摘要： A field emission display includes an array of emitter sites, a grid for controlling electron emission from the emitter sites, and a display screen. The field emission display also includes a control circuit for controlling the grid for preventing emission to grid. The control circuit includes a high impedance grid bias path, and a low impedance grid bias path. In addition, the control circuit includes a sensing-switching circuit for sensing an anode voltage at the display screen, and switching from the high impedance to the low impedance grid bias path upon detection of a threshold anode voltage. An alternate embodiment control circuit is configured to provide a programmable delay during enabling of the grid to insure that the display screen reaches the threshold voltage prior to electron emission. An alternate embodiment field emission display includes a focus ring that is controlled to prevent emission to grid.

摘要： A night vision device (NVD) includes a control circuit having an acceleration-responsive switch. When the NVD is in a generally horizontal use position, the acceleration-responsive switch enables a circuit allowing voltage to be applied to an image intensifier tube of the night vision device, so that night vision is provided. On the other hand, when the device is flipped up to a stowed position allowing the user of the device unobstructed natural vision, the acceleration-responsive switch senses the changed orientation of the gravitational acceleration vector, and turns off the image intensifier tube as well as other light-emitting sources of the night vision device. The acceleration responsive switch controls operation of voltage step-up circuit, which allows the NVD to be operated with a single one and on-half volt battery cell, and which also insures when it is turned off that not only is the image intensifier tube turned off, but also that all other possible sources of light emissions from the NVD are turned off.

摘要： An improved intensity control system for an intensified imaging system allows continuous viewing through an intensified imaging system while protecting saturated areas from the negative effects of overexposure. A micromirror array (MMA) is used in conjunction with associated optics to control the intensity incident on the image intensifier. Control circuitry determines if pixel intensity is above or below the preset threshold level. If above, the corresponding elements of the MMA array will deflect the incident light in that specific area thereby eliminating saturation of the pixels. The rest of the image is maintained for continuous viewing. A continuous feedback loop monitors the intensity levels of pixels and actively controls the incident light using the MMA.

摘要： A display apparatus for displaying pictures virtually instantaneously adopts a direct-heating type cathode of an impregnated structure, and includes a cathode ray tube having a dispenser cathode wherein a cathode material is filled in pores of a porous body and a porous heater is directly connected to the cathode material. A voltage generator of the apparatus produces a first voltage for driving the heater. A video signal supply portion supplies a video signal to the cathode, while a deflector deflects horizontally and vertically an electron beam generated from the cathode to produce a raster by scanning the fluorescent surface of the cathode ray tube. A flyback transformer generates a second voltage to be supplied to the anode and one or more grids of the cathode ray tube using a horizontal deflection output signal supplied from the deflector. With the described arrangement, an electron-emitting velocity of an electron gun reaches its maximum value within about one second after power is applied. Thus, the display apparatus can be adapted to an HDTV requiring high current density electron-emitting characteristics.
