Color of industrial displays

In some industrial applications, special color information is more important than text or numbers, and it is crucial to use the measured color as a percentage of NTSC color saturation for comparison. In LCD products, color saturation is completely dependent on the influence of backlight. CCF (cold cathode fluorescent screen) backlight is a very popular technology and can achieve 70% and 80% of NTSC color saturation.
In some applications, this range is still not wide enough, and sometimes the range that needs to be achieved is close to 100% of NTSC color saturation. This full-color saturation is usually achieved using LED backlighting in LCD products.
