为更进一步阐述本发明为达成预定发明所采取的技术手段及功效，以下结合附图及较佳实施例，对依据本发明提出像素单元、像素矩阵及显示面板，其具体实施方式、结构、特征及其功效，详细说明如下。
现有技术下的像素单元包含有R、G、B三个像素子单元，由于每个像素子单元之间都有一根栅极信号线，每行列像素子单元之间都有一根数据信号线，而且在信号线与电极之间会设置一定的间距，信号线的布线区域以及预设的间隔空间会降低像素单元的有效开口率，进而降低显示面板的光透过率。
针对上述问题，本发明提供一种像素单元，该像素单元包括第一像素子单元、第二像素子单元和第三像素子单元，而第一像素子单元、第二像素子单元和第三像素子单元中至少两个像素子单元共用一个数据信号线。
本发明提供的像素单元，通过将像素单元中的多个像素子单元共用同一个数据信号线，同时将多个像素子单元的栅极信号线平行集中设置在像素单元内部，节省了布线空间，增加了像素单元的开口率，从而增加了显示面板光透过率，提升产品显示效果。
具体的，在本发明实施例中，至少两个像素子单元共用一个数据信号线可以为第一像素子单元、第二像素子单元和第三像素子单元中任意两个像素子单元共用同一个信号线。而在本发明的另一些实施例中，也可以为第一像素子单元、第二像素子单元和第三像素子单元三者共用同一个数据信号线。
如图1所示，为本发明提供的像素单元一实施例示意图，其中像素单元10包括第一像素子单元11、第二像素子单元12和第三像素子单元13，第一像素子单元11、第二像素子单元12和第三像素子单元13三者互相连接设置。
在本发明的实施例中，第一像素子单元11、第二像素子单元12和第三像素子单元13可以均为平行四边形结构。且第一像素子单元11、第二像素子单元12和第三像素子单元13三者互相连接组成像素单元10，而像素单元10为六边形结构。
具体的，第一像素子单元11、第二像素子单元12和第三像素子单元13可以均为菱形结构。
进一步的，第一像素子单元11、第二像素子单元12和第三像素子单元13可以均为等边长的菱形结构，且该菱形结构的两个顶角角度分别为60°和120°。此时由第一像素子单元11、第二像素子单元12和第三像素子单元13三者组成的像素单元10为正六边形结构。
如图2所示，为本发明实施例提供的像素单元局部放大图。在像素单元10中，存在有一个数据信号线，且该数据信号线同时控制三个像素子单元。具体的，该数据信号线在像素单元内部分出三个支线，且每一个支线分别与每一个像素子单元中的薄膜晶体管连接，用于控制像素子单元。由于使用一个数据信号线来控制三个像素子单元，减少了像素单元中的线路数目，节省了布线空间，从而增加了像素单元的开口率，增加了显示面板光透过率。
具体的，第一像素子单元11包括第一薄膜晶体管110和第一栅极信号线111，第二像素子单元12包括第二薄膜晶体管120和第二栅极信号线121，第三像素子单元13包括第三薄膜晶体管130和第三栅极信号线131。其中，第一栅极信号线111、第二栅极信号线121和第三栅极信号线131平行设置在像素单元10内部。
第一薄膜晶体管110、第二薄膜晶体管120和第三薄膜晶体管130都靠近像素单元10的正六边形结构中心120°的位置，且第一薄膜晶体管110、第二薄膜晶体管120和第三薄膜晶体管130在像素单元10的结构中心处分别与像素单元10中的数据信号线连接，三者共用同一个数据信号线。而第一像素子单元11、第二像素子单元12和第三像素子单元13中各自的栅极信号线平行设置在像素单元的内部，用以节省布线空间。
在上述实施例的中，第一像素子单元11、第二像素子单元12和第三像素子单元13三者共用一个数据信号线，即该数据信号线控制像素单元10中的三个像素子单元。减少了像素单元中的数据信号线的数量，节省了布线空间，从而增加了像素单元的开口率，增加了显示面板光透过率。
如图3所示，为本发明提供的像素单元另一实施例示意图。其中像素单元20包括第一像素子单元11、第二像素子单元12和第三像素子单元13，而第一像素子单元11为边长不相等的平行四边形结构。
具体的，第一像素子单元11为边长为m和n的平行四边形结构，而第二像素子单元12中与第一像素子单元11连接的第一边缘121与第一像素子单元11的第一边长111的长度相等。在本实施例中，若第一像素子单元11的第一边长111的长度为m，则第二像素子单元12的第一边缘121的长度也为m。
而第一像素子单元11的第二边缘112与第三像素子单元13的第一边缘131连接，第二像素子单元12的第二边缘122与第三像素子单元13的第二边缘132连接。此时第三像素子单元13的第一边缘131的长度等于第一像素子单元11的第二边缘112，即第三像素子单元的第一边缘长度为n。此时若第二像素子单元12的第二边缘122长度为p，则第三像素子单元13的第二边缘132的长度与第二像素子单元12的第二边缘122长度相等，即为p。
此时，第一像素子单元11为边长分别为m和n的平行四边形结构，第二像素子单元12为边长分别为m和p的平行四边形结构，第三像素子单元13为边长分别为n和p的平行四边形结构。且第一像素子单元11、第二像素子单元12和第三像素子单元13三者连接组成像素单元20。该像素单元20为六边形结构。且m、n、p三者不相等。
需要说明的是，在上述像素单元的实施例中，像素子单元的颜色可以为R、G、B三种颜色，但是在一个像素单元中，三个像素子单元的颜色均不相同。
本发明还提供一种像素矩阵，该像素矩阵包括多个像素单元，即多个像素单元相互连接形成了该像素矩阵。
本发明提供的像素矩阵，包括多个像素单元，通过将像素单元中的多个像素子单元共用同一个数据信号线，同时将多个像素子单元的栅极信号线平行集中设置在像素单元内部，节省了布线空间，增加了像素单元的开口率，从而增加了显示面板光透过率，提升产品显示效果。
在本发明的实施例中，多个像素单元相互连接可以呈蜂窝状，从而形成该像素矩阵。即多个像素单元呈蜂窝状连接依次向外延申排布，直至形成像素矩阵，覆盖整个显示面板。
需要说明的是，在上述实施例中，多个像素单元的结构可以相同也可以不同。且在本发明提供的像素矩阵实施例中，多个像素单元中至少有一个像素单元的结构如前述的像素单元实施例的结构，即像素矩阵的多个像素单元中，至少在一个像素单元中，第一像素子单元、第二像素子单元和第三像素子单元中至少两个像素子单元共用一个数据信号线。
具体的，形成像素矩阵的多个像素单元中，多个像素单元可以均为正六边形结构，此时组成像素单元的三个像素子单元均为结构相同，且边长相等的菱形结构。
需要说明的是，在上述实施例中，多个像素单元互相连接，且每个像素单元中又包括三个像素子单元，相邻两个像素单元中互相连接的两个像素子单元的颜色不同。
如图4所示，为本发明提供的像素矩阵一实施例局部放大图，像素矩阵包括第三像素单元41和第四像素单元42，其中像素单元41包括第四像素子单元411、第五像素子单元412和第六像素子单元413，像素单元42包括第七像素子单元421、第八像素子单元422和第九像素子单元423。
在该实施例中，第四像素子单元411、第五像素子单元412和第六像素子单元413分别为R、G、B三种颜色中的一种。具体的，第四像素子单元411可以为R，即红色；第五像素子单元412可以为G，即绿色；第六像素子单元413可以为B，即蓝色。
此时，由于第四像素单元42中的第八像素子单元423与第三像素单元41中的第五像素子单元412相互连接，第四像素子单元412为红色，则第八像素子单元423可以为蓝色或者绿色，在本实施例中，第八像素子单元423为蓝色。
本发明还提供一种显示面板，该显示面板包括前述的像素矩阵。本发明提供的显示面板，通过将像素矩阵中的像素单元中的多个像素子单元共用同一个数据信号线，同时将多个像素子单元的栅极信号线平行集中设置在像素单元内部，节省了布线空间，增加了像素单元的开口率，从而增加了显示面板光透过率，提升产品显示效果。
根据本发明的上述目的，提出一种像素矩阵，包括上述的像素单元。本实施例提供的像素矩阵的工作原理，与前述像素单元的实施例工作原理一致，具体结构关系及工作原理参见前述像素单元实施例，此处不再赘述。
根据本发明的上述目的，提出一种显示面板，包括上述的像素矩阵。本实施例提供的显示面板的工作原理，与前述像素矩阵的实施例工作原理一致，具体结构关系及工作原理参见前述像素矩阵实施例，此处不再赘述。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
