Definitions

the invention relates to a method for producing a contact edge on a fluorescent screen for flat image display devices.
image display devices are generally known (see. DE-PS 24 12 869).
the invention is based on the object of avoiding the disadvantages indicated and, in particular, of specifying a method for producing a contact edge which ensures vacuum-tight contacting of the screen and can also be carried out cost-effectively by means of process-economic measures.
This object is achieved by a method for producing a contact edge on a fluorescent screen for flat image display devices with the features of claim 1.
the burned-in layer has a resistance value of ⁇ 1 ⁇ from contact to contact.
the figure shows a top view of the fluorescent screen purely schematically.
a float glass pane 306 x 216 x 12mm is used as screen glass 2 for the fluorescent screen.
This disc is lapped on one surface and polished-etched (anti-reflective coating) and then cleaned using customary methods.
the screen glass 2 turns on at approx. 510 o C Air annealed and finely cooled for approx. 15min (approx.1.5 ° C / min), the fine cooling serves to avoid compaction in later temperature processes with 440 ° C to 450 ° C.
the luminescent layer 3 is deposited with an aluminum layer 4 as a protective layer with a thickness of approximately 10 nm to 500 nm, preferably approximately 40 nm, so that good contact with the edge layer 1 (contact edge) is achieved by overlapping.
