Fog display. A fog display, fog screen, vapor screen or vapor display is a system that uses haze machines or water vapor to create a semi-transparent wall, or "curtain" of suspended particles which trapped in a thin sheet ( laminar flow) of air and are illuminated by a projector, [1] in order to produce a display whose images seem to float in ...
Fog computing, also called edge computing, is intended for distributed computing where numerous "peripheral" devices connect to a cloud. The word "fog" refers to its cloud-like properties, but closer to the "ground", i.e. IoT devices. [ 6] Many of these devices will generate voluminous raw data (e.g., from sensors), and rather than forward all ...
Volumetric display. A volumetric display device is a display device that forms a visual representation of an object in three physical dimensions, as opposed to the planar image of traditional screens that simulate depth through a number of different visual effects. One definition offered by pioneers in the field is that volumetric displays ...
Smoke screen. Soldiers advancing under the cover of a smoke screen during a training exercise. A smoke screen is smoke released to mask the movement or location of military units such as infantry, tanks, aircraft, or ships . Smoke screens are commonly deployed either by a canister (such as a grenade) or generated by a vehicle (such as a tank or ...
on system. Major technologies are CRT, LCD and its derivatives ( Quantum dot display, LED backlit LCD, WLCD, OLCD), Plasma, and OLED and its derivatives (Transparent OLED, PMOLED, AMOLED). An emerging technology is Micro LED. Cancelled and now obsolete technologies are SED and FED .
A liquid-crystal display ( LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly [ 1] but instead use a backlight or reflector to produce images in color or monochrome.
Optical bonding is the use of an optical-grade adhesive to glue a glass to the top surface of a display. The main goal of optical bonding is to improve the display performance under outdoor environments. This method eliminates the air gap between the cover glass and the display. [ 2] Moreover, anti-reflective coating is often used in optical ...
Heliodisplay. The Heliodisplay is an air-based display using principally air that is already present in the operating environment (room or space). The system developed by IO2 Technology in 2001 uses a projection unit focused onto multiple layers of air and dry micron-size atomized particles in mid-air, resulting in a two-dimensional display ...
