摘要： A shadow mask for color picture tubes has a cathode-side surface covered with a heat-insulating layer, an electron reflecting and absorbing layer, and a heat-emitting cover layer. Some of the electrons are reflected while others are absorbed in the cover layer and transformed to heat, but the heat does not act directly on the mask and is emitted into the interior of the tube. Local temperature differences which particularly occur with high contrast pictures and cause partial doming of the perforated mask are reduced.

摘要： A shadow mask for a color picture tube a thermal includes insulating layer preventing heat transfer to an apertured shadow mask. The side of the mask directed toward the cathode of the color picture tube is coated with a heat-insulating layer including particles having a porous structure. The pores may contain heavy metals or heavy metal compounds so that electron reflection and absorption occurs directly within the layer. The resulting heat is transferred to the interior of the picture tube instead of to the mask.
