Abstract
A light-emitting device contains getter material (58) typically distributed in a relatively uniform manner across the device's active light-emitting portion. An electron-emitting device similarly contains getter material (112, 110/112, 128, 132, and 142) typically distributed relatively uniformly across the active electron-emitting portion of the device.
