    摘要： Electronic device and associated methods with multiple well areas located on a common substrate, where each well area is defined by at least three bank structures that form the side walls of the well area. Within each well area, there are at least two electrode segments where the electrode segments are separated laterally by at least one insulating bank where the insulating bank(s) are thicker than the electrode segments. There is at least one charge transporting layer completely filling the well area in direct contact and overlying both the electrode segments and the insulating bank(s). The well areas are filled using solution methods such as inkjet. Such devices have improved uniformity across the active areas.

    摘要： The present invention relates to a display device, in particular a backlit display device having a visible side and a back side, which appears opaque in colour and texture on viewing of the visible side without backlighting, but, with the backlighting switched on, is sufficiently transparent that the transmission of information by the light source from the back side is possible, and to the production of a display device of this type and to the use thereof.

    摘要： The present invention relates to a method for forming an organic element of an electronic device having at least two different pixel types including a first pixel type (pixel A) and a second pixel type (pixel B), —wherein at least one layer of pixel A is deposited by applying an ink A containing at least one organic functional material A and at least one solvent A by a printing process, —wherein at least one layer of pixel B is deposited by applying an ink B containing at least one organic functional material B and at least one solvent B by a printing process, —wherein at least one organic functional material A and at least one organic functional material B are different, and —wherein at least one solvent A and at least one solvent B are different, characterized in that both inks, ink A and ink B, in addition contain at least one common solvent S, and characterized in that the boiling point of solvent A and the boiling point of solvent B is at least 10° C. lower than the boiling point of the common solvent S.
