A novel full-color transparent display screen based on the plasmon resonance and coupling effect of silver nanoparticles is proposed. Firstly, it shows that the optimized silver particles can support three scattering peaks respectively in the red, green and blue wavebands, which can be used to enhance the performance of full-color transparent display. Secondly, It experimentally demonstrates that, through a simple solution thermal method, the optimized silver nanoparticles can be embedded in the transparent matrix material to form a transparent display screen. The projector-to-screen projection test further proves that this screen indeed presents the full-color display with high transparency, high brightness and wide viewing angle. In addition, It also demonstrates that the silver nanoparticles have the dipole-type far-field scattering patterns at the three resonance wavelengths of red, green and blue due to the plasmon resonance and coupling effect, which well explains the reasons of the display screen with high brightness and wide viewing angle. The transparent display screen proposed r with the characteristics of high transparency and brightness, wide viewing angle, simple preparation process and low cost, will have potential applications in the field of transparent display.
