摘要

21世纪初商业显示逐步发展成为一个独立的行业，为了提升广色域全彩Mini-LED商业显示所呈现出的视觉效果，针对当前Mini-LED拼接屏颜色还原效果不佳、色差较大且价格高昂等问题，提出了一种应用于Mini-LED商业显示的色域映射方法。该方法基于Mini-LED的显示特性文件，通过查找表与四面体插值运算对其进行色域映射，再根据Mini-LED拼接屏对不同颜色特征的还原效果与表达能力之间的差异对查找表进行优化，改善了映射精度、映射时间以及资源消耗之间的平衡。实验结果表明：Mini-LED显示在进行色域映射后的最大亮度损失约为3.5%，像素光强均匀性由8.2%降至4.9%，色差由2.2Δ

降至1.3Δ

，证明该方法对全彩Mini-LED商业显示在像素光强均匀性、色差等方面均有较好的矫正效果，同时在视觉观测下的效果也有一定的提升。

Abstract

At the beginning of the 21st century

commercial display has gradually developed into an independent industry. In order to improve the visual effects presented by wide color gamut full-color Mini-LED commercial display

to solve the problems of the poor color reproduction effect

large color difference and high price of the current Mini-LED splicing screen

a color gamut mapping method applied to Mini-LED commercial display is proposed. This method is based on the display characteristic file of Mini-LED

and the color gamut is mapped by the method of look-up table and tetrahedral difference. Then

according to the difference between the reduction effect and expression ability of different color features between Mini-LED splicing screens

the lookup table is optimized

and the balance of the mapping accuracy

mapping time and resource consumption is improved. The experimental results show that the maximum brightness loss of Mini-LED display after color gamut mapping is about 3.5%

and the uniformity of pixel intensity decreased from 8.2% to 4.9%

the color difference is reduced from 2.2Δ

to 1.3Δ

which proves that this method has a good correction effect for the full-color Mini-LED commercial display in pixel intensity uniformity

chromatic aberration and other aspects

meanwhile the effect under visual observation is also improved to a certain extent.
