    Abstract: PROBLEM TO BE SOLVED: To provide a display screen, which can withstand high voltage between electrodes, by providing a cathode engaged with an electron extracting grid, an anode having two type fluorescent elements, which are polarized at the same electrical potential, and at least two additional overlapped grids, and providing each grid with a hole having a diameter smaller than that of a coaxial hole of other additional grid. SOLUTION: An intersection of a line of extracting grids 3, which has holes 4 corresponding to a cathode 1 and a microchip 2, and a line of the cathode 1 regulate a picture element. Each picture element is divided into three auxiliary picture elements Pr, Pg, Pb, which are regulated by three coaxial holes provided by additional grids 15, 16, 17, and the divided auxiliary picture elements face to corresponding fluorescent elements 7r, 7g, 7b on a common electrode 9. The additional grids 15, 16, 17 include coaxial holes 19, 20, 21 for activating or restricting the corresponding auxiliary picture elements. These coaxial holes 19, 20, 21 has a diameter smaller than that of the coaxial holes 22, 24 and 20, 24 and 20, 22 of other grids.

    Abstract: The screen has a cathode (2) formed of microdots arranged in columns (K1-K3) under an insulating coating which carries the pixel selection grid divided into rows (L1-L3). The colour selection grid has groups of slits (e.g. A1R,A1G,A1B) extending in the direction of the columns, each group covering the width of one column. Slits of the same rank in each group are connected to a common terminal. The anode is similarly divided into groups of parallel strips of luminophors of the primary colours, each strip corresponding to one slit, and all strips being returned to the same voltage.
