摘要： A display having a plurality of addressable pixels and a method for constructing the same. The display includes a substrate having a first conducting layer thereon. The conducting layer includes a plurality of parallel row electrodes having edges separated by insulating material. A first polymer layer constructed from one or more thin films overlies the parallel row electrodes. An insulating layer overlies the polymer layer, the insulating layer having windows therein defining pixels for the display. The insulating layer overlies the edges of the row electrodes while providing access to the first polymer layer in the area of the pixels. A second conducting layer overlies the insulating layer and includes a plurality of separated column electrodes. Each column electrode crosses a plurality of the row electrodes and is located over the windows in the insulating layer at points defining the pixels. The second conducting layer is preferably constructed by depositing a layer of photoresist over the insulating layer and patterning the layer of photoresist to provide openings extending therethrough. The openings are wider in the portion of the layer nearest to the insulating layer. This layer acts as a shadow mask for depositing a layer of conducting material. In one embodiment of the invention, a second polymer layer is located between the insulating layer and the second conducting layer. The insulating layer is preferably constructed from a layer of photoresist that is baked to cross-link the photoresist. The polymer layers include an electroluminescent material, which is preferably based on a polyfluorene.
摘要翻译：具有多个可寻址像素的显示器及其构造方法。显示器包括其上具有第一导电层的基板。导电层包括多个平行的行电极，其边缘由绝缘材料分开。由一个或多个薄膜构成的第一聚合物层覆盖在平行行电极上。绝缘层覆盖聚合物层，绝缘层上具有窗口，用于显示器的像素。绝缘层覆盖行电极的边缘，同时提供对像素区域中的第一聚合物层的访问。第二导电层覆盖绝缘层并且包括多个分离的列电极。每个列电极与多个行电极交叉，并且在限定像素的点处位于绝缘层中的窗口上方。第二导电层优选通过在绝缘层上沉积光致抗蚀剂层并且图案化该光致抗蚀剂层以提供贯穿其中的开口而构成。开口在最靠近绝缘层的层的部分较宽。该层用作沉积导电材料层的荫罩。在本发明的一个实施例中，第二聚合物层位于绝缘层和第二导电层之间。绝缘层优选由烘烤以交联光致抗蚀剂的光致抗蚀剂层构成。聚合物层包括电致发光材料，其优选基于聚芴。
