Problems solved by technology
However, the preparation process of the metal particles and the core-shell structure used is cumbersome and time-consuming, and it is necessary to ensure that the particles are evenly distributed in the matrix, which requires high preparation environment and preparation methods.
Recently, a related patent (CN108997687A) proposes a mixture of several nanoparticles that respond to red, green, and blue colors (limited wavelength bands are 660nm, 560nm, and 450nm) to achieve color transparent display. The same problem is that its use The preparation process of nanoparticles requires measuring instruments to assist in the measurement, and the particle size accuracy is high, so the preparation method is more complicated, and the film is also prepared by coating with a mixed solution, and the preparation cycle is longer

Abstract
The transparent display screen comprises a transparent substrate which is horizontally arranged, and a blue light display metal particle layer, a green light display metal particle layer and a red light display metal particle layer are sequentially arranged on the upper surface of the transparent substrate. The transparent display screen comprises the transparent substrate and the metal nanoparticle layer for realizing strong scattering of red light, green light and blue light, and the metal nanoparticles have wavelength selectivity strong resonance scattering characteristics, so that clear patterns can be displayed on the screen when light near resonance wavelength is projected on the screen. Compared with a previous preparation method based on silver nanoparticle solution coating and drying, the preparation process has the advantages of low cost, short preparation period, convenience in tuning of display wavelength and the like, and has important application value.
Description
Technical field [0001] The present invention belongs to the field of transparent display, and more particularly to a transparent display screen and its production process based on plasma-based granules. Background technique [0002] In recent years, transparent display technology is increasingly focused on people, because of its transparent display panel, it can be used as a head-up display (HUD), head mounted projectiondisplays, HMPD ) And suitable for floating displays on architectural windows and shop window, gradually become the trend of contemporary display technology development. Among them, HUD technology has developed rapidly, in the military field, which can project flight data to the driver's forward transparent display assembly, so that the driver can maintain a flat surface state that does not affect the outside of the cockpit outside, while watching the transparent display panel The navigation data, driving environments, etc. to guide driving. Therefore, there is an ...
