步骤101：获取原始画面每一像素的M基色输入信号，所述原始画面包括分别与所述多个像素单元相对应的多个像素，所述多个像素中的每个像素使用M种基色显示彩色图像，M为大于1且小于N的整数；以及
步骤102：根据所述N基色显示屏每一基色的色坐标和所述M基色输入信号计算得到所述N基色显示屏对应像素单元的N基色输入信号。
本实施例中，获取原始画面每一像素的M基色输入信号，根据N基色显示屏每一基色的色坐标和M基色输入信号计算得到N基色显示屏对应像素单元的N基色输入信号，从而能够实现由三基色输入信号得到四基色、五基色甚至六基色输入信号，并且相比于传统的三基色显示屏，由于本公开实施例提供的N基色显示屏可以利用更多的基色显示画面，从而能够提高显示画面的色域，增强显示效果。
