Abstract: Embodiments of the disclosed subject matter provide a device that includes an organic light emitting device (OLED), and a drive circuit to control the operation of the OLED, comprising a response time accelerator thin film transistor (TFT) configured to short or reverse bias the OLED for a predetermined period of time during a frame time. Other embodiments include an OLED having a plurality of sub-pixels, where one or more of sub-pixels configured to emit light of at least a first color comprises a first emissive area and a second emissive area that are independently controllable, where the first emissive area is larger than the second emissive area. The controller is configured to control the second emissive area to have (i) a higher brightness, and/or (ii) a higher current density than the first emissive area for a first sub-pixel luminance level that is less than a maximum luminance.

Abstract: Sensors and lighting components are provided that are capable of matching an emitted color to a color observed at a remote location. The sensor measures a light characteristic at a first location, and provides data to a remote lighting component, such as via a wireless connection. The lighting component is configured to emit light based upon the light characteristic, and thus is able to match an observed lighting condition. The lighting component may match the color, intensity, temperature, pattern, texture, or other characteristic of light at a remote location.
