Visual display

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 phosp...

Summary: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.
