    摘要: A method of manufacturing an organic-light emitting diode (OLED) display can include providing on a substrate a first electrode associated with a first sub-pixel and a second electrode associated with a second sub-pixel, wherein a gap is formed between the first electrode and the second electrode and wherein the first electrode and the second electrode are positioned in a well having boundaries defined by a confinement structure on the substrate. The method can also include depositing in the well with the electrodes positioned therein, active OLED material to form a substantially continuous layer of active OLED material that spans the boundaries of the well such that a surface of the layer of active OLED material that faces away from the substrate has a non-planar topography. The depositing can be via inkjet printing.

    摘要: A drying chamber for drying a substrate patterned with display areas wetted by OLED materials dissolved or suspended in a volatile carrier liquid and separated from one another by dry boundary regions. A mask adjusts drying rate of the carrier liquid during vacuum extraction using vapor-transmissive areas opposite the wet areas and vapor-barrier regions opposite the dry boundary regions, or by confining the wet areas collectively in a chamber volume small enough to quickly saturate with the carrier liquid before vacuum extraction.

    摘要: Apparatus and techniques are described herein for use in manufacturing electronic devices. such as can include organic light emitting diode (OLED) devices. Such apparatus and techniques can include using one or more modules having a controlled environment. For example, a substrate can be received from a printing system located in a first processing environment, and the substrate can be provided a second processing environment, such as to an enclosed thermal treatment module comprising a controlled second processing environment. The second processing environment can include a purified gas environment having a different composition than the first processing environment.

    摘要: An ink printing process employs per-nozzle droplet volume measurement and processing software that plans droplet combinations to reach specific aggregate ink fills per target region, guaranteeing compliance with minimum and maximum ink fills set by specification. In various embodiments, different droplet combinations are produced through different print head/substrate scan offsets, offsets between print heads, the use of different nozzle drive waveforms, and/or other techniques. Optionally, patterns of fill variation can be introduced so as to mitigate observable line effects in a finished display device. The disclosed techniques have many other possible applications.
