Abstract
A display system with a matrix type flat panel, for example a liquid crystal panel, has addressing circuits to obtain a television type interlaced image. These circuits are divided into several blocks, both for the addressing of even-numbered and odd-numbered columns and for the addressing of even-numbered and odd-numbered lines, in order to obtain a high-definition image. The graphic processor means used to prepare the video signals to be displayed comprise two sub-groups, one for each of the odd or even image. The two subgroups are respectively associated with two different data measuring devices giving the same essential information, to allow at least one display to be maintained even if one device malfunctions, each of them having at least one symbol generator associated with an image memory to produce a protected display of essential data for use.
