A light-emitting device contains getter material () typically distributed in a relatively uniform manner across the device's active light-emitting portion. An electron-emitting device similarly contains getter material (, and) typically distributed relatively uniformly across the active electron-emitting portion of the device.

Light-emitting and electron-emitting devices having getter regions

A display () with enhanced image contrast contains an image-producing component () and a set of shutter strips (). The image-producing component, typically a flat-panel device, has multiple imaging lines that provide light to produce an image. Each shutter strip is situated in front of one or more associated imaging lines. By appropriately switching the shutter strips between light-absorptive and light-transmissive states, the image contrast is enhanced. The shutter strips are typically implemented with a liquid-crystal display structure. The switching of the shutter strips is typically performed with a control component () which utilizes light to control the shutter switching and which is synchronized to signals (or/and) that control the imaging lines.

Display with active contrast enhancement

An apparatus for removing contaminants from a display device is disclosed. In one embodiment, an auxiliary chamber is adapted to be coupled to a surface of a display device such that contaminants within the display device can travel from the display device into the auxiliary chamber. A getter is disposed in the auxiliary chamber. The getter is adapted to capture the contaminants once the contaminants travel from the display device into the auxiliary chamber. In other embodiments, the getter is disposed in the border region surrounding the active area of the display.

Apparatus for removing contaminants from a display device

A low-contaminant dual layer apparatus adapted for use in a flat panel display device is described. The apparatus includes a dual layer electroplated structure for containing the movement of electrons. The electroplated structure resides within an active region of the flat panel display device. The electroplated structure has a cavity adapted to having sub-pixel forming material deposited within and contains substantially no organic material.

Auxiliary chamber and display device with improved contaminant removal

A field emission display having an improved operational life. In one embodiment of the present invention, the field emission display comprises a plurality of row lines, a plurality of column lines, and a plurality of electron emissive elements disposed at intersections of the plurality of row lines and column lines, a column driver circuit, and a row driver circuit. The column driver circuit is coupled to drive column voltage signals over the plurality of column lines; and, the row driver circuit is coupled to activate and deactivate the plurality of row lines with row voltage signals. Significantly, according to the present invention, operational life of the field emission display is substantially extended when the electron emissive elements are intermittently reverse-biased by the column voltage signals and the row voltage signals. In another embodiment, the row driver circuit is responsive to a SLEEP signal. The row driver circuit, upon receiving the SLEEP signal, drives a sleep-mode voltage over the row lines to reverse-bias the electron emissive elements.

System and method for improving emitter life in flat panel field emission displays

A flat panel display and a method for forming a flat panel display. In one embodiment, the flat panel display includes a wall which is held in place by a structure formed either on the faceplate or on the backplate. In one embodiment the supporting structure is formed by two adjacent walls that form a slot which mechanically restrains the wall. In another embodiment a slot is formed within the faceplate and the walls of the slot mechanically restrain the wall. In one embodiment wall segments are inserted into supporting structures that mechanically restrain each wall segment. In another embodiment a UV curable or a heat curable adhesive is used to maintain walls in their proper alignment and position. In yet another embodiment a conductive material is melted so as to bond conductive lines located on the wall and conductive lines located on the faceplate. This bond electrically connects the conductive lines located on the wall and the conductive lines located on the faceplate and maintains the wall in the proper alignment. The present invention eliminates the need for feet which attach to individual walls for maintaining the walls in the proper alignment.

A getter (,) is situated in an auxiliary compartment (,) of a hollow structure (,and,) having a larger main compartment (,). The auxiliary compartment is situated outside the main compartment and is connected to the main compartment so that the two compartments reach largely the same steady-state compartment pressure. The getter is activated by directing light energy locally through part of the hollow structure and onto the getter. The light energy is typically furnished by a laser beam (,). The getter, typically of the non-evaporable type, is usually inserted as a single piece of gettering material into the auxiliary compartment. The getter normally can be activated/re-activated multiple times in this manner, typically during sealing of different parts of the structure together.
