Paper Abstract

The main parameters determined by colour picture tube manufactu— rers are brightness and the ratio of anode currents of electron beams at white luminescence of the screen I I . To determine there parameters it is necessary to set the white colour of the luminescence and to measure the brightness of the white field luminescence, as well as the total anode current of electron gun and anode current for every beam. it is especially important to determine with the utmost accuracy the white colour of the screen luminescence, as it is known that set— ting of two different white colours with colour temperatures of 6500 K =O.3i3. v=O.329' and 9300 H (x=O28i. v=0.31fl on the same colour picture tube, operating under a certain mode at the same total anode current of electron gun, gives rise to changes in the screen lumines cence brightness up to several per cents, x and y being the chrornacity coordinates of the system XYZ as per 1931 CIE Standards.
