Range recommendations from manufacturers are the most modest of the groupings. For the minimum (or nearest) viewing distance, they recommend a view angle of approximately 31 degrees; and for the maximum, a view angle as low as 10 degrees. [35] [36] A 10-degree view angle is approximately the angle that NTSC television was typically viewed from ...
With LCD screens, some manufacturers have opted to measure the contrast ratio and report the viewing angle as the angle where the contrast ratio exceeds 5:1 or 10:1, giving minimally acceptable viewing conditions. The viewing angle is measured from one direction to the opposite, giving a maximum of 180° for a flat, one-sided screen.
The unit interval is the minimum time interval between condition changes of a data transmission signal, also known as the pulse time or symbol duration time. A unit interval (UI) is the time taken in a data stream by each subsequent pulse (or symbol). When UI is used as a measurement unit of a time interval, the resulting measure of such time ...
A unit of time is any particular time interval, used as a standard way of measuring or expressing duration. The base unit of time in the International System of Units (SI), and by extension most of the Western world , is the second , defined as about 9 billion oscillations of the caesium atom.
The viewing cone refers to the effective viewing directions of an LCD display, as seen from the eye. This collection of angles resembles a cone. The concept has been introduced as an international standard ISO 13406-2, which defines it as the range of viewing directions that can safely be used for the intended task without "reduced visual performance".
This distance varies as the window moves, being maximal for some window position. This maximal distance is known as MTIE for the given observation interval. Plotting MTIE vs. different observation interval duration gives a chart useful for characterizing the stability of the clock.
Improves [quantify] diagonal viewing angle and further reduce response time to 5 ms. [citation needed] Professional IPS: P-IPS: 2010: Offer 1.07 billion colours (30-bit colour depth). [citation needed] More possible orientations per sub-pixel (1024 as opposed to 256) and produces a better [quantify] true colour depth. Advanced High Performance ...
The remaining vertical blanking interval lines are typically used for datacasting or ancillary data such as video editing timestamps (vertical interval timecodes or SMPTE timecodes on lines 12–14 [57] [58]), test data on lines 17–18, a network source code on line 20 and closed captioning, XDS, and V-chip data on line 21.
