  • Patent number: 12140571
    Abstract: A multiple degree of freedom sample stage or testing assembly including a multiple degree of freedom sample stage. The multiple degree of freedom sample stage includes a plurality of stages including linear, and one or more of rotation or tilt stages configured to position a sample in a plurality of orientations for access or observation by multiple instruments in a clustered volume that confines movement of the multiple degree of freedom sample stage. The multiple degree of freedom sample stage includes one or more clamping assemblies to statically hold the sample in place throughout observation and with the application of force to the sample, for instance by a mechanical testing instrument. Further, the multiple degree of freedom sample stage includes one or more cross roller bearing assemblies that substantially eliminate mechanical tolerance between elements of one or more stages in directions orthogonal to a moving axis of the respective stages.

  • Patent number: 9153794
    Abstract: A low temperature, low cost method of encapsulating organic light emitting diodes (OLED) that avoids damage to the OLED device. A metal passivation layer is formed using a plasma, UV-ozone, or wet chemical treatment, wherein the metal passivation layer serves to encapsulate and protect the OLED from moisture and oxygen. Alternatively, a buffer layer and a metal layer are formed onto the OLED and the metal layer is treated using a plasma, UV-ozone, or wet chemical treatment, to form a metal passivation layer that serves to encapsulate and protect the OLED from moisture and oxygen.

  • Publication number: 20150125975
    Abstract: A low temperature, low cost method of encapsulating organic light emitting diodes (OLED) that avoids damage to the OLED device. One method comprises forming a metal passivation layer using a plasma, UV-ozone, or wet chemical treatment, wherein the metal passivation layer serves to encapsulate and protect the OLED from moisture and oxygen. Another method comprises forming a buffer layer and a metal layer onto the OLED and then treating the metal layer using a plasma, UV-ozone, or wet chemical treatment, to form a metal passivation layer that serves to encapsulate and protect the OLED from moisture and oxygen.
