目前投影机市场上品牌繁多,机型各异。作为测试投影机性能的一个重要指标就是亮度输出。客户在选择机型时,比较最多的恐怕也就是亮度指标。但是对并不太熟悉投影技术的用户来说,可能会对亮度输出的测试方法和单位名称由来不甚了解。也许对亮度输出作一些必要的介绍会对未来的用户有所帮助。 At present, many brands on the projector market, different models. As a test projector performance is an important indicator of brightness output. Customers in the choice of models, I am afraid the most is the brightness index. However, for users who are not too familiar with projection technology, the test methods of luminance output and the name of the unit may not be well understood. Perhaps some of the necessary inputs to the brightness output will help future users.
