Abstract: Disclosed are a single-pixel single-colour display and signal receiving module and a device containing the module. First, a combination of a group of lens and mixed-colour screens is used to condense light rays emitted from a colour light source through a light condensation sheet; then, a refraction colour-collection sheet containing a group of curved surfaces is used to refract each condensed light ray on the mixed-colour screens at the same location, so as to synthetize a single colour, so that even though each changed pixel is viewed after being amplified, one pixel and one colour instead of one pixel and three colours can be observed. The present invention changes the display concept of the past, and reduces the physiological problems affecting the eyes and head because of fuzzy processed colour. Meanwhile, under a micronization process, a display device is enabled to display a more realistic effect, so that the original combined colour cannot be seen any longer. The present invention also can be used for transmitting or receiving invisible electromagnetic wave signals, and can be used for receiving the electromagnetic wave signals of the other wave band simultaneously during display.

The method comprises: loading, in an optical signal at a sending end, wavelength label frequency and attribute information of a channel for transmitting the optical signal; sending the wavelength label frequency and/or the attribute information; a detection end receiving the optical signal and acquiring, from the optical signal, the wavelength label frequency and/or the attribute information of the channel for transmitting the optical signal; and monitoring the ROADM optical network according to the wavelength label frequency and/or the attribute information. The present invention solves the technical problem in the prior art that the ROADM optical network cannot be effectively monitored, thereby achieving the technical effect of effectively monitoring the ROADM optical network.
