具体实施方式
在一个实施例中，如图1所示，一种显示器Gamma参数的确定方法，包括以下步骤：
S110，设定显示器的亮度。
当显示器的亮度改变时，显示器的Gamma值也应当相应的改变，才能达到最佳的显示效果。在本实施例中，通过使用不同的Gamma值对显示的画面进行校正，从而选择出该亮度对应的最佳Gamma参数。
S120，在该亮度下点亮渐变三基色标准图片。
如图2a-2c所示，渐变三基色标准图片为将红(图2a)、绿(图2b)、蓝(图2c)三种颜色中的每一种按亮度为0-255依次带状排列的图片。在本实施例中，渐变三基色图片在不同的Gamma值下校正。通过记录不可见渐变线的条数来记录显示的效果。当需要使用预设的显示效果时，只需要选取相关的不可见的渐变线条数所对应的Gamma值即可。
在一个具体的实施例中，如图3所示，在该亮度下点亮渐变三基色标准图片包括：
S122，确定各像素的灰阶亮度。
渐变三基色标准图片本身就是像素的灰阶从0至255依次带状排列的图片，使用渐变标准三基色图片能充分体现显示器对颜色的分辨率。
S124，根据灰阶亮度确定灰阶电压。
将像素的灰阶亮度转化为灰阶电压，使得显示器能够对图片进行显示。
S126，根据灰阶电压进行程序编译烧录。
显示控制电路一般都是由专门的芯片驱动控制的，需要根据像素的灰阶电 压对驱动程序进行编译和烧录。
S128，根据程序点亮渐变三基色标准图片。
通过编译的程序将各灰阶电压施加给显示器便能够实现显示器的显示。对显示器的点亮通常可以采用矩阵扫描驱动电路方法。矩阵扫描驱动电路中包含行电极和列电极，行电极就是把水平一组像素的背电极都连接在一起，列电极就是把纵向一组像素的段电极都连在一起。对于某一行发光像元，将需要发光的相应的列都加上正电极，不需要发光的像元的列都接地。当该行电极接地时，则该行上对应的列加正极的像元都发光，而对应列接地的像元都不发光。这种方法类似于CRT的光栅扫描法，循环的给行电极加选择脉冲，同时给列电极加相应的选择或非选择的驱动脉冲，从而实现某行所有显示像素的显示功能。
S130，使用多个不同的Gamma值对渐变三基色标准图片的显示进行校正。
由于显示器的特殊的光电效应，显示器的输入和输出信号具有非线性的关系。若显示器的输出光信号强度为L，输入电压为U，则它们之间的关系为：L＝kUγ，其中k为常数，γ为显示器的Gamma值，该非线性关系称为显示器的Gamma校正。若不对显示器的输入电压和输出光信号强度进行校正，输出图像的亮度和色度将会出现严重的失真。
S140，根据校正结果获取该亮度对应的三基色的最佳Gamma参数。
Gamma校正是实现图像尽可能反映原物体或原图像视觉信息的重要过程。使用不同的Gamma值进行校正能够实现不同的显示效果。根据Gamma校正的结果可以结果获取该亮度对应的三基色的最佳Gamma参数。
在一个具体的实施例中，如图4所示，根据校正结果获取该亮度对应的三基色的最佳Gamma参数的步骤包括：
S142，在每一Gamma值下记录渐变三基色标准图片中不可见渐变线的条数。
在渐变三基色标准图片中不可见渐变线的条数越少，那么显示器对每种颜色的分辨范围会越广，三种颜色的所组合成的颜色范围也会越广。显示器的显示效果也同不可见渐变线的条数相关，一般的可以人工记录下显示效果最佳时对应的不可见渐变线的条数作为显示器显示的参考。
S144，根据预设的不可见渐变线的条数确定三基色的最佳Gamma参数。
根据预设的不可见渐变线的条数确定三基色的最佳Gamma参数具体为将渐变三基色标准图片中不可见渐变线的条数等于预设的不可见渐变线的条数所对应的三基色的Gamma值设为三基色的最佳Gamma参数。
显示器的显示效果是人工确定的，记录下显示效果最佳时对应的不可见渐变线的条数。将该不可见渐变线的条数作为预设的不可见渐变线的条数。通过该预设的不可见渐变线的条数便可以确定不同的亮度所对应的三基色的最佳Gamma参数。不可见渐变线的条数可以由人来确定，当然，为了避免人的个体差异，可以通过图像分析来确定其中不可见渐变线的条数。
S150，将该亮度对应的三基色的最佳Gamma参数存储在显示器芯片中。
最后得到在该亮度下，红色、绿色、蓝色三种颜色的最佳Gamma参数，此数据存放在显示器芯片中。在使用中，当显示器的亮度改变时，通过显示器芯片获取当前亮度对应的最佳Gamma参数，使用该Gamma参数对显示器的显示进行校正，就能实现显示器的最佳显示效果。
上述显示器Gamma参数确定方法使用多个不同的Gamma值对所述渐变三基色标准图片的显示进行校正，能够根据不同的校正结果获取最佳的显示效果；根据校正结果获取所述亮度对应的三基色的最佳Gamma参数，所述三基色的最佳Gamma参数代表了最佳显示效果，通过最佳Gamma参数对显示器的显示进行校正，能够提升画质，充分展现显示器的优质画面。
上述显示器Gamma参数的确定方法根据渐变三基色标准图片中不可见的渐变线的数目，确定显示器的亮度所对应的最佳Gamma参数；该不可见渐变线的条数代表了最佳显示效果，通过该最佳Gamma参数的对显示器的显示进行校正，能够提升画质，充分展现显示器的优质画面。
在具体的实施例中，如图5所示，其中横坐标代表输入信号的强度，纵坐标是输出光强。在250cd/m2的亮度下，有源矩阵有机发光显示器在红、绿、蓝三种颜色的Gamma值为1.8，分别记录红、绿、蓝基色渐变线不可见的渐变线数目。同样在红、绿、蓝三种颜色的Gamma值分别为1.9、2.0、2.1、2.2、2.3、2.4、2.5时，分别记录红、绿、蓝基色渐变线不可见的渐变线数目。图5中从上到下的曲线对应的Gamma值分别为1.8、1.9、2.0、2.1、2.2、2.3、2.4和2.5。
如图6所示，其中横坐标代表输入信号的强度，纵坐标是输出光强。在300cd/m2的亮度下，有源矩阵有机发光显示器在红、绿、蓝三种颜色的Gamma值为1.8，分别记录红、绿、蓝基色渐变线不可见的渐变线数目。同样在在红、绿、蓝三种颜色的Gamma值分别为1.9、2.0、2.1、2.2、2.3、2.4、2.5时，分别记录红、绿、蓝基色渐变线不可见的渐变线数目。图6中从上到下的曲线对应的Gamma值分别为1.8、1.9、2.0、2.1、2.2、2.3、2.4和2.5。
如图7所示，其中横坐标代表输入信号的强度，纵坐标是输出光强。在350cd/m2的亮度下，有源矩阵有机发光显示器在红、绿、蓝三种颜色的Gamma值为1.8，分别记录红、绿、蓝基色渐变线不可见的渐变线数目。同样在红、绿、蓝三种颜色的Gamma值分别为1.9、2.0、2.1、2.2、2.3、2.4、2.5时，分别记录红、绿、蓝基色渐变线不可见的渐变线数目。图7中从上到下的曲线对应的Gamma值分别为1.8、1.9、2.0、2.1、2.2、2.3、2.4和2.5。
如图8所示，其中横坐标代表输入信号的强度，纵坐标是输出光强。400cd/m2的亮度下，有源矩阵有机发光显示器在红、绿、蓝三种颜色的Gamma值为1.8，分别记录红、绿、蓝基色渐变线不可见的渐变线数目。同样在红、绿、蓝三种颜色的Gamma值分别为1.9、2.0、2.1、2.2、2.3、2.4、2.5时，分别记录红、绿、蓝基色渐变线不可见的渐变线数目。图8中从上到下的曲线对应的Gamma值分别为1.8、1.9、2.0、2.1、2.2、2.3、2.4和2.5。
如图9所示，其中横坐标代表输入信号的强度，纵坐标是输出光强。在450cd/m2的亮度下，有源矩阵有机发光显示器在红、绿、蓝三种颜色的Gamma值为1.8，分别记录红、绿、蓝基色渐变线不可见的渐变线数目。同样在红、绿、蓝三种颜色的Gamma值分别为1.9、2.0、2.1、2.2、2.3、2.4、2.5时，分别记录红、绿、蓝基色渐变线不可见的渐变线数目。图9中从上到下的曲线对应的Gamma值分别为1.8、1.9、2.0、2.1、2.2、2.3、2.4和2.5。
可以理解上述显示器的亮度的范围的取值并不局限于250cd/m2至450cd/m2之间，亮度取值的间隔可以更加精细。上述Gamma值的范围并不局限于1.8至2.5，Gamma值的间隔也可以更小。
如图10a和图10b所示，根据显示效果可以确定在某个亮度下，红、绿、蓝三种颜色的最佳Gamma参数。例如，以6条渐变线不可见为基准，在亮度为250cd/m2时，选择R基色的Gamma＝2.5、G基色的Gamma＝2.5、B基色的Gamma＝2.6。在亮度为300cd/m2时，选择R基色的Gamma＝2.4、G基色的Gamma＝2.4、B基色的Gamma＝2.5。在亮度为350cd/m2时，选择R基色的Gamma＝2.1、G基色的Gamma＝2.1、B基色的Gamma＝2.3。在亮度为400cd/m2时，选择R基色的Gamma＝2.0、G基色的Gamma＝2.0、B基色的Gamma＝2.2。在亮度为450cd/m2时，选择R基色的Gamma＝1.9、G基色的Gamma＝1.9、B基色的Gamma＝1.9。
可以理解，上述预设的不可见渐变线的条数不一定为6条，将预设的渐变 线的条数设为不同的值将达到不同的显示效果，可以根据客户需要的显示效果而将不可见渐变线的条数设为不同的值。
最后将上述不同亮度、不同Gamma值所对应的有源矩阵有机发光显示器红、绿、蓝基色渐变线不可见的渐变线数目存储在在显示器芯片中。用户使用中做亮度调节时，能够根据亮度获取相应的三基色的最佳Gamma参数，从而达到有源矩阵有机发光显示器最佳显示效果。
