Description

一种显示面板的驱动方法 技术领域
本发明涉及显示技术领域，尤其涉及一种显示面板的驱动方法。
背景技术
随着液晶显示技术的发展，手机等移动设备的显示面板的结构和功能越来越多元化，同时，人们对显示面板的需求也越来越苛刻，为了满足大众的需求，面板厂商也对面板的设计做出各种调整，为了提升面板的品质及可靠性，就要牺牲其它的性能。
例如，为了解决面板的直流残留所带来的残影和画面闪烁，现有技术中一般采用极性反转的方式驱动显示面板。常见的极性反转方式包括帧反转、点反转、行反转、列反转等，在现有的显示面板中通常采用的是点反转和行反转。然而，频繁的极性反转会造成显示面板的功耗增加，进而影响设备的待机时间。
故，有必要提供一种显示面板的驱动方法，以解决现有技术所存在的问题。
 技术问题
本发明的一个目的在于提供一种显示面板的驱动方法，其可以在保证显示面板的显示效果的同时降低其功耗。
技术解决方案
为解决上述问题，本发明的优选实施例提供了一种显示面板的驱动方法， 所述显示面板具有多条扫描线、多条数据线、及多条所述扫描线和多条所述数据线限定的多个像素单元，全部所述扫描线被划分为两个扫描线组；所述驱动方法包括：
在每帧的显示时间内，依次对第一个所述扫描线组和第二个所述扫描线组进行扫描，同时对与第一个所述扫描线组连接的像素单元和对与第二个所述扫描线组连接的像素单元加载极性相反的数据信号；
在每帧的显示时间内，对与所述第一扫描线组连接的像素单元和对与所述第二扫描线组连接的像素单元加载极性相反的数据信号，具体包括：在每帧的显示时间内，对各所述数据线加载极性反转一次的数据信号；
所述扫描线包括奇数行扫描线和偶数行扫描线，其中，第一个所述扫描线组包括全部所述奇数行扫描线，第二个所述扫描线组包括全部所述偶数行扫描线。
在本发明的显示面板的驱动方法中，在同一帧的显示时间内，相邻所述数据线加载的数据信号的极性相同。
在本发明的显示面板的驱动方法中，在同一帧的显示时间内，相邻所述数据线加载的数据信号的极性相反。
在本发明的显示面板的驱动方法中，在每帧的显示时间内，依次对第一个所述扫描线组和第二个所述扫描线组进行扫描，具体包括：
在每帧的显示时间内，依次对第一个所述扫描线组中的扫描线进行逐行扫描；
在每帧的显示时间内，依次对第二个所述扫描线组中的扫描线进行逐行扫描。
在本发明的显示面板的驱动方法中，每一所述像素单元均连接一条扫描和一条数据线。
 有益效果
相对于现有技术，本发明的有益效果是：通过将全部所述扫描线划分为两个扫描线组，并且在每帧的显示时间内，依次对第一个所述扫描线组和第二个所述扫描线组进行扫描，同时对与第一个所述扫描线组连接的像素单元和对与第二个所述扫描线组连接的像素单元加载极性相反的数据信号，从而实现了对显示面板的行反转驱动或点反转驱动的同时，保证低画面闪烁，并且大幅度降低功耗。
为让本发明的上述内容能更明显易懂，下文特举优选实施例，并配合所附图式，作详细说明如下：

 本发明的最佳实施方式
这里所公开的具体结构和功能细节仅仅是代表性的，并且是用于描述本发明的示例性实施例的目的。但是本发明可以通过许多替换形式来具体实现，并且不应当被解释成仅仅受限于这里所阐述的实施例。
在本发明的描述中，需要理解的是，术语'中心'、'横向'、'上'、'下'、'左'、'右'、'竖直'、'水平'、'顶'、'底'、'内'、'外'等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。此外，术语'第一'、'第二'仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有'第一'、'第二'的特征可以明示或者隐含地包括一个或者更多个该特征。在本发明的描述中，除非另有说明，'多个'的含义是两个或两个以上。另外，术语'包括'及其任何变形，意图在于覆盖不排他的包含。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语'安装'、'相连'、'连接'应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
这里所使用的术语仅仅是为了描述具体实施例而不意图限制示例性实施例。除非上下文明确地另有所指，否则这里所使用的单数形式'一个'、'一项'还意图包括复数。还应当理解的是，这里所使用的术语'包括'和 / 或'包含'规定所陈述的特征、整数、步骤、操作、单元和 / 或组件的存在，而不排除存在或添加一个或更多其他特征、整数、步骤、操作、单元、组件和 / 或其组合。
在图中，结构相似的单元是以相同标号表示。
图 1 为现有技术中 GOA 驱动电路中多个 GOA 驱动单元的框图示意图。如图所示，在每个 GOA 单元中，设置有信号输入模块、扫描信号输出模块以及级传信号输入输出端。相邻的两个 GOA 单元可以通过给定的级传信号，实现对显示面板各行像素单元的正向扫描和反向扫描，具体如图 2 和图 3 所示。
图 2 为现有技术中隔行扫描驱动的正向扫描示意图，图 3 为隔行扫描驱动的反向扫描示意图。 GOA 驱动电路分别设置在显示区域的左右两侧，且设置在左侧的部分 GOA 驱动电路用于驱动各奇数行像素单元，设置在右侧的部分 GOA 驱动电路用于驱动各偶数行像素单元。
实际扫描时，如图 3 所示，正向扫描时，由设置在左侧的第一个 GOA 驱动单元对第一行像素单元进行扫描驱动，下一个时序，由设置在右侧的第一个 GOA 单元对第二行像素单元进行扫描驱动，下一个时序，由设置在左侧的第二个 GOA 单元对第三行像素单元进行扫描驱动，下一个时序，由设置在右侧的第二个 GOA 单元对第四行像素单元进行扫描驱动，以此循环下去。反向扫描时，扫描过程类似于上述正向扫描的过程，参见图 3 ，在此不再赘述。
进一步的，容易理解，当以上述正反扫方法对显示面板进行驱动时，如果要实现行反转或点反转，则每条数据线需要在从奇数行换至偶数行，以及从偶数行换至奇数行时改变其传输的数据信号的极性，这对数据驱动芯片的消耗是非常大的。
需要说明的是，显示面板具有多条扫描线、多条数据线、及多条扫描线和多条数据线限定的多个像素单元，其中，每一像素单元均连接一条扫描和一条数据线。在本发明实施例中，先将全部扫描线划分为两个扫描线组；接着在每帧的显示时间内，依次对第一个扫描线组和第二个扫描线组进行扫描，同时对与第一个扫描线组连接的像素单元和对与第二个扫描线组连接的像素单元加载极性相反的数据信号。特别地，与同一描线组中的扫描线连接的像素单元的极性相同，以此减少数据信号的极性反转次数，从而降低功耗。下面将具体说明。
图 4 为本发明实施例提供的显示面板的驱动方法的流程示意图，如图所示，该驱动方法包括：
步骤 S301 ，将全部扫描线划分为两个扫描线组；
步骤 S302 ，在每帧的显示时间内，依次对第一个所述扫描线组和第二个所述扫描线组进行扫描，同时对与第一个所述扫描线组连接的像素单元和对与第二个所述扫描线组连接的像素单元加载极性相反的数据信号。
在步骤 S301 中，将全部扫描线划分为两个扫描线组，其中，第一个扫描线组包括全部奇数行扫描线，第二个扫描线组包括全部偶数行扫描线。
在步骤 S302 中，参阅图 5 ，图 5 为本发明优选实施例提供的显示面板的驱动方法的时序图。如图所示，在每帧的显示时间内，依次对第一个扫描线组和第二个扫描线组进行扫描。
其中，在每帧的显示时间内，依次对第一个扫描线组和第二个扫描线组进行扫描，具体包括：
在每帧的显示时间内，依次对第一个扫描线组中的扫描线进行逐行扫描；在每帧的显示时间内，依次对第二个扫描线组中的扫描线进行逐行扫描。
具体的，可先利用左侧的第一个 GOA 单元对第一行扫描线进行扫描驱动，下一个时序，利用设置在左侧的第二个 GOA 单元对第三行扫描线进行扫描驱动，下一个时序，利用设置在左侧的第三个 GOA 单元对第五行扫描线进行扫描驱动，依次类推，直至完成对所有奇数行扫描线的扫描驱动。随后，可利用右侧的第一个 GOA 单元对第二行扫描线进行扫描驱动，下一个时序，利用设置在左侧的第二个 GOA 单元对第四行扫描线进行扫描驱动，下一个时序，利用设置在左侧的第三个 GOA 单元对第六行扫描线进行扫描驱动，依次类推，直至完成对所有偶数行扫描线的扫描驱动。
需要说明的是，本发明同样可先对第二个扫描线组进行驱动，再对第一个扫描线组进行驱动。本发明旨在将与同一极性像素单元连接的扫描线先打开，进而避免数据线上施加的数据信号不断切换极性，造成功耗增加。
进一步的，对与第一个扫描线组连接的像素单元和对与第二个扫描线组连接的像素单元加载极性相反的数据信号。其中，对于行反转驱动方式，在同一帧的显示时间内，相邻数据线加载的数据信号的极性相同；对于点反转驱动方式，在同一帧的显示时间内，相邻数据线加载的数据信号的极性相反。在行反转驱动方式或点反转驱动方式中，在同一列像素单元中，相邻像素单元加载的数据信号的极性相反。
具体的，在每帧的显示时间内，对与第一扫描线组连接的像素单元和对与第二扫描线组连接的像素单元加载极性相反的数据信号，具体包括：在每帧的显示时间内，对各数据线加载极性反转一次的数据信号。
本优选实施例的显示面板的驱动方法通过将全部扫描线划分为两个扫描线组，并且在每帧的显示时间内，依次对第一个扫描线组和第二个所述扫描线组进行扫描，同时对与第一个扫描线组连接的像素单元和对与第二个扫描线组连接的像素单元加载极性相反的数据信号，从而实现了对显示面板的行反转驱动或点反转驱动的同时，保证低画面闪烁，并且大幅度降低功耗。
本发明还提供一种显示面板，其采用以上所述的驱动方法进行驱动，具体可参照以上描述，在此不做赘述。
本发明还提供一种显示装置，其包括以上所述显示面板，具体可参照以上描述，在此不做赘述。
本发明的显示面板、其驱动方法及显示装置通过将全部扫描线划分为两个扫描线组，并且在每帧的显示时间内，依次对第一个扫描线组和第二个所述扫描线组进行扫描，同时对与第一个扫描线组连接的像素单元和对与第二个扫描线组连接的像素单元加载极性相反的数据信号，从而实现了对显示面板的行反转驱动或点反转驱动的同时，保证低画面闪烁，并且大幅度降低功耗。
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。
