为了使本公开的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本公开进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本公开,并不用于限定本公开。
如图1所示,VA型液晶驱动在大视角亮度随电压快速饱和,如附图1中L20曲线所示,造成视角画质对比及色偏相较于正视画质品质恶化严重,正视亮度随电压曲线如附图1中L10曲线所示。
在VA型液晶技术中,为了解决视角色偏,将RGB各子像素划分为主像素和 次像素,然后在空间上给予主像素和次像素不同的驱动电压,图2为子像素分主像素和次像素的曲线图,可以看出子像素分主像素和次像素可以有效解决视角色偏的缺陷。使得整体大视角亮度随电压变化较为接近正视,大视角亮度随电压如附图2中的L21曲线较为接近亮度随电压如附图2中L11曲面,其中L22、L23分别为主像素和次像素的曲线图。图3为RGB子像素液晶分子分别在低灰阶、中灰阶和高灰阶中像素分子的运动示意图,其中绿色子像素G液晶分子在中灰阶中主像素A和次像素B的运动如图3所示。但是这样的像素设计需要再设计金属走线或TFT组件来驱动次像素,从而造成可透光开口区牺牲,影响面板透率,直接造成背光成本的提升。
参见图4,显示面板的驱动方法包括以下步骤:
S110,将显示面板上的像素划分为多对像素组;每一对像素组包括相邻的第一像素组和第二像素组,第一像素组和第二像素组各包括第一子像素、第二子像素、第三子像素;
S120,根据画面输入信号查表获取对应每一个子像素不相等的第一电压信号和第二电压信号,以使第一电压信号与第二电压信号交替驱动子像素的正视角混合亮度,等效于画面输入信号驱动子像素的正视角亮度,其中画面输入信号包括相邻时序的第一画面和第二画面。
S130,分别用第一画面的第一像素组第一子像素的第一电压信号和第二电压信号,驱动所述第一画面的第一像素组和第二像素组的第一子像素;分别用第一画面的第二像素组第二子像素的第二电压信号和第一电压信号,驱动第一画面的第一像素组和第二像素组的第二子像素。
S140,分别用第二画面的第二像素组第一子像素的第二电压信号和第一电压信号,驱动第二画面的第一像素组和第二像素组的第一子像素;分别用第二 画面的第一像素组第二子像素的第一电压信号和第二电压信号,驱动第二画面的第一像素组和第二像素组的第二子像素。
在第一画面中,第一像素组和第二像素组的第一子像素分别获取一高一低的电压信号,第一像素组和第二像素组的第二子像素分别获取一低一高的电压信号,在第二画面中,第一像素组和第二像素组的第一子像素分别获取一低一高的电压信号,第一像素组和第二像素组的第二子像素分别获取一高一低的电压信号,可以在原画面输入信号频率呈现画面内容维持解析度又可以有色偏补偿效果,时序相邻的第一画面和第二画面代表解析度信号的子像素位置互换达到了更完善的解析度维持,保持完整图像解析度。其中第一子像素为红色子像素,第二子像素为绿色子像。其中第一子像素为红色子像素,第二子像素为绿色子像。RGB三原色子像素中由于红色子像素和绿色子像素的亮度信号较蓝色子像素的亮度信号更亮,红色子像素和绿色子像素会直接影响观赏图像解析度的呈现。因此,在第一画面中,第一像素组和第二像素组的红色子像素分别获取一高一低的电压信号,第一像素组和第二像素组的绿色子像素分别获取一低一高的电压信号,在第二画面中,第一像素组和第二像素组的红色子像素分别获取一低一高的电压信号,第一像素组和第二像素组的绿色子像素分别获取一高一低的电压信号,可以在原画面输入信号频率呈现画面内容维持解析度又可以有色偏补偿效果,时序相邻的第一画面和第二画面代表解析度信号的子像素位置互换达到了更完善的解析度维持,保持完整图像解析度。
其中步骤S120,根据画面输入信号按预设规则获取对应每一个子像素不相等的第一电压信号和第二电压信号,第一电压信号与第二电压信号交替驱动子像素的正视角混合亮度,等效于画面输入信号驱动子像素的正视角亮度,其中画面输入信号包括相邻时序的第一画面和第二画面。
具体的,其中画面输入信号包括相邻时序的第一画面和第二画面,如表1和表2所示。

R'5,1 G'5,1 B'5,1 R'5,2 G'5,2 B'5,2 R'5,3 G'5,3 B'5,3
进一步地,以RGB三原色显示面板为例,以红色子像素做说明,将红色子像素信号Ri,j分解成高电压RHi,j及低电压RLi,j图框并依序在相邻两个时序上显示高电压图框及低电压图框,高电压图框与低电压图框的合成效果等效于原图框各子像素亮度。高电压图框与低电压图框信号取代原始图框信号来达到正视亮度维持原图像信号亮度不变,侧视上视角透过时序上相邻两个时序上显示高电压图框及低电压图框,运用低电压图框视角特性相较于原图框亮度饱和现象可以改善进而使得视角色差获得改善。绿色子像素和蓝色子像素可以采用红色子像素相同的方法。
画面输入信号中的红色子像素R、绿色子像素G、蓝色子像素B一高一低的第一电压信号和第二电压信号为事先已经根据红色子像素R、绿色子像素G、蓝色子像素B输入信号给予的高低电压信号,是依照需要补偿的视角效果所决定, 一般是以查询表LUT的方式记录在显示面板里面,进一步地,查询表LUT记录在显示面板的硬体frame buffer里面,以8bit驱动信号来看每,一红色子像素R、绿色子像素G和蓝色子像素B输入信号输入0~255共对应256高低电压信号,共有3*256对高电压信号RH、GH、BH与低电压信号RL、GL、BL。其中蓝色子像素的查询表如表3所示。
表3:
Figure PCTCN2017102460-appb-000001
可选地,根据画面输入信号查表获取对应每一个子像素的第一电压信号和第二电压信号。其中第一电压信号与第二电压信号的正视角混合亮度,等效于画面输入信号正视角亮度。根据不同情况可以选取不同的查询表,如一对像素组的原始输入灰阶值的平均值、多对像素组的原始输入灰阶值的平均值等,查询表根据需要可以设置多个查询表,如2个、5个、10个等。同理,红色子像素和绿色子像素也可以设置多个查询表。
进一步地,第一电压信号与第二电压信号对应的大视角亮度与原始驱动数据的正视角亮度尽可能接近。在一实施例中,第一电压信号和第二电压信号之 间的差值需要大于预设的差值范围,从而确保目标灰阶值对中的两个灰阶值有较大的灰阶差。在本实施例中,大视角可以定义为大于60°,或者根据用户进行自定义。
例如,第一电压信号大于第二电压信号。
在一个实施例中,可选地,如表1所示,在第一画面中,第一像素组为R1,1、G1,1、B1,1,第二像素组为R2,1、G2,1、B2,1。如表4所示,在第一画面中,第一像素组的红色子像素R1,1用第一像素组红色子像素的第一电压信号驱动RH1,1,第二像素组的红色子像素R2,1用第一像素组红色子像素的第二电压信号驱动RL1,1。第一像素组的绿色子像素G1,1用第二像素组绿色子像素的第二电压信号驱动GL2,1,第二像素组的绿色子像素G2,1用第二像素组绿色子像素的第一电压信号GH2,1驱动。
如表2所示,在第二画面中,第一像素组为R'1,1、G'1,1、B'1,1,第二像素组为R'2,1、G'2,1、B'2,1。如表5所示,在第二画面中,第一像素组的红色子像素R1,1用第二像素组红色子像素的第二电压信号驱动RL'2,1,第二像素组的红色子像素R2,1用第二像素组红色子像素的第一电压信号驱动RH'2,1。第一像素组的绿色子像素G1,1用第一像素组绿色子像素的第一电压信号驱动G H'1,1,第二像素组的绿色子像素G2,1用第一像素组绿色子像素的第二电压信号G L'1,1驱动。

RH'4,1 GL'3,1 BH'4,1 RL'3,2 GH'4,2 BL'3,2 RH'4,3 GL'3,3 BH'4,3
RL'6,1 GH'5,1 BL'6,1 RH'5,2 GL'6,2 BH'5,2 RL'6,3 GH'5,3 BL'6,3
如此,在第一画面中,保留了第一像素组的红色子像素R1,1信号,牺牲了第二像素组的红色子像素R2,1信号。进一步地,将第一像素组红色子像素位置取代为查表后高电压信号即第一电压信号RH1,1,可以维持原图像解析度。牺牲的第二像素组红色子像素位置取代为查表后低电压信号即第二电压信号RL1,1,可以起到色偏改善得补偿效果。在第二画面中,保留了第二像素组的红色子像素R'2,1信号,牺牲了第一像素组的红色子像素R'1,1信号。进一步地,将第二像素组红色子像素位置取代为查表后高电压信号即第一电压信号R'H2,1,可以维持原图像解析度。牺牲的第一像素组红色子像素位置取代为查表后低电压信号即第二电压信号R'L2,1,可以起到色偏改善得补偿效果。
同理,在第一画面中,保留了第二像素组的绿色子像素G2,1信号,牺牲了第一像素组的绿色子像素G1,1信号。进一步地,将第二像素组绿色子像素位置取代为查表后高电压信号即第一电压信号GH2,1,可以维持原图像解析度。牺牲的第一像素组绿色子像素位置取代为查表后低电压信号即第二电压信号GL2,1,可以起到色偏改善得补偿效果。在第二画面中,保留了第一像素组的绿色子像素G'1,1信号,牺牲了第二像素组的绿色子像素G'2,1信号。进一步地,将第一像素组绿色子像素位置取代为查表后高电压信号即第一电压信号G'H1,1,可以维持原图像解析度。牺牲的第二像素组绿色子像素位置取代为查表后低电压信号即第二电压信号G'L1,1,可以起到色偏改善得补偿效果。
这样的画面分布虽然第一画面和第二画面各自牺牲了原画面一半的信号,但是由相邻位置在时序上原画面输入信号的依序呈现使得空间上等效看到分辨率的效果并没有牺牲。可以在原画面输入信号频率呈现画面内容的时候维持解析度,又可以有色偏补偿效果,无需透过增加扫描频率来增加画面内容来维持原画面解析度并且有色偏改善得效果。相邻两画面代表解析度信号的子像素位置互换达到了更完善的解析度维持,保持完整图像解析度。改善液晶大视角折射率不匹配造成的色差缺点,尤其应用于TN,OCB,VA型液晶显示面板,工艺简单,生产良率高。
其中,蓝色子像素主要扮演颜色呈现与观赏图像解析度的呈现影响并不大,相邻的第一像素组与第二像素组的蓝色子像素,如表1中的B1,1、B2,1,可以以其中一个子像素为主要图像解析度代表信号呈现。
可选地,第一画面的第一像素组和第二像素组的蓝色子像素如表1中的B1,1、B2,1,分别用第一画面的第一像素组蓝色子像素的第一电压信号和第二电压信号驱动,如表4中BH1,1、BL1,1;第二画面的第一像素组和第二像素组的蓝色子像素如表2中B'1,1、B'2,1,分别用第二画面的第二像素组蓝色子像素的第二电压信号和第一电压信号驱动,如表5中BL'2,1、BH'2,1。蓝色子像素跟随红色子像素变化,适用于绿色子像素亮度更亮的显示面板,还适用于红绿蓝排列的显示面板。

可选地,蓝色子像素还可以使用原画面输入信号驱动。
在一实施例中,第一像素组和第二像素组可以在相同列且相邻设置,即纵向相邻设置。如表1中第一像素组为R1,1、G1,1、B1,1,第二像素组为R2,1、G2,1、B2,1。如表4所示,在第一画面中,第一像素组的红色子像素R1,1用第一像素组红色子像素的第一电压信号RH1,1驱动,第二像素组的红色子像素R2,1用第一像素组红色子像素的第二电压信号RL1,1驱动。第一像素组的绿色子像素G1,1用第二像素组绿色子像素的第二电压信号GL2,1驱动,第二像素组的绿色子像素G2,1用第二像素组绿色子像素的第一电压信号GH2,1驱动。进一步地,相邻的两对像素组中的其中一对像素组中的第一像素组和另外一对像素组的第二像素组相邻设置,即相邻的两对像素组中的第一像素组错开设置。横向相邻的两对像素组中其中一对第一像素组在第二像素组上方,另一对像素组的第一像素组在第二像素组下方。用于实现相邻的像素组的第一像素组错开设置。
