In this work, we built a multi‐primary display model based on the new quantum dots (QD) technology to enlarge the display color gamut. In this way, first the emission spectral radiance curves of the three RGB channels of a commercial QD display were fitted to a four‐parameter function. From this modeling, it is possible to gain new theoretical color primaries by selecting new spectral peaks (cyan, yellow, magenta, and/or additional RGB primaries) and imposing some colorimetric conditions for the resulting white of this proposed theoretical multi‐primary display. Proper characterization to assess the performance of the display was conducted to know if the basic “gain‐offset‐gamma” (GOG) model can be used for direct and inverse color reproduction (from RGB to CIE‐XYZ, and vice versa). The GOG model was found to well characterize this display. The spatial uniformity of the display was also evaluated in luminance and color chromaticity terms. Finally, with the primaries modeling and color characterization based on the GOG model, a 5‐primary model (RGBYC) was tested. The evaluation of this theoretical RGBYC display model confirms the gamut enlargement, which can also improve goniochromatic color reproduction.

基于量子点显示技术的多原始经验模型

在这项工作中，我们基于新的量子点（QD）技术构建了多基色显示模型，以扩大显示色域。通过这种方式，首先将商用QD显示器的三个RGB通道的发射光谱辐射曲线拟合为四参数函数。通过这种建模，可以通过选择新的光谱峰（青色，黄色，品红色和/或其他RGB原色）并为该拟议的理论上多原色显示的白色施加一些色度条件，从而获得新的理论原色。进行了适当的表征以评估显示器的性能，以了解基本的“增益偏移伽玛”（GOG）模型是否可用于直接和反向颜色再现（从RGB到CIE-XYZ，反之亦然）。发现GOG模型很好地表征了这种显示。还用亮度和色度来评估显示器的空间均匀性。最后，通过基于GOG模型的原色建模和颜色表征，测试了5原色模型（RGBYC）。对这种理论RGBYC显示模型的评估确认了色域的扩大，这也可以改善色差色的再现。
