Abstract
The utility model relates to a porcelain enamel electroluminescent screen which belongs to alternating-current electroluminescence technology. The utility model discloses the porcelain enamel electroluminescent screen which adopts a metal plate as a basal plate which is sprayed and coated with a glaze, and the surface of the utility model is protected by an enamel layer. The utility model can be used as a vehicle license plate, a road sign displayer and various warning boards.
Description
The invention belongs to the AC electroluminescence technology.
In recent years, A.C. luminous screen has obtained using widely in the demonstration field as the solidification flat device.But in harsher environment, as vibrate greatly, under the conditions such as temperature shock, plastics made from organic media and glass electroluminescence screen just can't operate as normal, and Electroluminescent Plate by Enamelling then demonstrates speciality.
The purpose of this invention is to provide a kind of high brightness, the Electroluminescent Plate by Enamelling of low-power consumption.
For achieving the above object, the technical solution used in the present invention is two interpolars that luminescent material are clipped in the enamel layer that scribbles high-k, and under the AC power effect, two interpolars produce alternating electric field, and luminescent powder is luminous because of the effect that is subjected to this alternating electric field.
The present invention implements like this:
Make the substrate of luminescent screen with sheet metal, spraying titanium white reflection horizon on substrate, calcination, the spraying luminescent layer, calcination, evaporation ito transparent electrode, this electrode and substrate are two electrodes of luminescent screen, spray the enamel protective seam at last, after calcination.
Below in conjunction with drawings and Examples the present invention is described in further detail.
Accompanying drawing 1 is a diagrammatic cross-section of the present invention.
Select 08f hot pressing steel plate for use; make 170 * 240(mm) sizes as substrate (1); clean the back at the one side spraying titanium enamel (2) of substrate as the reflection horizon, 850 ℃ of calcinations 1 minute, spraying luminescence medium glaze (3); 680 ℃ of calcinations 1 minute; evaporation ITO electrode (4) scrapes silver slurry bus-bar (5), enamel protective seam (6) on the ITO electrode; 600 ℃ of calcinations 1 minute are respectively welded out a lead-in wire (7) on substrate and silver slurry.
The present invention is at 175V, and 1000Hz drives down, and brightness can reach 90cd/m
2, static current of lcd 0.4mA/cm
2175V, 400Hz drive down, and brightness can reach 48cd/m
2, static current of lcd 0.18mA/cm
