Abstract
The disclosed device comprises an image circuit formed by an image generator, a micro-zone processing unit, a screen interface and an LCD screen. To optimize the performance characteristics of the screen as a function of the angle of observation, the position of the observer is detected (by a detector) and, as a function of this position, the appropriate profile of luminosity of the micro-zones of the screen is selected.
