  2. 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. [57] 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. [58]

  3. 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.

  4. 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.

  5. Display lag - Wikipedia

    en.wikipedia.org/wiki/Display_lag

    This lag time has been measured as high as 68 ms, [1] or the equivalent of 3-4 frames on a 60 Hz display. Display lag is not to be confused with pixel response time, which is the amount of time it takes for a pixel to change from one brightness value to another. Currently the majority of manufacturers quote the pixel response time, but neglect ...

  6. Refresh rate - Wikipedia

    en.wikipedia.org/wiki/Refresh_rate

    Refresh rate. The refresh rate, also known as vertical refresh rate or vertical scan rate in reference to terminology originating with the cathode-ray tubes (CRTs), is the number of times per second that a raster-based display device displays a new image. This is independent from frame rate, which describes how many images are stored or ...

  7. Heartbeat (computing) - Wikipedia

    en.wikipedia.org/wiki/Heartbeat_(computing)

    Heartbeat (computing) In computer science, a heartbeat is a periodic signal generated by hardware or software to indicate normal operation or to synchronize other parts of a computer system. [ 1][ 2] Heartbeat mechanism is one of the common techniques in mission critical systems for providing high availability and fault tolerance of network ...

  8. Memory hierarchy - Wikipedia

    en.wikipedia.org/wiki/Memory_hierarchy

    In computer organisation, the memory hierarchy separates computer storage into a hierarchy based on response time. Since response time, complexity, and capacity are related, the levels may also be distinguished by their performance and controlling technologies. [ 1] Memory hierarchy affects performance in computer architectural design ...

  9. Computer monitor - Wikipedia

    en.wikipedia.org/wiki/Computer_monitor

    A computer monitor is an output device that displays information in pictorial or textual form. A discrete monitor comprises a visual display, support electronics, power supply, housing, electrical connectors, and external user controls. The display in modern monitors is typically an LCD with LED backlight, having by the 2010s replaced CCFL ...
