In front of the driver there is arranged a screen (20) with a variable transmission coefficient. The headlamps (10, 11) of the vehicle send out periodic pulses of short duration with respect to the period. The transmission coefficient of the screen (20, 23, 24) varies in such a way that it is transparent during the duration of the light pulses and that the screen is substantially less transparent between these pulses.

In a method of construction of an electrooptical display screen and especially a liquid-crystal screen, a control point of an image element is provided with a coupling element of ferroelectric material between an electrode and a control lead.

Electrooptical display screen and a method of fabrication of said screen

The present invention relates to methods for protecting against drop-outs in a sound signal recorded on a video-disc. It consists in recording onto a video-disc the same sound signal through the sub-carriers with a constant delay from one to the other. On reading out this video-disc, the two sub-carriers are restored to synchronism and the sub-carrier not altered is chosen for playing the sound signal.
