An apparatus is provided which comprises a first layer that is switchable between a first state wherein light transits the layer substantially unimpeded and a second state wherein light is substantially blocked from transiting the layer. The apparatus further comprises a second layer which is substantially transparent and comprises light emitting elements, such as organic light emitting diodes (OLED.) A face of the first layer contacts a face of the second layer such that the first layer controls the transit of light through the second layer. The first layer may be a layer of smart or switchable glass and may comprise a layer of electrochromic material. Uses of the apparatus in car compartment dividers, windows and sunroofs is described along with methods of manufacture of the apparatus.
