    • An evacuated envelope has a rectangular display section and a gun section at one side of the display section. The display section includes rectangular front and back walls in closely spaced, substantially parallel relation, and a plurality of spaced, substantially parallel support walls between the front and back walls forming a plurality of parallel channels. The gun section extends across one end of the channels and includes gun structure which will selectively direct one or more electron beams along each of the channels. In each of the channels is a beam guide which confines the electrons of the beam but permits selective deflection of the electron beam out of the guide toward a phosphor screen on the inner surface of the front wall. The beam guide includes spaced, parallel conductors on the inner surface of the back wall extending transversely across the channels and a plurality of electrodes on the surfaces of walls which extend from the back wall toward the front wall. The electrodes on each surface of the walls are arranged in spaced, parallel rows extending longitudinally along the channel. Electrical potentials are applied to the electrodes which create electrostatic fields between the electrodes in the two rows as well as between the electrodes on adjacent walls. These electrostatic fields create forces which confine the electrons in a beam which flows longitudinally along the channel. Potentials applied to the electrodes on the back wall cause the beam to be deflected out of the beam guide toward the front wall.
    • 抽真空的信封在显示部分的一侧具有矩形显示部分和枪部分。 显示部分包括紧密间隔的基本上平行的矩形前壁和后壁,以及形成多个平行通道的前壁和后壁之间的多个间隔开的基本平行的支撑壁。 喷枪部分延伸穿过通道的一端,并且包括可以沿着每个通道选择性地引导一个或多个电子束的枪结构。 在每个通道中的是光束引导件,其限制光束的电子,但允许电子束从引导件中选择性地偏转到前壁的内表面上的荧光屏。 梁引导件在后壁的内表面上横向延伸穿过通道,并且在壁的表面上从后壁向前壁延伸的多个电极包括间隔开的平行导体。 壁的每个表面上的电极以沿通道纵向延伸的间隔开的平行排布置。 电极被施加到在两行中的电极之间以及相邻壁上的电极之间产生静电场的电极。 这些静电场产生将电子限制在沿通道纵向流动的光束中的力。 施加到后壁上的电极的电位使得光束从光束引导件朝向前壁偏转。

    • An evacuated envelope has a rectangular display section and a gun section at one edge of the display section. The display section includes front and back walls which are generally rectangular, in closely spaced, parallel relation, and a plurality of spaced, parallel support walls between the front and back walls forming a plurality of parallel channels. The gun section extends across one end of the channels and includes therein gun structure which will direct electrons into the channels. In each of the channels is a beam guide which confines the electrons in a beam and guides the beam along the length of the channel. The beam guide also includes means for selectively deflecting the electron beam out of the guide at selective points along the guide so that beam will impinge upon a phosphor screen along the inner surface of the front wall. In each of the channels is a scanning deflector which deflects the path of the beam as it passes from the guide to the phosphor screen so that each of the beams will scan a portion of the phosphor screen.
    • 抽真空的信封在显示部分的一个边缘处具有矩形显示部分和枪部分。 显示部分包括大致矩形的紧密间隔的平行关系的前壁和后壁,以及形成多个平行通道的前壁和后壁之间的多个间隔开的平行支撑壁。 枪部分延伸穿过通道的一端并且包括其中将电子引导到通道中的枪结构。 在每个通道中是将电子限制在光束中的光束引导件,并沿着通道的长度引导光束。 光束引导还包括用于在沿着引导件的选择点处选择性地将电子束偏离引导件的装置,使得光束将沿着前壁的内表面撞击在荧光屏上。 在每个通道中是扫描偏转器,当光束从引导件通过到荧光屏时使光束的路径偏转,使得每个光束将扫描荧光屏的一部分。
