具体实施方式
为了便于理解本申请，下面将参照相关附图对本申请进行更全面的描述。附图中给出了本申请的较佳实施例。但是，本申请可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本申请的公开内容的理解更加透彻全面。
除非另有定义，本文所使用的所有的技术和科学术语与属于发明的技术领域的技术人员通常理解的含义相同。本文中在发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在限制本申请。本文所使用的术语“和/或”包括一个或多个相关的所列项目的任意的和所有的组合。
如图1所示，VA型液晶技术正视角及侧视角观察红色子像素R、绿色子像素G、蓝色子像素B灰阶亮度比例变化，其中纵坐标为亮度，横纵坐标为电压，可以发现侧视角蓝色子像素B亮度随电压增加，亮度饱和的趋势比红色子像素R和绿色子像素G来的显着及快速，使得混色视角观察画质会呈现偏蓝色偏的明显缺陷。
如图2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，图2中从左至右依次为蓝色子像素B、绿色子像素G和红色子像素R，以绿色子像素G为例，绿色子像素G分成主像素A和次像素B。然后再空间上给予主像素和次像素不同的驱动电压，图3为子像素未分主像素和次像素的曲线图，图4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。图5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5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。
图6为一实施例中的显示面板像素驱动方法的流程图。该显示面板像素 驱动方法可以改善液晶大视角折射率不匹配造成的色偏(或者色差)缺点。尤其是能够有效改善大视角蓝色子像素过早饱和造成色偏的缺陷。显示面板可以为TN(TwistedNematic，扭曲向列)、OCB(OpticallyCompensatedBirefringence，光学补偿弯曲排列)、VA(Vertical Alignment，垂直配向)型液晶显示面板以及曲面型液晶显示面板，但并不限于此。参见图6，该显示面板像素驱动方法用于显示面板的蓝色子像素驱动，该方法包括如下步骤：
S110：将显示面板上的像素单元划分为多个像素组。
在本实施例中，显示面板至少包括蓝色子像素，如图10所示，空间上显示面板全幅蓝色显示区划分为多个像素组n＝0，1，2…n…，m，分别标记为B1，B2，B3…Bn…Bm。如图11所示，每一个的像素组n内包含有多个蓝色子像素，其中一像素组n内的蓝色子像素排列Bn_1，1、Bn_1，2、…Bn_i，j。显示面板划分为多个像素组，像素组分的越多，驱动的时候将蓝色信号分成的份数也越多，显示的蓝色画面更好。像素组包括多个蓝色子像素，蓝色子像素越少，则蓝色的解析度越高，但是计算量也增加了，需要找到一个计算量合理解析度较高的值，如10*10个。在其他的实施例中，每个像素组中包括的像素个数可以根据需要进行设定。
S120：获取每个像素组的原始驱动数据，根据原始驱动数据得到每个像素组的显示色相。
显示色相是基于CIE LCH颜色空间系统并参考CIE规范的各色彩空间坐标的函数求取得到的。具体地，L＝f1(R、G、B)，C＝f2(R、G、B)，H＝f3(R、G、B)，其中，L表示亮度，C表示色彩纯度，代表颜色的鲜艳程度，H表示显示色相，也即颜色代表。上述函数关系根据CIE规范即可获知。CIE LCH颜色空间系统如图12所示。在CIE LCH颜色空间系统中，用0～360°代表不同色相颜色呈现。其中定义0°为红色，90°为黄色，180°为绿色，270°为蓝色。每个像素组的显示色相H可以通过该像素组的平均驱动电压来计算获取。
具体地，每个像素组均包括红色子像素、绿色子像素和蓝色子像素。因此，先求取每个像素组当前的各种颜色子像素的平均灰阶值R′n、G′n、B′n。
Bn′＝Average(Bn_1，1、Bn_1，2、…..Bn_2，1、Bn_2，2………、Bn_i，j)；
Rn′＝Average(Rn_1，1、Rn_1，2、…..Rn_2，1、Rn_2，2………、Rn_i，j)；
Gn′＝Average(Gn_1，1、Gn_1，2、…..Gn_2，1、Gn_2，2………、Gn_i，j)。
其中，n表示划分后的像素组的序号，(i，j)表示红色子像素、绿色子像素和蓝色子像素在整个像素组内的顺序编号。因此，将上述平均灰阶值R′n、G′n和B′n带入函数关系H＝f3(R、G、B)即可求取出对应像素组的显示色相：
H＝f3(R′n、G′n、B′n)。
在一实施例中，还会同时根据上述平均灰阶值求取每个像素组的色彩纯度C。色彩纯度C的范围表示在0到100，100代表色彩最为鲜艳。色彩纯度C的数值在一定程度表现了液晶显示装置件的显示驱动时的电压信号。将上述平均灰阶值R′n、G′n和B′n带入函数关系C＝f2(R、G、B)中，即可求取出对应像素组的色彩纯度：
C＝f2(R′n、G′n、B′n)。
S130：根据显示色相所属的色相范围获取灰阶值查找表。
在确定每个像素组的显示色相所属的色相范围之前，会预先将色相值划分为多个范围区域。每个范围区域可以根据需要改善的色偏程度来确定。在本实施例中，将色相值划分为6个区域：第一区，0°＜H≤45°和315°＜H≤360°；第二区，45°＜H≤135°；第三区，135°＜H≤205°；第四区，205°＜H≤245°；第五区，245°＜H≤295°；以及第六区，295°＜H≤315°。因此，根据求取得到的每个像素组的显示色相即可确定其所属的范围。可以理解，显示色相值的划分可以根据实际需要进行划分，并不限于此。
S140：灰阶值查找表中的每一个蓝色子像素的原始驱动数据对应一组目标灰阶值对，每组目标灰阶值对包括不相等的第一电压信号和第二电压信号， 使第一电压信号与第二电压信号交替驱动蓝色子像素的正视角混合亮度等效于原始驱动数据驱动蓝色子像素的正视角亮度。
灰阶值查找表中的每一蓝色子像素的灰阶值对应一组目标灰阶值对。每组目标灰阶值对包括不相等的第一电压信号和第二电压信号，该第一电压信号和第二电压信号需要满足，使得第一电压信号与第二电压信号交替驱动蓝色子像素的正视角混合亮度等效于原始驱动数据驱动蓝色子像素的正视角亮度。优选的，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。目标灰阶值对的获取可以通过查找灰阶值查找表(LUT)进行查找获取。
不同的色相值对视角色偏的影响不同，因此不同的色相范围对应不同的灰阶值查找表，从而使得对应于不同的色相范围能够获得更为适合该色相范围的目标灰阶值对，目标灰阶值对与驱动电压对应，也即通过更为合适的驱动电压来进行驱动，进而可以确保调节后的蓝色子像素在侧视下的亮度随灰阶变化更接近正视下的变化曲线。各色相范围与灰阶值查找表的对应关系表可以预先存储在存储部件内，因此根据查表获取到的灰阶信号即可确定对应的驱动电压。
例如，当显示色相所属的色相范围为第一区时采用灰阶值查找表LUT1，显示色相所属的色相范围为第二区时采用灰阶值查找表LUT2，如下表：
Figure PCTCN2017091641-appb-000001
Figure PCTCN2017091641-appb-000002
上述仅仅为一具体示例，色相范围的范围划分以及各色相范围与灰阶值查找表的对应关系并不限于上述实施例所限定的实现方式。
在另一实施例中，灰阶值查找表需要同时根据显示色相和色彩纯度所属的范围进行获取。具体地，不同的色相范围有不同的色彩纯度设定。对应于不同区的色彩纯度的范围设置也可以根据实际需要改善的色偏程度来决定。例如，色相范围第一区对应第一色彩纯度范围CTL1≤C≤CTH1；色相范围第二区对应第二色彩纯度范围CTL2≤C≤CTH2；色相范围第三区对应第三色彩纯度范围CTL3≤C≤CTH3；依次类推。因此，根据求取到的显示色相和色彩纯度可以确定其所属的范围。以本实施例为例，当显示色相H和色彩纯度C均满足以下两个条件时，即可确定其属于第一范围：
0°＜H≤45°或者315°＜H≤360°；
CTL1≤C≤CTH1。
当显示色相H和色彩纯度C均满足以下两个条件时，即可确定其属于第二范围：
45°＜H≤135°；
CTL2≤C≤CTH2。
因此，根据显示色相和色彩纯度所属的范围即可获取到对应的灰阶值查找表。
根据平均信号Bn′与Rn′、Gn′查表(LUT)获取蓝色子像素对应的第一电压信号和第二电压信号组合为Ln_i，j及Hn_i，j，即低电压信号和高电压信号组合。这样针对不同亮度的画质信号具有不同的平均值，查表后获取不同的 第一电压信号和第二电压信号组合，使蓝色子像素的gamma曲线更贴近目标gamma曲线。
S150：将每个像素组的蓝色子像素分成多组蓝色像素对，每组蓝色像素对包括相邻的第一蓝色子像素和第二蓝色子像素，相邻的蓝色像素对中的其中一组蓝色像素对的第一蓝色子像素和另外一组蓝色像素对的第二蓝色子像素相邻设置。
每个像素组内的蓝色子像素分成多组蓝色像素对，每组蓝色像素对包括相邻的第一蓝色子像素和第二蓝色子像素，其中第一蓝色子像素和第二蓝色子像素可以横向相邻也可以纵向相邻。相邻的蓝色像素对的第一蓝色子像素错开设置，即一组蓝色像素对的第一蓝色子像素与其他组蓝色像素对中的第二蓝色子像素相邻。
S160：根据第一蓝色子像素第一电压信号和多个相邻蓝色子像素的第一电压信号按不同权重获取第一亮度信号，根据第一亮度信号驱动第一蓝色子像素；根据第二蓝色子像素第二电压信号和多个相邻蓝色子像素的第二电压信号按不同权重获取第二亮度信号，根据第二亮度信号驱动第二蓝色子像素。
例如，第一电压信号为低电压信号，第二电压信号为高电压信号，第一蓝色子像素获取自身的低电压信号和相邻的低电压信号，然后按不同权重获取新的低电压信号即第一亮度信号，第二蓝色子像素同理获取新的高电压信号即第二亮度信号，然后分别用新的低电压信号和新的高电压信号驱动第一蓝色子像素和第二蓝色子像素，用一高一低亮度间隔信号取代原该位置的图像子像素信号，低的亮度信号可以起到改善视角色偏的作用。高的亮度信号维持显示解析度。在另一个实施例中，第一电压信号为高电压信号，第二电压信号为低电压信号。
在本实施例中，空间上原图全幅蓝色显示区分成为若干个像素组，用一高一低亮度间隔信号取代原该位置的图像子像素信号，较低的亮度信号可以起到改善视角色偏的作用。在保持较高穿透率设计情况下，使用不做低色偏补偿(Low color shift)的像素设计，人眼对于蓝色的分辨率感受较不敏锐， 空间上给予蓝色子像素一高一低亮度间隔信号，使得侧视角蓝色的亮度变化得到控制。改善了显示面板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。像素不再设计成主像素跟次像素，大大提升显示面板的穿透率，减少背光成本的设计，不会加大显示面板的工艺难度，不会影响产品良率，对于高分辨率显示面板提升穿透率及分辨率更为显著。
下面结合图7～图9对本实施例中的驱动方法的色偏改善效果做进一步说明。控制蓝色子像素B随电压增加亮度饱和的趋势接近红色子像素R、绿色子像素G，或者控制正视的红色子像素R、绿色子像素G、蓝色子像素B亮度饱和的趋势来减少视角色偏的严重缺陷。如图7所示，gamma4曲线为蓝色子像素电压增加随亮度变化曲线的目标曲线，通过蓝色子像素空间高低亮度信号间隔显示必须满足正看RGB亮度比例不变化，蓝色子像素空间高低亮度信号间隔显示的高电压信号与低电压信号有多种组合，每种组合造成的侧看亮度随电压变化饱和的情况不同。图7中蓝色子像素的第一组高电压信号与低电压信号组合的gamma曲线为gamma1曲线，第二组的gamma曲线为gamma2曲线从gamma1和gamma2曲线可以看到两种组合侧看亮度随电压变化饱和的情况不同。如图8所示，当考虑低电压与亮度变化关系时，第一组的gamma1曲线的实际亮度与目标亮度的差异为d1(n)，远大于第二组的gamma2曲线的实际亮度与目标亮度的差异值d2(n)。但是如图9所示，当考虑高电压与亮度变化关系时，第一组的gamma1曲线的实际亮度与目标亮度的差异为d1(n)，远小于第二组的gamma2曲线的差异值d2(n)。蓝色子像素空间高低亮度信号间隔显示的高电压与低电压组合为gamma1曲线时适合当画质内容上呈现蓝色较高亮度信号的时候，反之，蓝色子像素空间高低亮度信号间隔显示的高电压与低电压组合为gamma2曲线时适合当画质内容上呈现蓝色较低亮度信号的时候。
针对局部高电压、低电压及电压曲线在不同的组合设计上可以发现与目标gamma曲线会有不同的差异程度，一种蓝色子像素空间高低亮度信号间隔 显示的高电压与低电压组合无法同时满足高低电压亮度与目标亮度贴近的需求。
如图10所示，某一像素组n内的蓝色子像素为10*10的蓝色子像素范围，蓝色子像素为Bn_1，1、Bn_1，2、…Bn_10，10。为使得侧看蓝色子像素视角的gamma曲线更贴近正看的gamma曲线，不同蓝色子像素信号理论上可以给予时间上高低电压时序的循环切换获得正视跟侧视观察效果接近的高低电压组合，如表1的信号通过表2的低电压信号和表3的高电压信号按一定时序循环切换获得。第一电压信号小于原始信号，第二电压信号大于等于原始信号，可以通过时序循环切换获取等效或接近原始信号的亮度。

将如表1所示的原蓝色子像素信号Bn_i，j，以高低电压信号组合如表2与表3所示，依序呈现可以改善视角色偏。但是受限显示装置充电极限能力设计，低的图框扫描频率肉眼观察会看到严重的亮度闪烁现象。因此利用蓝色对人眼分辨率观察影响小的特点，将高低亮度信号组合Ln_i，j及Hn_i，j在空间上以牺牲分辨率方式交错排列显示如表4所示。在维持原图像图框频率显示的前提下，不需要面板硬件设计相应高帧率(high frame rate)的困难设计，并且不牺牲原图像分辨率太多得情况下，显示区域内的多个蓝色子像素予以高低亮度间隔信号取代原该位置的图像子像素信号来改善色偏。
以个别蓝色子像素为考虑，空间中若干个蓝色子像素为单位。该单位中蓝色子像素予以高低亮度间隔信号取代原该位置的图像蓝色子像素信号。如表4所示，空间中每5个蓝色子像素为一个单位。该单位中Bn_3，4以第一亮度信号即低亮度信号呈现，该低亮度信号可以起到改善视角色偏的作用。为维持像素分辨率的呈现，该单位中其他蓝色子像素即与Bn_3，4相邻的点(Bn_2，4、Bn_3，3、Bn_3，5、Bn_4，4)的第一电压信号即低电压信号分配给该单位中Bn_3，4的第一电压信号。
该单位中特定位置低亮度信号计算是统计该单位中理论上所有子像素需要给予低亮度信号补偿及该单位中个别子像素相应位置的真实位置影响性予以权重调整，使得该低亮度子像素信号得补偿效果可以符合该单位平均所需补偿信号的效果。

其中，根据第一蓝色子像素本身的第一电压信号和多个相邻蓝色子像素的第一电压信号按不同权重获取第一亮度信号。其中，第一蓝色子像素本身的第一电压信号的权重值为0.5，多个相邻蓝色子像素的第一电压信号的权重值为0.125。其中，多个相邻蓝色子像素的第一电压信号的权重值的和小于等于1。如表5所示，以5个蓝色子像素为一个单位，Bn_3，4为低亮度信号呈现的新的低亮度信号Ln′_3，4信号，该单位内所有低电压信号蓝色子像素Ln_i，j对于呈现低亮度信号Ln′_3，4信号的贡献权重如表6所示，该Ln′_3，4信号考虑了Ln_2，4、Ln_3，3、Ln_3，5、Ln_4，4及Ln_3，4五个蓝色子像素低电 压信号，其中Ln_3，4相应权重值为0.5，其余Ln_2，4、Ln_3，3、Ln_3，5、Ln_4，4四个蓝色子像素相应权重值为0.125。
在另一个实施例中，第一蓝色子像素的第一电压信号的权重值等于多个相邻与其蓝色子像素的第一电压信号的权重值的和。如表4中的边缘点会取得更好的权重值。

如表7所示，以5个蓝色子像素为一个单位，对应特定蓝色子像素位置Bn_2，4给予高亮度信号Hn′_2，4，为改善画质呈现的分辨率，该高亮度信号Hn′_2，4除了呈现本身的Hn_2，4高电压信号外还必须包括考虑相邻蓝色子像素Bn_1，4、Bn_2，3、Bn_2，5、Bn_3，4的高电压信号Hn_1，4、Hn_2，3、Hn_2，5、Hn_3，4，该四个蓝色子像素高电压信号可分配在相邻的可呈现高亮度信号的蓝色子像素上，如Bn_3，4的高电压信号Hn_3，4就可以分配信号给Hn_2，4、Hn_3，3、Hn_3，5和Hn_4，4对应的蓝色子像素。如此，相邻的蓝色子像素包括的四个蓝色子像素Bn_1，4、Bn_2，3、Bn_2，5、Bn_3，4呈十字形设置，且围绕Bn_2，4设置。还可以以9个蓝色子像素为一个单位，相邻的蓝色子像素包括的八个蓝色子像素Bn_1，3、Bn_1，4、Bn_1，5、Bn_2，3、Bn_2，5、Bn_3，3、Bn_3，4、Bn_3，5呈米字形设置，且围绕Bn_2，4设置。

如表7所示，以5个蓝色子像素为一个单位，以Bn_2，4位置为高亮度信号呈现新的高亮度显示信号Hn′_2，4信号，该区块n内所有蓝色子像素高电压信号Hn_i，j对于呈现新的高亮度显示信号Hn′_2，4信号的贡献权重如表8所示，该Hn′_2，4信号考虑了Hn_1，4、Hn_2，3、Hn_2，5、Hn_3，4及Hn_3，4 五个蓝色子像素高亮度信号，其中Hn_2，4相应权重值为0.5，其余Hn_1，4、Hn_2，3、Hn_2，5、Hn_3，4四个蓝色子像素相应权重值为0.125。
在另一个实施例中，第二蓝色子像素的第二电压信号的权重值等于多个与其相邻蓝色子像素的第二电压信号的权重值的和。如表4中的边缘点会取得更好的权重值。

因此，本实施方式中Bn_3，4位置给予得低灰阶亮度代表信号Ln′_3，4为Ln′_3，4＝0.5*Ln_3，4+0.125*(Ln_2，4+Ln_3，3+Ln_3，5+Ln_4，4)。
同理高亮度位置Bn_2，4亮度代表信号H′_24为Hn′_2，4＝0.5*Hn_2，4+0.125*(Hn_1，4+Hn_2，3+Hn_2，5+Hn_3，4)。
以此类推，每个高低电压亮度位置均可以等效出相同的结果，达到视角补偿同时又可以兼具图像分辨率的呈现。
