    • PURPOSE: A laser CRT is provided to reduce manufacturing costs and equipment costs without lowering the life of the CRT by preventing electrical discharge between flanges, a laser target and members connected to the laser target at the same time that electric circuits connected to a cathode are grounded. CONSTITUTION: A high voltage application part(7) passes through a vacuum bulb(1) with a predetermined distance from metal flanges(5,6). A laser target(3) is electrically insulated from the metal flanges, and is connected to the high voltage application part through a conductor(9) positioned within the bulb. Two shield electrodes(11,12) are installed in a space between a bulb wall, the flanges, the high voltage application part and the conductor, are respectively coupled to the high voltage application part and the flanges, and are extended toward each other to prevent electrical discharge between the flange and the high voltage application part and between the flange and the conductor.

    • PURPOSE: A projection device is provided to increase the contrast of images formed on a predetermined part of a background region, in order to improve the resolution of the device. CONSTITUTION: A projection device includes a projection member(6,7), at least one laser CRT(1), and at least one fluorescent CRT(2). The projection member(6,7) projects images on a CRT or an outside screen. At least one laser CRT(1) is arranged so as to illuminate on the same screen(4). Also, at least one fluorescent CRT(2) is also arranged so as to illuminate on the same screen(4). The fluorescent CRT(2) is further operated to form an image of big size with low resolution while the laser CRT(1) is operated to form an image of small size with high resolution.
    • 目的:为了提高设备的分辨率,提供投影装置以增加在背景区域的预定部分上形成的图像的对比度。 构成:投影装置包括投影部件(6,7),至少一个激光CRT(1)和至少一个荧光CRT(2)。 投影部件6,7在CRT或外部屏幕上投影图像。 至少一个激光CRT(1)布置成在相同的屏幕(4)上照亮。 此外,还布置至少一个荧光CRT(2)以便在同一屏幕(4)上照亮。 荧光CRT(2)进一步操作以形成具有低分辨率的大尺寸图像,同时操作激光CRT(1)以形成具有高分辨率的小尺寸图像。

    • PURPOSE: A method and laser CRT manufactured by such method is provided to reduce diameters of orifices of modulators and improve resolution of laser CRT. CONSTITUTION: A laser CRT comprises a cathode(1); modulators(2a,2b) having orifices(3a,3b) for forming beams from electrons emitted from the cathode; and a beam direction unit for allowing the beam formed by orifices of modulators to be directed toward a laser screen(7) of the CRT. A method for improving resolution of laser CRT comprises the first step of forming electron beam from electrons emitted from a cathode; the second step of allowing the beam to be directed toward a laser screen so as to excite radiated energy; the third step of forming one or more separated electron beams from electron beams emitted from a single cathode by using one ore more modulators; and the fourth step of allowing the laser beam to be directed toward the laser screen so as to excite one or more laser beams.
    • 目的:提供通过这种方法制造的方法和激光CRT,以减少调制器的孔的直径并提高激光CRT的分辨率。 构成:激光CRT包括阴极(1); 具有用于从阴极发射的电子形成光束的孔口(3a,3b)的调制器(2a,2b) 以及用于使由调制器的孔形成的光束朝向CRT的激光屏(7)的光束方向单元。 用于提高激光CRT分辨率的方法包括从阴极发射的电子形成电子束的第一步骤; 允许光束被引导到激光屏幕以激发辐射能量的第二步骤; 通过使用一个或多个调制器从单个阴极发射的电子束形成一个或多个分离的电子束的第三步骤; 以及允许激光束被引导到激光屏幕以便激发一个或多个激光束的第四步骤。
