Phosphor Burn-in
Screen burn-in, image burn-in, or ghost image, is a permanent discoloration of areas on an electronic display such as a cathode ray tube (CRT) in an old computer monitor or television set. It is caused by cumulative non-uniform use of the screen. Newer liquid-crystal displays (LCDs) may suffer from a phenomenon called image persistence instead, which is not permanent. One way to combat screen burn-in was the use of screensavers, which would move an image around to ensure that no one area of the screen remained illuminated for too long. Causes With phosphor-based electronic displays (for example CRT-type computer monitors, oscilloscope screens or plasma displays), non-uniform use of specific areas, such as prolonged display of non-moving images (text or graphics), repetitive contents in gaming graphics, or certain broadcasts with tickers and flags, can create a permanent ghost-like image of these objects or otherwise degrade image quality. This is because the phosphor compo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sign-on And Sign-off
A sign-on (or start-up in Commonwealth countries except Canada) is the beginning of operations for a radio or television station, generally at the start of each day. It is the opposite of a sign-off (or closedown in Commonwealth countries except Canada), which is the sequence of operations involved when a radio or television station shuts down its transmitters and goes off the air for a predetermined period; generally, this occurs during the overnight hours although a broadcaster's digital specialty or sub-channels may sign-on and sign-off at significantly different times as its main channels. Like other television programming, sign-on and sign-off sequences can be initiated by a broadcast automation system, and automatic transmission systems can turn the carrier signal and transmitter on/off by remote control. Sign-on and sign-off sequences have become less common due to the increasing prevalence of 24-hour-a-day, seven-day-a-week broadcasting. However, some national broadca ...

Indian-head Test Pattern
The Indian-head test pattern is a test card created by RCA of Harrison, New Jersey, which became the standard image of the RCA TK-1 monoscope. It features a drawing of a Native American wearing a headdress and numerous graphic elements designed to test different aspects of broadcast display. The card was introduced in 1939 and over the course of the black-and-white television broadcasting era was widely adopted by television stations across North America. As television broadcasting ritual The Indian-head test pattern became familiar to the large baby boom TV audiences in America from 1947 onwards; it would often follow the formal television station sign-off after the United States national anthem. The Indian head was also used by the Canadian Broadcasting Corporation (CBC) in Canada in conjunction with its own monochrome test pattern, following the Canadian national anthem sign-off in the evening, and during its final years in the late-1970s and early-1980s it was shown bef ...

Android (operating System)
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008. Most versions of Android are proprietary. The core components are taken from the Android Open Source Project (AOSP), which is free and open-source software (FOSS) primarily licensed under the Apache License. When Android is installed on devices, the ability to modify the otherwise free and open-source software is usually restricted, either by not providing the corresponding source code or by preventing reinstallation through technical measures, thus rendering the installed version proprietary. Most Android devices ship with additional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pixel Shifting
Pixel shifting refers to various technical methods, either to diminish damage to displays by preventing "burn in" of static images or to enhance resolution of displays, projectors, and digital imaging devices. The term is often used synonymously with the more specific term pixel shift. Purposes Avoid burn-in See Pixel shifting avoids burn-in explained in detail for both analogue and digital screens. Enhance character display resolution on terminals Computer terminals such as the HP 2645A used a half-shift algorithm to move pixel positions by half a screen pixel in order to support the generation of multiple complex character sets. Increase projection resolution Pixel shifting has been implemented in video projectors to expand the native 1080p resolution to produce an effectively 4K image on the screen. An exemplary implementation by the electronics corporation JVC is referred to as "e-shift". Increase capture and/or tonal resolution Pixel shifting by movement of ...

Parallax Scrolling
Parallax scrolling is a technique in computer graphics where background images move past the camera more slowly than foreground images, creating an illusion of depth in a 2D scene of distance. The technique grew out of the multiplane camera technique used in traditional animation since the 1930s. Parallax scrolling was popularized in 2D computer graphics with its introduction to video games in the early 1980s. Some parallax scrolling was used in the arcade video game ''Jump Bug'' (1981). It used a limited form of parallax scrolling with the main scene scrolling while the starry night sky is fixed and clouds move slowly, adding depth to the scenery. The following year, ''Moon Patrol'' (1982) implemented a full form of parallax scrolling, with three separate background layers scrolling at different speeds, simulating the distance between them. ''Moon Patrol'' is often credited with popularizing parallax scrolling. '' Jungle King'' (1982), later called ''Jungle Hunt'', also had par ...

IPhone X
The iPhone X (Roman numeral "X" pronounced "ten", also known as iPhone 10) is a smartphone designed, developed and marketed by Apple Inc. It is part of the 11th generation of the iPhone. Available for pre-order from October 27, 2017, it was released on November 3, 2017. The naming of the iPhone X (skipping the iPhone 9) is to mark the 10th anniversary of the iPhone. The iPhone X used a glass and stainless-steel form factor and " bezel-less" design, shrinking the bezels while not having a "chin", unlike many Android phones. It was the first iPhone to use an OLED screen. The home button's fingerprint sensor was replaced with a new type of authentication called Face ID, which used sensors to scan the user's face to unlock the device. This face-recognition capability also enabled emojis to be animated following the user's expression (Animoji). With a bezel-less design, iPhone user interaction changed significantly, using gestures to navigate the operating system rather than the ho ...
