Design and implementation of special LCD night mode color scheme based on GUI graphical interface

Studying how to quickly and efficiently match LED lights to obtain the standard white light in night mode that required by the national military standard is of great significance to improving the scientific research and production efficiency of special LCD displays. This article designs a visual color matching calculation program by establishing a color matching model and combining it with MATLAB software. Given the initial parameters and target color parameters, the RGB threecolor brightness level that meets the color matching requirements can be automatically generated, thereby completing the color matching needs quickly and efficiently. The experimental results show that, aiming at the standard white light required by the national military standard, the given color matching parameters can achieve white light display very well, and the color coordinate error is within 0.4%, which can meet the needs of engineering practice.
