RGGB四基色激光显示系统的研究

为了获得更大的绿色部分色域与超高清显示标准（Rec. 2020）中更高的色域覆盖比例，在三基色的基础上添加了532 nm激光作为第四基色。在CIEL*a*b*立体颜色空间中，系统理论地分析了波长组合为660 nm,532 nm,520 nm,465 nm的红绿绿蓝（RGGB）四基色系统，研究了它在色域体积、色域覆盖率以及在特定颜色区域的颜色渲染能力等方面的表现。结果表明，其色域体积峰值为2218900，与Rec.2020标准的色域覆盖比例最大为97.51%，黄色区域的色域增强峰值为29.75%，绿色区域的色域增强峰值为9.58%; 与红绿蓝（RGB）三基色组合和红绿蓝黄（RGBY）四基色组合相比，RGGB四基色组合在各个参数维度均有优异表现，可以根据性能需求来灵活选择对应的四基色亮度比例。此研究为实际四基色显示系统的搭建提供了理论指导。

Abstract

In order to obtain a larger color gamut in the green region and broader gamut coverage with Rec. 2020, 532 nm laser light was adopted as the fourth primary. The color gamut volume, gamut coverage with Rec. 2020, gamut enhancement in the green region, and gamut coverage in the yellow region of RGGB(red, green, green, blue) wavelength set 660 nm,532 nm,520 nm,465 nm was simulated and analyzed in CIEL*a*b* uniform color space. The result shows that the maximum color gamut volume is 2218900, the maximum gamut coverage with Rec. 2020 standard is 97.51%, and the maximum gamut enhancement in the yellow region and green region is 29.75% and 9.58%, respectively. This RGGB system has excellent performance when compared with RGB three-primary system and RGBY four-primary system, and the luminance ratio can be adjusted according to the actual requirements. This research provides another feasible idea for the construction of a four-primary color display system.
