Description

显示面板及其阵列基板
【技术领域】
本发明涉及显示面板技术领域，具体是指一种显示面板及其阵列基板。
【背景技术】
在液晶显示面板技术中，RGBW四色型像素设计相对于传统的RGB三原色像素设计而言，增加一个W白色子像素，以增加液晶显示面板的显示亮度，降低背光的功耗。其中，当同一像素单元中的R、G、B三个子像素全开时，W子像素才会开启，否则，W子像素就处于关闭的状态。
因此，在RGBW显示面板显示纯色或者彩色画面时，与RGB液晶显示面板相比，在同样的背景显示画面下，RGBW面板的纯色亮度就会降低，显示画面失真，严重影响显示画面的光学品味。
【发明内容】
本发明提供一种显示面板及其阵列基板，以解决现有技术中RGBW显示面板的亮度低、显示画面失真以及影响显示画面的光学品味的技术问题。

根据本发明一实施例，所述多个彩色子像素分别为红色子像素、绿色子像素和蓝色子像素。
为解决上述技术问题，本发明采用的另一个技术方案是：提供一种显示面板，包括上述所述的阵列基板、与所述阵列基板相对设置的公共基板以及夹持于所述阵列基板与所述公共基板之间的液晶层。
根据本发明一实施例，在同一所述像素单元中，所述多个彩色子像素均开启时，所述白色子像素开启。

【具体实施方式】
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1和图2，图1是本发明提供的阵列基板第一实施例的结构示意图，图2是第一实施例中像素单元的结构示意图。
如图1所示，该阵列基板100包括多个像素单元10，每一像素单元10包括多个彩色子像素和一白色子像素12，多个彩色子像素分别为红色子像素14、绿色子像素16和蓝色子像素18；每一子像素包括子像素电极以及与每一子像素电极对应设置的子像素开关，多个子像素开关设置在白色子像素12内，从而提高彩色子像素的开口率。
本发明提供的阵列基板100由于设有子像素开关，且多个子像素开关设置在同一白色子像素12内，从而可以降低白色子像素12的亮度，同时增大多个彩色子像素的开口率，进而降低彩色画面的失真度，提升彩色画面的光学品味。
具体参见图2，每一子像素包括子像素电极以及与每一子像素电极对应设置的子像素开关，具体的，白色子像素12包括白色子像素电极122以及与白色子像素电极122对应设置的白色子像素开关124，红色子像素14包括红色子像素电极142以及与红色子像素电极142对应设置的红色子像素开关144，绿色子像素16包括绿色子像素电极162以及与绿色子像素电极162对应设置的绿色子像素开关164，蓝色子像素18包括蓝色子像素电极182以及与蓝色子像素电极182对应设置的蓝色子像素开关184，其中，白色子像素开关124、红色子像素开关144、绿色子像素开关164以及蓝色子像素开关184均设置白色子像素12内。
其中，像素单元10呈矩阵式排列，白色子像素12设置于矩阵式排列像素单元的任一格。具体的，像素单元10呈“田”字形，白色子像素12设置于“田”字形像素单元10的任一格，白色子像素12设置在“田”字形像素单元10的左上空格，在其他实施例中，白色子像素12还可以设置在“田”字形像素单元10的左下、右上或者右下空格。还有其他实施例中，像素单元呈“—”字形或者“|”字形，即多个子像素设置在一行或一列，白色子像素设置于其中一格，只需要各个子像素开关设置在白色子像素内即可。
在同一像素单元10中，只有当红色子像素14、绿色子像素16以及蓝色子像素18均开启时，白色子像素12才开启，即输出对应颜色的光线。白色子像素12使得阵列基板100在显示相同亮度的画面时，其耗电量更低或者在相同功耗的情况下，亮度大幅提高。但当显示纯色画面或者只需两个颜色的显示画面时，白色子像素12不开启，白色子像素12会影响显示画面的色彩纯度，从而导致显示画面色彩失真。因此，在同一像素单元中，当多个彩色子像素均开启时，白色子像素才开启。
请参阅图3，图3是本发明提供的阵列基板第二实施例的结构示意图。
本实施例中，子像素开关为薄膜晶体管，子像素开关的第一连接端、第二连接端以及控制端分别对应于薄膜晶体管的漏极、源极以及栅极。具体以白色子像素22的子像素开关224为例，子像素开关224为薄膜晶体管TFT，子像素开关224的第一连接端2242、第二连接端2244以及控制端2246分别对应于薄膜晶体管TFT的漏极、源极以及栅极，其他彩色子像素的子像素开关依此类推，此处不再赘述。以下的子像素开关均以白色子像素22的子像素开关224为例。
如图3所示，阵列基板200进一步包括多条扫描线23和多条数据线25，其中，每一像素单元内的各子像素的第一连接端2242连接至对应的子像素电极222，每一像素单元内的各子像素的第二连接端2244连接至对应的数据线25上，每一像素单元内的各子像素的控制端2246连接至对应的扫描线23上。
本实施例的阵列基板200排列方式，使得白色子像素22内的多个子像素开关还包括虚拟子像素开关226。目前，市场上的显示面板设计均为偶数行，按照本实施例的排列方式，偶数行设计需要特别设计第一行以及最后一行，当第一行对应的白色子像素22上方没有其他的子像素时，只有左边的子像素以及本身白色子像素22，只需要两个薄膜晶体管TFT，为了维持整个面板白色子像素22的开口率一致，故需要在第一行的白色子像素22中设计两个虚拟子像素开关226，其中，虚拟子像素开关226只是为了开口率一致，并不工作；当最后一行对应的其他两个彩色子像素下方没有白色子像素22时，为了保证最后一行的子像素开口率与整个显示面板的子像素开口率一致，故将最后一行对应的子像素的薄膜晶体管TFT设计在对应的子像素显示区下方。
本发明实施例的阵列基板200无需通过绕线的方式即可实现，能有效减小各个子像素之间寄生电容的产生，同时，本发明在不改变原有RGBW演算法的同时，能有效的增大R、G、B三个子像素的开口率，降低RGBW四色显示画面下，纯色或者彩色画面的失真的情况，同时也不会影响显示面板的亮度。
子像素开关为薄膜晶体管TFT，当薄膜晶体管TFT设计在彩色子像素内，而薄膜晶体管TFT是不导光的，因此彩色子像素都会有一定的开口率损失。而本发明将一个像素单元内的多个子像素开关均设置在同一白色子像素内，可以增大多个彩色子像素的开口率，开口率从原先的50%左右提高至70%，而白色子像素的相应开口率减少，从而使得白色子像素的亮度降低，也可以降低白色光对彩色画面的影响，提升彩色画面的品质。
请参阅图4，图4是本发明提供的显示面板第一实施例的结构示意图；
如图4所示，该显示面板1包括上述所述的阵列基板100、与上述所述的阵列基板100相对设置的公共基板101以及夹持于所述阵列基板与所述公共基板之间的液晶层102。
其中，阵列基板100的结构参见上文，此处不再重复赘述。
请参阅图5，图5是本发明提供的显示装置第一实施例的结构示意图。
如图5所示，该显示装置2，包括壳体201以及上述所述的显示面板1，显示面板1设置在壳体201内部。
其中，显示面板1和阵列基板300的结构参见上文，此处不再重复赘述。
综上所述，本领域技术人员容易理解，本发明提供的阵列基板由于设有子像素开关，且多个子像素开关设置在同一白色子像素内，从而可以降低白色子像素的亮度，同时增大多个彩色子像素的开口率，进而降低彩色画面的失真度，提升彩色画面的光学品味。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
