Whether it is the traditional halogen bulb projection, or the use of LED or laser light source intelligent projection, brightness is always a key indicator of its performance: a projector with ample brightness projects bright, colorful, rich details, otherwise the screen is dim, watching Experience is bad. Based on the important impact of brightness on image quality, the projection circle has always been said to have "a brightness of a penny" and other arguments, some bad businesses is also using this point, through the exaggerated value of the projector brightness to deceive consumers to pay.
Why is the imaginary brightness not punished?Projector brightness is divided into maximum brightness, peak brightness, ANSI lumen brightness, and even some manufacturers own units, but in addition to ANSI lumens (International Standards Unit) reference value is relatively large, other units have almost no meaning, virtual brightness It is the use of numerical differences between different brightness units for word games. Although this does not violate the law, it actually hurts the user's actual experience. For example, with a projector with a peak brightness of 4,000, the projected picture may not be visible at all.
How to avoid being pitted?The first is to look for big brands, followed by the brightness unit before buying. Of course, the last and most important point is still the actual measurement - the brightness is not the higher the better, and the coordination with the ambient light is also very important, the brightness is suitable , you can know when you play the video.
Written at the end:In the current home environment, projectors with ANSI brightness between 2000 and 3500 are preferred. If the smart micro-projection with LED light sources is used, the brightness is preferably over 1000 ANSI lumens; projectors above 4000 brightness are not recommended for home use. When the user purchases, too high brightness will not only increase the purchase cost but also cause visual fatigue.
