Infrared (IR) display technology implements a display using IR radiation. Whereas ordinary visible displays that output digital data in the visible spectral range are detectable to human eyes, an IR display outputs data outside the visible spectral range. This study looks at the possibility of expanding the color-replication spectrum beyond the visible range by applying IR wavelength separation techniques. We developed a new display technology that uses the same driving method as general display technology but emits IR radiation that cannot be seen by humans. The IR wavelength region was separated into three regions, similar to the RGB regions of visible displays, and an IR display capable of outputting images and movies was produced by combining these IR emissions. The implementation of various characters, figures, and videos was demonstrated. The present method can be applied to the production of single displays based on IR radiation, as well as to the production of multi-displays whereby an IR display is mounted on top of a visible light display on a single device. This technology can be used to provide a smart digital information environment where humans can selectively visualize or conceal information.

红外（IR）显示技术使用IR辐射实现显示。人眼可以检测到在可见光谱范围内输出数字数据的普通可见显示器，而IR显示器则输出可见光谱范围以外的数据。这项研究着眼于通过应用红外波长分离技术将彩色复制光谱扩展到可见范围之外的可能性。我们开发了一种新的显示技术，该技术使用与常规显示技术相同的驱动方法，但是会发出人类无法看到的红外辐射。将IR波长区域分成类似于可见显示器的RGB区域的三个区域，并且通过组合这些IR发射来产生能够输出图像和电影的IR显示器。演示了各种字符，图形和视频的实现。本方法可以应用于基于IR辐射的单个显示器的生产，以及应用于其中将IR显示器安装在单个设备上的可见光显示器之上的多显示器的生产。该技术可用于提供一个智能的数字信息环境，使人们可以选择性地可视化或隐藏信息。
