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. A display ...
Berthier's diagram: A-B=glass plate, with a-b=opaque lines, P=Picture, O=Eyes, c-n=blocked and allowed views (Le Cosmos 05-1896)The principle of the parallax barrier was independently invented by Auguste Berthier, who published an article on stereoscopic pictures including his new idea illustrated with a diagram and pictures with purposely exaggerated dimensions of the interlaced image strips ...
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".
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).
As abovementioned, a camera's angle of view depends not only on the lens, but also on the image sensor or film. Digital sensors are usually smaller than 35 mm film, and this causes the lens to have a narrower angle of view than with 35 mm film, by a constant factor for each sensor (called the crop factor).
While THX still contends that the optimum viewing distance is a position where the display occupies a 40-degree view angle for the viewer, they too provide a range recommendation. The minimum viewing distance is set to approximate a 40-degree view angle, and the maximum viewing distance is set to approximate 28 degrees. [26]

For instance, a fog display using multiple projectors can render a 3D image in a volume of space, resulting in a static-volume volumetric display. [ 11 ] [ 12 ] A technique presented in 2006 does away with the display medium altogether, using a focused pulsed infrared laser (about 100 pulses per second; each lasting a nanosecond ) to create ...
