    • An electroluminescent device (1) comprising a lower electrode layer (10), and an upper electrode layer (2), which are both connectable to a driving circuit (3) and electrically accessible from below, is disclosed. One or more functional layers (5) are disposed between the electrode layers (2, 10) to form an electroluminescent area The device (1) comprises a relief pattern comprising insulating positively sloped ribs (7), in-between which a well (13) is formed. The upper electrode layer (2) has an extension over at least one positively sloped rib (7), and the well (13) is arranged on a first side (7), and a contact surface (4) is arranged on a second side (7″) of the positively sloped rib (7). The extension of the upper electrode layer (2) provides for at least part of said contact surface (4) being covered by said upper electrode layer (2). Thereby, the upper electrode layer (2) becomes accessible from below in the contact surface (4). The device (1) may be used for structured cathodes in active matrix displays, and/or for reducing the sheet resistance in transparent/semi-transparent cathodes.
    • 公开了一种电致发光器件(1),其包括下电极层(10)和上电极层(2),它们都可连接到驱动电路(3)并且可从下方电接触。 一个或多个功能层(5)设置在电极层(2,10)之间以形成电致发光区域。装置(1)包括浮雕图案,该浮雕图案包括绝缘的正倾斜肋(7) ) 形成了。 上电极层(2)在至少一个正倾斜肋(7)上具有延伸部,并且阱(13)布置在第一侧(7)上,并且接触表面(4)布置在第二侧 (7)的凸缘(7“)。 上电极层(2)的延伸部分使所述接触表面(4)的至少部分被所述上电极层(2)覆盖。 由此,在接触面(4)中,上部电极层(2)能够从下方进入。 器件(1)可用于有源矩阵显示器中的结构化阴极和/或用于降低透明/半透明阴极中的薄层电阻。
