Abstract
A flat tube display is fabricated having internal structural supports running the height of the display at selected periodic intervals. This construction permits light weight face plates and back plates to be used in the construction of displays independent of display size, yet still providing the required stength to withstand atmospheric pressure. By compressing the dot matrix of the first plate of the switching stack, relatively large areas free of the dot matrix are provided whereby the internal supports may be attached without interferring with the operation of the display. The control plates of the flat tube display are pseudo-aligned to the phosphor screen. Electrons are injected into the stack channel comprising plates at successively higher positive potentials so that self-guiding through the channels at 100% transmission is achieved. Apertures of the control stack are fabricated into horizontal slots to provide for increased brightness as a result of greater electron transmission through the stack.
