Abstract: PROBLEM TO BE SOLVED: To constitute a device to match various back panel thicknesses by attaching a cathode reinforcing member, which is made from a metallic material, such as glass, titanium, or a nickel-iron alloy, to the outside surface of a cathode. SOLUTION: A cathode reinforcing member 170 made from a metallic material, such as glass, titanium, or a nickel-iron alloy, is fixed to the outside surface of a cathode 130 and has a coefficient of thermal expansion substantially equal to that of the cathode 130. By attaching the cathode reinforcing member 170 to the outside surface of the cathode 130 after formation of the cathode 130, a device can be constituted to match an appropriate thickness of a backplate 185 and an overall thickness.

Abstract: Method for operating a field emission display (10) and a field emission display (10) that has a plurality of column conductors (17, 18, 19) on which electron emitter structures (24) are disposed. Column conductor driver circuits (47, 48, 49) are coupled to respective column conductors (17, 18, 19) and row conductor driver circuits (37, 38, 39) are coupled to respective row conductors (27, 28, 29) to form sub-pixels (50, 57, 58, 60, 67, 68, 70, 77, 78). The column conductor driver circuits (47, 48, 49) and the row conductor driver circuits (37, 38, 39) cooperate to cause the electron emitter structures (24) to emit electrons. The column conductor driver circuits (47, 48, 49) measure a signal change on at least one of the column conductors and thereby adjusts the operating state of the electron emitter structures (24) are adjusted in accordance with the comparison results.

Abstract: Method reducing cross-talk between adjacent column conductors in a field emission display (10) that has a plurality of column conductors (17A, 17B, 17C, 18A, 18B, 18C) on which electron emission structures (24) are disposed. The field emission display (10), also includes a plurality of row conductors (27, 28, 29). Cross-talk is prevented by ensuring that adjacent conductors are not in an active state at the same time.

Abstract: Method and structure for reducing crosstalk between adjacent column conductors in a field emission display (50) that has a plurality of column conductors (57, 59) on which electron emission structures (64) are disposed. The field emission display (50) also includes a plurality of row conductors (67, 68). A field termination structure (58) is formed between adjacent column conductors. The field termination structure (58) attenuates a voltage glitch created by a switching column conductor, thereby preventing the voltage glitch from affecting adjacent nonswitching column conductors.

Abstract: A field emission display (100) includes a cathode plate (110) having a plurality of electron emitters (114), and anode plate (122) having an anode (124) connected to a potential source (126), and an anode voltage pull-down circuit (127) having an input (106) and an output (104). Output (104) is connected to anode (124), and input (106) is connected to potential source (126). Preferably, anode voltage pull-down circuit (127) causes an anode voltage (120) at anode (124) to drop to about ground potential prior to generation of a discharge current by electron emitters (114) for neutralizing positively electrostatically charged surfaces (137, 138) within field emission display (100).

Abstract: A field emission device (100) having an electron emitter (101), for emitting electrons, an extraction electrode (102) proximally disposed with respect to the electron emitter (101), an anode (103) for collecting some of any emitted electrons is formed. Anode (103) is distally disposed with respect to the electron emitter (101). A transient current source (110) is operably coupled between the electron emitter (101) and a reference potential (107). Transient current source (110) provides a transient current to the electron emitter (101) to enhance response time for emission of electrons from the electron emitter (101) of the field emission device (100). A controlling input line (111) is provided for current controlling signals to the transient current source (110) with the controlling input line (111) being operably coupled to the transient current source (110).
