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.
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 tasks (ECTs), which are relatively simple perceptual ...
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 ...
Wheeler's delayed-choice experiment describes a family of thought experiments in quantum physics proposed by John Archibald Wheeler, with the most prominent among them appearing in 1978 and 1984. [1] These experiments are attempts to decide whether light somehow "senses" the experimental apparatus in the double-slit experiment it travels through, adjusting its behavior to fit by assuming an ...
A cathode-ray tube(CRT) is a vacuum tubecontaining one or more electron guns, which emit electronbeams that are manipulated to display images on a phosphorescentscreen.[2] The images may represent electrical waveformson an oscilloscope, a frameof videoon an analogtelevision set(TV), digitalraster graphicson a computer monitor, or other phenomena like radartargets. A CRT in a TV is commonly ...
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.
Stroop effect. Naming the displayed color of a printed word is an easier and quicker task if the word matches the color (top) than if it does not (bottom). In psychology, the Stroop effect is the delay in reaction time between congruent and incongruent stimuli. The effect has been used to create a psychological test (the Stroop test) that is ...
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 .
