光柱显示板是美国Burroughs公司发明的新型等离子体气体放电显示器件。该公司的注册商标是SELF-SCAN。光柱显示板(SELF-SCAN)是一种平板型的线性指示器,它以光柱的高度显示各种模拟量。器件所需功耗低(约3瓦),可提供优越的读出能力。各种仪器仪表,加工控制系统,汽车和飞机都可用光柱显示板作指示器。它的外形是细长的矩形(如图1所示),高103毫米、宽20毫米、厚4.5毫米。光柱由200根精细的阴极线组成,分辨率为O.5％。显示时光柱宽3毫米、呈橙红色、亮度为39.7尼特。
Bargraph display panel is the United States Burroughs invented the new plasma gas discharge display device. The company's registered trademark is SELF-SCAN. SELF-SCAN is a flat linear indicator that displays various analogs at the height of the beam. Low power consumption of the device (about 3 watts), can provide superior readout capability. A variety of instrumentation, process control systems, cars and aircraft can be used as a light bar display panel indicator. Its shape is a slender rectangle (shown in Figure 1), 103 mm high, 20 mm wide and 4.5 mm thick. The beam consists of 200 fine cathode wires with a resolution of 0.5%. Show time column width 3 mm, orange-red, brightness of 39.7 nits.
