— A new type of a flat and thin display with a secondary‐emission electron source will be reported. In this display device, electrons are multiplied between two secondary emission plates under a high‐frequency electric field. This has a number of advantages over a field‐emission display: the emission comes from flat plates, which reduces the lifetime problems of ion bombardment of field‐emitter tips. Furthermore, the electron emission is space‐charge limited, which gives a uniform electron distribution. The electrons are extracted from the source and accelerated to a phosphor screen to generate light. Gray levels are made by pulse width modulation.
