IPad (1st Generation)
The first-generation iPad ( ) (retrospectively referred to unofficially as the iPad 1, or original iPad) is a tablet computer designed and marketed by Apple Inc. as the first device in the iPad lineup of tablet computers. The device features an Apple A4 SoC, a 9.7" touchscreen display, and, on certain variants, the capability of accessing cellular networks. Using the iOS operating system, the iPad can play music, send and receive email and browse the web. Other functions, which include the ability to play games and access references, GPS navigation software and social network services can be enabled by downloading apps. The device was announced and unveiled on January 27, 2010, by Steve Jobs at an Apple press event. On April 3, 2010, the Wi-Fi variant of the device was released in the USA, followed by the release of the " Wi-Fi + 3G" variant on April 30. On May 28, 2010, it was released in Australia, Canada, France, Japan, Italy, Germany, Spain, Switzerland a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IOS 11
iOS 11 is the eleventh major release of the iOS mobile operating system developed by Apple Inc., being the successor to iOS 10. It was announced at the company's Worldwide Developers Conference on June 5, 2017, and released on September 19, 2017. It was succeeded by iOS 12 on September 17, 2018. Changes iOS 11 brought many changes to iOS. Some major highlights were: * The lock screen and Notification Center were combined, allowing all notifications to be displayed directly on the lock screen. * The control center was completely redesigned, combining all pages into a single unified page. It also brought the ability to rearrange the position of the controls, some of which could be used with 3D Touch for quick access to additional options. * The App Store received its first major design overhaul since iOS 7 to focus on editorial content and daily highlights. * A " Files" file manager app allowed access to files stored locally on-device and in iCloud and other cloud services.

DCI-P3
P3 is an RGB color space. DCI-P3 (Digital Cinema Initiative) is used with digital theatrical motion picture distribution (DCDM). Display P3 is a variant developed by Apple Inc. for wide-gamut displays. __TOC__ History Development of the standard In 2005, Digital Cinema Initiatives, LCC in Hollywood, California released the ''Digital Cinema System Specification version 1.0'', which defined the colorimetry of what would become known as the DCI-P3 color space. According to section 8.3.4 in the specification, the blue primary color is the same as Rec. 709, sRGB, and Adobe RGB, with a dominant wavelength of 464.2 nm. The red primary is a slightly deeper red than sRGB and Adobe RGB, with a dominant wavelength of 614.9 nm. The most significant difference is the green primary which is much closer to the spectral locus than either sRGB or Adobe RGB. DCI-P3's green primary has a dominant wavelength of 544.2 nm. Adobe RGB's green primary is more blueish with a do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SRGB
sRGB is a standard RGB (red, green, blue) color space that HP and Microsoft created cooperatively in 1996 to use on monitors, printers, and the World Wide Web. It was subsequently standardized by the International Electrotechnical Commission (IEC) as IEC 61966-2-1:1999. sRGB is the current defined standard colorspace for the web, and it is usually the assumed colorspace for images that are neither tagged for a colorspace nor have an embedded color profile. sRGB essentially codifies the display specifications for the computer monitors in use at that time, which greatly aided its acceptance. sRGB uses the same color primaries and white point as ITU-R BT.709 standard for HDTV, a transfer function (or gamma) compatible with the era's CRT displays, and a viewing environment designed to match typical home and office viewing conditions. An amendment of the IEC 61966-2-1 standard document that defines sRGB includes the definition of a number of variants including sYCC, which i ...

Lipophobicity
Lipophobicity, also sometimes called lipophobia (from the Greek λιποφοβία from λίπος ''lipos'' "fat" and φόβος ''phobos'' "fear"), is a chemical property of chemical compounds which means " fat rejection", literally "fear of fat". Lipophobic compounds are those not soluble in lipids or other non-polar solvents. From the other point of view, they do not absorb fats. "Oleophobic" (from the Latin ''oleum'' "oil", Greek ελαιοφοβικό ''eleophobico'' from έλαιο ''eleo'' "oil" and φόβος ''phobos'' "fear") refers to the physical property of a molecule that is seemingly repelled from oil. (Strictly speaking, there is no repulsive force involved; it is an absence of attraction.) The most common lipophobic substance is water. Fluorocarbons are also lipophobic/oleophobic in addition to being hydrophobic. Uses A lipophobic coating has been used on the touchscreens of Apple's iPhones since the 3GS, their iPads, Nokia's N9 and Lumia devices, the HTC ...

Aspect Ratio (image)
The aspect ratio of an image is the ratio of its width to its height, and is expressed with two numbers separated by a colon, such as ''16:9'', sixteen-to-nine. For the ''x'':''y'' aspect ratio, the image is ''x'' units wide and ''y'' units high. Common aspect ratios are 1.85:1 and 2.39:1 in cinematography, 4:3 and 16:9 in television photography, and 3:2 in still photography. Some common examples The common film aspect ratios used in cinemas are 1.85:1 and 2.39:1.The 2.39:1 ratio is commonly labeled 2.40:1, e.g., in the American Society of Cinematographers' ''American Cinematographer Manual'' (Many widescreen films before the 1970 SMPTE revision used 2.35:1). Two common videographic aspect ratios are 4:3 (1.:1), the universal video format of the 20th century, and 16:9 (1.:1), universal for high-definition television and European digital television. Other cinema and video aspect ratios exist, but are used infrequently. In still camera photography, the most common aspec ...

IPS Panel
IPS (in-plane switching) is a screen technology for liquid-crystal displays (LCDs). In IPS, a layer of liquid crystals is sandwiched between two glass surfaces. The liquid crystal molecules are aligned parallel to those surfaces in predetermined directions (''in-plane''). The molecules are reoriented by an applied electric field, whilst remaining essentially parallel to the surfaces to produce an image. It was designed to solve the strong viewing angle dependence and low-quality color reproduction of the twisted nematic field effect (TN) matrix LCDs prevalent in the late 1980s. History The TN method was the only viable technology for active matrix TFT LCDs in the late 1980s and early 1990s. Early panels showed grayscale inversion from up to down, and had a high response time (for this kind of transition, 1 ms is visually better than 5 ms). In the mid-1990s new technologies were developed—typically IPS and Vertical Alignment (VA)—that could resolve these wea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
