What do you mean by the contrast of the projector? What criteria should be used when purchasing a projector? Today I will share with you, what is the function of the contrast of the projector?
1. What is the contrast ratio
Refers to the light and dark areas in an image contrast between the brightest white and the darkest black different brightness levels of measurement, the greater the difference range represents the contrast, the greater the difference on behalf of the contrast, the smaller the smaller the range, good contrast ratio of 120:1 can easily show vivid, rich color, when the contrast ratio is as high as 300:1, can support the color of each order. But the ratio suffers from the same difficulties as brightness, and there is no set of effective and impartial criteria for measuring the ratio, so the best way to recognize it is to rely on the user's eyes.
In simple terms, contrast is the ratio of the brightness of the same point on the screen at its brightest (white) to its darkest (black). So what does contrast do?
2. Effect of contrast
Under the reasonable brightness value, the higher the contrast, the more color levels can be displayed on the screen, the more vivid the picture will be, and the better the quality of the natural screen will be, which can make the video content more three-dimensional.
So that's what contrast means and what contrast does. The higher the contrast of the projector, the more stereoscopic the figure becomes, especially in a darkroom! Projector contrast ratio comparison video is down below.
