Application of Virtual Display Technology of LCD Backlight Spectrum Optimization Algorithm Based on Linear Programming

Abstract

In order to make the color of image display more realistic, optimize the use of energy, and improve the light efficiency of the module through reasonable spectral distribution, this paper proposes a backlight spectral optimization algorithm based on linear programming. With the goal of maximizing the backlight luminous efficiency, the theoretical maximum of the luminous efficiency of the backlight spectrum can be achieved by constructing a linear programming model. The research process is to obtain the optimal distribution of transmittance spectrum by linear programming method on the premise of ensuring the color gamut standard of display system. The results show that the light efficiency can be increased to 335.5 lm/W, while the original light efficiency of the system is less than 150 lm/W. With the goal of maximizing the light efficiency, light sources with narrow bandwidths such as lasers and quantum dot materials can be used to simulate and reconstruct these characteristic wavelengths. There will be easier to approach the ideal optimization spectrum and achieve the theoretical maximum luminous efficiency of 610.8 lm/W.

“…The disadvantage is that the former has a longer execution time, while the experimental analysis of the latter is based on simulation only, lacking verification based on the real dimming system. Cui et al proposed a backlight spectral optimization algorithm based on linear programming, aiming at maximizing the luminous efficiency of the backlight [86]. By constructing a linear programming model, the theoretical maximum value of the spectral luminous efficiency of the backlight can be calculated.…”
