DJS130计算机在天津无线电技术研究所研制出来后,据反应,该机控制面板上用作19位指示灯的发光二极管亮度不够,看不清。亮度不够,固然是发光二极管功率所限,但另一方面,在滤色有机玻璃的使用上也欠考虑。DJS130计算机,在铝面板外装璜了一个背面涂了漆的无色有机玻璃面板,黑底白色符号(有的厂家用黑底红色符号或用淡灰底浅兰符号)标志。为了增加油漆与有机玻璃的附着 DJS130 computer developed in Tianjin Institute of Radio Technology, according to the reaction, the aircraft control panel for 19-bit light-emitting diode brightness is not enough, not clear. Not enough brightness, of course, is limited by the power LED, but on the other hand, the use of color filter plexiglass are also not considered. DJS130 computer, outside the aluminum panel decorated with a painted colorless plexiglass panel on the back, black and white symbols (some manufacturers with a black or red light gray light blue symbol). In order to increase the adhesion of paint and plexiglass
