FIELD: physics.
SUBSTANCE: device comprises a control unit, a temperature control system, a heating system having a frame which encases a liquid crystal cell in thermal contact therewith. Along at least one side of the liquid crystal cell there are heating elements which are separately powered from the control unit and made in the form of light-emitting diodes, the radiation of which falls on the front surface of the liquid crystal cell at an angle. The light-emitting diodes are in thermal contact with the encasing frame.
EFFECT: providing fast heating of a liquid crystal cell to operating state at low ambient temperatures.
