Recently, glass blocks are often used for part of the building wall, and have good effect on lighting and decoration.The glass block is originally clear and hollow. If only we set a pair of electrodes and pack proper gases in it, can turn it a discharge tube easily. We have packed Hg and Ne gases in it to make it a multicolored discharge tube and have tried to develop multicolored discharge display serving for a lighting wall.We worked together and carried out the study especially about next three points, that is, (1) design and manufacture of glass blocks, (2) development and trial manufacture of lighting circuits, (3) formation of the display panel.The report for results describes about the above points and its summary is following. (1) We have formed a display panel with 5x 7 dots by 35 glass blocks and could express the alphabet, Arabic numeral, katakana and symbols in two colors, red and blue. (2) The negative glow in the panel with blocks shaping Z was covered by the anode of the next dot perfectly. (3) The negative glow in the square block could be covered too by the blind in front of the cathode. In result, the panel can express to both sides, inside and outside. (4) The luminous color is considerably vivid. That is, the red is (x=0.5, y=0.33) and the blue is (x=0.22, Y=0.24). (5) The brightness is a little over one hundred nt, but it is not enough. We must study more the structure of electrodes to obtain the brightness of hundreds nt. (6) The luminescent efficiency is very low about 0.6 lm/W. We must improved this hereafter.

近年来，玻璃砖常用于建筑物的部分墙体，具有良好的采光和装饰效果。只要我们在它里面装上一对电极和适当的气体，就可以很容易地把它变成一个放电管。我们在其中填充了Hg和Ne气体，使其成为多色放电管，并尝试开发用于照明墙的多色放电显示器。我们共同努力，特别是对以下三点进行了研究：（1）玻璃块的设计和制造，（2）照明电路的开发和试制，（3）显示面板的形成。结果报告描述了上述要点，其摘要如下。(1)我们已经形成了一个显示面板与5x 7点由35玻璃块，可以表示字母，阿拉伯数字，片假名和符号的两种颜色，红色和蓝色。(2)Z字形块板中的负辉光被下一个点的阳极完全覆盖。(3)方形块中的负辉光也可以被阴极前面的盲板覆盖。因此，面板可以向内侧和外侧的两侧表达。(4)发光的颜色相当鲜艳。也就是说，红色是（x=0.5，y=0.33），蓝色是（x=0.22，Y=0.24）。(5)亮度是一百多新台币一点，但还不够。要想获得几百纳米的亮度，还需要进一步研究电极的结构。(6)发光效率很低，约为0.6lm/W。今后我们必须改进这一点。
