| Abstract |
In this paper, organic dispersion type back light EL(Electroluminescent) devices were manufactured using Ethyl hydroxy ethyl cellulose as organic binder, ZnS:Cu as phosphor powder and BaTiO₃ as dielectrics by screen printing method, which are focused on as a new light source. The properties of the fabricated organic dispersion type back light EL devices were showed 1.98[mA/㎡]of current density, 0.075[W] of power consumption, 7.1[nF] of capacitance at 25[℃], 100[V], 400[Hz], repectively. Also brightness of the fabricated device was revealed 20～110[cd/㎡] at 50～150[V] and the change of color was showed bluish green of x=0.1711, y=0.3676 which are color coordinate by CIE. |
