    Abstract: An organic light emitting diode (OLED) incorporating an enhanced light extraction apparatus in the transparent conductive oxide layer is disclosed. The apparatus for light extraction may comprise a transparent substrate, a transparent electrode comprising one or more discontinuities, and an organic light emitting material stack. The transparent electrode may be disposed on the transparent substrate and comprise a series of features or discontinuities that enhance light extraction improve energy efficiency in the OLED device. The discontinuities may be discrete or continuous and may interrupt the conductivity of the transparent conductive oxide layer.

    Abstract: A method for in-situ measurement of a thickness of a coating deposited by a deposition process, includes the steps of initiating deposition within a deposition chamber such that a first coating forms on an outer surface of a probe disposed in the deposition chamber, wherein the probe comprises a coil assembly including at least one coil, wherein the probe is separated by a distance from a substrate disposed within the deposition chamber; exciting the coil assembly with a first alternating current to produce a first time-varying magnetic field, the first time-varying magnetic field generating an eddy current in the first coating; determining a metric related to an inductance or resistance of the coil assembly, wherein a value of the metric is related to a first thickness of the first coating and results at least partially from an eddy current magnetic field produced by an eddy current in the coating; and correlating the first thickness of the first coating to a second thickness of a second coating deposited on a surface of the substrate.

    Abstract: A liquid lens comprising: a lens body including a cavity, a control electrode, and a common electrode; a first liquid disposed within the cavity and in electrical communication with the common electrode; a second liquid disposed within the cavity; an insulating layer in contact with the first liquid and the second liquid and separating the first liquid and the second liquid from the control electrode; and a driver driving a voltage differential across the common electrode and the control electrode, with the first liquid resisting current flow between the common electrode and the control electrode and thereby raising a temperature of the first liquid from a current temperature to a predetermined temperature, which is higher than the current temperature. The driver raises the temperature of the first liquid from the current temperature to the predetermined temperature by increasing a frequency of a voltage waveform of the voltage differential.
