Patent ID: 8456731

Claim:
An electro-wetting display, comprising: a light guide plate having a light incident surface and a light output surface; a light source, in proximity to the light incident surface of the light guide plate; a transparent electrode layer, disposed on the light output surface of the light guide plate; a dielectric layer, covering the transparent electrode layer, wherein a refractive index of the dielectric layer is n 1 ; a transparent nonpolar solution layer, disposed on the dielectric layer, wherein a refractive index of the transparent nonpolar is n 2 , and n 2 ≧n 1 ; a counter substrate, disposed on the transparent nonpolar solution layer; a light emitting material layer, disposed on the counter substrate; a counter electrode, disposed on the counter substrate; and a transparent polar solution layer, disposed between the light guide plate and the counter substrate, wherein the difference between the refractive index of the dielectric layer n 1 and the refractive index of the transparent nonpolar n 2 is about 0.1 to 1.
