Abstract

PURPOSE:To improve the brightness and the quality by employing such fluorescent face where one light emission area of a fluorescent material element is made larger than those of other fluorescent material elements. CONSTITUTION:In one random pair three light emission elements of white W6, green G7 and red R8 in a fluorescent face and electron beams W9, G10 and R11 for exciting each of them, when a beam 10 for exciting the element 7 will excite the element 6 it cann't be perceived by human if the area is small thereby causes no influence on the indication capacity of the color Braun tube. It is true for other elements. Experimentally said light emission area 12 may be upto 5.0% of the light emission area of G or R, for example. Consequently the light emission area of W6 is made larger than those of G7, R8. Consequently the brightness is improved and the quality is also improved.
