附图说明
此处的附图被并入说明书中并构成本说明书的一部分，示出了符合本公开的实施例，并与说明书一起用于解释本公开的原理。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
蓝光波长属于可见光波长，同时是RGB色域的蓝色颜色通道，对于这个波长的光的调整会影响到视觉体验。而紫外线是非可见光，完全清楚亦不会影响显示效果。本公开可通过对液晶屏的结构进行改进以降低紫外线和降低蓝色光强度，达到保护眼睛的目的。
典型的液晶屏结构最底层是背光光源，两层偏光片中间是液晶层。液晶分子受电压控制，呈现0到90度的弯曲效果，实现不同的光通过量。
由于紫外线对于显示没有任何效果，所以可以在结构设计上，直接添加一层紫外滤光片实现过滤紫外线的目的。
图1是根据一示例性实施例示出的液晶屏的结构图，如图1所示，液晶屏10包括位于背光光源11之上的下偏光片12、液晶层13和上偏光片14，所述液晶层13位于所述上偏光片14和下偏光片12之间，所述液晶屏10还包括：
位于液晶层13和下偏光片12之间的滤光片15，所述滤光片15用于过滤紫外线，或所述滤光片15用于过滤像素的蓝色分量，或所述滤光片15用于过滤紫外线和所述像素的蓝色分量。
本实施例中，可以使用滤光片实现削弱紫外线和/或蓝光分量的目的。这样，通过物理实现，避免了额外的功耗。
可选的，滤光片15和下偏光片14为一体。由于新增了一层，会导致液晶屏的厚度增加，可以通过改进制造工艺，通过偏光片一层同时实现偏光和过滤紫外线两种功能。
本公开还可以通过颜色转换实现降低蓝光分量。由于蓝色光的调整直接影响了用户的视觉体验，所以通过软件的调节更适用于通用场景的移动设备。
图2是根据一示例性实施例示出的一种颜色调整方法的流程图。如图2所示，该颜色调整方法用于终端中，包括以下步骤：
在步骤S21中，获取像素的当前色域模式；
在步骤S22中，将像素的当前色域模式转换为预设色域模式，得到预设色域模式下像素的蓝色分量；
在步骤S23中，对预设色域模式下蓝色分量进行弱化调节。
例如，在图像渲染流程过程中，需要将像素色域由线性RGB色域模式转换为sRGB(standard Red Green Blue)色域模式，可以对线性RGB色域模式的每个颜色通道分别做非线性(GAMMA)校正，对校正后的蓝色分量进行弱化。
本实施例中，通过上述方式实现弱化蓝光，保护屏幕使用者视力；另外，用户可以根据自身需要在特定情况下开启或关闭调整屏幕颜色的功能，使用灵活方便，用户体验度更好。
可选的，步骤S22包括：
根据以下公式对所述像素的蓝色进行非线性校正，得到所述预设色域模式下像素的蓝色分量：
当CsB大于第一预设值时，CsB＝(1+a)·ClB 1/x；
当CsB小于等于第一预设值时，CsB＝b·ClB；
其中，ClB为当前色域模式下的蓝色分量，0≤ClB≤1；CsB为预设色域模式下的蓝色分量，0≤CsB≤1；a为第一预设非线性校正权值，b为第二预设非线性校正权值；x为所 述非线性校正的第一gamma值。
例如，线性RGB色域模式的蓝色分量的范围为[0，1]。对线性RGB色域模式的蓝色分量进行GAMMA2.2校正，即x＝2.2。
当ClB≤0.00304，则CsB＝12.92·ClB；
当ClB>0.00304，则CsB＝(1+0.055)·ClB 1/2.2。
经过GAMMA2.2矫正的CsB的范围为[0，1]。
可选的，步骤S23包括：
当蓝色分量CsB大于第一预设值时，调整所述第一预设非线性校正权值a至约等于0。
例如，当用户打开护眼模式后，对蓝色通道做特殊处理，通过修改参数：a≈0，实现弱化蓝色分量，弱化蓝光的效果。
可选的，所述方法还包括：
根据以下公式对所述像素的红色和绿色进行非线性校正，得到所述预设色域模式下像素的红色和绿色分量：
当CsRG大于第一预设值时，CsRG＝(1+a')·ClRG 1/y；
当CsRG小于等于第一预设值时，CsRG＝b'·ClRG；
其中，ClRG为当前色域模式下的红色或绿色分量，0≤ClRG≤1；CsRG为预设色域模式下的红色或绿色分量，0≤CsRG≤1；a'为第三预设非线性校正权值，b'为第四预设非线性校正权值；y为非线性校正的第二gamma值，且y<x。
例如，还可以只对红色和绿色分量进行GAMMA2.2校正，然后单独对蓝色分量进行GAMMA2.4或者GAMMA2.6校正。
如图3所示，从GAMMA校正曲线，可以看出，在可选方案中，通过对红绿分量和蓝色分量分别进行不同的GAMMA校正，能够实现弱化蓝光的目的。
另外，由于像素的颜色是由R、G、B三基色按不同的比例混合而成。上述方法主要是通过对B颜色通道进行削弱实现降低蓝光的目的，还可以采用新的三原色，即通过把红绿蓝三原色映射到青(Cyan)、品红(Magenta)、黄(Yellow)三原色坐标，实现颜色混合，避免蓝光对眼睛的伤害。
图4是根据另一示例性实施例示出的一种颜色调整方法的流程图，如图4所示，可选的，所述方法为：
在步骤S41中，获取像素的三原色的映射参数；
在步骤S42中，根据映射参数，将像素当前的三原色映射为新的三原色；
在步骤S43中，根据新的三原色在屏幕上显示图像。
例如，可以通过以下公式进行像素三原色映射，
Figure PCTCN2015093413-appb-000001
在可选方案中，通过对像素的三原色进行调整，以实现减弱蓝光的目的。
