Abstract

PURPOSE:To improve luminous intensity while reducing cost by eliminating a thin film electrode on a display pattern. CONSTITUTION:A conductive thin film of aliminum or the like is formed on a light transmitting insulation substrate while forming wiring and display electrodes 2 and 2' through photoetching. The display electrodes 2 and 2' are so formed that a thin film electrode is kept so that the periphery of a display pattern may be generally about 0.1-0.5mm. while completely removing the electrode part corresponding to the display pattern through photoetching. Next, an insulation layer 3 is formed so as to be partly on the display electrodes 2 and 2' while removing the display part. Further, a phosphor material 4 is evenly applied and formed so as to cover the whole display pattern while being partly on the display electrodes 2 and 2' formed on the outer periphery of the display pattern. Subsequently, the grids 5 and a filament 6 are by turns constituted while tightly sealing the whole.

(5) Description of Effects The fluorescent display tube described above does not have honeycomb or stripe-like electrodes in the display pattern as in conventional structures. However, since the fluorescent material is formed in contact with a non-transparent conductive electrode formed on the outer edge of the display pattern, the potential from external sound is applied to the fluorescent material via this outer edge electrode. . Therefore, it is emitted from the filament and appears on the sound surface.1. Tayukisha - Fluorescent substance flows to the external terminal through the outer edge electrode while causing estrus. This phenomenon, which was unexpectedly confirmed by experiment, is thought to be possible because the fluorescent material normally used in fluorescent display tubes has semiconductor characteristics. Since this method does not have a non-light-transmitting thin film electrode in the display pattern area, it naturally has the effect of improving the light emission intensity, and it is also very advantageous in terms of cost since it is not necessary to manufacture fine structures such as honeycombs or stripes. You can get the following effect.
