下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。
作为本公开的一方面，提供一种显示装置控制单元，包括：背板；多个电路结构，所述多个电路结构位于背板上；多个电场屏蔽结构，每个所述电场屏蔽结构位于所述电路结构之间，被配置为屏蔽所述电路结构之间的电场，其中，每个所述电场屏蔽结构包括多个屏蔽条，所述多个屏蔽条之间相互间隔且在所述电路结构对应侧边上的投影连续不间断。
下面结合图1至图4所示进行示例性说明，所述显示装置控制单元包括背板30，背板30上设置有多个电路结构40和用于对每个电路结构40进行 电场屏蔽的电场屏蔽结构，所述电场屏蔽结构包括环绕电路结构40的多个屏蔽条。所述多个屏蔽条包括：位于电路结构40的相对两侧的多个第一屏蔽条11和位于所述电路结构40其余两侧的多个第二屏蔽条21；位于电路结构40同一侧的第一屏蔽条11组成第一屏蔽结构10，位于电路结构40同一侧的第二屏蔽条21组成第二屏蔽结构20，两个第一屏蔽结构10沿电路结构40的预定散热方向排列。第一屏蔽结构10包括至少两个彼此间隔的第一屏蔽条11，每个第一屏蔽条11在两个第二屏蔽结构20排列方向的尺寸小于电路结构40在两个第二屏蔽结构20排列方向上的尺寸，第一屏蔽结构10在电路结构40对应侧边上的投影连续不间断。
应该注意的是，投影连续不间断意指屏蔽结构中所有屏蔽条的投影任意之间是没有间隙的，例如，相邻屏蔽条之间的投影边缘无缝连接或者投影彼此交叠。
所述显示装置控制单元尤其适用于立式的显示装置中，由于电路结构40工作时产生的热量主要是沿竖直方向散发的，因此，所述预定散热方向是指，当所述显示装置控制单元用在立式的显示装置中时的上下方向。在本公开中，所述预定散热方向为图2和图4中的上下方向。
在图2和图4中，两个第二屏蔽结构20沿左右方向排列，因此，第一屏蔽条11在两个第二屏蔽结构20排列方向上的尺寸为，第一屏蔽条11在电路结构40上的投影的左右方向的长度。
在本公开中，由于两个第一屏蔽结构10沿预定散热方向(即，热量散发的主要方向)排列，第一屏蔽结构10的第一屏蔽条11相互间隔，且第一屏蔽条11在两个第二屏蔽结构20排列方向的尺寸小于电路结构40在两个第二屏蔽结构20排列方向上的尺寸，因此，电路结构40产生的大部分热量沿预定散热方向散发时，会从相邻两个第一屏蔽条11之间的间隔向外扩散，从而提高了散热效果；并且，由于第一屏蔽结构10在电路结构40对应侧边上的投影连续不间断，而电磁波是沿直线方向传播的，因此，第一屏蔽条11之间的间隔并不会影响电场的屏蔽效果，从而在不影响电场屏蔽效果的情况下提高显示装置控制单元的散热效果，延长显示装置控制单元的使用寿命。
其中，为了提高屏蔽效果，第一屏蔽结构10在两个第二屏蔽结构20排列方向上的尺寸不小于电路结构40在两个第二屏蔽结构20排列方向上的尺寸；和/或，第二屏蔽结构20在所述预定散热方向上的尺寸不小于电路结构 40在所述预定散热方向上的尺寸。
在本公开中，为了实现第一屏蔽结构10在电路结构40上的投影连续无间断，每相邻两个第一屏蔽条11在电路结构40上的投影可以部分交叠或仅接触但不交叠。为了进一步便于热量向外扩散，例如，如图2和图4所示，同一个第一屏蔽结构10中，每相邻两个第一屏蔽条11在电路结构40对应侧边上的投影相接触且无重叠，也即，相邻两个第一屏蔽条11相互靠近的两端在所述预定散热方向上平齐。
需要说明的是，本公开中“相邻两个第一屏蔽条11”是指在该两个第一屏蔽条11在两个第二屏蔽结构20排列方向上的距离是最近的。例如，其中一个第一屏蔽结构10中的第一屏蔽条11的分布方式如图3所示，两个第二屏蔽结构(图3中未示出)仍沿左右方向排列，这时，与最左边的第一屏蔽条11相邻的是中间的第一屏蔽条11，而并非最右边的第一屏蔽条11。
本公开对第一屏蔽条11的延伸方向不作具体限定，例如，可以垂直于所述预定散热方向(如图1所示)，也可以与预定散热方向交叉但不垂直。例如，如图2和图4所示，至少一个第一屏蔽条11的延伸方向与所述预定散热方向的夹角在45°～90°之间。进一步，例如，每个第一屏蔽条11的延伸方向与所述预定散热方向的夹角均在45°～90°之间。与图1中的设置方式(即每个第一屏蔽条11的延伸方向均与所述预定散热方向垂直)相比，将第一屏蔽条11的延伸方向与所述预定散热方向的夹角设置在45°～90°之间更有利于散热。
下面结合图1至图4介绍电路结构40和第二屏蔽结构20的结构。电路结构40具体包括设置在背板30上的电路板41和设置在电路板41上的电子元件42，电路板41上靠近至少一个第二屏蔽结构20的边缘设置有信号端子43，信号端子43用于通过信号线44与其他电路结构40或信号端相连。
设置有信号端子43的边缘所对应的第二屏蔽结构20(图2和图4中电路结构40右侧的第二屏蔽结构20)包括至少两个彼此间隔的第二屏蔽条21，该第二屏蔽条21在电路结构40对应侧边上的投影在信号端子43处产生间断，所述电场屏蔽结构还包括包裹在信号端子43外部的电场屏蔽壳45(如图5所示)。因此，信号线44可以从右侧第二屏蔽条21之间的间隔中引出，而信号端子43外包裹的电场屏蔽壳45可以防止因右侧第二屏蔽条21之间的间隔导致的电场干扰。为了便于每个信号线44向外引出，设置有信号端子 43的边缘所对应的第二屏蔽结构20在电路结构40上的投影产生的间隔数量可以与信号端子43数量相同，例如，在图2和图4中，电路板41朝向右侧的第二屏蔽结构20的边缘设置有两个信号端子43，这时，第二屏蔽结构20可以包括三个彼此间隔的第二屏蔽条21，每相邻两个第二屏蔽条21之间的间隔位置对应一个信号端子43。其中，电场屏蔽壳45的高度可以大于所在电路板41上的电子元件42的高度，以提高屏蔽效果。
进一步地，信号端子43设置在电路板41靠近其中一个所述第二屏蔽结构20(图2和图4中右侧的第二屏蔽结构20)的边缘，电路板41靠近另一个第二屏蔽结构20(图2和图4中左侧的第二屏蔽结构20)的边缘未设置信号端子43。这种情况下，在另一个第二屏蔽结构20(图2和图4中左侧的第二屏蔽结构20)中，第二屏蔽条21的数量为至少两个且彼此间隔，第二屏蔽条21在所述预定散热方向上的尺寸小于电路结构40在预定散热方向上的尺寸，该第二屏蔽结构20在电路结构40对应侧边上的投影连续不间断。因此，电路结构40的热量沿左右方向扩散时，也可以从左侧第二屏蔽条21之间的间隔散出，进一步提高散热效果，而尽管左侧的相邻两个第二屏蔽条21之间有间隔，但其在电路结构40上的投影没有间隔，因此，第二屏蔽条21之间的间隔能够在进一步提高散热的同时不影响电场的屏蔽。
其中，在左侧第二屏蔽结构20中，相邻两个第二屏蔽条21在电路结构40上的投影可以没有交叠，也可以有部分交叠。在每个第二屏蔽结构20中，每个第二屏蔽条21均可以沿所述预定散射方向延伸。
本公开中的屏蔽条的材料、结构可以按照以下方式设置：
第一种设置方式为：第一屏蔽条11和/或第二屏蔽条21为与背板30形成为一体的金属条。第二种设置方式为：第一屏蔽条11和/或第二屏蔽条21包括填充块及包裹所述填充块的导电层，所述填充块具体可以为泡沫、海绵状结构，所述导电层具体可以为导电胶带。
即，第一屏蔽条11和第二屏蔽条21可以均为与背板30形成为一体的金属条；或者，均包括填充块及包裹所述填充块的导电层，或者，第一屏蔽条11和第二屏蔽条21中的一者为与背板30形成为一体的金属条，另一者包括填充块及包裹所述填充块的导电层。
为了保证相邻两个电路结构40之间的屏蔽条能够起到电场屏蔽的效果，其高度不能过小。两个电路结构40之间的屏蔽条的高度应不小于高度较小的 电路结构40上的电子元件42的最大高度，电子元件42的高度为电子元件42顶端到背板30与该电子元件42对应位置处的上表面的距离。进一步地，如图6所示，在任意相邻两个电路结构40中，当第一个电路结构40的高度小于第二个电路结构40的高度时(电路结构40的高度为电路结构40中高度最大的电子元件的高度)，该两个电路结构40之间的屏蔽条的高度H2，此高度H2为该屏蔽条顶端到背板30与该屏蔽条对应位置处的上表面的距离；H2满足：
H2≥(H3*L1+H1(L—L1))/L。
在上式中，H1为第一个电路结构40(即图6中左侧电路结构40)中的第一参考电子元件的高度，此高度为第一参考电子元件顶端到背板30与第一参考电子元件对应位置处的上表面的距离；H3为第二个电路结构40(即图6中右侧电路结构40)中的第二参考电子元件的高度，此高度为第二参考电子元件顶端到背板30与第二参考电子元件对应位置处的上表面的距离；L1为所述第一参考电子元件距离该两个电路结构40之间的屏蔽条最远的侧边到该两个电路结构40之间的屏蔽条距离所述第一参考电子元件最近的侧边的距离；L为所述第一参考电子元件距离所述第二参考电子元件最远的侧边到所述第二参考电子元件距离所述第一参考电子元件最远的侧边的距离。其中，所述第二参考电子元件为：第二个电路结构40中高度最大的电子元件42的高度；所述第一参考电子元件为：第一个电路结构40中顶端和所述第二参考电子元件顶端的连线与背板30之间夹角最小的电子元件42。图6中以两个电路结构40之间的屏蔽条为第二屏蔽条21进行表示说明，当然该两个电路结构40之间的屏蔽条也可以为第一屏蔽条11。
以上为对本公开提供的显示装置控制单元的描述，可以看出，在用于对电路结构40进行屏蔽的电场屏蔽结构中，由于第一屏蔽结构10的第一屏蔽条11相互间隔，且第一屏蔽条11在两个第二屏蔽结构20排列方向的尺寸小于电路结构40在两个第二屏蔽结构20排列方向上的尺寸，因此，电路结构40产生的大部分热量沿预定散热方向散发时，会从相邻两个第一屏蔽条11之间的间隔向外扩散，从而提高了散热效果；并且，由于电磁波是沿直线方向传播的，而第一屏蔽结构10在电路结构40相应侧边上的投影连续不间断，因此，第一屏蔽条11之间的间隔并不会影响电场的屏蔽效果，从而在不影响电场屏蔽效果的情况下提高显示装置控制单元的散热效果；另外，第二屏蔽 结构20包括至少两个彼此间隔的第二屏蔽条21，电路板41上的信号端子43外包裹有电场屏蔽壳45，可以避免因第二屏蔽条21之间的间隔导致的信号干扰；而未设置信号端子43处的边缘所对应的第二屏蔽结构20在电路结构40上的投影连续，在进一步提高散热效果的同时不会影响电场屏蔽效果。
作为本公开的第二个方面，提供一种显示装置，包括上述显示装置控制单元。其中，所述显示装置尤其可以为立式的显示装置。由于本公开的显示装置控制单元上电场屏蔽结构中，屏蔽条之间的间隔在提高散热效果的同时不会影响电场的屏蔽，使得显示装置控制单元的寿命延长，因此，采用所述显示装置控制单元的显示装置能够达到更好的散热效果和更优的质量。
本公开提供了一种显示装置控制单元和显示装置，由于两个第一屏蔽结构沿预定散热方向排列，第一屏蔽结构的第一屏蔽条相互间隔，且第一屏蔽条在两个第二屏蔽结构排列方向的尺寸小于电路结构在两个第二屏蔽结构排列方向上的尺寸，因此，电路结构产生的大部分热量沿预定散热方向散发时，会从相邻两个第一屏蔽条之间的间隔向外扩散，从而提高了散热效果；并且，由于第一屏蔽结构在电路结构上的投影连续不间断，而电磁波是沿直线方向传播的，因此，第一屏蔽条之间的间隔并不会影响电场的屏蔽效果，从而在不影响电场屏蔽效果的情况下提高显示装置控制单元的散热效果，延长显示装置控制单元以及采用该显示装置控制单元的显示面板的使用寿命。
显然，本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
