In fact, the brightness of the projection has always been a sensitive topic, and many users do not know too much about it. Today, the author told you about the story behind the brightness of the projector, hoping to bring help to friends who are about to buy projection.
Are all routines telling the story behind the brightness of the projector
First of all, to give you a few concepts of popular science, the brightness of the projector is divided into the maximum brightness, peak brightness and ANSI brightness. In simple terms, the maximum brightness is the average brightness of the screen in the brightest mode of the projector (brightness, contrast, and lamp mode are all adjusted to the maximum). Peak brightness refers to the maximum value that can be reached at a certain point on the screen in the brightest mode. ANSI brightness refers to the ANSI test standard. As such, ANSI brightness is more significant in everyday use.
Eight gray levels for test brightness and 13 illumination test points
If the brightness of a home projector is marked as 3,500 lumens, the user may think that it will reach 3,500 lumens in the daily viewing, but it is not. The 3500 lumens mean the peak brightness. The picture is not clear, so this value does not make sense to the user.
Friends who are concerned about our evaluation should note that whether they are home or commercial projectors, their actual ANSI brightness will be very difficult if they can reach 70% of the nominal brightness, and some products are even only nominally 50%. In other words, a nominal projection of 3500 lumens, the user actually uses only 2500 lumens to 1750 lumens. Look, it's full of routines.
The standard manufacturer of brightness is full of routines
In addition to the word games mentioned earlier, the other is the reason for the vacuity. Some projectors do not reach the nominal value even if the peak brightness, there is no doubt that this is the manufacturer's virtual target. In fact, in the era of light bulbs, the brightness of projectors was not uncommon. With the development of the industry and users becoming more and more knowledgeable, this situation is now much less, but it is not completely eliminated.
In the future, the brightness of the projector will become less and less
Said so much, I hope to help users buy projection, do not blindly believe the manufacturer's publicity, the best time to buy a machine to feel the brightness of the machine. In addition, with the advancement of the industry and the development of science and technology, there will be fewer and fewer virtual targets and routines in terms of projector brightness, and the most realistic situation will be presented to users.
