机械电子部第十四研究所研制成功多色LEE 大屏幕显示系统。屏幕最大面积为64m~2,可以显示红、绿、橙、黑四种色彩。屏幕由一台微机控制、从微机 CRT 接口发出数据信息、色彩信息、行同步、帧同步等信号,同时送到 CRT 和大屏幕的控制系统中同步显示。大屏幕为行业扫描控制,一幅画面扫描时向为1/60s。系统的发光单元(LEE)由30×30×36mm 的铝壳、COB—LED 阵列散射板、底座组成,安装在500×500mm 的铝板上构成一个显示组件。大屏幕又由若干显示组件安装在一个大型框架上组成。该系统使用电压380V。
Fourteenth Institute of Mechanical Electronics developed a multi-color LEE large-screen display system. The maximum screen area of 64m ~ 2, you can display red, green, orange, black four colors. Screen by a microcomputer control, issued from the computer CRT interface data information, color information, line synchronization, frame synchronization and other signals at the same time sent to CRT and large-screen control system simultaneously display. Large screen for the industry scanning control, a picture scanning to 1 / 60s. The system’s light-emitting unit (LEE) consists of a 30 × 30 × 36mm aluminum housing, a COB-LED array diffuser, and a base mounted on a 500 × 500mm aluminum plate to form a display unit. Large screen by a number of display components installed in a large frame on the composition. The system uses a voltage of 380V.
