Abstract
The invention relates to data display devices having a segmented structure. It provides a display device whose adjacent coplanar segments are divided up into complementary areas respectively connected to excitation units controlled simultaneously in such manner as to produce, in the absence of break down, a homogeneous display of the segments. The invention applies to display by elementary sources of light or by liquid crystals and other materials having electro-optical properties.
