DISPLAY TUBE

摘要

Display tube. A display tube, for example a projection television display tube, having a very efficient cooling of the display screen and in which the Schlieren effect does not occur is obtained by causing a laminar flow of a layer of liquid having a thickness smaller than 1 mm in the space on the outside in front of the display window of the tube. Said laminar flow is obtained by the combination of the thin layer of liquid with a suitable viscosity of the liquid and the smooth connection of a chamber to at least the inlet aperture of the space.
