具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。为使显示装置显示的画面更清晰，常采用点反转驱动方式驱动显示装置，采用点反转驱动方式驱动显示装置时，任意相邻的两个子像素的极性相反。
发明人发现，当RGBW子像素的排布方式如图1(a)所示时，同一行中相邻两个像素中颜色相同的两个子像素的极性相同(图1(a)中以“+”和“-”代表子像素的极性)，因而当显示装置整体或部分显示一种彩色时，画面中会出现水平条纹，使得画面不清晰；当RGBW子像素的排布方式如图1(b)所示时，任意相邻两个像素中颜色相同的两个子像素的极性相同(图1(b)中以“+”和“-”代表子像素的极性)，因而当显示装置整体或部分显示一种彩色时，画面会出现闪烁现象。
本发明实施例提供了一种像素结构，在提高RGBW像素结构中子像素的混色均匀度同时，可以实现在采用点反转驱动方式驱动显示装置时，不会出现水平条纹或者画面闪烁的现象。
实施例一
本发明实施例提供了一种像素结构，在提高RGBW像素结构中子像素的混色均匀度同时，可以实现在采用点反转驱动方式驱动显示装置时，不会出现水平条纹或者画面闪烁的现象。
该像素结构包括多个重复单元，每个重复单元包括呈“田”字分 布或排列成两行两列的矩阵的形状的第一部分、第二部分、第三部分和第四部分，举例而言，上述第二部分位于第一部分的右方，第三部分位于第一部分的下方，第四部分位于第二部分的下方；其中，第一部分至第四部分均包括四行四列子像素，且第一部分至第四部分的每一行、每一列以及对角线上均包括一个红色子像素R、一个绿色子像素G、一个蓝色子像素B和一个白色子像素W；任意左右相邻两部分中位于四行中的同一行中的颜色相同的两个子像素分别位于一个部分中的奇数列和另一个部分中的偶数列；任意上下相邻两部分中位于四列中的同一列中的颜色相同的两个子像素分别位于一个部分中的奇数行和另一个部分中的偶数行。
具体地，为了便于本领域技术人员理解，本发明实施例以第一部分为例，详细说明如何保证第一部分的每一行、每一列以及对角线上均包括一个红色子像素R、一个绿色子像素G、一个蓝色子像素B和一个白色子像素W。
举例而言，如图2所示，当第一部分第一行中子像素的排布方式为：R、G、B、W时，为保证上述第一列中及主对角线上的子像素颜色不同，上述主对角线为从左上至右下的对角线，第二行中红色子像素R只能位于第二行第三列或第二行第四列，本发明实施例中第二行中红色子像素R位于第三列；进一步地，为保证第二列中及副对角线上的子像素颜色不同，上述副对角线为左下至右上的对角线，副对角线上的绿色子像素G只能位于第四行第一列，副对角线上的蓝色子像 素B只能位于第三行第二列；类似地，依次确定第一列中蓝色子像素B位于第二行，第一列中白色子像素W位于第三行，第二行中白色子像素W位于第二列，第二行中绿色子像素G位于第四列，第三行中绿色子像素G位于第三列，第三行中红色子像素R位于第四列，第四行中白色子像素W位于第三列，第四行中蓝色子像素B位于第四列。同理可知，当第二行的红色子像素R位于第二行第四列时，第二行子像素的排布方式：W、B、G、R，第三行的排布方式为：G、R、W、B，第四行的排布方式为：B、W、R、G。
除上述两种排布方式外，第一部分中子像素的排布方式还可为多种，只需保证第一部分中每一行、每一列以及对角线上均包括一个红色子像素R、一个绿色子像素G、一个蓝色子像素B和一个白色子像素W即可，此处不再一一列举。
采用类似地排布方式即可保证上述第二部分至第四部分中子像素的排布方式满足：每一行、每一列以及对角线上均包括一个红色子像素R、一个绿色子像素G、一个蓝色子像素B和一个白色子像素W。
为了便于本领域技术人员理解，本发明实施例提供了一种具体的实施方式以保证任意左右相邻两部分中位于同一行中的颜色相同的两个子像素分别位于一个部分中的奇数列和另一个部分中的偶数列。
具体地，该实施方式为：一个部分中奇数列的子像素的排布方式与与之左右相邻的另一部分中偶数列的子像素的排布方式相同，一个部分中偶数列的子像素的排布方式与与之左右相邻的另一部分中奇 数列的子像素的排布方式相同。例如，一个部分中第一和第三列的子像素的排布方式与与之左右相邻的另一部分中第二和第四列的子像素的排布方式分别相同，一个部分中第二和第四列的子像素的排布方式与与之左右相邻的另一部分中第一和第三列的子像素的排布方式分别相同。举例而言，本发明实施例中第二部分位于第一部分的右方，第一部分中子像素的排布方式如图3(a)所示，第一部分中第一列子像素的排布方式为：R、B、W、G，第二列子像素的排布方式为：G、W、B、R，第三列子像素的排布方式为：B、R、G、W，第四列子像素的排布方式为：W、G、R、B，由以上实施方式即可确定第二部分中子像素的排布方式如图3(b)所示，第二部分中第一列子像素的排布方式为：G、W、B、R，第二列子像素的排布方式为：R、B、W、G，第三列子像素的排布方式为：W、G、R、B，第四列子像素的排布方式为：B、R、G、W。
此外，为了便于本领域技术人员理解，本发明实施例还提供了一种具体的实施方式以保证任意上下相邻两部分中位于同一列中的颜色相同的两个子像素分别位于一个部分中的奇数行和另一个部分中的偶数行。
具体地，该实施方式为：一个部分中奇数行的子像素的排布方式与与之上下相邻的另一部分中偶数行的子像素的排布方式相同，一个部分中偶数行的子像素的排布方式与与之上下相邻的另一部分中奇数行的子像素的排布方式相同。例如，一个部分中第一和第三行的子 像素的排布方式与与之上下相邻的另一部分中第二和第四行的子像素的排布方式分别相同，一个部分中第二和第四行的子像素的排布方式与与之上下相邻的另一部分中第一和第三行的子像素的排布方式分别相同。
举例而言，本发明实施例中第三部分位于第一部分的下方，第一部分中子像素的排布方式如图3(a)所示，第一部分中第一行子像素的排布方式为：R、G、B、W，第二行子像素的排布方式为：B、W、R、G，第三行子像素的排布方式为：W、B、G、R，第四行子像素的排布方式为：G、R、W、B，由以上实施方式即可确定第二部分中子像素的排布方式如图3(c)所示，第三部分中第一行子像素的排布方式为：B、W、R、G，第二行子像素的排布方式为：R、G、B、W，第三行子像素的排布方式为：G、R、W、B，第四行子像素的排布方式为：W、B、G、R。
进一步地，当第一部分、第二部分确定后，第四部分位于第二部分下方，如图3(d)所示，第四部分中子像素的排布方式可以根据第二部分中子像素的排布方式由以下方式确定：任意上下相邻两部分中位于同一列中的颜色相同的两个子像素分别位于一个部分中的奇数行和另一个部分中的偶数行；也可以当第一部分和第三部分确定后，第四部分中子像素的排布方式由第三部分的子像素的排布方式根据以下方式确定：任意上下相邻两部分中位于同一列中的颜色相同的两个子像素分别位于一个部分中的奇数行和另一个部分中的偶数行。
由以上重复单元中第一部分、第二部分、第三部分和第四部分中子像素的排布方式可知，当重复单元中第一部分中子像素的排布方式确定后，重复单元的子像素的排布方式也相应地确定，因而当重复单元中第一部分的子像素具有多种排布方式时，重复单元的子像素的排布方式也相应地有很多种。以上仅描述了一种重复单元的子像素的排布方式，对于重复单元的子像素的其他排布方式，此处不再赘述。
进一步地，本发明实施例提供了一种具体的重复单元中子像素的排布方式，如图3所示，该具体的重复单元中子像素的排布方式为：第一部分中第一行中的子像素排布方式为：R、G、B、W，第二行中的子像素排布方式为：B、W、R、G，第三行中的子像素排布方式为：W、B、G、R，第四行中的子像素排布方式为：G、R、W、B；第二部分位于第一部分右方，第二部分中第一行中的子像素排布方式为：G、R、W、B，第二行中的子像素排布方式为：W、B、G、R，第三行中的子像素排布方式为：B、W、R、G，第四行中的子像素排布方式为：R、G、B、W；第三部分位于第一部分下方，第三部分中第一行中的子像素排布方式为：B、W、R、G，第二行中的子像素排布方式为：R、G、B、W，第三行中的子像素排布方式为：G、R、W、B，第四行中的子像素排布方式为：W、B、G、R；第四部分位于第二部分下方，第四部分中第一行中的子像素排布方式为：W、B、G、R，第二行中的子像素排布方式为：G、R、W、B，第三行中的子像素排布方式为：R、G、B、W，第四行中的子像素排布方式为：B、W、R、G。
在一些实施例中，每个子像素的面积相等且均为四边形。例如，每个子像素均为正方形。
本发明实施例提供了一种像素结构，该像素结构包括多个重复单元，首先，每个重复单元包括排列成两行两列的矩阵的形状的第一部分、第二部分、第三部分和第四部分；其次，第一部分至第四部分均包括四行四列子像素，且第一部分至第四部分的每一行、每一列以及对角线上均包括一个红色子像素R、一个绿色子像素G、一个蓝色子像素B和一个白色子像素W；然后，任意左右相邻两部分中位于同一行中的颜色相同的两个子像素分别位于一个部分中的奇数列和另一个部分中的偶数列，任意上下相邻两部分中位于同一列中的颜色相同的两个子像素分别位于一个部分中的奇数行和另一个部分中的偶数行。当采用点反转驱动方式驱动显示装置时，由于本发明实施例提供的像素结构中子像素的排布方式如上所述，在提高RGBW像素结构中子像素的混色均匀度同时，使得同一行中相邻两个像素中颜色相同的两个子像素的驱动极性相反，且同一列中相邻两个像素中颜色相同的两个子像素的驱动极性相反，因而当显示装置整体或部分显示一种彩色时，不会出现水平条纹、竖直条纹或者画面闪烁的现象。
此外，本发明实施例还提供了一种显示基板，该显示基板包括以上任一种实施方式中的像素结构。
实施例二
本发明实施例还提供了一种显示装置，该显示装置包括以上实施 方式中的显示基板。该显示装置可以为：液晶面板、平板电脑、电视机、显示器、笔记本电脑、电子纸、手机、数码相框、导航仪等任何具有显示功能的产品或部件。例如，采用点反转驱动方式驱动该显示装置，显示装置在显示过程中，任意相邻的两个子像素的驱动极性相反。
本发明实施例提供了一种显示装置，该显示装置包括以上实施方式中的显示基板，当采用点反转驱动方式驱动显示装置时，由于本发明实施例中显示基板中像素结构中子像素具有如实施例一中的排布方式，在提高RGBW像素结构中子像素的混色均匀度同时，进而使得同一行中相邻两个像素中同颜色的两个子像素的极性相反，且同一列中相邻两个像素中同颜色的两个子像素的极性相反，因而当显示装置整体或部分显示一种彩色时，显示画面不会出现水平条纹、垂直条纹与画面闪烁的现象。
尽管上面以RGBW像素结构为例描述了本发明，但是本发明不限于上述实施例，例如本发明的构思同样适用于其它的诸如RGBY像素结构的像素结构。
以上实施方式仅用于说明本发明，而并非对本发明的限制，有关技术领域的普通技术人员，在不脱离本发明的精神和范围的情况下，还可以做出各种变化和变型，因此所有等同的技术方案也属于本发明的范畴，本发明的专利保护范围应由权利要求限定。
