Abstract:
1. A secure display system, comprising: a display screen comprising at least two independent matrices formed of pixels, each of the matrices being controlled by an independent graphic channel, said matrices having independent inputs, a light box comprising at least two independent subassemblies, each subassembly backlighting a half-screen of the display screen, two bypass switches, each bypass switch connected on a one-to-one basis with one of the two graphic channels and controlled by the connected graphic channel, each bypass switch selectively connecting the input of each of the matrices to a signal output the graphic channel that controls the bypass switch or to the output of a central assembly, wherein the central assembly mixes images originating from the two independent graphic channels into a full screen image, separates the full screen image into half-screen portions, and outputs one of the separated half-screen portions to each of the bypass switches, wherein each graphic channel generates an image and outputs the image to a bypass switch and the central assembly, and a first power supply unit and a second power supply unit.
