Figure PCTCN2016080809-appb-000006
其中，(Xm,Ym,Zm)为所述全部显示三刺激值中的第m显示三刺激值，所述第m显示三刺激值为所述第m RGB颜色的三刺激值，(Xi,Yi,Zi)为所述第四原始三刺激值，(Xj,Yj,Zj)为所述第五原始三刺激值，(Xk,Yk,Zk)为所述第六原始三刺激值。

具体的，将所述全部显示三刺激值中的共计2563个显示三刺激值依次代入关系式(3)进行计算，然后对全部计算结果取最小值，与此最小值对应的显示三刺激值就是所述校准三刺激值。
本实施例的方法100，在S140中获取所述第二组原始颜色的原始三刺激值时，同时也记录了所述第二组原始颜色与所述第二组原始颜色的原始三刺激值之间的对应关系；在S150中确定所述全部显示三刺激值时，也同时记录了所述第m显示三刺激值、所述第四原始三刺激值、所述第五原始三刺激值以及所述第六原始三刺激值之间的对应关系。因此在S160中计算得到所述校准三刺激值时，能够同时得到与所述校准三刺激值对应的三个原始三刺激值。进一步的，查询出与此三个原始三刺激值对应的所述第二组原始颜色中的三种原始颜色。此三种原始颜色分别与所述校准颜色具有相同R分量灰阶值、G分量灰阶值和B分量灰阶值。由此，在S170中，最终能够确定出所述校准颜色。之后，在S180中，向所述第二LCD发送校准控制信号，所述第二LCD接收所述校准控制信号，所述第二像素单元显示显示出所述校准颜色。
应理解，本发明实施例的方法100，仅以所述第一像素单元和所述第二像素单元为研究对象进行说明。但实际上，本方法100可以同时用于对所述第一LCD和所述第二LCD上的多个对应像素单元进行颜色显示的一致性校准。
