ABSTRACT:
A device and method is disclosed for achieving true color picture display during the warm-up phase as well as during the operating phase of a color television picture tube. The device is a screen-coating lens which has been corrected so as to assure that the light source, when exposing the phosphor materials, will correspond to the point of maximum arching of the shadow mask. The method involves exposing the phosphor dots through a corrected lens which takes into account the maximum arching of the shadow mask during the warm-up phase of a color television.
