Description

液晶显示面板极性反转驱动方法、 驱动装置及显示装置 技术领域
本发明涉及液晶显示技术领域, 具体涉及一种液晶显示面板极性反转驱 动方法、 驱动装置及显示装置。 背景技术
薄月莫晶体管液晶显示器 ( Thin Film Transistor-Liquid Crystal Display, TFT-LCD ) 由于具有画面稳定、 图像逼真、 消除辐射、 节省空间以及节省能 耗等优点, 被广泛应用于电视、 手机、 显示器等电子产品中, 已占据了平面 显示领域的主导地位。
如图 1中所示的液晶显示器, 其主要包含: 液晶显示面板(LCD面板) 和液晶显示面板驱动装置, 该驱动装置包括源极驱动器(Source Driver ), 栅 极驱动器(Gate Driver ), 时序控制器( T-con )等组件; 发送到液晶显示器的 信号主要包括: R、 G、 B是图象显示信号, DE是使能信号, MCLK是时钟 信号, Vsync以及 Hsync分别是垂直同步信号和水平同步信号。 时序控制器 将图像数据信号(DATA )、 行起始信号(STH )、 行锁存信号(TP )和极性反 转信号( POL )发送到源极驱动器,将列起始信号( STV )、列时钟信号( CPV ) 与输出使能信号 (OE )发送到栅极驱动器, 从而使液晶显示面板显示图像。
液晶显示面板的基本显像单位是子像素, 该子像素在液晶显示面板结构 中具有电容效应, 只要在其两端施加足够驱动电压就会显示图像; 而施加在 电容两端的电压分别是共同电压和数据线电压。 因此, 如果施加在电容两端 上的电压不进行正负极性反转, 则显示图像的子像素被同一直流电压长期充 电, 将会在共同电极和像素电极间的液晶取向层以及液晶层长期积存一定电 荷量, 如图 2中所示, 这样会导致该子像素的显示不良: 严重的会导致液晶 极化而使该子像素的液晶失效,轻微的影响亦将使得液晶显示面板产生残像, 即显示会有一些底色存在, 且颜色对比也会下降。 因此, 驱动子像素的信号 电压每隔一段时间需正负极性反转, 目前通常的做法是奇数帧和偶数帧之间 交替做极性反转。
即使在液晶显示面板的子像素上交替施加正负极性反转的信号电压, 但 示面板的自身特性不好, 又或者客户系统提供的图像信号模式问题以及信号 不稳定等因素, 都会造成最终施加在液晶显示面板的子像素上的信号电压正 负对称性不好, 在长时间图像显示之后, 由于总体偏向某一极性, 通常会产 生上述的液晶极化或者残像问题。 发明内容

实施例一
本实施例中, 以每一帧为一个极性排布单元, N为偶数为例进行说明。 现有的液晶显示面板极性反转驱动中, 每一帧进行一次像素电压信号极 性反转, 现有技术中的液晶显示面板极性反转驱动装置如图 1 中所示, 对于 其中时序控制器输出的极性反转信号 POL, 以极性反转信号 POL— 1和性反转 信号— 2为例进行说明;如图 3中所示,极性反转信号 POL— 1为一周期性信号 且以行起始信号 STH为时间参考基准, 在时序上, 极性反转信号 POL— 1是 对应行起始信号 STH的每个周期反转一次; 极性反转信号 POL— 2为一周期 性信号且以行起始信号 STH为时间参考基准, 在时序上, 第二极性反转信号 POL— 2是对应行起始信号 STH的每两个周期反转一次; 此外, 按输入液晶显 示面板的控制信号的规格, 极性反转信号的高低电位转换必须在行起始信号 STH之后特定的时间范围内方为有效。
如表 1和表 2中所示, 在极性反转信号 POL— 1的控制下, 任意相邻的子 像素极性相反, 且任意相邻的两帧极性相反, 本实施例中, 所述的极性为相 对于公共电极电压的极性, 表 1以及表 2中, "+" 表示相对于共同电极电压 为正电压, "-" 表示相对于共同电极电压负电压。

或者液晶显示面板的 自身特性不好, 又或者客户系统提供的图像信号模式问题以及信号不稳定等 因素, 都会造成最终施加在液晶显示面板的子像素上的信号电压正负对称性 不好, 例如, 如表 3 中所示, 其总体极性为负。 这样, 在长时间图像显示之 后, 由于每个子像素的像素电压信号总体偏向某一极性。 对于图 4中所示的 单个子像素(以图示中带背景填充的子像素为例;), 表 4中示出了该单个子像 素的总体电压变化, 可以看出, 该单个子像素的总体极性为负, 这样会产生 液晶极化或者残像问题。 现有极性反转驱动方法中各帧极性表

根据本发明实施例所提供的液晶显示面板极性反转驱动方法, 在上述每 一帧正负极性交替反转驱动方法的基础上, 每 N帧, 进行一次每两帧正负极 性交替的反转驱动(下称 2帧反转), 如表 5中所示, 这样极性反转驱动周期 为 2N 帧, 每个半反转驱动周期中, 有且仅有一个相邻的两帧极性相同, 在 该半反转驱动周期的其他任意相邻的两帧极性相反, 并且在任意相邻的两个 半反转驱动周期中, 对应的各帧极性相反。 本实施例的极性反转驱动方法中各帧极性表

从表 5中可以明显看出, 每一帧的总体极性正负交替变化。 这样, 在长 时间图像显示中, 由于每个子像素的像素电压信号总体极性正负交替变换, 平均电压为 0, 不偏向某一极性。
如图 5中所示, N=4, 每 4帧进行一次 2帧反转; 对于图 5中所示的单 个子像素(以图示中带背景填充的子像素为例;), 表 6中示出了该单个子像素 的总体电压变化, 可以看出, 该单个子像素的总体平均电压为 0, 极性不偏 转向某一极性, 杜绝了电荷的积累, 因此避免了液晶在极性反转驱动中出现 液晶极化或者残像的问题。 图 5中所示的单个子像素的电压变化

为了降低在一帧中色度亮度干扰现象的影响, 本实施例中, 每帧中任意 相邻的两个子像素极性相反。 当然, 也可以有其他实施方式, 例如, 以 RGB 三个子像素为一个像素单元, 每帧中任意相邻的两个像素单元极性相反等。 实施例二 实施例一中的液晶显示面板极性反转驱动方法实现方式筒易,便于操作, 但是由于在每 N帧进行 2帧反转时, 整幅画面的极性变化和其他帧的极性变 化不一致, 从而产生亮暗变化, 在视觉上则表现为闪烁现象。 为了解决该问 题, 本实施例中以每行为一个极性排布单元, 每 N帧, 对该行进行一次 2帧 反转, 各行交错进行 2帧反转, 避免整幅画面同时变化。 例如, 如表 7中所 示, 为 N等于 1时每一帧中, 各行的极性变化; 各帧的极性排布如图 6中所 示; 从表 7以及图 6中可以看出, 第 1行在第 2帧进行 2帧反转, 第 2行在 第 3帧进行 2帧反转, 第 3行在第 4帧进行 2帧反转, 第 4行在第 5帧进行 2帧反转, 依次类推。 再例如, 当 N等于 4时, 第 1行可以在第 4帧进行 2 帧反转, 第 2行在第 8帧进行 2帧反转, 第 3行在第 12帧进行 2帧反转, 第 4行在第 16帧进行 2帧反转, 依次类推。 又例如, 如表 8中所示, 为 N等于 2时每一帧中, 各行的极性变化; 各帧的极性排布如图 Ί中所示; 从表 8以 及图 7中可以看出, 第 1行在第 2帧进行 2帧反转, 第 2行在第 4帧进行 2 帧反转, 第 3行在第 6帧进行 2帧反转, 第 4行在第 8帧进行 2帧反转, 依 次类推。 再例如, 当 N等于 4时, 第 1行可以在第 4帧进行 2帧反转, 第 2 行在第 8帧进行 2帧反转, 第 3行在第 12帧进行 2帧反转, 第 4行在第 16 帧进行 2帧反转, 依次类推。 本实施例中 N=l时极性反转驱动方法中各帧极性表

本实施例中, 在每个半反转驱动周期的起始帧第 X帧 (第 1帧) 中, 任 意相邻的两行的极性相反, 并且在每行中任意相邻的两个子像素极性相反, 这些都是为了降低在一帧中色度亮度干扰现象的影响。 当然, 在实际应用中, 也可以视需求调整各个极性反转单元的极性排布以及调整各个极性反转单元 划分形式。 实施例三
