Abstract: Seal material bars and methods for forming seal material bars, a seal material frame, and method for forming a flat panel display using the same. Bars of seal material (1101-1104) are made by extruding a mixture of glass frit and organic compound. In one embodiment, the glass frit bars have joining features (1111-1118) formed in them. Ceramic material is also extruded so as to form seal material bars. The seal material bars are placed between the backplate and the faceplate and glass frit slurry may be placed between adjoining seal material bars. A heating step melts the seal material so as to form a seal interior region. Alternatively seal material bars may be joined in a first step to form a seal material frame. A further embodiment comprises extrusion of a hollow rectangular shape of seal material which is cut crosswise into integral seal material frames.

Abstract: A flat-panel display contains a pair of plate structures (40 and 42) coupled together to firm a sealed enclosure. A spacer (44) is situated in the enclosure for resisting external forces exerted on the display. The spacer is formed with a main spacer portion (60), typically shaped like a wall, and a face electrode (66) situated over a face of the main spacer portion. The face electrode causes electrons moving from one of the plate structures to the other to be defected in such a manner as to compensate for other electron deflection caused by the presence of the spacer. The face electrode is divided into multiple laterally separated segments (661 - 66N) to improve the accuracy of the compensation along the length of the spacer. In fabricating the display, a masking step is typically utilized in defining the widths of the segments of the face electrode.

Abstract: A field emission display (700) having an improved operational life. In one embodiment, the field emission display (700) comprises a plurality of row lines (230), a plurality of column lines (250), and a plurality of electron emissive elements (40) disposed at intersections of the plurality of row lines (230) and column lines (250), a column driver circuit (740) and a row driver circuit (720). The column driver circuit (740) is coupled to drive column voltage signals over the plurality of column lines (250); and the row driver circuit (720) is coupled to activate and deactivate the plurality of row lines (230) with row voltage signals. According to the present invention, operation life of the field emission display is 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 (770). The row driver circuit (720), upon receiving the SLEEP signal (770), drives a sleep-mode voltage over the row lines (230) to reverse-bias the electron emissive elements.

Abstract: A method of removing contaminant particles in newly fabricated filed emission displays. Contaminant particles are removed by a conditioning process which includes the steps of: a) driving an anode (20) 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 (40). 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. A method of operating FEDs is also provided to prevent gate-to-emitter current during turn-on and turn-off, which comprises the steps of: a) enabling the anode display screen (20); and b) enabling the electron-emitters (40) after the anode display screen is enabled. By allowing sufficient time for the anode display screen to reach a predetermined voltage before the emitter is enabled, the emitted electrons (40) will be attracted to the anode (20).

Abstract: A circuit for time multiplexing a voltage signal for controlling the color balance of a flat panel display (200). Within an FED screen, a matrix of rows (230) and columns (250) is provided and emitters are situated within each row-column intersection (100). Rows are sequentially activated during 'row on-time windows' by row drivers (220) and corresponding individual gray scale information (voltages) are driven over the columns by column drivers (240). Within each column driver, the present invention provides selection circuitry for driving a first voltage signal during a first part of the row on-time window and a second voltage during a second part of the row on-time window. The lengths of the first part and second part of the row on-time window can be adjusted for a given color, to adjust the color balance with respect to color.

Abstract: An electrode (12 or 30) of an electron-emitting device has a plurality of openings (16 or 60) spaced laterally apart from one another. The openings can be used, as needed, in selectively separating one or more parts of the electrode from the remainder of the electrode during corrective test directed towards repairing any short-circuit defects that may exist between the electrode and other overlying or underlying electrodes. When the electrode with the openings is an emitter electrode (12), each opening (16) normally extends fully across an overlying control electrode (30). When the electrode with the openings is a control electrode (30), each opening (60) normally extends fully across an underlying emitter electrode (12). The short-circuit repair procedure typically entails directing light energy on appropriate portions of the electrode with the openings.

Abstract: A circuit and method for controlling the brightness of a display screen implemented using a field emission display (FED) screen (200). In an automatic brightness adjustment embodiment, an ambient light sensor (580) supplies the brightness signal that changes in proportion to the light sensed. The FED screen brightness is increased in response to increases in the light sensor output and decreased in response to decreases in the light sensor output. Another embodiment uses the light sensor (580) for brightness normalization where the FED screen (200) is used as the reference light level and the FED screen brightness is compensated for due to variations caused by age and manufacturing differences. A manual brightness adjustment (override) and automatic brightness on/off switch are also provided.

Abstract: A flat-panel device is fabricated by a process in which a pair of plate structures (40 and 42) are sealed along their interior surfaces (40A and 42B) to opposite edges (44A and 44B) of an outer wall (44) to form a compartment. Subsequently, exterior support structure (64) is attached to the exterior surface of one of the plate structures (40) to significantly increase resistance of the compartment to bending. Exterior support structure (66) is normally likewise attached to the exterior surface of the other plate structure (42) after the sealing operation. The compartment is then typically pumped down to a high vacuum through a suitable pump-out port (46) and closed. By providing the exterior support structure at such a relatively late stage in the fabrication process, the need for using spacers to support the device against external forces is eliminated or substantially reduced while simultaneously avoiding severe fabrication difficulties that arise in attaching the exterior support structure before the sealing operation.
