具体实施方式
显示装置的显示面板包括多种色相组合，显示面板为哪种颜色的色相组合，显示面板整体呈现的颜色为该颜色。以显示面板为红色色相组合为例，正视角情况下显示面板中像素的红色分量相对于显示面板中像素的蓝色分量和绿色分量较突出，但是大视角情况下显示面板中像素的红色分量相对于显示面板中像素的蓝色分量和绿色分量的比例严重下降，而显示面板中像素的红色分量相对于显示面板中像素的蓝色分量和绿色分量占据的比例越小，显示面板呈现的颜色越偏离红色，即大视角与正视角的色调偏离越严重，显示面板的色偏问题越严重。
另外，仍以显示面板为红色色相组合为例，低灰阶像素相对于高灰阶像素，其红色分量相对于蓝色分量和绿色分量的比例在正视角和大视角情况下的差异更大，色偏问题更严重。
图1为一实施例提供的一种显示装置的驱动方法的流程示意图，驱动方法可以应用在需要驱动显示装置进行显示的场景，可以由一实施例提供的显示装置来执行。显示装置的一帧原始显示图像中包括至少一个区域，每个区域中包括多个所述像素。当显示装置的一帧原始显示图像中的像素归属于一个区域时，该方法包括：
步骤110、将一帧原始显示图像划分为第一帧显示图像和第二帧显示图像；其中，原始显示图像、第一帧显示图像和第二帧显示图像中的每个像素包括对应预设颜色空间的分量，分量包括第一分量、第二分量和第三分量。
示例性的，可以设置预设颜色空间为RGB颜色空间，则第一分量、第二分量和第三分量分别对应RGB颜色空间中的红色分量、绿色分量和蓝色分量。
步骤120、获取原始显示图像对应的第一平均值、第二平均值和第三平均值；其中，第一平均值、第二平均值和第三平均值分别为原始显示图像对应的第一分量、第二分量和第三分量的平均值，且第一平均值大于第二平均值，第二平均值大于第三平均值。
原始显示图像中的每个像素均对应第一分量、第二分量和第三分量，可以设置原始显示图像中所有像素对应的第一分量的平均值为原始显示图像对应的第一平均值，设置原始显示图像中所有像素对应的第二分量的平均值为原始显示图像对应的第二平均值，设置原始显示图像中所有像素对应的第三分量的平均值为原始显示图像对应的第三平均值，且第一平均值大于第二平均值，第二平均值大于第三平均值。示例性的，可以设置第一分量、第二分量和第三分量分别对应RGB颜色空间中的红色分量、绿色分量和蓝色分量，则显示面板为红色色相组合，即显示面板整体呈现红色。
步骤130、设定第一帧显示图像对应的第一分量、第二分量和第三分量的平均值均等于第二平均值，设定第二帧显示图像对应的第一分量和第三分量的平均值均等于第三平均值，第二分量的平均值等于设定平均值。
示例性的，可以设置原始显示图像对应的第一平均值为A，第二平均值为B，第三平均值为C，且A大于B，B大于C，则可以设定第一帧显示图像对应的第一分量、第二分量和第三分量的平均值均等于B，设定第二帧显示图像对应的第一分量和第三分量的平均值均等于C，设定第二帧显示图像对应的第二分量的平均值等于设定平均值。可选的，由于第一帧显示图像对应的第二分量的平均值等于原始显示图像对应的第二分量的平均值，即二者均等于第二平均值，则可以设置设定平均值等于零，即设定第二帧显示图像对应的第二分量的平均值等于零。
步骤140、根据原始显示图像、第一帧显示图像和第二帧显示图像分别对应的第一分量、第二分量和第三分量的平均值调节背光模块的亮度。
示例性的，可以设置背光模块包括第一背光模块、第二背光模块和第三背光模块，则可以根据原始显示图像、第一帧显示图像和第二帧显示图像分别对应的第一分量的平均值的灰阶亮度值调节第一背光模块的亮度。根据原始显示图像、第一帧显示图像和第二帧显示图像分别对应的第二分量的平均值的灰阶亮度值调节第二背光模块的亮度。根据原始显示图像、第一帧显示图像和第二帧显示图像分别对应的第三分量的平均值的灰阶亮度值调节第三背光模块的亮度。
示例性的，可以设置第一分量、第二分量和第三分量分别对应RGB颜色空间中的红色分量、绿色分量和蓝色分量，则第一背光模块、第二背光模块和第三背光模块分别为红色背光模块、绿色背光模块和蓝色背光模块。根据原始显示图像、第一帧显示图像和第二帧显示图像分别对应的红色分量的平均值的灰阶亮度值调节红色背光模块的亮度。根据原始显示图像、第一帧显示图像和第二帧显示图像分别对应的绿色分量的平均值的灰阶亮度值调节绿色背光模块的亮度。根据原始显示图像、第一帧显示图像和第二帧显示图像分别对应的蓝色分量的平均值的灰阶亮度值调节蓝色背光模块的亮度。
参照步骤130，可以设置在正视角情况下，原始显示图像对应的第一分量的平均值、第二分量的平均值和第三分量的平均值的灰阶亮度值分别为TR1(A)、TG1(B)和TB1(C)，第一帧显示图像对应的第一分量的平均值、第二分量的平均值和第三分量的平均值的灰阶亮度值分别为TR2(B)、TG2(B)和TB2(B)，第二帧显示图像对应的第一分量的平均值、第二分量的平均值和第三分量的平均值的灰阶亮度值分别为TR3(C)、TG3(0)和TB3(C)，设置第一背光模块、第二背光模块和第三背光模块调节前的亮度分别为AR、AG和AB，则第一背光模块、第二背光模块和第三背光模块调节后的亮度AR1、AG1和AB1满足如下计算公式：
Figure PCTCN2018080916-appb-000001
Figure PCTCN2018080916-appb-000002
Figure PCTCN2018080916-appb-000003
由于将一帧原始显示图像划分为第一帧显示图像和第二帧显示图像，每一帧显示图像的显示时间变为原来一帧显示图像的一半，因此在上述公式中，除了考虑分量因素，还需在背光模块调整前亮度的基础上乘以2，即通过背光模块亮度的调整弥补显示时间的变化。
示例性的，设置A等于100，B等于80，C等于40，即原始显示图像对应的第一分量的平均值、第二分量的平均值和第三分量的平均值分别为100、80和 40，则可以设定第一帧显示图像对应的第一分量的平均值、第二分量的平均值和第三分量的平均值均为80，设定第二帧显示图像对应的第一分量的平均值和第三分量的平均值均为40，第二帧显示图像对应的第二分量的平均值为0。
示例性的，参照VA型液晶显示面板的光电特性，以灰阶值的数据格式为8比特(灰阶值为0-255灰阶)为例，灰阶值亮度与灰阶值满足如下公式：
Figure PCTCN2018080916-appb-000004
其中，X表示灰阶值，即前面实施例提到的分量，Y表示灰阶值亮度，即归一化亮度，也即前面实施例提到的分量的平均值的灰阶亮度值，二者符合指数幂次2.2的关系式，可以通过查表或根据上述公式确定需要获得的灰阶值亮度，则TR1(A)、TG1(B)和TB1(C)分别为13.3％、7.4％和1.7％，TR2(B)、TG2(B)和TB2(B)分别为8.2％、7.4％和7.4％，TR3(C)、TG3(0)和TB3(C)分别为1.8％、0和1.7％，按照上述公式可得AR1等于2.66倍的AR，AG1等于2倍的AG，AB1等于0.347倍的AB。
示例性的，参照VA型液晶显示面板的光电特性，正视角情况下灰阶值与灰阶值亮度符合上述指数幂次2.2的关系式.侧视角情况下灰阶值与灰阶值亮度同样一一对应，与VA型液晶显示面板的画素设计相关，示例性的，侧视角情况满足如下情况：当原始显示图像对应的第一分量的平均值A、第二分量的平均值B和第三分量的平均值C分别为100、80和40，第一帧显示图像对应的第一分量的平均值、第二分量的平均值和第三分量的平均值均为80，第二帧显示图像对应的第一分量的平均值和第三分量的平均值均为40，第二帧显示图像对应的第二分量的平均值为0时，原始显示图像每个像素的三个分量的灰阶亮度值TR1(A)、TG1(B)和TB1(C)分别为39％、34.7％和23.1％，第一帧显示图像每个像素的三个分量的灰阶亮度值TR2(B)、TG2(B)和TB2(B)分别为32.6％、34.7％和42.1％，第二帧显示图像每个像素的三个分量的灰阶亮度值TR3(C)、TG3(0)和TB3(C)分别为17.6％、0和23.1％，则针对第一帧显示图像和第二帧显示图像，第一分量的灰阶亮度值的比例D1、第二分量的灰阶亮度值的比例D2和第三分量的灰阶亮度值的比例D3满足以下公式：
D1＝2.66×[TR2(B)+TR3(C)]
D2＝2×[TG2(B)+TG3(0)]
D3＝0.374×[TB2(B)+TB3(C)]
将参数带入上述D1、D2和D3的计算公式得到D1等于133.5％，D2等于69.4％，D3等于24.4％，相对于侧视角情况下TR1(A)、TG1(B)和TB1(C)分别为39％、34.7％和23.1％，红色分量相对于绿色分量的比例由39％与34.7％的比值等于1.124，提升为133.5％与69.4％的比值等于1.924，红色分量相对于蓝色分量的比例由39％与23.1％的比值等于1.688，提升为133.5％与24.4％的比值等于5.471， 有效提高了主色调分量，例如红色分量的灰阶亮度值比例，提高了侧视角情况下主色调分量相对于其它分量的灰阶亮度值比例，使得显示面板呈现的颜色更接近主色调，改善了显示面板在大视角情况下的色偏问题，并改善了低灰阶像素相对于高灰阶像素，其主色调分量相对其它分量的灰阶亮度值比例在正视角和大视角情况下的差异更大的问题，同样改善了显示面板在大视角情况下的色偏问题。
步骤150、根据背光模块调节前后的亮度、原始显示图像中一像素对应的分量以及第一帧显示图像中该像素对应的驱动分量获取第二帧显示图像中该像素对应的驱动分量；其中，第一帧显示图像中该像素对应的驱动分量等于原始显示图像中该像素对应的次大分量。
示例性的，可以设置背光模块包括第一背光模块、第二背光模块和第三背光模块，根据第一背光模块调整前后的亮度、原始显示图像中一像素对应的第一分量以及第一帧显示图像中该像素对应的驱动分量获取第二帧显示图像中对应该像素第一分量的驱动分量，根据第二背光模块调整前后的亮度、原始显示图像中一像素对应的第二分量以及第一帧显示图像中该像素对应的驱动分量获取第二帧显示图像中对应该像素第二分量的驱动分量，根据第三背光模块调整前后的亮度、原始显示图像中一像素对应的第三分量以及第一帧显示图像中该像素对应的驱动分量获取第二帧显示图像中对应该像素第三分量的驱动分量。
示例性的，可以设置第一分量、第二分量和第三分量分别对应RGB颜色空间中的红色分量、绿色分量和蓝色分量，则第一背光模块、第二背光模块和第三背光模块分别为红色背光模块、绿色背光模块和蓝色背光模块。根据红色背光模块调整前后的亮度、原始显示图像中一像素对应的红色分量以及第一帧显示图像中该像素对应的驱动分量获取第二帧显示图像中对应该像素的红色分量的驱动分量，根据绿色背光模块调整前后的亮度、原始显示图像中一像素对应的绿色分量以及第一帧显示图像中该像素对应的驱动分量获取第二帧显示图像中对应该像素绿色分量的驱动分量，根据蓝色背光模块调整前后的亮度、原始显示图像中一像素对应的蓝色分量以及第一帧显示图像中该像素对应的驱动分量获取第二帧显示图像中对应该像素蓝色分量的驱动分量。
参照步骤130和步骤140，第一种情况，原始显示图像中的像素对应的第一分量、第二分量和第三分量的大小关系与原始显示图像对应的第一分量的平均值、第二分量的平均值和第三分量的平均值的大小关系相同，即原始显示图像对应的第一分量的平均值大于第二分量的平均值，第二分量的平均值大于第三分量的平均值，原始显示图像中该像素对应的第一分量大于第二分量，第二分量大于第三分量。
示例性的，可以设置原始显示图像中该像素对应的第一分量、第二分量和第三分量分别为A1、B1和C1，且A1大于B1，B1大于C1，三者对应的灰阶亮度值分别为TR1(A1)、TG1(B1)和TB1(C1)，设定第一帧显示图像中该像素对应第一分量的驱动分量、对应第二分量的驱动分量和对应第三分量的驱动分 量均为B1，即设定第一帧显示图像中该像素对应的驱动分量均等于原始显示图像中该像素对应的次大分量B1，三者对应的灰阶亮度值分别为TR2(B1)、TG2(B1)和TB2(B1)，结合上述背光模块调节后的亮度AR1、AG1和AB1的计算公式，第二帧显示图像中对应该像素第一分量的驱动分量TR3、对应该像素第二分量的驱动分量TG3和对应该像素第三分量TB3的驱动分量满足以下公式：

Figure PCTCN2018080916-appb-000006
Figure PCTCN2018080916-appb-000007
第二种情况，原始显示图像中的像素对应的第一分量、第二分量和第三分量的大小关系与原始显示图像对应的第一分量的平均值、第二分量的平均值和第三分量的平均值的大小关系不同，示例性的，原始显示图像对应的第一分量的平均值大于第二分量的平均值，第二分量的平均值大于第三分量的平均值，原始显示图像中该像素对应的第二分量大于第三分量，第三分量大于第一分量。
示例性的，可以设置原始显示图像中该像素对应的第一分量、第二分量和第三分量分别为A2、B2和C2，且B2大于C2大于A2，三者对应的灰阶亮度值分别为TR1(A2)、TG1(B2)和TB1(C2)，设定第一帧显示图像中该像素对应第一分量的驱动分量、对应第二分量的驱动分量和对应第三分量的驱动分量分别为C2、C2和C2，即设定第一帧显示图像中该像素对应的驱动分量均等于原始显示图像中该像素对应的次大分量C2，三者对应的灰阶亮度值分别为TR2(C2)、TG2(C2)和TB2(C2)，结合上述背光模块调节后的亮度AR1、AG1和AB1的计算公式，第二帧显示图像中对应该像素第一分量的驱动分量TR3、对应该像素第二分量的驱动分量TG3和对应该像素第三分量TB3的驱动分量满足以下公式：

Figure PCTCN2018080916-appb-000009
Figure PCTCN2018080916-appb-000010
步骤160、根据获取的第二帧显示图像中该像素对应的驱动分量，判定根据原始显示图像对应的分量驱动显示装置中的像素单元进行显示，或者根据第一 帧显示图像对应的驱动分量和第二帧显示图像对应的驱动分量驱动显示装置中的像素单元进行显示。
针对上述第二种情况，由于原始显示图像中的像素对应的第一分量、第二分量和第三分量的大小关系与原始显示图像对应的第一分量的平均值、第二分量的平均值和第三分量的平均值的大小关系不同，因此根据上述公式求得的TR31、TG31和TB31可能存在小于零，或大于原始图像中该像素对应的，以8比特灰阶值为例，最大分量例如可以是255灰阶。
可选的，若第二帧显示图像中，驱动分量小于第一设定分量的像素的比例大于第一设定值，则根据原始显示图像对应的分量驱动显示装置中的像素单元进行显示；若第二帧显示图像中，驱动分量小于第一设定分量的像素的比例小于第一设定值，则根据第一帧显示图像对应的驱动分量和第二帧显示图像对应的驱动分量驱动显示装置中的像素单元进行显示；若第二帧显示图像中，驱动分量大于第二设定分量的像素的比例大于第二设定值，则根据原始显示图像对应的分量驱动显示装置中的像素单元进行显示；若第二帧显示图像中，驱动分量大于第二设定分量的像素的比例小于第二设定值，则根据第一帧显示图像对应的驱动分量和第二帧显示图像对应的驱动分量驱动显示装置中的像素单元进行显示。
示例性的，可以设置第一设定分量等于零，第二设定分量等于原始图像中该像素对应的最大分量，以8比特灰阶值为例，最大分量例如可以是255灰阶，第一设定值和第二设定值均采用百分比表示，且第一设定值和第二设定值小于1。示例性的，当第二帧显示图像中，驱动分量小于零的像素在连续像素构成的k*k矩阵中占据的比例大于第一设定值，或者驱动分量小于零的像素多个像素构成的n*m矩阵中占据的比例大于第一设定值时，则不再对一帧原始显示图像进行拆分，即根据原始显示图像对应的分量驱动显示装置中的像素单元进行显示。相反的，当驱动分量小于零的像素占据的比例小于第一设定值时，则仍然将一帧原始显示图像拆分成第一帧显示图像和第二帧显示图像，即根据第一帧显示图像对应的驱动分量和第二帧显示图像对应的驱动分量驱动显示装置中的像素单元进行显示。
示例性的，当第二帧显示图像中，驱动分量大于原始图像中该像素对应的最大分量，以8比特灰阶值为例，最大分量例如可以是255灰阶的像素在k*k个连续像素构成的矩阵中占据的比例大于第一设定值，或者驱动分量大于原始图像中该像素对应的最大分量，以8比特灰阶值为例，最大分量例如可以是255灰阶的像素多个像素构成的n*m矩阵中占据的比例大于第二设定值时，则不再对一帧原始显示图像进行拆分，即根据原始显示图像对应的分量驱动显示装置中的像素单元进行显示。相反的，当驱动分量大于原始图像中该像素对应的最大分量，以8比特灰阶值为例，最大分量例如可以是255灰阶的像素占据的比例小于第二设定值时，则仍然将一帧原始显示图像拆分成第一帧显示图像和第二帧显示图像，即根据第一帧显示图像对应的驱动分量和第二帧显示图像对应 的驱动分量驱动显示装置中的像素单元进行显示。
通过根据获取的第二帧显示图像中像素对应的驱动分量判定是根据原始显示图像对应的分量，或者根据第一帧和第二帧显示图像对应的驱动分量驱动显示装置进行显示，保证了显示装置显示效果的优化。
分量即为灰阶值，每一灰阶值均对应一像素单元的驱动电压，当根据第一帧显示图像和第二帧显示图像对应的驱动分量驱动显示装置中的像素单元进行显示时，当原始显示图像中的像素对应的第一分量、第二分量和第三分量大小关系与原始显示图像对应的第一分量的平均值、第二分量的平均值和第三分量的平均值的大小关系相同时，可以根据上述公式求得的第二帧显示图像中的像素对应的驱动分量，即TR3、TG3和TB3分别对应的灰阶值，以及第一帧显示图像中像素对应的驱动分量，即B1，分别驱动显示装置中的红色像素单元、绿色像素单元以及蓝色像素单元进行显示。当原始显示图像中的像素对应的第一分量、第二分量和第三分量的大小关系与原始显示图像对应的第一分量的平均值、第二分量的平均值和第三分量的平均值的大小关系不同时，可以根据上述公式求得的第二帧显示图像中的像素对应的驱动分量，即TR31、TG31和TB31分别对应的灰阶值，以及第一帧显示图像中像素对应的驱动分量，即C2，分别驱动显示装置中的红色像素单元、绿色像素单元以及蓝色像素单元进行显示。
可选的，可以设定第二帧显示图像中该像素对应的设定分量对应的背光模块的亮度为零；其中，设定分量对应原始显示图像中该像素对应的次大分量。参照步骤150，针对第一种情况，即原始显示图像中的像素对应的第一分量、第二分量和第三分量的大小关系与原始显示图像对应的第一分量的平均值、第二分量的平均值和第三分量的平均值的大小关系相同时，以第一分量、第二分量和第三分量分别对应RGB颜色空间中的红色分量、绿色分量和蓝色分量为例，则获取的第二帧显示图像中该像素对应的绿色分量的灰阶亮度值TG3始终为零，如果与该像素对应的绿色背光模块仍发光，则会造成能量的浪费。通过设定第二帧显示图像中该像素对应的设定分量对应的背光模块的亮度为零，即设定第二帧显示图像中对应原始显示图像中该像素对应的次大分量的设定分量，设定分量对应的背光模块的亮度为零，起到节能的作用。
参照步骤150，针对第二种情况，即原始显示图像中的像素对应的第一分量、第二分量和第三分量的大小关系与原始显示图像对应的第一分量的平均值、第二分量的平均值和第三分量的平均值的大小关系不同时，以第一分量、第二分量和第三分量分别对应RGB颜色空间中的红色分量、绿色分量和蓝色分量为例，则获取的第二帧显示图像中该像素对应的绿色分量的灰阶亮度值TG31＝TG1(B2)-TG2(C2)，即TG31不等于零，设定第二帧显示图像中对应原始显示图像中该像素对应的次大分量的设定分量，设定分量对应的背光模块的亮度为零可能会导致该像素对应显示装置中的像素单元无法正常显示，但是由于原始显示图像对应的第一平均值大于第二平均值，第二平均值大于第三平均值，即显示面板显示的颜色整体呈现红色，只存在极少数像素对应的第一分量、第二分量和第 三分量的大小关系与原始显示图像对应的第一分量的平均值、第二分量的平均值和第三分量的平均值的大小关系不同，因此，设定第二帧显示图像中对应原始显示图像中该像素对应的次大分量的设定分量，其对应的背光模块的亮度为零并不影响整体画质的输出结果。
