The invention concerns a stereoscopic display device comprising a transmissive image reproducing element (10), two light sources (22, 24), optical means to direct the light emitted by one light source towards the right eye and to direct the light emitted by the other light source towards the left eye, and control means for displaying alternately an image for the right eye and an image for the left eye on the image reproducing element (10), and for activating the source emitting light for the right eye only when the image for the right eye is displayed and for activating the source emitting light for the left eye only when the displayed image is for the left eye. According to the invention, the optical means (28) are of the converging type in order that the light provided by each light source (22, 24) converges towards the corresponding eye (30, 32). As the energy provided by the light sources is efficiently used the device needs minimum power. <IMAGE> |
