Abstract: A compact pulsed optical source of near to ultraviolet wavelength energy adapted to be connected to an external power source. The optical source includes a device for emitting photons, apparatus for transforming photons into photoelectrons, apparatus for multiplying the photoelectrons, a lens, a phosphor coated anode, circuit apparatus for providing a pulsed electric signal and first and second biasing apparatus. The emitting device impinges photons on the photon transforming apparatus which accelerates electrons to the multiplying apparatus as pulses are received from the circuit apparatus which relates the multiplying apparatus to the transforming apparatus. With each pulse, a cloud of electrons is emitted from the multiplying apparatus and excites the phosphor coated anode thereby causing optical emission.

Abstract: A plurality of control plates is sandwiched between a cathode and a target to control the flow of charged particles such as electrons and ions between the cathode and the target. The cathode includes an elongated filament for generating charged particles such as electrons. A first electrode having a negative potential is positioned behind the filament with a second electrode having a positive potential interdigitated with the first electrode. Each control plate has a plurality of apertures formed therein which are effectively aligned with corresponding apertures on the other control plates. The aligned apertures form beam channels. The control plates have paired conductive electrodes thereon arranged at predetermined coded finger patterns. Voltages are selectively applied to the control plate electrodes by switching circuitry to focus the charged particles through the apertures associated with selective electrodes while simultaneously aborting the passage of charged particles through the apertures associated with the remaining electrodes. In this manner by selective switching control of the control plate a beam, or a plurality of beams, can be directed to a selected portion or portions of the target at the time.
Abstract translation: 多个控制板夹在阴极和靶之间,以控制阴极和靶之间的电荷和离子等带电粒子的流动。 阴极包括用于产生诸如电子的带电粒子的细长丝。 具有负电位的第一电极位于具有与第一电极交叉的正电位的第二电极的后面。 每个控制板具有形成在其中的多个孔,其与其它控制板上的对应的孔有效对准。 对准的孔形成束通道。 控制板在其上配置有成对的导电电极,其中预定的编码手指图案布置。 通过切换电路将电压选择性地施加到控制板电极,以将带电粒子聚焦通过与选择性电极相关联的孔,同时中止带电粒子通过与剩余电极相关联的孔。 以这种方式,通过控制板的选择性切换控制,光束或多个光束可以被定向到目标的选定部分或多个部分。

Abstract: An LCD display has a programmable backlight device that produces multiple different color fields from multiple different phosphor elements. The backlight device can be a low resolution FED device. The phosphor is applied by an electrophotographic screening process or direct electrostatic screening process. The FED device can further incorporate a wide gamut phosphor.

Abstract: An image display apparatus includes a face plate with a plurality of light-emitting regions, a rear plate with electron-emitting devices corresponding to the plurality of light-emitting regions, respectively, and a drive circuit that drives the electron-emitting devices. The drive circuit has a correction circuit that calculates a correction value evaluated by influence of emitted electrons from electron-emitting devices which correspond to light-emitting regions around the light-emitting region to be corrected, and corrects a signal input to the electron-emitting device corresponding to the light-emitting region to be corrected based on the correction value. The correction circuit has an adjustment circuit that adjusts the correction value based on variation of characteristics of the plurality of light-emitting regions. Therefore, an image display having improved correction performance and lesser display unevenness can be performed.
