摘要:
An apparatus for removing contaminants from a display device (400) is disclosed. In one embodiment, an auxiliary chamber (408) is adapted to be coupled to a surface of a display device (400) such that contaminants within the display device can travel from the display device into the auxiliary chamber. A getter (410) is disposed in the auxiliary chamber (408). The getter is adapted to capture the contaminants once the contaminants travel from the display device (400) into the auxiliary chamber (408). In other embodiments, the getter is disposed in the border region surrounding the active area of the display.
摘要:
A getter (50 or 74) situated in a cavity of a hollow structure, such as a flat-panel device, is activated by directing light energy locally through part of the hollow structure and onto the getter. The light energy is typically provided by a laser beam (60). The getter, typically of the non-evaporable type, is usually inserted as a single piece of gettering material into the cavity. The getter normally can be activated/re-activated multiple times in this manner, typically during the sealing of different parts of the structure together. The getter-containing cavity can be formed by a pair of plate structures (40 and 42) sandwiched around and outer wall (44), or by an auxiliary compartment (72) connected to a larger main compartment (70) typically constituted by the plate structures and outer wall.
摘要:
A light-emitting device is provided with getter material (58) that can readily be distributed in a relatively uniform manner across the device's active light-emitting portion. An electron-emitting device is similarly provided with getter material (112, 110/112, 128, 132, and 142) that can readily be distributed relatively uniformly across the active electron-emitting portion of the device. Techniques such as thermal spraying, angled physical deposition, and maskless electrophoretic/dielectrophoretic deposition can be utilized in depositing the getter material.
