Some LCD monitors using this technology have a feature called " Dynamic Contrast " where the backlight is dimmed to the brightest color that appears on the screen, allowing the 1000: 1 contrast ratio of the LCD panel to be scaled to different light intensities, resulting in the " 30000: 1 " contrast ratios seen in the advertising on some of these monitors.

* Brightness and contrast ratio: Contrast ratio is the ratio of the brightness of a full-on pixel to a full-off pixel and, as such, would be directly tied to brightness if not for the invention of the blinking backlight ( or burst dimming ).

* Contrast ratio, a measure of a display system

Contrast ratio is also improved over image intensifiers: flat-panel detectors are linear over a very wide latitude, whereas image intensifiers have a maximum contrast ratio of about 35: 1.

There is no official, standardized way to measure contrast ratio for a system or its parts, nor is there a standard for defining " Contrast Ratio " that is accepted by any standards organization so ratings provided by different manufacturers of display devices are not necessarily comparable to each other due to differences in method of measurement, operation, and unstated variables.

* Contrast: it describes the ratio between the thickest and narrowest points on the letter ' O.

Some increase in dynamic range in LCD monitors can be achieved by automatically reducing the backlight for dark scenes ( LG calls it Digital Fine Contrast, Samsung are quoting " dynamic contrast ratio "), or having an array of brighter and darker LED backlights ( BrightSide Technologies – now part of Dolby, and Samsung in development ).

This palette is nearly always justified with the specious argument that paints are " impure " carriers of " primary color ", a misunderstanding of subtractive color mixture that appears in Michel-Eugene Chevreul's " Simultaneous Color Harmony and Contrast " published in 1839.

In 1813 Chevreul was appointed professor of chemistry at the Lycée Charlemagne, and subsequently undertook the directorship of the Gobelins tapestry works, where he carried out his researches on colour contrasts ( De la loi du contraste simultané des couleurs, 1839 ; the 1854 English translation is titled The Principles of Harmony and Contrast of Colors ).

Contrast, saturation, color and brightness can also be adjusted in opposite frames to increase picture quality in the final playback video file.

These ideas and many personal color observations were summarized in two founding documents in color theory: the Theory of Colors ( 1810 ) by the German poet and government minister Johann Wolfgang von Goethe, and The Law of Simultaneous Color Contrast ( 1839 ) by the French industrial chemist Michel-Eugène Chevreul.

Contrast effects shape not only visual qualities like color and brightness, but other kinds of perception, including the perception of weight.
