Development of Multicolored Discharge Display of Glass Block Type

近年来，玻璃砌块常被用作建筑墙体的一部分，具有良好的采光和装饰效果。玻璃砌块原本是透明中空的。只要在其中安装一对电极，并装入适当的气体，就可以很容易地把它变成放电管。我们将汞和氖气体装入其中，使其成为一个彩色放电管，并尝试开发用于照明墙的彩色放电显示器。我们共同努力，特别是在接下来的三个方面进行了研究，即：(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。结果报告描述了以上几点，其摘要如下。(1)我们用35块玻璃组成了一个5 × 7点的显示面板，可以用红蓝两种颜色表示字母表、阿拉伯数字、片假名和符号。(2) Z形块板的负辉光被下一个点的阳极完美覆盖。(3)正极前面的遮罩也可以遮住正极方块的负辉光。因此，面板可以表达到两侧，内部和外部。(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）。亮度略高于100毫特，但还不够。(6)发光效率很低，约为0.6 lm/W。我们以后必须改进这一点。

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.
