In consideration of fabrication and cost issue, lately White Organic Light-Emitting Device (WOLED) combined with Color Filter (CF) has become one of promising methods to produce full-color OLED displays. This method adopts the same light source so the lifetime and brightness of Red¡BGreen and Blue emissions are similar and there is no concern for color distortion. In addition, there is no mismatch issue of shadow mask alignment during fabrication. This method not only improve the resolution but also be able to make large size FPD (Flat Panel Displays). In this study, we fabricate White Polymer Light-Emitting Device (WPLED) on custom-built CF, and discuss its full-color characteristics after integration. This study contains four portions: 1.)Fabrication and electro-optical analysis of WPLED on ITO glass 2.)Electro-optical analysis of CF glass 3.)Optical simulation¡GEL(Light-Emitting) spectra of WPLED combined with transmissive spectra of CF 4.)Fabrication and electro-optical analysis of WPLED on CF glass
