确保荧光显示管在良好工作下谋求降低功耗。阴极需提供充裕电流，这是栅耗得以降低的基础条件。选用高效荧光粉，谨防受污染变质和减小阳极电阻可降低板耗。栅极靠近板极，栅丝做细，屏蔽系数取小和去掉多余边框和栅丝可降低栅耗。在同等加热功率下增加氧化物阴极丝条数和涂层厚度，熔封工艺中避免涂层受损，在１０－５Ｐａ以上的真空环境中短暂高温还原与长时间电流激活相结合获得良好阴极活性，可降低阴极功耗。
Make sure the fluorescent display tube works well to reduce power consumption. The cathode needs to provide ample current, which is the basic condition for reducing the gate loss. Use efficient phosphors, beware of pollution and reduce the anode resistance can reduce board consumption. Gate close to the plate, the wire made thin, shielding factor to take small and remove the extra border and wire can reduce gate consumption. In the same heating power to increase the number of oxide cathode wire and coating thickness, sealing process to avoid damage to the coating, in the vacuum environment more than 10-5Pa transient high temperature reduction combined with prolonged current activation to obtain good cathode activity , Can reduce cathode power consumption.
