Thus , two colors which match visually but do not emit equivalent amounts of light , as defined by the bandwidth of the filters , will be recorded differently on the film , and therefore differently on the reproduction 因此，两个视觉匹配但不是反射通过滤色片带宽定义的等量光的两个颜色，在胶片上的记录会有所不同，因而复制出来后也就不同。
This colored background of stn is illcome for people who accustom to black - white display . and from the conditions at present , black - white display is necessary condition to get colored display by insetting filter film Stn的这种彩色背景，不受习惯于tn黑白显示的用户的欢迎；而且从目前的生产过程和生产条件来看，黑白显示是利用嵌镶滤色片作为获得彩色显示的必要条件。
