Abstract

PURPOSE: To prevent browning of a face glass caused by the radiation of over scanning electron beam by applying negative electric potential to a transparent conductive membrane provided on the internal surface of the face.
CONSTITUTION: A negative electric potential relative to a cathod is applied to a transparent conductive membrane 12 formed on the internal surface of the face 4c of a projection Braun tube. If an electron beam (a') may miss a target 9 and tends to hit on the face 4c due to over-scanning, the electron beam is repelled and absorbed by a metallic tube 6, a metallic target 9 or a mounting member 1 as the potential of the face 4c is negative, thus browning of the glass of the face 4c is prevented so that reduction in briliance, clouding of colors and X-ray generating are prevented.
