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， 所描述的实施例仅仅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。
下面结合下述附图对本发明实施例做详细描述。
本发明实施例提供一种液晶面板驱动方法， 所述液晶面板包括多个像素单 元、 栅极驱动单元和数据驱动单元且采用帧反转驱动方式显示图形， 所述帧反 转包括若干次子帧单元反转， 所述子帧单元包括所述液晶面板中的至少一个像 素单元， 所述子帧单元反转用于在所述栅极驱动单元的控制下通过数据驱动单 元对所述子帧单元的极性进行反转， 所述液晶面板中的每个像素单元在一次帧 反转过程完成后进行一次极性反转。
需要说明的是， 液晶面板通过驱动液晶分子排列变化来达到变化显示图像 的效果。 因此为避免长时间扭转液晶分子使得液晶分子劣化， 液晶面板通常使 用交变电压来驱动液晶分子。 作为液晶面板的一种驱动方式， 帧反转驱动方式 可具体描述为： 若前一帧液晶面板全部像素单元输出某一极性的数据， 在下一 帧液晶面板全部像素单元将输出相反极性的数据并顺次进行循环。 其中， 像素 单元的极性是指像素单元的像素电压相对于公共电极电压而言的极性， 包含有 正极性和负极性两种类型。 举例来说， 如图 1和图 2所示， 以包括四行四列像 素的液晶面板为例， 帧反转驱动方式可描述为： 在第一帧液晶面板全部像素单 元如图 1所示输出正极性的数据， 在第二帧液晶面板全部像素单元如图 2所示 输出负极性的数据， 在第三帧液晶面板全部像素单元如图 1所示输出正极性的 数据， 在第四帧液晶面板全部像素单元如图 2所示输出负极性的数据， ···， 依 次循环。
而作为本发明的一种具体实施方式， 以上述提及的液晶面板第一帧和第二 帧作为一个完整的帧反转过程为例进行描述， 在该帧反转过程中设置若干次子 帧单元反转。 为筒单明了的描述本发明实施例， 在此以该帧反转过程中设置有 两次子帧单元反转为例。 如图 3所示，液晶面板包括多个像素单元、 栅极驱动单 元和数据驱动单元且采用帧反转驱动方式显示图形， 液晶面板第一帧时刻的示 意图可参见图 3中 S101所示， 首先液晶面板在第一帧开始后的 t l时刻开始第 一次子帧单元反转， 其中第一次子帧单元反转用于在栅极驱动单元的控制下通 过数据驱动单元将液晶面板中至少一个像素单元的极性进行反转， 例如第一次 子帧单元反转的像素单元包括位于奇数行与奇数列相交位置处的像素单元以及 位于偶数行与偶数列相交位置处的像素单元， 而液晶面板中其余位置处像素单 元的极性保持不变， 此时第一次子帧单元反转完成后的液晶面板如图 3中 S102 所示。 然后在完成第一次子帧单元反转后， 液晶面板在第一帧开始后的 t 2时刻 开始第二次子帧单元反转， 其中第二次子帧单元反转用于在栅极驱动单元的控 制下通过数据驱动单元将液晶面板中至少一个像素单元的极性进行反转， 例如 第二次子帧单元反转的像素单元包括位于奇数行与偶数列相交位置处的像素单 元以及位于偶数行与奇数列相交位置处的像素单元， 而液晶面板中其余位置处 像素单元的极性保持不变， 此时第二次子帧单元反转完成后的液晶面板如图 3 中 S103所示。 通过第一次子帧单元反转以及第二次子帧单元反转后， 液晶面板 完成一次帧反转过程。 需要说明的是， 液晶面板中的每个像素单元在一次帧反 转过程完成后进行了一次极性的反转。
与现有技术帧反转驱动方式相比， 在本发明实施例的液晶面板的一个帧反 转过程中设置有若干次子帧单元反转， 子帧单元包括液晶面板中的至少一个像 素单元， 子帧单元反转包括反转子帧单元的极性， 因此本发明实施例液晶面板 像素是通过多次子帧单元反转而并不是在一个帧周期内一次性的将全部像素单 元反转， 降低了本发明实施例液晶面板发生闪烁以及数据串扰的可能性， 提高 了液晶面板的显示效果。
需要说明的是， 第一， 在上述具体实施方式中， 若将第一帧开始时刻定义 为 0时刻， 第二帧开始时刻定义为 T时刻， 那么本领域技术人员可以理解， 第 一次子帧单元反转时刻 t l以及第二次子帧单元反转时刻 t2应该满足： 0 < t l < t2 < T0 第二， 在上述具体实施方式中， 关于第一次子帧单元反转以及第二次子 帧单元反转过程中反转的像素单元的描述仅为示例性描述， 事实上， 上述实施 方式中的第一次子帧单元反转的像素单元以及第二次子帧单元反转的像素单元 有多种可能的情况， 例如： 第一次子帧单元反转包括位于奇数行与偶数列相交 位置处的像素单元以及位于偶数行与奇数列相交位置处的像素单元， 第二次子 帧单元反转包括位于奇数行与奇数列相交位置处的像素单元以及位于偶数行与 偶数列相交位置处的像素单元。 唯一确定的是， 无论第一次子帧单元反转包括 的像素单元以及第二次子帧单元反转包括的像素单元是采用了何种可能的情 况， 液晶面板的每个像素单元在一次帧反转过程完成后进行了一次极性的反转。
作为本发明的另一种可能， 本发明实施例提出另一种液晶面板驱动方法。 本实施例中液晶面板驱动方法的工作背景可参考上述实施例， 在此不再赘述。 不同的是， 在本具体实施例中， 在一次帧反转过程中设置有四次子帧单元反转。 同样以四行四列的液晶面板第一帧以及四行四列的液晶面板第二帧作为一次帧 反转过程， 首先液晶面板在第一帧时刻的示意图如图 4中 S111所示， 液晶面板 在第一帧开始后的 t l ' 时刻开始第一次子帧单元反转， 其中第一次子帧单元反 转将液晶面板中至少一个像素单元的极性进行反转， 例如第一次子帧单元反转 的像素单元包括位于奇数行与奇数列相交位置处的像素单元， 将第一次子帧单 元包括的像素单元极性进行反转， 而液晶面板中其余位置处像素单元的极性保 持不变， 此时第一次子帧单元反转完成后的液晶面板如图 4中 S 112所示； 然后 在完成第一子帧单元反转后， 液晶面板在第一帧开始后的 t 2' 时刻开始第二次 子帧单元反转， 其中第二次子帧单元反转将液晶面板中至少一个像素单元的极 性进行反转， 例如第二次子帧单元反转的像素单元包括位于偶数行与奇数列相 交位置处的像素单元， 将第二次子帧单元包括的像素单元极性进行反转， 而液 晶面板中其余位置处像素单元的极性保持不变， 此时第二次子帧单元反转完成 后的液晶面板如图 4中 S11 3所示； 然后在完成第二次子帧单元反转后， 液晶面 板在第一帧开始后的 t 3' 时刻开始第三次子帧单元反转， 其中第三次子帧单元 反转将液晶面板中至少一个像素单元的极性进行反转， 例如第三次子帧单元反 转的像素单元包括位于奇数行与偶数列相交位置处的像素单元， 将第三次子帧 单元包括的像素单元极性进行反转， 而液晶面板中其余位置处像素单元的极性 保持不变， 此时第三次子帧单元反转完成后的液晶面板如图 4中 S114所示； 然 后在完成第三次子帧单元反转后， 液晶面板在第一帧开始后的 t4' 时刻开始第 四次子帧单元反转， 其中第四次子帧单元反转将液晶面板中至少一个像素单元 的极性进行反转， 例如第四次子帧单元反转的像素单元包括位于偶数行与偶数 列相交位置处的像素单元， 将第四次子帧单元包括的像素单元极性进行反转， 而液晶面板中其余位置处像素单元的极性保持不变， 此时第四次子帧单元反转 完成后的液晶面板如图 4中 S115所示。 通过第一次子帧单元反转、 第二次子帧 单元反转、 第三次子帧单元反转以及第四次子帧单元反转， 液晶面板完成了一 次帧反转过程， 液晶面板中的每个像素单元在一次帧反转过程完成后均进行了 一次极性的反转。 其中， 分析可知， 在本具体实施方式中， 若将第一帧开始时 刻定义为 0时刻， 第二帧开始时刻定义为 τ时刻， 那么第一次子帧单元反转时 刻 t l' 、 第二次子帧单元反转时刻 t2' 、 第三次子帧单元反转时刻 t 3' 以及第 四次子帧单元反转时刻 t4' 应该满足： 0 < t l ' < tl' < t 3' < t4' T。 按照 如图 3中的液晶面板的极性反转方式中每一子帧单元反转所对应的子帧单元包 含的液晶面板的像素单元的连接方式可参考图 5所示的连接方式实施。
需要注意的是， 在一个帧反转过程完成后液晶面板中的每一个像素单元进 行一次极性反转。 而在具体实施的过程中， 无论设置多少次子帧单元反转以及 子帧单元包括哪些像素单元， 该实施过程均应当认为是本发明所包含的内容。
另外， 需要说明的一点是， 上述关于极性的描述是子帧单元包括的像素单 元的像素电压相对于公共电极电压而言的极性， 因此本领域技术人员可以理解 ,
Figure imgf000008_0001
性。
进一步的， 相邻的所述子帧单元反转时间间隔相同。 其中， 设置相邻的子 帧单元反转时间间隔相同是为了使驱动液晶面板的控制过程变得更加筒单， 因 此相邻的子帧单元反转时间间隔相同是一种较为优选的选择。
进一步的， 所述子帧单元包括的液晶面板的像素单元在同一行或同一列上 互不相邻。 需要说明的是， 子帧单元包括液晶面板中的至少一个像素单元， 若 子帧单元包含的像素单元在同一行或同一列上是相邻的， 相邻的像素单元在极 性反转时可能会相互影响， 导致闪烁以及数据串扰的情况发生， 因此， 子帧单 元包括的液晶面板的像素单元在同一行或同一列上互不相邻是一种较为优选的 选择。
进一步的， 所述子帧单元的极性是所述子帧单元包括的像素单元的像素电 压相对于公共电极电压的极性。
本发明实施例提供的液晶面板驱动方法， 通过在帧反转中设置若干次子帧 单元反转， 子帧单元包括液晶面板中的至少一个像素单元， 子帧单元反转包括 反转子帧单元的极性， 液晶面板中的每个像素单元在一次帧反转过程完成后进 行一次极性反转， 从而减少了液晶面板产生闪烁和串扰的情况， 提高了液晶面 板以及显示装置的显示效果。
进一步的， 作为本发明实施例的一种具体实施方式， 如图 5至图 7所示， 所述液晶面板中包括栅线 1、 数据线 2、 薄膜晶体管 3、 像素单元 4、 栅极驱动 单元 5、 数据驱动单元 6等， 每一像素单元 4连接一薄膜晶体管 3 , 其中， 第一 行栅线与第一行像素单元的奇数列薄膜晶体管相连， 最后一行栅线与最后一行 像素单元的偶数列薄膜晶体管相连， 其余行栅线与所在行像素单元的奇数列薄 膜晶体管相连且其余行栅线与相邻上一行像素单元的偶数列薄膜晶体管相连， 与奇数行栅线连接的像素单元为第一子帧单元， 与偶数行栅线连接的像素单元 为第二子帧单元。 帧反转包括第一子帧单元反转以及第二子帧单元反转。
举例来说， 以如图 5所示的液晶面板为例， 液晶面板的工作过程可以理解 为： 栅极驱动单元 5用于提供控制信号， 该控制信号通过栅线 1打开对应的薄 膜晶体管 3 , 然后数据驱动单元 6用于提供显示数据， 该显示数据通过数据线 2 传输给像素单元 4进行图像显示。 显示数据中包括数据信息以及数据的正负极 性信息。 为了更加筒便的理解本发明实施例， 在此不考虑数据信息的具体情况, 而只以数据的正负极性来进行描述。
需要说明的是， 由于液晶面板设计上的不同， 其中栅线、 数据线、 薄膜晶 体管以及像素单元的连接方式存在多种可能情况。 因此在对液晶面板进行子帧 驱动过程中， 不仅要考虑液晶面板的驱动时序， 还需要结合液晶面板中栅线、 数据线、 薄膜晶体管以及像素单元之间连接方式对驱动时序的影响， 结构连接 方式要与控制时序相对应以达到进行子帧驱动的目的。 而如图 5至图 7所述的 液晶面板的结构以及本实施例中相关的驱动时序的描述， 仅为了本领域技术人 员方便理解本发明实施例， 并不是对本发明的进一步限定。
具体的， 以包括四行栅线四列数据线的液晶面板为例， 如图 5所示， 首先 液晶面板进行第一帧图像的显示， 此时液晶面板中各像素单元 4中显示图像的 电荷极性均为正； 以帧反转驱动方式驱动液晶面板， 帧反转包括第一子帧单元 反转以及第二子帧单元反转， 其中， 第一子帧单元为与奇数行栅线连接的像素 单元， 第二子帧单元为与偶数行栅线连接的像素单元。 首先， 液晶面板在第一 帧开始后 t l时刻开始第一子帧单元反转， 结合如图 5所示的液晶面板， 其驱动 过程可描述为， 液晶面板在第一子帧单元反转过程中， 栅极驱动单元 5提供控 制信号，控制开启与奇数行栅线 1连接的薄膜晶体管 3 , 数据驱动单元 6提供负 极性的数据信息。 因此第一子帧单元接收该负极性的数据信息并发生极性反转， 而其余位置处的像素单元保持不变， 此时液晶面板如图 6所示。
然后， 液晶面板在第一帧开始后 t 2时刻开始第二子帧反转， 结合如图 6所 示的液晶面板， 其驱动过程可描述为， 液晶面板在第二子帧单元反转过程中， 栅极驱动单元 5提供控制信号， 控制开启与偶数行栅线 1连接的薄膜晶体管 3 , 数据驱动单元 6提供负极性的数据信息。 因此第二子帧单元接收负极性的数据 信息并发生极性反转， 而其余位置处的像素单元保持不变， 此时液晶面板如图 7 所示。 通过第一子帧单元反转以及第二子帧单元反转后， 液晶面板完成了一次 帧反转过程。
需要说明的是， 液晶面板中的每个像素单元在一次帧反转过程完成后进行 了一次极性的反转。 而本领域技术人员可以理解， 上述关于液晶面板的结构的 描述仅是为了更加容易的理解本发明实施例液晶面板驱动方法， 而并不是对本 发明的进一步限定， 事实上， 本发明实施例液晶面板的结构可由工作人员根据 实际需要进行调整， 在此不做赘述。
本发明实施例提供的液晶面板驱动方法， 通过在帧反转中设置若干次子帧 单元反转， 子帧单元包括液晶面板中的至少一个像素单元， 子帧单元反转包括 反转子帧单元的极性， 液晶面板中的每个像素单元在一次帧反转过程完成后进 行一次极性反转， 从而减少了液晶面板产生闪烁和串扰的情况， 提高了液晶面 板以及显示装置的显示效果。
另一方面， 本发明实施例还提供了一种液晶面板， 该液晶面板采用了上述 提及的液晶面板驱动方法， 其驱动方法可参照上述实施例中针对驱动方法的描 述， 采用所述驱动方法的液晶面板的结构可能有^艮多种， 其中采用所述帧反转 包括两个子帧单元反转的液晶面板时， 所述液晶面板包括栅线、 数据线、 薄膜 晶体管、 像素单元， 每一像素单元连接一薄膜晶体管， 第一行所述栅线与第一 行所述像素单元的奇数列所述薄膜晶体管相连， 最后一行所述栅线与最后一行 所述像素单元的偶数列所述薄膜晶体管相连， 其余行所述栅线与所在行所述像 素单元的奇数列所述薄膜晶体管相连且其余行所述栅线与相邻上一行所述像素 单元的偶数列所述薄膜晶体管相连。
本发明实施例提供的液晶面板， 其中在液晶面板驱动过程中通过在帧反转 中设置若干次子帧单元反转， 子帧单元包括液晶面板中的至少一个像素单元， 子帧单元反转包括反转子帧单元的极性， 液晶面板中的每个像素单元在一次帧 反转过程完成后进行一次极性反转， 从而减少了液晶面板产生闪烁和串扰的情 况， 提高了液晶面板以及显示装置的显示效果。
以上所述， 仅为本发明的具体实施方式， 但本发明的保护范围并不局限于 此， 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内， 可轻易想到 变化或替换， 都应涵盖在本发明的保护范围之内。 因此， 本发明的保护范围应 以所述权利要求的保护范围为准。
