Electronic visual displayDisplay device for presentation of images, video, or text transmitted electronically An electronic visual display is a display device that can display images, video, or text that is transmitted electronically. Electronic visual displays include television sets, computer monitors, and digital signage. They are ubiquitous in mobile computing applications like tablet computers, smartphones, and information appliances.
Quantum dot displayA quantum dot display is a display device that uses quantum dots (QDs), semiconductor nanocrystals which can produce pure monochromatic red, green, and blue light. QDs are either photo-emissive (photoluminescent) or electro-emissive (electroluminescent) allowing them to be readily incorporated into new emissive display architectures.
Liquid-crystal displayA 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 but instead use a backlight or reflector to produce images in color or monochrome.
AMOLEDActive-matrix organic light-emitting diode (AMOLED) screens are a type of OLED display device technology. OLED describes a specific type of thin-film-display technology in which organic compounds form the electroluminescent material, and active matrix refers to the technology behind the addressing of pixels. Since 2010, AMOLED displays have been used in mobile phones, media players, TVs, and digital cameras.
Computer monitorA 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 CCFLbacklit LCDs. Before the mid-2000s, most monitors used a cathode ray tube (CRT) as the image output technology.
Television setA television set or television receiver (more commonly called TV, TV set, television, telly, or tele) is an electronic device for viewing and hearing television broadcasts. It combines a tuner, display, and loudspeakers. Introduced in the late 1920s in mechanical form, television sets became a popular consumer product after World War II in electronic form, using cathode ray tube (CRT) technology.
Output deviceAn output device is any piece of computer hardware that converts information or data into a human-perceptible form or, historically, into a physical machine-readable form for use with other non-computerized equipment. It can be text, graphics, tactile, audio, or video. Examples include monitors, printers and sound cards.
Refreshable braille displayA refreshable braille display or braille terminal is an electro-mechanical device for displaying braille characters, usually by means of round-tipped pins raised through holes in a flat surface. Visually impaired computer users who cannot use a standard computer monitor can use it to read text output. Deafblind computer users may also use refreshable braille displays.
InformationInformation is an abstract concept that refers to something which has the power to inform. At the most fundamental level, it pertains to the interpretation (perhaps formally) of that which may be sensed, or their abstractions. Any natural process that is not completely random and any observable pattern in any medium can be said to convey some amount of information.
Visual systemThe visual system is the physiological basis of visual perception (the ability to detect and processlight). The system detects, transduces and interprets information concerning light within the visible range to construct an image and build a mental model of the surrounding environment. The visual system is associated with the eye and functionally divided into the optical system (including cornea and lens) and the neural system (including the retina and visual cortex).
SignalA signal is both the process and the result of transmission of data over some media accomplished by embedding some variation. Signals are important in multiple subject fields, including signal processing, information theory and biology. In signal processing, a signal is a function that conveys information about a phenomenon. Any quantity that can vary over space or time can be used as a signal to share messages between observers.
Somatosensory systemNerve system for sensing touch, temperature, body position, and pain Touch is a crucial means of receiving information. This photo shows tactile markings identifying stairs for visually impaired people. The somatosensory system, or somatic sensory system, is a subset of the sensory nervous system.*As an Amazon Associate I earn from qualifying purchases.
