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

    For the majority of images it will consume 60–80% of the power of an LCD. OLED displays use 40% of the power of an LCD displaying an image that is primarily black as they lack the need for a backlight, [ 39] while OLED can use more than three times as much power to display a mostly white image compared to an LCD. [ 40]

  4. 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).

    en.wikipedia.org/wiki/Large-screen_television...

    Static contrast ratio is measured on a static image at some instant in time. Dynamic contrast ratio is measured on the image over a period of time. Manufacturers can market either static or dynamic contrast ratio depending on which one is higher. Aspect ratio: The ratio of the display width to the display height. The aspect ratio of a ...

  6. High-dynamic-range television - Wikipedia

    en.wikipedia.org/wiki/High-dynamic-range_television

    High-dynamic-range television ( HDR-TV) is a technology that uses high dynamic range (HDR) to improve the quality of display signals. It is contrasted with the retroactively-named standard dynamic range (SDR). HDR changes the way the luminance and colors of videos and images are represented in the signal, and allows brighter and more detailed ...

  7. High dynamic range - Wikipedia

    en.wikipedia.org/wiki/High_dynamic_range

    High dynamic range ( HDR ), also known as wide dynamic range, extended dynamic range, or expanded dynamic range, is a signal with a higher dynamic range than usual. The term is often used in discussing the dynamic ranges of images, videos, audio or radio. It may also apply to the means of recording, processing, and reproducing such signals ...

  8. 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.

  9. Liquid-crystal display - Wikipedia

    en.wikipedia.org/wiki/Liquid-crystal_display

    A liquid-crystal display ( LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly [ 1] but instead use a backlight or reflector to produce images in color or monochrome.
