具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
应当理解，当在本说明书和所附权利要求书中使用时，术语“包括”和 “包含”指示所描述特征、整体、步骤、操作、元素和/或组件的存在，但并不排除一个或多个其它特征、整体、步骤、操作、元素、组件和/或其集合的存在或添加。
参见图1，其为本申请实施例一提供的一种显示方法的示意流程图，如图所示，该方法包括以下步骤S11~S14：
步骤S11：接收目标画面的图像数据。
具体地，接收目标画面的图像数据，具体为显示装置的屏驱动板接收前端发送的待显示画面的图像数据，因为显示装置显示画面是一帧一帧的显示，因此屏驱动板接收前端数据也是一帧一帧地接收图像数据，将其中1~2帧图像数据存储在屏驱动板的存储器中，方便屏驱动板的控制IC对该1~2帧图像数据进行分析处理，以便执行后续步骤。
步骤S12：获取图像数据对应像素单元的红色、绿色、蓝色子像素单元对应的电压信号作为第一电压信号。
具体地，获取像素单元的红色、绿色、蓝色子像素单元对应的电压信号作为第一电压信号，即为，获取对应驱动每个红色、绿色、蓝色子像素单元进行显示目标画面的电压信号，将此电压信号作为第一电压信号供后续步骤进行转换。
步骤S13：将相邻的多个蓝色或绿色或红色子像素单元对应的电压信号组转换为电压高低相间分布的电压信号组，电压高低相间分布的电压信号组为第二电压信号。
具体地，参见图6至图8，其为电压（横轴）增加与亮度（纵轴）变化的曲线，K1为正看时目标电压增加随亮度变化曲线，通过相间分布的高低电压信号（即高低电压信号间隔分布，相邻的两个电压信号为一高一低）来满足正看和侧看的亮度变化的比例接近，相间分布的高电压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的情况不同，如图6所示，曲线K2与K4为两个高电压与低电压组合的侧看亮度随电压变化的情况，参见图7和图8，针对局部高电压及低电压曲线在不同的组合设计上可以发现与目标曲线K1会有不同的差异程度，一种相间分布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。
参见图7所示，当考量低电压与亮度变化关系时，相间分布的高电压与低电压组合K4，实际亮度与目标亮度的差异为d1(n)，远大于当空间分割的高电压与低电压组合K2, 实际亮度与目标亮度的差异为d2(n)。参见图8所示，当考量高电压与亮度变化关系时，相间分布的高电压与低电压组合为K4，实际亮度与目标亮度的差异为d1(n)，远小于相间分布的高电压与低电压组合K2。空间分割的高电压与低电压组合为K4适合当画质内容上呈现较高电压信号的时候，反之，空间分割的高电压与低电压组合为K2适合当画质内容上呈现较低电压信号的时候。运用如K4加上K2的高低电压组合产生的视角亮度曲线为K3,其特征结合了K4高灰阶组合及K2低灰阶组合的优势，让视角曲线更贴近目标曲线，曲线变化较为平滑，不容易有画质颜色突变或混色异常的现象发生。
具体地，以RGB三基色显示装置为例，每个像素单元对应有红绿蓝（RGB）三基色的子像素单元，与之对应的图像电压信号标记为Ri，j，Gi，j，Bi，j( i，j=1，2，3…)，下面以蓝色子像素单元的电压信号为例，取Bi，j以及相邻的Bi，j+1，Bi+1，j，Bi+1，j+1的四个电压信号，将这四个电压信号转换成 Bn’_H1， Bn’_H2高电压信号以及Bn’_L1，Bn’_L2低电压信号，其中Bn’_H1，Bn’_L1为一组电压组合如图6的K4曲线，Bn’_H2，Bn’_L2为另一组电压组合如图3的K2曲线，本申请将Bn’_H1，Bn’_H2，Bn’_L1，Bn’_L2 取代原先的Bi，j，Bi，j+1， Bi+1，j，Bi+1，j+1 四个蓝色子像素单元的画质信号，使得视角特性附图6中K3曲线相较于原来的K4，K2曲线，在高低灰阶都可以有较接近目标视角曲线K1的特点，解决一组电压无法同时解决高低电压可以同时满足视角补偿的缺点。等效查寻值Bn’_H1， Bn’_H2，Bn’_L1， Bn’_L2依据图12的判断方式进行置换。同理查寻值Gn’_H1，Gn’_H2，Gn’_L1，Gn’_L2判断方式亦相同。
参见图4和图5，以RGB三基色显示装置为例，将全幅蓝色画质的原图分割为多个区块 n=0，1，2，…，M，如图4所示，分别为B1、B2、B3、…、BM。如图5所示，每一个分割的区块n 内包含有多个蓝色子像素，蓝色子像素排列为Bn_1，1，Bn_1，2，…Bn_i，j。对n区块内所有的蓝色子像素信号取平均值得Bn’=Average(Bn_1，1， Bn_1，2，….. Bn_2，1， Bn_2，2………， Bn_i，j)。
同理，为全幅绿色画质的原图时，n区块内所有的绿色子像素信号取平均值得Gn’=Average(Gn_1，1， Gn_1，2，….. Gn_2，1， Gn_2，2………， Gn_i，j)。为全幅红色画质的原图时，n区块内所有的红色子像素信号取平均值得Rn’=Average(Rn_1，1， Rn_1，2，….. Rn_2，1， Rn_2，2………， Rn_i，j)。
本申请实施例通过颜色来判断RGB子像素单元的高低电压信号组合方式，参见图9所示的CIE LCH色彩空间图，计算在色座标系统中RGB的组合像素的颜色代表：L(亮度)、C(饱和度)、H(色相)。其中，H由0°~360°代表不同色相的颜色，定义0°为红色，90°为黄色，180°为绿色，270°为蓝色，C为色彩饱和度，代表颜色的鲜艳程度，C的范围表示为0到100，100代表色彩最为鲜艳，C的数值一定程度上体现了LCD显示电压信号的高低。
依据图12中具体的情况对RGB子像素单元对应的第一电压信号进行转换，得到相应的第二电压信号：
（1）、依照平均信号Bn’与Rn’，Gn’计算组合像素的色相满足 0°＜H≦45°和315°＜H≦360°，且色彩饱和度满足CTL1 ≦C≦ CTH2的判断标准的，采用高低电压组合R_LUT_1、G_LUT_1及B_LUT_1。
（2）、依照平均信号Bn’与Rn’，Gn’计算组合像素的色相满足 45°＜H≦135°且色饱和度满足CTL3 ≦C≦ CTH4的判断标准的，采用高低电压组合R_LUT_2、G_LUT_2及B_LUT_2。
（3）、依照平均信号Bn’与Rn’，Gn’计算组合像素的色相满足 135°＜H≦205°且色饱和度满足CTL5 ≦C≦ CTH6的判断标准的，采用高低电压组合R_LUT_3、G_LUT_3及B_LUT_3。
（4）、依照平均信号Bn’与Rn’，Gn’计算组合像素的色相满足 205°＜H≦245°且色饱和度CTL7 ≦C≦ CTH8的判断标准的，采用高低电压组合R_LUT_4、G_LUT_4及B_LUT_4。
（5）、依照平均信号Bn’与Rn’，Gn’计算组合像素的色相满足 2450＜H≦2950且色饱和度CTL9 ≦C≦ CTH10的判断标准的，采用高低电压组合R_LUT_5、G_LUT_5及B_LUT_5。
（6）、依照平均信号Bn’与Rn’，Gn’计算组合像素的色相满足 295°＜H≦315°且色饱和度CTL11 ≦C≦ CTH12的判断标准的，采用高低电压组合R_LUT_6、G_LUT_6及B_LUT_6。
每个平均信号Bn’与Rn’，Gn’对应固定R/G/B像素Rn_s_i，j，Rn_s_i，j+1， Rn_s_i+1，j，Rn_s_i+1，j+1 /Gn_s_i，j， Gn_s_i，j+1， Gn_s_i+1，j， Gn_s_i+1，j+1/Bn_s_i，j，Bn_s_i，j+1，Bn_s_i+1，j，Bn_s_i+1，j+1的两组高低电压组合Rn_s_H1，Rn_s_L1，Rn_s_H2，Rn_s_L2/Gn_s_H1，Gn_s_L1，Gn_s_H2，Gn_s_L2/Bn_s_H1，Bn_s_L1，Bn_s__H2，Bn_s__L2的查寻值，可以使得视角曲线更贴近目标曲线。
举例蓝色子像素单元信号，该分区n区块内，相邻四个子像素标记为Bn_s_i，j，Bn_s_i，j+1，Bn_s_i+1，j，Bn_s_i+1，j+1四个信号，取平均信号B’n_s=Average(Bn_s_i，j，Bn_s_i，j+1，Bn_s_i+1，j，Bn_s_i+1，j+1)，s代表n区块内各个以四个蓝色子像素单元为组合的小区块编号。该小区块内的新的蓝色子像素信号，由该小区块四个蓝色子像素信号取平均值信号B’n_s依据由n区块（Frame N）内的所有蓝色子像素单元的信号 Bn_i，j取平均信号Bn’依据颜色判断条件取的查表值来获得。查图12得出每组小区块信号平均值B’n_s的两组高低电压组合Bn_s_H1，Bn_s_L1以及Bn_s_H2，Bn_s_L2。该两组高低电压组合Bn_s_H1，Bn_s_L1以及Bn_s_H2，Bn_s_L 2信号与FrameN+1图框对应，即为对应新的小区块信号四个蓝色子像素单元的高低电压信号Bn_s_i，j= Bn_s_H1，Bn_s_i，j+1=Bn_s_L1，Bn_s_i+1，j=Bn_s_L2，Bn_s_i+1，j+1=Bn_s_H2。
步骤S14：驱动像素单元根据第二电压信号进行响应并显示目标画面。
具体地，驱动像素单元的RGB子像素单元根据转换而来的电压高低相间分布的第二电压信号进行响应并显示目标画面。
具体地，通过在获取图像数据对应的第一电压信号后，将第一电压信号转换为电压高低相间分布的第二电压信号，再由显示装置驱动像素单元根据第二电压信号进行响应并显示目标画面，让相邻空间上相间分布的高低电压信号来达成正视跟侧视亮度变化接近的目标，从而改善了色差现象。因为第二电压信号由每个独立的子像素单元进行响应，无需在RGB子像素单元上再进行划分主次像素，如此就避免再设计金属走线或TFT元件来驱动次像素而造成的可透光开口区减少，从而提高了面板光透率，降低了背光成本。
参见图2，是本申请实施例二提供的一种显示方法的示意流程图，如图所示，该方法包括以下步骤S21~S24：
步骤S21：接收目标画面的图像数据。
具体地，接收目标画面的图像数据，具体为显示装置的屏驱动板接收前端发送的待显示画面的图像数据，因为显示装置显示画面是一帧一帧的显示，因此屏驱动板接收前端数据也是一帧一帧地接收图像数据，将其中1~2帧图像数据存储在屏驱动板的存储器中，方便屏驱动板的控制IC对该1~2帧图像数据进行分析处理，以便执行后续步骤。
步骤S22：获取图像数据对应像素单元的红色、绿色、蓝色子像素单元对应的电压信号作为第一电压信号。
具体地，获取像素单元的红色、绿色、蓝色子像素单元对应的电压信号作为第一电压信号，即为，获取对应驱动每个红色、绿色、蓝色子像素单元进行显示目标画面的电压信号，将此电压信号作为第一电压信号供后续步骤进行转换。
步骤S23：将相邻的多个蓝色或绿色或红色子像素单元对应的电压信号组转换为电压高低相间分布的电压信号组，电压高低相间分布的电压信号组为第二电压信号。用于转换成每个第二电压信号的蓝色子像素单元的个数多于用于转换成每个第二电压信号绿色或红色子像素单元的个数。
具体地，红色和绿色采取比蓝色少（例如红色和绿色2个，蓝色4个）的子像素单元来作为为一组高低电压信号的转换，即用比蓝色子像素单元少的绿色或红色子像素单元作为一组进行转换，转换后的每个单独的高低电压信号组中绿色或红色子像素单元少于每个单独的高低电压信号组中的蓝色子像素单元。
依据图13中具体的情况对绿色和红色子像素单元对应的第一电压信号进行转换，得到相应的第二电压信号。
举例Red画素信号，该分区n区块内，相邻四个子像素Rn_s_i,j, Rn_s_i,j+1, Rn_s_i+1,j,Rn_s_i+1,j+1四个信号取平均信号：
R’n_s=Average(Rn_s_i,j,Rn_s_i,j+1),R’n_s+1=Average(Rn_s_i+1,j,Rn_s_i+1,j+1)。
s代表区块内各个以4个红色子像素为组合的小区块编号。S,S+1即把4 个红色子像素为组合的小区块编号再分割成两个独立决定高低电压信号对的组合。每个新的红色子像素信号，便由该4个子像素小区块再分成两个独立子像素信号平均值R’n_s、R’n_s+1依据由n区块（Frame N）内的所有蓝色子像素单元的信号 Bn_i，j取平均信号Bn’依据颜色判断条件取的查表值来对应输出则为对应新的小区块信号四个红色子像素单元如图13：Rn_s_i，j=Rn_s_H1，Rn_s_i，j+1=Rn_s_L1，Rn_s_i+1，j=Rn_s_L2，Rn_s_i+1，j+1=Rn_s_H2。
绿色子像素单元的转换方式与本实施例中红色子像素单元的转换相同，蓝色子像素单元的转换方式与上述实施例一中相同。
步骤S24：驱动像素单元根据第二电压信号进行响应并显示目标画面。
具体地，驱动像素单元的RGB子像素单元根据转换而来的电压高低相间分布的第二电压信号进行响应并显示目标画面。
具体地，因为人眼感受绿色和红色比较敏锐，由于转换成每个第二电压信号的蓝色子像素单元的个数多于用于转换成每个第二电压信号绿色或红色子像素单元的个数，使得转换后的绿色和红色的第二电压信号的解析度会高于蓝色的第二电压信号的解析度，从而避免了画面的颗粒感。
参见图3，是本申请实施例三提供的一种显示方法的示意流程图，如图所示，该方法包括以下步骤S31~S36：
步骤S31：接收目标画面的图像数据。
具体地，接收目标画面的图像数据，具体为显示装置的屏驱动板接收前端发送的待显示画面的图像数据，因为显示装置显示画面是一帧一帧的显示，因此屏驱动板接收前端数据也是一帧一帧地接收图像数据，将其中1~2帧图像数据存储在屏驱动板的存储器中，方便屏驱动板的控制IC对该1~2帧图像数据进行分析处理，以便执行后续步骤。
步骤S32：获取图像数据对应的第一电压信号。
具体地，获取图像数据对应的第一电压信号，即为，获取对应驱动每个像素单元进行显示目标画面的电压信号。
步骤S33：将相邻的第一电压信号转换为电压高低相间分布的第二电压信号。
具体地，将相邻的第一电压信号转换为电压高低相间分布的第二电压信号，具体转换方式参见实施例一或实施例二。
步骤S34：判断第二电压信号是否超过预设电压阈值。
具体地，将第二电压信号对应的电压大小与预设电压阈值的大小进行比较，判断第二电压信号对应的电压大小是否大于预设电压阈值。
步骤S35：若超过，根据预设删减比例对第二电压信号对应的持续时长进行删减。
具体地，如果第二电压信号对应的电压大小超过了预设电压阈值，则根据预先设定的删减比例将超过预设电压阈值的第二电压信号对应的持续时长进行删减，例如，预设的删减比例为20%，超过预设电压阈值的第二电压信号对应的持续时长为100ms，则根据删减比例20%将原先的100ms减去20ms，最终超过预设电压阈值的第二电压信号对应的持续时长为80ms。
步骤S36：驱动像素单元根据第二电压信号进行响应以显示目标画面。
具体地，驱动像素单元的RGB子像素单元根据转换而来的电压高低相间分布的第二电压信号进行响应并显示目标画面。
具体地，通过减少超过了预设电压阈值的第二电压信号持续的时间，来避免高电压信号对应的高亮度画面长时间显示后留下的残影对下一帧画面的干扰，提高画面显示清晰度。
进一步地，像素单元表面蚀刻有第一配向图案和第二配向图案，第一配向图案与第二配向图案平行层叠并错开预设距离。
具体地，像素单元表面蚀刻的第一配向图案和第二配向图案由电极狭缝组成，目前曝光机的解析度与蚀刻制程能力的制程宽度有限，假设制程宽度极限为m，也就是说只能做出宽度为m的电极狭缝，但若是按照本实施例中将两个配向图案层叠错开摆放，两个电极狭缝部分重叠，则重叠的部分即为新的宽度更小的电极狭缝，如此，能进一步增强电极狭缝处的电场强度，进一步减少暗纹。
参见图10，是本申请实施例一和实施例二提供的显示装置500的示意性框图，如图所示，该显示装置500包括：显示面板590、接收单元510、获取单元520、转换单元530以及执行单元540。其中，所述接收单元510用于接收目标画面的图像数据；所述获取单元520用于获取图像数据对应的第一电压信号，即获取像素单元的红色、绿色、蓝色子像素单元对应的电压信号作为第一电压信号；所述转换单元530用于将相邻的第一电压信号转换为电压高低相间分布的第二电压信号所述执行单元540用于驱动显示面板590上的像素单元根据第二电压信号进行响应并显示目标画面。
具体地，在接收单元510接收到目标画面的图像数据后，获取单元520开始获取图像数据对应的第一电压信号，即获取像素单元的红色、绿色、蓝色子像素单元对应的电压信号，在实施例一中，转换单元530用于将相邻的多个蓝色或绿色或红色子像素单元对应的电压信号组转换为电压高低相间分布的电压信号组，电压高低相间分布的电压信号组为第二电压信号。实施例一中用于转化为第二电压信号的蓝色、绿色和红色子像素单元的个数相同，通过相间分布的高地电压信号来达到正视和侧视亮度变化接近的目的。在实施例二中，转换单元530用于将相邻的多个蓝色或绿色或红色子像素单元对应的电压信号组转换为电压高低相间分布的电压信号组，但用于转换成每个第二电压信号的蓝色子像素单元的个数多于用于转换成每个第二电压信号的绿色或红色子像素单元的个数,再由执行单元540驱动像素单元根据第二电压信号进行响应并显示目标画面。因为人眼对绿色和红色的感应更为敏锐，而转换成每个第二电压信号的蓝色子像素单元的个数多于用于转换成每个第二电压信号绿色或红色子像素单元的个数，使得转换后的绿色和红色的第二电压信号的解析度会高于蓝色的第二电压信号的解析度，从而避免了画面的颗粒感。
参见图11，是本申请实施例三提供的一种显示装置600的示意性框图，如图所示，该显示装置600包括：显示面板690、接收单元610、获取单元620、转换单元630、判断单元650、删减单元660以及执行单元640。其中接收单元610，用于接收目标画面的图像数据；获取单元620，用于获取图像数据对应的第一电压信号，即获取像素单元的红色、绿色、蓝色子像素单元对应的电压信号作为第一电压信号；转换单元630，用于将相邻的第一电压信号转换为电压高低相间分布的第二电压信号；判断单元650，用于判断第二电压信号是否超过预设电压阈值；删减单元660，用于若第二电压信号超过预设电压阈值，根据预设删减比例对第二电压信号对应的持续时长进行删减；执行单元640，用于驱动显示面板690上的像素单元根据第二电压信号进行响应并显示目标画面。
具体地，在接收单元610接收到目标画面的图像数据后，获取单元620开始获取图像数据对应的第一电压信号，即获取像素单元的红色、绿色、蓝色子像素单元对应的电压信号，并通过转换单元630将相邻的第一电压信号转换为电压高低相间分布的第二电压信号，转换成第二电压信号后，判断单元650则对第二电压信号时否超过预设电压阈值进行判断，如果超过预设电压阈值，则由删减单元660根据预设删减比例对第二电压信号对应的持续时长进行删减，删减完成后，由执行单元640驱动像素单元根据第二电压信号进行响应并显示目标画面。
在某些实施例中，上述显示面板590或690可例如为扭曲向列型液晶显示面板，平面转换型液晶显示面板或多象限垂直配向型液晶显示面板，OLED显示面板，QLED显示面板，曲面显示面板或其他显示面板。
具体地，通过减少超过了预设电压阈值的第二电压信号持续的时间，来避免高电压信号对应的高亮度画面长时间显示后留下的残影对下一帧画面的干扰，提高画面显示清晰度。

需要说明的是，本申请实施例中的步骤可以根据实际需要进行顺序调整、合并和删减。
