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： In a flat-panel display structure having a spacer with laterally segmented face electrodes, one embodiment of the present invention defines the length of the laterally segmented face electrode sections to minimize zero current shift variation in electron trajectories. Advantageously, the present embodiment of the invention prevents image quality degradation. In one embodiment, values for variation in the uniformity of and dicing tolerance are combined to calculate a design optimum for the length of laterally segmented face electrodes. Zero current shift variation from fluctuations in wall resistance falls off with the length of laterally segmented face electrodes. Zero current shift due to first order angular alignment during dicing varies linearly with the dashed electrode length. In one embodiment of the present invention, an optimal value is calculated by combining these effects to minimize zero current shift. Advantageously, in one embodiment, the electrode segments are individually testable.

摘要： The intensity at which electrons emitted by a first plate structure (10) in a flat-panel display strike a second plate structure (12) for causing it to emit light is controlled so as to reduce image degradation that could otherwise arise from undesired electron-trajectory changes caused by effects such as the presence of a spacer system (14) between the plate structures. An electron-emissive region (20) in the first plate structure typically contains multiple laterally separated electron-emissive portions (201 and 202) for selectively emitting electrons. An electron-focusing system in the first plate structure has corresponding focus openings (42P1 and 42P2) through which electrons emitted by the electron-emissive portions respectively pass. Upon being struck by the so-emitted electrons, a light-emissive region (22) in the second plate structure emits light to produce at least part of a dot of the display's image.

摘要： 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.
