Abstract (en)
Colour display tube of the 3-in-line type having a display screen with a pattern of phosphor lines. The display tube has an internal shield with two long walls and two short walls. Each long wall is provided with at least one slit extending in the longitudinal direction of the tube and being remote from the edges of the walls, while for locally increasing the magnetic resistance the shield is particularly provided with a short transverse slit between at least one slit end and the opposite edge. <IMAGE>
