the video bus into pictorial images the picture elements 40 imprint information of shades of gray polarization and color on light passing therethrough the first display module 14 receives control signals from the processor module 26 see fig1 the first display module 14 also receives synchronization signals from the synchronization module 24 via the video memory module 28 which instructs the first display module 14 on which image to use when to present an image and when to erase an image it should be mentioned that use of a flat panel matrix display is critical to maintaining a pixel of input information on only one fixed position picture element 40 of the first display module 14 the foregoing display does not drift as a pixel on a cathode ray tube might still referring to fig3 the second display module 18 is configured substantially the same as the first display module 14 aforementioned except that the first display module 14 abuts the first optics module 16 and the second optics module 20 the second display module 18 is the critical module which allows information imprinted on the light from the first display module 14 to interact with the information presented on the second display module 18 as the imprinted light passes through.
