Canon's 36" prototype SED, shown at the 2006 CES Another view of the same display, showing what was a thin case at the time. A surface-conduction electron-emitter display (SED) is a display technology for flat panel displays developed by a number of companies. SEDs uses nanoscopic-scale electron emitters to energize colored phosphors and ...
A field-emission display (FED) is a flat panel display technology that uses large-area field electron emission sources to provide electrons that strike colored phosphor to produce a color image. In a general sense, an FED consists of a matrix of cathode-ray tubes , each tube producing a single sub-pixel, grouped in threes to form red-green-blue ...
An electron gun (also called electron emitter) is an electrical component in some vacuum tubes that produces a narrow, collimated electron beam that has a precise kinetic energy. The largest use is in cathode-ray tubes (CRTs), used in older television sets , computer displays and oscilloscopes , before the advent of flat-panel displays .
A vacuum fluorescent display (VFD) is a display device once commonly used on consumer electronics equipment such as video cassette recorders, car radios, and microwave ovens. A VFD operates on the principle of cathodoluminescence , roughly similar to a cathode-ray tube , but operating at much lower voltages.
The introduction of TN-effect displays led to their rapid expansion in the display field, quickly pushing out other common technologies like monolithic LEDs and CRTs for most electronics. By the 1990s, TN-effect LCDs were largely universal in portable electronics, although since then, many applications of LCDs adopted alternatives to the TN ...
Currently, the only display technology capable of multi-syncing (displaying different resolutions and refresh rates without the need for scaling). [50] 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. [ 51 ]
An electronic visual display is a display device that can display images, ... Surface-conduction electron-emitter display (SED) Research & manufacturing: Principle
A layer of quantum dots is sandwiched between layers of electron-transporting and hole-transporting materials. An applied electric field causes electrons and holes to move into the quantum dot layer and recombine forming an exciton that excites a QD. This scheme is commonly studied for quantum dot display. The tunability of emission wavelengths ...
