  2. Screen burn-in - Wikipedia

    en.wikipedia.org/wiki/Screen_burn-in

    Screen burn-in, image burn-in, ghost image, or shadow image, is a permanent discoloration of areas on an electronic visual display such as a cathode-ray tube (CRT) in an older computer monitor or television set. It is caused by cumulative non-uniform use of the screen. Newer liquid-crystal displays (LCDs) may suffer from a phenomenon called ...

  3. Image persistence - Wikipedia

    en.wikipedia.org/wiki/Image_persistence

    Image persistence, or image retention, is the LCD and plasma display equivalent of screen burn-in. Unlike screen burn, the effects are usually temporary and often not visible without close inspection. Plasma displays experiencing severe image persistence can result in screen burn-in instead. Image persistence can occur as easily as having ...

  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. Screensaver - Wikipedia

    en.wikipedia.org/wiki/Screensaver

    Screensaver. Einstein@Home interactive screensaver. A screensaver (or screen saver) is a computer program that blanks the display screen or fills it with moving images or patterns when the computer has been idle for a designated time. The original purpose of screensavers was to prevent phosphor burn-in on CRT or plasma computer monitors (hence ...

  6. Plasma display - Wikipedia

    en.wikipedia.org/wiki/Plasma_display

    In 2006, LCD prices started to fall rapidly and their screen sizes increased, although plasma televisions maintained a slight edge in picture quality and a price advantage for sets at the critical 42" size and larger. By late 2006, several vendors were offering 42" LCDs, albeit at a premium price, encroaching upon plasma's only stronghold.

  7. 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, [40] while OLED can use more than three times as much power to display a mostly white image compared to an LCD. [41]

  8. IPS panel - Wikipedia

    en.wikipedia.org/wiki/IPS_panel

    IPS panel. IPS (in-plane switching) is a screen technology for liquid-crystal displays (LCDs). In IPS, a layer of liquid crystals is sandwiched between two glass surfaces. The liquid crystal molecules are aligned parallel to those surfaces in predetermined directions (in-plane). The molecules are reoriented by an applied electric field, while ...

  9. Defective pixel - Wikipedia

    en.wikipedia.org/wiki/Defective_pixel

    A defective pixel is a pixel on a liquid crystal display (LCD) that is not functioning properly. The ISO standard ISO 13406-2 distinguishes between three different types of defective pixels, [1] while hardware companies tend to have further distinguishing types. [2] Similar defects can also occur in charge-coupled device (CCD) and CMOS image ...
