目前因为投影机用户在选购投影机时容易走入一个误区:盲目追求亮度,认为亮度越高越好。 亮度一般采用ANSI流明来表示,ANSI流明是美国国家标准化协会制定的测量投影机光通量的方法,它是将屏幕分成“田”字形,然后测量九个交叉点的亮度,乘以面积,再求得九点的平均值,即 Currently, projector projectors are easy to enter into a misunderstanding when choosing a projector: the blind pursuit of brightness, the higher the brightness, the better. ANSI lumens brightness is generally expressed as ANSI lumens is the United States National Institute of Standardization to develop projector luminous flux measurement method, which is the screen is divided into “Tian” glyph, and then measure the brightness of nine intersections, multiplied by the area, and then find The average of nine o’clock, that is
