请参阅图2，本申请提供一种显示驱动方法，包括：
S110：获取待显示内容在预设显示区域内的各色相的原光源强度。
可以通过查找数据表的方式，获取待显示内容在预设显示区域内的各色相的原光源强度，即待显示内容在预设显示区域内的原光源强度组。可以理解地，该数据表可预先存在存储器中，需要时直接调用；也可以在需要时获取该数据表，从而获取待显示内容在预设显示区域内的原光源强度组。可以用(An，m_R、An，m_G、An，m_B)表示获取待显示内容在第n列m行的显示区域内的原光源强度组。
S120：将显示区域内的驱动光源强度设置为原光源强度的三倍。
在本实施方式中，需要将预设显示区域内的各像素单元的原灰阶数据组分解为三个灰阶数据组，因此，需要将预设预设区域内的驱动光源强度设置为原光源强度的三倍，以补偿因灰阶分解而降低的亮度。该预设显示区域(n，m)内R、G、B各色相的原光源强度为An，m_R、An，m_G、An，m_B将调整为驱动光源强度A’n，m_R、A’n，m_G、A’n，m_B，其中，A’n，m_R＝3*An，m_R、A’n，m_G＝3*An，m_G、A’n，m_B＝3*An，m_B。
S130：获取待显示内容在预设显示区域内的各像素单元的原灰阶数据组。
液晶显示器是由多个RGB子像素单元构成，每一组RGB子像素单元称之为一像素单元，每一像素单元代表一个影像信号。每一像素单元的原灰阶数据组均包括R、G、B三种色相的灰阶，如可以用(Rn，m_i，j，Gn，m_i，j，Bn，m_i，j)表示第n列m行的显示区域中的第i列j行的像素单元的原灰阶数据组。可以将液晶显示器的显示区划分成多个显示区域，每个显示区域包括至少两个像素单元，显示区域的大小可以自行定义，在液晶显示器上可分成N(列)*M(行)个由像素单元构成的显示分区。可以按照预设顺序依次将各显示区域作为预设显示区域，进而实现显示驱动方法。
S170：根据各像素单元的原灰阶数据组，将原灰阶数据组分解成第一灰阶数据组、第二灰阶数据组及第三灰阶数据组；第一灰阶数据组的各色相的灰阶为原灰阶数据组中的最小灰阶，第二灰阶数据组的各色相的灰阶为灰阶差值或灰阶差值的共同灰阶，第三灰阶数据组为原灰阶数据组与灰阶和值的差值；灰阶差值为原灰阶数据组与第一灰阶数据组中色相的灰阶的差值，灰 阶和值为第一灰阶数据组及第二灰阶数据组中色相的灰阶的和。
上述显示驱动方法，通过将原灰阶数据组分解成第一灰阶数据组、第二灰阶数据组及第三灰阶数据组，即将各个像素单元对应的原图框信号作多图框组合，且第一灰阶数据组的各色相的灰阶为原灰阶数据组中的最小灰阶，第二灰阶数据组的各色相的灰阶为灰阶差值或灰阶差值的共同灰阶，第三灰阶数据组为原灰阶数据组与灰阶和值的差值；灰阶差值为原灰阶数据组与第一灰阶数据组中色相的灰阶的差值，灰阶和值为第一灰阶数据组及第二灰阶数据组中色相的灰阶的和。如此，为了突出主色和改善色偏，将原灰阶数据组中的最大灰阶对应的色相的灰阶分解成三个小于该最大灰阶的灰阶数据组合，使得三个小于最大灰阶的灰阶数据组合的侧视角组合亮度相对于原最大灰阶的视角亮度提升，突出了视角最大灰阶主色对于最小灰阶非主色亮度的比例，从而减少低灰阶侧视角子像素色相对于整体像素色相的亮度差异，使得侧视角色相接近正视角色相呈现。
请参阅图3，在其中一实施方式中，将原灰阶数据组分解成第一灰阶数据组、第二灰阶数据组及第三灰阶数据组的步骤之前，即步骤S170之前，还包括：
S140：根据原灰阶数据组，确定预设显示区域内的平均灰阶。
根据预设显示区域内各像素单元的原灰阶数据组可以确定该预设显示区域内各色相的平均灰阶。可以通过对各像素单元的原灰阶数据组各色相分别求和之后，再除以该预设显示区域内的像素单元的数量，从而得到该预设显示区域内各色相的平均灰阶，即预设显示区域的平均灰阶组。如可以用(Ave_Rn，m，Ave_Gn，m，Ave_Bn，m)表示第n列m行的显示区域的平均灰阶组。
S150：获取预设显示区域的平均色相及饱和度。
可以根据预设显示区域内的平均灰阶，采用颜色空间系统确定预设显示区域的平均色相及饱和度的方式获取到该预设显示区域的平均色相及饱和度。其中，颜色空间系统可以为CIE LCH颜色空间系统，其中是CIE LCH是 CIE(Commission Internationale de L′Eclairage，国际照明委员会)提出的一种R、G、B三色空间坐标系统。该坐标系统包括L(亮度)、C(纯度)、H(色相)，可以通过CIE规范的坐标函数来确定，这些坐标函数可以分别表示为：L＝f1(R、G、B)，C＝f1(R、G、B)，H＝f1(R、G、B)。其中H为颜色代表，由00～3600代表不同色相颜色呈现，其中定义00为红色，900为黄色，1800为绿色，2700为蓝色。C为色彩纯度，代表颜色的鲜艳程度，C的范围表示为0到100，100代表最色彩最为鲜艳，C的数值一定程度表现了LCD显示高低电压信号的呈现。
S160：根据平均色相、饱和度及平均灰阶确定在显示第二灰阶数据组或第三灰阶数据组时，将预设显示区域内预设色相的驱动光源强度设置为0。具体包括以下方式：
在一个实施例中，当预设显示区域的平均色相Hn，m满足在3300到300区间且色饱和度属于第一自定义色饱和度范围CTL1～CTH1时，若平均灰阶的最小灰阶对应的色相为蓝色、次小灰阶对应的色相为绿色，则在显示第二灰阶数据组时该预设色相为蓝色，即确定在显示第二灰阶数据组时，将预设显示区域内蓝色色相的驱动光源强度设置为0；在显示第三灰阶数据组时，该预设色相为蓝色和绿色，即确定在显示第三灰阶数据组时，将预设显示区域内蓝色和绿色色相的驱动光源强度设置为0。
平均灰阶的最小灰阶对应的色相为蓝色、次小灰阶对应的色相为绿色，因此，该预设显示区域内Ave_Rn，m＝A＞Ave_Gn，m＝B＞Ave_Bn，m＝C。即使该预设显示区域内其它像素单元存在Ri，j，Gi，j，Bi，j像素单元不为Ri，j＞Gi，j＞Bi，j的情况，即原灰阶数据组不符合Ri，j＞Gi，j＞Bi，j的情况，由于该预设显示区域内的平均灰阶Ave_Rn，m＝A＞Ave_Gn，m＝B＞Ave_Bn，m＝C主要显示色为红色，R色相所涵盖的像素单元为多数，少数存在于第二、三灰阶数据组中的B色相，由于B色相的驱动光源强度为0而不显示，因此并不会对于整体画质有太大的影响。
同时，由于预设显示区域内的平均灰阶主要显示色为饱和红色，G、B色相的灰阶相当，其相对于R色相灰阶均相当少，因此可以预测少数存在的第 三灰阶数据组中，G色相驱动光源强度若为0，会使得第三灰阶数据组的G色相少数灰阶不显示，而并不会对于整体画质有太大的影响。
综上，又由于在第二、三灰阶数据组显示时，将预设显示区域内预设色相的驱动光源强度设置为0，即关闭该预设色相的驱动光源，如此可以达到节能的同时也不会对于整体画质造成影响的有益效果。
同理，通过以下方式在第二、三灰阶数据组显示时，将预设显示区域内预设色相的驱动光源强度设置为0，可以达到节能的同时不会对于整体画质造成影响的有益效果。
在一个实施例中，当预设显示区域的平均色相Hn，m满足在3300到300区间且色饱和度属于第一自定义色饱和度范围CTL1～CTH1时，若平均灰阶的最小灰阶对应的色相为绿色、次小灰阶对应的色相为蓝色，则在显示第二灰阶数据组时该预设色相为绿色，即确定在显示第二灰阶数据组时，将预设显示区域内绿色色相的驱动光源强度设置为0；在显示第三灰阶数据组时，该预设色相为蓝色和绿色，即确定在显示第三灰阶数据组时，将预设显示区域内蓝色和绿色色相的驱动光源强度设置为0。

在一个实施例中，当预设显示区域的平均色相Hn，m满足在1500到2100区间且色饱和度属于第四自定义色饱和度范围CTL4～CTH4时，若平均灰阶的最小灰阶对应的色相为蓝色、次小灰阶对应的色相为红色，则在显示第二灰阶数据组时该预设色相为蓝色，即确定在显示第二灰阶数据组时，将预设显示区域内蓝色色相的驱动光源强度设置为0；在显示第三灰阶数据组时，该预设色相为蓝色和红色，即确定在显示第三灰阶数据组时，将预设显示区域内蓝色和红色色相的驱动光源强度设置为0。
在一个实施例中，当预设显示区域的平均色相Hn，m满足在1500到2100区间且色饱和度属于第四自定义色饱和度范围CTL4～CTH4时，若平均灰阶的最小灰阶对应的色相为红色、次小灰阶对应的色相为蓝色，则在显示第二灰阶数据组时该预设色相为红色，即确定在显示第二灰阶数据组时，将预设显示区域内红色色相的驱动光源强度设置为0；在显示第三灰阶数据组时，该预设色相为红色和蓝色，即确定在显示第三灰阶数据组时，将预设显示区域内红色和蓝色色相的驱动光源强度设置为0。

在其中一个具体示例中，由于预设显示区域内的像素单元存在以下两种实施例，因此确定在显示第二、三灰阶数据组时，将预设显示区域内预设色相的驱动光源强度设置为0。
实施例一：
一预设显示区域内各色相的平均灰阶分别为：Ave_Rn，m＝A，Ave_Gn，m＝B，Ave_Bn，m＝C，其中，A＞B＞C，属于红色色相组合。当预设显示区域存在有与平均灰阶的大小顺序不同的像素单元，如一像素单元的原灰阶数据组中各色相的灰阶为Ri，j＝A2，Gi，j＝B2，Bi，j＝C2，是B2＞C2＞A2的绿色色相组合。而将该原灰阶数据组分解为3个灰阶数据组，分别为第一灰阶数据组(R1i，j，G1i，j，B1i，j)、第二灰阶数据组(R2i，j，G2i，j，B2i，j)及第三灰阶数据组(R3i，j，G3i，j，B3i，j)。第一、二、三灰阶数据组满足R1i，j+R2i，j+R3i，j＝Ri，j，G1i，j+G2i，j+G3i，j＝Gi，j，B1i，j+B2i，j+B3i，j＝Bi，j。其中R1i，j，G1i，j，B1i，j均为采用该像素单元原灰阶数据组的最小灰阶Ri，j，即R1i，j＝A2，G1i，j＝A2，B1i，j＝A2。第二灰阶数据组各色相的灰阶则为原灰阶数据组(Ri，j，Gi，j，Bi，j)与第一灰阶数据组(R1i，j＝A2，G1i，j＝A2，B1i，j＝A2)的灰阶差值或灰阶差值共同灰阶，需要说明的是，在灰阶差值为0时，该色相的灰阶为0，在灰阶差值不为0时，该色相的灰阶是不为0的灰阶差值的共同灰阶；共同灰阶是指两个灰阶差值的共同部分，即等于各个非零的灰阶差值中的较小者。即R2i，j＝0，G2i，j＝C2-A2，B2i，j＝C2-A2。第三灰阶数据组为原灰阶数据组与灰阶和值的差值，即R3i，j＝0，G3i，j＝B2-C2，B3i，j＝0。
实施例二：
假设预设显示区域各色相的平均灰阶为：Ave_Rn，m＝A，Ave_Gn，m＝B，Ave_Bn，m＝C，该预设显示区域为A＞B＞C的红色色相组合。因此，该预设显示区 域内的大多数像素单元均满足Ri，j＞Gi，j＞Bi，j，如一像素单元对应的原灰阶数据组(Ri，j＝A1，Gi，j＝B1，Bi，j＝C1)其中，A1＞B1＞C1，该原灰阶数据组的最小灰阶为C1，因此分解成的第一灰阶像素组的各色相的灰阶均为C1；第二灰阶数据组蓝色色相的灰阶为0；因此，可以在该预设显示区域内在显示第二灰阶数据组时的蓝色色相的驱动光源强度设置为0，如将该预设显示区域内在显示第二灰阶数据组时B色相的LED光源关闭，这样可以节约能源。
虽然该预设显示区域内不满足Ri，j＞Gi，j＞Bi，j的像素单元的数量较少，但也必然存在少量如情况1的Ri，j＝A2，Gi，j＝B2，Bi，j＝C2的像素单元，其中B2＞C2＞A2，此时，对于第二灰阶数据组中的B2i，j＝C2-A2灰阶无法正常呈现。同理，在第三灰阶数据组显示时的G、B色相的驱动光源强度设置为0，如G、B色相的LED光源关闭，这样会使得该分预设显示区域内的像素单元与平均灰阶的大小顺序不同时，上述情况1中的Ri，j＝A2，Gi，j＝B2，Bi，j＝C2的绿色色相组合(B2＞C2＞A2)，其第三灰阶数据组的G3i，j＝B2-C2灰阶无法透过G色相的LED光源正常呈现。
在其中一实施方式中，将原灰阶数据组分解成第一灰阶数据组、第二灰阶数据组及第三灰阶数据组的步骤之后，还包括：
S180：获取原灰阶数据组的原显示时长。
S190：在原显示时长内，连续显示第一灰阶数据组、第二灰阶数据组及第三灰阶数据组。
在本实施例中，将一像素单元对应的原图框的灰阶数据组分解为该像素单元对应的三个图框(第一图框、第二图框及第三图框)的第一灰阶数据组、第二灰阶数据组及第三灰阶数据组，依次在时间上呈现三个图框的组合，也即依次显示第一灰阶数据组、第二灰阶数据组及第三灰阶数据组。将原显示时长分成三个时间段，其中一个时间段显示第一灰阶数据组，一个时间段显示第二灰阶数据组，还有一个时间段显示第三灰阶数据组。优选地，为了保证显示效果，这三个时间段的时间长度相同，即均为原显示时长的1/3。在 该优选实施例中，可以通过将显示器的图框频率需提高3倍的方式来实现。
在其中一实施方式中，获取待显示内容在预设显示区域内的各像素单元的原灰阶数据组的步骤，及获取待显示内容在预设显示区域内的各色相的原光源强度的步骤之前，还包括：
S1A0：将液晶显示器的显示区划分为不少于两个显示区域，并依次将显示区域作为预设显示区域。
可以按照预设顺序依次将各显示区域作为预设显示区域实现液晶显示驱动。预设顺序可以为先进行排序再进行列排序的顺序，也可以为先进行列排序再进行排列的顺序。如此，使得整个液晶显示器的各显示分区都进行液晶显示驱动，从而实现整个液晶显示器的显示驱动。
在其中一实施方式中，根据各像素单元的原灰阶数据组，将原灰阶数据组分解成第一灰阶数据组、第二灰阶数据组及第三灰阶数据组的步骤，包括：
(a)、根据原灰阶数据组的最小灰阶，确定第一灰阶数据组各色相的灰阶。即，将原灰阶数据组的最小灰阶作为第一灰阶数据组各色相的灰阶。
(b)、根据原灰阶数据组及第一灰阶数据组，确定第二灰阶数据组各色相的灰阶为灰阶差值或灰阶差值的共同灰阶；灰阶差值为原灰阶数据组与第一灰阶数据组中色相的灰阶的差值。共同灰阶可以为两个灰阶差值的共同部分等于灰阶差值中的较小值。
(c)、根据原灰阶数据组与灰阶和值确定第三灰阶数据组；灰阶和值为第一灰阶数据组及第二灰阶数据组中色相的灰阶的和。
在本实施方式中，第二灰阶数据组各色相的灰阶为灰阶差值或灰阶差值的共同灰阶，如此，避免第二灰阶数据组中的两个灰阶不为0的色相的灰阶大于预设显示区域的平均灰阶中的最小灰阶，而影响分解后的显示效果，从而达到更佳的减少低灰阶的正视角与侧视角各色相间的亮度差异的效果，达到更佳的低色偏显示的画质呈现效果。
以下给出一个具体示例，当预设显示区域内各色相的灰阶均为Ri，j=100，Gi，j＝80，Bi，j＝40的红色色相组合时。将一像素单元(i，j)对应的原图框的原灰阶数据组分解成该像素单元对应的三个图框(第一图框、第二图框及第三图框)的第一灰阶数据组(R1i，j，G1i，j，B1i，j)、第二灰阶数据组(R2i，j，G2i，j，B2i，j)及第三灰阶数据组(R3i，j，G3i，j，B3i，j)。其中第一灰阶数据组的各色相的灰阶为原灰阶数据组中的最小灰阶，即40，也即R1i，j＝40，G1i，j＝40，B1i，j＝40。第二灰阶数据组的各色相的灰阶为灰阶差值与或灰阶差值的共同灰阶，由于Ri，j-R1i，j＝60与Gi，j-G1i，j＝40的共同灰阶为40，因此，R2i，j＝40，G2i，j＝40，B2i，j＝0；第三灰阶数值组的各色相的灰阶为原灰阶数据组与灰阶和值的差值，即R3i，j＝20，G3i，j＝0，B3i，j＝0。将原灰阶数据组分解成三个灰阶数据组，依序在时间上呈现三个灰阶数据组。亦即需要将原图框信号的原显示时长分成三个相等的时间段，其中一个时间段呈现第一灰阶数据组，一个时间段呈现第二灰阶数据组，还有一个时间段呈现第三灰阶数据组。
假设一像素单元的原灰阶数据组(Ri，j＝100，Gi，j＝80，Bi，j＝40)的正视角相对于全灰阶255的亮度比例为SR％、LG％、MB％，侧视角亮度比例对应为SR’％、LG’％、MB’％，其中SR＞LG＞MB，且SR’＞LG’＞MB’。由于越低灰阶信号的正视角与侧视角亮度比例差异越大，可知SR/MB＞SR’/MB’且LG/MB＞LG’/MB’，如此混色使得主要亮度信号SR在正视角的亮度比例相对于MB差异大，但侧视角时主要亮度信号SR’亮度比例相对于MB’差异小，正视角主色调颜色受到影响而色彩鲜艳度下降。以现行VA显示器光电特性来看，标准的信号对应亮度变化为符合指数幕次2.2的关系式。如，Y＝(X/255)2.2，其中Y为规一化亮度，X为灰阶(优选的灰阶为0至255的8bit信号)，可以通过查表或上述信号对应亮度变化为符合指数幕次2.2的关系式的方式确定：SR％＝13.3％、LG％＝7.4％、MB＝1.7％，SR’％＝39％、LG’％＝34.7％、MB’＝23.1％。
第一灰阶数据组由于灰阶均为40，可以通过查表的方式确定第一图框各色相正视角亮度比例分别为1.8％、1.8％、1.8％，侧视角亮度比例分别为17％、17％、17％。对于第二灰阶数据组(R2i，j＝40，G2i，j＝40，B2i，j＝0)，可以通过 查表的方式确定第二图框各色相正视角亮度比例分别为1.8％、1.8％、0％，侧视角亮度比例分别为17％、17％、0％。对于第三灰阶数据组(R3i，j＝20，G3i，j＝0，B3i，j＝0)，可以通过查表的方式确定第三图框各色相正视角亮度比例分别为0.5％、0％、0％，侧视角亮度比例分别为9％、0％、0％。
由于侧视角图框1、2、3的组合在Ri，j、Gi，j、Bi，j各色相上的综合亮度比例分别为17％+17％+9％＝43％，17％+17％+0％＝34％，17％+0％+0％＝17％；而原图框侧视角Ri，j、Gi，j、Bi，j各色相亮度比例分别为40％，33％，17％，可见，主色调R相对于低灰阶的B的亮度比例的比值由原图框40％/17％＝2.35提升为组合图框的43％/17％＝2.53，使得侧视角较接近正视角主色调呈现。需要说明的是，主色调为像素单元对应的原灰阶数据组中最大灰阶对应的色相。
