Abstract: Devices and techniques are provided in which an OLED panel is operated in two modes. The first mode operates in a standard way to display an image or video or otherwise illuminate sub-pixels of the panel. In the second mode, some pixels are operated at a lower brightness than in the first mode. The use of multiple modes allows for improved sub-pixel lifetime and reduced sub-pixel and image degradation.

Abstract: Implementations of the disclosed subject matter provide a window, an energy and light producing device including at least one transparent photovoltaic device and at least one non-transparent Organic Light Emitting Device (OLED) in an optical path of the window. A controller may control the operation of the non-transparent OLED of the energy and light producing device. An energy storage device may be electrically coupled to the controller and the energy and light producing device to store energy generated by the transparent photovoltaic device and to power the non-transparent OLED. In some implementations, a LED or OLED may be mounted in the frame of the window and may be powered by the energy storage device.
