    • An image display apparatus comprising an insulating substrate (1) having electron sources (13) controlled by X-Y matrix electrodes (10, 11) and a face plate (4) coated with a phosphor material in opposed relationship with the substrate is disclosed. An electron source at each intersection of the X-Y matrix control electrondes is made up of a plurality of cold cathodes (2) connected to an X-control electrode (10) and a plurality of gate electrodes (3) connected to a Y-control electrode (11) opposed to the cold cathodes in the same plane, and the electron source is formed on the substrate surface on other than the X- and Y-control electrodes. A voltage applied between the cold cathodes and gate electrodes arranged in opposed relations on the same surface causes a high electric field of about 10⁷ V/cm at the forward end of the cold cathodes leading to an electron emission. A part of electrons thus emitted enters the anodes directly. Another part of electrons flow into the opposed gate electrodes to generate secondary electrons in the surface of the gate electrodes. The secondary electrons thus generated are accelerated by the positive voltage (anode voltage) applied to the phosphor surface of the opposed face plate and bombarded on the phosphor material, which is thus illuminated.
    • 公开了一种图像显示装置,包括具有由X-Y矩阵电极(10,11)控制的电子源(13)和涂覆有与衬底相对的荧光体材料的面板(4)的绝缘衬底(1)。 XY矩阵控制电极的每个交叉处的电子源由连接到X控制电极(10)的多个冷阴极(2)和连接到Y控制电极的多个栅电极(3)组成 (11)与同一平面中的冷阴极相对,并且在X和Y控制电极之外的基板表面上形成电子源。 施加在相同表面上相对关系的冷阴极和栅电极之间的电压在冷阴极的前端产生约10 7 V / cm的高电场,导致电子发射。 这样排出的电子的一部分直接进入阳极。 电子的另一部分流入相对的栅电极,以在栅电极的表面产生二次电子。 这样产生的二次电子被施加到相对的面板的荧光体表面的正电压(阳极电压)加速,并在被照射的磷光体材料上被轰击。
