本申请提供一种拼接面板100，以下进行详细说明。需要说明的是，以下实施例的描述顺序不作为对本申请实施例优选顺序的限定。
请参阅图1，图1是本申请提供的拼接面板100的第一结构示意图，图2是图1中A-A剖视图。本申请提供一种拼接面板100，其包括至少两个显示面板10、发光二极管灯板20和调光层30。
其中，至少两个所述显示面板10拼接设置，两个相邻的所述显示面板10之间具有缝隙11；所述发光二极管灯板20设置在两个相邻的所述显示面板10之间且遮挡所述缝隙11；所述调光层30设在所述发光二极管灯板20上，所述调光层30上设有多个第一遮光部40，多个所述第一遮光部40呈阵列排布，所述第一遮光部40的长度方向沿第一方向X设置。
LCD拼接面板100为了解决拼缝的视觉问题，通常在LCD拼接面板100的拼缝处设有发光二极管灯板20，虽然发光二极管灯板20可以改善LCD拼接面板100的拼缝视觉问题，但是发光二极管灯板20和液晶显示面板10之间还存在视觉差异。而本申请通过在所述发光二极管灯板20上设有调光层30，而调光层30位于所述发光二极管灯板20的出光方向上，然后调光层30设有呈阵列排布的多个所述第一遮光部40，而且所述第一遮光部40的长度方向沿第一方向X设置，由于所述第一遮光部40在所述发光二极管灯板20的出光方向存在一定的高度；另外，也可以根据实际需要调节所述第一遮光部40在所述阵列的列向和行向的间距，从而调节所述第一遮光部40的密集度。由于发光二极管灯板20在侧边的亮度视角大，通过增加第一遮光部40可以减弱发光二极管灯板20在第一方向X的两侧的出光，同时调整第一遮光部40在所述发光二极管灯板20的出光方向的高度以及第一遮光部40的分布密度，则可以使所述发光二极管灯板20和显示面板10在侧向的视角一致，从而改善拼接面板100的显示面板10与发光二极管灯板20之间在第一方向X的两侧的视觉差异。
在一些实施例中，所述发光二极管灯板20为次毫米级发光二极管灯板20或微型发光二极管灯板20。
对于显示面板10为LCD显示面板10时，由于LCD显示面板10的像素间距较小，所述发光二极管灯板20优先为次毫米级发光二极管灯板或微型发光二极管灯板，这样可以与LCD显示面板10的像素间距相匹配。
具体地，所述发光二极管灯板20包括：
基板21，所述基板21设置在两个相邻的所述显示面板10上且遮挡所述缝隙11；
发光二极管芯片22，所述发光二极管芯片22设在所述基板21的一侧。
所述发光二极管芯片22为次毫米级发光二极管芯片或微型发光二极管芯片。第一遮光部40与发光二极管芯片22可以相错开设置，也可以不错开设置，也即是第一遮光部40在基板21的正投影与发光二极管芯片22在基板21的正投影可以重叠也可以不重叠，第一遮光部40具体布置方式可以根据实际情况设置。
在一些实施例中，所述调光层30包括：
封胶层31，所述封胶层31覆盖在所述发光二极管灯板20上，所述封胶层31远离所述发光二极管灯板20的侧面设有多个所述第一遮光部40。具体地，所述封胶层31覆盖在所述基板21设有所述发光二极管芯片22的一侧上。
封胶层31可以将所述发光二极管芯片22封装固定在基板21上，同时也设有第一遮光部40，这样可以减少结构设置，降低成本。
进一步地，所述封胶层31远离所述发光二极管灯板20的侧面设有向所述发光二极管灯板20的出光方向凸出的多个所述第一遮光部40。多个所述第一遮光部40呈阵列排布，所述第一遮光部40的长度方向沿第一方向X设置。
所述第一遮光部40由遮光材料制成，优选为黑色遮光材料，所述第一遮光部40的形状可以为方形体，在一个实施例中，基板21的长度为250毫米、宽度为70毫米，相邻所述第一遮光部40的行间间距为64微米，相邻所述第一遮光部40的列间间距为70微米，方形体的长度为126微米、宽度为20微米、高度为100微米。
请参阅图3，图3是本申请提供的拼接面板100的第二结构示意图，本实施例与图2提供的拼接面板100不同的是，所述第一遮光部40包括：
第一凹槽311，所述封胶层31远离所述发光二极管灯板20的侧面设有所 述第一凹槽311，所述第一凹槽311内填充有遮光材料。
也即是，在上述实施例中，通过在所述封胶层31远离所述发光二极管灯板20的侧面设有所述第一凹槽311，并在第一凹槽311内填充有遮光材料，从而形成第一遮光部40，而且第一遮光部40位于所述封胶层31内，可以避免第一遮光部40被外力触碰而损坏。
请参考图4，图4是本申请提供的拼接面板100的第二结构的制造过程示意图。首先形成发光二极管灯板20；其中所述发光二极管灯板20包括基板21发光二极管芯片22，所述基板21设置在两个相邻的所述显示面板10上且遮挡所述缝隙11，所述发光二极管芯片22设在所述基板21的一侧。接着在所述发光二极管灯板20基础上形成封胶层31，接着在所述封胶层31远离所述发光二极管灯板20的一侧开设第一凹槽311，然后在第一凹槽311内填充遮光材料，从而形成第一遮光部40，最后将所述发光二极管灯板20、封胶层31以及第一遮光部40安装在相邻的显示面板10之间。
请参阅图5，图5是本申请提供的拼接面板100的第三结构示意图，图6是图5中A-A剖视图。本实施例与图2提供的拼接面板100不同的是，所述调光层30包括：
封胶层31，所述封胶层31覆盖在所述发光二极管灯板20上；
透明保护层32，所述透明保护层32设在所述封胶层31远离所述发光二极管灯板20的一侧，所述透明保护层32上设有多个所述第一遮光部40。
也即是，在本实施例中，将第一遮光部40设在透明保护层32上，可以增大第一遮光部40与发光二极管灯板20的间距，在为了获得相同视角的条件下，相对于将第一遮光部40设在封胶层31上的实施方式，将第一遮光部40设在透明保护层32上的实施方式可以使得第一遮光部40的高度较低，第一遮光部40的高度具有更多的选择，因此本实施例可以具有更多视角效果选择。
另外，所述透明保护层32为透明玻璃或者涤纶树脂层。
在一些实施例中，所述透明保护层32远离所述发光二极管灯板20的侧面设有向所述发光二极管灯板20的出光方向凸出的多个所述第一遮光部40。将所述第一遮光部40凸出设置在所述透明保护层32远离所述发光二极管灯板20的侧面的结构可以使得制造过程简单，有利于提高生产效率。
请参阅图7，图7是本申请提供的拼接面板100的第四结构示意图，本实施例与图6提供的拼接面板100不同的是，所述第一遮光部40包括：
第一凹槽321，所述透明保护层32靠近或远离所述发光二极管灯板20的侧面设有所述第一凹槽321，所述第一凹槽321内填充有遮光材料。
也即是，在上述实施例中，通过在所述透明保护层32靠近或远离所述发光二极管灯板20的侧面设有所述第一凹槽321，并在第一凹槽321内填充有遮光材料，从而形成第一遮光部40，而且第一遮光部40位于所述透明保护层32内，可以避免第一遮光部40被外力触碰而损坏。具体地，在本实施例中，所述透明保护层32靠近所述发光二极管灯板20的侧面设有所述第一凹槽321。可以根据所述第一遮光部40与所述发光二极管灯板20的距离的实际需要，设置所述第一凹槽321在所述透明保护层32的位置。
请参阅图8，图8是本申请提供的拼接面板100的第五结构示意图，图9是图8中A-A剖视图。本实施例与图1提供的拼接面板100不同的是，所述调光层30上设有多个第二遮光部50，多个所述第二遮光部50呈阵列排布，所述第二遮光部50的长度方向沿第二方向Y设置。
而本申请通过在调光层30设有呈阵列排布的多个所述第二遮光部50，而且所述第二遮光部50的长度方向沿第二方向Y设置，由于所述第二遮光部50在所述发光二极管灯板20的出光方向存在一定的高度；另外，也可以根据实际需要调节所述第二遮光部50在所述阵列的列向和行向的间距，从而调节所述第二遮光部50的密集度。由于发光二极管灯板20在侧边的亮度视角大，通过增加第二遮光部50可以减弱发光二极管灯板20在第二方向Y的两侧的出光，同时调整第二遮光部50在所述发光二极管灯板20的出光方向的高度以及第二遮光部50的分布密度，则可以使所述发光二极管灯板20和显示面板10在侧向的视角一致，从而改善拼接面板100的显示面板10与发光二极管灯板20之间在第一方向X的两侧的视觉差异。
也即是，在改善显示面板10与发光二极管灯板20之间在第一方向X的两侧的视觉差异，再改善显示面板10与发光二极管灯板20之间在第二方向Y的两侧的视觉差异，从而实现改善显示面板10与发光二极管灯板20之间在四个侧向的视觉差异，进一步提高拼接面板100的视觉效果。
在一些实施例中，所述第一方向X与所述第二方向Y相垂直。当然所述第一方向X也可以与平行四边形的第一边相平行，而所述第二方向Y与平行四边形的第二边相平行，第一边与第二边相邻。
进一步地，所述第一遮光部40在所述第一方向X的正投影和与所述第一遮光部40相邻的所述第二遮光部50在所述第一方向X的正投影之间具有第一间隙61。由于在第一方向X设有第一遮光部40，在第二方向Y设有第二遮光部50，相邻的第一遮光部40和第二遮光部50之间在相靠近的一端如果形成闭合结构则会导致在某个侧向的视觉存在黑点，因此将第一遮光部40在所述第一方向X的正投影和与所述第一遮光部40相邻的所述第二遮光部50在所述第一方向X的正投影之间设有第一间隙61，可以避免产生视觉黑点。
进一步地，所述第一遮光部40在所述第二方向Y的正投影和与所述第一遮光部40相邻的所述第二遮光部50在所述第二方向Y的正投影之间具有第二间隙62。由于在第一方向X设有第一遮光部40，在第二方向Y设有第二遮光部50，相邻的第一遮光部40和第二遮光部50之间在相靠近的一端如果形成闭合结构则会导致在某个侧向的视觉存在黑点，因此将第一遮光部40在所述第二方向Y的正投影和与所述第一遮光部40相邻的所述第二遮光部50在所述第二方向Y的正投影之间设有第二间隙62，可以避免产生视觉黑点。
其中，第二遮光部50与发光二极管芯片22可以相错开设置，也可以不错开设置，也即是第二遮光部50在基板21的正投影与发光二极管芯片22在基板21的正投影可以重叠也可以不重叠，第二遮光部50具体的设置方式可以根据实际需要设置。
在一些实施例中，所述调光层30包括：
封胶层31，所述封胶层31覆盖在所述发光二极管灯板20上，所述封胶层31远离所述发光二极管灯板20的侧面设有多个所述第一遮光部40和多个所述第二遮光部50。具体地，所述封胶层31覆盖在所述基板21设有所述发光二极管芯片22的一侧上。
封胶层31可以将所述发光二极管芯片22封装固定在基板21上，同时也设有第一遮光部40和第二遮光部50，这样可以减少结构设置，降低成本。
进一步地，所述封胶层31远离所述发光二极管灯板20的侧面设有向所述 发光二极管灯板20的出光方向凸出的多个所述第一遮光部40。多个所述第一遮光部40呈阵列排布，所述第一遮光部40的长度方向沿第一方向X设置。将所述第一遮光部40凸出设置在所述封胶层31远离所述发光二极管灯板20的侧面的结构可以使得制造过程简单，有利于提高生产效率。
进一步地，所述封胶层31远离所述发光二极管灯板20的侧面设有向所述发光二极管灯板20的出光方向凸出的多个所述第二遮光部50。多个所述第二遮光部50呈阵列排布，所述第二遮光部50的长度方向沿第二方向Y设置。将所述第二遮光部50凸出设置在所述封胶层31远离所述发光二极管灯板20的侧面的结构可以使得制造过程简单，有利于提高生产效率。
所述第一遮光部40和所述第二遮光部50由遮光材料制成，优选为黑色遮光材料，所述第一遮光部40和所述第二遮光部50的形状可以为方形体，相邻所述第一遮光部40的列间间距范围为74微米至140微米，相邻所述第一遮光部40的行间间距为30微米至50微米，相邻所述第二遮光部50的行间间距为74微米至140微米，相邻所述第二遮光部50的列间间距为30微米至50微米，所述第一遮光部40和所述第二遮光部50的长度范围为54微米至90微米、宽度范围为10微米至20微米、高度范围为100微米至167微米。经过本申请人实验研究可得，所述第一遮光部40和所述第二遮光部50的阵列结构采用上述的规格模式具有较好的视觉效果，而且不会产生视觉黑点或黑条。
在一个实施例中，相邻所述第一遮光部40的行间间距为30微米，相邻所述第一遮光部40的列间间距为74微米，相邻所述第二遮光部50的行间间距为74微米，相邻所述第二遮光部50的列间间距为30微米，所述第一遮光部40和所述第二遮光部50的长度为54微米、宽度为10微米、高度为100微米。在另一个实施例中，相邻所述第一遮光部40的行间间距为50微米，相邻所述第一遮光部40的列间间距为140微米，相邻所述第二遮光部50的行间间距为140微米，相邻所述第二遮光部50的列间间距为30微米，所述第一遮光部40和所述第二遮光部50的长度为90微米、宽度为10微米、高度为167微米。
请参阅图10，图10是本申请提供的拼接面板100的第六结构示意图。本实施例与图9提供的拼接面板100不同的是，所述第一遮光部40包括：
第一凹槽311，所述封胶层31远离所述发光二极管灯板20的侧面设有所 述第一凹槽311，所述第一凹槽311内填充有遮光材料。
也即是，在上述实施例中，通过在所述封胶层31远离所述发光二极管灯板20的侧面设有所述第一凹槽311，并在第一凹槽311内填充有遮光材料，从而形成第一遮光部40，而且第一遮光部40位于所述封胶层31内，可以避免第一遮光部40被外力触碰而损坏。其中，所述遮光材料为黑色遮光材料。
所述第二遮光部50包括：
第二凹槽312，所述封胶层31远离所述发光二极管灯板20的侧面设有所述第二凹槽312，所述第二凹槽312内填充有遮光材料。
也即是，在上述实施例中，通过在所述封胶层31远离所述发光二极管灯板20的侧面设有所述第二凹槽312，并在第二凹槽312内填充有遮光材料，从而形成第二遮光部50，而且第二遮光部50位于所述封胶层31内，可以避免第二遮光部50被外力触碰而损坏。其中，所述遮光材料为黑色遮光材料。
另外，需要说明的是，在本申请其他实施例中，可以将所述第一遮光部40凸出设置在所述封胶层31远离所述发光二极管灯板20的侧面，而所述第二遮光部50设在所述封胶层31内；在本申请其他实施例中，可以将所述第一遮光部40设在所述封胶层31内，而所述第二遮光部50凸出设置在所述封胶层31远离所述发光二极管灯板20的侧面。
请参阅图11，图11是本申请提供的拼接面板100的第七结构示意图，图12是图11中A-A剖视图。本实施例与图9提供的拼接面板100不同的是，所述调光层30包括：
封胶层31，所述封胶层31覆盖在所述发光二极管灯板20上；
透明保护层32，所述透明保护层32设在所述封胶层31远离所述发光二极管灯板20的一侧，所述透明保护层32上设有多个所述第一遮光部40和多个所述第二遮光部50。
也即是，在本实施例中，将第一遮光部40和第二遮光部50设在透明保护层32上，可以增大第一遮光部40、第二遮光部50与发光二极管灯板20的间距，在为了获得相同视角的条件下，相对于将第一遮光部40和第二遮光部50设在封胶层31上的实施方式，将第一遮光部40和第二遮光部50设在透明保护层32上的实施方式可以使得第一遮光部40和第二遮光部50的高度较低，第一 遮光部40和第二遮光部50的高度具有更多的选择，因此本实施例可以具有更多视角效果选择。
另外，所述透明保护层32为透明玻璃或者涤纶树脂层。
