Abstract
The invention relates to a display tube comprising an envelope portion 2 having an inner surface provided with a first electrically conductive layer 7 and a faceplate 1 having an inner surface provided with a second electrically conductive layer 8, which faceplate 1 is secured to the envelope portion 2 at a sealing edge 15, and further comprising a contacting layer 33 which is deposited in an area partially overlapping the first electrically conductive layer 7 and the second electrically conductive layer 8 in order to electrically connect said first electrically conductive layer 7 to said second electrically conductive layer 8.
Claims11
A display tube comprising an envelope portion (2) having an inner surface provided with a first electrically conductive layer (7) and a faceplate (1) having an inner surface provided with a second electrically conductive layer (8), which faceplate (1) is secured to the envelope portion (2), and further comprising connection means to electrically connect said first electrically conductive layer (7) to said second electrically conductive layer (8), characterized in that said connection means comprise a contacting layer (33) which is provided in an area partially overlapping the first electrically conductive layer (7) and the second electrically conductive layer (8).
A method of electrically connecting a first electrically conductive layer (7) provided on the inner side of an envelope portion (2) of a display tube and a second electrically conductive layer (8) provided on the inner side of a faceplate (1) of the display tube, which faceplate (1) is secured to the envelope portion (2) at a sealing edge (15), by depositing a contacting layer (33) of a conductive material on the inner side of the display tube, which conductive material is deposited in an area bridging the sealing edge (15) and electrically contacting the first electrically conductive layer (7) and the second electrically conductive layer (8).
