Microdot fluorescent matrix screen addressing process

Abstract From the Canadian patent

Process for regulating the brightness of a microtip fluorescent screen and apparatus for performing this process. The screen is of the matrix type and is addressed by a scan of the rows a pixel being, formed at each row-column intersection. For an illuminated pixel, for a selection time T of the corresponding row, a quantity of charges is emitted by the associated microtips. The brightness is regulated during the selection time of each row by controlling the quantity of charges emitted by the microtips of each pixel to be illuminated, said charge quantity being identical for each pixel.
