其中，所述驱动模块中预先存储有目标帧图像的显示数据。例如，所述驱动模块中可以设置存储器，用于预先存储目标帧图像的显示数据。当然，所述显示面板的显示画面可以包括多个帧，所述驱动模块中也可以预先存储所述显示面板的全部帧的显示数据。
进一步地，所述显示面板的目标帧图像包括多个像素点，其中，至少一个像素点预设有与该像素点对应的灰阶。所述目标帧图像的显示数据可以用一维数组或多维数组表示，数组中的每个元素可以与显示画面的每个像素点相对应，用于驱动所述显示面板中每个像素按照预设的灰阶进行显示。可以理解，本申请对于显示数据如何表示并不限定。
进一步地，所述目标帧图像的灰阶数据可包括第一灰阶极值以及第二灰阶极值。在本申请实施例中，所述目标帧图像的第一灰阶极值可以是该目标帧图像的多个第一灰阶的最大值，所述目标帧图像的第二灰阶极值可以是该目标帧图像的多个第二灰阶的最大值。
进一步地，根据目标帧图像的显示数据得到目标帧图像的灰阶数据，包括：
步骤S101：根据目标帧图像的显示数据得到目标帧图像的第一灰阶极值；
进一步地，所述第一灰阶可以是预先设置的灰阶，所述目标帧图像的显示数据可以包括多个所述第一灰阶，每个第一灰阶与目标帧图像的一个像素点相对应。例如，所述显示面板的全部帧的显示数据的灰阶可以用8位二进制数字表示，灰阶的表示范围从0至255。对于一帧显示画面而言，该帧显示画面可以包括1024*768个像素，该帧显示画面的各个像素的第一灰阶范围可以是16至128，即对于该帧显示画面而言，该帧显示画面的第一灰阶极值可以是128，即该帧显示画面的最大灰阶。
进一步地，所述目标帧图像可以分为多个显示区域，所述第一灰阶极值为所述多个显示区域中的至少一个显示区域的多个第一灰阶的最大值，所述第二灰阶极值为所述多个显示区域中的至少一个显示区域的多个第二灰阶的最大值。每个显示区域的灰阶的最大值可以不同。因此，所述目标帧图像的第一灰阶极值也可以是该帧图像的一个显示区域中的多个第一灰阶的最大值。例如，所述目标帧图像可以分为两个显示区域。第一个显示区域的第一灰阶范围从16至108，第二个显示区域的第一灰阶范围从32至116，此时，所述目标帧图像的第一灰阶极值可以是第一个显示区域的灰阶的最大值108，也可以是第二个显示区域的灰阶的最大值116。

具体的，所述变换后的多个第二灰阶中每个第二灰阶可以与变换前的一个第一灰阶相对应，也可以与变换前的多个第一灰阶相对应。可以理解，不同的变换方式会在第一灰阶与第二灰阶产生不同的对应关系，本申请对于第一灰阶与第二灰阶的对应关系并不限定。
进一步地，所述第二灰阶极值为目标帧图像的多个第二灰阶的最大值。即，所述第二灰阶极值与所述第一灰阶极值有类似的含义。例如，对于一帧显示画面而言，该帧显示画面可以包括1024*768个像素，该帧显示画面的各个像素的第一灰阶范围可以是16至128，即对于该帧显示画面而言，该帧显示画面的第一灰阶极值可以是128。在对目标帧图像的多个第一灰阶进行变换后，该帧显示画面的各个像素的第二灰阶范围可以是32至216，该帧显示画面的第一灰阶极值可以是216。

步骤S1022：根据所述变换后的多个第二灰阶得到目标帧图像的第二灰阶极值。
其中，对目标帧图像的多个第一灰阶进行变换，得到变换后的多个第二灰阶，可包括：将所述目标帧图像的第一灰阶范围划分为多个子区间；根据所述划分的多个子区间以及预设的变换系数对目标帧图像的多个第一灰阶进行变换，得到变换后的多个第二灰阶。例如，可以将预设的变换系数与所述目标帧图像的多个第一灰阶进行相乘，从而得到多个第二灰阶。
图2示出本申请实施例的灰阶变换前的示意图，图3示出本申请实施例的灰阶变换后的示意图。
如图2和图3所示，横轴可以表示电压，纵轴可以表示灰阶。在图2中，对所述第一灰阶变换前，可以看出所述目标帧图像的第一灰阶的最大值可以对应于第10级伽马电压的电压值；在图3中，对所述第一灰阶变换后，可以看出所述目标帧图像的第二灰阶的最大值可以对应于第1级伽马电压的电压值。即，经过变换后，所述目标帧图像的灰阶的最大值相较于变换前的灰阶的最大值可以更大。
通过使用式(1)中的分段函数进行变换，本申请实施例能够使目标帧画面的灰阶与第一电源电压的电压值相适应，保证调整第一电源电压的电压值后显示画面的质量。
示例性地，步骤S1021可以用式(1)表示如下：

其中，Dinn可表示输入的目标帧图像中第n个像素点变换前的第一灰阶；λ1可表示在输入的目标帧图像中第n个像素点的第一灰阶位于C0至C1范围的情况下，对应于Dinn的系数；λ2可表示在目标帧图像中第n个像素点的灰阶位于C1至C2范围的情况下，对应于Dinn的系数。依次类推，λm可表示在目标帧图像中第n个像素点的灰阶位于Cm-1至Cm范围 的情况下，对应于Dinn的系数。Dout(n)可表示目标帧图像中第n个像素点变换后的第二灰阶。m可以用于表示所述子区间的数量。在一个示例中，C0可以是0，Cm可以是255。
进一步地，将所述目标帧图像的第一灰阶范围划分为多个子区间。例如，对于一帧显示画面而言，该帧显示画面可以包括1024*768个像素，该帧显示画面的各个像素的第一灰阶范围可以是16至128，此时C0可以是16，C1可以是32，Cm可以是126。可以理解，本申请对于如何划分多个子区间以及子区间的数量并不限定。
进一步地，对于所述目标帧图像的至少一个像素点所对应的第一灰阶，可以根据式(1)对该第一灰阶进行变换。例如，可以为该第一灰阶赋予一个变换系数，并将该变换系数与该第一灰阶相乘，从而得到对应于该第一灰阶的第二灰阶。所述变换系数可以预先存储在存储器中。可以理解，本申请对于所述变换系数如何确定并不限定。
通过对将所述目标帧图像的第一灰阶范围划分为多个子区间，并根据所述划分的多个子区间以及预设的变换系数对目标帧图像的多个第一灰阶进行变换，得到变换后的多个第二灰阶，本申请实施例能够灵活配置对目标帧图像的灰阶进行变换，进而能够在不同的应用场景下动态自适应地调整得到第二电源电压的电压值，进一步节省功耗。

进一步地，根据所述第二伽马电压的电压值以及伽马基准电压调整各阶伽马电压的电压值，得到调整后的各阶伽马电压的电压值，可以用式(4)表示如下：
gamma(n)＝f3(gamma_num′,gamma_ref)
其中，gamma_num’表示与目标帧图像的第二灰阶极值相对应的第二伽马电压的电压值；gamma(n)可表示经过调整后的第n阶伽马电压的电压值。
进一步地，根据所述调整后的各阶伽马电压的电压值以及伽马基准电压对预先设置的第一电源电压的电压值进行调整，得到第二电源电压的电压值，可以用公式(5)表示如下：
AVDD′＝f4(gamma(n),gamma_ref)
其中，AVDD’表示对预先设置的第一电源电压的电压值进行调整后得到的第二电源电压的电压值。AVDD’可以大于多个第二伽马电压的电压值中的最大值gamma_max，可以用公式(6)表示如下：
AVDD′＝gamma_max+ΔV
其中，ΔV可以大于0，表示AVDD’与gamma_max之间的差值。ΔV可以根据情况进行确定，本申请并不限定。
需要说明的是，在本申请实施例中，函数f1、f2、f3及f4可以相同，也可以不同。可以理解，在实际应用中，可以根据实际需要配置相应的函数，本申请对于函数f1、f2、f3及f4并不限定。
