In display technology parlance, viewing angle is the angle at which a display can be viewed with an acceptable visual performance. In a technical context, the angular range is called viewing cone defined by a multitude of viewing directions .
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".
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 following table compares cathode-ray tube (CRT), liquid-crystal display (LCD), plasma and organic light-emitting diode (OLED) display device technologies. These are the most often used technologies for television and computer displays.

The introduction of TN-effect displays led to their rapid expansion in the display field, quickly pushing out other common technologies like monolithic LEDs and CRTs for most electronics. By the 1990s, TN-effect LCDs were largely universal in portable electronics, although since then, many applications of LCDs adopted alternatives to the TN ...
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]
LED's can be soldered to a flexible PCB strip to form LED tape popularly used for decoration. Common package shapes include round, with a domed or flat top, rectangular with a flat top (as used in bar-graph displays), and triangular or square with a flat top. The encapsulation may also be clear or tinted to improve contrast and viewing angle.
