Loud noise to achieve ultra-high contrast ratio? .Secret projection core technology.

Contrast is a measure of display products is one important indicator of performance. .Past two years, the contrast has become a large selling point theater projector information. .From last year's first LED 1080p projector's 10 million: 1, to 20 million: 1 contrast is constantly being refreshed. .Increasing numbers, these numbers can result in any changes? .<P Align=center sizcache="3" sizset="141"> </ P> <P> What is contrast ratio? .</ P> <P> contrast is the ratio of black and white images, from black to white gradient. .The larger the ratio, the gradient from black to white the more levels, the richer color expression, the more realistic projection screen, gorgeous. .Conversely, the smaller the contrast, color images with less than, the screen will show the effect of gray is not clear. .And contrast levels are an important part of quality, but relatively easy to quantify the contrast, and have a major impact on the level, so not too stringent, we believe that high contrast can also provide a better level. .</ P> <P> projector industry is currently in the contrast test method 2, one is full on / off contrast tests, which test the output of the projector screen and all black all white screen brightness ratio. .The other is the ANSI contrast, which uses ANSI standard test method to test contrast, ANSI contrast ratio test method of black and white color with 16 points, 8 the average brightness of white areas and black areas 8 the ratio between the average brightness is the ANSI .contrast. .It is because of these two different measurement methods, so different brands very different contrast values. .</ P> <P> how to achieve ultra-high contrast ratio? .</ P> <P> we mentioned above, the higher the contrast, the number of colors richer, and the corresponding projector color performance capability is more real and natural. .Therefore, this parameter in contrast to targeting individual households is particularly important theater projector. .Contrast is the home that the core parameters of the projector is not too much. .Then, hundreds of thousands of ultra-high contrast ratio of 1 How is this possible? .Today, we have chosen three different technology to achieve ultra-high contrast projector brands as we uncover the secrets of ultra-high contrast. .</ P> 1 2 3 4 <p> this navigation: </ p> <li class='cur'> No. 01: a comprehensive understanding of the contrast <li> Chapter 02: LED Projection how to achieve 10 million: 1? .<li> Chapter 03: The maximum contrast ratio 200,000: 1 gnaw achieve <li> Chapter 04: Real highest contrast.
