Field emission displays with focusing/deflection gates

摘要

A field-emission display (FED) device has a cathodoluminiescent screen and an emitting assembly for selectively energizing pixels on the screen to form an image. The emitting assembly includes an array of emitters arranged in addressable rows, and controllable focusing/deflection arrangement associated with the respective emitters to permit emissions from the emitters in a group of addressed rows to be simultaneously directed onto a common energized pixel on the screen.
