Reduction of smearing in cold cathode displays |
摘要 |
A problem associated with field emission displays is that of 'smearing' where an otherwise sharp image appears to be surrounded by a diffuse halo of light. Our investigations have suggested that this is due to spurious reflections from the surface of the gate electrode layer. To eliminate these we have deposited an anti-reflection coating on the top surface of the gate electrode layer. This prevents the reflection of light rays travelling away from the phosphor layer towards the cathode. Such rays, if their reflection were allowed, would emerge at a different spot in the display from what was intended, resulting in a false image. A method for manufacturing a field emission display based on this approach is also described.
