Poly-siloxane material may be used to form an insulating structure in an
organic light-emitting device (OLED). In addition to the insulating
structure, an OLED may have an electro-luminescent organic layer
separated into light-emitting elements, e.g., display pixels, arranged
between electrode layers. A voltage applied across the electrode layers
causes the device to emit light. One type of insulating structure may be
a bank structure formed from a thin sheet of poly-siloxane with apertures
corresponding to the display pixels. Pixels may be formed with the
deposit of one or more layers of organic material into the apertures.
Another type of-insulating structure may be one or more insulating
strips, which may separate an electrode layer into electrode strips
during construction and/or insulate electrode strips while the OLED is in
operation.
