摘要： Methods for compensating for brightness variations in a field emission device. In one embodiment, a method and system are described for measuring the relative brightness of rows of a field emission display (FED) device, storing information representing the measured brightness into a correction table and using the correction table to provide uniform row brightness in the display by adjusting row voltages and/or row on-time periods. A special measurement process is described for providing accurate current measurements on the rows. This embodiment compensates for brightness variations of the rows, e.g., for rows near the spacer walls. In another embodiment, a periodic signal, e.g., a high frequency noise signal, is added to the row on-time pulse in order to camouflage brightness variations in the rows near the spacer walls. In another embodiment, the area under the row on-time pulse is adjusted to provide row-by-row brightness compensation based on correction values stored in a memory resident correction table. In another embodiment, the brightness of each row is measured and compiled into a data profile for the FED. The data profile is used to control cathode burn-in processes so that brightness variations are corrected by physically altering the characteristics of the emitters of the rows.

摘要： A spatial light modulator is disclosed, along with methods for making such a modulator that comprises an array of mirror devices each having at least a first electrode and a second electrode. The first electrode is designated for driving the mirror plate of the micromirror device to an ON state, and the second electrode is designated for driving the mirror plate to an OFF state. The two electrodes can be disposed on the same side of the mirror plate but on opposite sides of the rotation axis of the mirror plate for driving the mirror plate to rotate in opposite directions. Alternatively, the two electrodes can be disposed on the opposite sides of the mirror plate, but on the same side of the rotation axis of the mirror plate for driving the mirror plate to rotate in opposite directions. The ON state and OFF state of the mirror plate can be defined by stops. The stops may be formed on substrate(s), hinge structures holding the mirror plates of the micromirror device and/or a desired location within the micromirror device. Alternatively, the electrodes for the ON state and the OFF state can be used as stops, either individually or in combination, or in combination with other component(s), such as substrate(s) of the micromirror device. The OFF state angle and the ON state angle are preferably different.

摘要： A method of removing contaminant particles in newly fabricated field emission displays. According to one embodiment of the present invention, contaminant particles are removed by a conditioning process which includes the steps of: a) driving a anode of a field emission display (FED) to a predetermined voltage; b) slowly increasing an emission current of the FED after the anode has reached the predetermined voltage; and c) providing an ion-trapping device for catching the ions and particles knocked off, or otherwise released, by emitted electrons. In this embodiment, by driving the anode to the predetermined voltage and by slowly increasing the emission current of the FED, contaminant particles are effectively removed without damaging the FED. The present invention also provides a method of operating FEDs to prevent gate-to-emitter current during turn-on and turn-off. In this embodiment, the method comprises the steps of: a) enabling the anode display screen; and, b) enabling the electron-emitters after the anode display screen is enabled. In this embodiment, by allowing sufficient time for the anode display screen to reach a predetermined voltage before the emitter is enabled, the emitted electrons will be attracted to the anode.

摘要： A flat panel display (500 or 700) contains a faceplate structure (510 or720), a backplate structure (511 or 730) coupled to the faceplate structure, and a plurality of spacers (501-503, 601, or 701-707) situated between the faceplate and backplate structures. The faceplate structure is formed with a faceplate )721) and a light emitting structure (722). The backplate structure is formed with a backplate (731) and an electron emitting structure (732). The core of each spacer is a spacer body (602 or 757). A face electrode (501a-503a, 203, 604, or 771-778) overlies the spacer body of each spacer. A common bus structure (504 or 723) electrically connects the face electrodes, thereby enabling charge built up on any particular spacer to be distributed among all the spacers.

摘要： Excess emitter material (52B) is removed in multiple steps during the fabrication of an electron-emitting device. A structure is initially provided in which a dielectric layer (44) overlies a non-insulating region (42), control electrodes (80 or 46/80) overlie the dielectric layer, openings (48/50) extend through the control electrodes and dielectric layer, electron-emissive elements (52A) formed with emitter material are situated in the openings, and an excess layer (52B) of the emitter material overlies the control electrodes and the dielectric layer. Portions of the excess emitter material overlying the dielectric layer in the spaces between the control electrodes are initially removed, preferably with etchant that directly attacks the emitter material. Portions (52C) of the excess emitter material overlying the control electrodes above the electron-emissive elements are subsequently removed to expose the electron-emissive elements.
