LCD Television
A liquid-crystal-display television (LCD TV) is a television set that uses a liquid-crystal display to produce images. It is by far the most widely produced and sold type of television display. LCD TVs are thin and light, but have some disadvantages compared to other display types such as high power consumption, poorer contrast ratio, and inferior color gamut. LCD TVs rose in popularity in the early years of the 21st century, and exceeded sales of cathode-ray-tube televisions worldwide from late 2007 on. Sales of CRT TVs dropped rapidly after that, as did sales of competing technologies such as plasma display panels and rear-projection television. History Early efforts Passive matrix LCDs first became common as portable computer displays in the 1980s, competing for market share with plasma displays. The LCDs had very slow refresh rates that blurred the screen even with scrolling text, but their light weight and low cost were major benefits. Screens using reflective LCDs r ...

Computer Monitor
A computer monitor is an output device that displays information in pictorial or textual form. A discrete monitor comprises a electronic visual display, visual display, support electronics, power supply, Housing (engineering), housing, electrical connectors, and external user controls. The display in modern monitors is typically an Liquid-crystal display, LCD with LED-backlit LCD, LED backlight, having by the 2010s replaced cold-cathode fluorescent lamp, CCFL Backlight, backlit LCDs. Before the mid-2000s, most monitors used a cathode-ray tube, cathode-ray tube (CRT) as the image output technology. A monitor is typically connected to its host computer via DisplayPort, HDMI, USB-C, Digital Visual Interface, DVI, or VGA connector, VGA. Monitors sometimes use other proprietary connectors and signals to connect to a computer, which is less common. Originally computer monitors were used for data processing while television sets were used for video. From the 1980s onward, computers ( ...

Surface-conduction Electron-emitter Display
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 produce an image. In a general sense, a SED consists of a matrix of tiny cathode-ray tubes, each "tube" forming a single sub-pixel on the screen, grouped in threes to form red-green-blue (RGB) pixels. SEDs combine the advantages of CRTs, namely their high contrast ratios, wide viewing angles, and very fast response times, with the packaging advantages of LCD and other flat panel displays. After considerable time and effort in the early and mid-2000s, SED efforts started winding down in 2009 as LCD became the dominant technology. In August 2010, Canon announced they were shutting down their joint effort to develop SEDs commercially, signaling the end of development efforts. SEDs were closely related to another developing display technology, the field-emission dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Field-emission Display
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 (RGB) pixels. FEDs combine the advantages of CRTs, namely their high contrast levels and very fast response times, with the packaging advantages of LCD and other flat-panel technologies. They also offer the possibility of requiring less power, about half that of an LCD system. FEDs can also be made transparent. Sony was the major proponent of the FED design and put considerable research and development effort into the system during the 2000s, planning mass production in 2009. Sony's FED efforts started winding down in 2009, as LCD became the dominant flat-panel technology. In January 2010, AU Optronics announced that it acquired essential ...

MicroLED
MicroLED, also known as micro-LED, mLED or μLED is an emerging flat-panel display technology consisting of arrays of microscopic Light-emitting diode, LEDs forming the individual pixel elements. Inorganic semiconductor microLED (μLED) technology was first invented in 2000 by the research group of Hongxing Jiang and Jingyu Lin of Texas Tech University (TTU) while they were at Kansas State University, Kansas State University (KSU). The first high-resolution and video-capable InGaN microLED microdisplay in VGA format was realized in 2009 by Jiang, Lin and their colleagues at Texas Tech University and III-N Technology, Inc. via active driving of a microLED array by a complementary metal-oxide semiconductor (CMOS) IC. Compared to LED-backlit LCD, conventional LCD displays, microLED displays offer greatly reduced energy requirements while also offering pixel-level light control and a high contrast ratio. Compared to OLED, OLEDs, the inorganic nature of microLEDs gives them a longer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OLED
An organic light-emitting diode (OLED), also known as organic electroluminescent (organic EL) diode, is a type of light-emitting diode (LED) in which the emissive electroluminescent layer is an organic compound film that emits light in response to an electric current. This organic layer is situated between two electrodes; typically, at least one of these electrodes is transparent. OLEDs are used to create digital displays in devices such as television screens, computer monitors, and portable systems such as smartphones and handheld game consoles. A major area of research is the development of white OLED devices for use in solid-state lighting applications. There are two main families of OLED: those based on small molecules and those employing polymers. Adding mobile ions to an OLED creates a light-emitting electrochemical cell (LEC) which has a slightly different mode of operation. An OLED display can be driven with a passive-matrix (PMOLED) or active-matrix ( AMOLED) c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Consumer Electronics Show
CES (; formerly an initialism for Consumer Electronics Show) is an annual trade show organized by the Consumer Technology Association (CTA). Held in January at the Las Vegas Convention Center in Winchester, Nevada, United States, the event typically hosts presentations of new products and technologies in the consumer electronics industry. History The first CES was held in June 1967 in New York City. It was a spin-off of the Chicago Music Show which, until then, had served as the main event for exhibiting consumer electronics. The event had 17,500 attendees and over 100 exhibitors; the kickoff speaker was Motorola chairman Bob Galvin. From 1978 to 1994, CES was held twice each year: once in January in Las Vegas as the ''Winter Consumer Electronics Show'' (WCES) and once in June in Chicago as the ''Summer Consumer Electronics Show'' (SCES). The winter show was held in Las Vegas in 1995 as planned. However, since the summer Chicago shows were beginning to lose popularity, the ...

Economics Of Christmas
The economics of Christmas are significant because Christmas is typically a high-volume selling season for goods suppliers around the world. Sales increase dramatically as people purchase gifts, decorations, and supplies to celebrate. In the U.S., the "Christmas shopping season" starts as early as October. In Canada, merchants begin advertising campaigns just before Halloween (31 October), and step up their marketing following Remembrance Day on 11 November. In the UK and Ireland, the Christmas shopping season starts from mid-November, around the time when high street Christmas lights are turned on.Julia Kollewe Monday (29 November 2010West End spree worth £250m marks start of Christmas shopping season''The Guardian'' In the United States, it has been calculated that about one fifth of retail sales to one quarter of all personal spending takes place during the Christmas/holiday shopping season.

720p
720p (720 lines progressive) is a progressive HD signal format with 720 horizontal lines/1280 columns and an aspect ratio (AR) of 16:9, normally known as widescreen HD (1.78:1). All major HD broadcasting standards (such as SMPTE 292M) include a 720p format, which has a resolution of 1280×720. The number ''720'' stands for the 720 horizontal scan lines of image display resolution (also known as 720 pixels of vertical resolution). The ''p'' stands for progressive scan, i.e. non-interlaced. When broadcast at 60 frames per second, 720p features the highest temporal resolution possible under the ATSC and DVB standards. The term assumes a widescreen aspect ratio of 16:9, thus implying a resolution of 1280×720 px (0.9 megapixels). 720i (720 lines interlaced) is an erroneous term found in numerous sources and publications. Typically, it is a typographical error in which the author is referring to the 720p HDTV format. However, in some cases it is incorrectly presented ...

1080p
1080p (1920 × 1080 progressively displayed pixels; also known as Full HD or FHD, and BT.709) is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; the ''p'' stands for progressive scan, ''i.e.'' non- interlaced. The term usually assumes a widescreen aspect ratio of 16:9, implying a resolution of 2.1 megapixels. It is often marketed as Full HD or FHD, to contrast 1080p with 720p resolution screens. Although 1080p is sometimes referred to as 2K resolution (meaning having a horizontal resolution of approximately 2,000 pixels), other sources differentiate between 1080p and (true) 2K resolution. 1080p video signals are supported by ATSC standards in the United States and DVB standards in Europe. Applications of the 1080p standard include television broadcasts, Blu-ray Discs, smartphones, Internet content such as YouTube videos and Netflix TV shows and movi ...
