ORGANIC ELECTRONIC DEVICE HAVING LOW BACKGROUND LUMINESCENCE

摘要

An organic electronic device has an improved contrast ratio by lowering background luminescence from ambient radiation source(s). Background luminescence may be lowered by increasing absorption of ambient radiation, by reducing reflection of ambient radiation, or a combination of the two. Lower background luminescence can be achieved by using one or more black layers or lattices that are incorporated within the organic electronic device. Also, a large number of materials can be used for high absorbance layers. A change in materials for the electronic device may not be needed, and therefore, new material compatibility issues may not arise. Further, from an electronic performance standpoint, some layers may not be too sensitive to thickness and a plurality of narrow ranges of thicknesses may be used for a layer to allow a layer to have the proper electrical and optical properties. The embodiments obviate the need for a circular polarizer.
