What is the contrast ratio ?
When you plan to buy a projector, in addition to the resolution and projection brightness you will need to pay attention to, there is a very common and important parameter - the contrast ratio. However, few projector beginners pay attention to the parameter. So let's see about the specifics of it.
First of all, what is the contrast ratio?
Put it simply, the contrast ratio is the ratio of the luminance of the brightest shade (white) to that of the darkest shade (black) that the system is capable of producing. Generally speaking, the greater the contrast ratio, the more gradations from black to white, the richer the color performance of the projector.
Second, what is the role of the contrast ratio?
For home projectors, the contrast ratio of the picture is a very important parameter. This is because the contrast ratio has a great impact on the visual effect of the image presented. Generally speaking, the greater the contrast ratio, the clearer and more brilliant the image is, and the more vivid and colorful the projected image is; on the contrary, the smaller the contrast ratio, the grayer and darker the image is, the less clear the image is, which makes users feel that their eyes are blocked by fog.
In addition, high contrast ratio has a great impact on the clarity, detail, and gray level of the projected image.
To sum up, when you buy a projector, it's always a good idea to go for high contrast.
