Problems solved by technology

In addition, materials such as phosphor powder, luminescent glass, and luminescent film can be used as luminescent materials in field emission devices, but they all have the essential problem of low luminous efficiency, which greatly limits the application of field emission devices, especially in lighting. field application
In addition, in the process of emitting light from the glass light-emitting element, under the irradiation of cathode rays, charge accumulation is gradually formed to negatively charge the surface of the luminescent glass and form a negative potential. Once the surface of the luminescent glass forms a negative potential, the cathode ray will be subjected to a negative electric field effect, affecting its reach to the surface of the light-emitting substrate, which will reduce the luminous efficiency of the field emission device
