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 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".
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]
[61] [62] The first wall-mountable LCD TV was introduced by Sharp Corporation in 1992. [63] Hitachi also improved the viewing angle dependence further by optimizing the shape of the electrodes (Super IPS). NEC and Hitachi become early manufacturers of active-matrix addressed LCDs based on the IPS technology. This is a milestone for implementing ...

PLS technology was Samsung's wide-viewing angle LCD technology, similar to LG Display's IPS technology. [25] Samsung asserted the following benefits of Super PLS (commonly referred to as just "PLS") over IPS: [26] Further improvement in viewing angle; 10 percent increase in brightness; Up to 15 percent decrease in production costs; Increased ...
