摘要:
A drive circuit for an image display device capable of permitting anode lead-out wires to be led out without using a three-dimensional wiring structure and an image free of color bleeding to be displayed. Two-divided first and second anode electrodes are arranged opposite to stripe-like gate electrodes and are alternately driven. During driving of the first anode electrodes, cathode electrodes are scanned and only gate electrodes opposite to the anode electrodes are fed with image data. Then, the second anode electrodes are driven and scanning is likewise carried out. Thus, an image for one frame is displayed. Electrodes arranged on both sides of each of the anode electrodes and gate electrodes in a manner to be adjacent thereto have a potential kept at a ground level.
摘要:
An image display device including a field emission element capable of preventing diffusion of electrons to be impinged on a display section. An anode substrate is provided thereon with a phosphor-deposited display section and a cathode substrate is provided thereon with field emission elements including cathode conductors, emitter electrodes and gate electrodes. The cathode conductors and gate electrodes are formed into a stripe-like shape and arranged so as to intersect each other to form a matrix. A stripe-like diffusion prevention electrode is arranged between each adjacent two of the gate electrodes. The emitter electrodes selected by the gate electrodes and cathode conductors emit electrons. The diffusion prevention electrodes on both sides of each of the gate electrodes selected are applied thereto a voltage lower than a voltage of the gate electrodes, so that the electrons may be impinged on the display section required without diffusion, to thereby permit picture cells required to emit light.
摘要:
A field emission type fluorescent display device capable of exhibiting high luminescence under a low voltage while minimizing leakage luminescence and color mixing, to thereby improve display quality. An anode and a field emission cathode are arranged opposite to each other and the cathode is divided into a plurality of unit regions in a matrix-like configuration, which are matrix-driven, resulting in a display being selectively carried out. The unit regions each are divided into a plurality of subregions and the cathode and anode are divided into a plurality of strip-like electrodes perpendicular to each other, respectively. The strip-like electrodes each correspond to each of subregions and are commonly connected to each other at every second interval. Also, a focusing electrode may be arranged between the gate and the anode so as to surround the unit regions.

摘要:
In a field emission type device, pairs of patch-shaped cathode electrodes 3 are disposed on each of cathode electrodes 2 with an insulation in the line direction. Even-numbered patch-shaped gate electrodes 3 are connected to a first gate lead electrode GT1 on a line perpendicular to the cathode electrodes 2. Odd-numbered patch-shaped gate electrodes are connected to a second gate lead electrode GT2. An anode electrode 8 with a phosphor is disposed opposite to the patch-shaped gate electrodes 3. The first gate lead electrode GT1 and the second gate lead electrode GT2 are alternatively driven. The voltage of one of the first gate lead electrode GT1 and the second gate lead electrode GT2 is set to a ground level. Image data is supplied to cathode lead electrodes Cl to Ck. The voltage of the patch-shaped gate electrodes disposed adjacent to a patch-shaped gate electrode 3 that is driven is set to the ground level. Thus, electrons emitted are focused.

A fluorescent display apparatus having a plurality of anodes linearly arranged and divided into consecutive several groups each containing the same number of anodes. Each of the anodes disposed in corresponding positions of the respective anode groups is electrically connected in parallel, and a control grid is provided in each of the anode groups in an opposed relation. A particular anode representing the value of an input signal is illuminated by energizing one of the anodes in the respective anode groups and one of the control grids.
