  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. Liquid crystal - Wikipedia

    en.wikipedia.org/wiki/Liquid_crystal

    Liquid crystal ( LC) is a state of matter whose properties are between those of conventional liquids and those of solid crystals. For example, a liquid crystal can flow like a liquid, but its molecules may be oriented in a common direction as in a solid. There are many types of LC phases, which can be distinguished by their optical properties ...

  4. 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.

  5. Response time compensation - Wikipedia

    en.wikipedia.org/wiki/Response_Time_Compensation

    Response time compensation for liquid-crystal displays is also known as "Overdrive". LCDs moderate light flow by rotating liquid crystal molecules to various alignments where they transmit more or less light depending on the electrical setting at each individual pixel . The speed at which these liquid crystal molecules rotate is relatively slow ...

  6. Response surface methodology - Wikipedia

    en.wikipedia.org/wiki/Response_surface_methodology

    In statistics, response surface methodology ( RSM) explores the relationships between several explanatory variables and one or more response variables. RSM is an empirical model which employs the use of mathematical and statistical techniques to relate input variables, otherwise known as factors, to the response.

  7. Thermographic camera - Wikipedia

    en.wikipedia.org/wiki/Thermographic_camera

    A thermographic camera (also called an infrared camera or thermal imaging camera, thermal camera or thermal imager) is a device that creates an image using infrared (IR) radiation, similar to a normal camera that forms an image using visible light. Instead of the 400–700 nanometre (nm) range of the visible light camera, infrared cameras are ...

  8. Mental chronometry - Wikipedia

    en.wikipedia.org/wiki/Mental_chronometry

    Mental chronometry is the scientific study of processing speed or reaction time on cognitive tasks to infer the content, duration, and temporal sequencing of mental operations. Reaction time (RT; also referred to as " response time ") is measured by the elapsed time between stimulus onset and an individual's response on elementary cognitive ...

  9. Delayed-choice quantum eraser - Wikipedia

    en.wikipedia.org/wiki/Delayed-choice_quantum_eraser

    A delayed-choice quantum eraser experiment, first performed by Yoon-Ho Kim, R. Yu, S. P. Kulik, Y. H. Shih and Marlan O. Scully, [1] and reported in early 1998, is an elaboration on the quantum eraser experiment that incorporates concepts considered in John Archibald Wheeler 's delayed-choice experiment.
