Description

像素结构、阵列基板及显示装置 技术领域
本申请涉及显示技术领域，尤其涉及一种像素结构、阵列基板及显示装置。
背景技术
液晶显示器(Liquid Crystal Display，LCD)是一种常用的电子设备，由于其具有功耗低、体积小、重量轻等特性，因此广泛受到用户青睐。目前的液晶显示装置主要是以薄膜晶体管(Thin Film Transistor,TFT)液晶显示器(TFT-LCD)为主。
在TFT-LCD中，多个像素单元呈矩阵式排布，每一像素单元包括红色(R)、绿色(G)和蓝色(B)三个子像素，每一子像素中包括相应颜色的滤光片。画面显示的颜色也即来自背光源的光线是由R、G、B三原色混合而成的，此为RGB技术。背光源的光线通过一种颜色的滤光片时，相应颜色的光线能够通过而其他颜色的光线不能通过。多个像素单元中不同的子像素开启或关闭，由此能够显示不同颜色的画面。
在RGB技术的基础上，还出现了WRGB技术，即在一个像素单元中增加了一白色子像素(W)，W子像素不会造成背光损失，因此WRGB技术的像素单元具有较高的穿透率，同时W子像素还可扩展色域。R、G、B、W子像素的面积均为1/4，纯色画面显示使用的面积为1/4，W子像素增加的同时，R、G和B子像素的面积均降低1/12(相同分辨率的情况下)，造成显示纯色画面 亮度偏低。虽然可以采用调整伽马电压的方式对R、G、B子像素进行处理以增加各自显示纯色画面时的亮度，但这种方式过于复杂，开发难度较大。

为了说明本申请所述的技术方案，以下结合具体附图及实施例进行详细说 明。
请参阅图1，本申请第一实施例提供一种像素结构，包括多个阵列式排布的像素单元1、多条沿行方向延伸且沿列方向间隔排列的扫描线2，以及多条沿列方向延伸且沿行方向间隔排列的数据线3。每一像素单元1包括多个三原色子像素组10以及多个第四子像素14，第四子像素14与三原色子像素组10按行方向交替设置，每一第四子像素14设于相邻两三原色子像素组10之间。
其中，三原色子像素组10包括第一子像素11、第二子像素12和第三子像素13，第一子像素11、第二子像素12和第三子像素13选自红色子像素、绿色子像素和蓝色子像素，且第一子像素11、第二子像素12和第三子像素13各不相同，第四子像素14的颜色与第一子像素11、第二子像素12和第三子像素13也不相同，第四子像素14选自除红色子像素、绿色子像素和蓝色子像素之外的白色子像素、黄色子像素或青色子像素。白色子像素或黄色子像素的光线透过率大于红色子像素、绿色子像素和蓝色子像素，因此，能够提高光线透过率，提高显示画面的亮度，青色子像素或黄色子像素的设置能够扩展显示画面的色域，使显示画面的色彩更多样。
每一第四子像素14设于相邻两三原色子像素组10之间，也即，对于每一像素单元1而言，第四子像素14的数量比三原色子像素组10的数量少1。相对于由四个子像素构成一个像素单元1的WRGB技术而言，本申请的像素单元1中节省出了一个第四子像素14的面积提供给多个三原色子像素组10使用，从而提高了三原色子像素组10中的过滤三原色的滤光面积，提高了纯色画面显示时的亮度，同时，本申请的像素单元1中还保证有多个也即至少两个第四子像素14，能够保证显示画面整体具有较高亮度和/或广色域。
两三原色子像素之间设置一第四子像素14，相当于两三原色子像素组10 之间共用一个第四子像素14。假设一三原色子像素组10与一第四子像素14作为一四色子像素组20，当相邻两个四色子像素组20显示画面时需要至少一个第四子像素14打开时，本申请的第四子像素14即打开，同时在其两侧的两个三原色子像素组10使用或在其中一个三原色子像素组10中使用，当相邻两个四色子像素组20所显示的画面均不需要第四子像素14的颜色时，两三原色子像素组10之间的第四子像素14关闭，由此实现了第四子像素14的共用。
作为一种实现方案，第四子像素14的共用可以通过设置一比较器实现。比较器的两个输入端分别连接至源极驱动器的两个数据信号，比较器的输出端连接至与第四子像素14连接的数据线3，比较器的输出端始终输出两个输入的数据信号中较大的一个，从而实现当相邻两个四色子像素组20所显示的画面需要至少一个第四子像素14的颜色时，本申请的第四子像素14即打开。
如图1所示，三原色子像素组10中第一子像素11、第二子像素12和第三子像素13也按行方向依次排列。在一像素单元1中，第一子像素11、第二子像素12、第三子像素13和第四子像素14同时连接至一条扫描线2，第一子像素11、第二子像素12、第三子像素13和第四子像素14各自连接至一条数据线3。
第一子像素11、第二子像素12、第三子像素13和第四子像素14均位于数据线3的同一侧，这样的好处在于，即使在相同显示面积内，因数据线3数量增多而造成相邻两条数据线3之间的距离需要降低，由于相邻两条数据线3之间以第一子像素11、第二子像素12、第三子像素13或第四子像素14间隔开，不会造成相邻两条数据线3之间形成电容效应造成负载过大或对数据线3的制程造成影响，保证了显示效果。
可选地，第一子像素11、第二子像素12、第三子像素13和第四子像素 14的面积可以均相等，第一子像素11、第二子像素12、第三子像素13和第四子像素14均呈沿列方向延伸的长方形，像素单元1呈沿行方向延伸的长方形。第一子像素11、第二子像素12、第三子像素13面积也可以不完全相等，如增大红色子像素的面积来降低色温或增大蓝色子像素的面积来提高色温，以适应不同显示面板的色温需求。
由于本申请的像素单元1中每一第四子像素14设于相邻两三原色子像素组10之间，第四子像素14的数量比三原色子像素组10的数量少1，在一像素单元1中第四子像素14的数量越少，则三原色子像素组10的面积增大越多，纯色画面显示的亮度提高越明显，第四子像素14的面积降低越大，对显示画面整体亮度和色域影响越大。
具体地，如图1所示，一像素单元1中的第四子像素14的数量为3，三原色子像素组10的数量为4。当第一子像素11、第二子像素12、第三子像素13和第四子像素14的面积均相等时，则第一子像素11、第二子像素12、第三子像素13和第四子像素14的面积均为像素单元1面积的1/15，提供给纯色画面显示的面积为4/15(4个红色子像素、4个绿色子像素或4个蓝色子像素)，提供给每一纯色画面显示的面积增大了1/60，第四子像素14的面积减少了1/20。
可以理解的是，对于第四子像素14不开启的任何其他画面的显示，也即由红色子像素、绿色子像素和蓝色子像素中的至少两个个开启时所混合得到的显示画面，亮度也得以提高。本申请仅使得只有第四子像素14单独开启的情况下的亮度降低3/60，而只有第四子像素14单独开启的概率极低，故，从显示画面整体来看，本申请既能够使得每一纯色画面的亮度得以明显提高，又对显示画面整体的亮度和色域影响较小。
提供一比较例，一像素单元1中的第四子像素14的数量为1，三原色子像素组10的数量为2，即两个三原色子像素组10之间共用一个第四子像素14，第一子像素11、第二子像素12、第三子像素13和第四子像素14的面积均为像素单元1面积的1/7，提供给纯色画面显示的面积为2/7(2个红色子像素、2个绿色子像素或2个蓝色子像素)，提供给纯色画面显示的面积增大了1/28，第四子像素14的面积减少了3/28，与第一实施例相比较，对显示画面整体的亮度影响相对大。
可选地，一像素单元1中第四子像素14的数量还可以为2或4，均可使得每一纯色画面的亮度得以明显提高的同时还对显示画面整体的亮度和色域影响较小。
该第一实施例的像素结构适用于液晶显示装置，也适用于顶发光型或底发光型的OLED(有机发光二极管，Organic Light-Emitting Diode)显示装置。
请参阅图2，为本申请第二实施例提供的像素结构。与第一实施例不同的是，第四子像素14与三原色子像素组10按列方向交替设置，并且，在三原色子像素组10中第一子像素11、第二子像素12和第三子像素13也按列方向依次排列。在一三原色子像素组10中的第一子像素11、第二子像素12、第三子像素13和第四子像素14同时连接至一条数据线3，第一子像素11、第二子像素12、第三子像素13和第四子像素14各自连接至一条扫描线2。
相对于第一实施例，本申请第二实施例还具有的有益效果在于：扫描线2的数量增加，数据线3的数量减少，相应的栅极驱动器的数量增加而源极驱动器的数量可以减少，基于源极驱动器比栅极驱动器的成本更低，还可以降低结构成本。
第一子像素11、第二子像素12、第三子像素13和第四子像素14均位于 扫描线2的同一侧，这样的好处在于，即使在相同显示区面积内，因扫描线2的数量增多而造成相邻两条扫描线2线之间的距离需要降低，由于相邻两条扫描线2线之间以第一子像素11、第二子像素12、第三子像素13或第四子像素14间隔开，不会造成相邻两条扫描线2线之间形成电容效应造成负载过大或对扫描线2的制程造成影响，保证了显示效果。
第一子像素11、第二子像素12、第三子像素13和第四子像素14的面积均相等，第一子像素11、第二子像素12、第三子像素13和第四子像素14均呈沿行方向延伸的长方形，像素单元1呈沿列方向延伸的长方形。
该第二实施例的像素结构适用于液晶显示装置，也适用于顶发光型或底发光型的OLED显示装置。
请参阅图3，为本申请第三实施例提供的像素结构，第四子像素14与三原色子像素组10按行方向交替设置，第一子像素11、第二子像素12和第三子像素13按列方向依次排列。
一三原色子像素组10中的第一子像素11、第二子像素12和第三子像素13同时连接至一条数据线3，第四子像素14连接至相邻一条数据线3，第一子像素11、第二子像素12和第三子像素13各自连接至一条扫描线2，第四子像素14可以与该三条扫描线2中的任意一条连接。
该第三实施例相对于第一实施例，可以减少数据线3的数量，相对于第二实施例可以减少扫描线2的数量，从而有利于数据线3和扫描线2之间的距离设置和制程。
该第三实施例中，第四子像素14在列方向上是对应第一子像素11、第二子像素12和第三子像素13，该像素结构尤其适用于顶发光型的OLED显示装置。分别与第一子像素11、第二子像素12和第三子像素13连接的三条扫描 线2与第四子像素14的投影重叠，有机发光二极管发出的光线直接从第四子像素14的阳极至阴极方向出射，无需经过第四子像素14的阳极下方的多条扫描线2，因此不会对像素开口率造成影响(参考附图8)。
对应地，图4所示为本申请第四实施例提供的像素结构，第四子像素14与三原色子像素组10按列方向交替设置，第一子像素11、第二子像素12和第三子像素13按行方向依次排列。一三原色子像素组10中的第一子像素11、第二子像素12和第三子像素13同时连接至一条数据线3，第四子像素14连接至相邻一条扫描线2，第一子像素11、第二子像素12和第三子像素13各自连接至一条数据线3，第四子像素14可以与该三条数据线3中的任意一条连接。
该第四实施例相对于第一实施例，同样可以减少数据线3的数量，相对于第二实施例可以减少扫描线2的数量，从而有利于数据线3和扫描线2之间的距离设置和制程。
该第四实施例的像素结构尤其适用于顶发光型的OLED显示装置，不再赘述。
当然，三原色子像素组10中的第一子像素11、第二子像素12和第三子像素13还可以呈两行或两列排列。如图5所示，本申请第五实施例的像素结构，一三原色子像素组10中的第一子像素11设于一行，第二子像素12和第三子像素13设于另一行，第一子像素11和第四子像素14同时连接至一条扫描线2，第二子像素12和第四子像素14同时连接至相邻一条扫描线2，第一子像素11和第二子像素12同时连接至一条数据线3，第三子像素13连接至相邻一条数据线3。相比于第一实施例可进一步减少数据线3的数量，相对于第二实施例，可减少扫描线2的数量。
可选地，第三子像素13和与其相邻的一个第四子像素14可同时连接至一条数据线3，以进一步减少数据线3的数量，降低制程成本。
该第五实施例的像素结构尤其适用于顶发光型的OLED显示装置，不再赘述。
本申请还提供一种阵列基板5，如图6所示，阵列基板5包括衬底基层50，衬底基层50上包括显示区和设于显示区周围的非显示区，显示区内设有上述第一实施例至第五实施例所说的像素结构。
本申请还提供一种显示装置，包括上述所说的阵列基板5。
在一实施例中，显示装置200是液晶显示装置，如图7所示，其阵列基板5包括第一实施例和第二实施例的像素结构，阵列基板5、与该阵列基板5对置的彩膜基板6以及夹设于阵列基板5与彩膜基板6之间的液晶层7构成液晶显示面板，阵列基板5一侧还设有背光模组8，背光模组8与液晶显示面板构成液晶显示装置。
在一实施例中，显示装置200’是OLED显示装置，如图8所示，其阵列基板5包括上述第一实施例至第五实施例所说的像素结构，阵列基板5与封装盖板9封装构成一OLED显示装置。
以上仅为本申请的可选实施例而已，并不用于限制本申请。对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
