  • Publication number: 20030127972
    Abstract: A dual-panel active matrix organic electroluminescent display comprises an organic electroluminescent display panel, an active matrix panel, and a conducting and adhesive material between these two panels. The organic electroluminescent display panel and the active matrix panel are fabricated separately and then adhered and bonded together. Therefore, the layout portion of a polycrystalline-silicon TFT can be increased. If a heat and pressure adhering method is used to bond the two panels, a transparent light-conducting region is not required for the pixels on the active matrix panel. If a UV light exposure adhering method is used, only a small transparent region is reserved for UV light curing. As a result, the lighting area of the organic electroluminescent display is almost 100%.
