经常性地开关显示器,会减少它的寿命。而且研究表明,“没有明确的证据”能证明普通的电磁场辐射会导致癌症、神经行为和生育及生长失常问题(资料来源:美国《科学》杂志)。所以,现在有一个普遍存在的错误观点,认为应该让计算机显示器总是开着,才能更好地保养显示器。这样做是弊大于利。 1.显像管寿命:显示器的寿命取决于显像管的寿命,目前看来,显像管是显示器中最昂贵的部件。如果是显像管坏了,需要替换,该显示器就不值得修理了。无论屏幕显示的是何内容,显像管的亮度寿命为10000～15000个工作小时,10000个小时就是一年多一点儿。如果晚上仍不关显示器,它的寿命就 Switching the monitor on and off often will reduce its life. And research shows that “there is no clear evidence” that ordinary radiation from the electromagnetic field can cause cancer, neurobehavior and maternal and growth disorders (Source: Science). So, now there is a ubiquitous misconception that the computer monitor should always be on for better maintenance of the monitor. This is more harm than good. 1. CRT life: the life of the monitor depends on the life of the CRT, at the moment, the CRT is the most expensive part of the monitor. If the tube is broken and needs to be replaced, the monitor is not worth repairing. No matter what the screen shows, the brightness of the tube life expectancy of 10,000 to 15,000 working hours, 10000 hours is a little more than a year. If the monitor is still off at night, its life will be
