Spectral simulation of the color-stimuli of the LCD displays without spectrophotometrical measuring

Liquid crystal display technology requires the spectral power distribution measurement of the displayed RGB colors. Such measurement tasks are typically resolved by means of spectrophotometers and the measured data is used in several applications. The costs of color management methods have been decreasing recently mainly because of the reduced costs of spectrophotometric equipment. However the hardware costs are still the limit for a general use. Our intention was to develop a method to enable the determination of spectral power distribution with basic photometry without the use of costly spectrophotometers.
