Description

一种四色显示器的驱动方法及装置
本发明要求2015年8月21日递交的发明名称为“一种四色显示器的驱动方法及装置”的申请号201510519207.4的在先申请优先权，上述在先申请的内容以引入的方式并入本文本中。
技术领域
本发明涉及电子技术领域，尤其涉及一种四色显示器的驱动方法及装置。
背景技术
显示器显示原色为RGB三色组成，即白色由红色(R)、绿色(G)以及蓝色所组成(B)。但是，因为LCD非自发光系统，各种颜色均由背光模组所发出的光经过三色彩色滤光片后形成红绿蓝三色之后进行混色，但是此过程对于整体LCD的功耗有很大的影响。为了降低LCD的功耗，提出了一种由W(white，白色)RGB四色组成的显示器，W子像素的加入能大幅提高LCD的穿透率进而降低整体功耗。
在现有技术方案中，显示面板中由RGBW四个子像素组成的像素结构中采用横向正负正负(+-+-)的像素驱动方式，如图1所示，以RGBW四个子像素为一个像素，施加的信号以正负正负(+-+-)为基本单位从左向右重复，采用上述像素驱动方式进行图像显示时，若显示画面为灰度图像，每个像素中的四种颜色的子像素的极性平衡，相邻的像素之间的极性也平衡，因此，显示面板可以显示正常图像。但是，如图2所示，若显示画面为红色图像，每个像素显示红色的子像素，由于每个像素中的红色的子像素均为正极性，造成相邻的像素之间的极性不平衡，因此容易产生画面闪烁并衍生出影像残留的缺陷，同时导致影响画面品质。

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，所描述的实施例是本发明一部分实施例，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作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。
请参考图3，图3是本发明提出的一种四色显示器的驱动方法的第一实施例的流程图。如图所示，本发明实施例中的方法包括：
S301，对每行的多个像素进行分组得到像素组，其中，所述多个像素中的每个像素包括四种不同颜色的子像素，所述像素组包括相邻的四种不同颜色的子像素。
具体实现中，显示面板中各像素可以由四种颜色不同的子像素组成，每个像素呈阵列排列，各像素组包括相邻的四种不同颜色的子像素，例如：各像素分别包括红R、绿G、蓝B、白W四种不同颜色的子像素，将每行像素进行分组，以相邻的四个子像素为一组，每个像素组包括红R、绿G、蓝B、白W四种不同颜色的子像素。
S302，向每行的相邻的两个所述像素组中分别位于同一相对位置的两个子像素输入极性相反的信号，且向每个所述像素组中相邻的至少两个子像素输入极性相同的信号。
具体实现中，向每个所述像素组中的各子像素输入极性相同的信号。如图4A所示，对该行像素中相邻的两个像素组分别输入正正正正，负负负负(++++，----)的信号，如图4B所示，如果显示画面为红色图像，该行像素中相邻的两个像素组中的红色的子像素分别正极性和负极性，因此，该行的所有像素组的极性处于平衡状态。
可选的，向每个所述像素组中相邻的三个子像素输入极性相同的信号。如图5A所示，对该行像素中相邻的两个像素组分别输入正正正负，负负负正(+++-，---+)的信号，如图5B所示，如果显示画面为绿色及蓝色图像，该行像素中的一个像素组中的绿色子像素以及蓝色的子像素均显示正极性，与该像素组相邻的另一个像素组中的绿色子像素以及蓝色的子像素均显示负极性。因此，该行的所有像素组的极性处于平衡状态。
可选的，向每个所述像素组中相邻的二个子像素输入极性相同的信号。如图6A所示，对该行像素中相邻的两个像素组分别输入正正负负，负负正正(++--，--++)的信号，如图6B所示，如果显示画面为蓝色、白色及红色图像，该行像素中的一个像素组中的红色的子像素、白色的子像素及蓝色的子像素显示正正负，与该像素相邻的另一个像素组中的红色的子像素、白色的子像素及蓝色的子像素显示负负正。因此，该行的所有像素组的极性处于平衡状态。
在本发明实施中，在一帧的显示时间内，对每行的多个像素进行分组得到像素组，其中，所述多个像素中的每个像素包括四种不同颜色的子像素，所述像素组包括相邻的四种不同颜色的子像素；向每行的相邻的两个所述像素组中分别位于同一相对位置的两个子像素输入极性相反的信号，且向每个所述像素组中相邻的至少两个子像素输入极性相同的信号，这样在一帧的显示时间内，以像素组为基本单位对每行像素中各像素组所施加的信号整体上 可以达到极性平衡，从而像素中各颜色的子像素上施加的信号不再偏向某一极性，进而改善了显示单一颜色图案时由于单一颜色子像素上施加的正负极性信号不平衡而影响画面品质。
请参考图7，图7是本发明提出的一种四色显示器的驱动方法的第一实施例的流程图。如图所示，本发明实施例中的方法包括：
S701，对每行的多个像素进行分组得到像素组，其中，所述多个像素中的每个像素包括四种不同颜色的子像素，所述像素组包括相邻的四种不同颜色的子像素。
具体实现中，显示面板中各像素可以由四种颜色不同的子像素组成，每个像素呈阵列排列，各像素组包括相邻的四种不同颜色的子像素，例如：各像素分别包括红R、绿G、蓝B、白W四种不同颜色的子像素，将每行像素进行分组，以相邻的四个子像素为一组，每个像素组包括红R、绿G、蓝B、白W四种不同颜色的子像素。
S702，向每行的相邻的两个所述像素组中分别位于同一相对位置的两个子像素输入极性相反的信号，且向每个所述像素组中相邻的至少两个子像素输入极性相同的信号。
具体实现中，向每个所述像素组中的各子像素输入极性相同的信号。如图4A所示，对该行像素中相邻的两个像素组分别输入正正正正，负负负负(++++，----)的信号，如图4B所示，如果显示画面为红色图像，该行像素中相邻的两个像素组中的红色的子像素分别正极性和负极性，因此，该行的所有像素组的极性处于平衡状态。
可选的，向每个所述像素组中相邻的三个子像素输入极性相同的信号。如图5A所示，对该行像素中相邻的两个像素组分别输入正正正负，负负负正(+++-，---+)的信号，如图5B所示，如果显示画面为绿色及蓝色图像，该行像素中的一个像素组中的绿色子像素以及蓝色的子像素均显示正极性，与该像素组相邻的另一个像素组中的绿色子像素以及蓝色的子像素均 显示负极性。因此，该行的所有像素组的极性处于平衡状态。
可选的，向每个所述像素组中相邻的二个子像素输入极性相同的信号。如图6A所示，对该行像素中相邻的两个像素组分别输入正正负负，负负正正(++--，--++)的信号，如图6B所示，如果显示画面为蓝色、白色及红色图像，该行像素中的一个像素组中的红色的子像素、白色的子像素及蓝色的子像素显示正正负，与该像素相邻的另一个像素组中的红色的子像素、白色的子像素及蓝色的子像素显示负负正。因此，该行的所有像素组的极性处于平衡状态。
S703，向相邻行的两个所述像素组中分别位于同一相对位置的中的两个子像素输入极性相同的信号。
具体实现中，如图8A所示，在第一行的一个像素组中各个子像素中分别输入正正正正(++++)的信号，在第二行的与该像素组相邻的另一个像素组中的各个子像素中也分别输入正正正正(++++)的信号。如图8B所示，如果显示画面为红色图像，红色的子像素所在的列的极性分别为+-+-…，因此，在列方向上的像素组的极性达到平衡。如图8C所示，如果显示画面为红色和绿色图像，第一行中的第一个像素组中的红色的子像素以及绿色的子像素与第二行中的第一个像素组中的红色的子像素以及绿色的子像素均为正极性，第一行中的第二个像素组中的红色的子像素以及绿色的子像素与第二行中的第二个像素组中的红色的子像素以及绿色的子像素均为负极性，这样以此类推，该显示画面在列方向上的极性在整体上达到了平衡。
在本发明实施中，在一帧的显示时间内，对每行的多个像素进行分组得到像素组，其中，所述多个像素中的每个像素包括四种不同颜色的子像素，所述像素组包括相邻的四种不同颜色的子像素；向每行的相邻的两个所述像素组中分别位于同一相对位置的两个子像素输入极性相反的信号，且向每个所述像素组中相邻的至少两个子像素输入极性相同的信号，这样在一帧的显示时间内，以像素组为基本单位对每行像素中各像素组所施加的信号整体上可以达到极性平衡，从而像素中各颜色的子像素上施加的信号不再偏向某一 极性，进而改善了显示单一颜色图案时由于单一颜色子像素上施加的正负极性信号不平衡而影响画面品质。
请参考图9，图9是本发明实施例提出的一种四色显示器的驱动装置的结构示意图。如图所示，本发明实施例中的装置包括：

输入模块902，用于向每行的相邻的两个所述像素组中分别位于同一相对位置的两个子像素输入极性相反的信号，且向每个所述像素组中相邻的至少两个子像素输入极性相同的信号。
具体实现中，向每个所述像素组中的各子像素输入极性相同的信号。如图4A所示，对该行像素中相邻的两个像素组分别输入正正正正，负负负负(++++，----)的信号，如图4B所示，如果显示画面为红色图像，该行像素中相邻的两个像素组中的红色的子像素分别正极性和负极性，因此，该行的所有像素组的极性处于平衡状态。
可选的，向每个所述像素组中相邻的三个子像素输入极性相同的信号。如图5A所示，对该行像素中相邻的两个像素组分别输入正正正负，负负负正(+++-，---+)的信号，如图5B所示，如果显示画面为绿色及蓝色图像，该行像素中的一个像素组中的绿色子像素以及蓝色的子像素均显示正极性，与该像素组相邻的另一个像素组中的绿色子像素以及蓝色的子像素均显示负极性。因此，该行的所有像素组的极性处于平衡状态。
可选的，向每个所述像素组中相邻的二个子像素输入极性相同的信号。如图6A所示，对该行像素中相邻的两个像素组分别输入正正负负，负负正正(++--，--++)的信号，如图6B所示，如果显示画面为蓝色、白色及红色图像，该行像素中的一个像素组中的红色的子像素、白色的子像素及蓝色的子像素显示正正负，与该像素相邻的另一个像素组中的红色的子像素、白色的子像素及蓝色的子像素显示负负正。因此，该行的所有像素组的极性处于平衡状态。
