 附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，应当理解，以下附图仅示出了本发明的某些实施例，因此不应被看作是对范围的限定，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他相关的附图。
图1为本发明的一个实施例中LED载板的结构示意图；
图2为现有技术中一种LED载板的结构示意图；
图3为现有技术中另一种LED载板的结构示意图。
 本发明的最佳实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图图1至图3，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。通常在此处附图中描述和示出的本发明实施例的组件可以以各种不同的配置来布置和设计。
参见图1，在一个实施例中，本发明揭示了一种LED载板的布线结构，具体如下：
所述布线结构为三线制，只需要利用如下三类线布置线路：
第一类连接线，用于电性连接LED载板上每个LED发光体的供电正极/VCC端；
第二类连接线，用于电性连接LED载板上每个LED发光体的供电负极/GND端；
第三类连接线，用于电性连接LED载板上每个LED发光体的数据信号输入引脚DIN端以提供数据信号；
其中，
每个LED发光体包括该LED发光体的编码信息；
且每个LED发光体根据该LED发光体的编码信息，从所述数据信号中获取针对该LED发光体的对应数据信号。
对于上述实施例而言，其布线结构仅仅为三线制，且相比现有技术中断点续传的布线结构还免除了数据信号输出的线路。对于图1而言，其更多示意了线路和多个LED发光体，而没有示出LED载板。
将图1与图2对比，图2示意了现有技术中的一种布线结构：
图2的控制器虽然也只利用了一路数据信号，即DATA1，这一点与本发明图1所示的只有DIN一路数据信号表面上相同，但是：
在图2中沿着从右至左的顺序，却能够发现：图2中，其为了实现断点续传的功能，其DATA1不仅直接连接到第一个LED发光体的DIN1引脚，而且还连接到了第二个LED发光体的DIN2引脚，以此来确保，即使第一个LED发光体工作不正常导致其DOUT无法发出有效信号时，第二个LED发光体依然能够通过DIN2引脚获得来自DATA1的数据信号。如果第一个LED发光体工作正常，DOUT将转发出一个经过第第一个LED发光体所处理过的DATA1信号并传入第二个LED发光体的DIN1引脚。第三个LED发光体，类似。
显而易见，对于图2所示意的现有技术：其传输数据信号的主要引脚是DIN1，只有当DIN1收不到信号或工作不正常时，DIN2起到冗余的作用。而且，DIN1的信号默认来自前级的DOUT，DIN2的信号默认来自前级的DIN1。对于后级而言，该后级的DIN1中输入的信号本身经过了前级的处理，所以该后级能够直接获取该后级对应的数据信号；或者，该后级对于其DIN2中输入的信号，经过该后级按照固定处理算法处理，依然能使得该后级获取该后级对应的数据信号。换言之，即使图2中右侧，靠近控制器的第一个LED发光体工作不正常，其后级第二个LED发光体也会工作正常。只有第一个LED发光体、第二个LED发光体都故障时，其余后级才会出现大面积故障的情况。也就是说，对于图2所示的断点续传方案的布线结构，如果连续2个发光体或者其线路故障，那么相应的后级将整体故障。
本发明相比图2所示的现有技术，能完全免除掉DIN2引脚/端子以及对应的布线，因为本发明只需要布置DIN线这一种数据信号线路即可。同时，对应的，每个LED发光体本身有自身对应的编码信息，其只需要根据该LED发光体的编码信息，从所述数据信号中获取针对该LED发光体的对应数据信号即可，从而确保各个LED发光体正常工作。图2所示的现有技术则完全不依靠LED发光体的编码，而是：要么由前级处理数据信号后通过DOUT传给下一级，要么下一级根据DIN2的信号，按照固定的处理算法处理后，获取自身该级所需要的数据信号后，并继续通过DOUT向后传送。本发明中的编码信息指的是每个LED发光体的地址编码信息或ID编码信息，以区分各个LED发光体，该信息可以通过OTP的方式或其他烧录技术（基于浮栅、电容丝或反熔丝技术等）硬性存储在LED发光体中，并改变有关存储元件的状态以此固化、硬性的存储。
正是由于本发明能够免除掉DIN2此类冗余引脚和其连接前级DIN1的布线，以及免除掉后级DIN1连接前级DOUT的布线，而仅仅采用三线制连接所有的LED发光体，所以，本发明能够显著降低布线复杂度及其布线成本，也能够显著降低故障率改善良率。典型的，由于本发明中第三类连接线作为数据信号线，直接与每个LED发光体的DIN连接，而每个LED发光体有其自身的编码信息并正确的从数据信号线上获取到自身发光体所对应的数据信号，且每个LED发光体自身都连接对应的VCC和GND，那么，当任意一个LED发光体故障后，甚至连续两个LED发光体或者更多个发生故障后，本发明的布线结构依然能够确保其余发光体的工作。
另外，将本发明与图3所示的现有技术相比：
图3的控制器相比图2增添了一路数据信号，即DATA2，这一点与本发明图1所示的只有DIN一路数据信号不同。显而易见，图3相比图2的现有技术，线路更加复杂，更容易比图2所示的现有技术增加故障。
综上，本发明能够有效降低LED载板布线成本和改善良率。
在另一个实施例中，
所述LED载板为具有一定透光率的材料。
一定透光率，例如是接近完全透明的情况，或者是半透明的情况，这取决于LED载板希望达到什么样的视觉效果。此外，需要说明的是，由于本发明的布线数量减少，那么相应的焊点也将减少，对于同一透光率的LED载板，本发明的LED载板将进一步改善透明度。由于本发明布线数量减少，那么在满足透明度的前提下，本发明相比现有技术，更能够提高LED载板中布线的线宽以改善承受电流的能力。
在另一个实施例中，
所述LED载板为柔性的或硬性的载板。
在另一个实施例中，
所述线路设置在LED载板的一面。
此时，LED载板的另一面可以免除安装任何元器件，例如用于将采用此种布线方式的LED照明或显示产品贴敷安装于对应的目标物。
在另一个实施例中，
所述线路设置在LED载板的两面。
能够理解，其中，第一类连接线、第二类连接线、第三类连接线可以分别设置在LED载板的两面。典型的，当LED载板上设置有过孔时，可以根据需求将任意一种连接线自由的在LED载板的两面上进行设置，甚至通过过孔连通其线路。
在另一个实施例中，
所述LED载板具有如下任一特点：
（1）每个LED载板能够裁剪/切割成多个；
（2）每2个LED载板能够拼接成1个；
（3）所述多个LED发光体为并联关系。
对于上述实施例而言，所述LED载板可以设计为具有任意裁剪/切割的特性，因为裁剪/切割的时候，裁剪/切割所分开的2部分或更多部分，每一部分依然保有线路中的各类连接线，可用于一定数量LED发光体的电性连接。那么，只需要在裁剪/切割的时候，使得线路功能正常、对应部分的载板的承载功能正常即可。
至于每2个LED载板能够拼接成1个，只需要两个LED载板之间的第一类连接线、第二类连接线、第三类连接线彼此电性连接即可。
此外，对于每个LED载板而言，其中的多个LED发光体优选为并联关系，这是因为并联时，更加有利于裁剪/切割和拼接。优选为并联，意味着并不完全排除其他连接方式，无论串联或并联抑或混联，均需满足基本的耐电压、耐电流的要求。
在另一个实施例中，
所述第一类连接线、第二类连接线、第三类连接线，彼此平行。
在另一个实施例中，
所述多个LED发光体，设置为平行的多个行/列。
对于上述2个实施例，能够理解，各个连接线之间平行、多个LED发光体设置为平行的多个行/列，均有利于视觉效果、裁剪/切割和拼接。
在另一个实施例中，
所述第一类连接线、第二类连接线、第三类连接线，均设置为一层线路或两层线路。
在另一个实施例中，
所述第一类连接线、第二类连接线、第三类连接线上，分别设置有多个第一类型引脚、多个第二类型引脚、多个第三类型引脚；
每个第一类型引脚，用于电性连接每个LED发光体的供电正极/VCC端；
每个第二类型引脚，用于电性连接每个LED发光体的供电负极/GND端；
每个第三类型引脚，用于电性连接每个LED发光体的数据信号输入引脚DIN端以提供数据信号。
在另一个实施例中，所述LED发光体包括贴片式的LED。
在另一个实施例中，所述LED发光体包括：至少1个LED灯珠芯片和任何连接所述LED灯珠芯片的IC或其他元器件。
需要说明的是，就LED的发光而言，无论是AC还是DC驱动，LED自身最低要求是两线供电。由于LED芯片技术的发展，即使没有驱动IC，也能利用占用面积较小的一定数量LED芯片形成LED发光体，并直接被AC或DC驱动。
此外，需要说明的是，LED的驱动领域中，已经出现利用供电线例如零火线/正负极线，在供电的同时传送数据信号的技术。这相当于一种载波技术。这意味着，即使没有第三类连接线，只通过第一类连接线和第二类连接线，其同样能够传送数据信号。无论该数据信号是针对不同LED发光体、还是针对单个LED发光体中不同LED芯片的特定编码信号，无论该数据信号是具体LED发光体/LED芯片的地址编码信号、还是照明或显示的颜色的色彩信号，都可以利用此种载波技术实现相应数据信号的传送。
在另一个实施例中，
所述多个LED发光体等间距的设置。
在另一个实施例中，
所述LED载板上每一行/列的LED发光体，在该行/列内，相邻的LED发光体被等间距的设置。
能够理解，以上这两个实施例，均有利于实现等间距的视觉效果。
在另一个实施例中，
所述多个LED发光体之间，在线路上共地。
在另一个实施例中，
在载板正面的两端，还设置有：
用于电性连接LED发光体的数据信号输入引脚DIN端。
如此，即使涉及数据信号输入，所述载板同样能够与相同结构的载板前后级联。
在另一个实施例中，
