间形成夹角a，所述夹角a靠近所述第二切口31。且所述夹角a位于所述第一胶体部10，且所述夹角a的范围为90度至120度。
可选地，请参照图6，所述第一侧边111和所述第二侧边112之间形成夹角b，所述夹角b位于所述第二胶体部20，所述夹角b由所述第一侧边111和所述第二侧边112的延长线相交形成。

请结合参照图2至图3以及图9至图11，图9为本申请实施例提供的显示装置的一种俯视结构示意图，图10为本申请实施例提供的显示装置的一种剖面结构示意图，图11为本申请实施例提供的显示装置的细节示意图。所述显示装置1000包括显示面板200、与所述显示面板200贴合设置的背光模组300以及贴附于所述显示面板200远离所述背光模组300一侧的盖板600，所述背光模组300为所述显示面板200提供背光，所述盖板600用于保护所述显示面板200。所述显示面板200包括相对设置的阵列基板21和彩膜基板22、设置于所述阵列基板21和所述彩膜基板22之间的液晶层23、贴附于所述彩膜基板22远离所述阵列基板21一侧的上偏光片24以及贴附于所述阵列基板21远离所述彩膜基板22一侧的下偏光片25。所述上偏光片24的外轮廓241小于所述显示装置1000的外轮廓221。
所述背光模组300设置于所述阵列基板21远离所述彩膜基板22的一侧，且与所述下偏光片25之间具有间隙。可选地，所述背光模组300包括背板32、胶框33、背光源34、反射片35、导光板36、下扩散片37、增光片38、上扩散片39等。所述背板32形成有容纳腔，所述胶框33、所述背光源34以及所述反射片35等光学膜片均设置于所述容纳腔内。
可选地，所述胶框33可通过胶带粘结等固定方式固定于所述容纳腔四周，用于支撑所述显示面板200。当然地，所述胶框33还可以与所述背板32一体式设置，形成胶铁一体化背板32。所述反射片35设置于所述容纳腔底部，所述导光板36设置于所述反射片35远离所述容纳腔底部的一侧，所述背光源34设置于所述导光板36和所述胶框33之间，且所述背光源34固定于所述胶框33上，所述反射片35用于把从所述导光板36下表面出射的光线反射回所述导光板36内，以提高所述背光源34的光线利用率。其中所述导光板36的下表面是指所述导光板36面向所述反射片35的一面。
所述下扩散片37设置于所述导光板36远离所述反射片35的一侧，所述增光片38设置于所述下扩散片37远离所述导光板36的一侧，所述上扩散片39设置于所述增光片38远离所述下扩散片37的一侧。需要说明的是，本申请的背光模组300结构不限于本申请实施例示意的侧入式背光结构，本申请的背光模组300还可采用直下式背光结构，而且背光模组300的光学膜片也不限于本申请实施例示意的，本申请的背光模组300的光学膜片可根据实际需求进行具体配置。
所述背光模组300和所述显示面板200结合后，所述背光模组300和所述显示面板200结合处的缝隙以及外露的胶框33均会导致所述显示装置1000漏光。本申请的所述包边胶带100包裹于所述显示装置1000的侧面，以避免所述显示装置1000漏光，并能增强所述背光模组300与所述显示面板200的结合。可选地，所述包边胶带100的材质包括铜箔、铝箔、导电布、单面胶等。
所述包边胶带100的所述第一胶体部10上间隔设置有第一切口11，且所述第一胶体部10用于包裹所述显示装置1000的第一表面201边缘，所述显示装置1000的第一表面201边缘是指所述显示面板200远离所述背光模组300的一侧上，且未被所述上偏光片24覆盖的区域，也即所述彩膜基板22远离所述阵列基板21的一侧上未被所述上偏光片24覆盖的区域。
所述第三胶体部30上间隔设置有第二切口31，所述第二切口31与所述第一切口11相对设置，且所述第三胶体部30用于包裹所述显示装置1000的第二表面301边缘，所述显示装置1000的第二表面301边缘是指所述背光模组300远离所述显示面板200的一侧的边缘区域。
所述第二胶体部20位于所述第一胶体部10和所述第三胶体部30之间，用于包裹所述显示装置1000的侧面，所述显示装置1000的侧面是指所述显示装置1000的第一表面201与第二表面301之间形成的表面。
其中，所述第一切口11和所述第二切口31均对应于所述显示装置1000的拐角，用于使所述包边胶带100包裹所述显示装置1000后，所述显示装置1000的侧面和所述显示装置1000的第二表面301均无包边胶带100重叠，且所述显示装置1000的第一表面201边缘无漏光缝隙。所述显示装置1000的拐角是指所述显示装置1000相邻的两个侧面之间形成的夹角。当所述显示装置1000相邻的两个侧面直接相交时，所述显示装置1000的拐角为直角；当所述显示装置1000相邻的两个侧面之间设置有过渡的圆弧面时，所述显示装置1000的拐角为圆角；当所述显示装置1000相邻的两个侧面之间设置有过渡的短平面时，所述显示装置1000的拐角为斜切角。当然地，本申请的所述显示装置1000的拐角不限于此。
下面将以所述显示装置1000的拐角为直角为例，具体阐述所述第一切口11和所述第二切口31的具体结构。
具体地，所述第一切口11为破切线，所述第二切口31为V形切口。所述破切线为切割所述第一胶体部10后留下的切割道，所述切割道的纵截面形状为矩形；或者所述第一切割口也可设置为预断线，所述预断线由多个间隔的小孔形成，当需要把所述第一胶体部10贴附到所述显示装置1000的第一表面201边缘时，所述预断线断开，多个间隔的小孔贯通。所述第二切口31的V形切口是指所述第二切口31的两侧边相交形成的截面形状。
所述第一切口11的深度H1等于所述第一胶体部10的宽度，所述第二切口31的深度H2等于所述第三胶体部30的宽度。可选地，所述第一胶体部10的宽度等于所述上偏光片24的外轮廓241到所述显示装置1000的外轮廓221之间的距离，当然地，所述第一胶体部10的宽度也可以稍微小于所述上偏光片24的外轮廓241到所述显示装置1000的外轮廓221之间的距离，只要能够满足遮挡所述显示装置1000的第一表面201边缘漏光即可。其中所述第一切口11的深度H1和所述第二切口31的深度H2均是指沿平行于所述包边胶带100的短边方向延伸的长度，所述第一胶体部10和所述第三胶体部30的宽度均是指沿平行于所述包边胶带100的短边方向延伸的长度，所述包边胶带100的短边是指边长较短的边，所述包边胶带100的长边是指相较于短边边长较长的边。
所述第一切口11的中心线B-B'与所述第二切口31的中心线B-B'重合，且所述第一切口11的中心线B-B'还与所述显示装置1000的拐角的中心轴线重合，以保证所述包边胶带100在包裹所述显示装置1000时，所述包边胶带100的拐角区域位于所述第一切口11和所述第二切口31之间，且所述包边胶带100的拐角区域与所述显示装置1000的拐角区域匹配。
需要说明的是，所述第一切口11的中心线B-B'和所述第二切口31的中心线B-B'均是指平分所述第一切口11和所述第二切口31的直线，也即所述第一切口11和所述第二切口31被各自的中心线B-B'分成互相对称的两部分。所述显示装置1000的拐角的中心轴线是指所述显示装置1000相邻两个侧面相交区域的中心轴线，比如所述显示装置1000的拐角为直角时，所述显示装置1000的拐角的中心轴线即为所述显示装置1000相邻的两个侧面直接相交形成的直线。
进一步地，所述第二切口31的长度L2大于所述第一切口11的长度L1，所述第一切口11的长度L1和所述第二切口31的长度L2是指沿平行于所述包边胶带100的长边方向延伸的最长长度。
具体地，请结合参照图2至图3以及图9至图13，图12为本申请实施例提供的包边胶带贴附于显示装置第一表面的一种俯视结构示意图，图13为本申请实施例提供的包边胶带贴附于显示装置第二表面的俯视结构示意图。所述第二切口31的长度L2需满足所述第三胶体部30贴附于所述显示装置1000的第二表面301后，相邻的所述第三胶体部30之间不重叠，以避免所述显示装置1000的第二表面301由于所述第三胶体部30的堆叠而导致所述显示装置1000的厚度增加。所述第一切口11的长度L1需满足所述第一胶体部10贴附于所述显示装置1000的第一表面201后，相邻的所述第一胶体部10之间不存在缝隙，以避免所述显示装置1000的第一表面201边缘因存在缝隙而导致漏光。比如相邻的所述第一胶体部10在对应的所述显示装置1000的拐角处恰好接触或部分重叠或完全重叠，当所述显示装置1000的拐角为直角时，相邻的所述第一胶体部10在对应的所述显示装置1000的拐角处完全重叠。
而且，所述第一胶体部10贴附于所述显示装置1000的第一表面201边缘，且对应未设置所述上偏光片24的区域。所述上偏光片24的厚度大于所述包边胶带100的厚度，比如所述上偏光片24的厚度通常在0.1毫米以上，而所述包边胶带100的厚度为0.05毫米，则相邻的所述第一胶体部10在对应的所述显示装置1000的拐角处完全重叠，也不会超出所述上偏光片24的厚度，故相邻的所述第一胶体部10在对应的所述显示装置1000的拐角处完全重叠，以避免所述显示装置1000的第一表面201边缘漏光，且不会增加所述显示装置1000的整体厚度。
另外，由于所述包边胶带100是一体式设置，所述第二胶体部20贴附于所述显示装置1000的侧面后，在所述显示装置1000的侧面不存在重叠，也即在所述显示装置1000的侧面不存在所述包边胶带100堆叠，避免了与整机角落发生干涉，使外形尺寸更稳定。
在一种实施例中，请结合参照图4至图6以及图14，图14为本申请实施例提供的包边胶带贴附于显示装置第一表面的另一种俯视结构示意图。与上述实施例不同的是，在本实施例中，包边胶带101的第一切口11’包括第一子切口，所述第一子切口包括第一侧边111和第二侧边112，所述第一侧边111和所述第二侧边112之间形成夹角a，该夹角a由所述第一侧边111和所述第二侧边112直接相交形成，所述夹角a靠近所述第二切口31，例如第一切口11’为V形切口，如此所述包边胶带101贴附于所述显示装置1000后，所述显示装置1000的第一表面也不存在所述第一胶体部10的重叠，且不存在漏光间隙。
具体地，所述第一切口11’的中心线B-B'与所述第二切口31的中心线B-B'重合，则所述第一切口11’的V形切口端点与所述第二切口31的V形切口端点在同一轴线上。所述第二切口31的长度L2大于所述第一切口11的长度L1，所述第一切口11’的长度L1取决于所述显示装置1000的拐角大小，而所述第一切口11’为V形切口时，第一切口11’的长度L1也可用V形切口的开口角度表征，则所述第一切口11’的开口角度也取决于所述显示装置1000的拐角大小，且所述第一切口11’的开口角度也即所述第一切口11’的夹角a，所述夹角a的范围包括90度至120度。
需要说明的是，所述显示装置1000的拐角为直角时，所述第一切口11’可为V形切口，本申请的拐角为直角不限于拐角为90度的角，这里的拐角为直角仅用于表征所述显示装置1000相邻的侧面直接相交形成的夹角，而所述显示装置1000相邻的侧面直接相交形成的夹角包括但不限于90度的角，也可为大于90度的角或小于90度的角。当所述显示装置1000的拐角为90度的角时，所述第一切口11’的V形切口的开口角度等于或小于所述显示装置1000的拐角为直角时的角度。
另外，在一种实施例中，所述第一切口11’还可如图6所示，所述第一切口11’的所述第一侧边111和所述第二侧边112没有直接相交，所述第一侧边111和所述第二侧边112通过所述第一切口11’的底边113连接。所述第一侧边111的延长线和所述第二侧边112的延长线相交形成夹角b，所述夹角b更靠近所述第二切口31，此时所述第一切口11’的形状近似呈V型切口，该近似V型切口可实现上述V型切口的效果，同时还可适用于拐角为非直角的显示装置。其他说明请参照上述实施例，在此不再赘述。
在一种实施例中，请结合参图7和图15，图15为本申请实施例提供的显示装置的另一种俯视结构示意图。与上述实施例不同的是，所述显示装置1001的拐角为圆角，也即所述显示装置1001相邻的两个侧面之间形成有过渡圆弧面，所述圆弧面由多段圆弧D-D’组成，每段圆弧D-D’对应的角即为圆角。此时，所述第一切口11”包括第一子切口12和第二子切口13，所述第一子切口12包括第一侧边111和第二侧边112，所述第一侧边111和所述第二侧边112之间形成夹角a，所述夹角a靠近所述第二切口31，可选地，所述夹角a的范围为90度至120度，所述第一侧边111的长度等于所述第二侧边112的长度。所述第二子切口13和所述第一子切口12关于所述第一切口11”的中心线B-B’对称。
具体地，所述第一子切口12和所述第二子切口13相交设置，且所述第一子切口12和所述第二子切口13的相交部远离所述第二切口31，此时所述第一切口11”整体呈类似W形的切口。相应地，所述第二切口31为V形切口或近似V形切口。
具体地，所述第一切口11”的中心线B-B'与所述第二切口31的中心线B-B'重合，且所述第一切口11”的中心线B-B'还与所述显示装置1001的拐角的中心轴线重合，也即所述第一切口11”的中心线B-B'与圆弧面的中心轴线重合，所述圆滑面的中心轴线也即所述多段圆弧D-D’的中点组成的直线。
需要说明的是，当所述显示装置1001的拐角为圆角时，所述第一切口11”也还可以设置为V形切口或近似V型切口，例如所述显示装置1001的拐角为较小的圆角时，所述第一切口11”可设置为V形切口、近似V型切口或W形切口；当所述显示装置1001的拐角为较大的圆角时，所述第一切口11”可设置为W形切口。
当所述第一切口11”为V形切口时，所述第一切口11”的V形切口的端点与所述第二切口31的V形切口的端点在同一轴线上，且所述包边胶带102贴附于所述显示装置1001后，所述第一切口11”的V形切口的端点与所述第二切口31的V形切口的端点均与所述显示装置1001拐角处的所述圆弧D-D’的中点重合。
当所述第一切口11”为W形切口时，W形切口是由两个V形切口组合形成，两个V形切口的交叉点（也即两个V形切口相交部上的点）与所述第二切口31的V形切口的端点在同一轴线上，且所述包边胶带102贴附于所述显示装置1001后，所述第一切口11”的W形切口的两个V形切口的端点与所述显示装置1001拐角处的所述圆弧D-D’的两端端点重合。当然地，W形切口还可由两个近似V形切口组合形成或V形切口与近似V形切口组合形成。其他说明请参照上述实施例，在此不再赘述。
在一种实施例中，请结合参图8和图16，图16为本申请实施例提供的显示装置的又一种俯视结构示意图。与上述实施例不同的是，所述显示装置1002的拐角为斜切角，也即所述显示装置1002相邻的两个侧面之间形成有过渡平面，所述平面由多段直线E-E’组成，每段直线E-E’对应的角即为斜切角。此时，所述第一切口11”’包括第一子切口12和第二子切口13，所述第一子切口12包括第一侧边111和第二侧边112，所述第一侧边111和所述第二侧边112之间形成夹角a，所述夹角a靠近所述第二切口31，可选地，所述第一侧边111的长度小于所述第二侧边112的长度。所述第二子切口13和所述第一子切口12关于所述第一切口11”’的中心线B-B’对称。
具体地，所述第一子切口12和所述第二子切口13间隔设置，且所述第一子切口12和所述第二子切口13的间隔部远离所述第二切口31，此时所述第一切口11”’整体呈梯形切口。则对应地，所述第二切口31也为梯形切口，其中本申请的梯形切口和上述的近似V形切口结构相似，但梯形切口的底边长度要远大于近似V形切口的底边长度，底边长度是指连接第一侧边和第二侧边的底边的长度。
具体地，所述第一子切口12和所述第二子切口13均呈类似V形的切口，则所述第一切口11”’为梯形切口可近似看成是由两个间隔设置的V形切口组合形成，两个V形切口端点之间的直线距离等于所述显示装置1002的拐角处每段直线E-E’的距离。所述第二切口31的梯形切口可近似看成一个梯形凹槽，梯形凹槽槽底的长度等于所述显示装置1002的拐角处每段直线E-E’的距离。当所述包边胶带103贴附于所述显示装置1002后，所述第一切口11”’的梯形切口的两个V形切口端点分别于所述显示装置1002的拐角处每段直线E-E’的两端端点重合；所述第二切口31的梯形切口的槽底两端点分别于所述显示装置1002的拐角处每段直线E-E’的两端端点重合。
另外，对于所述显示装置1002的拐角为斜切角的情况，所述第一切口11”’也可以设计呈W形切口，同样能够达到梯形切口的效果。其他说明请参照上述实施例，在此不再赘述。
需要说明的是，本申请所述包边胶带上的所述第一切口的数量和所述第二切口的数量等于所述显示装置的拐角数量，而所述显示装置的拐角数量不限于本实施例示意的四个。比如所述显示装置为五边形时，所述显示装置的拐角数量为五个，则对应的所述第一切口的数量也为五个。而且所述第一切口和所述第二切口的形状也不限于本申请实施例示意的，尤其地，所述第一切口的形状可根据所述显示装置拐角处的形状进行配置，所述第一切口的形状包括但不限于本申请实施例示意的破切线、V形切口、W形切口、梯形切口或其多种组合。
在一种实施例中，请参照图17，图17为本申请实施例提供的显示装置的再一种俯视结构示意图。所述显示装置1003包括显示面板200、背光模组（图未示）和第一包边胶带400，所述背光模组与所述显示面板200相对设置，用于给所述显示面板200提供背光。所述第一包边胶带400包裹于所述显示装置1003的多个侧面，用于加固所述显示面板200和所述背光模组的结合，并避免所述显示装置1003漏光。其中所述第一包边胶带400由上述实施例其中之一的包边胶带包裹于所述显示装置1003后形成。
可选地，所述的显示装置1003还包括设置于所述显示装置1003的一侧面的电路板（图未示），以及包裹于所述电路板的第二包边胶带500。由于考虑到所述电路板结构的复杂性，则对应用于贴附所述电路板的包边胶带的材质组合也较为复杂，根据设计需要，可能要增加导电双面胶、PET、泡棉、高温胶带之类的材质，并且外形尺寸和其他三侧面的宽度和结构相差较大，故为了优化成本，在对应设置有电路板的侧面包裹第二包边胶带500，所述第一包边胶带400包裹于所述显示装置1003未设置所述电路板的侧面。也即所述显示装置1003设置有所述电路板的侧面被所述第一包边胶带400和所述第二包边胶带500一块包裹，且所述第一包边胶带400和所述第二包边胶带500部分重叠以防止所述显示装置1003局部漏光。
根据上述实施例可知：
本申请提供一种包边胶带和显示装置，包边胶带包括一体式设置的第一胶体部、第二胶体部和第三胶体部，第一胶体部间隔设置有第一切口，第三胶体部设置有与第一切口相对的第二切口，第一切口和第二切口均对应显示装置的拐角，针对不同的拐角，第一切口可设置为破切线、V形切口、W形切口、梯形切口等，如此在包边胶带包裹于显示装置后，在显示装置侧面和第一表面不留漏光缝隙，解决了模组角落漏光问题，而且在显示装置的侧面和第二表面均无包边胶带重叠和堆积，避免了与整机角落发生干涉，使外形尺寸更稳定，解决了现有液晶显示模组的包边胶带存在性能不佳的技术问题；同时包边胶带一体设计，降低了裁切和人工贴附成本。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
以上对本申请实施例进行了详细介绍，本文中应用了具体个例对本申请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申请的技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例的技术方案的范围。
