Abstract

The invention provides a transparent conductive glass and a preparation method thereof. The transparent conductive glass comprises a conductive glass substrate and a transparent film formed on the surface of the conductive glass substrate; wherein the surface of the transparent film is provided with a plurality of grooves; and the transparent film is made of optical resin. In the transparent conductive glass, a transparent film is formed on the surface of the conductive glass substrate, and a plurality of grooves is formed on the surface of the transparent film, thus the roughness of the conductive glass substrate is increased, so that the total reflection rate of the light that is incident on the conductive glass substrate is reduced, the transmittance of the light is increased, and finally the overall luminous efficiency of positive pole is improved.

Description

technical field [0001] The invention relates to the field of field emission devices, in particular to a transparent conductive glass and a preparation method thereof. Background technique [0002] The field emission device is a new type of light source. In a vacuum environment, the electrons emitted by the electron emitter on the cathode plate are accelerated by the positive voltage on the anode plate and then bombarded on the phosphor on the anode plate to emit light. Field emission light sources can achieve uniform, thin, and surface light emission, and have been widely used in displays, lighting equipment, and microwave components, and have great application potential. [0003] The anode plate is an important part of the field emission device, which includes a conductive glass substrate, a phosphor layer, a dielectric layer, and a reflective layer from top to bottom. The electrons bombard the phosphor layer to emit light, and the light is transmitted through the conducti...
