In a portable electronic device (100) having a plurality of near field communication applications stored within a plurality of execution environments, an application discovery manager (311) is configured to automatically select and launch one or more of the near field communication applications. A near field communication circuit (300) receives a near field communication request from an external near field communication device (700). The application discovery manager (311) identifies a near field communication technology, a protocol, and an application identifier and then references a registry table (313) to determine identification parameters corresponding with the identified information. The application discovery manager (311) then selects a near field communication application and launches it. The application discovery manager (311) further configures a routing switch (316) to direct data between the near field communication circuit controller (301) and the appropriate execution environment.

An electrophoresis device includes a pair of substrates, a plurality of pixel electrodes, and a common electrode formed on the pair of substrates, a liquid material formed by dispersing charged particles sealed between the pair of substrates and a driving circuit for applying a voltage to the pixel electrodes and the common electrode to generate an electric field therebetween. When display image is changed, the driving circuit generates a first electric field between all the pixel electrodes and the common electrode to delete the image displayed by that time over the entire display region. Then, when new display image is written, the driving circuit generates a second electric field between the pixel electrodes corresponding to display and the common electrode, and generates a third electric field between the common electrode and the pixel electrodes not corresponding to display.

Embodiments disclosed herein may generate and transmit power waves that, as result of their physical waveform characteristics (e.g., frequency, amplitude, phase, gain, direction), converge at a predetermined location in a transmission field to generate a pocket of energy. Receivers associated with an electronic device being powered by the wireless charging system, may extract energy from these pockets of energy and then convert that energy into usable electric power for the electronic device associated with a receiver. The pockets of energy may manifest as a three-dimensional field (e.g., transmission field) where energy may be harvested by a receiver positioned within or nearby the pocket of energy.

Providing a light emitting device capable of suppressing the variations of luminance of OLEDs associated with the deterioration of an organic light emitting material, and achieving a consistent luminance. An input image signal is constantly or periodically sampled to sense a light emission period or displayed gradation level of each of light emitting elements of pixels and then, a pixel suffering the greatest deterioration and decreased luminance is predicted from the accumulations of the sensed values. A current supply to the target pixel is corrected for achieving a desired luminance. The other pixels than the target pixel are supplied with an excessive current and hence, the individual gradation levels of the pixels are lowered by correcting the image signal for driving the pixel with the deteriorated light emitting element on as-needed basis, the correction of the image signal made by comparing the accumulation of the sensed values of each of the other pixels with a previously stored data on a time-varying luminance characteristic of the light emitting element.
