FIELD: physics.
SUBSTANCE: display device has a layer of light radiation and display and a supporting layer. Layer of light radiation and display is arranged above the supporting layer and is used to display an image due to light radiation. Supporting layer contains a matrix formed by a photovoltaic material, which is arranged horizontally and directly under the circuits of excitation in the layer of light radiation and display. Matrix formed by the photovoltaic material forms a channel for absorption of light emitted from the layer of light radiation and display and conversion thereof into current. Layer of light radiation and display has a cathode, a reflector, a conducting layer and an anode in the order from the top to the bottom.
EFFECT: longer operation.
