The method of active image quality reconstruction adaptive camouflage based on flexible display technology is to use flexible display devices to combine spectrum transfer technology and active image quality reconstruction technology to achieve the change, transfer and selective distribution of the target surface spectral radiation characteristics. In this design, the optical characteristics of the target could be changed by modulating the optical characteristic parameters of the target surface, and the background image could be captured in real time during the activity of the target and displayed on the flexible display. The use of active image quality reconstruction, flexible display and emissivity control layer achieves the purpose of modulating the infrared radiation intensity of the target and effectively segmenting the target heat map, so as to achieve a high degree of integration with the surrounding natural environment throughout the weather and the whole process, and the spectrum of the target surface. The distribution characteristics do not change with the change of the detection direction, achieve the effect of target camouflage. Compared with the method of changing the physical structure characteristics of the target surface, this technique makes the target environment more adaptable and more survivability, and easy to implement.
