    Abstract: The present invention provides a transparent electroluminescent device (30) having an optical interference member (50) which reduces the overall reflectance from the device. The optical interference member (50) is formed on a substrate (70), typically comprising a reflective layer (66), a transparent layer (62), a semi-transparent layer (58) and an anti-reflective coating (54). The optical interference member (50) can then be affixed behind the electroluminescent display (31) with a transparent rear electrode (38). When affixed, the optical interference member (50) can reduce reflectance from ambient light and serve as a passivation layer that protects the elements of the electroluminescent device (31) from exposure to external elements. The optical interference member (50) can increase the reflectance of infra-red ambient light, compared to absorbing films, to thus reduce the overall heating of the display. Furthermore, the optical interference member (50) can absorb light emitted towards the back of the display from the electroluminescent layer (31), thus reducing pixel blooming and improving the overall characteristics of the device. In an other embodiment of the invention, the passivation layer can be added without the optical interference layer.

    Abstract translation: 本发明提供一种具有光学干涉构件（50）的透明电致发光器件（30），该光学干涉构件（50）降低了该器件的整体反射率。 光学干涉构件（50）形成在通常包括反射层（66），透明层（62），半透明层（58）和抗反射涂层（54）的基板（70）上。 光学干涉构件（50）然后可以用透明的后电极（38）固定在电致发光显示器（31）的后面。 当固定时，光学干涉构件（50）可以减少环境光的反射率，并且用作保护电致发光器件（31）的元件免于暴露于外部元件的钝化层。 与吸收膜相比，光学干涉构件（50）可以增加红外环境光的反射率，从而减少显示器的整体加热。 此外，光学干涉构件（50）可以从电致发光层（31）吸收朝向显示器的背面发射的光，从而减少像素开花并提高器件的整体特性。 在本发明的另一实施例中，可以不加光学干涉层来添加钝化层。
