Ultra-high-definition television (also known as Ultra HD television, Ultra HD, UHDTV, UHD and Super Hi-Vision) today includes 4K UHD and 8K UHD, which are two digital video formats with an aspect ratio of 16:9. These were first proposed by NHK Science & Technology Research Laboratories and later defined and approved by the International ...
The display resolution or display modes of a digital television, computer monitor, or other display device is the number of distinct pixels in each dimension that can be displayed. It can be an ambiguous term especially as the displayed resolution is controlled by different factors in cathode ray tube (CRT) displays, flat-panel displays ...
Extended Display Identification Data. Extended Display Identification Data ( EDID) and Enhanced EDID ( E-EDID) are metadata formats for display devices to describe their capabilities to a video source (e.g., graphics card or set-top box ). The data format is defined by a standard published by the Video Electronics Standards Association (VESA).
16:9. 8,294,400. 7680 × 4320. 8K UHDTV. 4320p. 33,177,600. Many of these resolutions are also used for video files that are not broadcast. These may also use other aspect ratios by cropping otherwise black bars at the top and bottom which result from cinema aspect ratios greater than 16∶9, such as 1.85 or 2.35 through 2.40 (dubbed ...
Plasma displays are bright (1,000 lux or higher for the display module), have a wide color gamut, and can be produced in fairly large sizes—up to 3.8 metres (150 in) diagonally. They had a very low luminance "dark-room" black level compared with the lighter grey of the unilluminated parts of an LCD screen.
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 ...
The first commercial displays capable of this resolution include an 82-inch LCD TV revealed by Samsung in early 2008, [45] the Sony SRM-L560, a 56-inch LCD reference monitor announced in October 2009, [46] an 84-inch display demonstrated by LG in mid-2010, [47] and a 27.84-inch 158 PPI 4K IPS monitor for medical purposes launched by Innolux in ...
Color temperature is a parameter describing the color of a visible light source by comparing it to the color of light emitted by an idealized opaque, non-reflective body. The temperature of the ideal emitter that matches the color most closely is defined as the color temperature of the original visible light source.
