  2. 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.

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

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

    The LCD grid can mask effects of spatial and grayscale quantization, creating the illusion of higher image quality. Is the cheapest display technology currently produced, with some entry-level models selling for less than $100. Screen-door effects are more noticeable than LCD when up close, or on larger sizes.

  4. Twisted nematic field effect - Wikipedia

    en.wikipedia.org/wiki/Twisted_nematic_field_effect

    The twisted nematic effect ( TN-effect) was a major technological breakthrough that made the manufacture of large, thin liquid crystal displays practical and cost competitive. Unlike earlier flat-panel displays, TN-cells did not require a current to flow for operation and used low operating voltages suitable for use with batteries.

  5. Response time (technology) - Wikipedia

    en.wikipedia.org/wiki/Response_time_(technology)

    Response time is the amount of time a pixel in a display takes to change. It is measured in milliseconds (ms). Lower numbers mean faster transitions and therefore fewer visible image artifacts. Display monitors with long response times would create display motion blur around moving objects, making them unacceptable for rapidly moving images.

  6. Pollaczek–Khinchine formula - Wikipedia

    en.wikipedia.org/wiki/Pollaczek–Khinchine_formula

    Contents. Pollaczek–Khinchine formula. In queueing theory, a discipline within the mathematical theory of probability, the Pollaczek–Khinchine formula states a relationship between the queue length and service time distribution Laplace transforms for an M/G/1 queue (where jobs arrive according to a Poisson process and have general service ...

  7. Temporal resolution - Wikipedia

    en.wikipedia.org/wiki/Temporal_resolution

    The temporal resolution is a resolution somewhat the 'time' dual to the 'space' resolution of an image. In a similar way, the sample rate is equivalent to the pixel pitch on a display screen, whereas the optical resolution of a display screen is equivalent to temporal uncertainty. Note that both this form of image space and time resolutions are ...

  8. Microsoft Excel - Wikipedia

    en.wikipedia.org/wiki/Microsoft_Excel

    Microsoft Excel is a spreadsheet editor developed by Microsoft for Windows, macOS, Android, iOS and iPadOS. It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA). Excel forms part of the Microsoft 365 suite of software.

  9. Lowest common denominator - Wikipedia

    en.wikipedia.org/wiki/Lowest_common_denominator

    Description. The lowest common denominator of a set of fractions is the lowest number that is a multiple of all the denominators: their lowest common multiple. The product of the denominators is always a common denominator, as in: but it is not always the lowest common denominator, as in: Here, 36 is the least common multiple of 12 and 18.
