ABSTRACT:
A visual has a multilayer ceramic substrate (1) with an emission layer (2) on its front face. The substrate is mounted on carrier (4) with a L-shaped cross-section, via the foot (41) of the L. A glass face plate (5) is on the top of the main limb (42) of the L. The face plate has a phosphor layer (6) on its inside surface. A succession (7) of vias and interconnects in the L provides connection from the substrate (1) to the phosphor layer. A band (8) of frit is screen printed onto the inside of the face plate, peripherally of phosphor layer. In a corresponding position on the top of the main limb, a groove (9) is formed. On assembly of the face plate to the carrier, the frit (8) fits into the groove (9). The face plate abuts the top of the limb (42), thereby defining the separation of the face plate and the emission substrate.
