What is Contrast Ratio?
The contrast ratio is a measure of a display system, defined as the ratio of the luminance of the brightest color (white) to that of the darkest color (black) that the system is capable of producing. A high contrast ratio is a desired aspect of any display, although there is no industry standard for measurement of contrast ratio, so comparing the contrast ratio of one brand with another may not yield valid results. Contrast ratio does not measure color range or color accuracy. Contrast ratio is basically a technical term for how realistic the colors and brightness is, pretty much determining how realistic in general the picture is. Some manufacturers of projectors or TVs will use a combination of these two tests in different phases of testing to inflate their contrast ratio. Contrast Ratio is generally defined as the ratio of the contrast measurement between the brightest color (white) and the darkest color (black) in a scene.

How important is Contrast Ratio

Contrast ratios have improved, but the gains have been modest. Manufacturers have, however, made great strides in the tricks they employ to arrive at ever more astronomical contrast ratios. TV contrast ratio is possibly the biggest misleading feature that you can use when comparing HDTV’s because even though a contrast ratio might be reported as identical between models, the actual contrast might be different. Dynamic contrast ratios are often quoted with new televisions. There have been a number of breakthroughs recently with contrast ratio, and who knows how long this will last, but recently there have been OLED (Organic LED) televisions manufactured by Sony and Samsung that claims to reach 1,000,000:1 contrast ratio. Even more to the point, a high contrast ratio really only matters when there is significant dark picture content, like you see in some movies. A more-representative method is the ANSI contrast ratio measurement, which uses a checkerboard of eight white and eight black squares; the average luminance of the white and black squares determines the contrast ratio. Since higher contrast ratios are associated with better picture quality, many consumers have learned to look for the display with the highest possible contrast ratio. Dynamic contrast ratio uses a technique that is found frequently in LCD TV’s. Do not make HDTV contrast ratio an essential purchasing factor. HDTV contrast ratio is a property of a display system, defined as the ratio of the luminance of the brightest color (white) to that of the darkest color (black) that the system is capable of producing. The rationale is based on a) adoption of the 3:1 contrast ratio for minimum acceptable contrast for normal observers, in the ANSI standard, and b) the empirical finding that in the population, visual acuity of 20/40 is associated with a contrast sensitivity loss of roughly 1%.
