A television flat panel display which has a housing, a viewing screen disposed in the housing; the viewing screen comprises a first sheet disposed in the housing as the front sheet of the display, a power input arrangement configured and disposed to power the display, an arrangement to produce picture elements as pixels, this arrangement at least comprising: an array of electrodes, a material configured to be energized by the electrodes, and addressing circuitry connected to the electrodes and the power input arrangement, the addressing circuitry being configured to convert electrical signal input to the material configured to be energized into optical signal output viewable as pixels on a particular point on the first sheet of the display. The material to be energized and the electrodes are disposed in a channel member comprising a plate-like structure with a plurality of ribs forming a plurality of grooves. The ribs are spaced apart at a predetermined pitch to correspond to pixel resolution of the flat panel display. A layer on the ribs comprises a substantially non-transparent material with a sufficient optical density to minimize stray radiation and/or leakage radiation in the ribs to thereby enhance picture and/or color contrast of the flat panel display. The assembly also includes apparatus to maintain the channel member and said first sheet in alignment with respect to one another.
