  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 to display information. Liquid crystals do not emit light directly [1] but instead use a backlight or reflector to produce images in color or monochrome. [2]

  3. LCD classification - Wikipedia

    en.wikipedia.org/wiki/LCD_classification

    Liquid crystals can be aligned by both magnetic and electric fields. The strength of the required magnetic field is too high to be feasible for display applications. One electro-optical effect with LCs requires a current through the LC-cell; all other practiced electro-optical effects only require an electric field (without current) for ...

  4. Liquid crystal on silicon - Wikipedia

    en.wikipedia.org/wiki/Liquid_crystal_on_silicon

    The liquid crystal layer controls the polarization of light that passes through it, while the reflective layer reflects the light back towards the optical system. The silicon substrate is used to control the individual pixels and provides the necessary electronics to drive the LCos panel.

  5. Liquid crystal - Wikipedia

    en.wikipedia.org/wiki/Liquid_crystal

    Liquid crystals find wide use in liquid crystal displays, which rely on the optical properties of certain liquid crystalline substances in the presence or absence of an electric field. In a typical device, a liquid crystal layer (typically 4 μm thick) sits between two polarizers that are crossed (oriented at 90° to one another).

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

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

    Display lag is extremely low due to its nature, which does not have the ability to store image data before output, unlike LCDs, plasma displays and OLED displays. [56] Extremely bulky and heavy construction in comparison to other display technologies. Large displays would be unsuitable for wall mounting. New models are no longer produced.

  7. Transflective liquid-crystal display - Wikipedia

    en.wikipedia.org/wiki/Transflective_liquid...

    A transflective liquid-crystal display [1] is a liquid-crystal display (LCD) with an optical layer that reflects and transmits light (transflective is a portmanteau of transmissive and reflective). [2] Under bright illumination (e.g. when exposed to daylight) the display acts mainly as a reflective display with the contrast being constant with ...

  8. Blue phase mode LCD - Wikipedia

    en.wikipedia.org/wiki/Blue_Phase_Mode_LCD

    A blue phase mode LCD is a liquid crystal display (LCD) technology that uses highly twisted cholesteric phases in a blue phase.It was first proposed in 2007 to obtain a better display of moving images with, for example, frame rates of 100–120 Hz to improve the temporal response of LCDs. [1]

  9. Cholesteric liquid crystal - Wikipedia

    en.wikipedia.org/wiki/Cholesteric_liquid_crystal

    A cholesteric liquid-crystal display (ChLCD) is a display containing a liquid crystal with a helical structure and which is therefore chiral. Cholesteric liquid crystals are also known as chiral nematic liquid crystals. They organize in layers with no positional ordering within layers, but a director axis which varies with layers.
