现有的大尺寸液晶显示面板大多数采用负型VA液晶或IPS液晶技术，VA型液晶技术相较于IPS液晶技术存在较高的生产效率及低制造成本的优势，但光学性质上相较于IPS液晶技术存在较明显的光学性质缺陷，尤其是大尺寸面板在商业应用方面需要较大的视角呈现，VA型液晶驱动在视角色偏往往无法符合市场应用需求，这影响了VA型液晶技术的推广。
一般VA型液晶技术解决视角色偏的方式是将RGB各基色再划分为主次像素，经空间上主次像素给予不同的驱动电压来解决视角色偏的缺陷，这样的像素设计往往需要再设计金属走线或薄膜晶体管元件来驱动次像素，造成可透光开口区牺牲，影响面板穿透率，直接造成背光模组成本的提升。

图1为根据本申请实施例的显示装置的驱动方法的流程图，该显示装置的驱动方法，包括以下步骤:
S100、接收待显示图像，获取像素的像素信号及位置信息，对像素信号进行查表，得到各个像素的一子像素的第一电压驱动信号和第二电压驱动信号；
S200、根据位置信息判断像素为第一位置子像素或第二位置子像素；
S300、当像素为第一位置子像素时，根据第一位置子像素及其相邻的第二位置子像素的第二电压驱动信号计算第二亮度信号；
S400、当像素为第二位置子像素时，根据第二位置子像素及其相邻的第一位置子像素的第一电压驱动信号计算第一亮度信号；
S500、对第一位置子像素采用第二亮度信号驱动，对第二位置子像素采用第一亮度信号驱动。
显示装置的一幅图像通常由多个像素构成，这些像素组成N行M列，即共有N*M个像素。每个像素包括红(R) 、绿(G) 、蓝(B)三种颜色分量，因此，每个像素由这三种颜色的子像素构成，每个图像像素的显示颜色为其对应的三个子像素的显示颜色的混合，每个子像素的颜色由该子像素的灰阶值确定，而灰阶值由该子像素的驱动信号电压值确定。
第二电压驱动信号RH/GH/BH与第一电压驱动信号RL/GL/BL，为事先根据RGB输入信号的亮度值给予的预设第二第一电压信号，是依照需要补偿的视角效果所决定，在显示装置生产时已经将相关数据烧录至显示装置里。一般是以LUT（Look Up Table，显示查找表）的方式记录在硬件缓冲器里面，以8 bit驱动信号来看每一R/G/B输入信号输入0 ～255共对应256第二第一电压信号，共有 3*256对第二电压信号RH/GH/BH与第一电压信号RL/GL/BL。
以图3为例，图3为像素图像中一部分红色R子像素的亮度值，其中R1-R100表示其中100个R子像素的亮度值：
图3中的R子像素亮度值经过查表分别得到图4每个R子像素的第二电压驱动信号值H1-H100和图5每个R子像素的第一电压驱动信号值L1-L100：
以图3上的R子像素分布为例，根据其每个子像素的行和列的位置关系，可将其分成第一位置子像素和第二位置子像素，第二位置和第一位置像素的子像素相邻交错间隔分布，且每一个第二位置的子像素周围相邻四个第一位置的子像素，每一个第一位置的子像素周围相邻四个第二位置的子像素。
如以最上的两行像素根据其位置分成第一位置子像素和第二位置子像素，第一位置子像素为R1、R3、R5、R7、R9、R12、R14、R16、R18、R20，第二位置子像素为R2、R4、R6、R8、R10、R11、R13、R15、R17、R19，这两部分的像素是相互相邻间隔交错分布的，同理可以将剩下的像素分别分到上述第一位置和第二位置中。概括来说，处于n行m列位置的子像素Rnm为第二像素时，其与之相邻的四个第一位置子像素分别是R n(m-1)、R n(m+1)、R(n-1)m、R(n+1)m，或者处于n行m列位置的子像素Rnm为第一像素时，其与之相邻的四个第二位置子像素分别是R n(m-1)、R n(m+1)、R(n-1)m、R(n+1)m。
以图5中属于第二位置的子像素的R24对应的第一电压驱动信号值L24为例，R24子像素与之相邻对属于第一位置的周围四个同色子像素分别是R14、R23、R25、R34，其第一电压驱动信号值分别是L24、L14、L23、L25、L34，则R24的第一亮度信号值L’24可以基于以下公式计算：
L’nm=a*Lnm+b*（Ln(m-1)+Ln(m+1)+L(n-1)m+L(n+1)m）
这里n为2，m为4，代入上述公式得到：
L’24= a*L24+b*( L23+L25+L14+L34)
a、b表示权重因子，通过实验可以取值为a=1，b=0.25，代入公式得到：
L’24= L24+0.25*( L14+L23+L25+L34)
即第二位置子像素R24的第一亮度信号值L’24计算除了自身的第一电压驱动信号值外，还另外考量了与之相邻的第一位置的周围四个同色子像素R14、R23、R25、R34的第一电压驱动信号值，并给予相应的权重，上述公式中，其周围四个同色子像素的权重为0.25，以此亮度值做为第一灰阶亮度值控制该子像素的颜色显示。
以上是以R子像素为例获得第一亮度信号值，同理G和B子像素可以通过相同的方法获得其第一亮度信号值。
以图4中的属于第一位置的子像素R14对应的第二电压驱动信号值H14为例，R14子像素与之相邻对称分布属于第二位置的周围四个同色子像素分别是R4、R13、R15、R24，其第二电压驱动信号值分别是H14、H4、H13、H15、H24，则R14的第二电压驱动信号值H’14可以基于以下公式计算：
H’nm=a* H nm+b*（H n(m-1)+ H n(m+1)+ H (n-1)m+ H (n+1)m）
这里n为1，m为4，代入上述公式得到：
H’14= a*H14+ b *( H4+H13+H15+H24)
a、b表示权重因子，通过实验可以取值为a=1，b=0.25，代入公式得到：
H’14= H14+0.25*( H4+H13+H15+H24)
即第一位置子像素R14的第二亮度信号值H’14计算除了自身的第二电压驱动信号值外，还另外考量了与之相邻的属于第二位置的周围四个同色子像素R4、R13、R15、R24的第二电压驱动信号值，并给予相应的权重，上述公式中，其周围四个同色子像素的权重为0.25，以此亮度值做为第二灰阶亮度值控制该子像素的颜色显示。
通过上述步骤获得第二亮度信号和第一亮度信号值后，其对应的像素是相邻间隔交错分布的，如图6所示
可以看出图6中，第二亮度信号值和第一亮度信号值对应的子像素相邻间隔交错分布，然后以上述第二亮度信号值和第一亮度信号值控制对应的子像素在同一帧显示。
值得说明的是，上述计算第二位置的子像素的第一亮度信号和第一位置子像素的第二亮度信号的公式在应用过程中，对面板四周最外侧的左右两列和上下两行的像素在计算时，会有一些像素不存在，此时将不存在的像素的第一电压驱动信号或者第二电压驱动信号记为0，如在计算第一位置子像素R1的第二亮度信号值时，由于其子像素位置相邻上方的子像素以及相邻左侧的子像素对应的像素不存在，则这两个子像素对应的第二电压驱动信号L(n-1)m和Ln(m-1)记为0。
本实施例中，通过接收待显示图像，获取像素的像素信号及位置信息，对像素信号进行查表，得到各个像素的子像素的第一电压驱动信号和第二电压驱动信号，根据位置信息判断像素为第一位置像素或第二位置子像素，进一步将第二位置的子像素和周围相邻的第一位置子像素的第一电压驱动信号计算第二位置子像素的第一亮度信号，以及将第一位置的子像素和周围相邻的第二位置子像素的第二电压驱动信号计算第一位置子像素的第二亮度信号，最后对第一位置子像素采用第二亮度信号驱动，对第二位置子像素采用第一亮度信号驱动，在同一帧控制所述子像素显示，由于其每个子像素的第二亮度信号值或第一亮度信号值的大小都考量了周围相邻的四个子像素的第二亮度信号值或第一亮度信号值大小，因此可以解决视角色偏问题同时又兼顾了图像解析度。本申请技术方案无需在面板上设置主次像素，从而无需设计金属走线和薄膜晶体管元件来驱动次像素，简化了生产工艺，降第一了成本，同时由于去掉了次像素，提第二了面板的穿透率。
基于上述显示装置的驱动方法，本申请还提出一种显示装置的驱动装置，图2为本申请实施例的显示装置的驱动装置的结构示意图，该显示装置的驱动装置包括：
信号获取模块10，用于接收待显示图像，获取像素的像素信号及位置信息，对像素信号进行查表，得到各个像素的第一电压驱动信号和第二电压驱动信号；
位置判断模块20，用于根据位置信息判断像素为第一位置子像素或第二位置子像素；
第二亮度信号计算模块30，用于当像素为第一位置子像素时，根据第一位置子像素及其相邻的第二位置子像素的第二电压驱动信号计算第二亮度信号；
第一亮度信号计算模块40，用于当像素为第二位置子像素时，根据第二位置子像素及其相邻的第一位置子像素的第一电压驱动信号计算第一亮度信号；
驱动模块50，用于对第一位置子像素采用第二亮度信号驱动，对第二位置子像素采用第一亮度信号驱动。
显示装置的一幅图像通常由多个像素构成，这些像素组成N行M列，即共有N*M个像素。每个像素包括红(R) 、绿(G) 、蓝(B)三种颜色分量，因此，每个像素由这三种颜色的子像素构成，每个图像像素的显示颜色为其对应的三个子像素的显示颜色的混合，每个子像素的颜色由该子像素的灰阶值确定，而灰阶值由该子像素的驱动信号电压值确定。
第二电压驱动信号RH/GH/BH与第一电压驱动信号RL/GL/BL，为事先根据RGB输入信号的亮度值给予的预设第二第一电压信号，是依照需要补偿的视角效果所决定，在显示装置生产时已经将相关数据烧录至显示装置里。一般是以LUT（Look Up Table，显示查找表）的方式记录在硬件缓冲器里面，以8 bit驱动信号来看每一R/G/B输入信号输入0 ～255共对应256第二第一电压信号，共有 3*256对第二电压信号RH/GH/BH与第一电压信号RL/GL/BL。
以图3为例，图3为像素图像中一部分红色R子像素的亮度值，其中R1-R100表示其中100个R子像素的亮度值：
图3中的R子像素亮度值经过查表分别得到图4每个R子像素的第二电压驱动信号值H1-H100和图5每个R子像素的第一电压驱动信号值L1-L100：
以图3上的R子像素分布为例，根据其每个子像素的行和列的位置关系，可将其分成第一位置子像素和第二位置子像素，第二位置和第一位置像素的子像素相邻交错间隔分布，且每一个第二位置的子像素周围相邻四个第一位置的子像素，每一个第一位置的子像素周围相邻四个第二位置的子像素。
如以最上的两行像素根据其位置分成第一位置子像素和第二位置子像素，第一位置子像素为R1、R3、R5、R7、R9、R12、R14、R16、R18、R20，第二位置子像素为R2、R4、R6、R8、R10、R11、R13、R15、R17、R19，这两部分的像素是相互相邻间隔交错分布的，同理可以将剩下的像素分别分到上述第一位置和第二位置中。概括来说，处于n行m列位置的子像素Rnm为第二像素时，其与之相邻的四个第一位置子像素分别是R n(m-1)、R n(m+1)、R(n-1)m、R(n+1)m，或者处于n行m列位置的子像素Rnm为第一像素时，其与之相邻的四个第二位置子像素分别是R n(m-1)、R n(m+1)、R(n-1)m、R(n+1)m。
以图5中属于第二位置的子像素的R24对应的第一电压驱动信号值L24为例，R24子像素与之相邻对属于第一位置的周围四个同色子像素分别是R14、R23、R25、R34，其第一电压驱动信号值分别是L24、L14、L23、L25、L34，则R24的第一亮度信号值L’24可以基于以下公式计算：
L’nm=a*Lnm+b*（Ln(m-1)+Ln(m+1)+L(n-1)m+L(n+1)m）
这里n为2，m为4，代入上述公式得到：
L’24= a*L24+b*( L23+L25+L14+L34)
a、b表示权重因子，通过实验可以取值为a=1，b=0.25，代入公式得到：
L’24= L24+0.25*( L14+L23+L25+L34)
即第二位置子像素R24的第一亮度信号值L’24计算除了自身的第一电压驱动信号值外，还另外考量了与之相邻的第一位置的周围四个同色子像素R14、R23、R25、R34的第一电压驱动信号值，并给予相应的权重，上述公式中，其周围四个同色子像素的权重为0.25，以此亮度值做为第一灰阶亮度值控制该子像素的颜色显示。
以上是以R子像素为例获得第一亮度信号值，同理G和B子像素可以通过相同的方法获得其第一亮度信号值。
以图4中的属于第一位置的子像素R14对应的第二电压驱动信号值H14为例，R14子像素与之相邻对称分布属于第二位置的周围四个同色子像素分别是R4、R13、R15、R24，其第二电压驱动信号值分别是H14、H4、H13、H15、H24，则R14的第二电压驱动信号值H’14可以基于以下公式计算：
H’nm=a* H nm+b*（H n(m-1)+ H n(m+1)+ H (n-1)m+ H (n+1)m）
这里n为1，m为4，代入上述公式得到：
H’14= a*H14+ b *( H4+H13+H15+H24)
a、b表示权重因子，通过实验可以取值为a=1，b=0.25，代入公式得到：
H’14= H14+0.25*( H4+H13+H15+H24)
即第一位置子像素R14的第二亮度信号值H’14计算除了自身的第二电压驱动信号值外，还另外考量了与之相邻的属于第二位置的周围四个同色子像素R4、R13、R15、R24的第二电压驱动信号值，并给予相应的权重，上述公式中，其周围四个同色子像素的权重为0.25，以此亮度值做为第二灰阶亮度值控制该子像素的颜色显示。
通过上述步骤获得第二亮度信号和第一亮度信号值后，其对应的像素是相邻间隔交错分布的，如图6所示
可以看出图6中，第二亮度信号值和第一亮度信号值对应的子像素相邻间隔交错分布，然后以上述第二亮度信号值和第一亮度信号值控制对应的子像素在同一帧显示。
值得说明的是，上述计算第二位置的子像素的第一亮度信号和第一位置子像素的第二亮度信号的公式在应用过程中，对面板四周最外侧的左右两列和上下两行的像素在计算时，会有一些像素不存在，此时将不存在的像素的第一电压驱动信号或者第二电压驱动信号记为0，如在计算第一位置子像素R1的第二亮度信号值时，由于其子像素位置相邻上方的子像素以及相邻左侧的子像素对应的像素不存在，则这两个子像素对应的第二电压驱动信号L(n-1)m和Ln(m-1)记为0。
本实施例中，通过接收待显示图像，获取像素的像素信号及位置信息，对像素信号进行查表，得到各个像素的子像素的第一电压驱动信号和第二电压驱动信号，根据位置信息判断像素为第一位置像素或第二位置子像素，进一步将第二位置的子像素和周围相邻的第一位置子像素的第一电压驱动信号计算第二位置子像素的第一亮度信号，以及将第一位置的子像素和周围相邻的第二位置子像素的第二电压驱动信号计算第一位置子像素的第二亮度信号，最后对第一位置子像素采用第二亮度信号驱动，对第二位置子像素采用第一亮度信号驱动，在同一帧控制所述子像素显示，由于其每个子像素的第二亮度信号值或第一亮度信号值的大小都考量了周围相邻的四个子像素的第二亮度信号值或第一亮度信号值大小，因此可以解决视角色偏问题同时又兼顾了图像解析度。本申请技术方案无需在面板上设置主次像素，从而无需设计金属走线和薄膜晶体管元件来驱动次像素，简化了生产工艺，降第一了成本，同时由于去掉了次像素，提第二了面板的穿透率。
