  2. Contrast ratio - Wikipedia

    en.wikipedia.org/wiki/Contrast_ratio

    An LCD technology is dynamic contrast (DC), also called advanced contrast ratio (ACR), and smart contrast ratio (SCR [4]) and various other designations.When there is a need to display a dark image, a display that supports dynamic contrast underpowers the backlight lamp (or decreases the aperture of the projector's lens using an iris), but proportionately amplifies the transmission through the ...

  3. Display contrast - Wikipedia

    en.wikipedia.org/wiki/Display_contrast

    This ratio, often called contrast ratio, CR, (actually being a luminance ratio), is often used for high luminances and for specification of the contrast of electronic visual display devices. The luminance contrast (ratio), CR, is a dimensionless number , often indicated by adding ":1" to the value of the quotient (e.g. CR = 900:1).

  4. List of computer display standards - Wikipedia

    en.wikipedia.org/wiki/List_of_computer_display...

    A widely used de facto standard, introduced with XGA-2 and other early "multiscan" graphics cards and monitors, with an unusual aspect ratio of 5:4 (1.25:1) instead of the more common 4:3 (1. 3:1), meaning that even 4:3 pictures and video will appear letterboxed on the narrower 5:4 screens. This is generally the native resolution—with ...

  5. Comparison of CRT, LCD, plasma, and OLED displays - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_CRT,_LCD...

    Static contrast ratio Finite or infinite [citation needed] 150 to 8,100:1 [citation needed] Typically 1,000:1 - 3,000:1, Some models measured up to 20,333:1 [citation needed] "Between 0.0001 and 0.00001 nits" "Sony claims an OLED contrast range of 1,000,000:1." [1] Peak luminosity

  6. List of common display resolutions - Wikipedia

    en.wikipedia.org/wiki/List_of_common_display...

    This chart shows the most common display resolutions, with the color of each resolution type indicating the display ratio (e.g., red indicates a 4:3 ratio). This article lists computer monitor, television, digital film, and other graphics display resolutions that are in common use. Most of them use certain preferred numbers.

  7. High dynamic range - Wikipedia

    en.wikipedia.org/wiki/High_dynamic_range

    [23] [24] The HDR display must have either a peak brightness of over 1000 cd/m 2 and a black level less than 0.05 cd/m 2 (a contrast ratio of at least 20,000:1) or a peak brightness of over 540 cd/m 2 and a black level less than 0.0005 cd/m 2 (a contrast ratio of at least 1,080,000:1).

  8. Contrast (vision) - Wikipedia

    en.wikipedia.org/wiki/Contrast_(vision)

    The maximum contrast of an image is termed the contrast ratio or dynamic range. In images where the contrast ratio approaches the maximum possible for the medium, there is a conservation of contrast. In such cases, increasing contrast in certain parts of the image will necessarily result in a decrease in contrast elsewhere.

  9. Digital Fine Contrast - Wikipedia

    en.wikipedia.org/wiki/Digital_Fine_Contrast

    Digital Fine Contrast is a contrast-enhancing display technology introduced in 2006 by LG Display.It is used in the company's "Flatron" line of TFT monitors and implements a 'smart function' whereby it dynamically detects the characteristics of each frame to be displayed and automatically adjusts its contrast to obtain a sharper and more vivid image.
